On March 28, 2024, Zhou Xiaoming, a photographer from Yangzhou Zhenzhou Mansion and Yizheng, excerpted the information released on the official account platform of "Sinopec News Network": Yizheng Chemical Fiber expands material application scenarios, develops new uses of meltblown microfiber, is committed to polyester hollow fiber technology and product innovation, and high-end characteristic fibers fill a number of domestic gaps. The fluffiness and elasticity of the "White" winter jacket can be easily packed into a small storage bag. The garments in this collection are made from virgin polyester hollow fibers.
Yizheng Chemical Fiber uses meltblown cloth production equipment to produce soft and warm flocs.
Synthetic fibers include polyester, acrylic, nylon, polypropylene, lilon, para-aramid, etc., every day, every minute, it is by your side, or the neon dress on your body, or the pillow quilt that accompanies you to sleep...... Sometimes it turns into a table and chair for you to sit on, sometimes it blends into the wall to strengthen your home, and even it can turn into something stronger than metal to take you to the sky......
From 6 to 8 March, Yarn Expo Spring 2024 was held at the National Exhibition and Convention Centre in Shanghai. Sinopec showcased more than 60 varieties of textile raw materials in three categories, including wonderful "heat-sensitive" fibers, thermal flocs that can keep heat and flame retardant, strong body armor materials, and "high-strength" fibers that can lift the Hong Kong-Zhuhai-Macao Bridge...... Let the public intuitively feel the "magic oil".
On March 6, Sinopec hosted the "Weaving and Solid" high-end fiber product promotion conference, and released three high-end synthetic fiber products, including Yizheng Chemical Fiber Soft Thermal Insulation Flocculation and Low Melting Point Fiber, which were favored by customers.
On October 27, 2023, Yizheng Chemical Fiber Meltblown Products added a new member, and the flame-retardant meltblown warm floc made of melt-blown flame-retardant microfiber and flame-retardant polyester hollow fiber composite was mass-produced. The warmth performance of the product is increased by more than 30% under the same gram weight, and at the same time, when the open flame melts and shrinks, the open flame leaves without continuous combustion, and can be used for winter labor protection clothing in special industries such as petrochemical industry. In the post-pandemic era, this product further expands the new uses of meltblown microfiber.
In 2020, at the critical moment of epidemic prevention and control, Sinopec's party group made decisive decisions and deployments, and Yizheng Chemical Fiber made a hard-core cross-border in order to ensure the supply of masks urgently needed for people's health, and went all out to rush to build a meltblown cloth production project, starting from scratch, regardless of conditions, overcoming difficulties, fighting day and night, building the first production line with an annual output of 500 tons in 35 days, and 12 production lines with an annual output of 500 tons in 76 days, with a total annual production capacity of 6,000 tons, helping Sinopec become the world's largest. The high-quality meltblown cloth production base has effectively played the role of increasing production and ensuring quality and price reduction, showing the role of state-owned enterprises as "ballast stone" and "pillar".
In the field of cross-border meltblown fabric, Yizheng Chemical Fiber will be entrusted by the party and the people as a mission in the short term, and will be an important business in the company's transformation in the long term. In recent years, in order to play the role of meltblown device, Yizheng Chemical Fiber has successfully developed and produced a series of new products such as non-ferrous and ultra-low gas resistance melt-blown cloth and melt-blown warm floc through technological innovations such as optimizing raw materials, improving equipment, and improving the uniformity of filtration efficiency, improving quality, increasing varieties and expanding applications.
Xue Bin, a senior expert in chemical fiber technology development department of Yizheng Chemical Fiber Science and Technology Development Department, introduced that the diameter of PP (polypropylene) microfiber produced by meltblown process is only about 1/20 of the polyester hollow fiber currently used as a thermal floc. The finer the fibers, the greater the number of fibers contained in the unit volume, and the greater the specific surface area of the fibers of the same weight, which can produce more "still air". Among the three modes of heat propagation, conduction, radiation, and convection, the convective propagation coefficient is the largest and dominant. The more "still air" sequestered within a unit volume, the warmer the material will be. In addition, the use of PP meltblown microfiber and polyester hollow fiber one-time direct compounding, no need for spray bonding, safe, non-sensitive, green and environmental protection, to avoid the unfriendly factors caused by spraying.
In January 2023, petrochemical clothing made of meltblown thermal floc has begun to be tried on by some employees of petrochemical enterprises, reflecting that the thermal insulation performance is better than that of the previous cold-proof clothing, which is both warm and lightweight. According to the market demand, the development team of Yizheng Chemical Fiber's new thermal floc has tested and developed functional products such as flame retardant meltblown thermal flocculent and far-infrared meltblown thermal flocculent, and continues to expand the application of winter labor protection clothing in special industries such as petrochemical to fill the gap in the domestic market.
After the winter of 2023, Yizheng chemical fiber heat storage fiber and other virgin polyester hollow fiber series products are selling well. Yizheng Chemical Fiber takes the initiative to adapt to market changes, adjusts the product structure, focuses on the full production and sales of profitable products, and makes every effort to expand the market to expand sales and compete for share, and the sales volume of virgin polyester hollow products will go against the market, and the production and sales volume will hit a record high in 2023, maintaining the most complete varieties and the largest output in the world.
Polyester hollow fiber is the "rising star" of Yizheng chemical fiber polyester series products. In the early 90s of the last century, Yizheng Chemical Fiber introduced a polyester hollow fiber production line with an annual output of 4,000 tons, and took the lead in committing to polyester hollow fiber technology and product innovation in China. After years of product development and market development, Yizheng Chemical Fiber has developed and produced more than 30 varieties of polyester hollow fiber, such as four-hole, seven-hole, down, silk cotton, sofa type, pearl cotton, flame retardant, antibacterial, far-infrared, bamboo charcoal, etc., filling a number of domestic gaps.
In recent years, Yizheng Chemical Fiber has continued to innovate around customer needs, and has successively developed new products such as full-spectrum thermal storage fibers and ten-hole polyester hollow fibers. Among them, full-spectrum thermal storage fiber and other products have been selected as China's fiber fashion trends.
In the 2022 Beijing Winter Olympics, the cadres and employees of Yizheng Chemical Fiber are very proud, because the Beijing Winter Olympics and Winter Paralympics staff, technical officials, volunteer uniforms and security police cold-proof clothing, as well as the inner core of some Chinese Winter Olympics athletes' ski clothes and medal uniforms - multi-dimensional heat storage thermal insulation flocs, 70% of which are made of Yizheng Chemical Fiber's various functional polyester hollow fibers. The multi-dimensional heat storage and thermal insulation floc developed and produced by the joint research and development of the industrial chain not only reduces the weight by 40%, but also improves the warmth by more than 30%, and stands out from the products of more than 10 participating companies at home and abroad with the excellent performance of instant heating, long-term heat storage, light and comfortable, sweat absorption and breathability.
Yizheng Chemical Fiber employees demonstrate the fluffiness and elasticity of the "Best" cold-proof clothing, which can be easily packed into a small storage bag. The garments in this collection are made from virgin polyester hollow fibers.
High-end synthetic fiber products such as Yizheng Chemical Fiber's soft thermal insulation flocculent and low melting point fiber were unveiled at the China International Textile Yarn Exhibition.
The staff of the third department of Yizheng Chemical Fiber and Synthetic Fiber inspected the quality of the soft and warm floc.
