What are the main classification of nonwoven fabric?
Nonwoven fabric, also called nonwoven cloth, which is composed of oriented or random fibers.
The main classification of nonwoven fabrics are as follows:
1. Spunlace Nonwoven Fabric
The spunlace process is to spray a high pressure micro-water stream onto one or more layers of fiber webs, to make the fibers are entangled with each other, can be strengthened.
2. Heat Sealed Nonwoven Fabric
Thermally bonded nonwoven fabric refers to adding fibrous or powdery hot-melt bonding and reinforcing materials to the fiber web, and then heated, melted and cooled to be consolidated into a cloth.
3. Pulp Airlaid Nonwoven Fabric
It uses the airlaid technology to open the wood pulp fiber board into a single fiber state, and then uses the airflow method to condense the fibers on the screen forming curtain, consolidated into a cloth.
4. Wet Nonwoven Fabric
The wet nonwoven fabric is to open the fiber raw materials placed 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 einforced into cloth.
5. Spunbond Nonwoven Fabric
After the polymer is formed into continuous filaments, the filaments are laid into a web, and the web is then subjected to self-bonding, thermal bonding, chemical bonding, or mechanical reinforcement methods to make the web into a nonwoven fabric.
6. Meltblown Nonwoven Fabric
The process of meltblown nonwoven fabric: polymer feeding melt extrusion fiber formation fiber cooling netting reinforcement into cloth.
7. Needle Punched Nonwoven Fabric
Needle punched nonwoven fabric uses the puncture effect of the needle to strengthen the fluffy web into a cloth.
