PP Non Woven Fabric
Do you know the advantages and disadvantages of non woven mask fabrics?
Nov , 05 2020

Non woven fabric, also known as non-woven fabric, is composed of oriented or random fibers to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical methods.

Foshan Guide Textile Co., Ltd. has been focusing on the production of spunbonded non woven fabrics for more than ten years, which are widely used in medical, furniture, packaging, agriculture and other fields. In the medical field, it is often used to make disposable masks, hoods, protective clothing, shoe covers, disposable sheets, etc. There are two kinds of non woven fabrics for masks. The outer layer and the inner layer are spunbonded non woven fabrics, and the middle layer is melt-blown non woven fabrics. The raw materials for the production of both non woven fabrics are polypropylene, also called polypropylene (PP).

Advantages of non woven fabric

Lightweight, with polypropylene resin as the main raw material, the specific gravity is only 0.9, only three-fifths of cotton. It is fluffy and feels good.

It is soft, composed of fine fibers (2-3D) and formed by light-point hot melt bonding. The finished product is moderately soft and comfortable

Water repellent, breathable, polypropylene slices do not absorb water, have zero moisture content, and the finished product has good water repellency. It is composed of 100% fiber and has good air permeability. It is easy to keep the cloth dry and easy to wash.

It is non-toxic and non-irritating. The product is produced with FDA food-grade raw materials, does not contain other chemical components, has stable performance, is non-toxic, non-odor, and does not irritate the skin.

Antibacterial and anti-chemical agents, polypropylene is a chemically blunt substance, not moth-eaten, and can isolate the corrosion of bacteria and insects in the liquid; antibacterial, alkali corrosion, and the strength of the finished product will not be affected by erosion.

Good physical properties. It is made of polypropylene spun yarn directly laid into a net and thermally bonded. The strength of the product is better than that of ordinary staple fiber products. The strength is non-directional, and the strength is similar in the vertical and horizontal directions.

Environmental protection. 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 quite different in chemical structure. The chemical molecular structure of polyethylene is very stable and extremely difficult to decompose, so it takes 300 years for plastic bags to be decomposed; while the chemical structure of polypropylene is not strong, the molecular chain can easily be broken, which 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, the non-woven shopping bag can be reused more than 10 times, and the pollution to the environment after being discarded is only 10% of the plastic bag.

Disadvantages of non woven fabrics

Compared with woven fabrics, it has poor strength and durability and cannot be cleaned like other fabrics. Therefore, the masks we usually use cannot be washed and reused. The fibers are arranged in a certain direction, so it is easy to split from the right angle direction and so on. Therefore, the improvement of the production method mainly focuses on the improvement of preventing splitting.
