Benefits of technology

The present invention provides a high-transparency woven fabric that is strong enough for use in clothing and has low air-permeability. This results in a clothing or futon where the batting is see-through, providing an unprecedented look. The fabric is thin, light, and can be used for side clothes, down wear, and sleeping bags, among others.

Problems solved by technology

Thus, it is difficult to maintain the strength of the woven fabric.
Thus, they are not attractive.
However, the woven fabric of Patent document 1 is lacking in aesthetic merit since its reinforcing yarn looks longitudinal stripes or weft spots.
Thus, the woven fabric is not a woven fabric that can sufficiently express the beauty of a batting.
Thus, the woven fabrics do not have desired transparency.

example 1

[0099]Using the polymer chips of a relative viscosity of 3.5, wherein the relative viscosity was raised by solid-phase polymerization of nylon 6 having a relative viscosity of 2.2 and containing no titanium oxide (NY6, super bright) polymer chips (manufactured by Toyobo Co., Ltd.), the polymer chips were melted and spun from a spinning mouth having 7 round holes at a spinning temperature of 288° C. Setting three godet rollers in the spinning machine to 2000 m / minute (the first godet roller), 3500 m / minute (the second godet roller), and 3500 m / minute (the third godet roller) in the order from the upstream side and heating the second godet roller to 153° C., the yarn was extended. In this way, a multifilament was yielded which had a fineness of 11 dtex and was composed of 7 monofilaments each having a round cross-section. The breaking strength and the breaking elongation of the resultant multifilament were evaluated by the above-mentioned methods. The results are shown in Table 2.

example 2

[0102]The nylon 6 polymer chips having a relative viscosity of 2.2 were used and spun into a multifilament yarn having a total fineness of 22 dtex and composed of 20 monofilaments. In Example 2, a woven fabric was produced by the same method as in Example 1 except that the weave was changed to plain weave, and the woven fabric was dyed into beige by the above-mentioned method. The resultant woven fabric is evaluated in the same manner as in Example 1. The results are shown in Table 2.

example 3

[0103]A woven fabric was produced by the same method as in Example 1 except that the woven fabric described in Example 1 was dyed into gray. The resultant multifilament and woven fabric are evaluated in the same manner as in Example 1. The results are shown in Table 2.

Abstract

An object of the present invention is to provide a woven fabric having high transparency that a batting is made see-through, having a strength necessary for side clothes of clothing or futons, and further having a low air-permeability in order to provide an unprecedented clothing or futon whose batting is seen through. A woven fabric of the present invention is characterized in comprising a multifilament having a single yarn fineness of 0.5 to 3.0 dtex and a total fineness of 3 to 25 dtex, wherein the woven fabric has a cover factor of 1300 to 2500, a visible light transmittance of 25% to 80%, and an L* value of 37 or higher.

Description

BACKGROUND OF THE INVENTION[0001](1) Field of the Invention[0002]The present invention relates to a woven fabric having transparency, particularly to a woven fabric used suitably for a side cloth of a down wear, a down jacket, a futon (Japanese-style mattress), a sleeping bag or others.[0003](2) Description of Related Art[0004]A woven fabric used for a side cloth of a down wear or a feather futon is required to be high in woven fabric strength and low in air-permeability in order to restrain cotton or down from spouting out, while the woven fabric is prevented from being torn. Recently, the woven fabric is required not only to be merely low in air-permeability but also to be lighter, soft in feeling, and high in design and fashionability.[0005]However, in order to make a woven fabric light, it is indispensable to make the woven fabric thin or reduce the fineness of a multifilament constituting the woven fabric. Thus, it is difficult to maintain the strength of the woven fabric.[0006...
