The Empirical Modeling of Snarling in Staple Yarn

An empirical model is proposed for the snarling behavior of steamed staple yarn. This model helped in developing the scientific understanding of various stages of snarl formation and snarl removal. Equations for each process were formed, that helped in getting the relation between count, twist multiplier, tension and length of yarn. Stress at which snarl formation started, could be removed (if snarl is already present in the yarn) and was found to be different for yarns with different parameters such as count, twist etc. The derived equations involving critical stress, count and twist multiplier predicts the tension level that should be maintained to prevent snarl formation and the tension required to remove the snarl, was already present in the yarn .
