Abstract

The invention discloses a dyeing method of stretched wool tops. The dyeing method comprises the following steps of: 1) adding sodium glycinate, isobornyl 2-methyl-2-propenoate, N-methyl-2-pyrrolidone, diphenyl ether tetracarboxylic acid dianhydride and plant dyes into a dye vat in sequence, evenly stirring, and heating to 45DEG C; 2) then, adding methacryloyloxyethyl trimethyl ammonium chloride, alcohol alkoxylate, dibutyl phthalate and iminodiacetic acid in sequence, continuously stirring until mixture is fully and evenly mixed, and heating to 60DEG C; 3) dipping the wood tops into the dye vat for 50 minutes; 4) drying the dipped wool tops at the temperature of 85DEG C; 5) dipping the dried wool tops in clean water to be rinsed for 50 minutes; 6) taking out the rinsed wool tops, and naturally drying. The dyed wool tops have the advantages of excellent colour fastness, good dyeing evenness and no color tone.

Description

technical field

[0001] The invention relates to a method for dyeing stretched wool tops. Background technique

[0002] In the existing dyeing method for stretched wool tops, the color fastness of the dyed wool tops is not high, the dyeing uniformity is not good, and colored flowers are easy to occur. Contents of the invention

[0003] The object of the present invention is to provide a dyeing method for stretched wool tops, the dyed tops have excellent color fastness to sunlight, color fastness to washing, color fastness to dry cleaning, color fastness to rubbing, color fastness to perspiration, Color fastness to water stains, 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 dyeing method for stretching wool tops, comprising the steps of:

[0005] 1) Add 1 to 2 parts by weight of sodium...
