Problems solved by technology

At present, the conventional dyeing process of ready-made garments, such as tank dyeing, lifting dyeing, rolling dyeing, etc., requires a liquor ratio of 1:15-20, which requires a large amount of water, high consumption of auxiliaries, heavy sewage discharge, and energy consumption during the dyeing process. High consumption and low dye utilization
At the same time, most of the existing garment dyeing machines are paddle-type garment dyeing machines. This dyeing machine has only one paddle. It is necessary to soak more than half of the water in the dyeing tank to carry out normal dyeing work, which wastes a lot of water

Embodiment 1

[0014] Put the finished garment into the padding bucket, add dyes and additives into the padding bucket, the bath ratio is 1:1.5; apply pressure to the garment from the top of the padding bucket, and repeatedly squeeze it several times, the finished garment is squeezed and Dye evenly during the rebound process; take out the padded garments from the padding bucket, put them into the cold pile rotating device, set the rotation speed at 10 revolutions per minute, and put the finished garments in the cold pile rotating device at room temperature Rotate in medium for 8 hours to fix the dye. After testing, the dry rubbing color fastness of the finished garment is 4, the wet rubbing color fastness is 2, and the dyestuff utilization rate is 93%.

Embodiment 2

[0016] Put the finished garment into the padding barrel, add dyes and additives into the padding barrel, the liquor ratio is 1: 1.8; apply pressure to the finished garment from the top of the padding barrel, and squeeze it repeatedly, the finished garment is squeezed and Dye evenly during the rebound process; take out the padded garments from the padding barrel, put them into the cold pile rotating device, set the rotation speed at 8 revolutions per minute, and put the finished garments in the cold pile rotating device at room temperature Rotate in medium for 24 hours to fix the dye. After testing, the color fastness to dry rubbing of the finished garment is 3, the color fastness to wet rubbing is 3, and the dyestuff utilization rate is 92%.

Embodiment 3

[0018] Put the finished garment into the padding bucket, add dyes and additives into the padding bucket, the bath ratio is 1:1.5; apply pressure to the garment from the top of the padding bucket, and repeatedly squeeze it several times, the finished garment is squeezed and Dye evenly during the rebound process; take out the padded garments from the padding barrel, put them into the cold pile rotating device, set the rotation speed at 8 revolutions per minute, and put the finished garments in the cold pile rotating device at room temperature Rotate in medium for 12 hours to fix the dye. After testing, the dry rubbing color fastness of the finished garment is 4, the wet rubbing color fastness is 3, and the dyestuff utilization rate is 93%.

Abstract

The invention discloses a garment cold-batch dyeing method, and aims to simplify the technology and reduce the dye consumption and the energy consumption without changing a dye additive. The method comprises the following steps: 1, padding treatment: putting garments in a padding barrel, adopting a padding device for downwards exerting pressure on the garments from a position above the padding barrel, and repeating extrusion for several times, wherein the garments are uniformly dyed in extrusion and resilience processes; 2, cold-batch rotating treatment: taking out of the garments subjected to the padding treatment from the padding barrel, and putting the garments in a cold-batch rotating device, wherein the garments are rotated in the cold-batch rotating device at room temperature for dye fixation. Through adoption of the method, batch dyeing for the garments at room temperature can be realized without heating; compared with that in the conventional technology, the liquor ratio in the method is greatly reduced; the water consumption and the additive consumption are low; the energy consumption is reduced; the dye utilization ratio is greatly improved.

Description

technical field [0001] The invention relates to a dyeing method, in particular to a garment dyeing method. Background technique [0002] The purpose of garment dyeing is to dye white clothes into clothes of different colors according to needs. The process mainly includes washing, dyeing, oarling, cleaning, and dehydration. At present, the conventional dyeing process of ready-made garments, such as tank dyeing, lifting dyeing, rolling dyeing, etc., requires a liquor ratio of 1:15-20, which requires a large amount of water, high consumption of auxiliaries, heavy sewage discharge, and energy consumption during the dyeing process. High consumption and low dye utilization. At the same time, most of the existing garment dyeing machines are paddle-type garment dyeing machines. This dyeing machine has only one paddle. It is necessary to soak more than half of the dye tank with the water yield to carry out normal dyeing work, which wastes a lot of water yield. Contents of the inv...
