Yarn Snarling Testing Aparatus and Method

Summary

A process for measuring snarling properties of a yarn is provided. Firstly a first and a second point of the yarn are held in close proximity, and a portion of the yarn between the two points is of a predetermined length. A predetermined tension force is temporarily exerted to the portion of the yarn, and simultaneously the portion of the yarn is temporarily restricted from twisting when the tension force is exerted. Then the portion of the yarn is released from the tension force such that the portion of the yarn is able to twist freely so as to form snarls thereon. Thereafter, the snarling properties of the yarn are measured by detecting an amount of the snarls thereby formed.
