spunlace non-woven

The spunlace process is to spray a high-pressure fine water stream onto one or more layers of the fiber web so that the fibers are entangled with each other, so that the fiber web can be reinforced and has a certain strength.


heat sealing non-woven

The thermally bonded non-woven fabric refers to a fibrous or powdery hot-melt adhesive reinforcing material added to the web, and the web is further fused and cooled to form a cloth.


airlaid

Airlaid nonwoven fabric can also be called dust-free paper, dry papermaking non-woven fabric. It uses the air-laid technology to open the wood pulp fiber board into a single fiber state, and then uses a gas flow method to agglomerate the fibers on the mesh curtain, and the fiber web is further reinforced into a cloth.


wet non-woven

The wet-laid non-woven fabric is to open the fiber raw material placed in the water medium into a single fiber, and at the same time mix different fiber raw materials to form a fiber suspension slurry, and the suspended pulp is transported to a web forming mechanism, and the fiber is netted in a wet state. Reinforce into a cloth.

spunbond nonwoven

The spunbonded nonwoven fabric is formed by laminating the filaments after the polymer has been extruded and stretched to form continuous filaments, and the web is subjected to self-bonding, thermal bonding, chemical bonding or mechanical reinforcement. The web becomes a non-woven fabric.


meltblown nonwoven

The process of melt-blown non-woven fabric: polymer feeding---melt extrusion---fiber formation---fiber cooling---forming into the net---reinforcing into cloth.


needle punching non-woven

One type of needle-punched non-woven fabric is a needle-punched nonwoven fabric which is punctured by a lancet to reinforce the fluffy web into a cloth.


stitching non-woven

The stitchbonded nonwoven fabric is a kind of dry non-woven fabric, and the stitching method is a warp knitting fabric structure, a web, a yarn layer, a non-woven material (for example, a plastic sheet, a plastic thin metal foil, etc.) or a combination thereof. The body is reinforced to form a nonwoven fabric.
