Abstract

The invention discloses a polypeptide-siloxane copolymer, which is characterized in that the polypeptide-siloxane copolymer has the general formula shown in the specification, wherein x=0-1000, y=0-10 and m=2-100; and R is selected from one or more of hydrogen, methyl, isopropyl, isobutyl, carboxymethyl, carboxyethyl and phenylpropyl. The polypeptide-siloxane copolymer is used as the finishing agent of the fabrics, not only can ensure the fabrics to have the effects of softness and smoothness, but also has good stability and quite good shear force, centrifugal force, electrolyte, hard water and other index values and has no adverse effects on the hue of the fabrics under high temperature.

Description

technical field The invention relates to a fabric softener and a preparation method thereof, more specifically to a polypeptide-siloxane copolymer used for textile treatment and a preparation method thereof. The invention belongs to the technical field of textile finishing auxiliaries. Background technique In the textile chemical industry, polyorganosiloxane is usually used to improve the performance of textiles, and is an important auxiliary agent for the post-treatment of natural and synthetic fiber fabrics. Linking corresponding functional groups to the siloxane molecular chain segment can have good hydrophilicity, hydrophobicity, antistatic properties, softness, smoothness, antibacterial properties, etc., especially amino-modified The finishing effect of polyorganosiloxane (amino silicone oil) is better. However, amino silicone oil has the disadvantages of easy yellowing and insufficient hydrophilicity, which will have adverse effects on the finished textiles. Polype...
