Abstract
The prosthesis is manufactured by knitting a foundation yarn with a high degree of heat-shrinkability and at least one effect yarn which is substantially heat stable, immersing the resulting fabric in boiling water so as to shrink the foundation yarn and thereby reduce its permeability to liquids while not affecting the effect yarn significantly so that it is possible to obtain good velvet effects without resorting to very high overfeed rates for the effect yarn.
