FILTER CLOTH FOR SOLID/LIQUID SEPARATION

摘要

PURPOSE:To improve water permeability of a filter cloth having high percentage of transfer and high solid/liquid separation performance by nap raising the weft of a woven filter cloth constituted of weft of synthetic fiber crossed to the warp of deformed synthetic fiber filament. CONSTITUTION:Synthetic fiber having >=3X10<3>cm<2>/g specific surface area is used as the weft of fabric for constituting a filter cloth, and synthetic fiber filament having >=1.5 ratio of the dia. of circumscribed circle/dia. of the inscribed circle of the fiber section is used as the warp. Preferred fineness of the fiber is 1-5d, and preferred sectional shape of the fiber is Y shape or H shape. The fabric is constituted of said weft and warp and the raised synthetic fiber obtd. by nap raising the weft are laid by aligning in approximately one direction. A filtration layer is formed from such piles.
