Two kinds of T-ZnOw whiskers with different dimensions(big and small one) are introduced into PA6 composites.Our results show that for the big whisker and the small whisker both,the addition of T-ZnOw induces the mechanical property improvement of T-ZnOw/PA6 composites.Especially,...展开更多

Influences of cross blowing, spinning speed, PA6 and PET component ratio, drawing condition etc. on the mechanical properties, heat shrinkage,orientation and crystallization of the fiber were investigated. Also the rules among these influencing parameters were obtained. The splitting property of the fiber and its influence on the textile processing are discussed, which offers a base for the production of PA6/PET bicomponent fiber using splitting technology.展开更多
