Problems in Jigger Dyeing: A Circular Report

摘要

The jigger is one of the commonly used machines for dyeing cloth. Inherent problems in the use of jiggers are described in this report. Ending is one of such problems. Strike of the dye, its migration characteristics, and exhaustion of the dye bath affect the seriousness of the problem of ending. Some of the other problems are tailing, listing, moire effect and streakiness. Causes of these problems are discussed. Variation in temperature and tension in the fabric processed on a jigger are also responsible for many defects in the dyed fabric. Recent developments in machine design attempt to overcome the operating difficulties which give rise to uneven dyeing. Along with the main design features of these machines, some novel ideas used by the manufacturers in modifying the jigger design are described.
