    CPC classification number: D01F2/00

    Abstract: The present invention relates to a fiber of the Lyocell type which has a titer of from 0.8 dtex to 3.3 dtex and is characterized by the following relationships: Höller factor F2≧1, preferably ≧2 Höller factor F1≧−0.6 Höller factor F2≦6 and Höller factor F2 minus 4.5*Höller factor F1≧1, preferably ≧3. The fiber according to the invention displays a specific combination of properties with regard to the Höller factors, the flexibility and the abrasion resistance within a planar assembly. Hence, the fiber shows a behavior more similar to viscose and can be processed in the textile chain according to viscose standard methods.

    Abstract: The present invention relates to the use of a multilobal cellulosic staple fiber as a filling fiber. Furthermore, the invention relates to a cellulosic staple fiber which is characterized in thatthe cross-section of the fiber has three or more lobesthe titer of the fiber is 1.0 to 30 dtex, preferably more than 3.0 dtex, especially more than 5.0 dtex, preferably 5.6 to 10 dtex, especially preferred more than 6.0 dtex, especially 6.3 to 10 dtexthe wet modulus of the fiber fulfils the following formula: Wet modulus (cN/tex)≧0.5*√T wherein T is the titer of the fiber in dtex the breaking strength of the fiber in the conditioned state fulfils the following formula: Breaking Strength (cN/tex)≧+2*T wherein T is the titer of the fiber in dtex.

    Abstract translation: 本发明涉及多叶纤维素短纤维作为填充纤维的用途。 此外，本发明涉及一种纤维素短纤维，其特征在于，纤维的横截面具有三个以上的叶片，纤维的滴度为1.0〜30分特，优选为3.0dtex以上，特别是5.0dtex以上， 优选为5.6〜10分特，特别优选6.0dtex以上，特别是6.3〜10分特，纤维的湿模量满足下式：湿模量（cN / tex）> = 0.5×√T其中T为纤维滴定度 在dtex中，纤维在调理状态下的断裂强度满足下列公式：断裂强度（cN / tex）> = + 2 * T其中T是以dtex为单位的纤维滴定度。

    IPC: D01F2/00

    Abstract: The present invention relates to a fiber of the Lyocell type which has a titer of from 0.8 dtex to 3.3 dtex and is characterized by the following relationships: Höller factor F2≥1, preferably ≥2 Höller factor F1≥−0.6 Höller factor F2≤6 and Höller factor F2 minus 4.5*Höller factor F1≥1, preferably ≥3. The fiber according to the invention displays a specific combination of properties with regard to the Höller factors, the flexibility and the abrasion resistance within a planar assembly. Hence, the fiber shows a behavior more similar to viscose and can be processed in the textile chain according to viscose standard methods.
