A statistical investigation into the determining woven fabric defects that occur on raw terry fabrics during weaving production

Abstract

In this study, the number of specific woven fabric defects occured on raw terry fabrics during weaving production were investigated with statistical process control techniques. Raw fabrics of a selected standart fabric production were inspected for defect detection after weaving operation in a towel production company. Defects were detected by inspection of fabric on a lighted control board by experienced experts. Number of defects were noted on quality control charts. Applying pareto analysis, defects were revealed that formed 80% of total defects. Cause-effect diagrams and p control charts were created and solution suggestions to avoid these defects were presented keeping in mind that eliminating elementary causes, which is 20% of total problems, can resolve 80% of resources of problems.
