Non-woven fabric has no warp and weft thread, it is very convenient to cut and sew, and it is light and easy to set.

Because it is a kind of fabric that does not need to be spun and woven, it is only the textile staple fiber or filament is carried on the direction or the random arrangement, forms the fiber network structure, then USES the mechanical, the hot stick or the chemical method and so on reinforcement becomes.

It is not woven and knotted together from yarn to yarn, but the fibres are glued together directly by physical means, so that when you get the scale in your clothes, you will find that there is no thread to pull out. Nonwoven fabric has broken through the traditional textile principle, and has the characteristics of short technological process, fast production rate, high output, low cost, wide use and many raw material sources.
The relationship between non-woven and spunbonded fabrics

According to the composition of non-woven fabric, there are polyester, polypropylene, polyamide, spandex, acrylic and so on; Different ingredients will have distinct non-woven styles. And spunbonded cloth, usually refers to polyester spunbonded, polypropylene spunbonded; The styles of the two cloths are so close that they can only be identified by a high temperature test.
Nonwoven fabric is a nonwoven fabric, which is woven directly by using polymer slices, staple fibers or filament fibers to form a mesh through air flow or machinery, then through spining, needling, or hot rolling reinforcement, and finally after finishing. Soft, breathable and flat structure of the new fiber products, the advantage is no fiber chips, strong, durable, silky soft, is also a kind of reinforcement materials, and there is a feeling of cotton, compared with cotton, non-woven bags easy to form, and cheap cost.

Advantages:

1. Light weight: polypropylene resin as the main production material, the proportion of only 0.9, only three-fifths of the cotton, with fluffy, feel good.
2. Soft: made of fine fibers (2-3D), lightly formed by hot fusion bonding. The finished product has moderate softness and comfort.

3. Water allocation, breathable: polypropylene slice does not absorb water, moisture content is zero, the finished product water allocation is good, composed of 100% fiber porous, good permeability, easy to keep the cloth surface dry, easy to wash. Polypropylene nonwoven

4. Non-toxic and non-irritating: the product is produced from food grade raw materials in accordance with the FDA, without other chemical ingredients, stable performance, non-toxic, no odor, no irritation to the skin.

5. Antibacterial, anti-chemical agents: polypropylene is a chemical blunt substance, not moth, and can isolate the presence of bacteria and insect erosion in the liquid; Antibacterial, alkali corrosion, finished products do not affect the strength due to erosion.

6. Antimicrobial properties. Products with water, no mold, and can isolate the presence of bacteria and insects in the liquid erosion, no mold.

7. Physical properties. The product is made of polypropylene spinning, which is directly spread into a net and bonded with heat.

8. In terms of environmental protection, most non-woven fabrics are made from polypropylene, while plastic bags are made from polyethylene, two materials with similar names but far different chemical structures. The chemical molecular structure of polyethylene has quite strong stability and is extremely difficult to degrade, so plastic bags need 300 years to complete the decomposition; The chemical structure of polypropylene is not strong, the molecular chain can be easily broken, which can be effectively degraded, and in a non-toxic form into the next environmental cycle, a non-woven shopping bag can be completely broken down in 90 days. Moreover, non-woven shopping bags can be reused for more than 10 times, and the pollution to the environment is only 10% of that of plastic bags.

Disadvantages:
1) poor strength and durability compared with textile cloth.

2) it cannot be washed like other fabrics.

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