Abstract
Polyester fabric which may be in the form of a warp-knitted lock-stitched or tricot-stitched tubular construction is compacted by treatment with NO.sub.2 either in the gaseous phase or in solution. The product, after neutralization, washing and crimping is suitable for vascular prostheses. In one form, the compacted product is crimped and bifurcated. Shrinkage in both the longitudinal and transverse directions is at least 30%. The porosity of the fabric is reduced by the compacting treatment.
