Nonwoven fabric structures are made from fibre webs by mechanical, chemical, thermal or solvent bonding of the fibres or by interlocking the fibres by a needling process. The term non woven does not include felts made of wool fibres. With the development of man made fibres and in particular the synthesis of thermoplastic fibres, technologies have evolved and made possible the large scale production of nonwoven fabrics.
The nonwovens are classified as:
- Paper disposables
- Bonded fibre webs and fusible
- Spun-bonded webs
- Needle- punched fabrics
Nonwoven fabrics are made from both staple and filament fibres. Nonwoven fabrics are easy to sew. They have no grain and do not ravel. Marketed extensively for both durable and disposable items, nonwoven fibre webs range from throwaway diapers to blankets, from industrial filters to tea-bag covers.
Uses of non-woven fabrics
Disposable items: Hospital sheets, gowns, headrests for planes, towels, diapers, wipes, filters, tea-bag covers etc.
Durable items: Interlining, coated fabrics, blankets, carpet backings etc. Disposable products were defined as products made to be disposed off after a single or limited number of uses for example disposable diapers, towels, teabag cover. Some items are disposable not because of their durability because of their purpose. Medical gowns, airplane headrests might withstand multiple uses but for sanitary reasons they have limited use periods.
