Melt-blown fabric
Meltblown cloth is the core material of the mask. Meltblown cloth is mainly made of polypropylene and its fiber diameter can reach 1 to 5 microns. The super xi fiber with unique te capillary structure increases the number and surface area of the fiber per unit area, so that the meltblown cloth has good filtration, shielding, thermal insulation and oil absorption. It can be used in air and liquid filter material, isolation material, absorption material, mask material, heat preservation material, oil absorption material and wiping cloth and other fields.
Melt spray cloth is the core material of the mask. YONG masks and N95 masks are composed of a spunbonded layer, a meltblown layer and a spunbonded layer, in which the spunbonded layer and meltblown layer are composed of polypropylene PP material
Meltblown cloth filter material is made of polypropylene super Xi fiber randomly distributed and bonded together, the appearance is white, smooth and soft, the fiber fineness of the material is 0.5-1.0μm, the random distribution of fibers provides more opportunities for thermal bonding between the fibers, so that the meltblown gas filter material has a larger specific surface area, higher porosity (≥75%). Through the high voltage electret filtration efficiency, the product has the characteristics of low resistance, high Xiao, high dust tolerance and so on.
Extended Information:
Non-toxic and tasteless, highly effective bacteria-proof. Through the special treatment of the equipment, it can achieve the properties of antistatic, anti-alcohol, anti-plasma, water-repellant and water-producing.
Features of non-woven fabric: durability, disposable. Insulating, conducting electricity. Flexibility, stiffness. Fineness, expansibility. Anisotropy, anisotropy. Filterability, breathable and waterproof. Flexibility, rigidity. Light, loose, warm. Thin as a cicada and thick as a felt.
Water proof and permeable to moisture. Ironing, stitching, moulding. Flame retardant and antistatic. Permeable, waterproof, wear-resistant and fleecy. Wrinkle resistance, good elasticity, high moisture absorption, water repellent.
1. Light quality: polypropylene resin as the main raw material, specific gravity is only 0.9, only three fifths of cotton, with fluffiness, good hand feel.
2. Soft: composed of fine fibers (2-3D), light point hot melt bonding forming. The finished product has moderate softness and comfort.
3. Water and air permeability: polypropylene slice does not absorb water, water content is zero, the finished product water quality is good, composed of 100% fiber with porosity, good air permeability, easy to keep the cloth dry, easy to wash.
4. Non-toxic, non-irritating: the product is made of food grade raw materials in line with FDA, without other chemical ingredients, stable performance, non-toxic, no odor, and no irritation to the skin.
5. Antimicrobial and chemical resistance: polypropylene is a chemically blunt material, not moth-eaten, and can isolate bacteria and insect erosion in the liquid; Antibacterial, alkali corrosion, the finished product does not affect the strength due to erosion.
Melt blown cloth is mainly polypropylene as the main raw material, in addition to contain a small amount of polyurethane and polylactic acid, has a good thermal insulation, but will also burn at high temperature.
Disposable medical masks with virus protection effect generally have three layers. Its core raw material is the middle layer made of polypropylene melt-blown cloth, which is also the key layer for the virus protection effect of disposable masks. Disposable medical masks with real virus protection effect, remove the middle layer, burn with a lighter, it can not burn, in professional terms is the melt-blown cloth after ignition for melting effect, generally will not produce flame.
