Description

  The present invention relates to a cellulosic fabric excellent in wrinkle resistance even after repeated washing with water and excellent in wear comfort.

  The fabric made of cellulose fibers has many features such as high color development, unique texture, high moisture absorption and anti-static performance, and good sliding properties. There is a drawback that it is easy to become and inferior in strength. In order to remedy these drawbacks, various techniques for improving the shrinkage resistance and wrinkle resistance by applying resin crosslinking by post-processing have been studied. However, in the fabric using 100% cellulose fiber, washing in the home ( Hereinafter, it is also simply referred to as “washing with water.”) No wrinkle is generated afterwards.

As described in Patent Documents 1 and 2 below, for example, 100% cotton fabric is likely to wrinkle during washing and drying, and ironing is required. Therefore, glyoxal resin is usually used, and cellulose fibers It is common to apply anti-wrinkle treatment to
However, even with a woven fabric that has been subjected to such an anti-wrinkle process, the W & W property after washing and washing is about grade 3 or lower. For example, in a field where a smooth surface such as a lining is required, The fact is that ironing is required after washing and washing.

  On the other hand, as described in Patent Documents 3 and 4 below, a woven fabric using cellulose fibers and synthetic fibers for either warp and / or weft is known as a woven fabric utilizing the characteristics of both. In the case of these fabrics, fabrics that can be washed at home can be obtained, but since the mixing ratio of cellulose fibers is around 50%, it is difficult to say that the fabrics are sufficiently satisfactory from the viewpoint of texture, hygroscopicity, and antistatic properties. .

Patent Document 5 below proposes a method of treating the unwoven fabric with epoxy-modified silicone during resin processing in order to improve the wrinkle resistance when the mixing ratio of cellulose fibers is increased. As a result, an unwoven fabric having a cellulose fiber mixing ratio of 70% or more and a W & W property of 3.5 or more is obtained.
However, the treatment has a problem that the anti-wrinkle performance after washing is deteriorated by repeating washing five times or more.
Under such circumstances, there is a demand for the development of a cellulose fiber-containing fabric that has a high anti-wrinkle effect after repeated washing and washing at home, and is non-ironing and wrinkle-free, even if the fabric has a high cellulose fiber mixing ratio.

  [2] The woven fabric according to [1], wherein the cellulose fiber is a regenerated cellulose fiber.

[3] The cellulose fiber is represented by the following formula (1):
K = (0.9 × D) ^0.5 × T (1)
{In the formula, D means fineness (dtex), and T means the number of twists (t / m). }, The woven fabric according to the above [1] or [2], which is a cellulose continuous fiber having a twist coefficient (K) defined by: 2,000 to 15,000.

  [4] A lining made of the woven fabric according to any one of [1] to [3].

  [8] The method according to any one of [5] to [7], further including a water treatment step after the heat treatment step.

  [9] The method according to [8], wherein the water treatment step is a spreading treatment in warm water.

  The fabric of the present invention is a fabric with a high cellulose blend ratio and excellent hygroscopicity and antistatic performance, and also has excellent W & W properties after repeated washing and washing, and has an easy care property that allows sufficient washing and washing at home. It is a woven fabric. Therefore, the woven fabric of the present invention can be suitably used as a lining made of cellulose union lining or cellulose fibers having lining suitability.

Examples of cellulose fibers used in the present invention include natural cellulose fibers such as cotton and hemp, regenerated cellulose fibers such as cupra ammonium rayon and viscose rayon, acetate fibers, and purified cellulose fibers represented by lyocell. Regenerated cellulose fibers are preferred. If necessary, the yarn may be twisted or blended.
A single yarn fineness of 0.5 to 5.5 dtex, 20 to 100 filaments, and a total fineness of about 30 to 167 dtex are preferably used. In the case of spun yarn, yarns 20 to 80 can be used.

  The woven fabric of the present invention is a woven fabric in which cellulose fibers are used at least for warp and / or weft, and the cellulose fibers are arranged at 50% by weight or more (hereinafter also simply referred to as “mixing ratio”). When the mixing ratio of the cellulose fibers is less than 50% by weight, the characteristics of the cellulose fibers cannot be obtained, which is not preferable. The higher the mixing ratio of cellulose fibers, the more the characteristics of cellulose fibers can be utilized. The mixing ratio is preferably 70% by weight or more, more preferably 90% by weight or more, and particularly preferably 97% by weight or more.

When the twisting coefficient (K) exceeds 15,000, untwisting is easy, and it is not preferable because it is easy to generate wrinkles and a feeling of wiping, or the apparent fineness is lowered and the sense of sheer is increased. On the other hand, when the twist coefficient (K) is less than 2,000, the effect of the twisted yarn is hardly exhibited.

  In producing the fabric of the present invention, normal weaving conditions may be used. Examples of the fabric structure applied to the present invention include a plain structure, a twill structure, a satin structure, and a deformed structure thereof.
