Fabric Quality Inspection:

The quality of a final garment depends on the quality of a

fabric when it is received as a roll. Even the most outstanding

manufacturing methods cannot compensate for defective materials.

Normally, 10% of the rolls that are received are evaluated based on

a four-point system. This way, fabric related quality

problems can be avoided before it is put into production'

Four- Point System:

Amount to select: Inspect at least 10% of the total rolls of the

shipment.

Selection of rolls: Select at least one roll of each color. If

more than one role must be selected, then choose the additional

roles in proportion to the total number of roles per color

received.
