Abstract

The invention discloses a leveling agent for cotton. The leveling agent is prepared from raw materials in parts by weight as follows: 16-30 parts of glycerinum, 10-20 parts of sodium tetraborate, 6-12 parts of a caustic soda liquid, 10-16 parts of sodium gluconate, 15-25 parts of sodium dinaphthylmethane disulphonate, 2-4 parts of glacial acetic acid and 10-16 parts of deionized water. The leveling agent for cotton does not contain alkylphenol ethoxylates, adsorbable organic halides and other forbidden substances and is soluble in water, acid-resistant, alkali-resistant, hard-water-resistant, low-foam and convenient to use.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a leveling agent for cotton prepared by mixing multi-component raw materials without containing prohibited substances and a preparation method thereof. Background technique [0002] With the promulgation and implementation of ISO14000 and the increasingly higher requirements for ecological textiles and environmental protection in domestic and foreign markets, environmentally friendly auxiliaries have become products that domestic and foreign textile auxiliaries manufacturers are competing to develop. [0003] In the fabric dyeing process, various dyes are used according to the characteristics of the fibers. When various dyes are used for fiber dyeing, uneven dyeing often occurs, resulting in color flowers. The most commonly used method to solve uneven dyeing is to add leveling agent during dyeing process. Leveling agent is an auxiliary agent that can enhance ...
