More specifically, the polyester / cellulose / spandex blended fabric is partially hydrolyzed with an alkaline agent (for example, caustic soda). The present invention relates to a polyester / cellulose / spandex mixed woven fabric suitable for clothing, which has a reduced amount by being decomposed and has a soft texture by loosening the intersections of the warp and weft yarns of the woven fabric, and a method for producing the same.

によっては不満な面が残されていた。2. Description of the Related Art Stretch fabrics using spandex use stretched processed yarns as weft yarns, widen the width during weaving to allow for shrinkage in the dyeing process from the raw fabric, and sufficiently perform the dyeing process. Manufactured by shrinking.
Therefore, since the shrinkage is larger than that of the woven fabric which does not use the elastic fiber by the amount required for the extensibility of the product, the feeling of ground thickness is increased and the texture is hard. For this reason, unsatisfactory surfaces are left depending on the use.

いを与える点で好ましい。As described above, the present invention has the greatest feature in that the polyester / cellulose / spandex mixed woven fabric is subjected to a weight reduction treatment. Here, the weight of the polyester is reduced, but the weight of the spandex is not reduced, which is a condition in which the weight loss of the polyester is 3 to 30% at a temperature of 80 to 105 ° under an alkali-hydrolyzable alkaline condition. A condition in which the physical properties hardly change. The weight-reduction processing of polyester hydrolyzes the surface with an alkaline chemical, eliminates the intuition of the fiber itself, and imparts a silky texture with a drape property by loosening the woven fabric itself due to the thinness of the fiber accompanying the weight reduction. As a result, the ground feeling and the hard feeling of the above three-way mixed fabric are significantly reduced. Thus, the texture of the blended fabric becomes soft due to the effect of the tapered polyester, but the tapered polyester is preferably present in the vicinity of the spandex from the viewpoint of elasticity and giving a softer texture.

囲に留められる。As the alkaline agent used for such processing, any one can be used as long as it can hydrolyze the polyester with alkali, but generally, it is caustic soda, caustic potash or the like. From the viewpoint of effectiveness, the weight loss rate of the fiber must be at least 3%, preferably 5% or more, more preferably 10% or more. However, excessive weight loss lowers the strength of the woven fabric, so that it is usually limited to a range of up to 30%.

Spandex is a highly elastic fiber, or polyurethane fiber. The form of mixing of the three-way mixed fabric is not particularly limited, such as mixed spinning, mixed fiber, and mixed weave, but a fabric using a composite yarn in which spandex is a core yarn and polyester and cellulose are sheath yarns is preferable. In the case of this woven fabric, the polyester is thinned by the weight reduction process to cover the spandex, and the looseness of the woven structure and the elasticity of the spandex yarn are utilized to give a unique soft texture.

が可能となる。As is clear from Table 1, as the alkali reduction processing is increased, the hard feeling of the fiber is decreased and the texture is improved. This is because the polyester hydrolyzes from the surface and the polyester denier thins, so
This is because the clearance at the intersection of the warp and weft of the woven fabric is increased, and the degree of freedom regarding movement of the warp and weft when compressed by a hand or the like is improved and the hard feeling is reduced. By the method of the present invention, the texture of the polyester / cellulose / spandex mixed fabric can be adjusted to some extent, so that the yarn count used and the restriction on the design are alleviated, and the production of fabrics for a wide range of applications becomes possible.
