Embodiment 1

[0038] A kind of preparation method of crystal velvet fabric, its process is as follows:

[0039] (1) The preparation method of PBT fiber for crystal velvet is: PBT melt (intrinsic viscosity is 1.16dL / g) is extruded from the spinneret holes on the composite spinneret and cooled by ring blowing; wherein, the composite spinneret At the same time, there are three-lobed spinneret holes and triangular spinneret holes with a quantity ratio of 71:29. All the spinneret holes are distributed in concentric circles, and the trilobal spinneret holes are located on the outermost circle;

[0040] The ratio of the length of the three lobes of the same three-lobed spinneret hole is 1.0:1.5:2.1 and the lengths of the two long lobes are different. The corresponding ratio of the width of the three lobes is 1.5:1:1.5, and the ratio of the length to the width of the shortest lobe is 3:1, the angle between the centerlines of two adjacent leaves is 120°; the shape and size of the three leaves of dif...

Abstract

The invention relates to a preparation method of a crystal velvet fabric. The preparation method comprises the following steps of firstly, preparing PBT fibers for crystal velvet, namely, extruding aPBT melt from a spinneret hole in a composite spinneret plate, then ring blowing cooling is adopted, and preparing an FDY filament according to an FDY process to obtain the PBT fiber for the crystal velvet, wherein the composite spinneret plate is provided with a trilobe-shaped spinneret hole and a triangular spinneret hole at the same time; and taking a PBT fiber yarn for the crystal velvet as awarp yarn, and taking a PET fiber yarn as a weft yarn to perform interweaving to form a grey cloth, and sequentially carrying out drawing, pre-forming, dyeing, softening agent treatment, shearing andshaping to prepare the crystal velvet fabric, wherein finally, in the crystal velvet fabric, the crimp contraction rate of the PBT fiber for the crystal velvet is 31-34%, and the shrinkage elastic recovery rate is 79-84%; and the stiffness of the crystal velvet fabric is 4.24-5.46 / cm, the thermal resistance is 0.38-0.43K.m2 / W and the glossiness is 70-75%.

Description

technical field [0001] The invention belongs to the technical field of polyester fibers and relates to a method for preparing a crystal velvet fabric. Background technique [0002] Crystal velvet belongs to chemical fiber or finishing fabric, and its raw material is polyester, mainly pink. The crystal velvet fabric has dense fluff and diamond luster, and is now generally used for making women's clothing. But as far as its raw material is concerned, crystal velvet is not suitable for making clothes, because the velvet feel of the fabric itself is a bit thorny, unless it is used as clothing accessories. If it is used for making clothes, crystal velvet is suitable for winter casual wear , not suitable for making summer clothing or intimate clothing. [0003] The curly fiber has a soft hand feeling because of its small elastic modulus, and is widely used in close-fitting clothing. In crystal velvet fabrics, the introduction of curly fibers can improve its softness, but the gen...
