ABSTRACT:
Viscose filaments, preferably in staple fibre form, which have a decitex of less than 5.0 and a multi-limbed cross-section, the limbs having a length-to-width aspect ratio of at least 2:1. Examples of multi-limbed cross-sectional shapes are Y-, X-, H- and T-shapes. The fibre can be formed into woven, non-woven or knitted fabrics, and is especially useful for absorbent products.
