- Abstract
Although the rope method is the most simple and economical means of scouring and bleaching greige goods, it also produces longitudinal wrinkles which remain in the bleached fabric and detract from its appearance. A crosslinking treatment prior to rope bleaching can stabilize the fabric and minimize the formation of rope marks. Of the treatments evaluated, either a conventional pad-dry-cure treatment of the desized fabric with dimethylol ethylene urea, or a wet crosslinking treatment of the greige goods with NaOH-dichloropropanol appears to give the greatest improvement in the smooth-drying performance of the rope bleached fabric. Conventional crosslinking of greige goods leads to the formation of an excessively stiff fabric which requires pressure steaming after bleaching to produce a satisfactory hand. Furthermore, because cellulose crosslinking agents seem to react preferentially with starch hydroxyls rather than cotton hydroxyls, there are not sufficient cotton crosslinks formed to cause conventionally crosslinked greige fabric to resist the formation of rope marks. It is necessary to incorporate optical brighteners into all of these crosslinking pretreatments to obtain satisfactory whiteness after bleaching.
