What is meltblown fabric? What is the difference between meltblown fabric and nonwoven fabric?

What is meltblown fabric? The main raw material of meltblown fabric is polypropylene, the diameter of which is up to 1~5 microns. Large gap, fluffy structure, good folding resistance. This special microfiber has a unique microstructure, increasing the number of fibers per unit area and specific surface area.

Meltblown fabric has good performance of filtration, shielding, heat insulation and oil absorption. It is suitable for air and liquid filtration materials, isolating agent, absorbent, mask material, heating agent, oil absorbent, rags and other fields.

Processing technology of hot melt cloth: polymer-melt extrusion-fiber formation-fiber cooling-netting-binding force.

The scope of use is melting cloth:

Medical and health supplies: surgical gowns, protective gowns, sterilized wraps, face masks, diapers, women's sanitary napkins and so on;

Home decoration: wallpapering, tablecloths, bed sheets, bedspreads, etc;

Materials: lining, interlining, wadding, shaping cotton, various synthetic leather backing, etc;

Industrial products: filter material, insulating material, cement packing bag, geotextile, wrapping cloth, etc;

Agricultural cloths: protective cloths, nursery cloths, irrigation cloths, heat-insulating curtains, etc;

Others: space cotton, heat and sound insulation materials, oil-absorbing felt, cigarette holders, tea bags, etc.

What is the difference between hot melt fabric and non-woven insulation bag?

The main raw material of meltblown fabric is polypropylene with a diameter of 1~5 microns. The gap is large, the structure is fluffy, and the anti-folding performance is good. This special microfiber has a unique microstructure, increasing the number of fibers per unit area and specific surface area.

Meltblown fabric has good filtration, shielding, heat insulation and oil absorption properties. It is suitable for air and liquid filtration materials, isolators, absorbents, mask materials, heating agents, oil absorbents, wipes and other fields.

The filter material is randomly distributed as meltblown polypropylene microfiber filaments, white, smooth surface, 0.5-1.0 material of soft fibers, the irregular distribution of fibers provides more opportunities for thermal bonding.

Therefore, the meltblown gas filtration material has a large specific surface and high porosity (greater than 75%). After high pressure of filtration efficiency, the product has low resistance, high efficiency and high dust capacity.

NonWoven Fabric or Nonwovencloth, which consists of directional or irregular fibers. It is called cloth because of its appearance and certain product properties.

It is characterized by moisture resistance, breathability, good elasticity, light weight, non-combustible, easily decomposable, non-toxic, non-irritating, colorful, inexpensive, recyclable... such as polypropylene (pp material) particles as raw materials, through high-temperature melting, silk spraying, laying, rolling continuous production.

Nonwoven features:

Does not need warp and weft, cutting, sewing are very convenient, and light weight, easy to shape, like to use their hands.

Because it is a fabric that does not need to be spun, only need to analyze the direction or irregular arrangement, it can form a fiber network structure, so we use traditional mechanical, thermal bonding or chemical reinforcement.

With gauze is not interwoven, but the fibers are connected directly by physical means. Therefore, when you get the name stuck to your clothes, you will find that it cannot be pulled out. It breaks through the traditional textile principle of short process, fast production speed, high yield, low cost, versatility and wide source of raw materials.
