Abstract

The invention relates to a preparation method of a double-sided different-velvet fiber fabric. Cationic polyester fully-drawn yarns are adopted as velvet yarn raw materials, CDP FDYs are adopted as bottom yarn raw materials, the cationic polyester fully-drawn yarns and the CDP FDYs are subjected to beaming, warp knitting and slitting to prepare a gray fabric, and the gray fabric is subjected to napping, front ironing, back carding, shearing, first-time anti-pilling treatment, presetting, ironing, second-time anti-pilling treatment and setting to obtain the double-sided different-velvet fiber fabric, wherein a preparation process of the cationic polyester fully-drawn yarns comprises the steps of performing cooling by cross air blow after a CDP melt is extruded from trilobal spinneret holesin a spinneret plate, and preparing the FDYs according to an FDY process, namely, obtaining the cationic polyester fully-drawn yarns. The prepared double-sided different-velvet fiber fabric has the gram weight being 200-250 g / m<2>, the wicking height being 11. 6-12.7 cm, the thermal resistance being 0.40-0.43 K.m<2> / W, the fullness being 4.5-5.0 and the softness being 4.5-5.0.

Description

technical field [0001] The invention belongs to the technical field of polyester fibers and relates to a method for preparing a double-sided cashmere fiber fabric. Background technique [0002] In the preparation of double-sided cashmere fabrics, chemical fibers are generally used as raw materials. After weaving gray fabrics, they are made through processes such as napping, shearing, and napping. The prepared double-sided cashmere fabrics are used in many aspects, such as dust-free Wipes, home textiles, clothing, etc. Clothes made of double-sided cashmere fabrics are mostly for wearing in autumn and winter. The suede surface gives people a feeling of comfort, softness and warmth. However, because the raw material of double-sided cashmere is chemical fiber, it shows poor hygroscopicity. , The problem of insufficient warmth. [0003] Therefore, it is of great significance to develop a kind of double-sided cashmere fabric with a rich feel that can meet the needs of autumn and...
