ABSTRACT:
Temperature adaptable fibers are provided in which a polyol/glyoxal based crosslinking system is used to create a water-insoluble polyacetal coating. The formaldehyde release properties characteristic of methylolamide finishing agents is avoided. The non-catalytic reaction utilizes stoichimetric amounts of sulfonic acids to derivatize the polyols which in turn react with the glyoxal to form a water-insoluble polymer. The material also possesses improved properties relating to soil release, durable press, resistance to static charge, abrasion resistance, pilling resistance and water absorbency.
