新型抗静电聚酯纤维的制备及其结构性能

Preparation,structure and properties of new antistatic polyester fiber

以三氧化二锑、醋酸钴和醋酸钠为催化剂,采用原位聚合方法制备改性共聚酯/无机导电粉体复合物,经过熔融纺丝得到纤维。采用SEM、DSC、XRD、TG等方法对聚酯切片及纤维的结构和性能进行表征。结果表明:经过表面处理后的无机导电粉体在改性共聚酯(MCPET)基体中分散均匀;无机导电粉体的加入提高了MCPET的结晶速度和结晶度。加入质量分数为1%的导电粉体的纤维质量比电阻为2.1×108Ω.g/cm2,具有优异的抗静电效果。

Modified copolyester（MCPET）/inorganic conductive nanoparticle composites were prepared by in-situ polymerization using antimony trioxide,cobaltous acetate and sodium acetate as the catalyst,and the corresponding fibers were acquired by melt spinning.The structure and properties of the polyester pellets and fibers were characterized by SEM,DSC,XRD and TG.It was found that after surface modification the conductive nanoparticles were well dispersed in the MCPET matrix.The crystallization rate and crystallinity of the MCPET were enhanced with the addition of the inorganic conductive nanocomposites.When 1% of the conductive nanopaticles were added,the melt spun fiber had a specific resistance of 2.1×108 Ω·g/cm2 and exhibited excellent anti-static property.
