Embodiment 1

[0032] (1) Fabric type: nylon matte weft-knitted plain weave (40D / 34F, 120g / m 2 )

[0033] (2) The process flow is as follows:

[0034] Preparation of carboxymethylated fatty amine polyoxyethylene ether: Add 0.1 mol of fatty amine polyoxyethylene ether (AC1803), 0.12 mol of chloroacetic acid, and 0.24 mol of sodium hydroxide in the reaction kettle, and react at a temperature of 80°C for 4 After one hour, the temperature was lowered to 40°C; an equal volume of ethanol was added to the reaction mixture, the white precipitate was filtered off, the ethanol was evaporated under reduced pressure at 40°C, and the milky yellow paste obtained was the carboxymethylated fatty amine polyoxygen vinyl ether.

[0035] Compounding of anti-fixation stain agent: by mass percent, carboxymethylated fatty amine polyoxyethylene ether 15%, chelating dispersant (sodium citrate 2%, low molecular weight maleic acid-acrylic acid copolymer 2%) %), 0.05% of organic silicon defoamer, and the balance of ...

[0038] (1) Fabric type: nylon matte weft-knitted plain weave (70D / 34F, 150g / m 2 )

[0039] (2) The process flow is as follows:

[0040] Preparation of carboxymethylated fatty amine polyoxyethylene ether: Add 0.1 mol of fatty amine polyoxyethylene ether (AC1803), 0.24 mol of chloroacetic acid, and 0.48 mol of sodium hydroxide in the reaction kettle, and react at 100°C for 2 After one hour, the temperature was lowered to 40°C; an equal volume of ethanol was added to the reaction mixture, the white precipitate was filtered off, the ethanol was evaporated under reduced pressure at 40°C, and the milky yellow paste obtained was the carboxymethylated fatty amine polyoxygen vinyl ether.

[0041]Compounding of anti-spotting agent: by mass percentage, 30% of carboxymethylated fatty amine polyoxyethylene ether, chelating dispersant (4% of sodium tartrate, 4% of low molecular weight sodium polyacrylate), organic silicon 0.1% of defoaming agent and water as the balance, compounded to fo...

Embodiment 3

[0044] (1) Fabric type: Nylon and nylon (70D / 30F×70D / 30F, 190T)

[0045] (2) The process flow is as follows:

[0046] Preparation of carboxymethylated fatty amine polyoxyethylene ether: Add 0.1 mol of fatty amine polyoxyethylene ether (AC1807), 0.16 mol of chloroacetic acid, and 0.32 mol of sodium hydroxide in the reaction kettle, and react at a temperature of 90°C for 3 After one hour, the temperature was lowered to 40°C; an equal volume of ethanol was added to the reaction mixture, the white precipitate was filtered off, the ethanol was evaporated under reduced pressure at 40°C, and the milky yellow paste obtained was the carboxymethylated fatty amine polyoxygen vinyl ether.

[0047] Compounding of anti-spotting agent: by mass percentage, 20% of carboxymethylated fatty amine polyoxyethylene ether, chelating dispersant (3% of iminodiacetic acid, 3% of polyaspartic acid), organic 0.1% of silicon defoaming agent and water as the balance, compounded to form nylon dyeing anti-f...

Abstract

The invention provides a nylon dyeing anti-spot fixation agent and an application method thereof. The anti-fixation and spotting agent for nylon dyeing provided by the invention comprises the following components: 15-30% of carboxymethylated fatty amine polyoxyethylene ether, 4-8% of chelating dispersant, 0.05-0.1% of silicone defoamer, The balance is water. Nylon fabrics treated with the nylon dyeing anti-fixation stain agent according to the technical solution of the present invention have the remarkable characteristics of thorough spot removal, short technological process, no influence on shade, high color fastness to wet treatment, and favorable clean production.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a nylon dyeing anti-spot fixation agent and an application method thereof. Background technique [0002] Nylon fiber, also known as nylon, is a polymer fiber material obtained mainly from hexamethylenediamine and adipic acid, aminocaproic acid or caprolactam through polycondensation reaction. It has the characteristics of high strength, abrasion resistance and good resilience. With its excellent wear resistance and light and thin texture, nylon fabric has become the best choice for sportswear, swimming suits, bodybuilding suits, down jackets, and mountaineering suits. In addition, nylon fiber is also widely used in the manufacture of industrial products such as cords, transmission belts, hoses, ropes, fishing nets, tires, and parachutes. [0003] Because disperse dyes and reactive dyes have a lighter color on nylon fabrics, acid dyes are mainly used for dyein...
