椰炭改性涤纶纤维性能分析

Property Analyses of Coconut Charcoal Modified Polyester Fiber

探讨椰炭改性涤纶纤维的可纺性。对椰炭改性涤纶纤维的外貌、组成、强伸性能、吸湿性能、弹性指标等进行了测试。结果表明:椰炭改性涤纶纤维横截面近似为四叶形,纵向有明显的沟槽;红外光谱与普通涤纶纤维、竹炭改性涤纶纤维的红外光谱峰形、峰位一致;干态、湿态断裂强度和初始模量均低于普通涤纶纤维;断裂伸长率与普通涤纶纤维相当;回潮率和质量比电阻高于普通涤纶纤维。认为:应对椰炭改性涤纶纤维进行适当预处理并采取一定工艺技术措施才能保证其顺利生产。

Spinnability of coconut charcoal modified polyester fiber was discussed. Appearance, composition, strength and elongation, hygroscopicity and elastic index of coconut charcoal modified polyester fiber were tested. The re- sult shows that the cross section of coconut charcoal modified polyester fiber is four leaf shape and longitudinal groove. The infrared spectrum peak shape and peak position of coconut charcoal modified polyester fiber are consistent with com- mon polyester fiber and bamboo charcoal modified polyester fiber. Initial modulus, breaking tenacity of coconut charcoal modified polyester fiber in dry state and wet state are lower than that of common polyester fiber. Breaking elongation rate of coconut charcoal modified polyester fiber is same with common polyester fiber, the moisture regain and mass specific resistance are higher than that of common polyester fiber. It is considered that coconut charcoal modified polyester fiber should be pre-treated, certain processing technology measures should be adopted to ensure spinning successfully.
