We selected our thesis topic on the cutting and sewing department because most of the fault is occurred in these two sections and affect on garments quality. We also tried to identify different types of defects, their causes and remedies. We have mainly collected in cutting section their daily and weekly cutting quality reports and some fault show Major defect and some fault show minor defect and also identified which types of defects mainly occurred and calculate their (%). Some major faults are (Crease mark, oil sport, missing yarn, hole, thick yarn, uneven dyeing, running shade).The final cutting result is: Neps (8.38%), Knitting Hole (7.38%), Dyeing Spot (7.35%), Needle Mark (7.01%), Thick/thin yarn (7.0%), Yarn Contamination (6.70%),Lycra (6.59%),Crease Mark (6.22%),Drop Needle (6.18%),Oil spot (6.15%), Knot (6.11%),Uneven dyeing (5.55%),Off Grain (5.26%), Tron (4.72%), Dirty Spot (4.12%),Selvedge Uneven (2.66%), Miss Print (2.57%).
