Problems solved by technology

[0004] The object of the present invention is to solve the shortcomings in the prior art, such as: the existing method does not fully process the raw materials in the preparation process, resulting in raw materials containing There are more impurities, and the impurities melted in the fabric will easily affect the quality of the fabric. At the same time, the fabric is generally cooled naturally during the production of blown silk. Natural cooling leads to the same length and thickness of the blown silk, which cannot meet the production requirements. Requirements for different types of fabrics

Abstract

The invention discloses melt-blown cloth with a double-layer structure and a preparation method of the melt-blown cloth, and relates to the technical field of melt-blown cloth. The melt-blown cloth comprises two pieces of single-layer cloth and a bonding layer, wherein the two pieces of single-layer cloth are bonded through the bonding layer. Through two filtering processes, a melt can be deeply filtered, the filtering effect on the melt is improved, and the influence on the quality of the cloth due to the fact that a large number of impurities remain is avoided; and the raw materials are stirred through stirring equipment, so that the raw materials can be fully scattered, and the impurities in the raw materials can be better filtered out. Natural cooling is not performed, the cooling timeis prolonged, correspondingly, the stretching distance of the silk yarn can be effectively shortened, and besides, the thickness of the silk yarn can be effectively controlled, so that cloth of different specifications can be manufactured during cloth manufacturing. A pressure roller is arranged to extrude the two pieces of the cloth for adhesion, the double-layer structure of the cloth is achieved, and the effect of the cloth is improved.

Description

technical field [0001] The invention relates to the technical field of melt-blown cloth, in particular to a double-layer melt-blown cloth and a preparation method thereof. Background technique [0002] With the development of science and technology, melt-blown cloth was invented and gradually widely used. Melt-blown cloth is a filter material with polypropylene as the main raw material. The fiber diameter can reach 1-5 microns. These ultra-fine fibers with unique capillary structure increase the number and surface area of ​​fibers per unit area, so that the melt-blown cloth has good filtration, shielding, heat insulation and oil absorption. It can be used in air, liquid filter materials, isolation materials, absorption materials, mask materials, thermal insulation materials and wiping cloths, etc., and melt blown cloth has a wide range of applications in many fields, such as medical and health, surgical gowns, protective clothing, Disinfection cloth, masks, diapers and wome...
