PURPOSE:To separate a large number of colloid solutions each comprising a small amount in an extremely easy manner, by applying water guiding processing to a fabric comprising fibers each having recessed parts formed to the surface thereof in the axial direction. CONSTITUTION:A polyester or polyamide synthetic fiber multifilament is constituted of monofilaments each having at least one of a continuous groove shaped recessed part provided to the surface thereof in the fiber axis direction. The fineness of the monofilament is 1-5d, the total fineness of the multifilament is 50-100d and twisting is applied so as to adjust the number of twists to 100- 2,000 times/m. This multifilament is used to obtain a fabric wherein the sum of warp yarn density and weft yarn density is 210 piece/inch or more. Water guiding processing is preliminarily applied to this fabric. |
