(Point of interest)
With the spread of the new coronavirus from the end of last year, coughing etiquette and hand washing are strongly recommended, people refrain from going out as much as possible, and when they have no choice but to go out, they are required to wear a mask. The lifestyle of people has changed significantly, and many people who had no habit of wearing masks before now have to wear masks all at once. So, although cloth masks that can be washed and used repeatedly have come in handy, masks made of non-woven fabric, cotton, synthetic fibers, etc. absorb moisture from your breath and get stuffy if you wear them for a long time. However, the heat from the skin is not dissipated, making it difficult to continue wearing it in the middle of summer due to stuffiness, and the fibers rub against the skin under high temperature and humidity conditions. There is concern about the occurrence of various troubles, such as an increased risk of heatstroke.

(conventional technology)
Reflecting this situation, it is not that there have not been some proposals that could serve as breakthrough measures.
For example, as typified by the one proposed in Patent Document 1 (1) below, in a skin contact product containing a fibrous material as an essential material, sericin is disposed at least on the surface that comes into contact with the skin. When the product is used by directly adhering to the surface of the skin for a long time, or when used for directly rubbing or wiping the surface of the skin, the sericin added to the product acts on the stratum corneum of the skin to maintain an appropriate level of moisture. It is formed of nonwoven fabric containing silk protein sericin as a fibrous skin contact product such as a mask and as a mouth cover as seen in Patent Document 1 (2), which exhibits excellent effects such as prevention of skin rash and rough skin. A moisture-retaining sheet is used, and a water-retaining sheet impregnated with a polymer-absorbing material is arranged on the outer side of the moisture-retaining sheet, and the water-retaining sheet absorbs and retains moisture from exhaled air, thereby relieving the throat, lips, and mouth. A moisturizing agent capable of moisturizing the surrounding area, imparting a moisturizing effect to the skin around the mouth with a moisturizing sheet, and activating cells, and is particularly suitable for use in closed rooms of passenger transportation means such as aircraft. A mask, or a mask material having a five-layer structure in which the mask materials are provided in order from the surface to the outermost layer, the outer layer, the intermediate layer, the inner layer, and the innermost layer, as shown in Patent Document 1 (3). wherein the outermost layer, the outer layer, the inner layer, and the innermost layer are silk fabrics, the intermediate layer is nonwoven fabric, the outermost layer and the outer layer constitute an outer double fabric, and the inner layer and the innermost layer constitute an inner double fabric is composed of, is difficult to unravel even after washing, etc., is highly durable, and has good breathability in spite of its heavy texture and touch, and a mask using the same scattered.

However, the fibrous skin patch material as shown in the former Patent Document 1 (1) is immersed in an aqueous solution of sericin, squeezed out and dried, and then gauze and diapers used for medical purposes, or certain An absorbent structure made of a thick cellulose fiber material, a cushioning foam sheet, or the like is wrapped with a covering fiber material, and as the covering fiber material, a part of sericin is left on the fiber surface in the silk scouring process. Although a sweat-absorbing pad using a fabric made of silk thread is shown, the specific structure of the mask is not shown, and sericin does not contribute to the filter performance of the mask.

The moisturizing mask of Patent Document 1 (2) includes a moisturizing sheet that serves as a mouth cover and has moisturizing properties, and a Tapyrus (registered trademark, hereinafter abbreviated) filter that overlaps the outer surface of the moisturizing sheet and cuts microscopic particles. , a heat-adhesive sheet made of a heat-adhesive nonwoven fabric and overlapping the outer surface of the tapyrus filter, a water-retaining sheet impregnated with a superabsorbent polymer and overlapping the outer surface of the heat-adhesive sheet, and a front cover of the water-retaining sheet. The moisturizing sheet is made of gauze that overlaps the outer side of the mouth, and the moisturizing sheet that comes into contact with the outer peripheral surface of the mouth is made of nonwoven fabric containing sericin. The material of the tapyrus filter is polypropylene, The heat-adhesive sheet is made of a heat-adhesive nonwoven fabric (trade name “ES Fiber” manufactured by Chisso Corporation), and the water-retaining sheet is impregnated with a polymer metal salt of an acrylic acid polymer, It has a fatal drawback that it cannot meet the needs of consumers who prefer natural materials because artificial materials are frequently used in various parts.

