1. A tightly-woven, low-porosity prosthesis, to which tissue can adhere, comprising:
- a woven double-velour fabric material formed from a warp yarn and a fill yarn and having loops formed from loop yarns about the fill yarns, the yarns being of a yarn material to which growing tissue can adhere;
the warp yarn being one of untexturized, unshrunk yarn and texturized, shrunk yarn, said fabric having loops of said texturized yarn on both surfaces thereof for facilitating adherence of tissue to said prosthesis.

Abstract
A woven double-velour fabric of synthetic fiber provides an excellent structure for ingrowth and adhesion of tissue thereto and can be woven tightly enough so that preclotting may be omitted is so desired. The features recited are achieved through the use of appropriate combinations of preshrunk, texturized yarn with unshrunk, untexturized yarn.
