[0049] Example 1
[0050] A preparation method of wrinkled fabric, the steps are as follows:
[0051] (1) Preparation of crescent-shaped composite fibers: from PET (intrinsic viscosity of 0.53dL / g) and PTT (intrinsic viscosity of 1.2dL / g) with a mass ratio of 50:50, according to the FDY process and circular juxtaposed composite fibers (the The spinneret hole on the spinneret is changed from circular to crescent-shaped) to prepare crescent-shaped composite fibers; among them, when preparing side-by-side composite fibers, PET melt and PTT melt are distributed from the same spinneret. The spinneret hole m (crescent-shaped spinneret hole) and the spinneret hole n (crescent-shaped spinneret hole) are extruded;
[0052] The distribution means that the PTT melt is distributed through the distribution hole A, while the PET melt is distributed into the spinneret m through the distribution hole B, the PTT melt is distributed through the distribution hole C, and the PET melt is distribu...

[0067] A preparation method of wrinkled fabric, the steps are as follows:
[0068] (1) Preparation of crescent-shaped composite fibers: from PET (intrinsic viscosity of 0.52dL / g) and PTT (intrinsic viscosity of 1.1dL / g) with a mass ratio of 50:50, according to the FDY process and circular juxtaposed composite fibers (the The spinneret hole on the spinneret is changed from circular to crescent-shaped) to prepare crescent-shaped composite fibers; among them, when preparing side-by-side composite fibers, PET melt and PTT melt are distributed from the same spinneret. The spinneret hole m (crescent-shaped spinneret hole) and the spinneret hole n (crescent-shaped spinneret hole) are extruded;
[0069] The distribution means that the PTT melt is distributed through the distribution hole A, while the PET melt is distributed into the spinneret m through the distribution hole B, the PTT melt is distributed through the distribution hole C, and the PET melt is distribu...
