Abstract

The invention provides a phenol yellow-resistant functional masterbatch, a preparation method thereof, a use thereof and a phenol yellow-resistant nylon. The phenolic yellow functional masterbatch comprises the following components by weight: 30 to 70 parts of polyamide, 5 to 15 parts of silicone raw rubber, and 5 to 15 parts of organic acid. The phenolic yellow functional masterbatch is preparedby mixing the components of the formulation amount and then extruding it by an extruder. The phenolic yellow functional masterbatch provided by the invention can be used for phenol yellow modificationof polyamide, can be directly added to the polyamide, and can be simply mechanically mixed, thereby avoiding cumbersome modification by using phenol yellow-resistant agent. The post-treatment process; when the addition amount is 2wt%, the anti-phenol yellowing index of the nylon can reach 4, and the effect is long-lasting.

Description

technical field [0001] The invention belongs to the technical field of polymer fabrics, and in particular relates to a phenol yellow-resistant functional masterbatch, its preparation method, application and phenol yellow-resistant nylon. Background technique [0002] Fiber is widely used in textiles and processed into various garments because of its good wear resistance, fatigue resistance and resilience. Nylon is an important variety of synthetic fibers, belonging to nylon fibers, and its main component is polyamide (PA). The fabric made of nylon has the advantages of high strength, wear resistance, good elasticity and good hygroscopicity. [0003] Yellowing is an ever-present problem in textiles, seriously affecting the appearance. The yellowing phenomena of textiles mainly include phenol yellowing, heat yellowing, ultraviolet yellowing, fluorescent whitening agent yellowing, softener yellowing and oily yellowing. Among them, phenol yellowing is a yellowing phenomenon t...
