Embodiment 1

[0039] The dyeing method of fine-denier acrylic top includes the following steps:

[0040] 1) Add 1 to 2 parts by weight of ethylenediamine di-o-hydroxyphenyl sodium acetate, 0.8 parts by weight of urea, 3.6 parts by weight of hydroxypropyl methylcellulose, and 1.3 parts by weight of N-vinylpyrrolidone / propylene into the dye vat. Amide copolymer and 30 parts by weight of vegetable dyes are put into 100 parts by weight of deionized water in sequence, stir evenly, and heat to 45°C;

[0041] 2) Add 2.9 parts by weight of 2-acrylamide-2-methylpropane sulfonic acid, 0.8 parts by weight of pancreatic bleach T, 1.3 parts by weight of hexamethoxymethyl tripolyhydroamine, and 4.2 parts by weight of maleic acid in sequence, and continue to stir until Mix well and heat to 60℃;

[0042] 3) Soak the top in the dyeing vat for 50 minutes;

[0043] 4) Dry the soaked top at 85°C;

[0044] 5) Dip the dried wool top into clean water and rinse for 50 minutes;

[0045] 6) Take out the rinsed top and let it...

Embodiment 2

[0047] The dyeing method of fine-denier acrylic top includes the following steps:

[0048] 1) Add 1 part by weight of ethylenediamine di-o-hydroxyphenyl sodium acetate, 0.8 parts by weight of urea, 3.6 parts by weight of hydroxypropyl methylcellulose, and 1.3 parts by weight of N-vinylpyrrolidone / acrylamide in the dye vat. Put 30 parts by weight of vegetable dye into 100 parts by weight of deionized water in turn, stir evenly, and heat to 45°C;

[0049] 2) Add 2.9 parts by weight of 2-acrylamide-2-methylpropanesulfonic acid, 0.8 parts by weight of pancreatic bleach T, 1.3 parts by weight of hexamethoxymethyl tripolyhydroamine, and 4.2 parts by weight of maleic acid in sequence, and continue to stir until Mix well and heat to 60℃;

[0050] 3) Soak the top in the dyeing vat for 50 minutes;

Abstract

The invention discloses a dyeing method of fine denier acrylic fiber top, comprising the following steps: 1) successively adding EDDHA-Na, urea, hydroxypropyl methyl cellulose, a N-Vinyl-2-pyrrolidone / acrylamide copolymer and vegetable dye into a dye vat and successively pouring deionized water, uniformly stirring and heating to 45 DEG C; 2) successively pouring 2-acrylamido-2-methyl propane sulfonic acid, Igepon T, hexakis methoxymethyl melamine and maleate, continuously stirring until the materials are fully and uniformly mixed, and heating to 60 DEG C; 3) immersing the top in the dye vat for 50 min; 4) drying the immersed top at 85 DEG C; 5) immersing the dried top in clear water and rinsing for 50 min; and 6) taking the rinsed top out of the clear water and naturally airing. The top dyed by the above method has excellent color fastness and has good dyeing uniformity and has no dyeing defect.

Description

Technical field [0001] The invention relates to a dyeing method of fine-denier acrylic fiber tops. Background technique [0002] In the existing method for dyeing fine-denier acrylic fiber tops, the color fastness of the dyed tops is not high, the dyeing uniformity is not good, and the dyeing is easy to produce. Summary of the invention [0003] The purpose of the present invention is to provide a method for dyeing fine-denier acrylic tops, the tops after dyeing have excellent light fastness, washing fastness, dry cleaning color fastness, rubbing color fastness, perspiration color fastness, Color fastness to water stains, color fastness to chlorine bleaching, non-chlorine bleaching color fastness, and good dyeing uniformity, colorless flowers. [0004] In order to achieve the above-mentioned objective, the technical scheme of the present invention is to design a dyeing method of fine-denier acrylic fiber top, which includes the following steps: [0005] 1) Add 1 to 2 parts by weight...
