Abstract

The rag waste has been opened using "CGC" processes to be used in the production of nonwoven fabrics for various end uses. It is clear that as the fibre length decreases the compression characteristics will be improved. It was found that as the number of beater increases the quality number and (%) damage increased also.
The survey of the methods of production of nonwoven out of textile waste is given. It was found that the coefficient of exploitation (K) for nonwovens out of textile waste ranges between 8% and 12%. The coefficient of variation of nonwoven fabric thickness which is a measure of the uniformity of the non-woven textiles, range between 1.22% and 4.2%.
The strength anisotropy of waste nonwoven fabric is better than that of virgin fibre interlining nonwoven fabrics. The stitch bonded nonwoven interlining show high value (0.700, while needle punched nonwoven interlining show less anisotropy (0.19). The most interesting results are from the fabric out of waste fibres, which show less strength anisotropy value 90.21) than others tested fabrics.
