Abstract (en)
[origin: WO2011116848A2] A multi-component fiber, comprising a first component and a second component, which together form a fiber body (11), the first component being made of a first fiber raw material (1) and the second component being made of a second fiber raw material (3), is characterized by production by means of a rotational spinning method with regard to the aim of creating a multi-component fiber in which heat-sensitive fiber raw materials are processed without damage. A method, in which a first fiber raw material (1) is poured into a first container (2), a second fiber raw material (3) is poured into a second container (4), both containers (2, 4) are rotated, the first fiber raw material (1) is discharged from the first container (2), the second fiber raw material (3) is discharged from the second container (4), the fiber raw materials (1, 3) are combined after leaving the containers (2, 4), the containers (2, 4) are rotated about the same axis (A), the first fiber raw material (1) is discharged from the first container (2) through a first channel nozzle (5, 9a), and the second fiber raw material (3) is discharged from the second container (4) through a second channel nozzle (6, 10a), achieves the aforementioned aim.
