Abstract

The invention discloses a mercerization penetrant for cellulose fiber mercerizing and terylene alkaline de-weighting technologies, and a preparation method thereof. The mercerization penetrant comprises 30-50wt% of octyl phosphate, 10-30wt% of JFC phosphate ester, 10-30wt% of an amphoteric polymer surfactant and 10-30wt% of alkyl glycoside. The alkali resistance of the mercerization penetrant reaches 300g NaOH / l, and the mercerization penetrant has extremely good penetration ability in 180g NaOH / l ~ 300g NaOH / l solutions.

Description

technical field [0001] The invention relates to a mercerizing penetrant mainly used in cellulose fiber mercerizing and polyester alkali reduction processes and a preparation method thereof. technical background [0002] In the mercerizing process of cellulose fiber and the alkali weight reduction process of polyester, the concentration of NaOH usually used is 180gNaOH / l-300gNaOH / l. In order to achieve good processing performance, mercerizing penetrant must be added. The mercerizing penetrant must be resistant to lye over 180gNaOH / l and must have good penetrating ability. [0003] Chinese patent 201010527958.8 discloses a highly alkali-resistant wet cloth mercerizing penetrant and its preparation method. The penetrant is isomeric tridecanol polyoxyethylene ether phosphate, which can be used in the wet cloth mercerizing process of cotton, linen fabrics and their blended fabrics. [0004] Chinese patent application 201510032538.5 discloses a phosphate ester mercerizing penetra...
