As an important part of the textile printing industry, the printing and dyeing industry is an important part of the deep processing of products in the textile industry chain, improving the quality, function and value of textiles. And is also the main link of resource consumption and pollutant discharge. Its energy consumption accounts for about 30% of the textile industry. And wastewater and CODcr emissions account for more than 80% of the textile industry.
In recent years, China’s printing and dyeing cleaner production technology has made considerable progress, but it faces severe circumstances such as energy shortages, increasing shortage of water resources and deteriorating environmental pollution. At the same time, in the current traditional textile dyeing process, the dye utilization rate is low (comprehensive utilization rate is only 50%-60%), a large amount of inorganic salt is required to promote dyeing, and the long dyeing and washing process, energy consumption, and water consumption are high. It is necessary to research and develop high-efficiency short-flow low-salt dyeing and printing technologies.
The supreme new type of Sublimation Calender Transfer Machine adopts digital printing technology and completely solves the pollution problems of traditional textile printing and dyeing. The new type of thermal transfer printing machine uses thermal sublimation transfer printing paper to print on fabrics. This method is also called vapor-phase thermal transfer printing. The basic production method of transfer printing is to apply the dyestuffs to the ink first, and then print it into flower paper. Then, the paper and the fabric are overlapped together and heated, pressed or decompressed.
The dye on the sublimation paper is in a vapor state and sublimation transfer printing. To the fabric. This technology has greatly reduced the environmental problems that traditional printing and dyeing have. At the same time, it also saves labor costs and the entire printing process.
