The application of non-woven fabrics in non-durable clothing has been very popular, such as spunlace medical protective clothing, PP disposable spunbond protective clothing and SMS medical protective clothing. At present, the development of new products in this field includes two aspects: one is the new expansion of existing materials in the field of clothing applications; the other is the development of new non-woven fabrics.
Non-durable non-woven garment fabric
SMS non-woven fabric is a composite product of spunbond and meltblown. It has the advantages of high strength, good filtration performance, no adhesive, and non-toxicity. It has played an important role in the field of medical and industrial filter materials. Recent applications are Using SMS's characteristics of air permeability, no fiber dust, and preventing the human body from exchanging particles with the outside world, it is used in high-clean production environments such as pharmaceuticals, bioengineering, optoelectronic processing, electrical components, and chips. Spunbond non-woven fabrics are composed of high-strength continuous filaments, and occupy a large proportion in the disposable protective clothing market. The latest development is the addition of special additives or after the production process of spunbond non-woven fabrics. Finishing, so that the product has the functions of flame retardant, antistatic, anti-radiation, hydrophobic and moisture conductive, antibacterial, and warmth.
In terms of new fiber development, water-soluble non-woven fabric is an environmentally friendly product, and its application range is gradually expanding. Using polyvinyl alcohol water-soluble fiber to produce spunlace non-woven fabric is a good material for making anti-radiation and anti-pollution clothing. In order to increase the protective effect, it can also be compounded with a water-soluble film to increase the barrier performance of the protective clothing. In addition, in the use of new fibers, foreign countries have also developed the technology of adding super absorbent fibers (SAF) to the production process of non-woven fabrics. This kind of non-woven fabric containing SAF has particularly good soft hand feeling and water absorption performance. When it is used as an underwear, it can quickly absorb human sweat and increase the micro-environment comfort between clothing and the human body.
In the development of new composite nonwoven materials, the United States has developed a new type of cotton fiber composite nonwoven fabric, the surface layer of which is a thermally bonded nonwoven fabric of cotton and polypropylene fiber, and spunbonded fabric to form a two-layer or three-layer composite material The product feel is similar to pure cotton knitted fabric, with good strength and elongation, water absorption and water retention, fast wicking speed, and low pilling performance. After finishing, the instant elastic recovery when the elongation is 50% The rate can reach 83% to 93%, which is suitable for making medical isolation clothing and disposable underwear. In addition, the new generation of biochemical protective clothing developed by the US military makes full use of the advantages of woven, knitted and non-woven fabrics. The outer layer of the protective clothing is tear-resistant nylon/cotton poplin, which has been treated with water repellency; the lining is a belt. Non-woven fabric with activated carbon; the inner layer is tricot knitted fabric. Compared with the existing protective clothing, this clothing not only provides special chemical protection for soldiers, but also increases the lightness of the clothing and reduces the cost. It can withstand at least three washings.
Durable non-woven garment fabric
Since non-woven fabrics have gaps in drape, elasticity, strong elongation, opacity and pilling, and lack a certain artistic sense in appearance, they have considerable application in the field of durable clothing. Difficulty. However, non-woven fabrics are not easy to loose edges and slip off, can directly participate in the design of the fabric edges, and do not need to iron and seam the seams of the clothing. This is different from woven fabrics and knitted fabrics. It is precisely because of the simple advantages of non-woven garment sewing technology that many scientific researchers and enterprises have the courage to face risks and carry out product development. In recent years, the focus of research has focused on how to improve the drape, abrasion resistance, elasticity, and elastic recovery capabilities of non-woven fabrics to make them suitable for the requirements of durable clothing fabrics.
Spunlace non-woven fabric has the characteristics of soft hand feeling, bulky, high moisture absorption, and wide use of fiber raw materials. It is a kind of non-woven fabric suitable for clothing. Therefore, the most research on its application in durable clothing . The United States reported a durable spunlace non-woven fabric with good abrasion resistance and drapability, not easy to pilling, and good color fastness. When the elongation in the vertical machine direction is 50%, the recovery rate can reach 90%. , And can be washed at least 25 times. The non-woven fabric has good elasticity and is suitable for making shirts and outerwear for daily wear. It has both close-fitting comfort, good mechanical strength and aesthetics. It is an ideal clothing material.
