Do you know how long the polypropylene nonwoven can decompose? The non-woven fabric made of virgin polypropylene is generally used for a period of one year. This is no problem.

And PP non woven fabrics have the following characteristics:

1. Light weight: Polypropylene is used as the raw material, and its specific gravity is only 0.9. Only three-fifths of cotton has a fluffy texture and feels good.

2. Soft: Consisting of fine fibers (2-3D) Light-point hot melt adhesive type. The finished product is soft and comfortable.

3. Water repellent, air permeability: Polypropylene chips do not absorb water, water content is zero, finished product has good water repellency, composed of 100% fiber with porosity, good air permeability, easy to keep the fabric dry and easy to wash.

4. Non-toxic, non-irritating: The product is produced in accordance with PP raw materials, does not contain other chemical components, has stable performance, is non-toxic, has no odor, and does not irritate the skin.

5. Antibacterial, anti-chemical agents: Polypropylene is a chemical blunt substance, not insects, and can isolate the presence of bacteria and insects in the liquid erosion; antibacterial, alkaline corrosion, the finished product will not affect the strength due to erosion.

6. Antibacterial property: The product has water repellency, no mildew, and it can isolate the bacteria and insects in the liquid.

7. Good physical property: It is made by direct spinning of polypropylene spinning into a net and heat bonding. The strength of the product is better than that of ordinary staple fiber products. The strength is not directional, and the strength in both vertical and horizontal directions is similar.

8. In terms of environmental protection, most of the non-woven fabrics used are made of polypropylene, while the plastic bags are made of polyethylene. Although the two materials have similar names, they differ in chemical structure. The chemical molecular structure of polyethylene is quite stable and extremely difficult to degrade. Therefore, the plastic bag needs 300 years to be decomposed; while the chemical structure of polypropylene is not strong, the molecular chain can be easily broken and can be effectively degraded. , And in the non-toxic form into the next environmental cycle, the degree of pollution of the environment after the disposal of only 10% of plastic bags.

After understanding the above, you should know the decomposition period of polypropylene nonwovens. For more information, please follow us.
