The wet non-woven fabric is to open the fiber raw

Second, heat-sealing non-woven fabric Thermally bonded non-woven fabric refers to adding fibrous or powdery hot-melt adhesive reinforcement materials to the fiber web, and the fiber web is then heated, melted, cooled and consolidated into a cloth. Needle-punched non-woven fabric Needle-punched non-woven fabric is a kind of dry method non-woven fabric. KN90 Respirator Company 7. 5. It uses air-laid technology to open the wood pulp fiber board into a single fiber state, and then uses the air-flow method to condense the fibers on the screen-forming curtain, and then strengthen the fiber into a cloth.

The stitch-bonded method is to use warp-knitted coil structure to web, yarn layer, non-woven material (such as plastic sheet, plastic thin metal foil, etc. Needle-punched non-woven fabric uses the puncture effect of the needle to strengthen the fluffy web into a cloth. Meltblown nonwoven fabric The process of melt-blown non-woven fabrics: polymer feeding --- melt extrusion --- fiber formation --- fiber cooling --- netting --- reinforcement into cloth.. Wet non-woven fabric

The wet non-woven fabric is to open the fiber raw materials in the aqueous medium into single fibers, and at the same time mix the different fiber raw materials to make a fiber suspension slurry, and the suspension slurry is sent to the web forming mechanism, and the fibers are netted under wet conditions Reinforced into cloth. Three, pulp airlaid non-woven fabric The air-laid non-woven fabric can also be called dust-free paper and dry paper-making non-woven fabric.) or their combination The body is reinforced to make a non-woven fabric. 8. Spunbond non-woven fabric Spunbond non-woven fabric is after the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a net, and the fiber web is then subjected to self-bonding, thermal bonding, chemical bonding or mechanical reinforcement methods to make

The web becomes nonwoven. 6. Stitched non-woven fabric Stitch-bonded non-woven fabric is a kind of dry-laid non-woven fabric. Spunlace non-woven fabric The spunlace process is to spray high-pressure micro-water flow onto one or more layers of fiber meshes to make the fibers entangle with each other, so that the fiber meshes can be strengthened and have a certain strength.1
