Abstract

The invention relates to a modified chinlon fiber, a preparation method and application. Even dispersion of graphene particles in a chinlon base material is achieved through a physical method, the process is simple, no dispersing agent is needed, and industrial production is easy. Graphene, especially biomass graphene is introduced into chinlon, so that the modified chinlon fiber has a low-temperature far infrared function, and the far infrared normal emissivity of the modified chinlon fiber is 0.85 or above. The antibacterial property of the modified chinlon fiber is 90% or above, and the mechanical strength and breathability are excellent.

Description

technical field [0001] The invention belongs to the field of modification and preparation of nylon, and in particular relates to a modified nylon fiber, a preparation method and an application. Background technique [0002] Nylon, that is, polyamide fiber, commonly known as nylon (Nylon), the English name Polyamide (referred to as PA), the density is about 1.15g / cm 3 , is a general term for thermoplastic resins containing repeating amide groups -NHCO- on the main chain of the molecule, including aliphatic PA, aliphatic-aromatic PA and aromatic PA. Among them, aliphatic PA has many varieties, large output, and wide application. Its name depends on the specific number of carbon atoms in the synthetic monomer. [0003] The most prominent advantage of nylon is that its wear resistance is higher than that of all other fibers, 10 times higher than cotton and 20 times higher than wool. Adding some nylon to blended fabrics can greatly improve its wear resistance; when stretched Wh...
