Abstract
Provided is a method of manufacturing a hybrid dip cord, which includes: a step of preparing one nylonyarn or nylonyarn and one aramid yarn; a step of producing a primarily twisted yarn by applying a twist of 200 to 500 TPM by inputting one nylonor nylonyarn longer than the aramid yarn; a set of cabling the primarily twisted yarn as two to apply a twist of 200 to 500 TPM to thereby produce a raw cord; and a step of dipping the raw cord in an adhesive liquid and heat-treat the raw cord, in which the nylonor nylonis heat-shrunk so that the length of the nylonor the nylonbecomes equal to the length of the aramid yarn.
