Embodiment 1

[0050] A preparation method of wrinkled fabric, the steps are as follows:

[0051] (1) Preparation of crescent-shaped composite fiber: PET (intrinsic viscosity is 0.53dL / g) and PTT (intrinsic viscosity is 1.2dL / g) with a mass ratio of 50:50 are juxtaposed by FDY process and circular composite fiber (will The spinneret holes on the spinneret are changed from circular to crescent-shaped) to prepare crescent-shaped composite fibers; wherein, when preparing side-by-side composite fibers, PET melt and PTT melt are distributed from the same spinneret The spinneret m (crescent spinneret) and spinneret n (crescent spinneret) on the top are extruded;

[0052] The distribution refers to distributing the PTT melt through the distribution hole A, while distributing the PET melt through the distribution hole B to the spinneret m, distributing the PTT melt through the distribution hole C, and simultaneously distributing the PET melt through the distribution hole D To the spinneret hole n; ...

Abstract

The present invention relates to a preparation method of a wrinkled fabric. Crescent-shaped composite fibers as wrinkled warp raw materials and crescent-shaped composite fibers and cotton fibers as wrinkled weft raw materials are interwoven into plain weaves, and relaxation heat treatment is performed to prepare the wrinkled fabric; and the twisting directions of the wrinkled warps and the wrinkled wefts are opposite. A preparation process of the crescent-shaped composite fibers comprises the steps of in a process of preparing circular parallel composite fibers from PET and PTT according to anFDY process, changing spinneret orifices in a spinneret plate to be in the crescent shape from the circular shape, performing cooling by cross air blow, and controlling the arrangement of the spinneret orifices to meet a certain condition, thereby preparing the crescent-shaped composite fibers. When the parallel composite fibers are prepared, a PET melt and a PTT melt are distributed and then areextruded from the spinneret orifice m and the spinneret orifice n in the same spinneret plate; the spinneret orifice m and the spinneret orifice n are crescent-shaped spinneret orifices; and the contact surfaces of the PET melt and the PTT melt which flow in guide holes of the corresponding spinneret orifices are parallel to each other. The wrinkled fabric stable in quality and easy to process isprepared by adopting the simple method.

Description

technical field [0001] The invention belongs to the technical field of textile fabrics and relates to a preparation method of wrinkled fabrics. Background technique [0002] Chiffon fabric is a very light and thin chemical fiber fabric, suitable for women's summer clothes, and it feels a little frizzy; generally it can be divided into silk chiffon and imitation silk chiffon. Fabrics vary greatly. The most common chiffon fabric is made of polyester filaments, because the chiffon made of polyester filaments is crisp, wear-resistant and can also be blended with other fiber materials to give chiffon more performance. , such as the use of spandex blending, the chiffon fabric has a certain degree of elasticity. When spandex is used to weave elastic chiffon, spandex will cause the molecular chains in the spandex molecular chain to break or slip during heat treatment and washing. The strength and elasticity of spandex Response decreases; and in the weaving, pre-treatment, printing ...
