The Growth History of Medical Non Wovens
Since entering the 21st century, the non-woven technology has made great progress, and consumer demand continues to grow. Nonwovens equipment manufacturing, raw material production and product processing have formed a complete supply chain system, in particularly about the production and application development of medical non-woven fabric. Medical non-woven fabrics can processed into artificial skin, anti-stick gauze, surgical clothing, obstructing bacteria, disinfecting drape, protective products, antibacterial cloth, masks, diapers, sanitary napkins, sanitary pads, and civilian rags, wipe cloths, face towels, towels, soft towel rolls, beauty products, etc. It’s mainly produced by three processes: spunbond, hot melt compounding and hydroentanglement. PP spunbond fabrics are used to make sanitary fabrics, hot melt compound fabrics are used as sanitary napkins and sanitary pads, and spunlace fabrics are used for personal care and environmental protection.
In recent years, the spunlace method and spunbond method are the fastest growing non-woven fabrics inChina. Followed by needle punching and thermal bonding. Spunbond meltblown (SMS and SMMS) water-repellent non-woven fabrics produced inU.S.technology. The outer layer is spun with filaments and melt-blown with microfibers. Low gram weight, high strength, high elongation; high air permeability and strong water resistance. Good product homogeneity, high opacity; spunbond layer consists of continuous filaments, has good breaking strength and elongation; meltblown layer consists of continuous microfibers, good barrier to moisture, bacteria, dust, etc. High resistance to water pressure and good air permeability; Good acid and alkali resistance; Can produce different colors. In the medical industry, it can be used as a surgical gown, surgical hole towel, wound care, protective clothing, hats, masks, etc. In the field of hygiene, it can be used as a side leakage prevention tape for baby diapers and adult incontinence diapers.
