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.
Claims25
Staple fibres comprising a plurality of solid cellulosic regenerated viscose fibres of standard viscose, substantially all of said fibres having substantially the same cross-sectional shape, each fibre having a decitex in the range of 0.5 to 5 and having three limbs, each limb having a length-to-width aspect ratio in the range of 2:1 to 10:1.
Staple fibres comprising a plurality of solid cellulosic regenerated viscose fibres of standard viscose rayon, substantially all of said fibres having substantially the same cross-sectional shape, each fibre having a decitex in the range of 0.5 to 5 and having four limbs, each limb having a length-to-width aspect ratio in the range of 2:1 to 10:1.
A cellulosic regenerated viscose fibre of standard viscose rayon, said fibre having a decitex in the range of 0.5 to 5 comprising three limbs of substantially the same cross-sectional shape, each limb having a length-to-width aspect ratio in the range of 2:1 to 10:1.
A cellulosic regenerated viscose fibre of standard viscose, said fibre having a decitex in the range of 0.5 to 5 comprising four limbs of substantially the same cross-sectional shape, each limb having a length-to-width aspect ratio in the range of 2:1 to 10:1.
A textile article including a plurality of solid cellulosic regenerated viscose staple fibres of standard viscose rayon, substantially all of said cellulosic regenerated standard viscose rayon fibres having substantially the same cross-sectional shape, each fibre having a decitex in the range of 0.5 to 5 and having three or four limbs, each limb having a length-to-width aspect ratio in the range of 2:1 to 10:1.
