160cm White PP Meltblown Nonwoven Fabric For Medical And Sanitary

Basic introduction:

Melt-blown cloth is the core material of the mask. Medical masks and N95 masks are composed of spun-bond layer, melt-blown layer and spun-bond layer, where the spun-bond layer and melt-blown layer are both made of polypropylene PP material.

Applications:

(1)Medical and sanitary cloths: surgical gowns, protective clothing, sterile cloths, masks, diapers, women's sanitary napkins, etc.;

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

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

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

(5)Agricultural fabrics: crop protection fabrics, seedling raising fabrics, irrigation fabrics, thermal insulation curtains, etc.;

(6)Others: space cotton, thermal insulation and sound insulation materials, linoleum, cigarette filters, 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 fiber fineness of the material is 0.5-1.0 μm. The random distribution of fibers provides more thermal bonding between fibers, so that the melt-blown air filter material has a larger specific surface area and higher porosity (≥75%). After high-pressure electret filtration efficiency, the product has the characteristics of low resistance, high efficiency, high dust capacity and so on.

Main specifications:

Weight: 18g/m²-500g/m²

Trim width: 160cm, 180cm, 240cm or customized.

Technical process of melt-blown nonwovens:

Melt-blown cloth is the use of high-speed hot air flow to draw a thin stream of polymer melt extruded from the nozzle hole 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 main production process of melt-blown cloth:

1. Melt preparation

2. Filtering

3. Metering

4. The melt is extruded from the spinneret

5. Melt trickle drafting and cooling

6. Web-forming
