When a manufacturing process results in a defective
product it is important to discover how, why and where the fault
has occurred. Corrective actions may then be taken to prevent repetition.
Salvage options may also be considered.
By separating out and examining individual components
of unsatisfactory products, the nature of the fault and the likely
stage at which it occurred can be identified.
It may also be necessary to determine whether
salvage of the affected goods is possible, particularly where large
quantities are involved.
Examples of manufacturing faults which can
be identified are;
Marks, stripes, stains, colouration effects,
blend irregularities, yarn mixes, finishes, batch variations, stress
failure, chemical, mechanical or biological damage.
The correct analysis of returned goods is vital
to any supplier or retailer. Knowing the difference between isolated
cases of misuse and genuine large scale product failure can determine
the response of parties concerned, be they the manufacturer, supplier
or final consumer. Faults such as holes, marks, stains, shrinkage
or physical failure can be skilfully examined and their likely
cause established. Degradation and premature wear may also be assessed
and occurrences such as microbial attack (mildew), enzyme digestion,
mechanical damage etc. can be positively recognised and recorded.
Such features as;
Premature wear, pilling, holes, shrinkage,
soiling, degradation and colour change can all be evaluated and
the fitness for purpose of the original material determined.
