Classification of Nonwoven Fabrics

I. Classification by Production Process

1. Spunlace Nonwoven Fabric
   High-pressure micro-water jets are sprayed onto one or more layers of fiber webs, entangling the fibers together to reinforce the web and provide strength. The resulting fabric is spunlace nonwoven.

1. Thermally Bonded Nonwoven Fabric
   Fiber or powder-like thermoplastic bonding materials are added to the fiber web, which is then heated to melt and cooled to form a bonded fabric.
2. Airlaid Pulp Nonwoven Fabric
   Also known as dust-free paper or dry-laid paper nonwoven. It uses airlay technology to separate wood pulp fibers into individual fibers, which are then aggregated onto a forming screen by airflow and reinforced into fabric.
3. Wet-laid Nonwoven Fabric
   Fiber materials dispersed in water are separated into individual fibers and mixed to form a fiber suspension. The suspension is transported to a web-forming mechanism, where fibers are laid into a web in a wet state and then reinforced into fabric.
4. Spunbond Nonwoven Fabric
   After polymer extrusion and stretching to form continuous filaments, the filaments are laid into a web. The web is then bonded through self-adhesion, thermal bonding, chemical bonding, or mechanical reinforcement to form nonwoven fabric.
5. Meltblown Nonwoven Fabric
   The process involves: polymer feeding → melt extrusion → fiber formation → fiber cooling → web formation → reinforcement into fabric.
6. Needle-punched Nonwoven Fabric
   A type of dry-laid nonwoven, needle-punched fabric is reinforced by the piercing action of barbed needles that entangle the loose fiber web.

1. Stitch-bonded Nonwoven Fabric
   Another dry-laid nonwoven, stitch-bonding uses warp-knit loop structures to reinforce fiber webs, yarn layers, non-textile materials (e.g., plastic sheets, metal foils), or their combinations into nonwoven fabric.

II. Classification by Application

1. Medical & Hygiene Nonwoven Fabrics
   Surgical gowns, protective clothing, sterilization wraps, masks, diapers, household wipes, cleaning cloths, wet wipes, magic towels, soft rolls, beauty products, sanitary napkins, panty liners, and disposable hygiene fabrics.
2. Home Decoration Nonwoven Fabrics
   Wall coverings, tablecloths, bed sheets, bedspreads, etc.
3. Apparel Nonwoven Fabrics
   Linings, fusible interlinings, batting, shaped cotton, synthetic leather base fabrics, etc.
4. Industrial Nonwoven Fabrics
   Filter materials, insulation materials, cement bags, geotextiles, wrapping fabrics, etc.
5. Agricultural Nonwoven Fabrics
   Crop covers, seedling cloths, irrigation fabrics, thermal insulation curtains, etc.
6. Other Nonwoven Fabrics
   Space cotton, nonwoven slippers， thermal & sound insulation materials, oil-absorbent felts, cigarette filters, tea bags, etc.
