Magnetic resonance imaging (MRI) and a pilot-scale laboratory through-air d
ryer are used to study through-air drying of unbacked tufted nylon carpets.
MRI is used to study the effect of the vacuum extraction procedure on loca
l moisture distribution within the carpet and to measure local moisture pro
files during through-air drying where airflow rate is held constant. The ef
fects of several process and carpet construction parameters on drying are d
iscussed.
