Problems solved by technology

At present, the nylon fiber products that appear on the market, when they are prepared, the natural antibacterial active ingredients are easily damaged by high temperature during the nylon spinning process, resulting in a large loss. Secondly, cocoa active molecule epicatechin is used as a biomodified material in nylon fiber. It is easy to accumulate during processing, and the original nylon fiber products cannot solve the oxidation resistance and antibacterial properties of nylon fabrics during preparation, with low bonding stability, poor heat resistance, and easy yellowing
[0003] Moreover, the thermal weight loss temperature of the masterbatch cannot be improved after the original nylon fiber is prepared. The yellowing level cannot meet the requirements for use, and the finished nylon fiber loses its additional functions after being washed many times.

Description

technical field [0001] The invention relates to the technical field of fiber products, in particular to a method for preparing nylon macrobiological fibers containing cocoa active ingredients. Background technique [0002] Nylon, scientific name polyamide fiber, commonly known as nylon (Nylon), English name Polyamide (PA), high strength, good wear resistance, good resilience, can be purely spun or blended for various clothing and knitwear, it is the main molecule A general term for thermoplastic resins containing repeating amide groups—[NHCO]—in the chain. The application of nylon is closely related to the actual production and life. With the great enrichment of modern material life, health is the eternal development theme. As people pay more attention to their own health, the development of healthy fiber textiles has become the general trend. At present, the nylon fiber products that appear on the market, when they are prepared, the natural antibacterial active ingredients...
