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 "first" 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, so as to keep warm effect. 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 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 the outbreak of new crown pneumonia was fought, Yizheng Chemical fiber primary polyester hollow fiber can be used for hospital bedding, mattress, pillow core and other purposes, to help Hubei, Shandong, Zhejiang, Tianjin and other places to fight the epidemic. Due to the enhancement of people's awareness of health and anti-bacterial, compared with the polyester hollow fiber spun by recycled recycled chips, the melt direct spinning primary polyester hollow fiber has the advantages of bulkiness and resilience In terms of color and cleanliness, 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 Yizhi will be the first one in the world in terms of annual output of 200000 tons of polyester fiber, and will further consolidate its position as the first in the global market for polyester fiber with an annual output of 200000 tons.
