                     MODULE 8 : Prepare & Evaluate the Quality Control



           EXERCISE 31 : Identifying defects in fabrics & accessories



            Objectives

           At the end of this exercise you shall be able to
           •  weaving defects
           •  printing and dyeing defects.

           Requirements

           Tools/Materials

           •   Fabric testers, measuring tape
           •   Seam gauges, thread samples

           Job Sequence


           Fabric defects
           1  Weaving defects
               -   Broken ends or picks : Look for areas where warp or weft yarns are  missing, creating weak spots in the
                 fabric.
               -   Floats or snags : Check for loose yarns on the surface of the fabric,  caused by weaving errors or machine
                 malfunctions.

               -   Misaligned or skewed patterns : Examine the fabric for patterns  that are not aligned properly, leading to
                 irregularities in the design.
           2.  Knitting defects

               -   Dropped stitches : Inspect the fabric for holes or gaps caused by  missed or dropped stitches during the
                 knitting process.
               -   Runners : Look for long, pulled yarns caused by knitting machine  malfunctions, which weaken the fabric’s
                 integrity.
               -   Fabric distortion : Check for uneven tension or misalignment of  stitches, leading to distortions in the
                 fabric structure.
           3  Printing and dyeing defects
               -   Off-Registration : Examine printed fabrics for misalignment of  colors or patterns.
               -   Staining or bleeding : Check for colors bleeding into each other or  onto adjacent areas due to improper
                 dye fixation.
               -   Inconsistent color: Look for variations in color intensity or hue  across the fabric surface.
           4  Finishing defects
               -   Creases or wrinkles : Inspect the fabric for uneven or excessive  creasing caused by improper finishing
                 processes.
               -   Stiffness or harshness : Feel the fabric for roughness or stiffness  due to excessive chemical treatments
                 or insufficient softening.
