Prompt:Black technology accelerates the process of chemical fiber green manufacturing

Biomaterials break the monopoly of petroleum-based products
Released in the exhibition of Chinese popular trend of fiber on 2018/2019, cathay biological industry co., LTD. (hereinafter referred to as "kay,") the development of new biological basis for the second time in polyamide - Thai nylon products.
Before the advent of this product made from renewable biomass straw, there was no enterprise in the world that could use biotechnology to industrialize polyamide products on a large scale.
"Compared with traditional petroleum-based polyamide products, the tylenol products can help the downstream textile industry reduce its dependence on petroleum-based raw materials. At the same time, the product is more functional and cost-effective. Cathay biological industry co., LTD., chairman and CEO Dr Liu Xiucai introduces to the reporter, Thai nylon as a new biological textile new material, maximum limit retained the natural fiber, the active ingredient, has close skin soft, good moisture absorption, low temperature dyeing and nature resistance characteristics. Compared with the traditional nylon fabric, the fabric made of taeron is darker and more colorful, and has obvious advantages in price.
According to the current has been commercially developed by the Thai nylon fiber products of liaoning silver bead spinning group chairman Du Xuan introduction, after repeated verification, cooperation and development of civilian is better than the traditional nylon filament yarn dyeing and moisture regain. At the same time, in the context of high prices of traditional petroleum based products and reliance on imports of core technological materials, it is a wise choice to choose bio-based fibers.
"At a time when oil resources are increasingly scarce, the use of bio-based fibers with excellent properties and renewable biomass materials will become a new growth point in the textile and chemical fiber industries in the future. At present our country has been ranked bio-based fibers' much starker choices-and graver consequences-in textile, chemical fiber industry to develop the key task, is an important component of the national strategic emerging industries, meeting the needs of national economic development." "Said jiang shicheng, an academician of the Chinese academy of engineering.
Liu xiucai revealed that as a production base for new investment in China, xinjiang usu production base will be put into production in the near future. The total investment in the first phase is more than 400 million us dollars, and it is expected to achieve an annual capacity of 50,000 tons of biovaleramines, 100,000 tons of biopolyamides and 30,000 tons of long-chain diacids. It is understood that at present, the enterprise is located in shandong jining new material park long chain diacid production base, realized industrialization in 2002, the annual capacity is 40,000 tons.
Antimony pollution from textile products is expected to disappear
In addition to the raw material end of the revolution, the technological disruption to the industry will also be revolutionary. In this exhibition, zhejiang Hengyi Petrochemical Co., Ltd launched its independent research and development of antimony polyester product of green environmental protection "from titanium kang", through the new titanium catalyst alternatives to traditional antimony catalyst, make the fiber in the process of dyeing and finishing, to avoid the precipitation of heavy metals pollution of the environment problem, implements the textiles green cycle of the life cycle.
It is known that antimony is a chemical element, like heavy metal. At present, antimony containing catalyst is the most extensive and efficient synthetic catalyst in the textile field. However, when the fiber is made and further processed in the downstream industrial chain, antimony will be released along with the rearrangement and dissociation, and then accumulated deposition will lead to soil and water pollution. According to statistics, about 10,000 tons of antimony enter the environment with textile waste every year.
"In the current new environment, the state not only has clear regulations on the content of antimony in various types of water, but also has strict inspection. Such as production facilities in the textile dyeing and finishing industries or species have been added for water pollution total emission control requirements of antimony, many textile printing and dyeing enterprises because of antimony discharge or restricting output shut down, but are not completely solve the problem of antimony pollution from the source." China printing and dyeing industry association President Chen zhihua said.
"Titanium catalyst has a high technical barriers, both to keep high activity, and to inhibit polyester products being shaded or yellowing, makes the most environmental health catalyst technology bottleneck for a long time." Zhejiang constant from petrochemical song-lin wang, executive vice President, after two years of effort, they through the independent project, independent research and development, adopt new coordination chemistry structure of titanium catalysts and compound catalysts, finally overcome the technical difficulties while production, successfully developed the domestic first and antimony series antimony catalyst products filament of the same quality level without environmental polyester products, effectively meet the needs of industrial chain manufacturer of environmental protection after.
According to one measure, head of the textile printing and dyeing enterprises, at present, an indicator only antimony, treatment of printing and dyeing wastewater t cost in a multivariate, along with the popularization and application of titanium is a catalyst, will release enormous environmental and economic benefits.
