Abstract
Cotton print cloth and broadcloth were made wrinkle resistant by treating with curbonylbisaziridine (CBA) by the conventional process of padding, drying, and curing. Data are presented for fabric treated with and without the use of an acid catalyst, zinc fluoborate. An aftertreatment with Primenit VS emulsion2 increased the crease recovery angle. Monsanto crease angles of over 300° were obtained with resin add-ons as low as 4.5%. In general the Elmendorf tearing strength was reduced 40-50%. This was improved somewhat by the use of a softener. The finish was quite stable to home laundering. When no catalyst was used in the solution, a reduction in breaking strength was observed after the chlorine bleach and scorch. When freshly prepared CBA solutions containing zinc fluoborate were used. there was no reduction in the strength of fabric after the chlorine bleach and scorch. However, all fabrics containing the finish were discolored in the scorched areas.
