    Abstract: PROBLEM TO BE SOLVED: To provide a production process for polyester filament yarns of high quality and high uniformity that can stably produce a polyester filament yarn of low-elongation and elasticity with no occurrence of package collap se, poor unreeling, yarn breakage and the like. SOLUTION: An undrawn or partially oriented polyester filament yarn is drawn with a drawing machine equipped with at least a pair of hot rollers to prepare a polyester filament yarn with an elongation modulus of 60-85% and followed by winding up the drawn filament yarn in a pirn form. At this time, take-up tension is maintained in a range of ±

    Abstract: PROBLEM TO BE SOLVED: To provide a warp knitted fabric comprising a two-way tricot or raschel net, useful as a raw material for garments, especially a stretch raw material for sports or inner wears, having higher color developability than those of conventional fabrics, and knitted from elastic yarns and modified polyester yarns having good visibility and high strength. SOLUTION: This warp knitted fabric having high color developability and high visibility comprises a two-way tricot or raschel net knitted from elastic yarns and multi-filament yarns which are formed from a cation dye-dyeable polyester, has a single filament fineness (d) of
