Abstract

The invention discloses a method for dyeing a PV pile fabric. The method comprises the following steps: (1) sequentially adding tea polyphenols, diethylenetriamine, ethylene glycol, a maleate-acrylate copolymer and vegetable dyes into a dye vat, successively adding deionized water into the dye vat, uniformly stirring, and heating the dye vat to the temperature of 45 DEG C; (2) then, sequentially adding ethylenediamine, iso-tridecanol polyoxyethylene ether, an N-vinyl pyrrolidone / acrylamide copolymer and 2-acrylic acid amide-2-methylpropanesulfonic acid into the dye vat, continuing stirring until the mixture is uniformly mixed thoroughly, and heating the dye vat to the temperature of 60 DEG C; (3) soaking the fabric in the dye vat for 45 minutes; (4) baking the soaked fabric at the temperature of 85 DEG C; (5) submerging the baked fabric in clean water, and rinsing for 45 minutes; (6) taking out the rinsed fabric, and naturally drying the fabric in the air. According to the method, the dyed fabric has excellent color fastness, is good in dyeing uniformity and is free of uneven dyeing.

Description

technical field [0001] The invention relates to a method for dyeing PV fleece fabrics. Background technique [0002] In the existing method for dyeing PV velvet fabrics, the color fastness of the dyed fabrics is not high, the dyeing uniformity is not good, and colored flowers are easy to occur. Contents of the invention [0003] The purpose of the present invention is to provide a method for dyeing PV velvet fabrics, the dyed fabric has excellent color fastness to rubbing, color fastness to washing, color fastness to dry cleaning, color fastness to sunlight, color fastness to perspiration, water fastness Color fastness to staining, color fastness to chlorine bleaching, color fastness to non-chlorine bleaching, and good dyeing uniformity, colorless flowers. [0004] In order to achieve the above object, the technical solution of the present invention is to design a kind of dyeing method of PV velvet fabric, comprising the steps: [0005] 1) Add 1 to 2 parts by weight of t...
