Problems solved by technology

Although polyether / epoxy silicone oil (CJF) can endow the finished fabric with excellent hydrophilicity, there are problems such as poor hand feeling and unsatisfactory washing resistance of the finished fabric, while epoxy polyether silicone oil and hydrophilic polyetheramine Alternately arranged linear copolymers can endow the finished fabric with excellent hydrophilicity and hand feeling, but the synthesized silicone oil has a single structure and cannot satisfy diversified hand feelings

Abstract

The invention relates to the field of textile assistants, and especially relates to a preparation method of side chain hydrophilically-modified block silicone oil for cotton. The side chain hydrophilically-modified block silicone oil is prepared by a reaction of side chain hydrogen-containing silicone oil, allyl epoxy polyether, amino-terminated polyethylene glycol, glycidyl polyhedral oligomericsilsesquioxane, isopropanol and the like. The modified monomer is glycidyl polyhedral oligomeric silsesquioxane with multiple functional groups, so that the prepared side chain hydrophilically-modified block silicone oil for cotton has a polyhedral oligomeric frame structure, and a finishing agent prepared from the side chain hydrophilically-modified block silicone oil for cotton can endow cottonfabrics with excellent hydrophilicity, yellowing resistance, thickness, stiffness, elasticity and washing resistance.

Description

technical field [0001] The invention relates to the field of textile auxiliaries, in particular to a preparation method of side chain hydrophilic modified block silicone oil for cotton. Background technique [0002] In recent years, the field of silicone oil has developed rapidly, and various functional silicone oils have sprung up, especially in terms of hydrophilic silicone oil. Traditional hydrophilic silicone oil is mainly divided into polyether / epoxy silicone oil (CJF), epoxy polyether silicone oil and hydrophilic polyether amine alternately arranged linear copolymers. Although polyether / epoxy silicone oil (CJF) can endow the finished fabric with excellent hydrophilicity, there are problems such as poor hand feeling and unsatisfactory washing resistance of the finished fabric, while epoxy polyether silicone oil and hydrophilic polyetheramine Alternately arranged linear copolymers can endow the finished fabric with excellent hydrophilicity and hand feeling, but the synt...
