Classification of polypropylene non-woven fabrics

by:Sunshine     2021-04-04
1. Polypropylene granular spunlace non-woven fabric


   Polypropylene granular spunlace non-woven fabric 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 webs can be reinforced and have a certain strength.


   2. Acrylic granular heat-sealing non-woven fabric


   Acrylic pellet 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 reinforce it into a cloth.


  3. Propylene particle pulp air laid non-woven fabric


   Airlaid propylene particle material non-woven fabric can also be called dust-free paper, dry paper-making non-woven fabric. 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.


   Fourth, acrylic granular wet-laid non-woven fabric


  Acrylic granular wet-laid non-woven fabric is to open the fiber raw materials placed in the water medium into single fibers, and at the same time mix different fiber raw materials to form a fiber suspension slurry, which is transported to the web forming mechanism, and the fibers are in In the wet state, a net is formed and then reinforced into a cloth.


   5. Acrylic granular spunbond non-woven fabric


   Propylene particle 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 bonded by itself, thermally bonded, and chemically bonded. Or mechanical reinforcement method to make the fiber web become a spunbonded non-woven fabric of acrylic particles.


  VI. Polypropylene granule meltblown non-woven fabric


   Polypropylene pellet melt-blown non-woven fabric process: polymer feeding---melt extrusion---fiber formation---fiber cooling---web formation---reinforcement into cloth.


  七、Polypropylene granule needle punched non-woven fabric


   Polypropylene particle needle-punched non-woven fabric is a kind of dry-laid non-woven fabric. Polypropylene particle needle-punched non-woven fabric uses the puncture effect of needles to reinforce the fluffy web into a cloth.


  八、Polypropylene granule stitched non-woven fabric


   Polypropylene pellet stitch-bonded non-woven fabric is a kind of dry-laid non-woven fabric. The stitch-bonding method uses a warp-knitted loop structure to align fiber webs, yarn layers, non-woven materials (such as plastic sheets, plastic thin metal Foil, etc.) or their combination to be reinforced to make a non-woven fabric
