Non-woven textiles are those which are neither woven nor knit, for example felt. Non-wovens are typically not strong (unless reinforced by a backing), and do not stretch. They are cheap to manufacture.
A textile structure held together by interlocking of fibers in a random web, accomplished by mechanical, chemical, thermal or solvent means. Generally, crimped fibers that range in length from 0.75 to 4.5 inches are used.
Fabrics made directly from individual fibers that are matted together by forming an interlocking web of fibers either mechanically (tangling together) or chemically (gluing, bonding, or melting together).
In General, A Textile Structure Made Directly From Fibre Rather Than Yarn. Fabrics Are Normally Made From Extruded Continuous Filaments Or From Fibre Webs Or Batts Strengthened By Bonding Using Various Techniques: These Include Adhesive Bonding, Mechanical Interlocking By Needling Or Fluid Jet Entanglement, Thermal Bonding And Stitch Bonding., Note: Opinions Vary As To The Range Of Fabrics To Be Classified As Nonwoven.
