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 expertise R andamp; D staff in the objective directly after the check in the lab to do. Abroad because there is no precedent for this expertise, all depend on to perform their own study to explore. R andamp; D in alignment to change the fiber with a contradictory electric auxiliaries, mechanical employees until 2007 effectively evolved salt-free dyeing auxiliary chemicals and low-volume applications. However, they furthermore came across the difficulty of high cost of publishing and dyeing. In this consider, technical and mechanical staff in the company's powerful support of the authority, to extend research. They are low-cost chemical raw components assortment as the best synthetic additive formula; a change in the customary publishing and dyeing expertise, at the outset will be dyeing gray piece of cloth on the ambient warmth of the container, gradually through the freezing revolving mill will be one swap fabric, and then will be revolved up piece of cloth, and then put in salt-free dyeing the dyestuff vat. Numerous checks and eventually did well in apprehending the high cost of the submission 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 financial gathering unconnected examine and development of non-salt and salt-free dyeing auxiliary dyeing technical knowledge, high-tech, small supply use, less ecological toxic waste, good monetary revisits, to endorse the worth of highly. Last year, the financial gathering is about two-thirds of 68 million meters of dyeing fabric dyeing cotton material fibers, the New Year to more than 530 tons of brackish, reuse, and 20,000 cubic meters of water-saving, and fastening the rate of clothes stain highly enhance, dyeing fiber handle well, colorful.
The company's salt-free dyeing of fabric printing and dyeing technology of modern textile industry by the provincial Institute of Textile Testing Center of detection, the rubbing fastness, washing fastness, color fastness to perspiration-resistant are in line with national standards. Enterprise is in the process will be reported to the technology, create a national scientific and technological progress awards and national high-tech enterprises.
