Description

[Detailed description of the invention]

[Industrial Field of Application] The present invention relates to a method for producing adhesive cloth by applying a powdered adhesive to a cloth or knit product in an arbitrary pattern using an electrophotographic method. [Prior Art and Problems] In the process of sewing clothes, one or more pieces of cloth or knitted products are folded or overlapped to be sewn. At that time, basting stitches are applied to prevent the folded or overlapping parts from shifting. For basting, a basting sewing machine is used and the fabric or knit product must be moved over a wide range in two dimensions. Also, for aesthetic reasons, it is necessary to remove the basting thread after lock stitching. On the other hand, when the above-mentioned folded portions or overlapping portions are (temporarily) bonded using an adhesive, a method such as sandwiching a tape-shaped adhesive and bonding under heat is used. Both methods require manual labor, making it difficult to speed up and automate the sewing process. In addition, adhesive interlining is a field in which adhesives are frequently used in the field of sewn products. Adhesive interlining generally has a fixed dot pattern or
A material in which powdered thermoplastic resin is randomly sprinkled and fused is used. However, with these interlinings, adhesive is uniformly fused to the entire surface of the fabric, and adhesive can be freely fused at the required concentration to fabrics of various shapes and sizes in the required areas. let me,
It is not sufficient to meet the needs of small-lot, high-mix adhesive processing. In this way, in the field of sewn products, there is a need to devise a method for applying adhesive in a predetermined pattern to fabrics cut into various shapes during processes such as fabric pre-treatment. has been done. [Means for Solving the Problems] The present inventors have conducted intensive research to solve these conventional problems, and have arrived at the present invention. That is, the present invention uniformly charges a conductive photoreceptor layer provided on a conductive conductor by corona discharge, and exposes the charged surface of the photoreceptor to light in an arbitrary pattern, thereby reducing the exposure on the charged surface. An electrostatic latent image of the pattern, which is an unexposed area with a large amount of surface charge remaining on the surface of the photoreceptor layer, is formed by reducing the electric charge of the area, and the electrostatic latent image is charged to a polarity opposite to that of the electrostatic latent image. Use a powder adhesive, or use a powder adhesive that forms an electrostatic latent image of the pattern, which is the exposed portion with reduced surface charge, and is charged to the same polarity as the electrostatic latent image. The powdered adhesive image formed on the surface of the photoreceptor by visualizing the electrostatic latent image is directly electrostatically transferred to cloth or knitted products, or electrostatically transferred to the surface of another medium. After electrotransferring, the pattern is retransferred to a cloth or knitted product to prepare an adhesive cloth with the adhesive attached in the pattern, and the adhesive can be heat-fused to the cloth or knitted product or not. To provide a fabric bonding method characterized in that a part of the bonded fabric is folded and stacked, or another fabric or knit product is stacked and heated to fuse the adhesive. In the present invention, by using the principle of a copy printing device, a method of forming a latent image of an arbitrary figure at high speed can be used as a printing system using an electrophotographic method, such as a laser printer, for example. It is possible to form an electrostatic latent image by converting an electrical signal generated from a pattern generator into an optical signal and irradiating the photoreceptor with a laser beam. As a method other than irradiating with laser light, a method of irradiating an optical signal with an optical fiber tube, etc. can be used. In addition, by using a copying machine, for example, by using technology that utilizes enlarged or reduced latent images of an original image of a certain shape, adhesives can be applied to original images such as patterns used in the sewing field. It is also possible to perform processing to distinguish between brightness and darkness of the area to be coated, and to optically form the reflected light of the original pattern as an electrostatic latent image on the photoreceptor. In addition, by digitizing images, it is also possible to use images that are composites and composites of various original patterns, electrostatic latent images formed on photoreceptors based on various pattern information read by image recognition devices, etc. . The method of the present invention utilizes these electrophotographic methods and utilizes an electrostatic latent image formed on a photoreceptor,
This is a method for attaching an adhesive to cloth and then bonding the cloth by heating. To visualize an electrostatic latent image, there are two methods: a method using a powder having a charge polarity opposite to the polarity of the surface charge of the electrostatic latent image formed on the photoreceptor (so-called normal development method), and a method using photosensitive material. There is a method (so-called reversal development method) using a powder having the same polarity as the polarity of the latent image on the body. Generally, in printers, parts corresponding to black backgrounds such as characters and figures are illuminated, and a light beam is irradiated onto a photoreceptor in the form of an electrical signal converted into an optical signal.
