Problems solved by technology

This kind of dyeing process not only has many procedures and is complicated, but also consumes a lot of energy, pollutes heavily, and has a low utilization rate of dyestuffs. During the baking process, the cotton fibers are sometimes "scorched" or yellowed; Due to the backward technology, the dyed objects have defective products such as colored flowers; in addition, the dyed objects have poor hand feeling, low color fastness of only 1-2 grades, and poor air permeability

Embodiment 1

[0026] 32 counts / 2 strands of pure cotton are weaved and put into the P400 garment dyeing machine for garment refining and bleaching. The refining and bleaching solution is formulated with 1ml of penetrant red oil, 2ml of stabilizer, 9ml of hydrogen peroxide, 2g of sodium carbonate, and 1L of water. Refining and bleaching for 30 minutes at a bath ratio of 1:10-15, 95°C, and PH10.5-11. After passing the inspection, wash with water, and use 0.6% by weight of 96% acetic acid at room temperature with a bath ratio of 1:15. Under the condition of neutralization pH5.5-6.0, 30 minutes, wash with water; use cationic modifier Biwengu 1-2% by weight, at 40 ℃, bath ratio 1:10-15, PH10 for 30 minutes , and the cationic blue 54# dye M-RL and the cationic dye 29# dye X-GL are respectively made into a 0.05% dye solution, and the color is uniform and uniform on the treated fiber before proceeding to the next process; Exhaust dyeing, to be dyed pink, take 1% of the K-BL type of paint purple red...

Abstract

The invention relates to a process method for washing, dyeing and finishing pure cotton garments with blue patterns; it comprises the following steps: the pure cotton garments after weaving are fed into a garment dyeing machine, and refining and bleaching liquid is prepared according to the process formula, refining and bleaching until a predetermined time, washing with water, Neutralize and wash with water; use cationic modifier according to 1-3% of the weight of the material, carry out cationic modification treatment on cotton fiber until the predetermined time; use the formula of the color to be dyed to dye at a constant temperature until the predetermined time, wash, soap, Water washing; take 2% cellulase by weight, carry out enzyme washing and polishing treatment on the dyed object until the predetermined time, and terminate the enzyme activity under alkaline conditions; dehydration, drying, and setting. The invention reduces energy consumption and discharges pollutants to meet environmental protection requirements, improves the utilization rate of paint dyes and the qualified rate of dyed objects, and its quality fully meets or exceeds the requirements of the corresponding national or industry standards, and has a mercerized luster and long-lasting hand feeling. Soft, comfortable to wear, non-greasy feeling and good air permeability, which improves the drapability of the fabric.

Description

technical field [0001] The invention relates to a fiber printing and dyeing process, in particular to a dyeing and finishing process of pure cotton garments with blue patterns, which is the preferred method for dyeing pure cotton garments. Background technique [0002] In the past, the dyeing of pure cotton garments usually used the dyeing of paint, which must be added with adhesives and bonding agents to bond the paint to the fabric fibers, and then baked at a high temperature of 130-160°C to make it glued and fixed on the fabric fibers. on the dye. This kind of dyeing process not only has many procedures and is complicated, but also consumes a lot of energy, pollutes heavily, and has a low utilization rate of dyestuffs. During the baking process, the cotton fibers are sometimes "scorched" or yellowed; The technology is outdated, so that the dyed objects have defects such as colored flowers and other defective products; in addition, the dyed objects have poor hand feeling,...
