Nonwovens Are Widely Used In Garments.

The application of non-woven fabrics in non durable clothing has been very popular, such as Spunlaced medical protective clothing, PP disposable spunbonded protective clothing and SMS medical protective clothing.

At present, the development of new products in this field includes two aspects: first, the new expansion of the existing materials in the field of clothing application; and the two is the development of new non-woven fabrics.

Non durability

SMS non-woven fabric is a composite product of spunbonded and melt blown. It has the advantages of high strength, good filtration performance, no adhesives and no toxicity. It has played an important role in the field of medical and industrial filtration materials. Its latest application is to use SMS to ventilate, produce no fiber dust, and prevent particles exchange between human body and the outside world. It is used in pharmaceutical, bioengineering, optoelectronic processing, electrical components and chips and other highly clean production environments.

Spunbonded nonwovens are made of high strength continuous filament and occupy a large proportion in the market of disposable protective clothing. The latest development is to add special additives or after finishing in the process of spunbonded nonwovens production, so that the products have the functions of flame retardance, antistatic, radiation protection, hydrophobic and moisture conducting, antibacterial and thermal insulation.

In the development of new fiber, water-soluble non-woven fabric is an environmentally friendly product, and its application scope is gradually expanding.

Spunlaced nonwovens produced by polyvinyl alcohol water-soluble fiber are good for making radiation protection and pollution prevention garments.

In the development of new composite nonwovens, the United States has developed a new type of cotton fiber composite nonwovens, the thermal bonded non-woven fabrics with cotton and polypropylene fibers on the surface, and two or three layers of composite materials with spunbonded fabrics. The products are similar to pure cotton knitted fabrics, and have good strength and elongation, water absorption and water retention, fast suction speed and low pilling performance. After finishing, the instant elastic recovery rate of the elongation reaches 50% to reach 83% ~ 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 Army makes full use of the advantages of three kinds of fabrics woven, knitted and non-woven. The outer layer of the protective clothing is tearing nylon / cotton fiber poplin, which is treated by water repellent treatment. The lining is non-woven with activated carbon and the most inside layer is tricot warp knitted fabric.

Compared with the existing protective clothing, this kind of clothing can provide chemical protection for military personnel, at the same time, it also increases the lightness of clothing and reduces the cost. It can withstand at least 3 times of washing.

Durable nonwoven fabrics

Because of the difference between the non-woven fabrics in drape, elasticity, strength and elongation, opacity and pilling, and the lack of a certain artistic sense in appearance, it is quite difficult to apply in the field of durable clothing.

Nonwovens, however, have the characteristics of not easily dispersing and slipping, which can directly involve selvage design and do not need to ironing and locking the edges of garments. This is different from woven fabrics and knitted fabrics.

It is optimistic about the advantages of sewing technology of non-woven fabrics, and many researchers and enterprises are brave enough to face risks and develop products.

In recent years, the research focuses on how to improve the drapability, abrasion resistance, resilience and resilience of non-woven fabrics, and make them suitable for durable fabric.

The BBAFiberweb and DowChemical joint venture developed a new spunbond elastic nonwovens. The fibers are core and core fibers. The core layer is an elastomer. The cortex is a polymer with excellent elongation. By adjusting the different proportions of the two components of the core, the spun bonded nonwovens have very good elasticity, low elastic modulus, and high strength and dimensional stability. This provides the possibility for spunbonded nonwovens to make durable clothing.

Japan cola and domestic enterprises are jointly developing ultra-fine fiber spunbond non-woven fabrics, using Ex cevaltm soluble resin and PP or PE, PA and other composite spinning, one component is PP (or PE, PA), the other combination is Excevaltm.

Excevaltm is soluble in water below 90 degrees, and can also be biodegradable. It absorbs water and is hydrophilic. It has thermal adhesion with PP (or PE and PA) and is very easy to mesh.

This spunbonded nonwoven fabric has much better water absorbability than the conventional spunbonded fabric. Although its surface density is small, its strength can still be the same as that of traditional spunbonded fabric, so it is a good material for durable clothing.

Spunlaced nonwovens have the characteristics of soft handle, bulging, high moisture absorption and wide use of fiber materials. They are the most suitable non-woven fabrics for clothing. Therefore, most of them are applied in durable clothing.

The US patent has reported a durable spunlaced nonwovens with good abrasion resistance and drapability. It is not easy to pilling and has good color fastness. When the elongation of the vertical machine 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 coats for everyday wear. It has the characteristics of close comfortableness, good mechanical strength and beautiful appearance. It is an ideal clothing material.
