Background and characteristics of spunbond

Background and characteristics of spunbond

(Summary description)Polypropylene spunbond non-woven fabric is a kind of non-woven fabric, which is made of polypropylene as raw material, polymerized into a network by high-temperature drawing, and then bonded into a fabric by hot rolling. Because the technological process is simple, the output is large, and it is non-toxic and harmless to the human body. Therefore, it is widely used in sanitary materials and other fields.

Information

Polypropylene spunbond non-woven fabric is a kind of non-woven fabric, which is made of polypropylene as raw material, polymerized into a network by high-temperature drawing, and then bonded into a fabric by hot rolling. Because the technological process is simple, the output is large, and it is non-toxic and harmless to the human body. Therefore, it is widely used in sanitary materials and other fields.

customized spunbond

In the non-woven manufacturing method, the spunbond method has obvious advantages in manufacturing technology, product performance and production efficiency. The spunbond method has achieved rapid development that has attracted worldwide attention in the past 20 years. About 40%~50% of non-woven fabrics are produced by the melt spinning method (including spunbond method, meltblown method and composite method of the two).

The important reason for the rapid development of the spunbond method is that it uses synthetic polymers as raw materials, and the method utilizes the principle of chemical fiber spinning. In the process of polymer spinning, continuous filaments are directly bonded after spinning to form a spunbond non-woven fabric.

In addition, spunbond nonwoven products have excellent mechanical properties, and their tensile strength, elongation at break, tear strength and other indicators are better than dry, wet, and meltblown nonwovens. Especially in recent years, the rapid development of spunbond method in production line scale, technology and equipment and product market development has greatly expanded the application field of spunbond non-woven fabrics.

Through the above introduction and analysis of Spunbond, hope it helps you.

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.
