A treating agent for bonding a polyester fiber and a chlorosulfonated polyolefin compound, which consists of a resorcinol/formaldehyde/latex mixture, wherein: 1) the molar ratio of the resorcinol to the formaldehyde is from 1/0.1 to 1/5, 2) the polymer component of the latex is a 2,3-dichlorobutadiene-containing polymer, 3) the weight ratio of the solid content of the latex to the sum of the resorcinol and the formaldehyde is from 1/100 to 1/1, 4) the amount of the 2,3-dichlorobutadiene-containing polymer solid content of the latex in the resorcinol/formaldehyde/latex mixture is from 5 to 50 wt%, and 5) the amount of a surfactant in the resorcinol/formaldehyde/latex mixture is from 0.5 to 2.5 wt%.
