FLAT MULTIFILAMENT-YARN TEXTILE

摘要

Flat multifilament-yarn textile having excellent characteristics of low air permeability, show-through prevention capability and/or water/sweat-absorbing capability is textile including multifilament yarns each of which is formed of plural artificial filaments as the warp and weft and has a flat cross-sectional shape. On both sides of the longitudinal centerline in the flat cross section, at least more than three swollen portions per one side, outwardly swollen from the longitudinal centerline, and more than two constricted portions per one side, formed between the swollen portions, are formed substantially symmetrical with respect to the longitudinal centerline. A cross-sectional flatness expressed by a ratio (B/C1) of a length (B) in the longitudinal centerline to a maximum width (C1) in the direction perpendicular to the centerline direction is within a range from 2 to 6 and has a cover factor of 800 to 3,500 as the textile as a whole.
