ABSTRACT
Non-wovens are considered as a sheet of fibres, continuous filaments or chopped yarns of any nature or origin formed into web by any means and bonded together by any means, with the exception of weaving or knitting. Non-woven fabric manufacturing process consists of four stages: opening of fibres; web formation; web bonding; and finishing. About 50% of the non-woven fabric production is based on dry-laid web formation process. Spunlaid or spunbond non-woven fabrics are composed of continuous filaments produced by an integrated fibre spinning, web formation and bonding process. Chemical bonding mainly refers to the application of a bonding agent to the web. The whole web may be made of thermoplastic fibres or a small amount of thermoplastic fibres or powder may be blended/sprinkled with non-thermoplastic fibres or higher melting point fibres. Finishing of non-woven fabrics is done to improve the technical functionality and appearance of fabrics.