In addition, in the mask material represented by Patent Document 1 (3) and the mask using the same, the two layers on the front side form an outer double fabric, and the two layers on the back side form an inner double fabric. Therefore, it is difficult to unravel even after washing, and although it has good breathability despite its heavy texture and touch, the outermost, outer, inner, and innermost silk fabrics It is a patterned fabric woven by a jacquard loom, and the nonwoven fabric of the intermediate layer is preferably either a high-density nonwoven fabric or an embossed nonwoven fabric, and the material of the nonwoven fabric is not described. General non-woven fabrics with ventilation holes set to about 1 μm, such as filters made of high-density polyethylene non-woven fabrics, which do not allow PM (particulate matter) 2.5 to pass through and are breathable. However, two layers of silk fabric are provided on each of the front side and the back side, and a high-density non-woven fabric is sandwiched between the two layers, so pollen, dust, and bacteria can be prevented. On the other hand, the ventilation resistance increases, and when the wearer is active, it becomes difficult to breathe, and it is difficult to release heat and moisture. For example, there is a risk that it will become difficult to regulate the body temperature.

(problem awareness)
As described above, in the various fiber skin preparations, moisturizing masks, mask materials, and masks using the same that have been proposed so far, silk fabrics having sericin are in direct contact with the wearer's skin. The action of sericin protects the skin in the contact area and provides a skin-beautifying effect, and the filter that removes pollen and viruses has fine ventilation holes made of various metal fibers. Non-woven fabric is used, and the non-woven fabric made of the chemical fiber hinders the excellent breathability of the silk fabric, making it stuffy and hot while wearing it, making it difficult to breathe and painful. However, in a high humidity environment, excessive stress may be applied to the skin, causing problems such as rough skin and eczema. In view of the current situation where there is no such thing as silk fiber, we have developed a new product that maximizes the effectiveness of silk fibers with sericin, makes them more comfortable to wear, and more effectively removes pollen, dust, bacteria and viruses. This made me keenly aware of the possibility of developing silk masks.

(Purpose of Invention)
Therefore, the present invention provides a mask filter using a new silk fiber that provides a feeling of wearing that is gentle on the skin, and provides excellent breathability, heat dissipation, moisturizing properties, and skin-beautifying effects, and a mask technology using the same. After judging that it would be impossible to develop a floss cotton multi-layer filter with a new structure, we quickly embarked on its development and research. , a new manufacturing method thereof, a silk filter mask with a new structure using the same, and a new manufacturing method have been successfully realized. The configuration will be described in detail along with an example.

It is a multi-layer filter made of floss that is characterized by a structure in which these single-layer filters made of floss are bonded together.

In other words, a multi-layered floss filter having this basic structure consists of one silkworm cocoon, a layer of sericin α that is easily soluble in water from the surface of the cocoon thread to the deep layer of febroin, Among the three layers of sericin consisting of a layer of sericin β, which is less soluble in water than a layer of sericin α, and a layer of sericin γ, which is the least soluble in water, one cocoon cotton in which at least the layer of sericin γ is left, The necessary number of floss single-layer filters, which are developed into a single thin film without applying stress due to mechanical processing, corresponds to the required number of 2 sheets being 2 layers, or 3 sheets being 3 layers, or more. A filter made of 100% floss cotton, which is superimposed in a multi-layered film form of several layers, and the cocoon threads of each overlapping layer are entangled with each other, and the single layer filters made of floss are bonded together via sericin. When worn to cover the nose and mouth, dust, pollen, bacteria and viruses contained in the air are absorbed by the sericin on the surface of the cocoon thread, and only the purified air can be breathed.

