Melt-blown fabric production and manufacturing method

Abstract

The invention provides a melt-blown fabric production and manufacturing method which is implemented through matching of a storage frame, a conveying pump, a conveying pipe, a filtering device, a spinneret die head and a support frame, and can solve the problems that a large number of impurities are intercepted due to the filtering effect of a multi-layer fine-mesh metal screen, the intercepted impurities are more and more along with the accumulation of time, and blockage is caused by excessive accumulation of the impurities for a long time, so that in order to prevent blockage caused by excessive accumulation of the impurities for a long time, people usually close equipment and take out the multi-layer fine-mesh metal screen for regular cleaning, but due to the fact that the temperature ofpolymer melt is high, scalding of the people are easily caused when the multi-layer fine-mesh metal screen in the polymer melt are taken out, and direct economic loss is often caused by stopping of the equipment and the like.

Description

technical field [0001] The invention relates to the technical field of production of melt-blown cloth, in particular to a production method of melt-blown cloth. Background technique [0002] Melt blown cloth mainly uses polypropylene as the main raw material, and the fiber diameter can reach 1~5 microns. There are many voids, fluffy structure, and good wrinkle resistance. The ultrafine fibers with unique capillary structure increase the number and surface area of ​​fibers per unit area, so that the melt blown cloth has good filterability, shielding, heat insulation and oil absorption. It can be used in air and liquid filter materials, isolation materials, absorption materials, mask materials, thermal insulation materials, oil absorption materials and wiping cloths and other fields. [0003] In the manufacturing process of meltblown cloth, the polymer melt should be filtered before entering the spinneret die to filter out impurities and prevent clogging of the spinneret die....

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a production method of melt-blown cloth, which can solve the problem of intercepting a large amount of impurities due to the filtering effect of multi-layer fine-mesh metal screens. As time accumulates, the intercepted impurities become more and more More and more, it will still cause blockage in the long run. In order to prevent blockage caused by excessive accumulation of impurities, personnel usually shut down the equipment, take out the multi-layer fine-mesh metal screen and clean it regularly. However, due to the high temperature of the polymer melt, When the multi-layer fine-mesh metal screen in the polymer melt is taken out, it is easy to cause people to be scalded, and the stop of the equipment will often cause direct economic losses and other problems.
