Medical sterilization non-woven fabric, also known as non-woven fabric, needle punched cotton, needle punched non-woven fabric, etc., is made of polyester fiber, polyester fiber (PET) material, and is made through needle punching process, which can make different thickness, hand feel, hardness, etc. It is moisture-proof, breathable, flexible, light, flame-retardant, non-toxic and tasteless, low price, recyclable and so on. Anqing Procter & Gamble to analyze in detail the product categories of medical sterilization non-woven fabrics?

Medical sterilization non-woven fabric product category

1. S: spunbonded non-woven fabric = hot rolled single-layer fiber mesh;

2. SS: spunbonded non-woven fabric + spunbonded non-woven fabric = hot rolled from two layers of fiber web;

3. SMS: spunbonded non-woven fabric + melt blown non-woven fabric + spunbonded non-woven fabric = hot rolled three-layer web;

4. SMMs: spunbonded non-woven fabric + melt blown non-woven fabric + melt blown non-woven fabric + spunbonded non-woven fabric = hot rolled from four layers of fiber mesh.

SMMs non-woven fabric belongs to composite non-woven fabric, which is a composite product of spunbonded and melt blown; It belongs to the extension of SMS non-woven fabric.

It is non-toxic, tasteless and highly effective in isolating bacteria. Through the special treatment of the equipment, it can achieve the properties of anti-static, anti alcohol, anti plasma, water repellency and water production.

Characteristics of medical sterilization non-woven fabric

1. Light weight: polypropylene resin is the main raw material, with a proportion of only 0.9, only three fifths of cotton. It is fluffy and feels good.

2. Soft: it is composed of fine fibers (2-3D) and formed by light spot hot melt bonding. The finished product is moderately soft and comfortable.

3. Water splashing and air permeability: polypropylene chips do not absorb water, with zero moisture content. The finished product has good water splashing performance. It is composed of 100% fibers, with porosity and good air permeability, and is easy to keep the cloth dry and easy to wash.

4. Non toxic and non irritating: the product is produced with FDA food grade raw materials, does not contain other chemical components, has stable performance, is non-toxic, has no odor, and does not irritate the skin.

5. Antibacterial and chemical agents: polypropylene is a chemical blunt substance, which is not eaten by insects, and can isolate the erosion of bacteria and insects in the liquid; Antibacterial, alkali corrosion, and the finished product will not affect the strength due to erosion.

6. Antibacterial property: the product has water pulling property, is not moldy, and can isolate the erosion of bacteria and insects in the liquid, and is not moldy.

7. Good physical properties: it is made of polypropylene spinning, directly laid into a net and thermally bonded. The strength of the product is better than that of general staple fiber products. The strength has no directionality, and the longitudinal and transverse strength is similar.

8. In terms of environmental protection: the raw material of most non-woven fabrics used is polypropylene, while the raw material of plastic bags is polyethylene. Although the names of the two substances are similar, their chemical structures are very different. The chemical molecular structure of polyethylene is quite stable and difficult to degrade, so it takes 300 years for plastic bags to decompose; The chemical structure of polypropylene is not firm, and the molecular chain can be easily broken, so it can be effectively degraded, and enter the next environmental cycle in a non-toxic form. A non-woven shopping bag can be completely decomposed in 90 days. Moreover, non-woven shopping bags can be reused for more than 10 times, and the pollution degree to the environment after being discarded is only 10% of that of plastic bags.

Application scope of medical sterilization non-woven fabrics

Disposable medical non-woven fabric products are medical and health textiles made of chemical fibers including polyester, polyamide, polytetrafluoroethylene (PTFE), polypropylene, carbon fiber and glass fiber. It includes disposable masks, protective clothing, surgical clothes, isolation clothes, experimental clothes, nurse hats, surgical hats, doctor hats, surgical bags, maternity bags, first aid kits, diapers, pillowcases, bedsheets, quilt covers, shoe covers and other disposable medical consumables. Compared with traditional cotton woven medical textiles, medical nonwovens have the characteristics of high filtration of bacteria and dust, low surgical infection rate, convenient disinfection and sterilization, and easy compounding with other materials. As disposable products, medical nonwovens are not only convenient to use, safe and hygienic, but also can effectively prevent bacterial infection and iatrogenic cross infection. In China, the 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 has reached about 64 billion yuan, and is developing in the direction of diversification.
