POD纤维在防电弧混纺织物中的应用

Application of POD fiber in anti-arc blended fabrics

为优化防电弧面料设计,基于防电弧面料Protera的混纺原料和混纺比,纺制了不同混纺比的阻燃腈氯纶/芳纶1313/POD(聚芳噁二唑纤维)/对位芳纶混纺织物,并对其强伸性、耐磨性、透气性、透湿性、阻燃、热稳定、热膨胀和热防护性能进行测试,探讨了POD纤维对其舒适性和防护性能的影响。研究结果表明:与芳纶1313相比,在稳定织物强力,增加耐磨性的同时,POD纤维改善了防电弧面料的舒适性和防护性能,其中,织物耐磨性是芳纶1313的两倍,透湿性增加了35%,电荷半衰期减少57%,热膨胀率增加了20%,热防护性能值(TPP)增加9. 2%,但是损毁长度减少22%,热收缩率降低12%。

In order to optimize the designs of anti-arc fabrics,according to blending materials and blending ratio of anti-arc fabric Protera,the blended fabrics of Vinyon N/aramid fiber 1313/POD(polyaromatic oxadiazole fiber)/para-aramid with different blending ratio were spun,and the extensibility,wear resistance,air permeability,moisture permeability,flame retarding,thermal stability,thermal expansion and thermal protection performance were tested.The effects of POD fiber on comfort properties and protection properties were also explored.The test results showed that compared with aramid fiber 1313,POD fiber improved the comfort and protection properties of anti-arc fabrics while stabilizing fabric strength and increasing wear resistance.In addition,the wear resistance was twice than that of aramid fiber 1313,and moisture permeability increased by 35%;charge half-life decreased by 57%;thermal expansion rate and TPP value increased by 20%,and 9.2%respectively,but damage length and heat shrinkage reduced by 22%and 12%respectively.
