Non-woven fabric - China's non-woven fabric development status and prospects

In recent years, China's non-woven fabric industry has developed rapidly, and its production and sales have achieved rapid growth. However, some problems have arisen in the development process, such as low mechanization rate and slow industrialization. The reasons are many, except for the management system. In addition to the marketing factors, the technical strength is weak, and the lack of basic research is a major obstacle. Although it has accumulated rich production experience in recent years, it has not been theoreticalized, and it is difficult to guide mechanized production.

The number of infrastructure projects in China continues to increase. These projects require a large amount of geotextiles, filter materials, waterproof materials, and packaging materials. In addition, the increase in domestic consumer income will also effectively promote the consumption of various sanitary absorbent products and air filtration materials, medical and hygiene products and labor insurance and sports supplies. Therefore, China's non-woven fabric industry has great growth potential in the future. [1]

Material characteristics 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 finally A non-woven fabric formed by finishing. The new fiber product with soft, breathable and flat structure has the advantages of no lint, strong, durable, silky softness, and a cottony feel. Compared with cotton, the non-woven bag is easy to form, and The cost is cheap.

Non-woven fabric features: durability, disposable. Insulated, conductive. Softness, stiffness. Fineness, swelling. Isotropic, anisotropic. Filterable, breathable and impervious. Elasticity, stiffness. Light, loose, warm. Thin as a flap, thick as a felt. Waterproof and moisture permeable. Ironed, stitched, molded. Flame retardant, antistatic. Water permeable, waterproof, abrasion resistant, and napped. Resistant to wrinkles, good elasticity, high moisture absorption, water repellency.
1. Light weight: Polypropylene resin is the main raw material for production. The specific gravity is only 0.9, only three-fifths of cotton is fluffy and feels good.
2. Soft: Made of fine fiber (2-3D) light-point hot melt bonding. The finished product is moderately soft and comfortable.
3. Water and air permeability: polypropylene chips do not absorb water, the water content is zero, the finished product has good water repellency, and it is composed of 100% fiber with porosity, good gas permeability, easy to keep the cloth surface dry and easy to wash.
4. Non-toxic, non-irritating: The product is produced in accordance with FDA food-grade raw materials, does not contain other chemical components, has stable performance, is non-toxic, has no odor, and does not irritate the skin.
5. Antibacterial and anti-chemical agents: Polypropylene is a chemically blunt substance, which is free of insects and can isolate the bacteria and insects in the liquid. Antibacterial, alkali corrosion and finished products do not affect the strength due to erosion.
6, antibacterial. The product has water-extracting properties, is not moldy, and can isolate the 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, most of the raw materials used in the current non-woven fabrics are polypropylene, and the raw material of the plastic bags is polyethylene. Although the two substances have similar names, they have far different chemical structures. 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 can be easily broken, so that it 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, the non-woven shopping bag can be reused more than 10 times, and the environmental pollution degree after disposal is only 10% of the plastic bag.

weakness is:

1) Poor strength and durability compared to woven fabric

2) Can't be washed like other fabrics

3) The fibers are arranged in a certain direction, so they are easily split from a right angle direction and the like. Therefore, the recent improvement in production methods has mainly focused on preventing the improvement of division.

The main purpose:
(1) Medical and sanitary non-woven fabrics: surgical gowns, protective clothing, disinfecting wraps, masks, diapers, civilian rags, wipes, wet wipes, magic towels, soft towel rolls, beauty products, sanitary napkins, sanitary care Pads, disposable sanitary napkins, etc.;
(2) Non-woven fabrics for court decoration: wall coverings, tablecloths, bed sheets, bedspreads, etc.;
(3) Non-woven fabrics for clothing: lining, adhesive lining, flakes, styling cotton, various synthetic leather base fabrics, etc.;
(4) Industrial non-woven fabrics; base materials for roofing waterproofing membranes and asphalt shingles, reinforcing materials, polishing materials, filter materials, insulating materials, cement packaging bags, geotextiles, coated fabrics, etc.;
(5) Non-woven fabrics for agriculture: crop protection cloth, nursery cloth, irrigation cloth, heat preservation curtain, etc.;
(6) Other non-woven fabrics: space cotton, thermal insulation material, oil absorbing felt, smoke filter, bag tea bag, shoe material, etc.
