Environmentally Friendly Dye Additives Become Hot Spots in the Textile Industry

Environmentally Friendly Dye Additives Become Hot Spots in the Textile Industry Recently, the 13th China International Dye Industry and Organic Dyestuffs, Textile Chemicals Exhibition was also held in Shanghai. At this year's show, environmental friendly additives continue to be a focus of attention. During the “Twelfth Five-Year Plan” period, the textile industry will break through 50 key technologies and cover new spinning, weaving, printing and dyeing, and high-performance industrial textile processing. The environmental protection of textiles and textiles production is highly valued. No poisoning, no Contaminated "green fabrics" have become a mainstream for production and consumption.

At the conference, several corporate technical representatives shared their understanding of dye auxiliaries in an environmentally friendly manner. According to Xu Chengxiang, director of Yongguang Chemical Marketing Department, with the trend of personalized fashion, the demand for printed fabrics has steadily increased, but its process equipment and procedures are lengthy. In addition to high effluent, the reproducibility and image stability of all parts of the fabric have been It is a great challenge. The introduction of automated pulping equipment will help improve production stability. In addition, with the growing maturity of digital printing hardware, software and supporting inks and technologies, the collocation and convergence of screen printing and digital printing is also an important issue. He discussed the help of printing liquid fuels on environmental protection, etc., as well as the importance of quality, he also mastered and analyzed the key elements of reproducibility and dyeing and anti-dyeing of printing quality, as well as the key issues and network of digital printing. Integrated elements of India were discussed.

Since production technology has to be reformed and opened to the outside world, China's printing and dyeing industry has entered a period of rapid growth. Printing and dyeing manufacturing industry has thus started. When the low-end demand for domestic printing and dyeing gradually becomes saturated, with the opening of the international market, China's printing and dyeing industry has integrated into the global trade chain. Has become the world's processing plant, but when the world economy is paralyzed by the subprime mortgage crisis, China's labor advantage is no longer, and the printing and dyeing industry has also entered a critical period of transformation and upgrading. However, in the current complex situation, it is not feasible for Chinese printing and dyeing companies to rely on technology as a means of breaking through.

Ma Xueya, chief engineer of Shanxi Caijia Printing and Dyeing Co., Ltd., discussed the technical principle of the cotton fabric-bath continuous low temperature bleaching process. Through the use of self-developed low temperature refining bleaching agents, the process innovation and breakthrough were realized, and the reaction temperature was reduced and the reaction time was shortened. , Significantly reduced the amount of steam, water, electricity and chemicals while reducing the PH value and COD of the sewage, so as to achieve the effect of energy conservation and emission reduction. Through popularization and application, according to different types of equipment and processes, the corresponding supporting process plan was studied to facilitate the promotion.

Zhang Jianguo, manager of Shenghong Group, elaborated the dyeing and finishing of 300T Nisi textile dyeing and printing fabrics. Gaomi Nisifang is a class of high-grade fabric that has become popular in recent years. After a series of dyeing and finishing processes, its texture is light and thin. It has a soft, smooth feel and a delicate cloth, and it is deeply loved by consumers. Taking the dyeing and finishing of 300T Nisi textile dyeing and printing fabrics as an example, he started the process of pretreatment, dyeing, printing, and finishing, systematically introduced the entire process of such high-density silk yarn dyeing and processing, and summarized such products. The technical problems that emerged in the processing and proposed mature solutions.

The continuous advancement of technology in the printing and dyeing industry is inseparable from the exchanges and learning between companies, and there has been a marked increase in industrial technology exchange activities. For the industry to continuously improve product added value and reduce environmental pollution, played a good role in promoting.
