trilobal

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

以聚碳烷（PCS）为原料，经不熔和烧成制得三叶型碳维。

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

圆形横截面维在网和条中，比三叶形横截面维能大的粘着作用。
