  • High absorbency lyocell fibers and method for producing same
    Publication number: 20090151881
    Abstract: High absorbency lyocell fibers are obtainable by hydrothermal treatment. The fibers can be treated with water at temperatures of at least 60° C. to provide lyocell fibers that can be formed into a random fibrous plug having a mass of 2 g, a density of 0.4 g/cm3, and a diameter of 25 mm which has a GAT Absorbency (at 15 min.) of at least about 3.7 g/g.
    Type: Application
