Problems solved by technology

[0002] Cotton textiles generally have the problems of difficult dyeing and color fixation, especially the one-time coloring rate is very low, which increases the dyeing process and time of cotton textiles, and also wastes dyes and water, causing pollution
Generally, oxygen bleaching treatment is required before dyeing. Traditional oxygen bleaching uses caustic soda, which causes problems such as poor hand feeling of fabric dyeing, easy wrinkling of fabrics, and poor reproducibility of dyeing process quality.

Abstract

The invention relates to a dyeing and finishing process, and especially relates to an oxygen bleaching process of cotton textile. The process flow comprises the steps that: an object requiring bleaching is subjected to oxygen bleaching; and liquid discharging and hot water washing are carried out. In the oxygen bleaching process, a 4-6g / L of a fast oxygen bleaching agent BLG is adopted, and 6-9ml / L of H202 (30%) is adopted, wherein a bath ratio is 1:9 to 1:12. The process comprises the advantages that: with the process, oxygen bleaching quality is uniform, thorough, and clean; fiber strength is not damaged; and oxygen bleaching process flow is shortened.

Description

technical field [0001] The invention relates to a dyeing and finishing process, in particular to an oxygen bleaching process for cotton textiles. Background technique [0002] Cotton textiles generally have the problems of difficult dyeing and color fixation, especially the one-time dyeing rate is very low, which increases the dyeing process and time of cotton textiles, and also wastes dyes and water, causing pollution. Generally, oxygen bleaching treatment is required before dyeing. Traditional oxygen bleaching is operated with caustic soda, which causes problems such as poor hand feeling of fabric dyeing, easy wrinkling of fabric, and poor reproducibility of dyeing process quality. Contents of the invention [0003] In order to ensure the reproducibility of cotton textile dyeing quality, the invention improves the oxygen bleaching process, makes the quality of oxygen bleaching even, transparent and clean without damaging the fiber strength, and shortens the oxygen bleach...
