Trilobal, swirl-shaped and T-shaped SiC fibers were prepared from precursor polymer.
通过先驱体转化法，制备出三叶形、三折叶形和T形截面碳化硅纤维。
Comparing with the routine PET, the trilobal PET has lower strength and modulus, while its elongation is larger.
与常规圆形丝相比，高伸长异形丝的强度和模量低而断裂伸长率高。
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著作用。
The results were showed that the profile degree of trilobal PCS fibers decreased with a rise in spinning temperature, spinning pressure and rotation velocity.
结果表明：纤维异形度随纺丝温度、纺丝压力、收丝速度的升高而降低。
