This research is mainly concerned with designing fabrics used in heart prostheses (patches , valves frames and vasculars). The woven technique was applied to produce these fabrics, using different constructions (regular hopsack 2/2,twill 1/3 , satin 4 and double weave). One textile material was employed in this research (Lycra covered with polyester) The produced fabrics were treated with Chitosan. Different parameters were studied including, the fabric structure, warp and weft set and their influence on the performance of the end-use fabric and the achieved properties were studied by applying tests; air permeability, water permeability, thickness and weight,
