The paper describes the effect of structure on moisture regain and dye uptake of copolyester fibers of poly(ethylene terephthalate) and poly(hexamethylene terephthal ate), poly(octamethylene terephthalate), and poly(decamethylene terephthalate). The increase in the methylene groups per repeat unit of copolyesters resulted in an increase in moisture regain and dye uptake. The diffusion coefficient values for dye uptake in copolyester fibers containing decamethylene groups were exceptionally high.
