Non-woven materials in the field of non-durable clothing latest applications
In non-durable non-woven apparel is very popular in applications such as spunlace medical protective clothing, PP disposable protective clothing spunbond and SMS medical protective clothing. Currently, new product development in this area includes two aspects: First, the application of existing materials in the clothing area of the new development; the second is the development of new non-woven fabric.
Non-durable non-woven fabric
SMS spunbond and meltblown nonwovens are complex products with high strength, filter performance, non-adhesive, non-toxic, etc., have been in the field of medical and industrial filter material played an important role, the application is the use of newly SMS breathable, fiber does not produce dust particles with the outside world to prevent the exchange of human characteristics, to be used in the pharmaceutical, biotechnology, optoelectronics processing, electrical components and chips requires a high degree of clean production environment. Spunbond nonwoven is made of high strength continuous filament form, disposable protective clothing market share in a large proportion of the latest developments in the spun-bonded non-woven production process by adding special additives or finishing, the product flame retardant, antistatic, radiation, hydrophobic moisture, anti-bacterial, thermal and other functions.
In the development of new fiber, water-soluble non-woven fabric is an environmentally friendly product, and their use is gradually expanding. Use of water-soluble polyvinyl alcohol fiber spunlace non-woven, is to produce radiation, pollution prevention good clothing material. In order to increase the protective effect can also be combined with water-soluble membrane, increasing the barrier properties of protective clothing. In addition, the use of new fibers, woven abroad has also developed a production process to join in the super-absorbent fiber (SAF) technology. This includes the SAF has a special non-woven soft feel and good water absorption, for wearing underwear when the body can rapidly absorb sweat, increase micro-environment between clothing and human comfort.
New composite non-woven materials in the development, the United States developed a new composite non-woven cotton fiber, the surface layer of cotton and polypropylene non-woven fibers thermally bonded, and spunbond fabric composite material composed of two or three , the product and feel similar to cotton knits, with good strength and elongation, water absorption and water retention, wicking speed, a small performance advantage from the ball, after finishing, the elongation of 50% of the instantaneous elastic recovery rate can reach 83% ~ 93%, suitable for making medical Geli Fu and disposable underwear. In addition, the U.S. military developed a new generation of biological and chemical protective clothing, full use of woven, knitted and woven fabrics of three kinds of advantages, the outer layer of protective clothing is to tear nylon / cotton poplin, after refusing treatment; lining of The non-woven fabric with activated carbon; innermost layer of tricot warp knitting fabric. Compared with the existing protective clothing, such clothing to the soldiers in the special anti-chemical protection provided at the same time, adds clothing portability, and reduced costs, can withstand at least three times washing.
Durable non-woven fabric
As the non-woven drape, flexibility, strength and elongation resistance, opacity, and play ball with fabric and other aspects of the requirements of a gap, and in the appearance of the lack of certain artistic sense, and therefore the durability of clothing used in the field of considerable more difficult. However, non-woven fabric with a loose side and slippage is not easy, can be directly involved in the design side of the cloth, do not need to sew clothes for ironing and lock side edge features, which is different from woven and knitted fabrics. Non-woven garment sewing process is simple and promising advantages, many researchers and courage to face the risks of enterprise product development. In recent years, research focused on how to improve the non-woven fabrics drape, abrasion resistance, flexibility and elastic recovery capability and other properties make it suitable for fabric durability requirements.
BBAFiberweb and DowChemical developed a new joint venture company spun-bonded non-woven elastic fibers of skin-core type bicomponent fiber, core layer as an elastic body, the cortex is a good extension of the polymer, by adjusting the skin-core two components in different proportions, so that the spunbond obtained with very good elasticity, low elastic modulus and high strength and dimensional stability, durability to do this for the spunbond non-woven clothing provide the possibility.
Japan's Kuraray and domestic enterprises are jointly developed microfiber spunbond non-woven, using soluble resin and Ex Juan cevaltm PP or PE, PA, etc. composite spinning, a group was divided into PP (or PE, PA), another a combination is Excevaltm. Exce Juan valtm soluble in water below 90 ℃, but also biodegradable, and can absorb moisture and is hydrophilic in nature, and PP (or PE, PA) with a thermal bonding of the composite is very easy to form a network processing . This spun-bonded non-woven absorbent spunbond fabric is much better than the average, although its density is smaller than the strength spunbond fabric still quite traditional, is the durability of a good selection of clothing.
Spunlace non-woven with a soft, bulky, high moisture absorption, fiber material widely used and so on, is the most suitable for a non-woven clothing, therefore, its application in the study of durable clothing up. U.S. patent reported a durable spun-laced non-woven, with good wear resistance and drape, easy to play ball, color fastness, and when the machine direction perpendicular to the elongation of 50%, the response rate can reach 90 %, and at least 25 times after washing. The non-woven fabric has good elasticity, suitable for making everyday wear shirts and jackets, both personal comfort, good mechanical strength and aesthetics in one, is the ideal clothing garment materials.
