Product characteristics of nonwoven fabrics(2)

3. Water repellent and breathable: polypropylene slices do not absorb water, the water content is zero, the finished product has good water repellence, and it is composed of 100% fibers with porosity, good breathability, easy to keep the surface of the cloth dry and easy to wash.

4. can purify the air, using the advantages of small pores to keep bacteria and viruses out of the door.

5. Non-toxic, non-irritating: the product is produced with FDA food-grade raw materials, does not contain other chemical ingredients, stable performance, non-toxic, odorless, does not irritate the skin.

6. antibacterial, chemical resistance: polypropylene is a chemically blunt substance, not insects, and can isolate the presence of bacteria and insects within the liquid erosion; antibacterial, alkali corrosion, finished products do not affect the strength due to erosion.

7. Antibacterial properties: The product has the water pulling, not mold, and can isolate the existence of bacteria and insects in the liquid erosion, not mold moth.

8. Good physical properties: The strength of the product is better than the general staple fiber products, and the strength is non-directional, and the strength is similar in both vertical and horizontal directions.

9. In terms of environmental protection, the raw material of most of the non-woven fabrics used is polypropylene, while the raw material of plastic bags is polyethylene, although the names of the two substances are similar, but the chemical structure is very different. Polyethylene's chemical molecular structure has a fairly strong stability, extremely difficult to degrade, so plastic bags need 300 years to decompose; while the chemical structure of polypropylene is not strong, the molecular chain can easily break, which can be effectively degraded, and in a non-toxic form into the next step in the environmental cycle, a non-woven shopping bags in 90 days can be completely decomposed. And non-woven shopping bags can be reused more than 10 times, and the pollution of the environment after disposal is only 10% of plastic bags.

Disadvantages.

1. Compared with textile fabric strength and durability is poor.

2. Can not be cleaned like other fabrics.

3. The fibers are arranged in a certain direction, so it is easy to split from the right angle direction, etc. Therefore, the improvement of the production method is mainly focused on the improvement of the prevention of splitting.
