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; ...

Embodiment 2

[0067] A preparation method of wrinkled fabric, the steps are as follows:

[0068] (1) Preparation of crescent-shaped composite fiber: PET (intrinsic viscosity is 0.52dL / g) and PTT (intrinsic viscosity is 1.1dL / g) with a mass ratio of 50:50 are juxtaposed by FDY process and circular composite fiber (will be 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;

[0069] 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 ...

Embodiment 3

[0084] A preparation method of wrinkled fabric, the steps are as follows:

[0085] (1) Preparation of crescent-shaped composite fiber: PET (intrinsic viscosity is 0.56dL / g) and PTT (intrinsic viscosity is 1.11dL / 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;

[0086] 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 invention relates to a preparation method of a wrinkled fabric. The crescent-shaped composite fiber is used as a crepe raw material, and the crescent-shaped composite fiber and cotton fiber are used as a crepe weft raw material, which is interwoven into a plain weave and then subjected to relaxation heat treatment to obtain a wrinkled fabric; The twist direction of the warp and crepe weft is opposite; the preparation process of the crescent-shaped composite fiber is as follows: in the process of preparing circular side-by-side composite fibers from PET and PTT according to the FDY process, the spinneret holes on the spinneret plate are changed from circular to Crescent shape, cooled by circular air blowing, and controlling the arrangement of spinneret holes to meet certain conditions, to obtain crescent-shaped composite fibers; when preparing side-by-side composite fibers, PET melt and PTT melt are distributed from the same spinneret The spinneret m and the spinneret n are extruded; the spinneret m and the spinneret n are crescent-shaped spinneret holes; the contact surface of PET melt and PTT melt flows in the guide holes of each spinneret hole parallel to each other. The invention adopts a simple method to prepare a wrinkled fabric with stable quality and easy processing.

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 ...
