Zusammenfassung:	PURPOSE:To obtain an interknitted fabric containing a polyurethane-based fiber capable of dyeing at high temperature and pressure and excellent in dimensional stability by using a specific polyurethane-based elastic fiber and optimizing heat set conditions before dyeing. CONSTITUTION:Two-way tricot knitted fabric obtained by interknitting a polyurethane-based elastic fiber having polymer characteristics whose logarithmic viscosity after heat set is 1.8-2.5g/dl with a polyamide and/or polyester-based multifilament is scoured and subjected to relax treatment and immersed in a warm water kept at 70-80 deg.C and controlled to 30% water content by a mangle and subjected to heat set at 160-190 deg.C for 40-50sec by a pin tender and then, dyed at high-temperature of 130 deg.C to provide a dyed product without impairing physical properties such as elongation recovery, curling ratio, shrinkage factor, etc., of washing area.
