KNIT REINFORCING FABRIC

摘要

A knit fabric suitable as a reinforcement for tubular elastomeric articles or a fiber-reinforced composite structure wherein;(i) the fabric comprises a plurality of first filamentary yarns (first yarns) having a tenacity of 2.5-56 g/dtex and a linear density of 222-10000 dtex that form the loops of the knit of the fabric,;(ii) the fabric further comprises at least one second filamentary yarn having a tenacity of 2.5-56 g/dtex and a linear density of 222-10000 dtex that, within a course of the fabric, passes in a helical direction in front of all is first yarns in that course and is intertwined with at least some of the first yarns in an adjacent course, and;(iii) within a course of the fabric, the length of first reinforcement yarn to the length of second yarn is in the ratio of from 1.0:1.72 to 1.0:6.0.
