MATERIAL FILTRANT DDIN FIBRE TEXTILE

摘要

Material comprises a double cloth, with warp of polyester filament and weft of polyamide filament twisted with discontinuous polyamide fibre threads of 33-77 metric twisting coefft. The warp-weft thickness ratio is ca. 2.85 while the warp-to-filament and the warp-to-fibre thickness ratios are 1.30-1.95 ano 0.73-1.10. The material can be used to separate e.g. ash from pneumatic gas lines at coal-fired power stations.
