| Abstract:In this paper, the morphology and drainability of trilobal viscose fibers and ordinary viscose fibers which have the same fineness wereanalysed. The effect of the contents of two kinds of fibers on the physical and filtration properties of the filter paper were also studied. The results showed that when the content of viscose fibers less than 50%, the average pore size, air permeability and burst strength of the sheet had little difference, but the thickness of the sheets containing trilobal viscose fibers was higher than the sheets containing ordinary viscose fibers. With the increase of trilobal viscose fibers, the filtration resistance of the sheet declined and the contaminant holding capacity increased, but the filtration efficiency declined meanwhile. When the content of viscose fibers was 30%, the contaminant holding capacity of the sheet containing trilobal viscose fibers was 1.28 times higher than that containing ordinary viscose fibers, and the filtration efficiency was no significant different. |
