New method for raising high-quality fabrics

This article describes the development of an innovative method for raising the surface of high-quality fabrics. The method consists of replacing the natural teasels, currently used, with experimental metal teeth, which do not damage the fabric and reproduce the same effect as natural cards. Literature on the subject contains several examples of artificial metal teeth, which have the advantage of a longer life than the natural ones, however, some can mark the fabric along the warp, if not properly sized. The study in question was based on both experiment and theory, by simulating a flexural load on the barb wire and evaluating its rigidity. Excellent results have been obtained from various tests, and have led to the construction of a new industrial fabric-raising machine.
