How far from the age of dyeing without water

         If the printing and dyeing industry can reduce the discharge of sewage,or to achieve the absolute emissions,so regardless of Shaoxing,or the national printing and dyeing industry will further enhance the development,implementation of green environmental protection,sustainable development objectives.
         Waterless printing machine directly controlled by the computer,the dyes,auxiliaries were printed onto the fabric,get rid of the traditional printing plate,paste,printing and other complicated process,not only greatly shorten the production cycle,and printing with high accuracy,rich color,noise and waste water,waste gas,does not produce printing process.Compared with the traditional printing and dyeing equipment,meters,years to promote the yield by 100 computers,the estimated annual water-saving 130000 tons,saving 650000 kwh,saving 25000 tons of steam.
         Some enterprises will transfer paper printing technology has the advantages of anhydrous integrated flat screen printing machine,rotary screen printing,transfer printing and digital printing technology,overcome the disperse dyes on cotton and other natural fiber fabric sublimation transfer printing technology challenges,of cotton,hemp,silk has done half bleached with dip,spray,brush bar methods such as textiles,with the new regulator using a newly developed pretreatment and drying,consistent with the traditional transfer printing process.The advantages of this technology is suitable for mass production,and eliminates much of the subsequent cleaning work in printing process,saving drying by heat,can realize the waterless printing real.According to the experimental data in small and middle,a printing production line equipment,as long as the input RMB 400,000-500,000 for reform,daily reduce sewage emissions at about 35%-40%.
         Advanced printing and dyeing and finishing technology in the practical application of the enterprise,the added value of the products will effectively raise.One of the key tasks in the "Twelfth Five Year Plan" period of textile industry science and technology progress,is to increase the high efficient short process pretreatment of printing and dyeing technology,anhydrous less water technology of printing and dyeing and functional finishing technology development and promotion,less focus on the development of water and water free dyeing processing technology,for the industry to realize clean production,improve the ability of sustainable development to provide technical support.One of the new transfer printing technology is an important way to realize the less water and water free dyeing technology.
         Compared with traditional printing,the transfer printing waste water generated much less,but the transfer printing are not bright color,pattern of poor quality problems,and can only be applied on the polyester fabric.How to put the technology transfer printing on cotton,wool and other natural fabrics,if the enterprise can solve this problem,it will be a real "technology revolution",on the printing and dyeing industry is important to the development of green environmental protection.
