Problems solved by technology

However, if the white and light-colored fabrics that will undergo high-temperature treatment, such as heat setting and high-temperature compression molding, are not treated with anti-yellowing finishing, yellowing will easily occur, which will not only change the appearance, but also greatly reduce the service life.
Therefore, when the fiber is treated at high temperature (such as heat setting and compression molding), white and light-colored fabrics need anti-yellowing finishing. The disadvantages of the existing anti-yellowing agents are high formula cost and poor anti-yellowing performance

Embodiment 1

[0011] An anti-yellowing agent for nylon is composed of fatty alcohol polyoxyethylene ether AEO-7 15%, carbohydrazide 2.5wt%, propylene glycol methyl ether 10wt% and water 72.5wt%.

[0012] During preparation, the above-mentioned components are directly stirred and mixed in a container to obtain the finished product of the anti-yellowing agent.

Embodiment 2

[0014] An anti-yellowing agent for nylon, which consists of 10% Span-20, 5wt% carbohydrazide, 15wt% dipropylene glycol methyl ether and 70wt% water.

[0015] During preparation, the above-mentioned components are directly stirred and mixed in a container to obtain the finished product of the anti-yellowing agent.

Embodiment 3

[0017] An anti-yellowing agent for nylon is composed of Tween-60 12%, carbohydrazide 7wt%, dipropylene glycol methyl ether 10wt% and water 71wt%.

[0018] During preparation, the above-mentioned components are directly stirred and mixed in a container to obtain the finished product of the anti-yellowing agent.

[0019] Taking white nylon woven fabric as an example, the white nylon woven fabric is subjected to high temperature setting.

[0020] Sizing process: the anti-yellowing agent solution of 1-3 of the present embodiment (pressure 2kg / cm 2 , Liquid rate 50-60%), pre-baked in a heat setting machine at 100°C for 2 minutes and then set at 190°C for 60 seconds, and finally tested the whiteness of the white nylon fabric treated with anti-yellowing agent and untreated.

Abstract

The invention provides an anti-yellowing agent for nylon. The anti-yellowing agent is characterized by comprising, by weight, 10-20% of emulgator, 1-10% of carbohydrazide, 10-15% of an organic solvent and 55-79% of water. The anti-yellowing agent is low in formula cost, good in high-temperature anti-yellowing effect, capable of keeping whiteness and freshness of a fabric, user-friendly, environmentally friendly and wide in market prospect.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a formula of a high-temperature anti-yellowing agent for fibers (including fibers such as nylon and nylon elastic). Background technique [0002] Nylon has good wear resistance, fatigue resistance and resilience, and is widely used in stockings, elastic knitted outerwear, thin seamless underwear, high-end swimwear, sportswear and suit lining, etc., and is deeply loved by consumers. Nylon-containing white textiles and dyed textiles are used to be processed into various clothing, underwear, sportswear, swimsuits, etc., and are deeply loved by consumers. However, if the white and light-colored fabrics that will undergo high-temperature treatment, such as heat setting and high-temperature compression molding, are not treated with anti-yellowing finishing, yellowing will easily occur, which will not only change the appearance, but also greatly reduce the service ...
