Double-component melt-blown spinneret plate for producing skin-core structure spinning

Abstract

The invention provides a double-component melt-blown spinneret plate for producing skin-core structure spinning. The double-component melt-blown spinneret plate comprises an upper feeding plate, a plurality of groups of feeding ports are uniformly formed in the surface of the upper feeding plate, the plurality of feeding ports comprise a component A port and a component B port, a lower feeding plate is arranged below the upper feeding plate, a plurality of component A flow guide holes are formed in the positions, located at the component A port, of the lower feeding plate, a plurality of component B flow guide holes are formed in the positions, located at the component A port, of the lower feeding plate, an upper distribution plate and a lower distribution plate are sequentially installedbelow the lower feeding plate, the multiple groups of component A flow guide holes and component B flow guide holes penetrate through the upper distribution plate and the lower distribution plate in crossed and reversing modes, an upper spinneret plate is installed below the lower distribution plate, a plurality of afflux holes are formed in the upper spinneret plate in a penetrating mode, a lowerspinneret plate is installed below the upper spinneret plate, a plurality of extrusion holes are formed in the surface of the lower spinneret plate in a penetrating mode, and the lower spinneret plate extrudes the skin-core structure spinning through the extrusion holes. According to the double-component melt-blown spinneret plate, a spinneret plate assembly structure is improved to produce skin-core structure spinning, so that spinning is more durable, and the application range is wider.

Description

technical field [0001] The invention belongs to the technical field of textile equipment, especially for melt-blown spinning equipment, and in particular relates to a two-component melt-blown spinneret for producing skin-core structure spinning. Background technique [0002] The spinneret is also called the spinning cap. The function of the spinneret is to transform the viscous polymer melt or solution into a fine flow with a specific cross-section through the micropores, and solidify through a coagulation medium such as air or a coagulation bath to form filaments. [0003] The main raw material of meltblown cloth is polypropylene (PP), which is an ultra-fine electrostatic fiber cloth with a fiber diameter of about 2 microns. It is also called medical mask melt-blown cloth, melt-blown non-woven fabric, and mask cloth on the Internet. Melt-blown fabric is a kind of non-woven fabric. There are many processing techniques for non-woven fabrics, and the melt-blown method is the...

Problems solved by technology

[0005] However, the spinnerets of the prior art are not satisfied with the production of skin-core structure spinning, therefore, a melt-blown component capable of producing skin-core structure spinning is needed
