Golden textile” self-developed salt-free dyeing technical knowledge

A reduced asset utilisation, little ecological contamination and salt-free dyeing expertise, at a latest village is established in Shaoxing Anchang coordinate textile golden Ltd. effectively evolved and directed in bulk cotton fabric, CVC, nylon and other fibers into piece of cloth dyeing Medium. Two days before, golden textile businesses have the expertise to the National Patent Office announced 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 business unaligned study and development of non-salt and salt-free dyeing auxiliary dyeing expertise, high-tech, reduced asset utilisation, less ecological contamination, good financial comes back, to encourage the worth of highly. Last year, the business is about two-thirds of 68 million meters of dyeing fabric dyeing cotton fabric fibers, the New Year to more than 530 tons of saline, reuse, and 20,000 cubic meters of water-saving, and repairing the rate of dyestuff substantially advance, 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.
