  • Patent number: 7572840
    Abstract: The present invention relates to a method for manufacturing super-absorbent polymers, comprising providing a reaction mixture which comprises at least a first monomer and a second monomer and a radical-forming polymerization initiator, and subsequently causing the monomers to polymerize under the influence of an energy source, wherein radical formation occurs and the polymerization is started, wherein the first monomer is neutralized with an inorganic base before polymerization, in addition to the manufactured super-absorbent polymers. The invention further relates to a method for applying a coating of super-absorbent polymers to a carrier.
    Type: Grant

  • Patent number: 6576338
    Abstract: A method for manufacturing a yarn containing superabsorbent fibers of polyacrylate, wherein said superabsorbent fibers are blended with supporting fibers of a material stronger than that of the superabsorbent fibers so as to form a sliver from a blend of said fibers. The sliver is spun into a yarn by using an open end spinning method, wherein the fibers of the sliver are individualized. Subsequently the fibers are fed in an air flow to a rotating spinning space, from where the yarn is spun.
