1. Spunlace non-woven fabric
The spunlace process is to spray a high-pressure micro-water stream onto one or more layers of fiber webs, so that the fibers are entangled with each other, so that the fiber webs can be strengthened and have a certain strength.
Second, heat-sealed non-woven fabric
Thermally bonded non-woven fabric refers to adding fibrous or powdery hot-melt bonding and reinforcing materials to the fiber web, and the fiber web is then heated, melted and cooled to be consolidated into a 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. It uses the 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 the fiber web is consolidated into a cloth.
4. 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 transported to the web forming mechanism, and the fibers are netted under wet conditions. Reinforced into cloth.
V. Spunbond non-woven fabric
Spunbond nonwoven 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. Meltblown nonwoven
The process of melt-blown non-woven fabric: polymer feeding --- melt extrusion --- fiber formation --- fiber cooling --- netting --- reinforcement into cloth.
7. Needle-punched non-woven fabric
Needle-punched non-woven fabric is a kind of dry non-woven fabric. Needle-punched non-woven fabric uses the puncture effect of the needle to strengthen the fluffy web into a cloth.
8. Stitched non-woven fabric
Stitch-bonded non-woven fabric is a kind of dry-laid non-woven fabric. The stitch-bonded method is to use warp-knitted coil structure to web, yarn layer, non-woven materials (such as plastic sheet, plastic thin metal foil, etc.) or their combination The body is reinforced to make a non-woven fabric.
