Centre to Selvedge variation is a critical problem in open width fabric processing industry. Although this defects become visible after the dyeing operation, but all other sections are more or less responsible to create this problem in the industry. Here in this paper, different possibility of causes for centre to selvedge variation & how it can be controlled are discussed.
1. Introduction

The main problem faced in continues dyeing range is centre to selvedge variation. Approximately 5-6% fabric are reprocessed / month to overcome this problem. Due to the reprocessing, the processing cost of fabric per meter increases.
