Non woven fabrics and spunbonded fabrics are subordinate. Non woven fabric is a kind of fabric formed without spinning and weaving.

Characteristics and applications of non-woven fabrics. Durability, disposable. Insulated, conductive. Softness, rigidity. Fineness and expansibility. Isotropic, anisotropic.
