Problems solved by technology

This method is suitable for polyester fibers and polyamide fibers, but not for down fibers, because this method will destroy the bimolecular film on the surface of down fibers, affect its surface structure, thereby destroying its superhydrophobicity, and in To a certain extent, the excellent bulkiness of down is greatly reduced, which is not conducive to the application of down in various aspects

Abstract

The invention relates to a method for compounding functional nano particles on the surfaces of down feather fibers and belongs to the technical field of textile materials. According to the method provided by the invention, the functional nano particles are compounded on the surfaces of the down feather fibers by preparing a down feather fiber / sodium polystyrenesulfonate dispersed solution, preparing a functional nano particle solution and compounding the surfaces of the down feather fibers. The dispersed functional nano particles are firmly compounded on the surfaces of the down feather fibers by the effects of molecules layer upon layer through sodium polystyrenesulfonate, a sulfo group dispersing agent and the functional nano particles, so that the down feather fibers have various functions. The method for compounding the functional nano particles on the surfaces of the down feather fibers effectively utilizes a lot of waste down feather fibers, improves the additional value of the down feather fibers and explores applications of the down feather fibers in the other fields; furthermore, the whole process equipment is simple, the cost is low, pollution to the ecological environment is not caused and the application prospect is very great.

Description

technical field [0001] The invention relates to a method for compounding functional nanoparticles on the surface of down fibers, belonging to the technical field of textile materials. Background technique [0002] Down comes from the feathers of poultry. It is a natural protein material and is very rich in resources. Our country's annual output reaches more than 600,000 tons, accounting for 60% of the world's total output. It has a wide range of sources and low economic costs. Down is in the shape of a flower, with 60-150 down filaments, which are distributed radially outward with a node as the core, forming a three-dimensional spatial structure that is sparse on the outside and dense on the inside. The down silk has the characteristics of natural curl and softness, and the closer the distribution of the down silk to the core, the greater the density of the down silk. Therefore, the velvet filaments between the velvet and velvet are not cohesive, and are in a fluffy state. ...
