Abstract
The present invention is directed to a lyocell fiber having a high hemicellulose content. The fibers are readily cut into staple lengths and can be spun into yarns with excellent knitting and weaving characteristics which dye exceptionally well. The fibers have a cotton-like denier.
Claims5
A lyocell fiber having a hemicellulose content of between about 13% and about 15%, and having a greater variability in cross sectional diameter and cross sectional configuration along the fiber length compared to variability in cross sectional diameter and cross sectional configuration along the fiber length of lyocell fibers produced by a continuously drawn process.
