Non-woven fabric (English name: NonWoven), also known as non-woven fabric, is composed of directional or random fibers. It is a new generation of environmentally friendly materials. It is moisture-proof, breathable, flexible, light, non-combustible, easy to decompose, non-toxic and non-irritating Features such as sex, rich color, low price, and recyclable. For example, polypropylene (PP material) pellets are mostly used as raw materials, which are produced by continuous one-step method of high-temperature melting, spinning, laying, and hot-pressing coiling. It is called cloth because of its appearance and certain properties.
Main purpose
(1) Medical and sanitary cloth: surgical gowns, protective clothing, disinfection wraps, masks, diapers, sanitary napkins, etc.
(2) Home decoration cloth: wall cloth, table cloth, bed sheet, bed cover, etc.;
(3) Follow-up cloth: lining, fusible interlining, wadding, shaped cotton, various synthetic leather base cloth, etc.;
(4) Industrial cloth: filter material, insulating material, cement packaging bag, geotextile, covering cloth, etc.;
(5) Agricultural cloth: crop protection cloth, seedling raising cloth, irrigation cloth, thermal insulation curtain, etc.;
(6) Others: space cotton, thermal insulation materials, linoleum, cigarette filters, tea bags, etc.
Medical non-woven fabric
Medical non-woven products are medical and sanitary textiles made of chemical fibers including polyester, polyamide, polytetrafluoroethylene (PTFE), polypropylene, carbon fiber and glass fiber.
Including disposable masks, protective clothing, surgical gowns, isolation gowns, laboratory gowns, nurse caps, surgical caps, doctor caps, surgical kits, maternity bags, first aid kits, diapers, pillowcases, tablecloths, bed sheets, duvet covers, shoe covers, etc. Disposable medical consumables series.
Compared with traditional pure cotton woven medical textiles, medical non-woven fabrics have the characteristics of high filtration of bacteria and dust, low surgical infection rate, convenient disinfection and sterilization, and easy compounding with other materials.
Medical nonwoven products, as disposable disposable products, are not only convenient to use, safe and hygienic, but also effective in preventing bacterial infections and iatrogenic cross-infections. In my country, investment in the medical and health industry has reached more than 100 billion yuan, of which the total output value of sanitary products and materials is about 64 billion yuan, and it is developing in a diversified direction.
Medical non-woven fabric quality control
1. Medical non-woven fabrics are different from ordinary non-woven fabrics and composite non-woven fabrics.
Ordinary non-woven fabrics do not have bacteria resistance; composite non-woven fabrics have good waterproof effect and poor air permeability, and are generally used for surgical gowns and surgical bed sheets; medical non-woven fabrics are made of spunbond, meltblown, and spunbond (SMS ) Is laminated with the characteristics of anti-bacterial, hydrophobic, air-permeable, and dander-free. It is used for the final packaging of sterilized items, and it is disposable and does not need to be cleaned.
2. The quality standard requirements of medical non-woven fabrics: the medical non-woven fabrics used for the final packaging materials of sterilized medical devices should meet the specifications of GB/T19633 and YY/T0698.2 at the same time.
3. Non-woven fabric is valid for use: the valid period of medical non-woven fabric itself is generally 2 to 3 years, and the validity period of products from different manufacturers is slightly different, please refer to the instructions for use. The sterile items packaged in medical non-woven fabrics should have an expiration date of 180 days and are not affected by the method of sterilization.
4. The non-woven fabric used for packaging sterilized items should be 50g/m2 plus or minus 5 grams.
5. When medical non-woven fabrics are used for packaging surgical instruments, a closed packaging method should be used. Two layers of non-woven fabrics should be packaged twice. Repeated folding can form a long curved path to prevent microorganisms from 'easy' entering into sterilization. In the package, two layers of non-woven fabrics cannot be used for one package.
6. Medical non-woven fabrics undergo high temperature sterilization, and their internal results will change, which will affect the penetration and antibacterial performance of the sterilization medium. Therefore, medical non-woven fabrics must not be sterilized repeatedly.
7. Due to the hydrophobic properties of non-woven fabrics, excessive and heavy metal instruments are sterilized by high temperature, and condensation water is formed during the cooling process, which is easy to produce wet packs. Therefore, pad water-absorbing materials in the large equipment package, appropriately reduce the loading capacity of the sterilizer, leave gaps between the sterilization packages, appropriately extend the drying time, and try to avoid the generation of wet packages.
8. 'Tyvek' non-woven fabric should be used for hydrogen peroxide low-temperature plasma, medical non-woven fabric containing plant fiber cannot be used, because plant fiber will absorb hydrogen peroxide.
9. Although medical non-woven fabrics are not medical devices, they are related to the quality of sterilization of medical devices. The quality of medical non-woven fabrics as packaging materials and packaging methods are essential to ensure the level of sterility.
10. Refer to the inspection report and product batch inspection report provided by the manufacturer, and check the physical and chemical properties of the medical non-woven fabric to ensure the quality of the products used.
Conclusion
For the management of medical non-woven fabrics, the manufacturer is responsible for the production quality of medical non-woven fabrics, the hospital equipment department and the infection office are responsible for product qualification review and quality acceptance, and the supply room personnel are responsible for the packaging quality of sterilized items. The four-pronged approach In order to ensure the sterilization quality of medical devices.
