AI Technical Summary

Benefits of technology

The invention provides a high-density woven fabric that is water-repellent and low-air permeable. It uses high twisted yarns to reduce the size of capillaries and minimize the formation of capillaries, and has excellent rub-resistant water repellency. The fabric has high-speed drying properties and low moisture retention, making it ideal for energy-efficient garments. It is also comfortable and easy to handle as a garment. The low-air-permeable high-density woven fabric has exceptional rub-resistant water repellency.

Problems solved by technology

In the case of dense weaving, the structure is highly restricted even during the scouring, relaxing or dyeing process, and thus it is even more unlikely that multifilament are disordered to break the capillary structure.
Such a capillary structure is dense because the fabric is densely woven, and thus it is difficult for water to penetrate into the woven fabric.
In particular, in the case where water-repellent treatment or the like is performed to make the multifilament surface highly hydrophobic, the penetration of water is even more difficult.
A high-density woven fabric of prior art using multifilament yarns as mentioned above, particularly a water-repellent fabric, has disadvantages in that although water hardly penetrates, when it is used, such as when it is worn, pressure or the like is applied, and thus once water penetrates, then water is held in the capillaries, making it difficult to dry.
Its low air-permeability due to high density has also been another cause of slow drying.
However, this high-density woven fabric is to prevent, during dense weaving with a fluid injection weaving machine using the warp without a glue, a significant decrease in weaving properties due to fluff resulting from single-yarn breakage in ultra fine filaments.
It does not provide a solution to the disadvantages of a high-density woven fabric of prior art, which is the elimination of water retention in capillaries to shorten the drying time after washing.
However, this high-density woven fabric does not provide a solution to the disadvantages of a high-density woven fabric of prior art either, which is the elimination of water retention in capillaries to shorten the drying time after washing.

reference example 1

[0039]A woolly filament yarn (single-yarn denier 1.04) of 75 denier / 72 filaments was twisted 2000 turns / M, and the resulting high twisted yam was used as the warp and weft. The fabric woven by the yams (an S-twist yarn was used as the warp, and an S-twist yarn and a Z-twist yarn were alternately used as the weft), was scoured, relaxed, dyed, and finished in a usual manner to give a low air-permeable high density warp mat plain-woven fabric of this reference example. This reference product had a warp density of 216 yarns per inch and a weft density of 86 yarns per inch. As a result of calculation, the twist coefficient of the high twisted multifilament yarns was 17321, and the cover factor of the entire woven fabric was 2615.

[0040]For comparison, the same woolly filament yarn (single-yam denier 1.04) of 75 denier / 72 filaments as in this reference example was used. As the warp, the yarn was weakly twisted 300 T / M to such a degree that problems in weaving would be avoided. Meanwhile, a...

example 1

[0044]The woven fabrics of Reference Example 1 and Comparative Example 1 were each subjected to water-repellent treatment with a fluorine-based water repellent agent (Asahi Guard AG-710, manufactured by Asahi Glass Co., Ltd.; a 7% aqueous solution was used) in a usual manner and then calendered to give Example 1 and Comparative Example 2. The following Table 2 shows the water-pressure resistance, water repellency, and rub-resistant water repellency of Example 1 and Comparative Example 2.

[0045]It was shown that in Example 1, rub-resistant water repellency. which is novel water repellency, is much higher than in Comparative Example 2.

reference example 2

[0046]In place of the woolly filament yarn (single-yarn denier 1.04) of 75 denier / 72 filaments used in Reference Example 1, a woolly filament yarn (single-yarn denier 0.52) of 75 denier / 144 filaments was S-twisted 2000 T / M, and the resulting high twisted textured yarn was used as the warp, while the same yarn as used for the warp was twisted 1500 T / M, and the resulting S-twist and Z-twist high twisted textured yarns were alternately used as the weft. The fabric woven by the yams was scoured, relaxed, dyed, and finished in the same manner as in Reference Example 1 to give a low air-permeable high-density warp mat plain-woven fabric of Reference Example 2. The woven fabric of Reference Example 2 had a warp density of 224 yarns per inch and a weft density of 84 yarns per inch. As a result of calculation, the twist coefficient of the warp high twisted multifilament yarn was 17321, the twist coefficient of the weft high twisted multifilament yarns was 12990, and the cover factor of the e...

Abstract

Provided is a low air-permeable high-density woven fabric that is less likely to get wet even in the rain and needs only a short drying time after getting wet or being washed. The low air-permeable high-density woven fabric is obtained by applying water-repellent treatment to a woven fabric containing high twisted yarns with a twist coefficient of 5100 or more in a proportion of 50% or more of the surface area of the woven fabric and has a air-permeability of 50 cc / cm2 / sec or less, a cover factor of 1500 or more, and a rub-resistant water repellency of 100 or more.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a high-density woven fabric for garment applications or for sundry applications in the living space, particularly relates to a low air-permeable high-density woven fabric using high twisted multifilament yarns.[0003]2. Prior Art[0004]Conventionally, for the purpose of obtaining a dense structure, most of high-density multifilament woven fabrics have usually used nontwisted yarns or weak twisted yarns that are twisted to such a degree that weaving properties are not impaired. In a woven fabric that uses nontwisted multifilament yarns having no twists or low-twist multifilament yarns 1 with a small number of twists, filament yarns forming the yarn are bundled in parallel with each other or in a similar state, whereby a large number of long capillaries 1a are formed in the woven fabric (see FIG. 1). In the case of dense weaving, the structure is highly restricted even during the scouring, r...
