Abstract (en)
[origin: JPS6433233A] PURPOSE: To obtain warps that give woven fabrics having excellent homogeneity and physical properties by sizing incompletely drawn multifilament yarns, drawing them simultaneously as they are preliminarily dried, then fully drying them and winding up them on the warp beam. CONSTITUTION: Multifilament yarns made of a synthetic thermoplastic resin are sized by allowing the yarns to pass from the feed roller 1 via the sizing areas 2-6, then the preliminary driers 7, 8 to effect the preliminary drying of the sizing agent and drawing simultaneously. Then, the yarns are dried in the drier 9 and wound up around the warp beam 11. In a preferred embodiment, the drawing is carried out by the difference in the peripheral velocity between the final rollers 5, 6 in the sizing zone and the drying cylinder 10 in the drying zone.
