Problems solved by technology

[0003] The fabrics treated with traditional amino-modified silicone oils have good softness, smoothness, elasticity, and are comfortable to the touch and washable. However, the fabrics treated with them, especially chemical fibers and blended fabrics, have poor hygroscopicity, are stuffy to wear, and have greatly improved wearability. Reduced, the fabric is prone to yellowing, and the phenomenon of sticking to rollers and cylinders occurs during processing. It is not resistant to high shear and has poor compatibility. The phenomenon of "emulsification and floating oil" often occurs during storage, transportation and application.

Abstract

The invention provides terpolymer block hydrophilic amino silicone oil and a preparation method and application thereof. The terpolymer block hydrophilic amino silicone oil is prepared by: reflux-reacting epoxy-terminated polyether silicone oil, amino-terminated polyether and isopropanol at 80-83 DEG C for 8-10 hours, adding a quaternization reagent for modifying, and distilling a modified product under reduced pressure. The terpolymer block hydrophilic amino silicone oil, as a chemical fiber fabric softener, can improve handle characteristics of bulkiness, softness and smoothness to chemical fiber fabric, is good in permeability and can go hydrophilic instantly on nylon fabric; the terpolymer block hydrophilic amino silicone oil has low influence on fabric yellowing and discoloration; the terpolymer block hydrophilic amino silicone oil has excellent chemical stability in resistance to acids, alkalis and salts, has good compounding stability with the aids such as a brightener, saves cost for customers in terms of energy conservation and emission reduction, and provides conveniences.

Description

Technical field [0001] The present invention relates to modified silicone oil technology, in particular to a method for preparing ternary copolymer block hydrophilic amino silicone oil, the ternary copolymer block hydrophilic amino silicone oil prepared by the method, and the ternary copolymer block Application of hydrophilic amino silicone oil as softener for chemical fiber fabrics. Background technique [0002] Since the 1960s, silicone softeners have gone through three stages of development. From the first generation of dimethyl silicone and hydroxyl modified silicone, to the second generation of epoxy modified silicone, polyether modified silicone, to the third generation of amino modified silicone. [0003] Fabrics treated with traditional amino-modified silicone oil have good softness, smoothness, elasticity, comfortable feel and washability. However, fabrics treated with it, especially chemical fiber and blended fabrics, have poor hygroscopicity, are stuffy to wear, ...
