Basic Knowledge About Non-woven Farbic

Non-woven fabric, also known as Non-Woven Fabric or Non-woven cloth, is composed of directional or random fibers. It is a new generation of environmentally friendly materials. It is moisture-proof, breathable, flexible, lightweight, non-combustible, and easy to decompose. Non-toxic and non-irritating, rich in color, low price, recyclable, and so on. For example, polypropylene (pp material) pellets are used as raw materials and are produced by a continuous one-step method of high-temperature melting, spinning, laying, and hot pressing and coiling. It is called cloth because of its appearance and certain properties.

The non-woven fabric has no warp and weft threads, so it is very convenient to cut and sew, and it is light and easy to shape. Because it is a kind of fabric that does not need spinning and weaving, it just orients or randomly arranges textile staple fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal bonding, or chemical methods.

It is not interwoven and braided by yarns one by one, but the fibers are directly bonded together by physical methods, so when you get the sticky scale in your clothes, you will find that You can't get a single thread out. Nonwovens break through the traditional textile principles and have the characteristics of short process flow, fast production rate, high output, low cost, wide application, and many sources of raw materials.

Advantages of non-woven fabric

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

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

3. Water repellency and breathability: Polypropylene chips do not absorb water, have zero moisture content, and the finished product has good water repellency. It is composed of 100% fiber, which is porous and has good air permeability. It is easy to keep the cloth surface dry and easy to wash.

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

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

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

7. Good physical properties. It is made of polypropylene spun directly into a mesh and thermally bonded. The strength of the product is better than that of ordinary staple fiber products. The strength is non-directional, and the vertical and horizontal strengths are similar.

8. 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 two substances have similar names, they are very different in chemical structure. The chemical molecular structure of polyethylene has strong stability and is extremely difficult to degrade, so it takes 300 years for plastic bags to decompose; while the chemical structure of polypropylene is not strong, 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 bags can be reused more than 10 times, and the pollution to the environment after disposal is only 10% of that of plastic bags.
