5. Spunbonded nonwovens:
After the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into nets, which are then self-bonded, heat-bonded, chemically bonded or mechanically strengthened to make the nets non-woven.
6. Melt-blown nonwovens:
its process: polymer feeding – – melt extrusion – – fiber formation – – fiber cooling – – Netting – – reinforcement into cloth.
7. Needle-punched non-woven fabric:
It is a kind of dry non-woven fabric. Needle-punched non-woven fabric uses the puncture function of needle to reinforce the fluffy web into cloth.
8. Sewing nonwovens:
It is a kind of dry nonwovens. Sewing is to use warp-knitted coil structure to reinforce fibre webs, yarn layers, non-textile materials (such as plastic sheets, plastic thin metal foil, etc.) or their combination to make nonwovens.
