Nonwoven fabrics (also known as non-woven textiles) are a relatively young and promising emerging field in the textile industry. The nonwoven fabric industry in China began relatively late, but its development has been rapid. In its early stages, nonwoven fabrics were mainly used in the clothing industry as accessories. With the rapid development of society, economy, and science and technology, new products and technologies in nonwoven fabrics are emerging in an endless stream, changing daily, and their applications are becoming increasingly widespread.
The accurate name for nonwoven fabrics should be nonwoven textiles, or simply non-woven fabrics. In standard GB/T5709—1997, "Textiles—Nonwoven Fabrics—Terminology," defines nonwoven fabrics as: sheets, webs, or mats made of oriented or randomly arranged fibers bonded together by friction, cohesion, or adhesion, or a combination of these methods, excluding paper, woven fabrics, knitted fabrics, tufted fabrics, and felted products made by wet fulling. Because it is a fabric that does not require spinning and weaving, but is formed by arranging short or long textile fibers directionally or randomly to form a web structure, and then reinforcing it by mechanical, thermal bonding or chemical methods.
Classification of Nonwoven Fabrics
1. Spunlace Nonwoven Fabric:
The spunlace process involves spraying high-pressure micro-jet water onto one or more layers of fiber web, causing the fibers to entangle together, thereby strengthening the web and giving it a certain strength.
2. Thermally bonded nonwoven fabric:
Thermoly bonded nonwoven fabric refers to a fabric in which fibrous or powdered hot-melt adhesive reinforcing materials are added to the fiber web, and the fiber web is then heated, melted, and cooled to form a fabric.
3. Air-laid nonwoven fabric: Air-laid nonwoven fabric, also known as dust-free paper or dry-process papermaking nonwoven fabric, is made by opening wood pulp fiberboard into single fibers using air-laid technology, then using airflow to condense the fibers onto a web-forming screen, and finally reinforcing the web into a fabric.
4. Spunbond Nonwoven Fabric: Spunbond nonwoven fabric is produced by extruding and stretching polymers to form continuous filaments, laying these filaments into a web, and then bonding the web through self-adhesion, thermal bonding, chemical bonding, or mechanical reinforcement to create a nonwoven fabric.
5. Meltblown Nonwoven Fabric: The process of meltblown nonwoven fabric production involves: polymer feeding, melt extrusion, fiber formation, fiber cooling, web formation, and fabric reinforcement.
6. Needle-punched Nonwoven Fabric: Needle-punched nonwoven fabric is a type of dry-laid nonwoven fabric. It utilizes the piercing action of needles to reinforce a loose fiber web into a fabric.
7. Wet-laid Nonwoven Fabric: Wet-laid nonwoven fabric involves opening fiber raw materials into single fibers in an aqueous medium, simultaneously mixing different fiber raw materials to create a fiber suspension. This suspension is then transported to a web-forming mechanism, where the fibers form a web in a wet state and are subsequently reinforced into a fabric.
8. Stitch-bonded nonwoven fabric: Stitch-bonded nonwoven fabric is a type of dry-laid nonwoven fabric. The stitch-bonding method uses warp-knitted loop structures to reinforce fiber webs, yarn layers, nonwoven materials (such as plastic sheets, plastic foil, etc.), or combinations thereof to create nonwoven fabric.
Hydrophilic nonwoven fabric: Primarily used in the production of medical and hygiene materials to achieve a better feel and prevent skin irritation. Sanitary napkins and panty liners utilize the hydrophilic properties of hydrophilic nonwoven fabrics.
Nonwoven Fabric Applications Classification:
1. Medical and Hygiene Nonwoven Fabrics: Surgical gowns, protective clothing, sterilization wraps, masks, diapers, household rags, cleaning cloths, wet wipes, magic towels, soft towel rolls, beauty products, sanitary napkins, panty liners, and disposable sanitary cloths, etc.
2. Home Decor Nonwoven Fabrics: Wall coverings, tablecloths, bed sheets, bedspreads, etc.
3. Clothing Nonwoven Fabrics: Linings, interlinings, wadding, shaped cotton, various synthetic leather base fabrics, etc.
4. Industrial Nonwoven Fabrics: Filter materials, insulation materials, cement packaging bags, geotextiles, covering fabrics, etc.
5. Agricultural Nonwoven Fabrics: Crop protection fabrics, seedling raising fabrics, irrigation fabrics, thermal insulation curtains, etc.
6. Other Nonwoven Fabrics: Space cotton, thermal and sound insulation materials, oil-absorbing felt, cigarette filters, tea bags, etc.
