To explore when China's printing and dyeing industry into the "waterless printing and dyeing" era
"If the printing and dyeing industry can reduce the discharge of sewage, or to achieve water-free emissions, whether it is Shaoxing, or the national printing and dyeing industry will further enhance the development and achieve green environmental protection and sustainable development goals." Recently held in my county, "textile industry Water less hydration printing and dyeing new technology advanced seminar "opening ceremony, China Textile Industry Federation Vice President Yang Jichao directly pointed out that the future of textile printing and dyeing industry's way out and direction.
Shaoxing County, the printing and dyeing industry accounts for about three percent of the country's total, the face of printing and dyeing sewage problems, some county enterprises in the technology research on the practice worth learning from.
Dongsheng Technology: digital printing to achieve waterless printing
Located in Taoyan town of Shaoxing Dongsheng Digital Technology Co., Ltd. since its establishment in 2008, has been committed to the waterless printing technology research, and has declared 12 patents, including 4 invention patents, utility model patents 7. Among them, GBPM (Ⅰ) -180 type textile waterless printing machine through the provincial new product identification.
According to reports, the company's waterless printing machine directly from the computer control, the dye, additives sprayed onto the fabric, from the traditional printing plate, pulp, printing and other complicated processes, not only greatly shorten the production cycle, and Printing high precision, rich colors, printing process does not produce noise and waste water, waste gas and so on. Compared with the traditional printing and dyeing equipment, according to million meters of output, the annual promotion of 100 units, is expected to save 130,000 tons per year, saving 65 million kwh, saving 25,000 tons of steam.
Benniu printing and dyeing: transfer cotton paper printing clean
If the "Dongsheng Digital" innovative technology is only suitable for small batch production, then, located in Keqiao Economic Development Zone, Shaoxing County, Benniu anhydrous printing and dyeing technology companies are looking for a more suitable for the current county printing and dyeing enterprises for the production of new methods.
The training activities, "Benniu dyeing" General Manager Chen Junliang with the company's research and development team to come to learn. Chen Junliang said the company has a new technology of waterless printing and dyeing research and development has been a breakthrough, and began a small range of applications.
It is reported that the company's research and development of waterless transfer cotton paper printing technology combines flat screen printing, rotary screen printing, transfer printing and digital printing technology advantages, overcome the disperse dye cotton and other natural fiber fabric dye sublimation transfer printing technology problems, The cotton, hemp, silk and other textiles which have been well semi-bleached are selected to be dip-coated, sprayed and brushed, etc., and the new transfer agent developed by the company is used for pretreatment and drying. The advantages of the technology is suitable for mass production, and eliminates the printing process a lot of follow-up cleaning work, saving the drying with heat, can achieve real waterless printing. According to the company's small test and pilot test data, a printing production line equipment, as long as four or five million yuan to transform, the daily sewage reduction in 35% -40%.
Printing and dyeing industry: looking forward to less water and less water dyeing and printing technology
"Advanced dyeing and finishing technology in the enterprise's practical application, the added value of products will effectively enhance." Yang Jizhao pointed out that the "second five" during the textile industry, one of the key tasks of scientific and technological progress is to increase printing efficiency short Water pre-treatment technology, water less water dyeing technology and functional finishing technology research and development and promotion, focusing on the development of water and water-saving printing and dyeing high-tech processing for the industry to achieve cleaner production and improve the capacity for sustainable development to provide technical support. "One of the new transfer printing technology is to achieve less water and waterless printing and dyeing technology is an important way." Yang Jizhao said.
Analysis of the industry, compared with the traditional printing, the current transfer printing produced less sewage, but the transfer printing color is not bright, poor quality patterns and so on, and can only be applied in the polyester fabric. How to transfer printing technology used in cotton, wool and other natural fabrics, if the relevant enterprises to solve this problem, it will be a real "technological revolution", the printing and dyeing industry to play an important role in the development of green environmental protection.
