Abstract

The invention relates to a preparation method of a coral velvet fabric. According to the preparation method, plush grey cloth is manufactured by weaving special-shaped semi-dull polyester drawn yarn as a raw material of wool yarn and polyester FDY yarn as a raw material of ground yarn, and then the coral velvet fabric is obtained through presetting, soft finish, fluff opening, napping, after-finish and resetting, wherein the wool yarn obtained by carrying out heat treatment and twisting on the special-shaped semi-dull polyester drawn yarn; a preparation process for the special-shaped semi-dullpolyester drawn yarn comprises the following steps of cooling through ring blowing after a PET melt is extruded from trilobal spinneret holes in a spinneret plate, and preparing the special-shaped semi-dull polyester drawn yarn according to an FDY process, wherein three leaves of each trilobal spinneret hole have the same length and different widths, the trilobal spinneret holes are distributed in a concentric circle, the center line of the narrowest leaf passes through the center of the circle and the pointing is away from the center of the circle. The preparation method disclosed by the invention is easy to operate, fluff of the prepared coral velvet fabric is fluffy, full, soft in hand feeling and good in warmth retention property.

Description

technical field [0001] The invention belongs to the technical field of textiles and relates to a method for preparing a coral fleece fabric. Background technique [0002] Coral fleece is a coral-like textile fabric with colorful colors and good coverage. It has fine texture, soft hand feeling, no pilling, not easy to shed, and beautiful appearance. In view of the obvious advantages of coral fleece, the demand for coral fleece products is on the rise, and the application fields are becoming more and more extensive. For example, gloves, nightgowns, fashion scarves, bath skirts, bathrobes, blankets, slippers, etc. are common in the market. Many products are made of coral. Cashmere is the raw material. This is due to its fine texture, no lint, no pilling, excellent water absorption performance, and beautiful appearance. The coral fleece fabric has a high fiber density, is coral-like, and has a soft body like coral. [0003] The coral fleece of the prior art has fine fineness, ...
