Yizheng Chemical fiber original polyester hollow lead keeps two world "No.1"
On August 16, Sinopec Yizheng Chemical fiber annual output of 200000 tons of melt direct spinning environmental protection staple fiber project, the annual output of 250000 tons of primary polyester hollow fiber special production line was successfully put into operation, helping Yizheng Chemical fiber primary polyester hollow fiber business to lead the industry, and continue to maintain the most complete variety and the largest output of two "No.1" in the world.
Polyester hollow fiber, also known as hollow fiber, is a polyester hollow fiber whose diameter is less than one tenth of the hair silk. Under the microscope, the longitudinal surface of the fiber is smooth, and the transverse cross-section shape has eccentric circular hole. The asymmetric structure makes the fiber have permanent three-dimensional curl shape, forming excellent fluffy resilience. The round hole contains non flowing air, thus playing a role in keeping warm 。 In addition to the single hole, there are four holes, seven holes and other porous hollow fibers. Polyester hollow fiber has the characteristics of fluffy, resilience, warmth retention, good antibacterial and mildew resistance and light weight. It is widely used in high-grade bedding, cold clothing and other fields.
Yizheng Chemical fiber is a pioneer in the production and research of domestic polyester hollow fiber. In 1990, the production line with an annual output of 4000 tons of polyester hollow fiber was put into production, which opened the prelude of domestic production of polyester hollow fiber. In 1994, through digestion, attraction and re innovation, it built the largest domestic polyester hollow fiber production line in China, and has successively won the second prize of national science and Technology Progress Award and many other awards. After years of product and market development, Yizheng Chemical fiber polyester hollow fiber has developed and produced 11 categories and more than 50 brands of polyester hollow products, such as four holes, seven holes, Saiyu down, Saisi cotton, pearl cotton type, flame retardant, antibacterial, etc. the product quality has passed the Swiss ecological textile standard demonstration, among which, four hole, seven hole, yiwendown, antibacterial, flame retardant, heat sensitive and other varieties are filled in Domestic blank. In 2019, Yizheng Chemical fiber primary polyester hollow fiber output of 100000 tons, accounting for 20% of the domestic primary polyester hollow fiber, becoming the world's most complete and largest production of primary hollow fiber production base. Yizheng Chemical Fiber Co., Ltd. and many well-known domestic brands of home textile enterprises, occupy half of the "China good core".
In 2020, since novel coronavirus pneumonia was launched, Yizheng chemical fiber primary polyester hollow fiber can be used for bedding, mattress, pillow core and other purposes. It is very popular in Hubei, Shandong, Zhejiang and Tianjin. Due to the enhancement of health and health awareness, the melt direct spinning polyester fiber is recycled and recycled, and the advantages of fluffy and rebound are compared with that of recycled recycled polyester hollow fiber. Color, cleanliness and other advantages are obvious, the original polyester hollow fiber has been in short supply. Yizheng Chemical fiber timely completes the "addition and subtraction method" of product structure, and increases the production of primary polyester hollow fiber and other products. In the first half of the year, the sales of primary polyester hollow fiber increased by 44.68% year-on-year.
It is reported that the Yizheng Chemical fiber project with an annual output of 200000 tons of melt direct spinning environmental friendly staple fiber will be completed and put into operation at the end of August, so as to fully meet the needs of users and further consolidate the market leading position of the original polyester hollow fiber, which is two of the world's "first".
It seems that our main raw material polyester staple fiber is of great use.
