Melt-blown cloth is mainly made of polypropylene as the main raw material, the fiber diameter can reach 1 ~ 5 microns. With many voids, fluffy structure and good anti-folding ability, these microfibers with unique capillary structure increase the number and surface area of fibers per unit area, so that melt-blown cloth has good filter, shielding, insulation and oil absorption. It can be used for air and liquid filtration materials, isolation materials, absorbing materials, mask materials, warm materials, oil absorbing materials and wiping cloth and other fields.
Scope of application:
(1) Medical and health cloth: operating clothes, protective clothing, disinfectant cloth, masks, diapers, women's sanitary napkins, etc.;
(2) Home decoration cloth: wall cloth, tablecloth, bed sheet, bedspread, etc.;
(3) Cloth for heel mounting: lining, adhesive lining, floc, shaping cotton, various synthetic leather sole cloth, etc.;
(4) Industrial cloth: filter materials, insulation materials, cement packaging bags, geotextiles, covering cloth, etc.;
(5) Agricultural cloth: crop protection cloth, seedling raising cloth, irrigation cloth, insulation curtain, etc.;
(6) Others: space cotton, insulation and sound insulation materials, linoleum, smoke filter, tea bag, etc.
Meltblowout cloth filter material is made of polypropylene microfiber randomly distributed stick together, white, smooth, soft appearance, material fiber size is 0.5-1.0μm, the random distribution of fibers provides more opportunities for thermal adhesion between fibers, so that meltblowout gas filter material has a larger specific surface area, higher porosity (≥75%). Through high voltage electret filtration efficiency, the product has the characteristics of low resistance, high efficiency and high dust tolerance.
Non-woven Fabric (English name: Non Woven Fabric or Nonwoven cloth), also known as nonwoven fabric, is composed of oriented or random fibers. It is called cloth because it has the appearance and certain properties of cloth.
Non-woven fabric is moisture-proof, breathable, flexible, light weight, non-combustion-supporting, easy to decompose, non-toxic and non-irritating, rich color, low price, recyclable and other characteristics. Such as polypropylene (pp material) as raw materials, through high temperature melting, wire spraying, laying, hot roll continuous step production.
Features of non-woven fabric:
Non-woven fabric has no warp and weft, cutting and sewing are very convenient, and light and easy to shape, deeply loved by manual enthusiasts. This is because it is a kind of fabric that does not need spinning and weaving. It is just oriented or randomly arranged textile short fibers or long filaments to form a fiber network structure, and then reinforced by mechanical, thermal adhesive or chemical methods.
Instead of being interwoven and braided one by one, the fibers are physically glued together, so that when you reach the scale in your clothes, you will find that you cannot pull out the threads. Nonwovens break through the traditional textile principle, and has the characteristics of short process, fast production rate, high yield, low cost, wide use, multiple raw material sources and so on.
The relationship between non-woven fabric and spunbonded fabric
Spunbonded cloth and non - woven fabric is dependent. There are many production processes for the manufacture of non-woven fabrics, among which spunbond method is one of the production processes of non-woven fabrics (including spunbond method, meltblow method, hot rolling method, spunthorn method, currently most of the non-woven fabrics on the market are produced by spunbond method).
Non-woven fabric according to the composition, polyester, polypropylene, nylon, spandex, acrylic and so on; Different components will have completely different styles of non-woven fabric. And spunbonded cloth, usually refers to polyester spunbonded, polypropylene spunbonded cloth; And the styles of the two cloths are so close that they can only be identified by high temperature tests.
Nonwoven fabric is a kind of nonwoven fabric, it is the direct use of polymer slices, short fibers or filament fibers through the air flow or mechanical net, and then through the water thorn, needle, or hot rolled reinforcement, and finally after finishing the formation of non-woven fabric. With soft, breathable and flat structure of the new fiber products, the advantages are no fiber chips, strong, durable, silky soft, is also a kind of reinforcing material, but also the feeling of cotton, and cotton fabrics, non-woven bags are easy to form, and the cost of cheap.
Advantages:
1. Light weight: With polypropylene resin as the main raw material, the proportion is only 0.9, only three-fifths of cotton, fluffy, feel good.
2. Soft: Composed of fine fibers (2-3D) light point hot melt bond molding. The finished product has moderate softness and comfortable feeling.
3. Water, breathable: polypropylene slice does not absorb water, water content is zero, the finished product is good water, composed of 100% fiber with porous, good air permeability, easy to keep the cloth dry, easy to wash.
4. Non-toxic and non-irritating: The product is made of FDA food grade raw materials, does not contain other chemical components, stable performance, non-toxic, no odor, does not irritate the skin.
5. Anti-bacterial, anti-chemical agents: polypropylene
