Nonwoven fabrics are broadly defined as sheet or web structures bonded together by entangling fiber or filaments (and by perforating films) mechanically, thermally or chemically. They are flat or tufted porous sheets that are made directly from separate fibres, molten plastic or plastic film. It is a flexible, easy to fold and lightweight material and is washable and sterilisable. It is a barrier against bacteria and, in fact, is used in the production of surgical masks. Woven fabrics are created by weaving yarns. They are often woven together on a loom that holds yarns in place as the weaving process happens. Woven fabrics have a warp and a weft, which determine the direction of the weave. Nonwoven fabric is composed of oriented or random fibers, is a new generation of environmentally friendly materials, with moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, colorful, inexpensive, recyclable and other characteristics.
