Garment Dyeing Process and Application

 

Introduction

In the modern society with the rapid development of science and technology, people have higher requirements for food, clothing, housing, use and transportation. Especially under the premise of the diversification of social forms and the general improvement of people’s living standards, people’s requirements for clothing wear function are getting lower and lower, and the requirements for clothing are also increasingly emphasizing its style, color and other personalized requirements. Therefore, the garment dyeing and finishing art has developed rapidly.People need to have diverse designs and requirements for clothing. At the same time, the development trend of fashion clothing style, fabric novelty, color diversity, personalized and traditional industrial production, large quantities of supply and demand contradiction is more prominent, small batch, multiple varieties, short process of clothing production can follow the trend of clothing fashion color development, which also promotes the development of clothing dyeing.
Therefore, the dyeing and finishing process is needed to make the garments have their own characteristics. Through the garment dyeing and finishing technology, further meet people’s design requirements.
Along with the dyeing and finishing process and its equipment has also developed a great change. Dyeing and finishing as a relatively new technology can show the unique features of different types of clothing, which is conducive to providing consumers with personalized, novel and tasteful clothing products. At the same time, it is also conducive to improving the comfort of clothing wearing, greatly improving the functionality of ready-made clothing. There are great differences in dyeing and finishing technology of various kinds of clothes.

Characteristics of garment dyeing and finishing process

Garment dyeing and finishing is mainly through the treatment of untreated fabrics and processed fabrics, after expanding the proportion size, sewing clothes according to the shrinkage rate of clothes and fabrics, and dyeing and finishing of garments, providing processing and dyeing and finishing of garments.

In the process of garment dyeing and finishing, special processing methods are needed to be processed, and dyeing and finishing equipment is used to improve the efficiency of production. Generally speaking, the dyeing process of garments is mainly processed by loose equipment. Various treatments, dyeing and finishing are carried out in the washing machine, and the garments are dried by hot air.The products processed by dyeing and finishing technology have softness, fluffiness, wrinkle-resistance and drape better than before dyeing and finishing. After dyeing and finishing the garment, the fiber on the surface of the garment is more fluffy, the feel is smooth, and the surface finish is higher. And after the special dyeing and finishing process of clothing also has other characteristics.

Advantages of garment dyeing

Garment dyeing is an intermittent processing. The pre-treatment, dyeing and post-finishing of garments are carried out in the garment dyeing machine. In the dyeing and finishing process of garments, special processing methods are needed to be processed, and dyeing and finishing equipment is adopted to improve the production efficiency. Its processing time is long, in the production, the process conditions will be due to some uncertain factors and random changes, resulting in uneven dyeing, serious cylinder difference and other phenomena.

1. Reactive dyes have little dependence on dyeing process conditions, good dyeing stability and good reproducibility. In the dyeing and finishing process of garments, special processing methods should be adopted to process and dyeing and finishing equipment should be adopted to improve the production efficiency. It is flexible to the dyeing process conditions, and can greatly reduce the color difference and cylinder difference caused by the constant random change of the dyeing process conditions, so as to reduce the repair rate and the rate of defective dyeing products, improve the labor efficiency, and have obvious economic benefits.
2. Reactive dyes have high dyeing rate and color fixation rate, full color, bright color, good compatibility, high enhancement rate and good dyeing depth. It can meet the requirements of the current garment industry, adapt to the needs of diverse color, small batch and many varieties, and greatly improve the grade of garment dyeing.In the process of garment dyeing and finishing, special processing methods are needed to be processed, and dyeing and finishing equipment is used to improve the efficiency of production. It increases the reaction probability of dye and fiber, and the fixation rate is about 80%, which is significantly improved compared with the fixation rate of single active group reactive dye. After dyeing, the dye concentration remaining in the dyeing bath is lower, the dye dosage is less. And the treatment cost of colored sewage is reduced, and the comprehensive economic benefits are significantly improved.
3. Reactive dyes are both acid and alkali resistant in chemical structure, oxygen bleaching and chlorine bleaching under general conditions, and also solve the fastness problem of fading due to broken chains in the process of using reactive dyes. It has good dyeing stability and good dyeing fastness. At the same time, but also in line with the clothing style fashion, fabric novelty, color diversification, personalized development trend.
