Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a woven fabric having high breathability and excellent cooling comfort when worn, and a garment using the woven fabric.

[0002]

2. Description of the Related Art Recently, the heat of summer in Japan has been increasing. It is true that most people are suffering from heat on moist and hot days or hot summer days, although the discomfort varies depending on the type of clothes worn. In the case of a salaried worker who usually wears a tie on his shirt regardless of the season, the neck is tightened around his neck, so there is almost no air inside the clothes, and the air that is damp due to sweating is inside the shirt. Accumulate in. This heat is very painful in the summer.

Further, in recent years, many shirts which are generally commercially available have been processed to have antibacterial and deodorant properties and form stability. Since this processing uses a resin, the voids between the fiber tissues are filled, the air permeability is deteriorated, and further discomfort during wearing due to sweat and stuffiness is increased.

Japanese Patent Laid-Open No. 11-124701 proposes a shirt for improving these discomforts. This is to increase the breathability of clothes by using a mesh material for the shirt. For example, it can be considered that it is also effective because summer clothes that are worn in temples and the like use gauze and gauze tissue. However, in the case of an ordinary shirt, this method inevitably allows the skin or underwear to show through, which is a practical obstacle in terms of aesthetics when worn.

A method for reducing the sticky feeling and stuffy feeling caused by sweating when worn is proposed in Japanese Utility Model Publication No. 57-5988 and Japanese Utility Model Publication No. 54-76801. These are all triple layers with fibers with excellent water absorption placed directly on the skin side, other different fibers laminated on top of that, and a third layer for evaporating the absorbed sweat on top. It features a woven structure. Since the point is placed on sweat absorption and sweating, the cloth has a triple structure and is thick, and an effect in terms of breathability cannot be expected.

[0006]

As described above, the prior art is effective in sweat absorption and transpiration, but it has a poor breathability, so that it is stuffy, and has a good breathability but poor aesthetics. However, it was not satisfactory in terms of breathability, sweat absorption / transpiration and aesthetics.

[0007] An object of the present invention is to provide a woven fabric having high breathability, excellent cooling comfort when worn, and excellent aesthetics.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Details of the refreshing fabric of the present invention and clothes using the same will be described below. The cooling fabric of the present invention has a woven structure in which spun yarns and twisted multifilament yarns are arranged adjacent to each other in one or both of the warp and weft directions. This is because the spun yarn and the twisted multifilament yarn are arranged adjacent to each other, so that a gap can be obtained between the two yarns.

Further, since they are arranged adjacent to each other, irregularities are formed on the surface of the cloth, the contact area with the skin when worn is reduced, the stickiness is reduced, and a refreshing feeling can be obtained. In addition, by using spun yarn, it is possible to improve water absorption (sweat) / hygroscopicity and further improve the feel to the wearer.

Due to the above effects, the use of spun yarns and twisted multifilament yarns alternately arranged in both warp and weft increases the number of gaps between the weaving yarns and the unevenness of the fabric surface, thereby obtaining a refreshing fabric. It is possible and more preferable.

The present invention will be described in more detail below.

First, the composition type of the spun yarn used in the present invention includes synthetic fibers or semi-synthetic fibers such as polyester, polyamide and rayon, and short fibers such as natural fibers such as cotton and hemp. From the viewpoint of hygroscopicity, 100% natural fiber or a mixed yarn of natural fiber and other short fibers is preferable. Furthermore, it is more preferable to use 100% cotton or a mixed yarn of cotton and polyester short fibers because of its excellent water absorption and hygroscopicity and practicality.

Next, as the composition type of the twisted multifilament yarn in the present invention, long fibers made of synthetic fibers such as polyester, polyamide and rayon or semi-synthetic fibers can be mentioned. Polyester for which processing techniques such as false twisting and fluid turbulence processing (so-called Taslan processing) are established is more preferable.

