Problems solved by technology

This oxidation will cause the sulfur dye particles to detach from the fabric fibers and rearrange on the fiber surface, seriously affecting its coloring effect on the fibers
Second, although the linear block amino-modified silicone oil has hydrophilic or semi-hydrophilic properties, when used with sulfur dyes, the sulfuric acid generated after the oxidation reaction will destroy the silicone oil film attached to the fabric fiber after finishing, and the silicone oil It may even decompose in a strong acidic environment, which will greatly reduce the hydrophilic property of the silicone oil itself, and make the fabric feel hard and rough

Abstract

The invention discloses durable hydrophilic silicone oil which is characterized that the silicone oil comprises side chain-amino-terminated silicane with a general formula A and single-ended polyether epoxy with a general formula B, the mole ratio of the side chain-amino-terminated silicane to the single-ended polyether epoxy is 1:(4-8), the components react under the alkaline environment to obtain a structural formula which is as shown in the specification, wherein x is 0-10, y is 0-10, z is 10-200, m is 5-20, R1 is one of -H, -CH3-, -CH2CH2- and -CH2CH3, and R2 is one of -CH3, -OCH3, -CH2CH3, -OCH2CH3 and -CH2CH(OH)CH3. The durable hydrophilic silicone oil can give smooth and soft hand feeling for fabrics, is high in chemical stability and has self-emulsifying function, so that the fabrics can have continuous hydrophilic properties.

Description

technical field [0001] The invention relates to the field of fabric dyeing and finishing auxiliaries, in particular to a durable hydrophilic silicone oil capable of endowing fabrics with continuous hydrophilic properties and a preparation method thereof. Background technique [0002] At present, amino-modified silicone oil is widely used in the fields of textile finishing and textile dyeing and finishing because of its good chemical reactivity, strong two-phase lubricity and compatibility. Amino-modified silicone oil mainly includes side-chain amino-modified silicone oil and straight-chain block amino-modified silicone oil. Straight-chain block amino-modified silicone oil has strong group linking ability, and most of them are hydrophilic or semi-hydrophilic. sex aids. During the dyeing and finishing process, linear block amino-modified silicone oil can not only spread on the surface of fabric fibers, but also penetrate into the tiny gaps inside the fabric with water molecul...
