Nonwovens in the non-durable clothing has been very popular, spunlace medical protective clothing, PP disposable spunbond protective clothing, and SMS medical protective clothing, etc.. At present, the development of new products in this area include two aspects: one of the new expansion of the existing materials in clothing applications; Second, is the development of a new type of non-woven fabrics.
Non-durable material emphasis on function
SMS nonwovens spunbond and meltblown composite products, has high strength, good filtering performance, adhesive-free, non-toxic, etc., has played an important role in the field of medical and industrial filter material, new applications SMS breathable not produce fiber dust, to prevent particle exchange characteristics of the human body with the outside world, for the pharmaceutical, biotechnology, optoelectronics processing, electrical components and chip requires a high degree of clean production environment. Spunbonded nonwoven fabric is constituted by the continuous filament of the high strength, large proportion of the disposable protective clothing market. Spunbond nonwovens production process can also add special additives or finishing, the product has a fire fighting equipment, antistatic fabric radiation protection, a hydrophobic guide wet, antibacterial, warm, and other functions.
In the development of new fibers, water-soluble non-woven fabric is an environmentally friendly product, and is gradually expanding its scope of application. Spunlace polyvinyl alcohol-soluble fiber production is a good material for the production of radiation protection, pollution prevention clothing. In order to increase the protective effect with the water-soluble film composite, increase the barrier properties of protective clothing. In addition, the use of the new fiber, foreign developed super-absorbent fiber (SAF) added in the production process of the non-woven fabric. Containing SAF nonwovens soft, absorbent, used as underwear to wear quickly absorb the sweat of the human body, to increase the micro-environment of comfort between the clothing and the body.
The United States developed a new type of cotton fiber composite non-woven cloth, surface layer is thermally bonded cotton and polypropylene fiber cloth, composite of two or three layers of spunbond fabrics, the feel of cotton knitted similar, with a very good strength and elongation, water-absorbent and water retention, fast wicking speed, from the advantages of a small ball performance. After finishing this material elongation instantaneous elastic recovery rate of 50% and 83% to 93% can be achieved, suitable for the production of medical Geli Fu and disposable underwear. In addition, the U.S. military has developed a new generation of biochemical protective clothing make full use of the advantages of woven, knitted and non-woven cloth three kinds of fabric, the outer layer of protective clothing is tear-resistant nylon / cotton fiber poplin, after a water-repellent treatment, lining with activated carbon non-woven fabric, the innermost layer of tricot. Compared with the existing protective clothing, such clothing to military special anti-chemical protective and adds to the clothing portability and reduces costs, can withstand at least three times washing.
