LYOCELL FIBER

摘要

This invention relates to a lyocell fiber and, more specifically, to a lyocell fiber exhibiting the same or improved physical properties even if used in a lesser amount, compared to a conventional lyocell fiber, by controlling the shape of the section of a monofilament included in the lyocell fiber to increase the specific surface area of the fiber.

主权项

1. A lyocell fiber comprising:
a lyocell multifilament manufactured by spinning a lyocell spinning dope including a cellulose pulp and an N-methylmorpholine-N-oxide (NMMO) aqueous solution, wherein the multifilament includes a monofilament having a multi-lobal section, the multi-lobal section includes a plurality of projections, and the plurality of projections comes into contact with a first virtual circle and a second virtual circle, included in the first virtual circle, is integrally formed with the second virtual circle, serving as a core, and comes into contact with the first virtual circle at ends thereof.
