Denim Washing Process

 
  After decades of rapid development, China's denim industry has made brilliant achievements and established an important position in the 
international market. The export of high-end products of traditional denim clothing is mainly concentrated in the markets of the United States, 
Europe, Japan and South Korea. These markets have gradually increased the requirements for environmental protection, functionality and 
fashion of denim clothing, and the requirements for the construction of social responsibility of processing enterprises have become increasingly 
strict.At present, the processing and production of denim garments in China has formed a complete modern industrial chain, and the R&D, 
design and marketing capabilities of denim garments are rapidly improving. Fashion capitals in international markets such as the United States 
andEurope have established R&D centers to promote the upgrading and structural adjustment of the domestic denim industry.

【Introduction to New Denim Washing Technology】
(1) Ozone washing technology
Ozone technology has many application advantages in denim garment processing, including reducing water and chemical consumption, 
shortening process time and flow, and being clean and environmentally friendly. The ozone washing machine can apply the ozone generated 
by the ozone generator to the washing process of garments, and produce decolorization and bleaching effects through ozone. This type of 
equipment is mainly used for the distressing treatment of denim products. By adjusting the amount of ozone generated, different degrees of 
treatment can be achieved. Effect. The ozone water washing machine does not need to use chemicals, which can save a lot of water 
resources, so it meets the requirements of ecological environment protection. Ozone is a strong oxidizing gas with super decolorizing ability for 
all dyes. Ozone can destroy the chromophore and auxochromic groups of these dyes, so as to achieve decolorization effect. The core 
technology and equipment of the ozone system is the discharge tube in the generator, which directly affects the operating efficiency and 
reliability of the equipment. In addition, the use of ozone finishing technology can realize the processing and production of different styles of 
denim clothing, giving denim clothing a unique new effect, so that the denim fabric not only reflects the roughness of the denim in terms of 
vision and function, but also shows a comfortable and soft feel.

2) Laser process
The principle of laser washing is to use a computer to precisely control the laser beam to perform high-temperature etching on the surface of 
the fabric. The yarn in the etched part is ablated, and the dye is decomposed and vaporized, thereby producing a pattern or a specific washing 
effect. When the laser beam passes over the jeans, the finishing process of a pair of jeans is basically completed. After that, only ordinary 
washing is required to remove the floating color on the surface. This technology has revolutionized the traditional finishing technology of jeans. 
breakthrough.

The light laser system provides design imagination space for clothing designers. More meaningfully, this technology can be directly applied to denim 
pursuit of individual trends. The denim industry is a traditional industry and a big industry. Continuously using high technology to connect with traditional 
industries is an important way to improve the technical content of traditional industrial products. Denim fabrics can get good wearing effect and aesthetic 
effect through dyeing and technical finishing. The denim laser process combines the flexibility of the denim itself, and its processing effect has an 
unparalleled advantage. In the denim processing process, it is no longer necessary to use cumbersome and complicated processing technology , and 
directly use laser technology to produce artistic patterns on the surface of denim, which i include text, numbers, patterns, logos，images, you can even 
accurately get the washing effects of horseshoe, cat whiskers, tattered, old, whitened and so on. The laser laser machine not only satisfies the diverse and 
complex production and processing technology of jeans, but also is energy-saving, environmentally friendly, efficient, and more fashionable.

(3) The spraying PP robot is a special robot mainly used for surface coating work, which is the product of the combination of robotics and surface spraying
 technology. The PP spraying robot can meet the needs of environmental protection, efficiency and flexible production, so it is expected to replace all 
manual operations in modern spraying lines. Spraying intensity, uniformity, details, etc. are important indicators for evaluating the quality of sprayed PP. 
Spraying robots can easily meet the requirements of safe, environmentally friendly, efficient and high-quality spraying, which is an inevitable trend in the 
development of automatic spraying technology in the future.