That is, silkworm cocoons are soaked in at least one of white water at 60° C. to 100° C. or lye, which is an organic substance at 60° C. to 100° C. and weakly alkaline and has a pH of 8 to 11, for 30 to 60 minutes. A layer of sericin α, which is easily soluble in water, from the surface layer to a deep layer extending to febroin, a layer of sericin β, which is less soluble in water than the layer of sericin α, and a layer of sericin γ, which is the least soluble in water. The cocoons were boiled so as to leave at least the layer of sericin γ or to leave 99% to 10% of the total sericin, and one obtained cocoon cotton was washed with water. , while submerging in water, the cocoon filaments are loosened to remove the pupae and the molted shell, and then the fingertips are put on the inside of the cocoon cotton to expand it into a flat square film, which is then pulled out of the water, With the water-soaked cocoon cotton, the crossing points of the imaginary diagonals of the unfolded flat square membrane are covered from the tip of the streamlined mold and spread toward the bottom to create a single-layer floss filter for the first layer. In this state, another piece of cocoon cotton obtained by boiling the cocoons in the same manner is covered from the outer surface as a single-layer floss filter for the second layer in the same procedure as above, and the floss for the first layer is covered. Lay it on the outer surface of the cotton single layer filter to form a two-ply floss single layer filter, and if necessary, follow the same procedure to make a third layer or more layers. The outer surface is sequentially covered so that it becomes a multi-layered floss single-layer filter, and after stacking three or more layers, it is removed from the streamlined mold, dried naturally , and these are stacked. The cocoon threads are entangled and adhered to each other through sericin between each floss single-layer filter, and excessive stress is applied by mechanical processing during the process of manufacturing the floss single-layer filter from the cocoon cotton. A method for manufacturing a floss multi-layer filter, the gist of which is a configuration that does not include

As described above, according to the floss multi-layer filter of the present invention, unlike the conventional one, it expands and expands from one silkworm cocoon into a film shape from the unique characteristic configuration as described above. Two layers of floss single-layer filters, or three layers of three layers, or layers according to the number of layers according to the number of layers are superimposed in a multilayer film form. Multiple layers of single-layer filters can prevent the passage of even finer particles, and when the moisture of the breath that passes through is absorbed, the sericin on the surface of the cocoon thread generates adsorption power, dust, pollen, bacteria and viruses. In addition, the cocoon thread has high breathability, UV resistance (sun protection), constant temperature maintenance (heat retention, heat dissipation), and constant humidity maintenance. (Moisture retention, moisture release) and deodorant properties prevent the growth of bacteria, provide beautiful skin, retain heat, prevent heat buildup, and prevent excessive moisture and excessive dryness. It is an excellent feature that it can exhibit exceptional performance as a filter for masks, such as being able to

In addition, the floss multi-layer filter of the present invention uses two silkworm cocoons for two layers, three silkworm cocoons for three layers, and more. Since a large number of silkworm cocoons are used in the multi-layered product, it is easy to manage the number of silkworm cocoons in the manufacturing process and quality control, and manual production efficiency is improved. Further, the manufacturing method of the floss multi-layer filter of the present invention uses hot water at 60°C to 100°C, or organic substance at 60°C to 100°C and weakly alkaline lye at pH 8 to pH 11.

By cocoon treatment, a large amount of sericin can be left in the cocoon threads, so even after repeated washing with a neutral detergent, sericin is retained abundantly, resulting in high air permeability and UV resistance over a long period of time. (sunscreen), constant temperature maintenance (heat retention, heat dissipation), constant humidity maintenance (moisture retention, moisture release), and deodorant properties can be provided.

Furthermore, according to the method for producing a multi-layer filter made of floss of the present invention, after the boiling cocoon treatment, one piece of the cocoon cotton consisting of one cocoon is picked up and submerged in water to loosen the cocoon threads together. After opening the portion of the cocoon cotton close to the pupa and removing the pupa and the molted shell, the fingertips of the left and right index fingers and thumbs were placed on the inside of the cocoon cotton, and the cocoon yarns were attached to each other. The cocoon filament is expanded and developed into a square-planar film against entanglement, pulled out of the water, and in a state in which the cocoon filament contains water, an imaginary diagonal line of the planar quadrilateral film of the cocoon filament. The intersection point is arranged at the tip of the streamlined mold, and the edge of the outer periphery of the cotton floss is spread toward the bottom of the streamlined mold into a uniform film to form a floss single-layer filter. Due to the process, each cocoon can be carefully hand-crafted, and the sericin on the surface of the cocoon thread of the cocoon cotton is not given excessive stress, and while it is protected as gently as possible, silk 100 with excellent quality. In addition to being able to manufacture a filter of 100%, a single layer filter made of floss is superimposed in the form of a multilayer film, and the cocoon threads are entangled with each other through sericin to form an adhesive state, so each floss It is possible to obtain a special effect that it is possible to more reliably prevent the single-layer filters from being displaced or separated.

