Abstract:
|
Inconsistent fabric preparation may result in uneven
removal of impurities and soils which can cause unlevel or
inconsistent application of dyes and chemicals in dyeing
and finishing. Currently, impurity or extractable testing
of prepared fabric may require several days time and
precisely followed procedures to obtain accurate
quantitative results.
Because of these time and effort requirements, many wet
processing plants do not routinely test extractables.
Therefore, a precise and fast method for quantitatively
determining .extractable levels would enable textile wet
processors to better evaluate and control preparation thus
possibly reducing costly inconsistencies in dyeing and
finishing.
This thesis investigates an alternative way of
measuring extractable levels of cotton and polyester/cotton
fabrics using Near-Infrared Analysis and provides an
understanding of the methods NIRA uses for quantitative
measurement.
