When it comes to non-woven bags, everyone is familiar with them. What kind of fabric is it made of? Of course it is non-woven fabric. So what are the characteristics of non-woven fabric? Today, the editor will talk to you about the advantages and disadvantages of non-woven fabrics!

Advantages of non-woven fabrics:

1. Lightweight: Polypropylene resin is used as the main production raw material, with a specific gravity of only 0.9, only three-fifths of cotton, fluffy and good feel.

2. Soft: It is composed of fine fibers (2-3D) and lightly hot-melt-bonded. The finished product is moderately soft and comfortable.

3. Water-repellent and breathable: Polypropylene slices do not absorb water, with zero moisture content. The finished product has good water repellency. It is composed of 100% fibers with porosity and good breathability. It is easy to keep the cloth dry and easy to wash.

4. Non-toxic and non-irritating: The product is produced with FDA food-grade raw materials, does not contain other chemical ingredients, has stable performance, is non-toxic, has no odor, and does not irritate the skin.

5. Antibacterial and anti-chemical agent: Polypropylene is a chemically blunt substance, not moth-eaten, and can isolate the erosion of bacteria and insects in the liquid; antibacterial, alkali corrosion, the finished product does not affect the strength due to erosion.

6. Antibacterial. The product is water-repellent, not moldy, and can isolate the erosion of bacteria and insects in the liquid, and is not moldy.

7. Good physical properties. It is made of polypropylene spinning directly into a net and hot-bonded. The strength of the product is better than that of general short fiber products. The strength is non-directional and the longitudinal and transverse strengths are similar.

8. In terms of environmental protection, the raw material of most non-woven fabrics used is polypropylene, and the raw material of plastic bags is polyethylene. Although the two substances have similar names, they are very different in chemical structure. The chemical molecular structure of polyethylene has a very strong stability and is extremely difficult to degrade, so it takes 300 years for plastic bags to decompose completely; while the chemical structure of polypropylene is not strong, and the molecular chain can be easily broken, so it can be effectively degraded and enter the next environmental cycle in a non-toxic form. A non-woven shopping bag can be completely decomposed within 90 days. Moreover, Non-woven Shopping Bag can be reused more than 10 times, and the pollution to the environment after disposal is only 10% of that of plastic bags.

Disadvantages of non-woven fabrics:

1) Poor strength and durability compared to woven fabrics.

2) Cannot be washed like other fabrics.

3) Fibers are arranged in a certain direction, so they are easy to split at right angles, etc. Therefore, the improvement of production methods is mainly focused on improving the prevention of splitting.
