  • Dryer sheets including bicomponent fibers
    Patent number: 7838449
    Abstract: A dryer sheet substrate is provided having improved loft and reduced fuzz wherein the substrate comprises relatively low denier bicomponent fibers. The bicomponent fibers may comprise two or more polymers having different melting temperatures, with the relatively lower melting temperature polymer making up at least a portion of the outer surface of the fiber. Upon heating to a sufficient temperature, the lower melting temperature fibers may soften and melt, providing bonding at crossover points of the fibers in the laid web. The web indicates advantageous characteristics with respect to thickness (loft), fuzz factor and ability to absorb a fabric treating composition.
    Type: Grant
