Advantages and disadvantages of non-woven medical consumables Shared by Medical non-woven consumable supplier.

Advantages:

1. Light weight: polypropylene resin as the main raw material of the medical non-woven fabric, proportion of only 0.9, only three fifths of cotton, fluffy, feel good.

2. Soft: composed of fine fiber (2-3D) light hot melt bonding molding. The finished product has moderate softness and comfort.

3. Water and air permeability: polypropylene slice does not absorb water and has zero moisture content. The finished product is of good water quality. It is composed of 100% fiber with porosity and good air permeability.

4. Non-toxic and non-irritating: the product is made of food grade raw materials in line with FDA, without other chemical ingredients, with stable performance, non-toxic, no peculiar smell and no skin irritation.

5. Antibacterial, anti-chemical agents: polypropylene is a chemical blunt material, no moth, and can isolate the existence of liquid bacteria and insect erosion; Antibacterial, alkali corrosion, finished products do not affect the strength due to erosion.

6. Antimicrobial properties. Products such as nonwoven Disposable Exam Paper Rolls with water extraction, mildewy, and can isolate the existence of liquid bacteria and insects erosion, mildewy moth.

7. Physical properties. The product is made of polypropylene spinning and directly spread into mesh thermal bonding. The strength of the product is better than that of general staple fiber products.

8. In terms of environmental protection, the raw material of most non-woven fabrics used is polypropylene, while the raw material of plastic bags is polyethylene. Although the names of the two substances are similar, they are far from each other in chemical structure. The chemical molecular structure of polyethylene is quite stable and difficult to degrade, so it takes 300 years to decompose plastic bags. The chemical structure of polypropylene is not strong, and the molecular chains can easily break, which can degrade effectively and enter the next environmental cycle in the non-toxic form. A non-woven shopping bag can be completely decomposed in 90 days. In addition, the non-woven shopping bag can be reused for more than 10 times, and the pollution to the environment after waste is only 10% of the plastic bag.

Disadvantages:

1) poor strength and durability compared with textile fabrics.

2) cannot be washed like other fabrics.

3) fibers are arranged in a certain direction, so they tend to split at right angles, etc. Therefore, the improvement of production methods mainly focuses on the improvement of preventing separation.
