Abstract
A stiff fabric comprises a woven synthetic fabric coated with a latex compound aerated to provide a weight upon application to the fabric of between 0.63-0.89 gms./ml. The compound is pressed into the fabric by a knife blade having a rounded convex lower edge whereby the compound applied to one side of the fabric passes into the interstices but remains substantially clear of the face side. The compound is cured on the fabric in an oven at approximately 149.degree. C. for 45-60 seconds.
