摘要
通过冻胶纺丝的方法制得了屏蔽剂BaSO4含量达70%的屏蔽X-射线纤维,讨论了BaSO4含量对共混纤维的力学性能、结晶性能的影响。研究表明,随屏蔽剂BaSO4含量的增加,共混纤维的各项力学性能指标均变差,纤维的结晶度、结晶温度均随之发生变化。
BaSO4/poly （vinyl alcohol）（PVA） blend fibers were prepared by gel spinning process, and the maximum BaSO4 content was up to 70 %. The influences of BaSO4 content on the mechanical properties, thermal property and crystallization behavior were investigated. The mechanical properties of the fibers were decreased with the increase of the BaSO4 content. The crystal property was also varied with different BaSO4/PVA ratios.
