What is melt blown cloth?
The epidemic has made masks a necessity in people's lives, and melt blown cloth is one of the important materials for making masks. So, what exactly is melt blown cloth?

Melt blown cloth is the core material of masks, mainly made of polypropylene as the main raw material, and the fiber diameter can reach 1 to 5 microns. There are many voids, fluffy structure, and good anti-wrinkle ability. The ultra-fine fibers with unique capillary structure increase the number and surface area of fibers per unit area, so that the melt blown cloth has good filtration, shielding, heat insulation and oil absorption. 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.

The melt blown cloth filter material is randomly distributed and bonded together by polypropylene microfibers, and the appearance is white, smooth and soft. The random distribution of the fibers provides more opportunities for thermal bonding, thus making the meltblown gas filter material have a larger specific surface area and a higher porosity.

The history of meltblown cloth

The melt blown process is one of the non-woven processes, which originated in the early 1950s. At that time, the U.S. Naval Laboratory began to develop filter materials with ultra-fine filtering effects in order to collect radioactive particles produced by nuclear tests.

In the mid-1960s, Exxon and Accurate Co., Ltd. jointly produced the first prototype of meltblown equipment and applied for a patent. At present, in addition to Exxon's proprietary meltblown technology, some other companies (such as 3M in the United States, Freudenberg in Germany, etc.) have also successfully developed their own meltblown nonwoven technology.

Process principle of meltblown

The melt-blown non-woven process is to use high-speed hot air to draw a thin stream of polymer melt extruded from the die orifice, thereby forming ultra-fine fibers and condensing on the net curtain or drum, and relying on their own adhesion Together it becomes a non-woven fabric.

Application range of melt blown cloth

1. Medical and sanitary cloths: surgical gowns, protective clothing, disinfection wraps, masks, diapers, sanitary napkins, etc.

2. Home decoration cloth: wall cloth, table cloth, bed sheet, bedspread, etc.

3. Garment cloth: lining, adhesive interlining, wadding, shaped cotton, various synthetic leather base cloth, etc.

4. Industrial cloth: filter material, insulating material, cement packaging bag, geotextile, covering cloth, etc.

5. Agricultural cloth: crop protection cloth, seedling raising cloth, irrigation cloth, thermal insulation curtain, etc.

6. Others: space cotton, thermal insulation materials, linoleum, cigarette filters, tea bags, etc.
