A study of sorption kinetics and capacity compared highloft cotton fabrics manufactured from 50 percent bicomponent bonding fibers and 50 percent polyethylene terephthalate (PET), greige cotton, or bleached cotton base fibers. The KRUSS K 12 tensiometer measured sorption kinetics in different fabric directions related to fiber orientation. Important parameters were the effects of the base fibers, fabric structure, and fiber orientation on the sorption properties. Samples based on PET and bleached cotton had better adsorptive capacity than those based on gray cotton due to the presence of neps in the gray cotton, which prevent liquid from penetrating. A thin Struto structure was more open to liquid penetration than a neeld epunched structure. 7 refs.