A method is used in which the area corresponding to the white background area is treated as a dark area and is not exposed to light. In this method, the surface potential of the background area is higher than that of the character/graphic area, and a powder having the same polarity as the surface of the photoreceptor must be used to visualize the latent image. On the other hand, in a copying machine system that uses reflected light from the original image, the part corresponding to the black background of the character figure has a higher surface potential than the background part, and the powder has a charge polarity opposite to the surface potential polarity on the photoreceptor. Manifested by the body. Electrification is imparted to the powder by rubbing adhesive powder with magnetic powder such as iron powder or other inorganic powder, but depending on the skeletal structure, functional groups, etc. of the resin that makes up the powder, The charge polarity and charge amount are also controlled by. Furthermore, if necessary, the charge polarity and charge amount of the resin can be controlled by adding various dyes, etc., and desirably a colorless to light-colored to white charge control agent is used. The amount of charge can also be controlled by adjusting the surface treatment agent for the magnetic powder. Commonly used photoreceptors include amorphous selenium and its alloys (such as selenium/tellurium), cadmium sulfide, organic dye composites, and amorphous silicon. The polarity of the surface charge is selected and used depending on the degree of ease of access of the holes to the conductive layer on the backside of the photoreceptor. For example, in the case of an amorphous selenium-based photoreceptor, a method is used in which a positive electrostatic latent image is formed on the surface of the photoreceptor which is uniformly charged to a positive polarity by irradiating light in a bright area. In such a case, regular development is performed using negatively charged powder. In the present invention, as the resin constituting the powder adhesive, a negatively charged resin (for example, a polyester resin) or a positively charged resin (for example, an aminoacrylic modified resin) is selected.
It is possible to control the charge polarity of a powder adhesive by adding an appropriate amount of dyes with a charge adjustment function to the resin, and this method can be applied to any combination of photoreceptor and development method. be. The average particle size of the powder adhesive required for visualization depends on the thickness of the fibers constituting the cloth, the smoothness of the woven or non-woven fabric, the roughness of the weave, etc., but a particle size of 5 to 1000 μm is used. , preferably 10 to 300 μm. The amount of powder attached to the photoreceptor depends on the surface potential of the photoreceptor, the amount of exposure (exposure wavelength, exposure intensity, exposure time, etc.),
It is adjusted by the bias voltage during development, the charge amount of the powder, and the particle size. The method of transferring the visualized powder adhered on the photoreceptor to a cloth or knitted product is to bring the cloth (or knitted product) close to the photoreceptor, and apply a corona discharge, etc. from the opposite side of the cloth. A method in which the cloth is charged to a polarity opposite to that of the powder, and the powder is transferred to the cloth by electrostatic attraction.A medium having an insulating surface is brought close to the photoreceptor, and the opposite side of the medium surface is charged. By applying a method such as corona discharge, the contact body is charged to a polarity opposite to that of the powder, and the powder is electrostatically transferred to a medium by electrostatic attraction. A method of electrostatically transferring the powder onto the cloth by applying a method such as corona discharge from the opposite side of the cloth; By electrostatically transferring the powder onto a medium using a method such as applying corona discharge from the opposite side of the surface of There are methods such as fusing powder to cloth and transferring it with heat or pressure, and the transfer method can be selected depending on the material and shape of the cloth or knit product. In this way, it is possible to obtain a cloth with powdered adhesive adhered in a pattern, but it is not necessary to handle the cloth in an unfused state unless you are stacking another cloth, etc. and thermally bonding it. In some cases, if the powder is not fixed to the fabric, it will fall off during post-processing or other handling of the fabric. The powder can be fused to the fabric using radiant heat from a heat oven, passed through heated rollers that have been treated to release the powder, or fused using a heat press that has been treated to release the powder. It can be fixed. The powder adhesive is preferably one that can be easily heat-fused, but since the powder is charged by friction with magnetic powder etc. at the stage of visualizing the latent image, caking etc. may occur at normal temperatures. It must not occur and reduce the fluidity of the powder. When visualizing,
Usually, a sleeve made of magnetic powder and powder is formed using a rotating roll that has multiple magnetic poles inside.
