Abstract

The invention discloses a high-elasticity heat-resistant chinlon 6 and a preparation method, and relates to the technical field of fiber product related technologies. According to preparation of the high-elasticity heat-resistant chinlon 6, organic layered aluminum phosphate is prepared and is added in caprolactam and plant fiber lignin; and due to the special lamellar structure of the layered organic aluminum phosphate, the prepared high-elasticity heat-resistant chinlon 6 is uniformly dispersed in a macromolecular matrix, caprolactam polymerization and uniform distribution can be implemented, a molecular skeleton is stable, and the stability of the chinlon 6 when a material is prepared from the chinlon 6 later is facilitated, for example, uniform dyeing, high temperature resisting, low temperature resisting, difficulty in deformation, reduction of water content, difficulty in dampness, high elasticity, thermal stability and the like are facilitated.

Description

Technical field [0001] The invention relates to the technical field of textiles, in particular to the technical field of nylon preparation, and more particularly to a high-elasticity and heat-resistant nylon 6 and a preparation method. Background technique [0002] Nylon is the trade name of polyamide fiber, also known as nylon, nylon (Nylon), or PA for short. Its basic constituent is an aliphatic polyamide connected by an amide bond—[NHCO]—, which contains repeats in the main chain of the molecule. The amide group-[NHCO]-is the general term for thermoplastic resins, including aliphatic PA, aliphatic-aromatic PA and aromatic PA. Among them, aliphatic PA has many varieties, large output and wide application, and its name is determined by the specific carbon number of the synthetic monomer. The molecular formula of Nylon 6 is -[NH(CH2)5CO]-n, which is soluble in phenol and hot concentrated sulfuric acid. It has excellent electrical insulation performance, good alkali resistance an...
