Disposable Medical Nonwovens Are Widely Used

Since the beginning of the 21st century, China's nonwoven technology has made great progress and the consumer demand keeps growing. Nonwoven equipment manufacturing, raw material production and product processing have formed a complete supply chain system, among which the production and application development of medical nonwoven is particularly prominent. Non-woven cloth can be deeply processed into artificial skin, anti-stick gauze, surgical clothes and hats, antibacterial cover, disinfectant package cloth, protective clothing, anti-bacterial cloth, masks, diapers, sanitary napkins, sanitary pads and civil rag, wipe cloth, wet face towel, towel, soft towel rolls, beauty products, etc. Mainly using spunbonded, hot melt compound and spunbonded production process, PP spunbonded fabric division to make sanitary cloth, hot melt compound cloth for sanitary napkins and sanitary pads, spunbonded cloth for personal care and environmental protection strictly controlled surgical supplies. The newly spun mesh and SMS/SMMS non-woven material made of ultra-fine meltblown fiber (diameter 2) and Fm fine denser fiber (fineness 0.5-0.8den). The product has the advantages of soft and uniform texture, good tensile strength and liquid shielding. Specially used in PP spunbond and SMS, spunlaced non-woven cloth (viscose and polyester blended cloth) and medical acupuncture elastic non-woven and other medical products processing. In 2004, the total output of global non-woven fabric was 4.5 million tons, which maintained a growth rate of 7.5% in 2005 and is expected to reach 6.4 million tons in 2009. Due to the lightweight surface material of sanitary napkin, the total area of the same weight of the roll material increases. In 2004, the total output of domestic non-woven is 830,000 tons, with an average annual growth rate of 18% in 4 years. In 2009, the total output is close to that of the United States and equivalent to that of Europe. The demand for disposable medical nonwoven fabrics, sanitary napkins, diapers and nursing products is increasing day by day. The export volume of nonwoven coils is small, and 50% of the finished products are exported. After 2003, the import of non-woven fabric turned into negative growth, and export grew at a rate of 16%.

Spunlace and spunbond are the fastest growing non-woven processes in China in recent years, followed by needling and hot bonding. At the beginning of 1990's, Taiwan yuhao company built the first spunlaced nonwoven production line in hangzhou, and 30 spunlaced nonwoven production lines were installed in 2004. The PE/PP leather core composite staple fiber with moderate price developed by our country is used to process the hot-rolled non-woven fabric for sanitary materials. Suzhou weishun and Shanghai tenlong import the equipment from Europe, which is at the leading level in dozens of hot-rolled non-woven fabric production lines in China. Making health care product with 100% fabric hot non-woven PE/PP composite staple fiber, the requirement for high polymer material and surface treatment agent than hot-rolled non-woven medical non-woven fabric is diagnosis and treatment of necessities, like medical protective clothing, infection control products, incontinence supplies, surgical gauze and ward equipment during the period of "SARS" in 2003 to become a hot commodity. On December 9, 2002, the disposable medical protective clothing independently developed by Guangdong Province with developed nonwoven industry was approved by the Provincial Drug Administration, becoming one of the few in the domestic industry at that time. However, the protective clothing fabric still depended on imports, and the inability to independently produce raw materials brought temporary difficulties to the SARS prevention and control work in China. Only in the first half of 2003, domestic nonwoven spunlace and spunbond production capacity growth rate of more than 40%. SARS has promoted the development of isolation suits, masks and other medical protective products, and successively launched melt-blown nonwovens and spunbonded, melt-blown composite nonwovens SMS, SMMS isolation suits and masks, spunbonded nonwovens and TPU moisture permeable films, as well as various microporous permeable film composite products. In the year of SARS, the total dosage of medical health nonwoven fabrics increased by 13%. At the same time, the domestic medical community has realized that traditional protective clothing, surgical gowns, masks and wet wipes cannot meet the needs of antivirus and comfort. Changes in the medical protective products market have paved the way for the widespread application of high-performance and low-cost non-woven fabrics.

Adopts the American DuPont technology to produce the spunbonded melt-blown type (SMS and SMMS) water repellent non-woven fabric, the outer layer is spunbonded with long silk, the inside is melt-blown with superfine fiber. Low weight, strength, high elongation; High air permeability and strong resistance. Product uniformity, high opacity; The spunbond layer is composed of continuous filament with good breaking strength and elongation. The melt-blown layer is composed of continuous microfiber, which has good blocking effect to water, bacteria, dust, etc. 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 towels, wound care, protective clothing, hats, masks, etc. In the field of health, it can be used as the side leakage prevention edge of infant diapers and adult incontinence diapers.

The anti-alcohol effect of SMS (SMMS) non-woven fabric for special use can reach grade 10 (that is, it can resist 100% alcohol), and it has good anti-blood and anti-oil effect. Antistatic SMS (SMMS) nonwoven fabric has good antistatic effect, surface resistance is less than 108Ω, and operating clothes and isolation clothes are made. Smms non-woven fabrics have good antibacterial effect and are widely used in medical, industrial and sanitary environments with high microbial requirements.