The rotating sleeve brings the powder into contact with the photoreceptor, thereby causing the powder to adhere to the photoreceptor. Therefore, the powder must maintain an elastic modulus above a certain level at ordinary temperatures. In addition, a cascade development method using beads such as glass or iron balls can also be used to visualize inorganic powder by frictional charging caused by gravity falling, and in this case, the abrasion resistance of the powder is also required. be done. A characteristic of this cascade method is that beads with large particle sizes can be used, and it is effective for triboelectrification and visualization of powder adhesives with large particle sizes. In this way, powdered adhesive is mixed with inorganic powder such as magnetic powder or beads and stirred, so
Materials that allow powder to easily fuse must be avoided. For adhesion of cloth, etc., the first substrate cloth, to which the powdered adhesive has been adhered or fused, prepared in this manner is superimposed on the second substrate, or the first substrate is bonded to the second substrate. By a method such as bending a part,
Bonding is achieved by passing these through a hot press or a hot roller. When heat-sealing resin to cloth, the heat-sealing must be carried out at a temperature, pressure, and time that will not damage the properties of the cloth (or fibers). A resin whose softening point is too low may be easily fused, but the fluidity of the powder at ordinary temperatures is poor. A material with a softening point that is too high is undesirable because it requires heating and fusing at a higher temperature. When directly heat-sealing powder-adhered cloth using a heat roller, the adhesive must not transfer to the heat roller.
This requires selection of the melt viscosity, especially the dynamic viscosity. In addition, when bonding cloth, it must be able to undergo thermal deformation at as low a temperature as possible, and must not seep out of the adhesive onto the back surface of the cloth due to excessive melt flow. In the present invention, as a method of bringing the cloth close to the photoreceptor and directly transferring the powder image from the photoreceptor to the cloth, there is a method as shown in FIG. 1, for example. That is, a photoconductive photoreceptor with a thickness of 5 to 100 μm selected from inorganic photoreceptors such as selenium, selenium/tellurium, selenium/arsenic, amorphous silicon, cadmium sulfide, and zinc oxide, and organic photoreceptors such as dye composites. While rotating the conductive drum 1 having the layer, the photoreceptor layer is uniformly charged by corona discharge in a dark place. An arbitrary pattern 2 is exposed thereon, and the charges on the exposed surface of the photoreceptor are discharged to the conductive substrate on the back side, thereby forming an electrostatic latent image of the above pattern on the photoreceptor. Powdered adhesive is stored in an adhesive box 3, charged with a rotating metal brush or brush 4 made of magnetic powder to an opposite charge to the electrostatic latent image, and is then charged by Coulomb force. It adheres to the electrostatic latent image on the drum. The adhesive adhered to the electrostatic latent image on the drum is transferred by a roller 5 onto a cloth or knit product 8 placed on a belt 6 driven at the same circumferential speed as the drum 1, with the belt 6 sandwiched between the drum 1 and the adhesive. The image is transferred by the Coulomb force from the electrode 7 on the opposite side, which is charged with the opposite polarity to that of the adhesive. Then, while moving on the belt 6, it is fixed onto an adherend heated by a heat source 9 such as infrared heating, high-frequency dielectric heating, or hot air. Alternatively, as shown in FIG. 2, the fabric or knit product is folded by the guide 11 without passing through the heating device or after passing through the heating device, or after being folded, the heated roll 1
Bending and adhering is performed by heat-pressing with 0. Furthermore, as shown in FIG. 3, a bonded fabric is produced by overlapping another fabric or knit product 8' and heat-pressing it with a hot roll 10. In the present invention, an adhesive cloth is manufactured by a method of bringing an insulating medium close to a photoreceptor, transferring a powder image from the photoreceptor onto the insulating medium, and then retransferring the powder image on the medium to the cloth. An example of the method is shown in Figure 4. The powdered adhesive transferred to the insulating belt 12 is transferred to the transfer roller 1 which has a corona charger inside.
3, 13', and is electrostatically transferred to cloth 8, and thermally fused to another cloth 8' by heat rollers 14, 14'.
