Non-woven fabrics (English name: Non Woven Fabric or Nonwoven cloth), also known as non-woven fabrics, are composed of oriented or random fibers. It is called a cloth because it has the appearance and some functions of the cloth.

The non-woven fabric has the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, simple decomposition, non-toxic and non-influential, rich in color, low in price, and recyclable. For example, polypropylene (pp material) pellets are used as materials, which are produced by high-temperature melting, spinning, paving, and hot-pressing.

Features:

The non-woven fabric has no latitude and longitude lines, is very convenient for cutting and sewing, and is light and simple to shape, which is very popular among art lovers. Because it is a fabric that does not require spinning woven fabric, only the woven short fibers or filaments are oriented or randomly arranged to form a web structure, and then reinforced by mechanical, thermal bonding or chemical methods. Instead of interlacing and braiding the yarns one by one, the fibers are bonded directly together by physical means, so when you get the sticky name in your clothes, you will find that It is impossible to draw a single thread. Nonwoven fabric breaks through the traditional textile principle, and has the characteristics of short process flow, fast production rate, high output value, low cost, wide use and rich material history.

The relationship between non-woven fabric and spunbond fabric:

Spunbond and non-woven fabrics are affiliation. There are many production processes for the manufacture of non-woven fabrics, among which the spunbonding method is one of the non-woven fabric production process spunbonded nonwoven fabrics (including spunbonding, meltblowing, hot rolling, hydroentangling, now Most of the non-woven fabrics produced by the spunbond method in the market are non-woven fabrics, such as polyester, polypropylene, nylon, spandex, acrylic, etc.; different ingredients will have different nonwoven fabric styles. The spunbonded cloth generally refers to polyester spunbond and polypropylene spunbond; and the styles of the two fabrics are very close, which can be discerned by high temperature test. Non-woven fabric is a kind of non-woven fabric, which directly uses high polymer chips, short fibers or filaments to pass the fibers through airflow or mechanical netting, and then through hydroentanglement, needle punching, or hot rolling reinforcement, and then through Finish the composition of the non-woven fabric. A new type of fiber product with soft, breathable and flat structure, the strength is no lint, strong, smooth, silky soft, also a kind of reinforcing material, and also a cotton feeling, compared with cotton, non-woven The cloth bag is simply formed and inexpensive to manufacture.

Strengths:

1. Light weight: Polypropylene resin is the primary production material, the specific gravity is only 0.9, as long as cotton non-woven products (3 sheets) three-fifths, fluffy, feel good.

2. Soft: Made of fine fibers (2-3D), light-point hot melt bonding. The product is soft and comfortable.

3. Water-repellent, breathable: polypropylene slices do not absorb water, water content is zero, the product water-repellent is good, composed of 100% fiber with porosity, good gas permeability, easy to keep the cloth dry and easy to wash.

4. Non-toxic, non-influence: The product is selected to meet the FDA food grade material production, does not contain other chemical components, stable in function, non-toxic, no odor, does not affect the skin.

5. Antibacterial and anti-chemical agents: Polypropylene is a chemically blunt substance, which does not worm, and can block the corrosion of bacteria and insects in liquids; antibacterial, alkali corrosion, and products do not affect the strength due to corrosion.

6. Antibacterial. The product has water-extracting properties, is not moldy, and can block the corrosion of bacteria and insects in the liquid, and is not mildewed.

7. Good physical properties. It is made by directly spinning polypropylene into a mesh, and the strength of the product is better than that of the general staple fiber product, the strength is non-directional, and the longitudinal and transverse strengths are similar.

8. In terms of environmental protection, the raw material of most non-woven fabrics used is polypropylene, and the raw material of plastic bags is polyethylene. Although the two substances are similar in name, they are far from chemically different. The chemical molecular structure of polyethylene has considerable stability and is extremely difficult to degrade. Therefore, it takes 300 years for the plastic bag to be decomposed. The chemical structure of polypropylene is not strong, and the molecular chain is simple to crack, so that it can be effectively degraded. And enter the next environmental cycle in a non-toxic shape, a non-woven shopping bag can be decomposed within 90 days. And the non-woven shopping bag can be reused more than 10 times, and the environmental pollution degree after abandonment is only 10% of the plastic bag.

Defects: 1) Poor strength and durability compared to woven fabrics.

2) Can't be washed like other fabrics.

3) The fibers are arranged in a certain direction, so they are simply split from a right angle direction and the like. Therefore, the improvement of the production method is mainly to prevent the improvement of the split.

Maintenance of non-woven fabrics:

The following points should be noted in the maintenance and collection of non-woven fabrics:

1, to keep clean, often change to prevent mites breeding.

2. When storing in season, it must be washed, ironed and dried to be sealed in a plastic bag and placed flat in the closet. Pay attention to shading to prevent fading. It should be ventilated, dedusted and dehumidified, and exposed to the sun. Anti-mold and anti-mite tablets should be placed in the closet to prevent the cashmere products from being affected by moisture and mildew.

3, the inner garment lining should be lubricated when it is worn inside, and the hard object such as pen, key bag, mobile phone, etc. should be avoided in the pocket to avoid partial friction and pilling. Try to reduce friction with hard objects (such as sofa backs, armrests, table tops) and hooks when wearing them. It is not easy to wear for too long. It must be stopped or replaced in about 5 days to restore the elasticity of the clothes and avoid fiber fatigue damage.

4, if there is pilling, do not pull, you must use scissors to cut the pomp, to avoid the formation of the line can not be repaired.
