PURPOSE:To obtain the titled polyester material excellent in the adhesivity with rubber by treating a polyester material with a treating liquid containing an epoxy compound and a melamine based compound before a thermal treatment. CONSTITUTION:A total of 3-50wt% of an epoxy compound (e.g. glycerin diglycidylether) and a melamine based compound (e.g. melamine-formalin resin), 20- 70wt% of a smoothing agent (e.g. maineral oil) and 10-50wt% of an emulsifier are dispersed in water to obtain a treating liquid. Then, after a polyester material is immersed into said treating liquid and then, undergoes a tense or relaxed heat treatment at 100-250 deg.C for 0.5sec.-several sec. |
