Composite type melt-blown fabric web-forming method

Abstract

In the industrial enterprise production process, various pollutions exist, so that an affordable gauze mask with good air tightness and good air permeability is in in urgent need in the current market. A core of the gauze mark is a melt-blowing fabric which is low in tensile strength; the melt-blowing fabric and a spunbond nonwoven fabric form the gauze mask after melt-blowing; and a gap exists between the melt-blowing fabric and the spunbond fabric after the melt-blowing fabric and the spunbond fabric are simply superimposed, so that a large number of bacteria can survive. The technical scheme of the invention is formed by a melt-blowing mould, melt-blowing filaments, a web-forming machine fabric, a suction fan, the spunbond nonwoven fabric, an unreeling machine, a shaft, a guide roller,a flattening roller and a refrigeration fan. The invention has the beneficial effects that sprayed filaments sprayed out by the melt-blowing mould are hot propylene (PP) which is directly bonded ontothe spunbond nonwoven fabric, so that the firmness in bonding is realized, and the tensile strength is greatly improved.

Description

technical field [0001] The invention is a composite melt-blown cloth forming method, and specifically relates to medical institutions, civilian use, and industrial protection. Background technique [0002] There are various pollutions in the production process of industrial enterprises. Now the market urgently needs a mask with good air tightness and good air permeability that everyone can afford. The core of the mask is melt-blown cloth, which has low tensile strength; melt-blown Make a mask with spun-bonded non-woven fabric. There is a gap between the melt-blown and spun-bonded fabrics, which is enough for a large number of bacteria to survive. Contents of the invention [0003] The purpose of the present invention is to provide a method for forming a composite melt-blown cloth. [0004] The technical solution of the present invention is composed of a melt-blown mold, a melt-blown yarn, a web-forming machine cloth, a suction fan, a spun-bonded non-woven fabric, an unwin...
