Golden textile” self-developed salt-free dyeing technology
A low resource consumption, little environmental pollution and salt-free dyeing technology, at a recent town is located in Shaoxing Anchang organize textile golden Ltd. successfully developed and applied in bulk cotton, CVC, nylon and other fibers into cloth dyeing Medium. Two days ago, golden textile companies have the technology to the National Patent Office declared the two patents.
Golden goal is a collation of textile dyeing and printing an annual output of 80,000,000 meters of Buda company executives Jingen land attached great importance to energy saving and environmental protection. A few years ago, he and several of Donghua University in Shanghai to talk to be a Teacher information: due to the traditional dyeing process requires the use of many inorganic salts, and the application of inorganic salts there is a serious problem of environmental pollution. Therefore, there is no salt in dyeing technology research and development. However, the high cost because of the application can not be used in volume production. Lu Jin-Gen that the information immediately aware of the opportunities. Soon, he set up his own company at the salt-free dyeing technology research and development group.
Golden company’s technology R & D personnel in the mission immediately after the test in the laboratory to do. Abroad because there is no precedent for this technology, all rely on to conduct their own research to explore. R & D in order to change the fiber with a negative electrical auxiliaries, technical staff until 2007 successfully developed salt-free dyeing auxiliary chemicals and low-volume applications. However, they also encountered the problem of high cost of printing and dyeing. In this regard, scientific and technical personnel in the company’s strong support of the leadership, to continue research. They are low-cost chemical raw materials selection as the best synthetic additive formula; a change in the traditional printing and dyeing technology, at the outset will be dyeing gray cloth on the ambient temperature of the tank, slowly through the cold rolling mill will be one switch fabric, and then will be rolled up cloth, and then put in salt-free dyeing the dye vat. Numerous tests and finally succeeded in capturing the high cost of the application of this problem.
According to introduction, for the clothes stain to be adsorbed on fiber woven cloth, the conventional dyeing woven cloth each cylinder ought be one stained Add 200 kg of brackish to make fabric color. Emission of large-scale use of inorganic salts, both an advance of task strength, but in addition source ecological pollution. Salt-free dyeing auxiliary fibers can be altered to deal with its cationic covering, which in dyeing with reactive clothes stains comprising anions engendered upon the windup of staining affinity.
Golden textile company independent research and development of non-salt and salt-free dyeing auxiliary dyeing technology, high-tech, low resource consumption, less environmental pollution, good economic returns, to promote the value of highly. Last year, the company is about two-thirds of 68 million meters of dyeing fabric dyeing cotton fibers, the New Year to more than 530 tons of salt, reuse, and 20,000 cubic meters of water-saving, and fixing the rate of dye greatly improve, dyeing fiber handle well, colorful.
The company’s salt-free dyeing of fabric issuing and dyeing technical knowledge of recent textile development by the provincial Institute of Textile Testing Center of detection, the polishing fastness, bathing fastness, shade of color fastness to perspiration-resistant are in line with countrywide standards. Enterprise is in the method will be stated to the technical knowledge, bring ahead a countrywide systematic and technological improvement rewards and countrywide high-tech enterprises.
