TIRE-REINFORCING DIP CORD AND PROCESS FOR PREPARATION THEREOF ABSTRACT OF THE DISCLOSURE A tire-reinforcing dip cord composed of nylon 6 and/or nylon 66 fiber is described. The dip cord has (1) a strength at break of at least 8.2 g/d, (2) an elongation of at least 18% under a load of 8 g/d, (3) a gradient not larger than 0.75 in the load-elongation curve immediately before break, and (4) a cord diameter variation ratio (D/Do) (D = cord diameter under a load of 450 g and Do = cord diameter under no load) not larger than 0.65. The dip cord is prepared by treating a nylon 6 and/or nylon 66 cord yarn with an adhesive wherein at least one of the following processes A, B and C is employed: (A) prior to the adhesive treat- ment, the yarn is heat-treated and then cooled, (B) the adhesive treatment is carried out under elongation of at least 3%, and (C) as the adhesive, a liquid mixture of a resorcinol/formaldehyde (R/F) condensate and a rubber latex is used, in which at least 20 wt.% of the conden- sate has a R/F molar ratio of 1/1.9 - 1/1.