15 adhesive fabrics are obtained. In the present invention, a releasable medium is brought close to a photoreceptor, a powder image is transferred from the photoreceptor to the releasable medium, and then the powder image on the medium is retransferred to the cloth. As a manufacturing method, there is one shown in FIG. 5, for example. That is, the powder adhesive adhered to the electrostatic latent image on the drum 1 is electrostatically transferred by the electrode 7 onto the release belt 16 which moves at the same circumferential speed as the drum 1. Then, the cloth or knitted product 8 fixed on the support belt 17 is brought into contact with the adhesive on the release belt 16 by a heat roll 18 and a pressure roll 19, and the adhesive is thermally transferred onto the cloth or knitted product. let As the electrophotographic technique used in the present invention, known methods can be used. As the developing method, it is possible to appropriately use both the conventionally known magnetic brush method and cascade method. Both methods are used depending on the particle size of the adhesive to be applied.For example, in order to charge an adhesive with an average particle size of 50μ or more and attach it to the surface of the photoreceptor layer, a carrier with an average particle size of 200μ or more is used. It is preferable to do so. In this case, when using the magnetic brush method, the magnetic poles with the magnetic force normally used cannot balance well with the gravity of the carrier, making it difficult to visualize the adhesive on the surface of the photoreceptor layer. There are cases. However, if a cascade method is used in which a developer (a mixture of carrier and powder adhesive) is caused to flow down by gravity for development, it is relatively easy to visualize an arbitrary pattern on the surface of the photoreceptor layer. When the average particle size of the adhesive is 50 μm or less, it is preferable to use a carrier with an average particle size of 50 to 200 μm, and a compact and versatile magnetic brush method can be used. Furthermore, by using a moisture-crosslinking thermoplastic resin powder with a hydrolyzable organosilicon functional group as an adhesive, moisture is added after heat bonding to form a crosslinked structure with siloxane bonds, resulting in heat resistance, solvent resistance, and heat resistance. It is also possible to produce adhesive fabrics with excellent water resistance. Such a moisture-crosslinkable thermoplastic resin having a hydrolyzable organosilicon functional group is, for example, represented by the general formula (1). (However, X is a hydrolyzable group such as an alkoxy group, an alkenyloxy group, an acyloxy group, an aminooxy group, an amino group, an oxime group, R' is a C ₁ to C ₄ alkyl group, R'' is a hydrocarbon group or N, Hydrocarbon group containing one or more different atoms of O and S, a is 0 to

Furthermore, by using a micro-encapsulated powder adhesive with different internal and external structures, it is possible to transfer the adhesive onto cloth by applying pressure. In this case, by using a resin with a relatively high softening point on the outside and a soft resin on the inside, it is possible to obtain an adhesive that is stable against frictional charging and easy to transfer under pressure.

〔Effect of the invention〕

According to the method of the present invention, dots are applied to cloth or knit products.
By applying a powdered adhesive according to an arbitrary pattern consisting of lines, planes, or a set of these, and heating and fixing the adhesive as it is, it is possible to create a shape-retaining effect on the cloth without using an interlining. Alternatively, after applying the adhesive, heat and press the fabric while folding it, or heat and press it while overlapping other fabrics.
By pressure bonding, adhesive cloth can be manufactured continuously and efficiently. As a result, it has become possible to omit the interlining pasting process and interlining sewing process, simplify the sewing process, and replace some sewing assembly processes with adhesive, which will play a role in automating and speeding up the sewing process. big. [Example] Examples are shown below, but the embodiments of the present invention are not limited thereto. Note that parts in the examples are parts by weight. Example 1 (Method of transferring with an insulating medium) 1 part of powder adhesive with an average particle size of 35μ and an average particle size of approx.
A developer was prepared from 100 parts of 400μ iron powder. The powder adhesive is made by coarsely crushing a copolyamide resin with a softening point of 130°C by the ring and ball method obtained from ε-caprolactam, adipic acid, sebacic acid, pyrazine acid, and hexamethylene diamine, and adding aniline black paint to 100 parts of the resin. Add 3 parts of Nigrosine BK (manufactured by Orient Chemical Co., Ltd.), melt and knead, freeze and crush,
Adjustment was made by wind classification. The charge amount of this developer by the blow-off method was 7 μc/g, which was a positive charge. After thoroughly pre-stirring 4,000 parts of the developer thus obtained, an electrophotographic photograph was taken using an optical fiber tube method using a commercially available printer (Showa Information Equipment S-840-K Printer System) modified with a pattern generation function. The developer was placed in the developing section of a type printing device, and the developer was sufficiently stirred in the cascade type developing machine. By adjusting the printer's control device, the line width is 0.8 mm, with dots divided into 32 dots per inch.
The pattern generator was adjusted so that a grid pattern consisting of vertical and horizontal lines with a space of 2.8 mm between lines was generated (in this case, the grid pattern part was irradiated with light by an optical fiber). ). The surface of the photoreceptor made of amorphous selenium is uniformly positively charged, and a polyester film cut into B4 size (volume resistivity 10 ¹⁶ Ω cm) is set in the paper feed section, and pattern-controlled light is applied. The signal was converted into dots using an optical fiber tube at a process speed of 64 mm/sec and an exposure time of 4.3 seconds.
