Introducing The Classification Of Non-woven Fabrics By Production Process
Non-woven Shopping Bag has many styles, beautiful, environmentally friendly and practical. The non-woven fabrics selected are all spunbond non-woven fabrics. Today, the editor will talk about the categories of non-woven fabrics classified according to the production process.
Spunlace non-woven fabric
The spunlace process is to spray high-pressure fine water flow onto one or more layers of fiber webs to entangle the fibers with each other, so that the fiber web can be reinforced and have a certain strength.
Heat-bonded non-woven fabric
Thermal bonding non-woven fabric refers to adding fibrous or powdery hot-melt bonding reinforcement materials to the fiber web, and the fiber web is then heated, melted and cooled to reinforce it into cloth.
Air-laid non-woven fabric
Air-laid non-woven fabric can also be called dust-free paper and dry papermaking non-woven fabric. It uses air-laid technology to open the wood pulp fiberboard into a single fiber state, and then uses air-laid method to make the fibers condense on the mesh curtain, and the fiber web is reinforced into cloth.
Wet-laid nonwovens
Wet-laid nonwovens are made by opening fiber raw materials placed in a water medium into single fibers, and mixing different fiber raw materials to form a fiber suspension slurry. The suspension slurry is transported to a web-forming mechanism, and the fibers are formed into a web in a wet state and then reinforced into a cloth.
Spunbond nonwovens
Spunbond nonwovens are made by laying the filaments into a web after the polymer has been extruded and stretched to form continuous filaments. The web is then bonded, thermally bonded, chemically bonded or mechanically reinforced to make the web into a nonwoven fabric.
Meltblown nonwovens
The process of meltblown nonwovens: polymer feeding---melt extrusion---fiber formation---fiber cooling---web formation---reinforcement into cloth.
Needle-punched nonwovens
Needle-punched nonwovens are a type of dry-laid nonwovens. Needle-punched nonwovens use the puncture of needles to reinforce the fluffy web into cloth.
Stitchbonded nonwoven fabric
Stitchbonded nonwoven fabric is a type of dry nonwoven fabric. The stitchbonding method uses a warp knitting coil structure to reinforce the fiber web, yarn layer, non-woven material (such as plastic sheet, plastic thin metal foil, etc.) or their combination to make a nonwoven fabric.
