The alkali centrifuge value (ACV) quantitatively measures caustic sorption in fibers and is related to the fibers swelling capacity. The ACV decreases when fiber swelling is restrained by crosslinks. In fabrics treated with dimethylolethyl eneurea (DMEU), the magnitude of decrease in ACV depended upon fabric construction and pretreatment. The basket- weave fabrics had lower ACV's, i.e., more restraint to swelling, than the plain-weave fabrics; the mercerized fabrics had lower ACV's than the scoured fabrics. Other data are presented to support the hypotheses deduced from the ACV relationships.
