Description

The present invention relates to a multi-layered woven fabric that has both high breathability and transparency resistance and has high transparency resistance even when stretched.

Breathability is required for summer materials to prevent stuffiness due to sweating. Breathability is ensured by creating a gap, and it is used for women's clothing, blouses, shirts, and the like.

However, with the above technique, there are many gaps in the fabric, so when wearing it directly on the skin such as shirts and blouses, or when wearing it on underwear, the undershirt and skin can be seen through the gaps, as if the fabric is transparent. It is not suitable for some applications because it is in a state where it can be seen. For example, there is a proposal to use a woven fabric of imitation tissue for a jacket having good breathability (Patent Document 1).

Further, in order to achieve both breathability and transparency resistance, a method has been proposed in which the misaligned portion of the structure of the imitation weave is shifted to a position contradictory between the front structure and the back structure (Patent Document 2).

Japanese Unexamined Patent Publication No. 09-228110 Japanese Unexamined Patent Publication No. 2006-225806

However, since the woven fabric disclosed in Patent Document 1 is mainly used as a jacket-like outerwear, it does not wear on bare skin and has insufficient transparency. Further, the woven fabric disclosed in Patent Document 2 has sufficient breathability and transparency resistance when normally worn, but if the fabric is stretched when crouching, the ventilation portion expands and the transparency resistance is improved. It was inadequate.

Therefore, it is an object of the present invention to provide a multi-layer woven fabric that has both high breathability and transparency resistance when normally worn, and also has high transparency resistance even when the fabric is stretched due to a change in posture.

An example of a structure diagram of a multi-layered woven fabric in which the tissue deviation caused by the surface imitation structure, which is a preferable form of the present invention, is arranged so as to be covered with a back thread is shown. The organization chart of the multi-layered woven fabric manufactured in the Example is shown. The organization chart of the multi-layered woven fabric manufactured in the Example is shown. The organization chart of the multi-layered woven fabric manufactured in the Example is shown. The organization chart of the multi-layered woven fabric manufactured in the Example is shown.

Hereinafter, the present invention will be specifically described.

It is important that the multi-layered woven fabric of the present invention has an air permeability of 30 to 200 cc / cm ² · sec. It is more preferably 40 to 200 cc / cm ² · sec, and even more preferably 50 to 200 cc / cm ² · sec. By setting the aeration amount within the above range, the outside air and the air circulation in the clothes are promoted when worn as clothes, and it is possible to prevent stuffiness due to sweating and an increase in body temperature due to exercise. If the aeration amount is smaller than 30 cc / cm ² · sec, it is difficult to obtain the above effect, and if it is larger than 200 cc / cm ² · sec, the body temperature may be excessively lowered and the comfort may be impaired.

It is important that the multi-layered woven fabric of the present invention has a transparency resistance of 90% or more. More preferably 93-99%. More preferably, it is 95% to 99%. If the transparency is less than 90%, the underwear may become transparent when worn as clothing.

It is important that the multi-layered woven fabric of the present invention contains yarns having a twist number of 0 to 200 T / M. By including the above-mentioned yarn, the bulkiness of the yarn is increased, the air permeability of the fabric is improved, and the light scattering is enhanced, so that the transparency resistance is also improved. Furthermore, when the woven fabric itself is stretched according to the stretchability, it has high transparency resistance. More preferably, it contains a yarn having a twist number of 0 to 50 T / M, and more preferably, it contains a yarn having a twist number of 0 to 10 T / M. The number of twists referred to here is the number of revolutions of the yarn per meter measured by the method described later.

Further, by including the false twisted yarn and / or the crimped yarn in which the single fiber is composed of a side-by-side type as the yarn having a twist number of 0 to 200 T / M, the bulkiness of the yarn is further increased, and the light scattering effect is caused. In addition to the see-through property, the bulkiness is less likely to decrease even when the fabric is stretched, and it is preferable because an extremely high see-through property can be maintained.

