Problems solved by technology

[0003] Although there are some commercial heat-resistant yellowing agent products used in the finishing of nylon, spandex and their blended fabrics on the market, such as Umidol PAT and Umidol UWP from Clariant, Switzerland, and Dr. TH. B? HME from Germany. Solpon SPDX, DM-2915 (B) of Guangdong Demei Chemical, TF-621 of Transfar Chemical, and HJW-AY SUPER of nylon high-temperature anti-yellowing agent of Shenzhen Hengxinwang Textile Chemicals Co., Ltd., etc., but none of these products The structure and composition of heat-resistant yellowing agents are given, and the price of these commercial heat-resistant yellowing agents is relatively high, which is not conducive to popularization and application in production
[0004] In the prior art, someone (CN101250812A) used a smoothing agent, an emulsifier, a cleaning agent, and an additive to form an anti-yellowing oil agent and achieved a good anti-yellowing effect, but this method was tried on polyester fabrics. Not suitable for nylon spandex

Embodiment 1

[0025] Embodiment 1: Anti-yellowing finishing of nylon 6 woven fabric.

[0026] Formula: urea 5g, sodium hypophosphite 6g, adipate dihydrazide 9g.

[0027] Finishing process: Weigh the raw materials of each component according to the formula, add water to prepare a solution with a concentration of 5g / L, and adjust the pH to 4.5~5 with citric acid. Pad the nylon fabric with the solution (residual rate of 55-60%, adjust the padding pressure to 0.34MPa), and dry the fabric at 95°C for 10 minutes.

Embodiment 2

[0028] Example 2: Anti-yellowing finishing of swimwear fabrics.

[0029] Formula: urea 5g, sodium hypophosphite 6g, adipate dihydrazide 9g.

[0030] Finishing process: Weigh the raw materials of each component according to the formula, add water to prepare a solution with a concentration of 5g / L, and adjust the pH to 4.5~5 with citric acid. Pad the swimsuit fabric with the solution (the excess rate is 55-60%, adjust the padding pressure to 0.34MPa), and dry the fabric at 95°C for 10 minutes.

Embodiment 3

[0031] Example 3: Anti-yellowing finishing of seamless underwear fabric.

[0032] Formula: urea 5g, sodium hypophosphite 6g, adipate dihydrazide 9g.

[0033] Finishing process: Weigh the raw materials of each component according to the formula, add water to prepare a solution with a concentration of 5g / L, and adjust the pH to 4.5~5 with acetic acid. Pad the nylon interlining with the solution (residual rate of 75-80%, adjust the padding pressure to 0.34MPa), and dry the fabric at 95°C for 10 minutes.

Abstract

The invention relates to a composite heat-yellow discolouration resistant finishing agent of chinlon, spandex and a blended fabric of the two. The composite heat-yellow discolouration resistant finishing agent mainly comprises a potentiating agent, a synergist and a main antioxidant. After the chinlon, the spandex and the blended fabric are treated by a solution of the composite heat-yellow discolouration resistant finishing agent, the yellow discolouration and colour change of the chinlon, the spandex and the blended fabric can be remarkably alleviated. The composite heat-yellow discolouration resistant finishing agent is low in cost, simple in treatment process and high in industrial application value.

Description

technical field [0001] The invention relates to a composite anti-yellowing finishing agent for nylon, spandex and its blended fabrics, in particular to a low-cost and easy-to-use finishing agent for improving heat setting, molded yellowing and color change of nylon, spandex and their blended fabrics Composite anti-yellowing finishing agent. Background technique [0002] Nylon, also known as polyamide fiber or nylon, has many amide groups in its molecular structure. Spandex is also called polyurethane fiber, and there are many carbamate groups in its molecular structure. Nylon and spandex have many excellent physical and mechanical properties and are widely used in textile and other industrial fields. However, nylon also has disadvantages such as poor heat resistance, easy yellowing and brittleness under light and heat. Especially during high-temperature processing, such as heat setting and compression molding, it is prone to yellowing and discoloration, which affects the ...