Further, the multifilament yarn preferably has a modified cross-section yarn as the single yarn cross-sectional shape. This is because the use of the modified cross-section yarns creates voids between the individual yarns and improves the water absorption due to the capillary phenomenon. In addition, since the voids between the single yarns are larger, the multi-lobed cross-section is more preferable among the irregular cross-sections.

Further, as the form type of the multifilament yarn, thick thin yarn, fused yarn, etc. are preferable. This is because when the spun yarn is arranged, the gap between the yarns becomes larger. The thick thin yarn here is a multifilament consisting of a single yarn having alternating thick and thin portions in the longitudinal direction of the fiber, one of which is thick and thin yarn. Further, the fusion-bonded yarn has a part which is not untwisted by fusing in the longitudinal direction of the multifilament and a part which is untwisted because it is not fused It is a multifilament in which thick portions that are not fused and thin portions that are fused are alternately arranged.

Further, the multifilament yarn used in the present invention preferably contains a ceramic. This is because a cooling effect when the woven fabric comes into contact with the skin, that is, a contact cooling sensation effect is obtained. The content thereof is preferably 1 to 7% by weight, more preferably 2 to 6% by weight. This is because if the ceramic particles such as titanium oxide are less than 1% by weight, the cooling effect is poor, and if the amount exceeds 7% by weight, there is a problem in the spinnability of the raw yarn for clothing, which is not preferable.

Further, the multifilament yarn used in the present invention preferably has a twisting coefficient of 2,000 to 18,000, more preferably 2,000 to 15,000.
Is. This is to give an effect to the tailored silhouette.

The level of the twisted yarn is calculated by the following equation, α = T × D ^1/2, where the number of twists is T (t / m), the fineness of the multifilament yarn is D (decitex), and the twist coefficient is α. To be done.

Next, the arrangement of the spun yarn used for the warp and the twisted multifilament yarn will be described.

The arrangement of the spun yarn and the twisted multifilament yarn used for the warp in the present invention is 2: 2 to 6: 2, and more preferably 2: 2 to 4: 2. This is less than 2: 2 (eg 1: 0, 0: 1, etc.)
Is not preferable because the air permeability tends to decrease. Further, even if it exceeds 6: 2 (for example, 7: 2, 6: 3, etc.), the air flow rate tends to decrease, which is not preferable.

Furthermore, the arrangement of the spun yarn used for the weft and the twisted multifilament yarn is 1: 1 to 4: 4, and more preferably 1: 1 to 2: 2.
If it is less than 1: 1 (for example, 1: 0, 0: 1, etc.), the ventilation amount tends to decrease, which is not preferable. If it exceeds 4: 4 (for example, 5: 5, 6: 6, etc.), the water absorption and hygroscopicity increase due to the increase in the number of spun yarns, but the air flow rate tends to decrease, and there is less unevenness on the fabric surface. Therefore, the surface becomes flat and the sticky feeling tends to increase, which is not preferable.

Arrangement of spun yarn and twisted multifilament yarn 2: 2 to 6: 2 means that two spun yarns and two multifilament yarns to six spun yarns and two multifilament yarns are alternately arranged. 2: 2 means that two spun yarns and two filament yarns are alternately arranged, and 6: 2 means that six spun yarns and two filament yarns are alternately arranged. It is to be. For 2: 2,
The arrangement order is two spun yarns-two filament yarns, and in the case of 1: 1, one spun yarn-one filament yarn is an alternating arrangement.

Further, it is preferable that the cooling fabric of the present invention has an air permeability of 70 to 150 cc / cm ² / sec. More preferably 80 to 140 cc / cm ² / se
c, more preferably 90 to 130 cc / cm ²
/ Sec. According to the wearing test conducted by the present inventors, this shows that the general wearer feels that the ventilation amount is 70.
This is because the result is cc / cm ² / sec or more. However, if it exceeds 150 cc / cm ² / sec, the air flow rate will increase, and the wearer can feel that it is cool, but the density of the fabric itself becomes coarse and the skin or underwear can be seen through, which is a problem in terms of aesthetics. It is not so preferable because it exists.
