摘要： This invention relates to a lyocell material for a tobacco filter and a method of manufacturing the same, and more particularly to a lyocell fiber having a modified cross-section for a tobacco filter, wherein the cross-sectional shape of a monofilament contained in a lyocell fiber is controlled to increase the external surface area of the fiber, after which then crimps are formed, thereby exhibiting properties equal or superior to those of conventional lyocell materials, even when used in a small amount.
