Major and Minor Defects in Garment Production-1

Some very good definitions of Major, Minor and Critical Defects can be found Here.

Major, Minor and critical Defects are the part of classification given to the flaws while inspecting the fabrics or garments.The classification depends upon the severity of the defect and forms a basis of acceptance or rejection of the lot.

Consideration in classifiying the defects as major or minor is taken on the basis of the affect on saleability of the garment, location of the defect and conspicuousness of the defect.

In this document , the location of the defect( the zone) is shown in various garments which make a defect serious or insignificant. There is also a comprihensive list of the critical defects.
An analysis of Fabric defects according to their severity as major or minor can be found in this document.

This document is in the form of a contract but it deals brilliantly with all the quality issues including the defects.

The Following is an indicative list that can be followed to ascertain if a defect is a minor or a major defect in a garment:
