Application of recycled spunbond fabrics in clothing field

2022-12-31  123

The application of recycled spunbond fabrics in clothing is mainly concentrated in the field of non durable clothing, while the application of durable clothing is rarely reported.

Recycled spunbond fabrics have been widely used in non durable clothing, such as spunlace 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 existing materials in the field of clothing application; Second, the development of new recycled spunbond fabrics.

Non durable recycled spunbond clothing fabric

SMS non-woven fabric is a spunbonded and melt blown composite product, which has the advantages of high strength, good filtering performance, no adhesive, non-toxic, etc. It has played an important role in the field of medical and industrial filtering materials. The recent application is to use SMS to make use of its characteristics of breathability, no fiber dust, and preventing the particle exchange between human body and the outside world, and to use it in pharmaceutical, bioengineering, optoelectronic processing Electrical components and chips need a highly clean production environment. Spunbonded recycled spunbond fabric is composed of high-strength continuous filament, which accounts for a large proportion in the disposable protective clothing market. The latest development is to add special additives or carry out post finishing in the production process of recycled spunbond fabric, so that the product has the functions of flame retardant, antistatic, radiation resistant, hydrophobic and moisture conductive, antibacterial, and thermal insulation.

In the development of new fibers, water-soluble recycled spunbond fabric is an environmental protection product, and its application scope is gradually expanding. The spunlace recycled spunbond fabric produced by polyvinyl alcohol water-soluble fiber 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 water-soluble film to increase the barrier performance of protective clothing. In addition, in terms of the use of new fibers, foreign countries have also developed the technology of adding super absorbent fiber (SAF) in the production process of recycled spunbond fabrics. This recycled spunbond fabric containing SAF has a particularly good soft feel and water absorption performance. When worn as a close fitting underwear, it can quickly absorb sweat from the human body and increase the comfort of the micro environment between the clothing and the human body.

In the development of new composite recycled spunbond materials, the United States has developed a new type of cotton fiber composite recycled spunbond fabric. The surface layer is a thermal bonded recycled spunbond fabric of cotton and polypropylene fibers. It is composed of two or three layers of composite materials with spunbonded fabric. The product feel is similar to that of pure cotton knitted fabric. It has the advantages of good strength and elongation, water absorption and water retention, fast wicking speed, and low pilling performance. After finishing, When the elongation is 50%, the instant elastic recovery rate can 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 military takes full advantage of the advantages of woven, knitted and recycled spunbond fabrics. The outer layer of the protective clothing is tear resistant nylon/cotton poplin, which has been treated with water repellency; The lining is recycled spunbond fabric with activated carbon; The innermost layer is tricot. Compared with the existing protective clothing, this kind of clothing not only provides soldiers with special chemical protection, but also increases the portability of the clothing, reduces the cost, and can withstand at least three times of washing.