At least the sericin γ layer is left in three layers of sericin, which are stacked in the order of a layer of α, a layer of sericin β which is less soluble in water than the layer of sericin α, and a layer of sericin γ which is the least water soluble, or Or silk that is cut from a silk fabric in which 10% to 99% of the total sericin is left, so that the mask lining fabric in contact with the wearer's skin retains sericin abundantly. Because it is made of woven fabric, it is lighter and softer than non-woven fabrics, chemical fiber fabrics, or cotton fabrics. , constant temperature maintenance (heat retention, heat dissipation), constant humidity maintenance (moisture retention, moisture release), and deodorant properties, and the texture of silk can be maintained even after repeated washing with a neutral detergent for a long period of time. It is gentle on the wearer's skin and provides excellent sun protection and skin-beautifying effects.

Then, the built-in floss multi-layer filter and at least the mask back fabric of the mask front fabric or the mask back fabric absorb moisture in the wearer's breath and moisture in the air and dissolve slightly through sericin. The cocoon threads are entangled and adhered to each other, and the floss multi-layer filter and at least the mask lining fabric are bonded to each other. There is an effect that it is possible to more reliably prevent shifting, biasing, and splitting due to overlapping washings and the like.

In addition, according to the method of manufacturing a silk filter mask incorporating a multi-layer floss filter of the present invention, the mask surface is sewn with two straight stitches at the seams of the arc peripheral edges of the nose mouth cover parts of the pair of left and right front fabrics. The strength of the joint between the left and right ends of the mask front fabric is increased, and the durability strength is further enhanced.In addition, the seam allowance of the arc peripheral edge of the nose mouth covering part of the pair of left and right single back fabrics. is used as the mask lining fabric with one straight stitch, and the range of the left and right nostril cover parts centering on the position where the inner surface of the mask lining fabric is 1/2 between the left and right edges and 1/2 between the upper and lower edges The multi-layered floss filter is arranged so as to form a circular shape that fits inside, and the multi-layered floss filter is placed directly above the throat plate of the sewing machine, and the mask lining fabric is arranged so that it becomes the presser plate of the sewing machine. , By performing a single straight stitch along the seam allowance of the arc peripheral edge of the nose and mouth cover, the bonding strength in the center between the left and right ends of the mask lining fabric is increased, and the floss multi-layer filter is also It can be combined and the production efficiency can be improved.

There must be.

The cocoon is the raw material of the cocoon cotton in this invention. It is bound together in a bag around the circumference, more specifically, Seihaku, Koishimaru, which is a native Japanese species, Kyokuko, an improved species, and Chugoku. Shokei, a native species of the species, Hiko, an improved species, Choyo, a native species of European species, Italy Kouken, Turkish yellow cocoon ( any one or any of a variety of breeds, such as (Turkey), native species of Southeast Asian species Pure Mysore, other geographical breeds, hybrids, mutants, common silkworm breeds, limited breeds, etc. It is possible to use a plurality of types, and in other words, it is possible to use either one or both of the cocoons of domestic silkworms and the cocoons of wild silkworms.

One piece of cocoon floss becomes a single layer filter made of floss cotton. More specifically, as shown in Examples described later, a layer of sericin α that is easily soluble in water from the surface layer of the cocoon thread to the deep layer of febroin, and the layer of sericin α. It can be said that at least the sericin γ layer is left in three layers of sericin consisting of a layer of sericin β which is less soluble in water than sericin β and a layer of sericin γ which is the least soluble in water. Silkworm cocoons are soaked in at least one of white water at 60°C to 100°C or organic substance at 60°C to 100°C and weakly alkaline lye at pH 8 to pH 11 for 30 to 60 minutes. Among sericins in which three layers are superimposed in the order of a layer of sericin α, which is easily soluble in water, a layer of sericin β, which is less soluble in water than the layer of sericin α, and a layer of sericin γ, which is the least soluble in water, at least It can be said that it is obtained by boiling the cocoons so that either the sericin γ layer is left or 99% to 10% of the total sericin is left, and more preferably, sericin α. layer of sericin is left, in other words, the cocoon is boiled so that 99% to 70% of the total sericin is left.

