Abstract

The invention provides a nylon copolymer mixture, comprising multiple nylon copolymers and having a general formula (I) as shown in the description, wherein the definition of each parameter is recorded in details in the description. In respect to the total weight of the nylon copolymer mixture, the total content of terminal amino groups of the nylon copolymers is 10-40mEq / kg. The nylon copolymer mixture provided by the invention has a low content of the terminal amino groups, and low reactivity with a general stain, so that an understain effect can be achieved. In addition, the ether group of a polyether diamine oligomer provides good moisture absorbing and releasing properties, so that a fabric prepared from the nylon copolymer mixture has a significant cool sense effect. A preparation method of the nylon copolymer mixture and a nylon fiber containing the same are also disclosed by the invention.

Description

technical field [0001] The present invention relates to a nylon copolymer mixture, in particular to a nylon copolymer mixture with low content of terminal amine groups. Background technique [0002] Generally, nylon materials are mainly divided into nylon 66 and nylon 6. Nylon 66 is an alternating copolymer formed by the copolymerization of hexamethylenediamine and adipic acid, wherein the molar ratio of hexamethylenediamine and adipic acid is 1:1. Nylon 6 is a homopolymer formed by polymerization after hydrolysis and ring-opening of caprolactam, wherein one end of the ring-opening monomer formed by the hydrolysis of guinellactam is an amine group, and the other end is a carboxylic acid group. [0003] From the structures and synthesis methods of nylon 66 and nylon 6, it can be seen that the total content of terminal amino groups in nylon 66 and nylon 6 is about 50%. In addition, in the dyeing process of general nylon materials, because most of the dyes are acidic, they ar...
