Spunlacing is the process of spraying high-pressure micro-fine water onto one or more layers of fiber webs to entangle the fibers with each other, so that the web is reinforced and has a certain strength.
Thermally bonded non-woven fabric refers to a fibrous or powdery hot-melt adhesive reinforcing material added to the web, and the web is heated and melted to be cooled and consolidated into a cloth.
Airlaid non-woven fabrics can also be called non-dust paper, dry papermaking non-woven fabrics. 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 agglutinate the fiber on the reticular curtain, and the fiber network is then reinforced into a cloth.
In the wet non-woven fabric, the fiber raw material placed in an aqueous medium is opened into single fibers, and at the same time, different fiber raw materials are mixed to form a fiber suspension slurry, and the suspension slurry is transported to a network forming mechanism, and the fibers are laid in a wet state. Reinforced into cloth.
Spun-bonded non-woven fabrics are laid after the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a web, and the webs are then subjected to self-adhesion, thermal bonding, chemical bonding, or mechanical reinforcement. The web becomes a non-woven fabric.
The process of meltblown nonwoven fabrics: polymer feed - melt extrusion - fiber formation - fiber cooling - web formation - reinforcement into cloth.
A needle-punched non-woven fabric is a kind of dry non-woven fabric. The acupuncture non-woven fabric uses the puncture action of a puncture needle to reinforce the fluffy fiber web into a cloth.
The stitch-bonded non-woven fabric is a type of dry-laid non-woven fabric. The stitch-bonding method utilizes a warp-knitted structure on a web, a yarn layer, a non-woven material (such as a plastic sheet, a plastic thin metal foil, etc.) or a combination thereof. The body is reinforced to make a non-woven fabric.
