  • Publication number: 20160280490
    Abstract: A spool comprises a three-dimensional substrate and a core. The three-dimensional substrate comprises a plurality of projections extending outwardly from a plane of the substrate. The spool comprises a first plurality of spirally wound portions and a first plurality of helically wound portions. The substrate is spirally wound around the core to form each spirally wound portion of the first plurality of spirally wound portions. The spirally wound portions of the first plurality of spirally wound portions are located next to each other along a longitudinal axis of the core between a first transversal side edge of the core and a second transversal side edge of the core. The substrate is helically wound around the core along the longitudinal axis of the core to form each helically wound portion. Each helically wound portion extends between two adjacent spirally wound portions of the first plurality of spirally wound portions.

  • Patent number: 9205405
    Abstract: Absorbent articles comprising bleached polycrylic acid crosslinked cellulose fibers with reduced furfural content are disclosed. The reduced furfural content is accompanied by a strong reduction of malodor associated with crosslinked fibers. Methods of furfural 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.
