Two cotton knitted fabrics, one of honeycomb and the other of Sinkerbody structure, were durable press finished with dimethy lot dihydroxyethylene urea using three techniques, viz., Pad-cure, Moist-cure, and wet-fix treatment with and without the polymeric stiffening additive Daikanol AMH in the treatment bath. Scanning and transmission electron micrographs of finished knitted fabrics showed that the finishing conditions employed in each technique have a profound influence on the extent of swelling and uniform distribution of crosslinks as compared to the pad-cure and wet-fix treated samples. The use of the polymeric stiffening additive Daikanol AHM in wet-fix treatment bath gave a mixed cross section of both the collapsed and swollen structures with predominance of the latter. -- AATA
