A suitable environment is very important for inspection. In
order to speed up the inspection, fabric manufacturer
should provide inspectors with necessary support inloading 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:
