Vulcanized black jean garment washing process

Abstract

The invention relates to a vulcanized black jean garment washing process. The vulcanized black jean garment washing process comprises the following steps of placing preprocessed jean garments into desizing solution for desizing treatment at 0-60 DEG C for 10-30 minutes, draining the desizing solution and washing the desized jean garments in clean water at room temperature; placing the desized jeangarments into enzyme solution for treatment at 30-40 DEG C for 15-60 minutes, draining the enzyme solution and washing the treated jean garments in clean water at room temperature; placing the treated jean garments in rinsing solution for treatment at 40-50 DEG C for 10-50 minutes, draining the rinsing solution and washing the rinsed jean garments in clean water at room temperature; adding dechlorinating deodorant into the rinsed jean garments for treatment at 30-40 DEG C for 5-15 minutes, draining the dechlorinating deodorant and washing the treated jean garments in clean water at room temperature; dewatering and drying the first-neutralized jean garments, spraying PP (polypropylene) solution onto the surface of the jean garments, then washing the jean garments in clean water; treating the PP-processed jean garments with hydroxylamine sulfate at 20-50 DEG C for 5-15 minutes, draining the hydroxylamine sulfate, and washing the treated jean garments in clean water at room temperature;processing, dewatering and drying the second-neutralized jean garments. Compared with the prior art, the vulcanized black jean garment washing process is environmentally friendly and safe, and the processed jean garments can be higher in performance.

Description

technical field [0001] The invention relates to the field of fabric washing, in particular to a washing process for vulcanized black denim garments. Background technique [0002] Denim clothing has always belonged to fashion clothing. A piece of ordinary jeans can show various patterns after different washing processes, such as cat whiskers, holes, fraying, tassels, embroidery and so on. Denim fabric can be divided into elastic, non-elastic, slub, mercerized, coated denim, etc., and some people can be divided into ordinary denim, combed denim, cotton denim, polyester cotton denim, slub denim, gold and silver silk striped denim, hemp cotton Denim, Tencel denim, etc. Denim fabrics are also distinguished according to different thicknesses, such as 4.5A, 6A, 8A, 11A, 12A, 13.5A, 14.5A, etc. Generally, most of the jeans worn normally are 8-12A. Denim fabric can also be divided into indigo denim, blue-black denim, vulcanized black denim, colored denim, etc. according to differen...

AI Technical Summary

Problems solved by technology

[0006] Due to the characteristics of dyes, the following problems exist in the washing process of sulfurized black denim: 1. Because sulfurized dyes need sulfurized alkali to be reduced first, sulfurized alkali has a smell of sulfur, so sulfurized black denim fabrics also have a smell The smell of eggs is quite unpleasant; 2. During the washing and bleaching process of vulcanized black denim, high temperature and high alkali are required, as well as a large amount of hydrogen peroxide for bleaching and desizing, which pollutes the water environment relatively; 3. Vulcanized black denim is sprayed with monkeys. Or after frying the snowflake process, the whiteness is not high, and the overall washing contrast is not obvious

[0011] The traditional vulcanized black denim washing process generally has the following problems and shortcomings. 1. The use of caustic soda and hydrogen peroxide is large. Both caustic soda and hydrogen peroxide are dangerous chemicals, and it is inconvenient to purchase raw materials, especially hydrogen peroxide. It needs to be filed and registered with relevant departments , and it is necessary to make a ledger when using it, and the competent department will regularly check the whereabouts of raw materials; 2. The processing temperature of desizing treatment is too high, the energy consumption is large, the process is not energy-saving, and the temperature is too high to cause damage to fabrics containing spandex elasticity. 3. After vulcanized black denim has been boiled, bleached, and processed by various processing techniques, some decomposed sulfur dyes will remain on the fabric, and these residual dyes will emit a smell of sulfide alkali. Very unpleasant smell, especially after heat treatment; 4. After spraying PP or frying snowflakes, the white area is difficult to clean, the whiteness is low, and the contrast between black and white is not obvious; 5. After processing, it is easy to be damaged by silicone oil, oxidation , light and other causes of yellowing
