Abstract

The invention discloses an elastic polyester imitated natural silk textile fabric and a preparation method thereof. The preparation method comprises the following steps that polyester chips and montmorillonite are subjected to pre-crystallization drying; the polyester chips and the montmorillonite are mixed and put into a screw extruder to be melted to obtain a melt; the melt is guided into a rawmaterial box of a spinning machine, and spinning is conducted by adopting a three-leaf special-shaped hole; a three-leaf special-shaped silk is put on a drafting machine for drafting; modified polyester fiber and bamboo carbon fiber are subjected to twisting treatment, and through setting treatment and the warp and weft woven technology, gray fabric is obtained; the gray fabric is put in a refining solution; and the gray fabric is subjected to dyeing treatment, and the elastic polyester imitated natural silk textile fabric is obtained. The elastic polyester imitated natural silk textile fabricprepared by the invention is close to natural silk in the aspects of shape and hand feeding, high in spinnability and elasticity, good in moisture absorption and air permeability and easy to dye, inaddition, the preparation method is simple, the preparation technology is easy to operate, economic benefits are high, and the elastic polyester imitated natural silk textile fabric is suitable for wide production and popularization.

Description

technical field [0001] The invention relates to the technical field of textile fabrics, in particular to an elastic polyester imitation silk textile fabric and a preparation method thereof. Background technique [0002] Silk is the lightest, softest and thinnest natural fiber in nature. It has the characteristics of no cake, no stuffiness, no shrinkage, uniform and soft inner tube. It not only feels good, looks elegant, but also has good physical properties such as strength. Favorite apparel material. However, the area and output of sericulture are limited, the output of natural silk decreases sharply, and the cost increases day by day, which greatly limits the wide application of silk. [0003] Polyester fiber is the largest variety of synthetic fiber, and its output accounts for more than 80% of the total output of chemical fiber. It is widely used in clothing fabrics and other non-clothing fields. Polyester clothing is crisp and stylish to wear, but its surface is not h...
