Small "to hemostatic gauze, surgical protective masks," big "to artificial blood vessels, biological tissue patches... Medical and health textiles are showing their skills in the field of health.

Ma Pibo, a professor at the School of Textile Science and Engineering at Jiangnan University, said in an interview that medical textile research and development costs are high, technology research and development is difficult, and product quality and safety standards are strict. Through the cross-integration of textile and multi-disciplinary, continuous research and development, China's medical and health textiles have achieved product quality upgrading and performance improvement, and have been more and more widely used in surgical treatment.

Medical protective products show "healing" power

Healthy and safe functional medical textiles also show the power of textile technology in surgery and postoperative rehabilitation.

The application of single guide wet textile to surgical table pad is a typical application scenario in the field of medical pad materials. Ma Pibo said that when bleeding during surgery, skin contact with blood for a long time is easy to cause the body to lose temperature, and human comfort is poor. The single guide wet operating table pad developed by the knitting center can help the blood and body fluids flow out quickly during surgery, so that the patient's skin can keep dry. At present, the single-guide wet operating table pad has been adopted by more and more hospitals to avoid the discomfort of patients losing temperature.

Medical pressure textile can change the external pressure of the body, promote the exchange of materials inside and outside the blood vessel, tissue regeneration, repair, eliminate edema, support plasticity effect. "The use of medical pressure textiles for stress treatment is an important technique commonly used in clinical treatment." For example, Ma Pibo said that medical pressure textiles can carry out a variety of postoperative repair treatment, taking burn patients as an example, the knitting center and some hospitals cooperate, according to the patient's burn degree and different parts, the use of fully formed knitting technology to customize pressure repair products. In the part with severe burn degree, the fabric pressure was controlled by adjusting the fabric structure and spandex content to achieve the expected therapeutic effect. This kind of medical pressure textile can also be used in orthopedic fixation, sports protection, medical pressure socks and other scenes, for the treatment of fractures, varicose veins and other patients bring good news.

"We developed a medical bandage that looks like a cloth and is wrapped around the patient's fracture and immediately hardens and sets after being blown with hot air. Compared with traditional gypsum, this material can not only stabilize the affected area, prevent secondary injuries, and promote fracture healing, but also is lightweight and waterproof, so patients' daily bathing will not be affected." Ma Pibo said.

Surgical masks and medical protective clothing, as basic protective medical textiles, can effectively reduce the risk of infection of medical workers, and are the most widely used medical and health textiles.

Using flash spinning technology, high density polyethylene can be prepared into nanometer non-woven materials. This flash method of high-density polyethylene non-woven fabric combines the advantages of paper, film and cloth, with strong and durable, waterproof and breathable, soft and strong, antiviral and other advantages, is the production of high-end medical protective clothing must choose materials. Luo Zhangsheng, chairman of Xiamen Dangsheng New Materials Co., LTD., said that the company is the first to achieve an annual output of 6000 tons of flash high density polyethylene non-woven enterprises. Flash high density polyethylene non-woven fabric is the virus protection material recommended by the World Health Organization, and the company uses its nuclear dust protection clothing to fill the gap in the domestic market and achieve import substitution.

Xu Weilin, academician of the Chinese Academy of Engineering and president of Wuhan Textile University, said that in recent years, China's medical textile industry has been rapidly developed, and has been widely expanded in disease treatment and other fields. At present, the industry has the characteristics of diversification, compounding, gradual improvement of technology, and continuous innovation of functions. In the future, the industry will also develop cooperatively from multiple perspectives such as material development, performance optimization, technological innovation, and scientific and technological empowerment, and develop products with advantages such as light comfort, digitalization, intelligence, biofriendliness, and degradability to promote the high-quality development of China's medical textile industry.