As the false twisting method for producing the false twisting yarn, any commonly used method such as a pin type, a friction disc type, a nip belt type and an air twisting type can be adopted. As a form, it is a continuous multifilament yarn composed of a plurality of single fibers, and those having a uniform cross section in the length direction or those having a thick and thin cross section can also be used, and the cross section shape is a round cross section or a triangular shape. , Y type, X type, eight-leaf type, hollow type and flat irregular shape can also be used.

In the crimped yarn in which the single fiber is a side-by-side type fiber, polymers having different intrinsic viscosities and copolymerization rates are bonded together along the length direction of the fiber. , Highly crimped. The intrinsic viscosity and the copolymerization ratio are not particularly limited. As the form, it is preferable that the continuous multifilament yarn is composed of a plurality of single fibers, and those having a uniform cross section in the length direction or those having a thick and thin cross section can also be used. As the cross-sectional shape of the single fiber, a round cross section, a daruma type, a triangular shape, a Y type, an eight-leaf type, and an indeterminate flat shape can also be used. Further, such a crimped yarn can be further subjected to false twisting and used.

As for the fineness of the yarn having a twist number of 0 to 200 T / M, those having a fineness of 0.8 to 1.5 times that of other constituent yarns are preferably used from the viewpoint of transparency resistance. Within this range, it is possible to obtain extremely excellent see-through resistance without becoming too bulky and causing twitching.

Further, in the multi-layered woven fabric of the present invention, the ratio β / α of the degree of exposure α observed from one side of the warp or weft to the degree of exposure β observed from the other side is larger than 1.2. It is preferable to include X and a yarn Y having β / α of 1.0 or less.

By including a thread X having a ratio β / α of the degree of exposure α to one surface and an degree of exposure β to the other surface greater than 1.2, and a thread Y having a β / α of 1.0 or less. It is preferable because X can be preferentially arranged on only one surface and the transparency is improved by overlapping the threads. β / α is an index showing the bias of the degree of exposure to one surface of a certain yarn type.

It is preferable to use a yarn having a twist number of 0 to 200 T / M as the yarn X as described above.

The yarn X and the yarn Y are yarns selected from the warp yarns if they are warp yarns, and are selected from the warp and weft yarns if they are warp and weft yarns.

The yarns X and Y referred to here are treated as different yarns even if they are of the same yarn type but have a difference in twist coefficient of 5 or more, or yarns arranged in different layers.

Further, in the above-mentioned multi-layered woven fabric, it is preferable that the yarn X and the yarn Y satisfy the following (4).

(4) Absence of thread X (Kx) ≤ Absence of thread Y (Ky)
Kx: Existence of thread X K
Ky: Existence of thread Y K
Absence K = (fineness of the thread: dtex) × (number of threads of the thread / 2.54 cm)

Further, by setting the abundance of the yarn X (Kx) ≤ the abundance of the yarn Y (Ky), the yarn X is appropriately exposed and the air permeability can be ensured without impairing the see-through property, which is preferable. In the above, the degree of exposure represents the exposed area of the yarn per unit area, which is observed when the multilayer structure woven fabric is viewed from a certain surface for a certain yarn type. When there are a plurality of threads corresponding to the threads X and Y, the sum of the abundance degrees K of each is Kx and Ky.

Further, in the above-mentioned multilayer structure woven fabric, it is preferable that the yarn X and the yarn Y satisfy the following (5).

(5) The twist coefficient of the thread X is 16 or less, the twist coefficient of the thread Y is 30 or more, the twist coefficient of the thread X is 16 or less, and the twist coefficient of the thread Y is 30 or more, so that the bulkiness is small. It is preferable that the yarn Y forms a gap to improve the air permeability, and the yarn X having a large bulkiness covers the gap from one surface to impart transparency resistance. The yarn X may have a twist coefficient of 0.

The fiber material used for the multilayer structure fabric of the present invention is not particularly limited, and natural fibers such as cotton and linen, animal fibers such as wool, recycled fibers such as rayon, semi-synthetic fibers such as acetate, synthetic fibers such as polyester fibers, etc. Can be used. Further, the fiber form is not particularly limited such as spun yarn and filament, and spun yarn obtained by blending each material can also be used. Further, from the viewpoint of improving the see-through property, synthetic fibers that are relatively easy to contain inorganic particles and the like are particularly preferable.

