UTILIZATION DE TEXTILE WASTES IN NONWOVENS Part I: Properties of Industrial Needle Punched Nonwovens Out of Textile Wastes.

I he rag waste Iws been opened using "CGC" processeo Lo be used in the production of nonwoven fabrics for various end uses. It is clear that as the i'ibre length decreases the compression characteristics will be improved. It woo found that as the number of beater increases the quality number and (%) damoge increased also. The survey of the methods of production of nonwoven out of textile waste io 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 e measure of the uniformity of the nonwoven textiles, range between 1.22% end 4,2%. The strength anisotropy of waste noiwoven fabric is better than that of virgin fibre interlining nonwoven fabrics. The stitch bonded nonwoven.interlining show high value (0.70), while needle punched nonwoven interlining show less oniaotropy (0.19). The most intersting results ere from the fabric out of waste fibres, which show less strength anisotropy value (0.21) than others tested fabrics.
