Non woven Fabric is a fabric-like Product created from long fibers, glued along by chemical, mechanical, heat or solvent treatment. Non woven Fabric is neither woven nor knitted. Non woven is generally produced by putting small fibers together in the variant of a sheet or web and then binding them either mechanically or chemically with an adhesive.
Non woven Products are traditionally less strong due to not knitted. In recent years, non woven have become an alternative to polyurethane foam. Non woven fabric is broadly Explained as sheet or web structures glued together by entangling fiber or filaments (and by perforating films) mechanically, thermally or chemically. It is flat, porous sheets that are made directly from independent fibers or from molten plastic or plastic film. It is not manufactured 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 non woven fabric. The percentage of recycled fabrics vary based upon the strength of material needed for the specific use.
Non woven fabric is engineered fabrics that may be a limited life, single-use fabric or a very durable fabric. Non woven fabric provides specific functions such as absorbent, liquid repellent, resilience, stretch, softness, strength, flame retardant , washable, cushioning, filtering, bacterial barrier and sterility. These characteristics are often combined to create material suitable for specific work, while achieving a good balance between product use-life and cost. It can mimic the appearance, texture and strength of a woven fabric and can be as bulky as the thickest padding. In combination with other materials it provides a spectrum of products with diverse properties, and is used alone or as components of apparel, home furnishings, health care, engineering, industrial and consumer goods. Non-woven fabric has its characteristics, which are as follows:
