Production process of hydrophobic melt-blown cloth

Abstract

The invention belongs to the technical field of melt-blown cloth, and particularly relates to a production process of hydrophobic melt-blown cloth. The production process comprises a melt-blown clothdouble-sided embossing machine and melt-blown cloth installed in the melt-blown cloth double-sided embossing machine, wherein the melt-blown cloth double-sided embossing machine comprises an outer shell and an embossing assembly, the embossing assembly comprises a driving roller, a steel wire embossing net, a heating roller, a heat collecting cover and a heating resistance wire, the driving rolleris installed on the inner surface of the outer shell, the steel wire embossing net is arranged outside the driving roller in a sleeving manner, and the two ends of the heating roller are rotationallyinstalled on the inner surface of the outer shell. The embossing assembly is composed of the driving roller, the steel wire embossing net, the heating roller, the heat collecting cover and the heating resistance wire, and the embossing assembly is installed inside the outer shell, so that the embossing assembly can conveniently emboss the melt-blown cloth, meanwhile, the steel wire embossing netis wrapped outside the driving roller, the heating roller is in contact with the inner surface of the steel wire embossing net, and meanwhile, the heat collecting cover covers the outside of the heating roller.

Description

technical field [0001] The invention belongs to the technical field of meltblown cloth, and in particular relates to a production process of hydrophobic meltblown cloth. Background technique [0002] Melt-blown cloth is a kind of cloth made of polypropylene as the main raw material, and its fiber diameter can reach 1-5 microns. These ultra-fine fibers with unique capillary structure can increase the number and surface area of ​​fibers per unit area, so that the melt Spray cloth has good filterability, shielding, heat insulation and oil absorption, and can be used in air, liquid filter materials, isolation materials, absorption materials, mask materials, thermal insulation materials and wiping cloths and other fields. Melt-blown cloth is an excellent material for masks. In large, medium and small medical institutions, in areas affected by earthquakes and floods, and in seasons of high incidence of SARS, bird flu and H1N1 viruses, melt-blown cloth plays an indispensable role w...
