Woven polyester upholstery fabrics, comprising multilobal filament yarn warp and textured yarn weft, were heat‐set at different temperatures. The weft of these heat‐set fabrics was dyed at high temperature (130 °C) using dyes of small and large molecular size, respectively, using both separate and competitive dyeing methods. The results show that the difference in dye uptake between substrates heat‐set at immediately adjacent temperatures is higher in competitive dyeings than in separate dyeings. It has also been observed that dye uptake differences are always higher for dyes of large molecular size than for dyes of smaller size.
