Meltblown nonwovens use high-speed hot air to draw a thin stream of polymer melt extruded from the spinneret of the die, thereby forming ultra-fine fibers and condensing on the curtain net or roller, and relying on self-adhesion. Become a nonwoven.
Meltblown non-woven fabric is a kind of fast-growing non-woven fabric production. It is known abroad as the shortest-flow polymer one-step production process. Its products have many obvious advantages such as high filtration efficiency, low resistance, softness, and network self-knotting and bonding. Currently, meltblown nonwovens are the hottest selling products during the epidemic. In addition, it can also be used as medical and sanitary products, industrial precision wipes, warm materials, oil-absorbing materials, battery separators, imitation leather base cloths, and so on. In many ways its performance is better than similar products of traditional textiles. With the continuous development of post-processing technology, the application areas of meltblown non-woven fabrics will be more extensive.
Production line process flow: polymer preparation → melt extrusion → metering pump → meltblown die head assembly → melt jet stretching → cooling → web receiving → winding
