Melt-blown non-woven material manufacturing method

Abstract

The invention discloses a melt-blown non-woven material manufacturing method, and aims to provide a melt-blown non-woven material manufacturing method which is good in forming effect, high in structural stability and high in fiber continuity, and the key points of the technical scheme are as follows: by selecting materials, the mixed materials comprise polypropylene, a fluorine-containing polymer and an electret; molding and electret effects of melt-blown non-woven material fibers are controlled, the integral molding effect of the melt-blown cloth is improved, the practicability is high, and in order to improve the molding effect of electret master batch, 50-80 parts of polypropylene resin, the fluorine-containing polymer, the electret, a lubricant and an antioxidant are taken from 200 parts of polypropylene resin and are uniformly blended and extruded to form a mixture, the mixture is repeatedly and uniformly stirred, the uniform distribution effect of the fluorine-containing polymer and the electret is improved, the good molding and electret effect is ensured, the practicality is high, the structure is simple, and the melt-blown non-woven material manufacturing method is suitable for the technical field of medical product manufacturing.

Description

Technical field[0001]The present invention relates to the field of medical supplies manufacturing techniques, and more particularly, it relates to a method for producing a meltblown nonwoven material.Background technique[0002]The traditional meltblown nonwoven material needs to ensure its fiber surface roughness, the crystalline form structure, and the stability of the fibrous web size, and to ensure uniform stability of the army.[0003]The method for producing a traditional meltblown nonwoven material requires the preclo to the material, and then carry out mixing of the material, the selection of the elective masterbatch, and finally mix the elective master particles with the remaining material to form. Melting polypropylene nonwoven material.[0004]At present, the production method of meltblown nonwoven material on the market is poor when the material is mixed, the agitation is poor, resulting in less distribution between each component is not uniform, thereby affecting the meltblow...

AI Technical Summary

Problems solved by technology

[0004] At present, in the manufacturing method of melt-blown nonwoven materials on the market, when the material is mixed, melted and stirred, the stirring effect is poor, resulting in uneven distribution between the components, which affects the melt-blown effect; In the process, because the temperature of the fiber will drop suddenly when it leaves the die, if the temperature drops under the action of traction, the continuity of the fiber will be reduced, which will affect the forming effect of the melt-blown cloth, and it will also be in the melt-blown die. The outlet of the outlet forms a node, which affects the subsequent processing operations
