Selected answer:irregularity or unevenness....
Explanation:
I hope the links help////

The mass per unit length variation due to variation in fibre assembly is generally known as "IRREGULARITY" or "UNEVENNESS". It is true that the diagram can represent a true relfection of the mass or weight per unit length variation in a fibre assembly. For a complete analysis of the quality, however, the diagram alone is not enough. It is also necessary to have a numerical value which represents the mass variation. The mathematical statistics offer 2 methods

the irregularity U% : It is the percentage mass deviation of unit length of material and is caused by
uneven fibre distribution along the length of the strand.
the coefficient of variation C.V.%
In handling large quantities of data statistically, the coefficient of variation (C.V.%) is commonly used to define variability and is thus well-suited to the problem of expressing yarn evenness. It is currently probably the most widely accepted way of quantifying irregulariy. It is given by

coefficient variation (C.V.%) = (standard deviation/average) x 100

various faults occuring in the fabric


Explanation:
"The term fabric fault covers all faults occuring in the fabric resulting from previous stages of woven processing."

Fabric faults can be fabric defects, flaws, or imperfections.
One of the meanings of the noun \"fault\" is \"a defect or imperfection; flaw; failing.\"
