Alkali-resistant penetrant for short-process pretreatment of pure-cotton woven fabric

Abstract

The invention discloses alkali-resistant penetrant for short-process pretreatment of pure-cotton woven fabric, wherein the penetrant comprises the following components by weight portion: 5 to 20 portions of heterogeneous fatty alcohol polyoxyethylene ether, 10 to 25 portions of heterogeneous fatty alcohol polyoxyethylene ether phosphate, 5 to 25 portions of heterogeneous fatty alcohol phosphate, 1 to 5 portions of tributyl phosphate, and 1 to 10 portions of maleic acrylic polymer. The invention aims to overcome the deficiencies of the prior art and provide the penetrant which is used for the short-process pretreatment of pure-cotton woven fabric and has good permeability, alkali resistance and strong decontamination and washing capability.

Description

technical field

[0001] The invention relates to an alkali-resistant penetrating agent used for short-process pretreatment of pure cotton woven fabrics. Background technique

[0002] Cotton fiber is a natural fiber that contains impurities such as pigments, pectin, and cotton shells. The cotton yarn is often sized during the weaving process. Before dyeing, the impurities must be removed through desizing, scouring, and bleaching. Short-process pretreatment works faster, requiring the working fluid to penetrate into the fibers within 10 to 15 seconds, but untreated cotton fabrics are not hydrophilic, especially for heavy woven cotton fabrics, it is difficult for the working fluid to penetrate into the fibers Therefore, the alkali-resistant penetrating agent is required to have good permeability and stability under strong alkaline conditions, and the decontamination and washing performance is also required to be high.

[0003] Alkali-resistant scouring penetrant should have the...
