Meltblown cloth is the core material of the mask. It mainly uses polypropylene as the main raw material, and the fiber diameter can reach 1 to 5 microns. There are many voids, fluffy structure, and good fold resistance. The ultrafine fibers with unique capillary structure increase the number and surface area of fibers per unit area, so that the melt-blown cloth has good filterability, shielding, heat insulation, and oil absorption. It can be used in the fields of air, liquid filtration materials, insulation materials, absorption materials, mask materials, thermal insulation materials, oil-absorbing materials and wipers.

Application range

(1) Medical and sanitary cloths: surgical gowns, protective clothing, sterilization wraps, masks, diapers, sanitary napkins, etc.;

(2) Fabrics for home decoration: wall stickers, tablecloths, bed sheets, bed covers, etc.;

(3) Cloth for clothing: lining, adhesive lining, flakes, shaped cotton, various synthetic leather backings, etc.;

(4) Industrial fabrics: filter materials, insulating materials, cement bags, geotextiles, covering fabrics, etc.;

(5) Agricultural cloth: crop protection cloth, nursery cloth, irrigation cloth, thermal insulation curtain, etc.;

(6) Others: space cotton, thermal insulation and sound insulation materials, linoleum, cigarette filter, tea bags, etc.

The melt-blown filter material is made of polypropylene microfibers randomly distributed and bound together. The appearance is white, smooth and soft. The material fiber fineness is 0.5-1.0μm. The random distribution of fibers provides more thermal bonding between fibers Chance, so that the melt-blown gas filter material has a larger specific surface area and a higher porosity (≥75%). After high-pressure electret filtration efficiency, the product has the characteristics of low resistance, high efficiency and high dust capacity.

Main specifications

Weight: 18g-500g

Wide width: generally 160cm and 180cm (can also be determined according to customer needs)

Melt-blown fabric is a high-speed hot air flow to draw a thin stream of polymer melt extruded from the die orifice of the die, thereby forming ultra-fine fibers and collecting them on the condensed screen or roller, and at the same time bonding themselves to become Meltblown nonwoven fabric.

The production process of meltblown cloth is mainly as follows:

　　 1. Melt preparation

　　 2. Filtration

　　 3. Measurement

　　 4. The melt is extruded from the spinneret

　　 5. Melt trickle drafting and cooling

　　 6. Netting

Product Usage

Meltblown fabrics use polypropylene as the main raw material, and the fiber diameter can reach 0.5-10 microns. These ultrafine fibers with unique capillary structure increase the number and surface area of fibers per unit area, thereby making the meltblown fabrics have good air filtration properties. It is a good mask material. In large, medium and small medical institutions, in earthquake- and flood-affected areas, during the high season of SARS, avian influenza and H1N1 virus, melt-blown filter paper plays an irreplaceable role with its strong filtering performance effect.

The main use of meltblown cloth:

　　 1. Filter material

　　 2. Medical and health materials

　　 3. Environmental protection materials

　　 4. Clothing materials

　　 5. Battery separator material

　　 6. Wiping materials
