LYOCELL FIBERS HAVING ENHANCED CV PROPERTIES

PROBLEM TO BE SOLVED: To provide lyocell fibers having pebbled surfaces and variations in cross section and diameter along and between the fibers.SOLUTION: The lyocell fibers can be produced by centrifugal spinning, meltblowing, or its spunbonding variation. The fibers can be produced in a microdeni...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide lyocell fibers having pebbled surfaces and variations in cross section and diameter along and between the fibers.SOLUTION: The lyocell fibers can be produced by centrifugal spinning, meltblowing, or its spunbonding variation. The fibers can be produced in a 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 which feel smooth and soft. Alternatively, the fibers can be formed into self-bonded nonwoven fabrics.
