Guidelines for Fabric Inspection Procedure

Fabric Inspection Procedure

Fabric Inspection:


Fabric inspection examining machine with variable speed control overhead lighting (daylight bulbs) and yardage county the machine must be clean with no excess oil and sharp edges to damage the fabric.  How much fabric inspection. It is the supplier’s responsibility to 100% inspects fabric inspection procedure  prior to delivery to the garment making factory. The garment making factory should inspect 10% of roll from each delivery at random this should include all colures and dye lots within a delivery. The results show a high fault rate. The additional 15% of rolls should be inspected. If these fail, the delivery must be either rejected or 100% inspect. A high fault rate is defined as average fault rate in excess of 28 points per 100 square yards.


Fabric Inspection Procedure :


  1. At the beginning of each roll a 6’’ fault width cutting should be taken as a colour reference and checked for side ceptre and side to side shading. This fault width cutting must be labeled with the fabric inspection procedure reference number or name. Batch number, piece number, color name, color number and date.
  2. The width of the fabric between the stenter pins must be measured and compared with the given minimum useable width.
  3. Each roll checked should be stopped at least 3 times during inspection (beginning, middle and end) at the these stops, side to centre and side to side shading should be assessed. End to shading must be checked by comparing the full width cutting to this point in the roll also the cut able width (between  stenter pins) should be measured.
  4. The cut able width should be recorded on the inspection report as should any color shading detected (see comment section).
  5. The garment making factory should check the fabric length stated on the price ticket against the actual length or roll for variance. Both values should be recorded on the inspection sheet.
  6. During inspection the fabric inspection procedure should be checked for defects which are rated on the 4 (four) point system. As follows:

                             Flaws up to 3” in length                 =          1 point
                             Flaws up to 6” in length                 =          2 point
                             Flaws up to 9” in length                 =          3 point
                             Flaws over 3” in length                  =          4 point

  • The maximum penalty for any running yard (36” x fabric width) must be not be more than b4 points.
  • Flaws in both warp and weft received equal points
  • All holes, regardless of size must be penalized 4 points
  • No more than 2 joins per fabric roll are allowed
  • The average point value per shipment should not exceed 28 points per 100 square yards
  • Individual rolls exceeding 40 points must be rejected. 

  1. All defect points must be recorded in the inspection report, in addition the location of all defects must be marketed at the right selvedge of the piece.

How To Calculate Point Per  Square Yard

Conclusion:


After the fabric inspection procedure is completed calculated the average points value per 100 square yards. Yards by totaling the points and dividing by the number of piece inspected.This will be the final points total for the inspection.
