Non-woven fabrics (English name: Non Woven Fabric or Nonwoven cloth), also known as non-woven fabrics, consist of oriented or random fibers. It is called cloth because of its cloth's appearance and certain properties.
Non-woven fabrics are moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic, non-irritating, colorful, low-cost, recyclable and so on. If more use of polypropylene (PP material) pellets as raw materials, the high temperature melting, spinning, shop outline, hot pressure coiling continuous one-step method of production.
Chinese name Non-woven fabric
Foreign name Non-woven fabric
Other name Non-woven, non-woven fabric
Materials Oriented or random fibers
    Non-woven fabrics do not have latitude and longitude lines, cutting and sewing are very convenient, and light and easy to shape, loved by hand-lovers.
    Because it is a kind of fabric that does not need spinning woven fabrics, but the textile short fibers or filaments are oriented or randomly arranged to form a web structure, and then reinforced by mechanical, thermal adhesive or chemical methods.
    Instead of being intertwined and braided together by a single yarn, the fibers are directly bonded together by physical means, so when you get the sticky name in your clothes, you will find that It is impossible to extract the root of a root. Non-woven fabrics break through the traditional textile principles, and have the characteristics of short process flow, fast production rate, high output, low cost, wide use, and many raw material sources.
The relationship between nonwovens and spunbonds
    Spunbonded fabrics and non-woven fabrics are affiliated. There are many production processes for the manufacture of nonwovens, of which spunbonding is one of the non-woven production processes.
Spunbonded nonwovens
(Including spunbonding, meltblowing, hot rolling, and hydroentanglement, most of the nonwovens currently produced in the market are spunbonded)
    Non-woven fabrics based on the composition, there are polyester, polypropylene, nylon, spandex, acrylic, etc.; different components will have different styles of non-woven fabrics. Spunbonded fabrics are usually referred to as polyester spunbonds and polypropylene spunbonds. The styles of these two fabrics are very close and can only be determined by high temperature testing.
    Non-woven fabric is a kind of non-woven fabric. It directly uses polymer chips, short fibers or filaments to wind the fibers through airflow or mechanical web, and then it is hydro-entangled, needle-punched, or hot-rolled and finally finished. Non-woven cloth formed. The new fiber products with a soft, breathable and planar structure have the advantage of not producing lint, strong, durable, silky and soft, but also a kind of reinforcing material, but also a cottony feel, compared with cotton, non-woven Cloth bag is easy to form and cheap.
1. Lightweight: polypropylene resin as the main raw material, the proportion is only 0.9, only cotton

 Three-fifths of it is bulky and feels good.
2. Soft: Consisting of fine fibers (2-3D) Light-point hot melt adhesive molding. The finished product is soft and comfortable.
3. Water-repellent, air-permeable: Polypropylene chips do not absorb water, water content is zero, finished product is water-repellent, composed of 100% fiber with porosity, good air permeability, easy to keep the fabric dry and easy to wash.
4. Non-toxic, non-irritant: The product is manufactured in compliance with FDA food grade raw materials, free of other chemical components, stable in performance, non-toxic, no odor, and does not irritate the skin.
5. Antibacterial and anti-chemical agents: Polypropylene is a chemically inert material, not insects, and can isolate the presence of bacteria and insects in the liquid; antibacterial, alkaline corrosion, the finished product will not affect the strength due to erosion.
6. Antibacterial. The product is water-removing, not moldy, and can isolate the bacteria and insects in the liquid.
7. Good physical properties. The direct spinning of polypropylene spinning is made by heat-bonding. The strength of the product is better than that of ordinary staple fiber products. The strength is non-directional and the strength in both vertical and horizontal directions is similar.
8. In terms of environmental protection, most of the raw materials used are polypropylene, and the plastic bag is made of polyethylene. Although the two materials have similar names, their chemical structures are quite different. The chemical molecular structure of polyethylene is quite stable and extremely difficult to degrade. Therefore, the plastic bag needs 300 years to be decomposed; while the chemical structure of polypropylene is not strong, the molecular chain can be easily broken and can be effectively degraded. , And in the non-toxic form into the next environmental cycle, 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 environmental pollution after disposal is only 10% of the plastic bags.
1) Poor strength and durability compared to woven fabrics.
2) It cannot be cleaned like other cloths.
3) The fibers are arranged in a certain direction, so it is easy to split from a right angle and so on. Therefore, improvements in production methods are mainly aimed at preventing the improvement of division.
