Textile manufacturing is a complex process and it is affected by various parameters. Most of the defect in the fabric is either highlighted or covered in especially in dyeing department. We are follow in this experiment is to identify the important objectionable defect in the terry towel produced in the winch Thies dyeing machine. This research work is done for preventing the defect in processing & weaving department (excluding spinning department). This study aims to report a root cause analysis of the major defect. This study helps in root cause analysis of the entire process in reducing the defect. It has been reported by many others that careful consideration of process parameter helps technical person to ensure the same faults do not occurs.This study reviles important process parameters such as pretreatment and its effect on absorbency to make uniform dyeing. This study tries to found the terry towel dyeing defect such as uneven dyeing, staining, lintting, shearing, bowing and holes and how we can minimize and neglect this faults to taking remedies. This report contains work done by various workers and technician in dyeing. Experiment conducted in "Thies" dyeing machine clearly shows how to reduce major objectionable defect in terry towel dyeing. This report contains the important content of parameters and their effect in the reducing the defect significantly. This project is able to give a deep concept about terry towel dyeing faults in soft flow dyeing machine, causes and their remedies and carried out to minimize the dyeing defect by taking particular corrective action Thus, this study enrich knowledge on dyeing, produce faults free terry towel in modern textile plant.
