The annual production of 200000 tons of environmentally friendly short fibers project by Yizheng Chemical Fiber has been put into operation, alleviating the shortage of water jet non-woven polyester short fibers and providing an upgraded solution for the medical and health materials supply chain.
High end hydroentangled non-woven fabric is widely used in the medical and health fields such as disinfectant wipes, surgical gowns, medical gauze, surgical masks, wound dressings, etc., with extremely strict requirements for product cleanliness and purification. Since the outbreak of the epidemic, Sinopec Yizheng Chemical Fiber Water jet Non woven Polyester Short Fiber has faced a situation of supply shortage.
With the commissioning and trial production of four dedicated production lines for the Yizheng Chemical Fiber’s annual production of 200000 tons of melt spun environmentally friendly short fibers project, this situation is being effectively alleviated.
”upgraded version” of hydroentangled non-woven short fibers
The upgraded version of water jet non-woven short fibers created by Yizheng Chemical Fiber has solved the long-standing pain points and difficulties in the industry through a fully enclosed and clean production line and refined management.
On the production line of Tianjin Petrochemical’s short fiber unit with a single line output of 50000 t/a, the technical team has carried out quality research and has taken a series of improvement measures specifically for 1.56 dtex × 38 mm water jet non-woven polyester short fibers.
By improving the cleanliness of the production environment, optimizing spinning and post-treatment processes, we have successfully reduced product defects and foreign matter content, and significantly improved key physical indicators such as fracture elongation and curling performance.
“versatile” in medical and health materials
Water jet non-woven fabric has become an indispensable material in the medical and health field due to its unique properties. It adopts high-pressure water jet technology to entangle the fibers in the fiber web together, forming a non-woven fabric with certain strength and integrity.
This material has good flexibility, breathability, and water absorption, making it very suitable for medical and hygiene products.
In the medical field, water jet non-woven fabric can be applied to surgical gowns, wound dressings, medical gauze and other products. The medical adhesive tape made of water jet non-woven fabric produced by 3M Company is composed of acrylic pressure-sensitive adhesive coated on a white water jet non-woven fabric backing, which can be used for long-term adhesive applications.
This tape has biocompatibility and is suitable for intact skin. It can provide long-lasting skin adhesion for several weeks and can be used to secure medical devices.
A Quality Leap from “Having” to “Excellent”
With the improvement of global medical and health standards and the enhancement of disease prevention awareness, the market demand for high-performance and environmentally friendly materials continues to increase. The upgrade of hydroentangled non-woven short fibers is a key measure to cope with the changing market demand.
After the completion and operation of Yizheng Chemical Fiber’s annual production of 200000 tons of environmentally friendly melt spun short fiber project, the number of polyester short fiber production lines has reached 48, with the world’s most complete production lines and product varieties. The annual production capacity has exceeded 1 million tons, equivalent to the output of more than 22 million acres of high-quality cotton fields.
This production capacity scale will further consolidate the leading position of high-end and characteristic products such as hydroentangled non-woven polyester short fibers and native polyester hollow fibers in the national market.
Strategic Layout for Coping with Market Demand Fluctuations
The policy of centralized procurement with quantity in medicine has put forward higher requirements for the stable supply of medical and health materials. The National Healthcare Security Administration has issued a notice requiring further strengthening of the supply guarantee of selected products in the centralized procurement of pharmaceuticals with quantity.
The notice emphasizes that in response to the short-term surge in demand, medical institutions should be guided to enhance their foresight and planning in procurement, fully considering factors such as normal delivery cycles and changes in clinical demand caused by seasonal and epidemic diseases.
When there is a significant fluctuation in demand, it is necessary to guide medical institutions to place orders reasonably, avoid excessive hoarding, and coordinate the use of resources between medical institutions.
High end and Environmental Protection Advancing Together
Ultra pure hydroentangled medical non-woven fabric, as a higher-level hydroentangled non-woven fabric, is becoming a new trend in the industry’s development. Compared with ordinary hydroentangled medical non-woven fabrics, ultra pure hydroentangled non-woven fabrics usually use 100% natural fibers as raw materials and undergo special hydroentangled process treatment, which has higher purity and better biocompatibility.
This material is used in the medical field for products that require higher hygiene and safety, such as high-end wound dressings, surgical gowns, etc.
The ultra pure hydroentangled non-woven fabric industry in China has shown a significant industrial cluster effect. Zhejiang, Jiangsu, Guangdong and other regions have formed three major production bases, contributing a total of 75% of the country’s production capacity, with Jiangsu Province accounting for 39% of the national total.
These regions have a well-established industrial chain and supporting facilities, as well as rich reserves of technology and talent, providing strong support for the development of the industry.
Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales. It can produce various colors of PP spunbond non-woven fabrics with a width of less than 3.2 meters from 9 grams to 300 grams.
