Abstract: The present invention relates to a lyocell fiber, and more specifically to a lyocell fiber, wherein the cross-sectional shape of a monofilament contained in the lyocell fiber is controlled to thus increase the specific surface area of the fiber, thereby exhibiting properties equal or superior to those of conventional lyocell fibers, even when used in a small amount.

Abstract: This invention relates to a method of manufacturing a lyocell material for a cigarette filter, including (S1) spinning a lyocell spinning dope composed of 8 to 13 wt % of a cellulose pulp and 87 to 92 wt % of an N-methylmorpholine-N-oxide (NMMO) aqueous solution; (S2) coagulating the lyocell spinning dope spun in (S1), thus obtaining a lyocell multifilament; (S3) water-washing the lyocell multifilament obtained in (S2); (S4) oiling the lyocell multifilament water-washed in (S3); and (S5) applying steam and pressure to the lyocell multifilament obtained in (S4), thus obtaining a crimped tow having 30 to 40 crimps per inch.
