Because the fiber is of chemical inertion, low surface energy, lack of polar groups, and highly symmetric methylene structure, the fiber has a high degree of crystallinity and orientation.
这是由于纤维在化学上不活泼,表面能低,表面缺乏极性基团,且是高度对称的亚甲基结构,使得纤维具有很高的结晶度和取向度。
It is found that plasma treatment can impart the acrylic fiber increased surface roughness and the improved hygroscopicity by the introduction of polar functions containing oxygen and nitrogen.
结果表明,腈纶纤维经等离子体处理后表面粗糙度增加,大量的含氧和含氮极性基团被引入到纤维表面,使纤维表面吸湿性能得到显著改善。
The surface of the treated fibre contains more hydrophilic groups of oxygen and nitrogen. The increase of the number of polar surface groups accounts for the increase of fiber cohesion.
等离子体处理兔毛引起其表面性能变化的原因是由于表面极性基团增加的缘故。