The yarn having a twist number of 0 to 200 T / M is preferably used for both warp and weft, but is particularly preferably used for weft because it is easy to change the yarn type during weaving.

Further, it is preferable that the yarn having a twist number of 0 to 200 T / M is composed of a filament containing 1 wt% or more of inorganic particles from the viewpoint of improving the see-through property. The content of the inorganic particles in the yarn containing such inorganic particles is more preferably 2 to 15 wt%. When the content of the inorganic particles is in this range, the effect of improving the see-through property is extremely remarkable. The inorganic particles are not particularly limited, and examples thereof include silicon oxide, titanium oxide, alumina, barium carbonate, barium sulfate, and the like, and titanium oxide is particularly preferable from the viewpoint of transparency resistance.

The woven structure of the multi-layered woven fabric of the present invention is not particularly limited as long as the provisions of the present invention are satisfied, but at least one layer has a woven structure in which a portion having a large structure coefficient and a portion having a small structure coefficient are adjacent to each other. It is preferable to arrange threads of other layers so as to cover the tissue deviation. The structure coefficient (M) is calculated from M = (number of threads per complete structure) / (number of intersection points per complete structure), and when the structure is dense, the structure coefficient is small and the structure is sparse. It is said that the organization coefficient is large. Since the woven structure in which the portion having a large structure coefficient and the portion having a small structure coefficient are adjacent to each other is excellent in designability, it is preferable to arrange the woven structure on the side that can be seen, such as a surface structure. Further, a double weft structure is preferable because the weaving process is simple and the productivity is high. In addition, the structure of the table is preferably a structure that causes a tissue shift called mishasa, mock reno, pseudo-roast, and mekuri weave from the viewpoint of improving breathability, and it is preferable that the structure is misa weave from the viewpoint of productivity. More preferred. Further, the most preferable form is a weft double structure in which back threads are arranged so as to cover the tissue deviation generated in the front structure in order to maintain the air permeability and improve the see-through property.

The organizational deviation referred to here will be described below. Normally, the warps and / or wefts of a woven fabric are evenly arranged, but by arranging the part with a large structure coefficient and the part with a small structure coefficient next to each other, the warp and / or the warp and weft of the part with a small structure coefficient shifts to the part with a large structure coefficient. , The arrangement of the warp and / or the weft in the portion having a small structure coefficient is sparse, and the arrangement of the warp and / or the weft in the portion having a large structure coefficient becomes dense, so that the arrangement of the warp and / or the weft becomes uneven. The gap created by lowering the density of the warp and / or weft compared to other parts and sparsely arranging the warp and / or weft of the woven fabric is called tissue misalignment.

FIG. 1 shows an example of a structure diagram of a mishami structure, which is preferable as the table structure of the present invention. Further, FIG. 2 shows an example of a structure diagram of a multi-layered woven fabric arranged so as to cover the structure deviation caused by the surface mesher structure with a back thread, which is a preferable form of the present invention. Further, FIGS. 3 to 6 show an organizational chart of the multi-layered woven fabric.

The organization chart of FIG. 1 consists of a flat structure 2 having a small tissue coefficient and a 3/3 mat structure 3 having a large structure coefficient, and the threads constituting the flat structure 2 are displaced toward the 3/3 mat structure, so that the tissue is displaced at the boundary. 1a is formed. In the organizational chart of FIG. 2, the warp threads a, the weft threads A and B, and the weft threads C arranged as the back threads 2a cover the tissue deviation caused by the weft pattern. FIG. 3 is also arranged so as to cover the tissue deviation caused in the same manner as in FIG. 2 by the weft C arranged as the back thread 2a, but the frequency of the tissue deviation is low because the ratio of the plain weave is higher than that in FIG. .. FIG. 4 shows that the arrangement of the flat structure and the 3/3 mat structure is changed to reduce the gap due to the tissue deviation. In FIG. 5, the structure of the front is the same as that in FIG. 3, but the float of the weft C arranged as the back thread 2a is short. FIG. 6 shows that the arrangement of the flat structure and the 3/3 mat structure is changed to increase the number of places where the tissue shift occurs as compared with FIG. 2, and to reduce the gap due to the tissue shift.

