[0012] Similarly, although the amino group and the polyether chain link of the polyether block hydrophilic modified amino silicone oil softener prepared by this method are all in the main chain structure of the softener molecule, its amino group is a secondary amino group structure and its content is relatively high. Low, so the adsorption capacity of the softener molecules to the fibers and the performanc

Description

technical field [0001] The present invention relates to the hydrophilic silicone softener used for improving the soft style hand feeling of cellulose fiber textiles, protein fiber textiles, polyester fiber textiles and cellulose fibers, protein fibers, polyester fiber blends and interwoven textiles, specifically The invention relates to a preparation method of a quaternary ammonium cationic polyurethane-based polyether block hydrophilic silicone softener microemulsion and a product thereof. Background technique [0002] At present, silicone polymer emulsions are often used in the soft style finishing of various textile products. In order to overcome the water repellency of finished textiles derived from the weak polarity of silicone polymer softener molecules, polyether-modified hydrophilic silicone polymer softener products are rapidly replacing traditional silicone softener products. Polyether-modified hydrophilic silicone softeners generally graft and block polyether cha...
