Application expansion of PP spunbond non-woven fabric

by:Sunshine     2021-04-11
PP spunbond non-woven fabrics such as spunlace medical protective clothing, PP disposable spunbond protective clothing and SMS medical protective clothing, etc. At present, the development of new products in this field of polyester non-woven fabrics 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.


1. Non-durable impregnated non-woven fabric for clothing


PP spunbond 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 filtration materials. The recent application is the use of SMS, which is breathable, does not produce fiber dust, and prevents the human body from exchanging particles with 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. Spunbond non-woven fabric is composed of high-strength continuous filaments. It occupies a large proportion in the disposable protective clothing market. The development is to add special additives or post-finishing during the production of spunbond non-woven fabrics to make the product It has the functions of flame retardant, antistatic, anti-radiation, hydrophobic and moisture conductive, antibacterial, and warmth.


PP spunbond non-woven fabric is a kind of product in the development of new fiber, 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. It can quickly absorb human sweat when worn as an underwear, and increase the micro-environment comfort between clothing and the human body.


PP Spunbond Nonwoven Fabric 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 is a thermally bonded nonwoven fabric with cotton and polypropylene fibers. The cloth is composed of two-layer or three-layer composite material. The product feels similar to pure cotton knitted fabric. It has good strength and elongation, water absorption and water retention, fast wicking speed, and low pilling performance. After finishing, it stretches When the length is 50%, the instantaneous elastic recovery 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 tape Non-woven fabric with activated carbon; inner 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. 1. Stability is better than polypropylene non-woven fabric


PP spunbond non-woven fabric is mainly manifested in: strength, abrasion resistance and other properties. Because polyester non-woven fabrics use special raw materials, they are produced by advanced imported equipment and complex and scientific processing techniques, which have far exceeded the technical content and requirements of polypropylene non-woven fabrics.


2. Heat resistance is better than polypropylene non-woven fabric


Polypropylene non-woven fabric has obvious heat shrinkage. According to investigation, there will be significant shrinkage when the temperature reaches 140 ℃, while the temperature of polyester non-woven fabric can reach about 230 ℃, which is obvious compared with polypropylene non-woven fabric. Characteristics.


3. Anti-aging cycle is higher than polypropylene non-woven fabric


Polyester non-woven fabric uses polyester as raw material, which is resistant to insects, abrasion, and ultraviolet rays. The above characteristics are higher than polypropylene non-woven fabrics.


Fourth, has good air permeability


Compared with polypropylene and other non-woven fabrics, polyester non-woven fabrics have excellent properties such as non-absorbent, incompatible with water, and strong air permeability.


The first is the difference in raw materials: PP refers to polypropylene, which is polypropylene; PET refers to polyester, which is polyethylene terephthalate.


Secondly, the two types of non-woven fabrics are quite different in application, but they can be substituted for each other in some aspects. It's just a difference in performance.


In addition, in the way of production and processing, these two have the same and different. Different processing methods determine the application in most cases.