Further, the warp and weft fabric preferably contains a yarn having a twist number of 0 to 200 T / M in the warp and weft, and a more preferable form includes a yarn having a twist number of 0 to 200 T / M in the back yarn of the warp and weft fabric. That is. By using a yarn having a twist number in the above range as a weft, it becomes easy to switch the yarn type at the time of weaving and the productivity is improved.

The multi-layered woven fabric of the present invention contains yarns having a twist number of 0 to 200 T / M, but other yarns may be used in combination.

Examples of the other yarns include natural fibers such as cotton and linen, animal fibers such as wool, regenerated fibers such as rayon, semi-synthetic fibers such as acetate, and synthetic fibers such as polyester fibers. Further, the fiber form is not particularly limited such as spun yarn and filament, and spun yarn obtained by blending each material can also be used. From the viewpoint of further improving the see-through property, it is particularly preferable to use synthetic fibers as other threads, which are relatively easy to contain inorganic particles in the fibers. Further, in the structure, it is preferable to arrange the portion having a high structure coefficient and the portion having a low structure coefficient forming the above-mentioned structure deviation as warp and / or weft of the adjacent woven structure because the gap becomes large and the air flow rate is improved.

It is preferable that the other yarn is composed of a filament containing 1 wt% or more of inorganic particles from the viewpoint of improving the see-through property. The content of the inorganic particles in the yarn containing such inorganic particles is more preferably 2 to 15 wt% in the yarn. If the content of the inorganic particles is small, the effect of improving the see-through property due to light scattering may decrease. The inorganic particles are not particularly limited, and examples thereof include silicon oxide, titanium oxide, alumina, barium carbonate, barium sulfate, and the like, and titanium oxide is particularly preferable from the viewpoint of transparency resistance.

When a yarn having a twist number of 0 to 200 T / M is used as the yarn X, it is preferable to use the other yarn as the yarn Y.

Further, the cover factor of the multilayer woven fabric of the present invention is preferably in the range of 1500 to 4500. If the cover factor is less than 1500, the structure becomes too sweet when the double weave is used, so that the transparency resistance may be lowered or the multiple weave may not be formed. Further, if the cover factor exceeds 4500, even if the woven fabric is made of multiple fabrics, the structure becomes too tight and it may not be possible to cause a structure shift. Therefore, it is a more preferable aspect to set the cover factor in the range of 1800 to 3000.

Here, the cover factor is expressed by the following equation.
Cover factor = N1 (D1) ^1/2 + N2 (D2) ^1/2
(In the formula, N1 represents the warp density (book / 2.54 cm), N2 represents the weft density (book / 2.54 cm), D1 represents the warp fineness (dtex), and D2 represents the weft fineness (dtex). , In the case of a multi-layer structure, the number of threads in all layers is used as the density)

In the present invention, by controlling the number of places where the tissue deviation occurs, the size of the gap caused by the increase / decrease, the fineness of the yarn arranged so as to cover the tissue deviation, and the bulkiness, the air permeability and the see-through resistance are controlled. The transparency resistance at the time of extension can be adjusted.

Further, in a preferred embodiment of the present invention, the multi-layered woven fabric of the present invention has a significantly improved see-through resistance at 10% elongation, and can achieve, for example, 90% or more. When the transparency is 90% or more, for example, when worn as a bottom, even if the posture changes and the fabric is stretched, the underlying fabric is difficult to see through, which is extremely preferable. It is also possible to achieve 93% to 99% in a more preferred embodiment of the invention and 95% to 99% in a more preferred embodiment. In order to keep the see-through property at the time of 10% elongation within the above range, it is preferable to include a bulky thread such as a conjugated thread or a processed thread from the viewpoint of imparting stretchability and imparting see-through property by light scattering. ..

The multi-layered woven fabric of the present invention thus obtained has high breathability and transparency resistance when normally worn, and also has high transparency resistance even when the fabric is stretched due to a change in posture. It can be preferably used for clothing such as jackets.

Hereinafter, the present invention will be described with reference to examples, but the present invention is not necessarily limited thereto.
