Abstract
Abstract This invention relates to the impregnation of spaced courses of yarn in a fabric with a material which is not visible under daylight but which is visible only when subjected to ultra-violet light, so as to provide guide lines for cutting, or measuring indicia to enable visual counting of the number of yards of cloth in a roll from the end thereof without the necessity of unrolling the bolt.
