SPINNERET FOR EXTRUDING SELF-CRIMPING HOLLOW FIBERS, SELF-CRIMPING HOLLOW FIBERS, AND METHOD FOR PRODUCING SELF-CRIMPING HOLLOW FIBERS |
| 摘要 |
The invention relates to a spinneret for extruding self-crimping hollow fibers including at least one capillary. The at least one capillary has at least one segmented opening, which has at least two opening segments spaced apart from each other in the cross-section. A first opening segment of the at least two opening segments has a first opening-segment width and a second opening segment of the at least two opening segments has a second opening-segment width. The second opening-segment width is wider than the first opening-segment width. |
