Nonwoven fabric is a fabric-like material made from lengthy fibers, bonded together by chemical, mechanical, heat or solvent treatment. In simple terms, they are textiles made from fibers or threads joined together without weaving. Nonwoven materials classically lack strength unless densified or toughened by a backing. In recent years, nonwovens have become an alternative to polyurethane foam.Nowadays nonwoven fabrics are mostly used as home furnishing fabrics. Nonwoven fabrics are described as sheet or web structures bonded together by entangling fiber or filaments (and by perforating films) mechanically, thermally or chemically. They are flat, porous sheets that are made directly from separate fibers or from molten plastic or plastic film. They are not made by weaving or knitting and do not require converting the fibers to yarn. Typically, a certain percentage of recycled fabrics and oil-based materials are used in nonwoven fabrics. The percentage of recycled fabrics varies based upon the strength of material needed for the specific use.
