Inserting a lower melting polyamide yarn between plies of nylon 66 yarn improves the
appearance retention (AR) of carpet subjected to foot trafficking. However, the severe
conditions associated with a commercial Beck dyeing process—water temperatures held
close to the boil for several hours and unremitting physical rubbing of the heavy, wet
surface—affect wear performance. Because Beck dyeing is preferred for contract carpet
constructions, i.e., for use in schools, airports, hotels, hospitals, etc., where wear
performance is of paramount importance, a low-melt inserted carpet’s ability to retain its
improved wear performance following the rigors of dyeing raises important questions. A gas
chromatographic method is developed to quantify the amount of insert yarn present in these
carpets. Measurements taken from carpets sampled both before and after the Beck dyeing
show that the loss of low-melt polyamide with dyeing is minimal. While these inserted
carpets exhibit poorer AR performance under the extreme dye conditions of temperatures
and dwell times, they outperform controls lacking the insert yarns. The slight performance
deterioration likely results from a combination of redistribution of the low-melt material and
the continual surface brushing during the dyeing operation.