Cocoons differ from white domesticated silkworms in that they have yellow, orange, and red colored cocoons derived from carotenoid pigments in mulberry leaves, which are produced by the original silkworms. It is possible to manufacture a multi-layered filter made of floss as cotton and use it as a silk filter mask with a mask outer fabric and a mask back fabric of the same color, but a colored floss multi-layered filter is made of the same colored floss. There is a risk that the carotenoid pigment will be eluted during repeated use and washing of the silk filter mask, which has a different color tone than the multi-layer filter, and the mask surface and back fabric of the silk filter mask will be colored. In particular, when lining a silk filter mask dyed in a color different from the carotenoid pigment, such colored cocoons are gently washed with a neutral detergent or the like at the stage of being made into cocoon cotton by boiling cocoon processing. It is preferable that the dye component is washed away and then washed with water to remove the neutral detergent, and a dye removal process is performed so as to obtain a white or unbleached color.

Cocoon filament is about 1,500 m in length and about 10 to 20 μm (1.5d to 4.0d) in width (1.5d to 4.0d), which is spewed out by silkworms to make cocoons. It varies depending on the breed of silkworms and rearing conditions). The febroin and the sericin are composed of proteins consisting of more than 10 kinds of amino acids, the febroin has the property of being difficult to dissolve in hot water and alkaline solutions, and the sericin has the property of being easily soluble in water and alkaline solutions, The sericin consists of three layers: a layer of sericin α, which is easily soluble in water, a layer of sericin β, which is less soluble in water than the layer of sericin α, and a layer of sericin γ, which is the least soluble in water, from the surface layer to the deep layer of febroin. It can be said that it is a thing.

Sericin is easily soluble in water, has the function of exhibiting adhesive strength when dried, and has the effect of making the surface of the cocoon thread smooth and glossy. Essential proteins are produced by synthesizing amino acids, and can be said to be essential ingredients for maintaining healthy skin. It activates hair matrix cells, inhibits tyrosinase activity, and suppresses melanin pigment.

A floss single-layer filter is made by processing cocoon cotton obtained from one silkworm cocoon into a single thin film, and a plurality of such sheets are superimposed to form a floss multi-layer filter that forms the basis of the present invention. It serves as a filter, and more specifically, one cocoon cotton having sericin on the surface layer of the cocoon yarn is spread into a thin film. More specifically, the surface layer of the cocoon yarn. Sericin consisting of three layers: a layer of sericin α, which is easily soluble in water, a layer of sericin β, which is less soluble in water than the sericin α layer, and a layer of sericin γ, which is the least soluble in water, from deep layers from to febroin. It can be said that one cocoon floss with the layer of sericin γ left unrolled in the form of one sheet of thin film.

In addition, the single-layer filter made of floss is prepared by adding 30 silkworm cocoons to at least one of plain hot water at 60°C to 100°C or lye, which is an organic substance at 60°C to 100°C and weakly alkaline and has a pH of 8 to 11. Soak for 60 to 60 minutes, and from the surface layer of the cocoon filament to the deep layer of febroin, a layer of sericin α, which is easily soluble in water, a layer of sericin β, which is less soluble in water than the layer of sericin α, and a layer of sericin γ, which is the least soluble in water, in this order. The cocoons are boiled so as to leave at least the layer of sericin γ in the three overlapping layers of sericin, or to leave 99% to 10% of the total sericin, and the obtained cocoon fluff is washed with water. After washing, one cocoon cotton consisting of one cocoon is picked up and submerged in water to loosen the binding of the cocoon yarns, and the part of the cocoon cotton close to the pupa is opened with fingers, and the pupa and After the peeled shell was removed, the left and right index fingers and thumbs were placed inside the hole formed when the pupa and the peeled shell of the cocoon cotton were taken out, and the cocoon threads were adhered to each other. The cocoon filament is expanded and developed into a square-planar film against entanglement, pulled out of the water, and in a state in which the cocoon filament contains water, an imaginary diagonal line of the planar quadrilateral film of the cocoon filament. It is possible to manufacture by arranging the intersection at the tip of the streamlined mold and stretching the edge of the outer periphery of the cotton floss toward the bottom of the streamlined mold to form a uniform film. is.

