TITLE METHOD FOR MEASURING YARN SHRINKAGE AND CRIMP DEVELOPMENT ABSTRACT OF THE DISCLOSURE A method for measuring continuously shrinkage and crimp development in a long continuous sample of yarn involves the steps providing a zero-tension loop, applying a standard tension, then developing crimp in a single downward pass through a hot air chamber providing a second zero-tension loop and thereafter retensioning it. The shrinkage and crimp development is calculated from differential speeds of rolls advancing the yarn. C-2083A
