Non-woven fabrics in the field of medical application and quality control points

Non-woven ( English name: NonWoven) Also called nonwoven fabric, is composed of directional or random fiber, is a new generation of environmental protection material, has moisture-proof, breathable, flexible, qualitative light, no combustion, easy to decompose, non-toxic non-irritating, rich colors, with low cost, reusable, etc. Such as the use of polypropylene (more Pp material) Grain as raw material, by high temperature melting, spinning, steel, heat the top ranking paper for one-step production. Because of having the appearance of the cloth and some performance and called it the cloth. Main purpose ( 1) Health cloth: gown, protective clothing, XiaoDuBao cloth, mask, diapers, women's sanitary napkin, etc; （ 2) Family decorative cloth, wall cloth, table cloth, bed sheet, bedspread, etc; （ 3) With loaded with cloth, cotton lining, fusible interlining, flocculus, finalize the design, all kinds of synthetic leather base cloth, etc. （ 4) Industrial fabrics: filter materials, insulation materials, cement bags, nonwoven fabric and coated fabric, etc; （ 5) Agricultural cloth: crop protection cloth, base cloth, irrigation cloth, insulation curtain, etc. ; （ 6) Other: space cotton insulation, heat preservation material, linoleum, cigarette filter, bags, tea bag, etc. Medical nonwoven medical non-woven products is the use of chemical fiber include polyester, polyamide, ptfe ( PTFE) , polypropylene, made of carbon fiber and glass fiber health care textile. Including disposable masks, protective clothing, gown, isolation gown, lab coat, the nurse cap, surgical cap, doctor cap, kits, women bags, first aid kit, diapers, pillowcases, tablecloths, bed sheet, bedding bag, shoe covers and so on the disposable medical consumables series. Compared with the traditional pure cotton woven medical textiles, medical non-woven fabric has high filterability of bacteria, dust, low infection rate, disinfection sterilization, convenient, easy operation and other composite materials, etc. Medical nonwoven products as use disposable one-time items, not only convenient use, safety and health, also can effectively prevent bacterial infection and iatrogenic cross-infection. In our country, used for medical and health industry investment has amounted to one hundred billion yuan of above, the gross output value of about 64 billion yuan, health supplies and materials and to develop in the direction of diversification. Medical non-woven fabric quality control 1, medical non-woven fabric is different from ordinary non-woven fabrics and composite non-woven fabric. Ordinary non-woven fabric does not have resistance bacteria; Composite non-woven fabric waterproof effect is good, poor permeability, commonly used in gown and surgical bed sheets, etc. ; Medical non-woven fabric is using spun-bonded, melt-blown, spun-bonded ( SMS） The process of pressing, bacteria resistance, the characteristics of hydrophobic, breathable, no dander, final packaging sterilization items, for the disposable use, without cleaning. 2, medical non-woven fabric quality standard request: used for sterilization of medical equipment final medical non-woven packaging materials, and shall be in line with the GB/T19633 and YY/T0698 at the same time. 2 specification requirements. 3, non-woven fabric is the use of the period of validity: the validity of the medical non-woven fabric itself is commonly 2 ~ 3 years, the validity of the product of different manufacturer is slightly different, please refer to the instructions. With medical non-woven packaging of sterile items, the period of validity should be for 180 d, and is not affected by way of sterilization. 4, used for non-woven sterilization packaging items to 50 g/m2 and subtract 5 grams is advisable. 5, medical non-woven packaging surgical instruments, the use of closed type packing method, should be 2 layers of non-woven points two package, repeated folding can form a long winding path, prevent microbial 'easily' to enter the sterilization bags, non-woven material, not 2 layer 1 packaging. 6, medical non-woven fabric after high temperature sterilization, change the internal result, the influence on the performance of the sterilization medium penetration and resistance bacteria, therefore, medical non-woven fabric used shall not repeat sterilization. 7, due to the hydrophobic properties of non-woven fabric, too much, heavy metal equipment after high temperature sterilization, cooling, condensation water in the process of susceptible to wet package. Therefore, in the large equipment package cushion absorbent material, properly reduce the load of sterilizer, interspace between the sterilization bags, extended drying time, try to avoid to produce wet package. 8, hydrogen peroxide plasma should choose 'tyvek' non-woven, cannot use medical non-woven fabric containing plant fiber, plant fiber can absorb hydrogen peroxide. 9, although medical non-woven fabric does not belong to medical apparatus and instruments, but about the sterilization quality of medical equipment, medical non-woven fabric as the quality of packaging material itself, and the packing method is very important to ensure that aseptic level. 10, with reference to manufacturers provide conforms to the requirements of the inspection report and the product batch test report, and the physical and chemical properties of the medical non-woven fabric, acceptance, ensure the quality of products qualified. Summary for the management of the medical non-woven fabric, the manufacturer is responsible for medical non-woven fabric production quality, hospital equipment department and infection office is responsible for the qualification of the product and quality acceptance, supply room personnel responsible for sterilization packaging quality of the item, four guan qi, in order to ensure the quality of sterilization of medical devices.