The cocoon treatment must be carried out so as to leave at least a layer of sericin γ or leave 99% to 10% of the total sericin, in other words, the fibroin of the cocoon filaments is exposed to the outside. For example, it can be soaked in hot water at 90°C to 100°C for about 10 minutes and then exposed to running water. Drop the cocoons in hot water, put a drop lid on, let steam pass through the cocoons, bring to a boil, remove the lid, expose the cocoons to the outside air for about 30 seconds, put the drop lid back on, and boil for about 3 minutes at 100°C. ℃, then turn off the heat, remove the drop lid, pour cold water over it, put the drop lid back on, ignite it again and keep it at 100 ° C for 5 to 6 minutes, turn off the heat and leave it for about 1 minute, then drop it. It can be done according to the procedure of removing the lid and pouring cold water, but in order to obtain good quality cocoon cotton with a large amount of sericin left, as shown in the examples described later, plain hot water at 60 to 100 ° C. is used. or lye, which is an organic substance at 60° C. to 100° C. and weakly alkaline and has a pH of 8 to 11, for 30 to 60 minutes.

The cocoon cotton (cocoon filament) is most preferably boiled so that the sericin α layer in the outermost layer is left, and the cocoon is boiled so as to leave the intermediate sericin β layer as much as possible. It must be boiled so that at least the deepest layer of sericin γ remains.

Lye shares the function of promoting the dissolution of sericin in the process of boiling cocoons. It is desirable to use clean water such as well water, spring water, tap water, etc., and weak water such as sodium carbonate (soda ash), sodium bicarbonate (baking soda), or sodium silicate (water glass). Alkaline chemical agents can be substituted, so soap scouring, soap-soda scouring, or soda scouring can be performed in addition to lye scouring.

For the streamlined mold, the fingertips of the left and right index fingers and thumbs are placed on the inside of the cotton floss, and the cocoon floss is expanded into a flat square film, and the expanded cotton floss is further shaped into a circular thin film-like floss single-layer filter. In addition to being a cannonball-shaped one with outer dimensions that is wrapped by the cotton single-layer filter, it may be a hemispherical shape with outer dimensions that is wrapped by the cotton single-layer filter. It can be made of wood, resin, metal, ceramics, ceramics, rattan, bamboo, leather, or other materials, and can be made of water-absorbing materials, such as wood. material, it is preferable that the outer wall of the range covered with the floss single-layer filter is coated with a waterproof membrane or a waterproof film.

The method for producing a multi-layered floss filter is as follows: boiling the cocoons, washing the obtained cocoon floss with water, picking up one cocoon floss consisting of one cocoon, submerging it in water, and separating the cocoon filaments from each other. After loosening the binding of the cocoon cotton, opening the part of the cocoon cotton near the pupa with the fingers, removing the pupa and the molted shell, hooking the fingertips of the left and right index fingers and thumbs to the inside of the cocoon yarn, The cocoon filament is expanded and developed into a planar quadrilateral film against the entanglement of the cocoon filament with adhesive force, and then pulled out of the water to form a planar quadrangular cocoon filament while the cocoon filament contains water. Arrange the intersection of the film-like virtual diagonal lines at the tip of the streamlined mold, and spread the edge of the outer periphery of the cocoon floss toward the bottom of the streamlined mold in a uniform film shape, A floss single-layer filter is obtained. Next, one piece of cocoon filament consisting of one cocoon is taken by hand, submerged in water to loosen the cocoon threads, and the portion of the cocoon filament close to the pupa is removed with fingers. After removing the pupa and the molted shell, the fingertips of the left and right index fingers and thumbs are placed on the inside of the cotton floss, and the cocoon floss is flattened against the entanglement of the cocoon threads with the adhesive force. After being expanded and developed into a quadrangular film shape, it is pulled out of the water, and in the state where the cocoon cotton contains water, the intersection of the imaginary diagonal lines of the plane quadrilateral membrane of the cocoon cotton is placed on the floss single-layer filter. From above, it is placed at the tip of the streamlined mold, and the edge of the outer periphery of the floss is spread toward the bottom of the streamlined mold to form a uniform film, and a total of two floss It is possible to stack the single layer filters made of floss, remove them from the streamlined mold, and dry them so that the cocoon threads are entangled with each other through sericin between the single layer filters made of floss cotton to form an adhesive state. .

