Abstract

The invention discloses a method for preparing a perdurable hydrophilic polyether modified amino-polysiloxane softener. The method is characterized by comprising the following steps: octamethylcy-clotetrasiloxane and amino silane coupling agents with different structures are used as raw materials; with a bulk polymerization method, under the analysis of an alkali catalyst, firstly, an amino organic polysiloxane softener with high ammonia value is generated through ring-opening polymerization; and secondly, on the basis of the amino organic polysiloxane softener, amidogen is subjected to etherifying modification, thereby synthesizing the hydrophilic polyether modified amino-polysiloxane softener with good hand feeling and hydrophilic property. The prepared softener keeps the hydrophilic property and simultaneously improves the softness of hydrophilic silicon oil so that the hand feeling of textile can reach the hand feeling of the prior linearity amino silicon oil after the textile is treated by the softener and the treated textile can keep the hydrophilic property permanently.

Description

technical field

[0001] The invention relates to a preparation method of durable hydrophilic polyether modified aminopolysiloxane softener. Background technique

[0002] The fabric softener made of silicone is a kind of softener with wide application, good performance and outstanding effect in textile. Among them, amino-functional polyorganosiloxane is one of the fastest-growing products in silicone softeners. Because it leads to the "inner softness" of the fiber, it is often called "advanced softening agent" and "king of softeners". It can be widely used in the soft finishing of various textiles. It can endow fabrics with unique properties such as smoothness, softness, fullness, crispness, and drape. And the finished fabric also has good washability, and is very popular and loved by people. However, the aminopolysiloxane softener widely used in the industry can endow the fabric with super softness, elasticity and washability, but its strong hydrophobicity seriously affect...
