Publication number: 20250034807Abstract: Bleached polycrylic acid crosslinked cellulose fibers with reduced furfurai content are disclosed. The reduced furfural content is accompanied by a strong reduction of malodor associated with crosslinked fibers. Methods of furfurai reduction include treatment with hydrogen peroxide in the absence of alkaline or other bleaching agents subsequent to curing polyacrylic acid crosslinked cellulose fibers. Some embodiments of treated polycrylic acid crosslinked cellulose fibers have a furfural content lower than 1.3 ppm. In some embodiments, the reduction of furfural content of the treated crosslinked fibers compared to untreated crosslinked fibers is at least 55%. in some embodiments, furfural content decreases with aging of the treated crosslinked fibers.Type: ApplicationFiled: October 9, 2024Publication date: January 30, 2025Inventors: Angel Stoyanov, Joerg Endres, Holger Beruda, Ludwig Busam
