Title:
CV特性を強化したリヨセル繊維
Document Type and Number:
Japanese Patent JP5491477
Kind Code:
B2
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, meltblowing 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 self bonded nonwoven fabrics.
