What are the classifications of polyester non-woven fabrics?

Polyester non-woven fabric is a kind of fabric that does not need to be spun and weaves. It just aligns or randomly arranges textile short fibers or filaments to form a fiber network structure, which is reinforced by mechanical, thermal bonding or chemical methods. . What are the classifications of polyester non-woven fabrics?

Classification of polyester non-woven fabrics:

First, spunlace non-woven fabric
The spunlace process is to spray a high-pressure fine water stream onto one or more layers of fiber webs to entangle the fibers with each other, so that the fiber webs can be reinforced and have a certain strength.

Second, heat-sealing non-woven fabric
Thermal bonding non-woven fabric refers to adding fibrous or powdery hot-melt bonding reinforcement material to the fiber web, and then the fiber web is heated, melted and cooled to be consolidated into a cloth.

3. Pulp air laid non-woven fabric
Air-laid non-woven fabrics can also be called dust-free paper and dry-laid non-woven fabrics. It uses air-laid technology to open the wood pulp fiberboard into a single fiber state, and then uses air-flow method to agglomerate the fibers on the web curtain, and then reinforce the fiber web into a cloth.

Four, wet-laid non-woven fabric
Wet-laid non-woven fabrics are used to open fiber raw materials placed in an aqueous medium into single fibers, and at the same time mix different fiber raw materials to form a fiber suspension slurry, which is transported to a web forming mechanism, and the fibers are in a wet state. Form a net and then reinforce into a cloth.

Five, spunbond non-woven fabric
Spunbond non-woven fabric is formed after the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a web, and the web is self-bonded, thermally bonded, chemically bonded or mechanically reinforced Method to make the web into a non-woven fabric.

VI. Meltblown non-woven fabric
The process of melt-blown non-woven fabrics: polymer feeding---melt extrusion---fiber formation---fiber cooling---netting---reinforcement into cloth.

Seven, needle punched non-woven fabric
Needle-punched non-woven fabric is a kind of dry-laid non-woven fabric. Needle-punched non-woven fabric uses the piercing effect of needles to reinforce the fluffy web into a cloth.

Polyester non-woven fabrics are not interwoven and braided one by one, but the fibers are directly bonded together by physical methods. The classification of polyester non-woven fabrics is mainly the above, and we all choose the above classifications that we need.
