Comb-shaped associative polyurethane composite modified organic silicon softener emulsion and preparation method thereof

Abstract

The invention relates to the field of polyurethane modified resin type organic silicon softener emulsion for finishing hand feeling styles of various textiles, and discloses comb-shaped associative polyurethane composite modified organic silicon softener emulsion and a preparation method thereof. The method comprises the following steps: preparing raw materials; performing prepolymerization; and carrying out chain extension and mixing emulsification. The softener emulsion disclosed by the invention is novel in structure and remarkable in effect. Various macromolecules in the emulsion can be effectively associated with each other, and blending modification of a traditional organic silicon softener is realized on textile fibers in a molecular blending manner. The self-made polyurethane modified polysiloxane polymer main chain has better extensibility, and polysiloxane long chains and polyether long chains are distributed in the side direction of the self-made polyurethane modified polysiloxane polymer main chain in an echelon manner; compared with a traditional amino modified organic silicon softener, the product provided by the invention can endow various textiles with obviously better hydrophilicity and elastic hand feeling; and the product is low in emulsifier content, safe, environmentally friendly and convenient to use, and has a good market prospect.

Description

technical field

[0001] The invention relates to the field of polyurethane-modified resin-type silicone softener emulsions for finishing various types of textiles, in particular to a comb-like association type polyurethane compound-modified silicone softener emulsion and a preparation method thereof. Background technique

[0002] In the past 10 years, as the most widely used, largest and most diverse textile chemical in textile printing and dyeing, silicone softeners have encountered development bottlenecks in terms of polymerization monomers, preparation technology, and style characteristics. In order to seek breakthroughs, relevant scientific and technical personnel are constantly trying to introduce non-silicon polymer materials with excellent properties into the structure or formulation system of silicone softeners, in order to obtain new or rich softeners such as hydrophilic, high-elasticity, richness, fineness, and softness. Variety of textile characteristic styles. In...
