Abstract:
1. A method of making an elastomeric composite containing reinforcement cords comprising the steps of (a) applying a twist to a first yarn of 118 to 315 tpm (3 to 8 tpi) in the S or Z direction, (b) gathering a plurality of said first yarns into a first cord and applying an S twist to said cord of 157 to 551 tpm (4 to 14 tpi), wherein the cord twist is greater than the yarn twist, (c) gathering a plurality of said first yarns into a second cord and applying a Z twist to said cord of 157 to 551 tpm (4 to 14 tpi), when the cord twist is greater than the yarn twist, (d) calendering said first and second cords into an elastomer wherein n×TM of S cords substantially equals n×TM of Z cords wherein n is the number of cords and TM is the twist multiplier of the cords as defined by where dTex represents the linear density of the bulk greige yarn, and tpm is the twist of the cord in turns per meter, and wherein no more than 5 S cords or 5 Z cords are adjacent to each other.
