Abstract

Experimental values of heat of fusion for two indigenous polyester fabrics, candidate materials used in sewing ring of an heart valve, were 25.5 and 52.7 J/g while it was 65.3 J/g for an imported Dacron fabric The latter was selected as a reference material in view of its long clinical record. The implications of the observed differences inT g, Tm and per cent crystallinity are discussed and some level III test areas indicated.
