New Medical Textile Materials Technology Application Field Innovative Industry

Medical textiles

It is one of the most innovative and highest technology products in textiles.

It can be divided into four main categories: the first category is surgical implant textiles, such as suture, artificial blood vessels, artificial heart valves, artificial joints, etc. the second category is surgical non implants, such as bandages, gauze and so on; the third type is artificial organs, such as artificial kidney, artificial heart and lung; and the fourth is health care and hygiene products, such as medical sheets, surgical clothing, surgical covers, isolation sheets, diapers, sanitary napkins, adult incontinence pads and so on.

At present, the domestic medical textiles are mainly used in second categories and fourth categories. The first and third kinds of products with high technical content, although there are certain production in China, but still lack competitiveness compared with some famous brands abroad, they are mainly dependent on imports.

For safety reasons, hospitals often choose foreign brands such as DuPont, P & G, Johnson and so on to produce medical textiles.

Medical textiles must be non-toxic, non allergic and carcinogenic. No changes in physical or chemical properties can be made during disinfection.

The most commonly used natural fibers are cotton, silk and rayon rayon rayon, which are widely used as non pplant materials (wound dressing, bandages, etc.) and health care products (bedding, clothing, diapers, sanitary napkins, wiping cloth, etc.); chemical fibers often used include polyesters, polyamides, polytetrafluoroethylene (PTFE), polypropylene, carbon fiber and glass fiber.

Compared with traditional pure cotton woven medical textiles, medical nonwoven fabrics have the characteristics of high filtration of bacteria and dust, low infection rate, convenient sterilization and easy to be combined with other materials.

As a disposable medical product, nonwoven products are not only sanitary and convenient, but also effective in preventing bacterial infection and infection.

According to the comparative determination of medical cotton fabrics and medical nonwoven fabrics abroad, the infection rate of the former is 6.41%, while the latter is only 2.27%.

In Japan, the bacterial permeability of two kinds of medical textiles was tested. The results showed that more than 5000 bacteria were penetrated in only 3 minutes on the fabric, and a small amount of bacteria passed through the nonwoven fabrics 20 hours later.

Listed in the 11th Five-Year "science and technology tackling project" in the textile industry.

New medical textile materials technology

There are mainly two items: first, the development of artificial kidney, and the two is the industrialization research and development of mosquito repellent textiles.

The key technology for the development of artificial kidney is to use polysulfone and polyacrylonitrile as raw materials, hollow fiber ultrafiltration membrane is made through hollow spinning, and then assembled into dialyzer. In terms of mosquito repellent textiles, spraying mosquito repellent products are available in China, but the level of composite spinning technology is not high.

China Textile Industry Association experts pointed out that medical textiles are guided by materials and based on fabric.

。

With the diversification of demand for medical and sanitary textiles and the rapid rise of new textile materials and technologies, medical textiles are a field with great potential for development.
