The Difference between Different Non-woven Fabrics
Spunlaced non-woven fabrics: It sprays high-pressure micro-water into one or more layers of fiber mesh, so that the fibers are intertwined, so that the fiber mesh can be strengthened and has a certain strength.
Thermo-bonded nonwoven fabrics: refers to the addition of fibrous or powdery hot-melt bonding reinforcement materials into the fibre mesh, which is then strengthened by heating, melting and cooling.
Pulp air-blown non-woven fabrics: also known as dust-free paper, dry-process paper-making non-woven fabrics. It uses air-flow netting technology to loosen the wood pulp fiberboard into a single fiber state, and then uses air-flow method to agglutinate the fibers on the screen curtain, and then reinforce the fibernet into cloth.
Wet non-woven fabrics: It is to loosen the fibre raw materials in the water medium into single fibers, at the same time mix different fibre raw materials to make fibre suspension slurry, which is conveyed to the netting mechanism, and the fibers are netted and consolidated into cloth in the wet state.
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.
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.
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.
