The application of non-woven fabrics in clothing is mainly concentrated in the field of non-durable clothing, and the application of durable clothing is rarely reported. 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 been used in the field of medical and industrial filtration materials. It plays an important role. The recent application is the use of SMS for air permeability, no fiber dust, and prevention of particle exchange between the human body and the outside world. It is used in pharmaceutical, bioengineering, optoelectronic processing, electrical components and chips and other production environments that require a high degree of cleanliness. middle. Spunbond non-woven fabrics are composed of high-strength continuous filaments and occupy a large proportion in the disposable protective clothing market.
The later development is the addition of special additives or post-finishing in the production 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 innermost layer is tricot 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.
