A good non woven machine can produce good quality nonwoven fabrics. Like melt-blown nonwoven fabric, spunbond nonwoven farbic, spun-melt nonwoven fabric, etc. Melt-blown fabric has good filtration, shielding, heat insulation and oil absorption. Melt-blown fabric can be used in air, liquid filter materials, insulation materials, absorbent materials, mask materials, thermal insulation materials, oil absorbing materials and wipes and other fields.
The process of melt-blown fabric production: polymer feeding-melt extrusion-fiber formation-fiber cooling-forming web-reinforcing fabric.
Melt-blown fabirc application range
1. Medical and sanitary cloths: surgical gowns, protective clothing, disinfection wraps, masks, diapers, women's sanitary napkins, etc.;
2. Home decoration fabrics: wall coverings, tablecloths, bed sheets, bedspreads, etc.;
3. Clothing for clothing: lining, adhesive lining, flakes, shaping cotton, various synthetic leather base fabrics, etc.;
4. Industrial cloth: filter material, insulating material, cement packaging bag, geotextile, covering cloth, etc.;
5. Agricultural cloth: crop protection cloth, seedling raising cloth, irrigation cloth, thermal insulation curtain, etc.;
6. Others: space cotton, thermal insulation and sound insulation materials, linoleum felt, cigarette filters, tea bags in bags, etc.
What is the features of melt-blown nonwoven fabric?
1. Melt-blown nonwoven fabric mainly uses polypropylene as the main raw material, and the fiber diameter can reach 1~5 microns. Lots of voids, fluffy construction and good resistance to folding. These microfibers with unique capillary structure increase the number and specific surface area of fibers per unit area.
2. Melt-blown fabric has good filtering, shielding, heat insulation and oil absorption. It can be used in air, liquid filter materials, isolation materials, absorbent materials, mask materials, thermal insulation materials, oil absorbing materials and wipes.
3. The filter material is a kind of meltblown polypropylene microfibers randomly distributed knots together, white appearance, smooth, 0.5-1.0 material soft fiber denier, randomly distributed fibers provide more opportunities between fibers Thermal bonding.
4. Thus producing meltblown gas filter material with larger specific surface area and higher porosity (≥75%). After a very high pressure filtration efficiency, the product has low resistance, high efficiency, high dust holding capacity, etc.
What is the features of spunbond nonwoven fabric?
1. Lightweight: Polypropylene synthetic resin is used as the main raw material for production enterprises, with a specific gravity of only 0.9, which is only three-fifths of Chinese cotton, with fluffy and good hand feeling.
2. High comfort: It is formed by hot-melt bonding of thin fibers (2-3D) light spots, and the finished product has moderate softness and comfort.
3. Water repellent, breathable: Non-absorbent polypropylene chip, zero moisture, finished water side, made of 100% fibers with porous, breathable, easy maintenance dry cloth, easy to rinse.
4. Non-toxic and non-irritating: The performance is relatively stable, non-toxic, no peculiar smell, and does not irritate the skin.
5. Antibacterial and anti-chemical agents: Polypropylene is a chemically passive substance, not a moth, which can isolate the existence of bacteria and insect erosion in the liquid; antibacterial, alkali corrosion, and the finished product does not affect the erosion strength.
6. Antibacterial properties: Pull the products with water, mold, bacteria and insects and liquids can isolate the presence of erosion, mildew.
7. Environmental protection: The raw material of most non-woven fabrics is polypropylene, while the raw material of plastic bags is polyethylene. Although the names of the two substances are similar, the chemical structures are very different. The chemical molecular structure of polyethylene is quite stable and extremely difficult to degrade, so it takes 300 years for plastic bags to decompose; while the chemical structure of polypropylene is not strong, and the molecular chain is easily broken, so it can be effectively degraded and entered in a non-toxic form. In the next environmental cycle, a non-woven bag can be completely decomposed in 90 days. And the non-woven shopping bag can be reused more than 10 times, and the pollution to the environment after being wasted is only 10% of that of plastic bags.