In addition, the method for producing a multi-layered filter made of floss includes the process of boiling the cocoons, washing the obtained cocoon floss with water, and then, for example, picking up one cocoon floss consisting of one cocoon and submerging it in water. While loosening the cocoon threads together, open the portion of the cocoon cotton close to the pupa with the fingers, remove the pupa and the molted shell, and then place the fingertips of the left and right index fingers and thumbs inside the cocoon cotton. Then, the cocoon fluff is expanded into a square-planar film against the entanglement of the cocoon filaments with adhesive force, and then pulled out of the water. The point of intersection of the imaginary diagonals of the planar quadrangular membrane of cotton is arranged at the tip of the streamlined mold, and the edge of the outer periphery of the cocoon cotton is directed toward the bottom of the streamlined mold to form a uniform membrane. to form a floss single-layer filter, then pick up one piece of cocoon filament consisting of one cocoon, submerge it in water to loosen the cocoon filaments of the cocoon filament, After opening the part near the pupa and removing the pupa and the molted shell, the fingertips of the right and left index fingers and thumbs are put on the inside of the cocoon cotton to resist the entanglement of the cocoon threads with the adhesive force. After the cocoon floss is expanded and developed into a planar quadrangular film, it is pulled out of the water, and with the cocoon floss still containing water, the intersection of the imaginary diagonal lines of the planar quadrangular film of the cocoon floss is applied to the floss. From above the single-layer filter, place it on the tip of the streamlined mold, spread the edge of the outer periphery of the cotton floss toward the bottom of the streamlined mold in a uniform film shape, and total A multi-layer filter made of floss is formed by superimposing two single-layer floss filters, and further, one piece of floss consisting of one cocoon is picked up by hand, submerged in water to loosen the cocoon threads, and After opening the portion of the cocoon cotton close to the pupa and removing the pupa and the molted shell, the fingertips of the left and right index fingers and thumbs were placed on the inside of the cocoon cotton, and the cocoon yarns were attached to each other.

It is possible to ensure high quality without damaging the layers.

As shown in FIGS. 13 to 22, the floss multi-layer filter 1 of the present invention is embedded between the mask back fabric 5 and the mask front fabric 4 of the silk filter mask 3, and the silk filter mask 3 is When worn so as to cover the nose and mouth, dust, pollen, bacteria, viruses, etc. contained in the air are adsorbed by the sericin S on the surface of the cocoon threads 11, 11 intertwined in the form of a multilayer thin film of the floss multilayer filter 1. , it is possible to breathe only purified air, and furthermore, the sericin S on the surface layers of the cocoon threads 11, 11 of the cotton multi-layer filter 1 absorbs moisture contained in exhaled air passing through the cotton multi-layer filter 1. It absorbs moisture, releases moisture when the outside air dries, exhibits excellent moisture retention and moisture release, and is comfortable to wear.

In addition, since the cotton multi-layer filter 1 has antibacterial (bacteriostatic) properties, it prevents the growth of various bacteria, suppresses the generation of ammonia due to various bacteria, prevents the generation of sweat odor, and eliminates body odor and the like. It absorbs odors, exerts deodorizing properties, keeps the skin clean, can prevent atopic dermatitis, etc., has UV resistance, reflects and absorbs short wavelengths, and has the effect of preventing sunburn. It has a constant temperature maintenance property with excellent heat retention and heat dissipation, softens the difference between cold and hot, maintains a temperature close to body temperature, realizes more comfortable wearing, and the elasticity of cocoon cotton 10 When exhaled, the temperature and humidity increase, generating a small amount of negative ions, providing a refreshing feeling of forest bathing, promoting blood circulation, preventing hypothermia, and reducing collagen. In addition to preventing allergic reactions, the negative ions are expected to combine with histamine to alleviate allergic symptoms.

In addition, since the floss multi-layer filter 1 is one in which the sericin S of the cocoon threads 11 are adhered to each other, even when it is placed inside the silk filter mask 3, it does not easily lose its shape. Even if the silk filter mask 3 moves and becomes uneven or dispersed, simply by applying an external force to the silk filter mask 3 so that it becomes homogeneous with the fingertips, the exhalation and the outside air will pass through. When moisture is absorbed, the sericin S of the cocoon threads 11 is slightly loosened and recombined, and can be easily restored to its original state. In the case of a silk fabric with sericin S left on the surface layer, the three layers of the floss multi-layer filter 1, the mask front fabric 4 and the mask back fabric 5 are bonded together via the sericin S of the cocoon threads 11. As a result, it is possible to more reliably prevent bias and dispersion of the floss multilayer filter 1.
