Abstract
The invention discloses a water-born polyurethane coating agent containing ultrafine down fibre-beta-cyclodextrin microspheres. According to the water-born polyurethane coating agent containing the ultrafine down fibre-beta-cyclodextrin microspheres, down fibres can be treated into glutaraldehyde grafted ultrafine fibres with high reactivity and high thermal stability; the glutaraldehyde grafted ultrafine fibres are dispersed into a mixed emulsion of beta-cyclodextrin; composite microspheres are obtained through homogenization treatment after a reaction is ended. The ultrafine down fibres can be effectively led into a polyurethane emulsion by the composite microspheres; meanwhile, the defect that the ultrafine down fibres easily regain moisture is overcome; a coating formed by the coating agent is breathable and moisture permeable, and is capable of keeping warm and deodorizing; the wearing experience of a textile can be effectively improved.
Description
Technical field
The present invention relates to fabric coating finishing agent technical field, particularly relate to a kind of Aqueous Polyurethane Coating Agent containing ultra-fine down fiber-beta-schardinger dextrin microballoon.
Background technology
Fabric coating finishing agent is called for short coating agent, is a kind of macromolecular compound film coating fabric face, in order to improve the style of fabric, feel and outward appearance etc., greatly improves the surcharge of textile.Aqueous Polyurethane Coating Agent is the environment-friendly coating agent that a class is important, it has elastic excellent, soft, the advantages such as wear-resisting solvent resistant, but its poisture-penetrability is poor, the dress having a strong impact on fabric is experienced, and production cost is high, along with the lifting of the market demand, research waterproof and breathable class environment-friendly polyurethane textile coating agent is particularly important." preparation of fibroin/Moisture-permeable Waterproof Polyurethane Coating and application thereof " literary composition utilizes fibroin to be modified polyurethane processing, effectively raise the moisture permeable effect of coating agent, but the hydrophobicity of fibroin is poor, along with the resistance to water of the raising coated film of fibroin mass fraction can be deteriorated, and the production cost of fibroin is higher, it is unfavorable for large-scale production.
China is eider down big producing country, annual production leads and bounds ahead of other countries, eider down is the natural protein material of the amino acid peptide chain structure of a kind of many groups, crude protein content accounts for more than the 80% of whole eider down, the fluffy softness of its structure, warmth retention property is remarkable, possess good hygroscopicity and biocompatibility, but the research and utilization in terms of its utilization of resources is still in the rough machined level of raw material, in addition to a small amount of warming packing material of conduct is for clothes and bedding, some is used for sports goods, handicraft and the reinforcing material of composite, major part is all by as offal treatment, cause the substantial amounts of wasting of resources.Eider down is superior to fibroin in terms of moisture-penetrable ventilated property and resistance to water, if can effectively be introduced in polyurethane coating agent by eider down, it will obtain the coating agent possessing excellent comprehensive performance, improves the economic worth of fabric.
Summary of the invention
