Abstract

The invention discloses a cold-stacking high-whiteness saving-type dyeing and finishing pretreatment process for a towel fabric under a reclaimed water condition, and belongs to the technical field of textile printing and dyeing. The specific operation steps are as follows: (1) cold-stacking, wherein a process formula and dosage are as follows: 30-50g / L of 30% caustic soda, 70-90g / L of 27.5% hydrogen peroxide, 4-10g / L of a quick scouring agent KR-9BK and 10-20g / L of a quick scouring agent KR-9DW are adopted, the stacking temperature is 35 DEG C, and the stacking time is 8-30 hours; and (2) bottom boiling, wherein the technological formula and dosage are as follows: 8-20 g / L of 27.5% hydrogen peroxide and 0.4 g / L of a whitening agent are adopted, the bottom boiling temperature is 97-100 DEG C, the bottom boiling time is 50 minutes, and the bath ratio is 1: 10; The whiteness, strength and hand feeling of the semi-finished product and the finished product are better than those of the semi-finished product and the finished product in the prior art, and the process can shorten the working time, improve the production efficiency, reduce the consumption of chemicals, reduce the sewage discharge and bring remarkable indirect economic benefits.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, in particular to a cold-pile high whiteness saving dyeing and finishing pretreatment process for towel fabrics under the condition of reclaimed water. Background technique [0002] The printing and dyeing industry is a large traditional water user in the national economy, and the dyeing and finishing process has high quality requirements for water quality. Specific to the towel dyeing and finishing industry, the main colors are white and light bright colors; in order to produce towel products with crystal clear whiteness or bright light colors, the requirements for water quality are even stricter. Water quality requirements: chromaticity (platinum cobalt degree) ≤ 10, pH value 6.5-8.5, total hardness ≤ 150mg / L. [0003] Over the years, with the efforts of factory management and technical personnel, the towel dyeing factory has a mature and stable pre-treatment process for tow...
