Abstract

The invention is lyocell fiber characterized by a pebbled surface as seen at high magnification and having a variable cross section and diameter along and between fibers.
The fiber is produced by centrifugal spinning, melt blowing or its spunbonding variation.
The fibers can be made in the microdenier range with average weights as low as one denier or less. The fibers have inherently low gloss and can be formed into tight yarns for making fabrics of very soft hand. Alternatively, the fibers can be formed into selfbonded nonwoven fabrics.

Claims (5)

1. A lyocell nonwoven fabric formed by depositing a multiplicity of strands of a cellulose solution on a receiving surface and then regenerating the cellulose.
2. The lyocell nonwoven fabric of claim 10 in which the fibers are self bonded.
3. The lyocell nonwoven fabric of claim 10 in which the fibers are bonded by a method consisting of hydroentangling, adhesive binders, and by combinations of these methods.
4. The lyocell fabric of claim 10 in which the cellulose solution strands are formed by a melt blowing process.
5. The lyocell fabric of claim 10 in which the cellulose solution strands are formed by a centrifugal spinning process.
