What Is Meltblown Cloth?

According to the composition of non-woven fabrics, there are polyester, polypropylene, nylon, spandex, acrylic, etc.; different components will have completely different styles of non-woven fabrics. There are many production processes in the manufacture of non-woven fabrics. Melt-blown non-woven fabric is a process of the melt-blown method, which is one of the non-woven fabric production processes, and it is also a method of direct polymer formation. The polymer melt-extruded by the screw extruder is extremely stretched by high-speed and high-temperature air jet blowing or other means to form extremely fine fibers and then gathered on the web forming drum or web curtain A fiber web is formed, and finally strengthened by self-adhesive action to make a meltblown fiber nonwoven fabric.

Melt blown cloth is mainly made of polypropylene, and the fiber diameter can reach 1 to 5 microns. There are many voids, fluffy structures, and good anti-wrinkle ability. These ultrafine fibers with unique capillary structure increase the number and surface area of fibers per unit area so that the meltblown cloth has good filtration, shielding, heat insulation, and oil absorption. . It can be used in air, liquid filter materials, isolation materials, absorbing materials, mask materials, thermal insulation materials, oil-absorbing materials and wiping cloths.

The fiber diameter of the melt-blown layer is extremely thin, basically about 2 microns (um), so it is only one-tenth of the diameter of the spun bond layer. The thinner the meltblown layer, the more it can block the entry of tiny particles. For example, KN95 mask refers to Under normal circumstances, the flow of 85L can block 95% of the tiny particles (0.3um), which plays a vital role in filtering bacteria and preventing blood penetration, which is why it is called the heart of a mask.

The field of application of meltblown cloth is very wide, but it is mainly used in the medical industry, such as surgical gowns, protective clothing, disinfection cloths, masks, diapers, and sanitary napkins. At the same time, it can also be used to make household items, such as wall coverings, tablecloths, bedspreads, bedspreads, etc.; it can also be used to make linings, adhesive linings, flocs, etc., clothing with stereotypes, and various synthetic leather bases. In addition, meltblown cloth has many industrial and agricultural uses.
