Abstract

The invention discloses a chinlon 6 section for a bromochlorodifluoromethane (BCF) carpet yarn and a preparation method thereof. The chinlon 6 section is prepared from the following raw materials in percentage by weight: 99-100% of caprolactam, 0.02-1% of additive A, 0.02-1% of additive B, 0.05-0.6% of modifierand 0-0.5% of delustering agent; and the sum of the weight percents of all components is 100%. The preparation method of the section comprises the following steps: 1) preparation of solution of the additive A; 2) preparation of solution of the additive B; 3) preparation of modifier solution; 4) preparation of delustering agent dispersion liquid; 5) continuous polymerization; 6) extraction; and 7) drying. Compared with of the traditional section, the chinlon 6 section manufactured by the invention has the advantages the heat stability, the light stability and the dyeability are improved; the preparation step in a spinning process is reduced; the spinning stability, and the dyeability and the light stability of the BCF carpet yarn are improved; and the chinlon 6 section is especially suitable for production of the BCF carpet yarn.

Description

Technical field

[0001] The invention relates to a nylon 6 slice used for BCF carpet yarn and a preparation method thereof. Background technique

[0002] Nylon 6 is one of the earliest synthetic fibers to be industrialized. As early as 1942, FARBE in Germany built the first nylon 6 production line. For decades, the nylon 6 industry has experienced tremendous development. At present, nylon 6 is mainly used in four areas: textile filaments, industrial filaments, engineering plastics and BCF carpet filaments.

[0003] Carpets were almost all made of wool before the invention of synthetic fibers. This is due to its good resilience, but the wear resistance of wool is average. Because nylon 6 has good wear resistance, resilience and other performance characteristics, Compared with other synthetic fibers such as polypropylene and polyester, nylon BCF carpet yarn is often used to produce high-grade carpets.

[0004] At present, the method of using nylon 6BCF filament raw materials ...
