New Technology Of Printing And Dyeing "Cold Spanfer Printing" To Desalination "Carbon Footprint"

　　 The World Expo Last week came to a close. Quanzhou's "cold spanfer printing" technology, which appeared on the occasion, attracted great attention from officials of the world information center of the United Nations Development Programme. The industry believes that this new technology The promotion will be desalinated. Spin The "carbon footprint" in the printing and dyeing field can help related enterprises to save energy significantly.

"Cold spanfer" energy consumption is particularly low.

Cold spanfer printing, known as cold spanfer printing, is named after the traditional heat spanfer printing (hereinafter referred to as "thermal spanfer printing") technology. "Thermal spanfer" can only be printed on chemical fiber fabrics, while "cold spanfer printing" uses reactive dyes, any natural cellulose fiber can be colored, including cotton, linen, viscose and other regenerated cellulose fibers.

Dr. Chung of Shanghai Changsheng textile products Co., Ltd. introduced that "cold spanfer printing" can be saved by 65% at room temperature by spanferring at room temperature, saving 40% of dye, saving water consumption of 2/3, and making the recovery rate of drainage water reach 92%. He also pointed out: "cold spanfer patterns are super expressive, and have three-dimensional effect. After printing, they feel very soft, and the color fastness is no worse than heat printing. It can greatly reduce the production cost and apply to a variety of knitted and woven fabrics, which has great market potential."

It is reported that the traditional hot printing and dyeing technology is used for production. After a line operation, the water consumption of tens of thousands of yuan output value reaches more than 100 tons, and a large amount of sewage will be discharged. Under the same conditions of water and sewage, the output value of the "cold spanfer printing" can reach 5 to 8 times, and the recovery rate of sewage can reach about 90%. In contrast, "cold spanfer printing" greatly reduces energy consumption and emissions, reducing the carbon emissions of textile and clothing production, which is now commonly known as "carbon footprint" to achieve "green printing and dyeing" effect.

"Cold spanfer" dye spanfer rate can reach 95%, in the production process omitted the traditional printing and dyeing of dyeing, washing, bleaching and other production processes, in terms of time, personnel, materials and other production costs have been reduced, and the most commendable is that "cold spanfer" energy saving and emission reduction technology, textile and clothing "low carbon production" will no longer be a problem. Wang Yanzhu, chairman of Gage (China) weaving & Dyeing Co., Ltd., chairman of the board, said that the ordinary "heat spanfer printing" solid color reached three grade, and the "cold spanfer printing" fixation reached four grade.

Printing and dyeing production

Industry veteran said that high-definition digital printing and dyeing in the textile and garment production industry has always been a luxury brand that can be consumed by high-end brands. The general clothing manufacturers can not afford the high cost of digital printing.

According to the analysis, with the production standard of one day as the standard, digital printing can only produce hundreds of rice cloth or one hundred or two hundred clothes a day, and the production capacity can not be improved. Even if other production costs are the same, it can not carry out large-scale operations, so the profit space will be greatly reduced. Cold printing and dyeing greatly advance digital printing. Under the same flow shop conditions, the daily output of cold printing can reach more than 10000 meters, while the quality of production can still maintain the same effect as digital printing.

The new technology of "cold spanfer printing" represents the development direction of printing and dyeing in the future. The "cold spanfer printing" printing method reduces dyeing links, saves a lot of energy consumption, and solves the environmental printing and cleaner production problems of dye printing better. This technology conforms to the current world low carbon environmental protection concept and requirements, and can promote Chinese textiles to enter the market of developed countries more smoothly and promote the core competitiveness of the entire textile industry.

Wang Yanzhu believes that with the increasing tension of global energy, energy conservation and emission reduction will be an important link to test the survival and development ability of enterprises. "Whoever can take the lead in seizing effective energy saving and emission reduction technologies will probably seize the opportunity in the market." He analyzed, from a strategic perspective, promoting the use of "cold spanfer printing" technology can not only make textile and garment enterprises achieve a new leap, but also promote the spanformation and competitiveness of Shishi and even Fujian and the whole country.

It is understood that the China Textile Industry Association will take the lead in integrating the advantages of the industrial chain, and will soon form a "cold spanfer printing alliance". Related manufacturers of cotton, yarn, hemp, spinning, wool and other front-end products, using "cold spanfer printing" technology to produce fabrics, and then cooperate with excellent brand clothing enterprises to produce high quality low carbon environmental protection clothing.
