Medical nonwoven products are medical and health textiles made of chemical fibers including polyester, polyamide, polytetrafluoroethylene (PTFE), polypropylene, carbon fiber and glass fiber. Including disposable masks, protective gowns, surgical gowns, isolation gowns, laboratory gowns, nurse caps, surgical caps, doctor's caps, surgical kits, maternity kits, first-aid kits, diapers, pillowcases, bed sheets, covers, shoe covers and other disposable medical supplies series. Compared with the traditional 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 to compound with other materials. Medical non-woven products as a disposable product that is discarded, not only convenient to use, safe and hygienic, but also effective in preventing bacterial infections and cross-infection of medical origin.
? Medical nonwoven raw materials are polyester and viscose fibers are chemical fibers, polyester and chemical fibers in the synthetic fibers, is used from the monomers refined from petroleum after polymerization and become, and viscose fibers are chemical fibers in the man-made fibers, belonging to the regeneration of cellulosic fibers, which is based on nature's timber, reeds, cotton short staple, and other cellulose as raw materials, made by the chemical processing, divided into filament and staple fibers of two kinds. Filament, also known as rayon or viscose silk; staple fibers have cotton type (also known as rayon), wool type (known as artificial wool) and medium-length fibers.
? Medical nonwoven fabrics are different from ordinary nonwoven fabrics and composite nonwoven fabrics. Ordinary nonwoven fabrics do not have bacteriostatic; composite nonwoven fabrics waterproof but poor breathability, generally used for surgical gowns and surgical sheets, etc.; medical nonwovens are spunbonded, meltblown, spunbonded (SMS) process pressed together with bacteriostatic, hydrophobic, breathable, non-dandruff characteristics, used for the ultimate packaging of sterilized items, single-use, no need for cleaning.
Although medical nonwoven fabrics do not belong to medical devices, but its existence is related to the quality of medical device sterilization, medical nonwoven fabrics as packaging materials its own quality and packaging methods to ensure the level of sterility is crucial. The purpose of the packaging of sterilized items is to make medical devices in the storage period before use to maintain the sterility of the state, so the requirements of sterile packaging materials have a good sterilization effect and isolation of the role of bacteria.
