　　In ancient times, the textile fibers used by people were all natural, such as silk, wool, and cotton. Among them, mulberry silk is one of the better fibers, but it is still insufficient in terms of wearing comfort or beautiful appearance. With the passage of time, people are dissatisfied with traditional textile technology, which makes people pay more attention to the development of the textile industry. They are committed to discovering the characteristics of various chemical fibers, providing new knowledge, and developing a high-performance fiber material-ultrafine fiber, which is unmatched by natural fiber size.

　　As a melt-blown cloth manufacturer in the industry, we have successfully developed melt-blown microfiber scrubbing cloths, which can be used for heavy oil scrubbing, machine tool and large-scale equipment maintenance, various ink leakage removal, automobile pre-painting treatment and exterior cleaning of car bodies. In addition, the melt-blown microfiber cloth is made of melt-blown microfiber, which has the characteristics of no scratches in the appearance of the product, and good insulation and chemical resistance. Our technology keeps improving, and our products are getting better and better. After many times of practice, it has been proved that the meltblown microfiber scrubbing cloth has the advantages of soft hand feeling, fast absorption speed, no debris falling on the surface, and high absorption ratio. At the same time, the praise from customers also shows that our products are superior to similar products in scrubbing performance.

　　Production process of melt blown cloth manufacturers

　　1. Melt extrusion

　　The extrusion volume of the polymer melt produced by the meltblown fabric factory affects the linear density and output of the fiber. The higher the number of grams of polymer melt extruded from the fuse hole per minute, the thicker the fiber. Therefore, under the premise of ensuring fiber fineness, it is necessary to increase the number of spinneret holes to increase the output of meltblown nonwovens.

　　2. Draught heat flow velocity

　　The main process parameter of the secondary hot melt flow rate during the injection process directly affects the fineness of the fiber. The polymer melt used for extrusion and a certain amount of melt viscosity, higher air drawing speed, linear drawing effect, microfluid for melt spinning of polymer? In industrial production, with the rapid development of information technology, ventilated hot air can be used to compensate for the continuous change of fiber hole diameter caused by the increase in polymer extrusion time, that is, the flow of secondary hot air must match the polymer extrusion .

　　3. Melting temperature

　　The melt blown temperature of the melt blown cloth is the working temperature, which can be used to adjust the melt viscosity of the polymer melt nozzle. The melting temperature is usually higher than the melting point of the PP resin in a viscous flow state. When other process conditions remain constant, the melt viscosity of the polymer decreases and the melt fluidity becomes better. Therefore, microfibers can be easily obtained by melt spraying by using a high MF polymer chip material. However, if the melt viscosity of the meltblown fabric factory is too small, it will cause the melt flow to expand too much, and the short ultrafine fibers will fly into the air and cannot be collected. This is called the "flying" phenomenon in the meltblown process. .
