Abstract
A recurability test, consisting of a standard ironing to impart a crease, followed by laundering and visual rating of the remaining crease, was developed and applied to cotton fabrics which had been treated with combinations of a methylol crosslinking reagent and a polycarboxylic acid. These fabrics were recurable to a much greater extent than fabrics treated with a conventional metal salt catalyst. A series of ten methylol reagents, when used with polycarboxylic acids, showed a direct relationship between recurability and wrinkle-recovery angle in the treated fabrics. Dimethyloidihydro xyethyleneurea was the best of these reagents in both respects.
