Abstract

The invention relates to the technical field of softening agents, in particular to a ternary polymerization block polyether amino silicon oil softening agent. The structural formula is shown in the description, wherein R=-CH2CH2CH2, -CH3 or -CH2CH3, R'=C1-22 alkane, PO=OC3H6, EO=OC2H4, a and b are any integer from 5 to 24, c is any integer from 10 to 60, and n is any integer from 10 to 60. Yellowing, instability and hydrophobicity of ordinary amino silicon oil are overcome, fabric has excellent hand feeling, hydrophilia, washability and stability, and the softening agent is suitable for various kinds of pure cotton fabric, cotton-polyester blended fabric, wool and other kinds of fabric.

Description

technical field [0001] The invention relates to the technical field of softeners, in particular to a ternary copolymerized block polyether amino silicone oil softener and a preparation method thereof. Background technique [0002] Silicone is a kind of softener widely used in the textile industry. It can improve the fabric feel and is harmless to the body. It is very popular. However, silicone makes the fabric show a certain degree of hydrophobicity, which reduces the comfort and hygroscopicity of the fabric. At the same time, it is easy to cause yellowing, is sensitive to high temperature and high alkali, and is prone to oil spots and demulsification. Contents of the invention [0003] In view of the above defects, the present invention improves the hydrophilicity and stability of ammonia organosilicon, and proposes polysiloxane linear polymerization technology, that is, carries out block copolymerization of amino groups and polyether groups in the siloxane skeleton, and ...
