| abstract |
Multi-layer hollow fiber winding body, in which at least some of the hollow threads are helical and / or some of the hollow threads are spiral, the hollow threads are arranged within each hollow thread layer at a mutual distance, the hollow threads of adjacent successive hollow thread layers cross, the hollow threads in the form of at least two superimposed ones and then spirally wound hollow thread mats are arranged, the hollow threads are held within each hollow thread mat by a plurality of inserted transverse threads or the like, the mutual distance of the transverse threads or the like being greater within each hollow thread mat than the mutual distance of the hollow threads, and none of the hollow threads having a deflection point, according to the invention the ratio of the mutual spacing of adjacent transverse threads within each hollow fiber mat to the mutual spacing of adjacent hollow threads within each hollow thread mat is in the range from 2 to 40. |
