Divide the sides of the first bundle in half so that it’s the shape of an X. Cut a second bundle of yarn into shorter lengths than the first (mine were 4″ shorter) and tie.

The bundle type yarn dyeing machine is designed to process yarns solely for manufacture of denim, and its rational arrangement and use of specific dyes can achieve excellent dyeing results.

The properties of the dyed top were measured using SIROLAN-TENSOR bundle strength tester, and the impact of its damage resulting from dyeing on spinning and yarn quality was analyzed.
