PRODUCTION OF HIGH STRENGTH CORD AND FABRIC

摘要

The present invention reveals a process for manufacturing a high strength woven fabric that is particularly suitable for use as a tire reinforcement which comprises: (a) drawing a polymeric yarn to a draw ratio that is 70% to 99% of the draw ratio that would fully draw the yarn to produce an optimally drawn yarn; (b) twisting at least two of said optimally drawn polymeric yarns into a cord; (c) weaving a plurality of said cords into a greige woven fabric; and (d) stretching and relaxing said greige woven fabric under conditions sufficient to reduce the denier of the cords in said fabric by 1% to 10%.
