Its main uses can be roughly divided into:
(1) Medical and health care cloth: surgical gown, protective garment, disinfection cloth, mask, diaper, female sanitary towel, etc.
(2) Home improvement cloth: wall covering, tablecloth, bed sheet, bedspread, etc. ;
(3) Subsequent fabrics: lining, adhesive lining, filler, special-shaped cotton, various synthetic leather base fabrics, etc.
(4) Industrial cloth: filter material, insulating material, cement packing bag, geotextile, covering cloth, etc.
(5) Agricultural cloth: crop protection cloth, seedling cloth, irrigation cloth, thermal insulation curtain, etc.
(6) Others: space cotton, heat and sound insulation materials, oil-absorbing felt, cigarette filter tips, tea bags, etc.
Classification of non-woven fabrics:
I. Spunlaced nonwovens
The spunlace process is to spray high-pressure micro-water on one or more layers of fiber web, so that the fibers are intertwined and the fiber web is strengthened with certain strength.
Second, heat-seal non-woven fabrics.
Thermal bonding non-woven fabric refers to adding fibrous or powdery hot-melt bonding reinforcing materials to the fiber web, and then heating, melting and cooling the fiber web to strengthen it into cloth.
Third, pulp airlaid nonwovens
Air-laid nonwovens can also be called dust-free paper and dry papermaking nonwovens. It uses the air-laid technology to open the wood pulp fiberboard into a single fiber state, and then uses the air-laid method to bond the fibers to the net curtain, and the fiber net is reinforced into cloth.
Fourthly, wet nonwoven fabric.
Wet-process non-woven fabrics are made by opening fiber raw materials placed in water medium into single fibers, and mixing different fiber raw materials to make fiber suspension slurry, which is conveyed to the web-forming mechanism, and the fibers are web-formed in wet state, and then reinforced into cloth.
5. Spunbonded nonwovens
Spunbonded nonwovens are made by laying the filaments into a net after the polymer is extruded and stretched to form continuous filaments, and then the net is transformed into nonwovens by self-bonding, thermal bonding, chemical bonding or mechanical reinforcement.
Six, melt-blown nonwovens
The technological process of melt-blown nonwovens: polymer feeding-melt extrusion-fiber forming-fiber cooling-web forming-reinforced cloth forming.
Vii. Needle punched nonwovens
Needle punched nonwovens is a kind of dry nonwovens. Needle-punched nonwovens are used to strengthen fluffy fiber webs into cloth by the puncture effect of needles.
Eight, stitching non-woven fabrics
Stitched nonwoven fabric is a dry nonwoven fabric. Sewing method is to use warp-knitted loop structure to strengthen net, yarn layer and nonwoven materials (such as plastic sheet, plastic thin metal foil, etc.). ) or a combination thereof.
