Fabric roll measurement during an inspection
Fabric rolls are controlled following the widely known 4 points system; however, there are also other details checked during an inspection, such as the product’s conformity to the client’s requirements. This included the measurements, etc. How does the fabric rolls measurement work during an inspection? What are its limitations?
Fabric rolls measurement procedure
Fabric rolls length measurement
All fabric rolls factories should have this specific machine (as per the above picture) which efficiently counts the number of meters (or yards) per roll.
Fabric rolls width measurement
The fabric rolls width measurement is taken by using the measuring tape. The final measurement indicated in the inspection report by the quality inspector is based on the minimum width measured from three different locations: at the beginning, in the middle and at the end of the fabric roll.
Limitation to the fabric rolls measurement during an inspection
The calibration of the machine can affect the measurement of the length of the fabric. There is a tolerated discrepancy of more or less 1%, give or take, otherwise the buyer should mention its own tolerance levels in conveying measurements.
For knitted fabric and some elastic or smooth woven fabric, the use of inspection machine is not applicable.
The measurement of the fabric width can be different along the roll, therefore the measurement result may differ if taken elsewhere than at the beginning, in the middle and at the end of the fabric roll.
In fact the manufacturing of fabrics is quite complex, there are always discrepancies in terms of length and width. Buyers should be precise with their measurement requirements, if they vary from the usual procedure of their third party inspection partner, to ensure the fabric roll inspection is based on the same criteria.
And you: how do you proceed with the fabric rolls measurement during an inspection?
