Abstract

The invention discloses dyed acrylic fabric and a dyeing method thereof. The dyed acrylic fabric is prepared from acrylic fabric which is treated with a microbial modifier and then dyed with a naturalorganic dye, wherein the microbial modifier contains pseudomonas, Nocard and fusarium, and the natural organic dye is a vegetable dye or an animal dye. According to the dyed acrylic fabric, active groups obtained by microbial biochemical reaction on the acrylic fabric can be in bonding joint with the natural organic dye, so that the acrylic fabric has the advantages of good dyeing effect and goodcolor fastness; the dyed acrylic fabric can be applied to every field of textiles and costumes.

Description

technical field [0001] The invention relates to the technical field of textile products, in particular to a dyed acrylic fabric and a dyeing method thereof. Background technique [0002] Acrylic fabric is a fabric woven from polyacrylonitrile or acrylonitrile copolymer fibers with a mass percentage of acrylonitrile greater than 85%. Among them, the performance of acrylic fabric is very similar to that of wool, with good elasticity, acid resistance and oxidation resistance, and light resistance. , Antibacterial, not afraid of moths, but when used in textiles and clothing, there are defects such as weak water absorption, easy to generate static electricity, poor dyeing performance, poor wear resistance, etc., which seriously limit the application of acrylic fabrics in textiles and clothing. In order to overcome the above-mentioned defects of acrylic fiber fabrics and make them have better wearing properties, people have carried out many modifications to acrylic fiber fabrics. ...
