Abstract

Because of the importance of accuracy in measuring and estimating yarn crimp ratio in woven fabrics, non classical methods were searched for. In this paper mathematical formulate were derived to express yarn crimp ratio in terms of weave structure, yarn spacing, and yarn diameter. It is discriminated between floated weaves and extended weaves. In floated weaves yarn spacing is constant and equal to yarn spacing at the point of intersection. In extended weaves, yarns are separated only at points of intersection. To increase accuracy and safe effort and time consumed in measuring yarn crimp ratio is determined by weighing crimped yarns instead of decrimping them.
