A suitable environment is very important for inspection. In
order to speed up the inspection, fabric manufacturer
should provide inspectors with necessary support in loading
and unloading fabric rolls.
All fabrics are to be inspected on an inspection frame with
a variable speed motor and proper lighting.
The fabric will be inspected at a speed that is compatible
with the fabric quality, but should never exceed:
25 yards/meter per minute for solid colors;25 yards/meter per minute for solid colors;
15 yards/meter per minute for printed/ pattern fabrics;.
The fabric inspection quantity depends on the fabric types:The fabric inspection quantity depends on the fabric types:
about 1,500 to 2,000 yards per day;

InspectionInspection ProcedureProcedure –– Fabric WidthFabric Width
Cuttable width will be checked at minimum three
ti d i th i ti f ll (10 d ftimes during the inspection of a roll (10 yards from
beginning, middle and 10 yards from end of the roll).
Assign 4 point (4-point system only) to each linear
yard of fabric where the cuttable width is less than they
minimum specified.
InspectionInspection ProcedureProcedure –– Fabric LengthFabric Length
Fabric length can be measured by a meter which is set
up on the fabric inspection machine. Otherwise, the
lt t b t if th f b i l th iresult may not be accurate if the fabric length is
measured manually on a table, particularly for knit
fabrics.
If a fabric roll length is 2% shorter from the ordered
ticket it may be rejected. Penalty points will not be
i d f ll l th i ti b t it h ll bassigned for roll length variation, but it shall be
included in the inspection report.
