Popularization of disposable medical non-woven fabrics

Since entering the 21st century, my country's non-woven technology has made great progress, and consumer demand has continued to grow. Non-woven equipment manufacturing, raw material production and product processing have formed a complete supply chain system, including the development of medical non-woven production and application Especially prominent. Non-woven fabrics can be further processed into artificial skin, anti-stick gauze, surgical gowns, antibacterial coverings, disinfection wraps, protective clothing, antibacterial cloths, masks, diapers, sanitary napkins, sanitary pads and civilian wipes, wipes, Wet facial tissues, towels, soft towel rolls, beauty products, etc. It is mainly produced by three processes: spunbond, hot-melt composite and spunlace. PP spunbond fabric is used for sanitary cloth, hot-melt composite fabric is used for sanitary napkins and sanitary pads, and spunlace cloth is strictly for personal care and environmental protection. Controlled surgical supplies. The latest spun web and melt blown combination of superfine melt blown fiber (diameter 2ц) and FM fine denier fiber (fineness 0.5-0.8 Den) SMS/SMMS non-woven material, the product has a soft and uniform texture, tensile strength and liquid shielding The advantages of good performance, after being treated with hydrophilic, water-repellent, antistatic and anti-aging, it is specially used for PP spunbond and SMS, spunlace non-woven fabric (viscose and polyester blended fabric) and medical needle punched elastic non-woven fabric, etc. Medical and health products processing. In 2004, the total global non-woven fabric output was 4.5 million tons. In 2005, it maintained a growth rate of 7.5%, and it is expected to reach 6.4 million tons in 2009. As the surface material of the sanitary napkin is lightweight, the total area of u200bu200bthe roll material of the same weight is increased. In 2004, the total output of domestic non-woven fabrics was 830,000 tons, with an average annual growth rate of 18% over the past four years. In 2009, the total output was close to that of the United States and comparable to Europe. The demand for disposable medical non-woven fabrics, sanitary napkins, diapers and care products is increasing. The export volume of non-woven rolls is small, and 50% of the finished products are exported. After 2003, imports of non-woven fabrics turned into negative growth, and exports grew at a rate of 16%. Spunlace and spunbond are the fastest growing non-woven fabric processes in China in recent years, followed by needle punching and thermal bonding. In the early 1990s, Taiwan Yuhao Company built the first domestic spunlace nonwoven production line in Hangzhou. In 2004, 30 spunlace nonwoven production lines were installed in China. my country’s self-developed PE/PP sheath-core composite staple fibers are used to process hot-rolled non-woven fabrics for sanitary materials. Suzhou Weishun and Shanghai Tenglong imported European equipment, and they are at the leading level among dozens of domestic hot-rolled non-woven production lines. . The hot-air non-woven fabric used to make medical and sanitary fabrics uses 100% PE/PP composite short fibers, and its polymer materials and surface treatment agents are more demanding than hot-rolled non-woven fabrics. Medical non-woven fabrics are essential for diagnosis and treatment, similar to medical protection Clothing, infectious control products, incontinence products, surgical gauze and ward equipment became hot commodities during the 2003 SARS period. On December 9, 2002, the disposable medical protective clothing independently developed by Guangdong Province with a well-developed non-woven industry was approved by the Provincial Drug Administration and became one of the few domestic counterparts at that time. However, the protective clothing fabric still relied on imports. Independent production of raw materials has brought temporary difficulties to my country's SARS prevention and control work. In the first half of 2003 alone, the domestic non-woven spunlace and spunbond production capacity increased by more than 40%. SARS has unprecedentedly promoted the development of various medical protective equipment for isolation suits and masks, and successively launched meltblown nonwovens and spunbonded, meltblown composite nonwovens SMS, SMMS isolation clothing and masks, spunbonded nonwovens and TPU moisture permeability Membrane, and various microporous breathable membrane composite products. In the year of SARS, the total consumption of medical and sanitary non-woven fabrics increased by 13% over the previous year. At the same time, the domestic medical industry has realized that traditional protective clothing, surgical gowns, masks, and wet tissues cannot meet the needs of anti-virus and comfort. The changes in the medical protective product market have paved the way for the popularization and application of high-performance and low-cost non-woven fabrics. . Spunbond meltblown (SMS and SMMS) water-repellent non-woven non-woven fabrics produced by American DuPont technology are spunbonded with filaments on the outer layer and meltblown with ultrafine fibers on the inside. Low weight, high strength and elongation; high air permeability and strong water resistance. The product has good uniformity and high opacity; the spunbond layer is composed of continuous filaments, which has good breaking strength and elongation; the meltblown layer is composed of continuous ultrafine fibers, which has a good barrier to moisture, bacteria, dust, etc. Effect; has high water pressure resistance and good air permeability; good acid and alkali resistance; can produce different colors. In the medical industry, it can be used as surgical gowns, surgical hole towels, wound care, protective clothing, hats, masks, etc.; in the sanitation field, it can be used as side leakage prevention for baby diapers and adult incontinence diapers. Special purpose medical anti-SMS (SMMS) non-woven fabric has an anti-alcohol effect of level 10 (that is, it can withstand 100% alcohol), good anti-blood and anti-oil effects; anti-static SMS (SMMS) non-woven fabric has good anti-static effect , The surface resistance is less than 108Ω, making surgical gowns and isolation gowns; Anti-mildew and antibacterial SMS (SMMS) non-woven fabrics have good antibacterial effects and are widely used in medical, industrial and sanitary environments with high requirements for microorganisms.