After irradiating an A4 size grid pattern, developing it with a positively charged powder adhesive, and adhering the powder image onto the photoreceptor, move the polyester film into contact with the photoreceptor at the same peripheral speed. At this time, the powder image was transferred onto the polyester film by negative corona charge from a corona discharge wire placed on the back side of the polyester film. After removing static electricity from the polyester film, the polyester cut into A4 size paper is placed on the film with powder attached to it, which is moved to the conveyance section.
Cotton (65/35) broad cloth (surface resistivity ^10-14 Ωcm)
At the same time, the powder image was transferred to the broad cloth by placing the powder on the broad cloth and moving the corona charger set on the broad cloth. This broadcloth was peeled off from the polyester film, taking care not to disturb the powder image, and the amount of powder adhering to the broadcloth was determined to be 3.8 g/cm ² . On top of the powder-adhered broadcloth, another broadcloth cut into an A4 size sheet is layered, and passed through a heated roller (circumferential speed of 42 mm/sec) whose surface temperature is adjusted to 180°C. was glued. A part of this contact cloth was cut into specimens with a width of 25 mm and a length of 100 mm, and a peel test was performed at 20° C. at a tensile rate of 100 mm/min, which showed an average peel strength of 135 g/25 mm. Example 2 (Method of transferring with a releasable medium) A developer was prepared by the method of Example 1, and put into the developing unit of the electrophotographic printing device used in Example 1, and a similar grid pattern was generated. Adjustments were made. The surface of the photoreceptor was charged uniformly and positively, and the surface cut into B4 size sheets was silicon-treated release paper (manufactured by Tokushu Paper Co., Ltd., volume resistivity 8 x 10 ¹⁴ Ωcm, critical surface tension 23.2 dyne/cm). ) in the paper feed section, irradiate it with an A4 size grid pattern, adhere the powder image onto the photoreceptor using the positively charged powder adhesive, and release the release paper at the same peripheral speed as the photoreceptor. When the particles were brought into contact with each other, the powder image was transferred onto the release paper by negative corona charge from the back side of the release paper. Polyester/cotton (65/35) cut into A4 size paper is placed on the release paper with powder attached to the transport section.
A broad cloth is placed on the adhesive, passed through a heated roller whose surface temperature is adjusted to 180℃, the release paper is peeled off, and the powder adhesive is transferred to the broad cloth by thermal melting.
A cloth to which the adhesive was adhered in a grid pattern was obtained. The amount of adhesive adhered was 4.3 g/m ² . This broadcloth was layered with another A4-sized broadcloth and heat-pressed (150°C, 20 seconds) to adhere the fabrics together. The average peel strength was 165 g/25 mm. Example 3 10 parts by weight of a copolymerized polyester resin powder with a softening point of 115°C and an average particle size of 20μ as measured by the ring and ball method and triethoxysilyl modified with 3-isocyanatopropyltriethoxysilane at the molecular end A developer was prepared by dry blending 100 parts by weight of iron powder with a particle size of 100 μm. The developer was placed in a toner box of a commercially available copying machine (DC-162, manufactured by Sanda Kogyo Co., Ltd.), and the edges were fixed with sellotape on A4 size paper (polyester/cotton = 65/35).
The above-mentioned modified copolymerized polyester resin powder was uniformly transferred onto the cloth through a broad cloth (surface specific resistance: 10 ¹⁴ Ωcm), and was lightly fixed onto the cloth using an infrared lamp. Subsequently, a similar type of fabric was layered on top of the fabric, and the fabric was passed between two hot rolls heated to 160°C and pressed together to obtain an adhesive fabric. A part of the adhesive fabric was immediately cut into specimens with a width of 25 mm and a length of 100 mm, and a peel test was performed at 20°C at a drawdown speed of 100 mm/min, which showed an average peel strength of about 130 g/25 mm. . When the adhesive cloth was immediately ironed at 160°C and held for 1 minute, the adhesive seeped out onto the surface of the cloth and the texture became hard. The remaining adhesive fabric was left in a constant temperature and humidity test room at 25° C. and 65% humidity for 3 weeks, and then subjected to a similar heat resistance test by ironing. In this case, there was no seepage of the adhesive, and almost no change in texture was noticed. The average peel strength was about 160 g/25 mm. From these results, it was confirmed that thermoplasticity disappeared due to crosslinking of the adhesive due to moisture absorption, and heat resistance improved.
