This invention, the plural multi limb regenerated cellulose fibers where section has the limb of three or more (1 and 2 ) regards the fiber bundle which is included. As for the fiber bundle of this invention, the multi limb cellulose fibers 10%, 20%, especially is desirable at least desirably at least at least 50% being the asymmetric fiber, at least one limb among those differs, the other limb and length, one among those or length of some limbs, the shortest limb (single number or plural) features that 10 times it is longer than length from 2.< Selective figure >Figure 2本発明は、断面が3つ以上の肢を有する複数の多肢再生セルロース繊維(1’、2’)を含む繊維束に関する。本発明の繊維束は、多肢セルロース繊維の少なくとも10%、好ましくは少なくとも20%、特に好ましくは少なくとも50%が非対称の繊維であり、その中の少なくとも1つの肢が、他の肢と長さが異なり、その中の1つまたは幾つかの肢の長さが、最短の肢(単数または複数)の長さよりも2から10倍長いことを特徴とする。【選択図】図2
