Business club feb 10 - nonwovens application in the durability clothing have become very popular, like water thorn medical protective clothing, PP one-time spinning sticky protective clothing and SMS medical protective clothing, etc. But at present, in this field development of new products include two aspects: one is to existing materials in the clothing application domain new development; 2 it is the development of new nonwoven fabric.

The durable material function seriously

SMS nonwovens are spinning sticky and of melt-spurt complex products, have puissant tall, filter performance is good, does not contain the adhesives, non-toxic, has advantages in medical and industrial filter material field play an important role, recent application is using SMS breathable, do not produce fiber dust, stop the human body and the outside world, will the characteristics of particle exchange its widely used in pharmaceutical, biological engineering, optoelectronic processing, electrical components and chip need to be highly clean production environment. Spun-bonded fabric is made from high intensity in the continuous filament constitute, one-time protective clothing market holds a large proportion. In spun-bonded fabric production process can also add special additives or finishing, make products with flame retardant, antistatic, radiation-proof, hydrophobic guide wet, antibacterial, warmth, and other functions.

In the new textile fiber, water-soluble nonwovens development is a kind of environmental protection product, its application scope is gradually expanding. Water-soluble fiber production by polyvinyl alcohol was making water thorn cloth radiation-proof, pollution prevention clothing good materials. In order to increase the protective effect, still can and water soluble film compound, increase the protective clothing barrier properties. In addition, in the use of new fiber, foreign have also developed in nonwovens production process surpluses bibulous fibers (add SAF) technology. This contains SAF nonwovens feel soft, cleanness is strong, used for lingerie wear can quickly absorb human body of sweat, increase clothing and between the microenvironment body are comfortable.

American developed a new type of cotton fiber surface composite nonwovens, pp fiber for cotton and thermal bonding cloth, with two layers of spinning sticky cloth or three layer compound materials, products with pure cotton knitted fabric handle similar, has the very good strength and elongation, waterborne, core and the water imbibition suction speed, the advantages of pilling performance small. Through sorting, this material for 50% of the moment when elongation of elastic recovery rate can reach 83% ~ 93 percent, suitable for making medical isolation clothing and one-time underwear. In addition, the U.S. military development of a new generation of biochemical protective clothing make full use of woven, knitting and nonwoven fabric's advantages, three outer protective clothing is the anti-peel nylon/cotton poplin, after refuse water treatment, lining for the nonwoven with active carbon, the innermost layer warp knitting fabric for terry families. Compared with the existing protective clothing for soldiers, this dress in providing special against chemical protection at the same time, the more added garments portability, and reduced cost, can undergo at least 3 times catharsis.

Durable materials both beautiful and comfortable

Because nonwovens in drapability and elasticity and strong stretch sex, no transparency and a ball with fabric of the requirements, and the difference in appearance and lack of certain artistic feeling and applied in durability clothing areas are rather difficult. But, nonwoven is not easy to loose edge and slippage, can be directly involved in design, will cloth side without the need for clothing the hem for ironing and side whipstitch characteristics, distinguishes woven fabric and knitted fabrics. It is valued nonwovens garment sewing process simple advantage, many researchers and enterprise actively engage in its product development. In recent years the research focus on how to improve nonwovens drapability and wear resistance, flexibility and elastic properties such as resilience, making it suitable for durability and fabrics requirements.

BBAFiberweb and DowChemical joint venture company developed new spinning sticky elastic nonwoven using skin-core type bi-component fiber, as a kind of elastomer core layer, cortex is one kind has the very good extensibility polymer, through adjusting the skin-core two components of different proportion, which makes the system of spinning sticky with good elasticity, cloth of low elastic modulus and high strength and dimension stability, for making the durability clothing offers possibility.

Japanese coke li and domestic enterprises are jointly developed superfine fibber spun-bonded fabric, using soluble resin Excevaltm and PP or PE, PA composite spinning, etc. Excevaltm soluble in less than 90 ℃ water, also biodegradable, and can absorb water, and is hydrophilic, and PP (or PE, PA) composite thermal bonding with sexual, very easily into nets processing. This spinning sticky cloth bibulous performance is generally spinning sticky cloth is much better, though its surface density, and intensity can still smaller with traditional spinning sticky cloth quite, is the good durability clothing materials.
