Law of Critical Yarn Diameter and Twist Influence on Yarn Characteristics

The effect of increased twist upon yarn density is explored and a law of critical diameter is postulated. It is suggested that at the time at which a yarn breaks under tensile load the density of the yarn is equal to the fiber density. The influence of twist on contraction is examined and prediction...

Description
Summary:The effect of increased twist upon yarn density is explored and a law of critical diameter is postulated. It is suggested that at the time at which a yarn breaks under tensile load the density of the yarn is equal to the fiber density. The influence of twist on contraction is examined and prediction formulas are given for cotton, woolen, worsted, and rayon yarns.
