It was found that fibers of circular cross section produce greater cohesion in webs and slivers than do trilobal fibers.

圆形横截面纤维在棉网和棉条中，比三叶形横截面纤维能产生较大的粘着作用。

Trilobal polycarbosilane(PCS) fibers were prepared by melt spinning PCS precursor through Y-shaped spinnerret.

以聚碳烷（PCS）为原料，经不熔化和烧成制得三叶型碳化纤维。
