Abstract

The invention relates to the field of textile finishing agents, particularly a super-soft / smooth block silicon oil and a preparation method thereof. The preparation method comprises the following steps: after mixing octamethylcyclotetrasiloxane and an amino coupling agent, reacting under the action of an alkaline catalyst to obtain a common side chain amino modified silicon oil intermediate A; reacting the prepared A with an amino-terminated polyether coupling agent under the action of an alkaline catalyst to obtain an amino-terminated polyether block and side chain amino modified silicon oil intermediate B; and carrying out polymerization reaction on the prepared B and epoxy-terminated polyether under the action of an organic solvent to finally obtain terpolymer block side chain amino-modified organic silicon oil. By introducing side chain amino group into the straight-chain terpolymer block silicon oil compound, the fabric finished by the compound has excellent soft, fluffy and smooth effects and excellent whiteness, and thus, the compound is suitable for super-soft / smooth finishing of cotton, cotton-chemical fiber blend fabrics and the like.

Description

technical field [0001] The invention relates to an ultra-soft and slippery block silicone oil and a preparation method thereof, which are mainly used for soft and smooth finishing in the post-finishing process of textiles. Background technique [0002] At present, softeners based on various amino-modified silicone oil emulsions are widely used in the finishing of textiles such as cotton, silk, wool and polyester. The finished fabrics are soft, smooth, beautiful, washable and comfortable to wear. characteristics. Such products are accepted by people. The shortcomings are mainly manifested in the hydrophobicity of the fabrics finished by it; the light-colored and white fabrics finished with it will show different degrees of yellowing after high-temperature baking, and many amino-modified silicone emulsions are stable. The performance is very poor, and the phenomenon of demulsification and floating oil often occurs during storage and application; during the use of padding, ro...
