Abstract

The invention discloses a anti- storage yellowing agent for nylon and a preparation method of the anti- storage yellowing agent. The anti- storage yellowing agent comprises the following components bymass percent: 20-40% of linear alkyl benzenesulphonate, 10-25% of hydramine compound, 10-20% of an alcohol cosolvent, 1-3% of an anionic surfactant, 2-5% of a nonionic surfactant, 0.05-0.1% of a preservative and the balance of deionized water. The linear alkyl benzenesulphonate and the hydramine compound are combined to be taken as the raw materials, the compound synergetic effect of the raw materials is achieved while the effects of the linear alkyl benzenesulphonate and the hydramine compound are produced, and the anti- storage yellowing agent has an excellent anti-yellowing effect. The phenolic yellowing in the processes of storage, transportation and use of a nylon fiber product is prevented, the quality and the value of the nylon fiber product are improved, the raw materials meet theenvironmental requirement, belong to the environment-friendly products, are non-toxic, harmless and non-irritant, are environmentally friendly, and are pollution-free, the raw materials are basicallyuniversal raw materials, so that the pressure of the material inventory of a company is alleviated, and the production cost of the product is lowered.

Description

technical field [0001] The invention relates to the technical field of textile auxiliaries, in particular to an anti-storage yellowing agent for nylon and a preparation method thereof. Background technique [0002] Nylon fiber is favored by more and more consumers because of its good wear resistance and resilience, and it can be dyed into very bright colors. Nylon fibers can be woven into cloth, lace, elastic bands, belts, etc., and are widely used in outerwear, underwear, swimsuits, sportswear, luggage belts, etc., and white, light, and bright colors are the mainstream colors of these nylon fiber materials. Nylon fibers are often added with BHT (2,6-di-tert-butyl p-cresol) in the production process to prevent photoaging during storage and use, and BHT (2 , 6-di-tert-butyl-p-cresol), these BHT (2,6-di-tert-butyl-p-cresol) chemically react with nitrogen oxides (NOx) in the air, thereby producing yellowing. Nylon fiber products with yellowing will seriously affect the appear...
