The objective of this study is to investigate the elution characteristics of the partial dispositioned hollow nylon filament and the mechanical properties of the eluted fabrics according to the weight reduction conditions. For this purpose, the partial dispositioned nylon/PET composite filament, SDY 70d/48f was prepared, and warp beam was also prepared on the sizing machine using these yarns. Four kinds of woven fabrics were designed with different warp and weft densities and these fabrics specimens were eluted with weight reduction conditions of two kinds of NaOH concentration (30, 40g/l), three kinds of weight reduction temperature (50, 60, $85^{\circ}C$) and two kinds of weight reduction time (30, 60min). The eluting rates of these fabrics specimens were analysed with various weight reduction conditions. The eluting characteristics of these fabrics were discussed with the cross-section of nylon hollow filament measures by SEM. Finally, the mechanical properties of the partial dispositioned hollow nylon fabrics were measured and discussed with various weight reduction conditions.
