The future of Jianwei medical non-woven fabrics

Existing achievements

Medical textiles need to meet two conditions: low cost, worth stopping consumption once, and the second is to carry forward the function of 100% when using, and the function shall meet the requirements of end customers, and meet the necessary barrier, absorption and strong requirements. Due to the indirect contact between goods and human body, any chemical additives required to be used should have good biocompatibility. The price of medical nonwoven fabric is polypropylene as the secondary raw material, and its price depends on resin slice (oil as raw material) and specific consumption process. In addition, due to the large number of protective clothing that needs to meet specific specifications and reach various standards of foreign government agencies, such as FDA certification and European community approval mark, the normal sales can be stopped That is, the demand for goods has been certified, but there is no requirement for the first raw materials used. Therefore, the innovation of non-woven fabric has not really promoted the product consumer can not fully control the whole process of certification. In addition, the manufacturer also needs to seek reasonable certification system and stop properly marking the goods. The consumption of non-woven fabrics with advanced technology is filled with imaginable innovations. The new technology will promote and improve the whole process of nonwoven fabric processing, including resin slicing variety, mixing ratio, fiber fineness, shape, shape, density and thickness, filler variety, additive formula and various post-finishing methods. The above-mentioned wrists can be used together to meet the terminal The performance of consumer demand. Although nanotechnology has been used for many years, it has not been used in the nonwoven fabric processing. It can be stopped by nano coating finishing or nano particle adding into melt. The amount of nanomaterials is small. The other is to use the nanofibers with larger surface products indirectly. In the absence of any other information, the non-woven fabric can be added The total density of. Although it will bring high cost and unlimited function improvement, the use of nanotechnology in the field of non-woven fabric has been broken down recently. PGI has launched a fully commercialized Arium technology, which can consume submicron fiber, without the need for resin chip modification, and also need not reduce the cost consumption speed, greatly improving the function of non-woven fabric. In addition, it can stop improving the structure of non-woven fabric in many ways, such as the non-woven fabric consumed by other methods to stop compounding. Another technology is plasma treatment, which can improve the appearance structure of non-woven fabric, without the need to stop the post coating treatment, and improve the air permeability of non-woven fabric by 95%. The new pause of this technology includes stopping the disposal under atmospheric pressure and without vacuum. Due to the complex equipment installation and matching of the real air plasma technology, its cost is far higher than that of ordinary coating finishing. Because of the complex equipment installation and matching of the true air plasma technology, the cost is far higher than that of ordinary coating finishing This limits its popularity. The combat nonwoven fabrics facing the improvement of commodities have occupied a secondary position in the health information market, such as nursing pads, diapers and women's health products. In the future, non-woven fabrics can be used for medical stoma care. Nowadays, the fast growth of medical products market is partly incontinence goods, and also the current investment hotspot. It is hoped that the quality of life of the groups suffering from different levels of incontinence can be improved and life will be more relaxed and self-contained. The demand for high quality incontinence commodities meets the following three conditions: complex, comfortable, safe / credible, it is necessary to have good absorption, odor absorption and protection for human body. Undoubtedly, such commodities will be greatly welcomed in the market. The disadvantage of nonwoven fabric is that it can be used once, to prevent the interpenetration infection caused by the low efficiency wrist cleaning and invisible degradation, but the use of non-woven fabric also brings the result of waste addition. With the increase of the amount of medical treatment in hospitals and outpatient departments, in order to avoid the infection of surgical interpenetration, class IV Operation curtain and surgical clothing are the market with a rapid growth of medical nonwoven fabric. The market of primary masks is also very optimistic, which is conducive to the conventional use of medical staff, However, the application of medical nonwoven fabric also faces a series of achievements: covering of medical insurance and future "blood free internal surgery" - similar to the popularization of natural cavity and minimally invasive surgery, and the addition of discarded medical supplies from time to time, so the existing ordinary operation curtain can only become a transitional way. Nonwoven fabric has been used for many medical products, and the market time is presented from time to time, such as the protective clothing, curtain, surgical clothing and isolation clothing to avoid infection, etc. are all the components of human body appearance maintenance. The application of nonwoven fabrics in medical protective clothing is the flexibility. Therefore, it is the direction of development for non-woven fabrics with bidirectional elasticity and more close fitting. Due to the special compliance with human skin contact, Kraton performance polymers consume more and more attention. On the other hand, the sterile protection fragmentary (SBS) - including sterilization bags, packaging and outer packaging all need to use a small amount of non-woven fabrics. SBS is used to maintain the integrity of sterilization articles / appliances, to ensure the cleanness of transmission in different sick rooms, and the need for non-woven fabrics has better strength and durability, but no requirement for comfort. Nonwoven fabrics have also begun to be used in a small range. Although the market capacity is small, the added value is high, so there is no price pressure. Such goods include primary wound dressing and ordinary bandages, plastic clothing and repair materials. In addition, nonwoven fabric is also used in human implants, such as suture data, natural blood vessels and artificial ligaments, and has begun to play an important role in the field of implants,
