Leaders - Are They Useful in Jigger Dyeing

摘要

A large quantity of fabrics in a textile mill is dyed using different types of colors. The majority of these fabrics are generally dyed in small batches on jiggers, either directly or by the pad-jig process. When dyeing on a jigger, a small length of fabric is first wound separately and then transferred to a jigger or alternately a small length is wound directly on a jigger from a pile of fabric. The length of such a jigger batch (also termed a beam) is about 500 meters. Some mills use leaders attached to the two ends so that the cloth in the batch is not damaged, but this leads to waste of cloth used as leader. No data are available on the extent of damage due to this cause and of the waste of cloth used as leaders. Some mills, therefore, do not use leaders on both the ends of a jigger batch. Data collected on this issue from different mills are presented in this research note. Effort has been made to bring out the effect of different factors on this type of damage.
