What is Spunbond non-woven fabric and What is the difference between it and Melt-blown fabric

What is Spunbond non-woven fabric and What is the difference between it and Melt-blown fabric

(Summary description)Spunbond non-woven fabric is extruded and stretched polymer to form continuous filaments, and the filaments are laid into a net. The fiber net is then bonded by itself, thermally bonded, chemically bonded or mechanically reinforced to make the fiber net It becomes a non-woven fabric.

Information

Spunbond non-woven fabric is extruded and stretched polymer to form continuous filaments, and the filaments are laid into a net. The fiber net is then bonded by itself, thermally bonded, chemically bonded or mechanically reinforced to make the fiber net It becomes a non-woven fabric. It has the characteristics of good high temperature resistance, good low temperature resistance, aging resistance, UV resistance, high elongation, good stability and air permeability, corrosion resistance, sound insulation, mothproof, non-toxic and so on.

Spunbond products

The main products of Spunbond non-woven fabric are polypropylene and polyester non-woven fabrics. Our most common and commonly used applications are non-woven bags, non-woven packaging, etc.; it is easier to identify Spunbond non-woven fabric, generally two-way The fastness is good. Generally, the rolling point of Spunbond non-woven fabric is diamond-shaped.

Melt-blown fabric uses polypropylene as the main raw material, and the fiber diameter is 1 to 5 microns. There are many voids, fluffy structure and good wrinkle resistance. The ultrafine fibers with unique capillary structure can increase the number and surface area of ​​fibers per unit area, so that Melt-blown fabric has good filterability, shielding, heat insulation and oil absorption Sex. It can be used in the fields of air, liquid filter materials, isolation materials, absorption materials, mask materials, thermal insulation materials, oil absorption materials and wipe cloths.

Melt-blown fabric filter material is made of polypropylene microfibers 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 thermal adhesion between the fibers. Therefore, 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.

How

How the Melt-blown fabric is constructed

The following paragraph of this article will introduce the related production process of Melt-blown fabric. The production process of Melt-blown fabric is mainly divided into three steps: melt extrusion, melt-blown process, and electret treatment. Specifically, Melt-blown fabric uses high-speed hot air flow to draw the extruded polymer melt through the spinneret holes of the die nozzle. From this, microfibers are formed and collected on a condensate screen or drum, and at the same time self-bond to become a Melt-blown fabric.

Reasons

Reasons why Melt-blown fabric becomes brittle after production

1. If the aspect ratio of the spinneret of Melt-blown fabric is small, the holes are thick and short. After the polymer is sprayed, the fibers are thicker, the gaps are larger, and the water absorption is stronger for a long time , so the Melt-blown fabric is neither soft nor brittle.

The features of BFE 99 masks

BFE in BFE 99 masks means bacterial filtration effect, which refers to the material's resistance to bacterial penetration. The reported results of BFE 99 masks are shown in percentage data, corresponding to the ability of the material to resist bacterial penetration. The higher the value, the better its filtration performance.
