采用傅立叶变换红外光谱、扫描电子显微镜、X射线衍射仪和热重分析仪对交联改性制备的吸湿发热聚丙烯腈(PAN)纤维的吸放湿性能进行表征,与普通PAN纤维及进口吸湿发热PAN纤维进行对比。结果表明:交联改性制备的吸湿发热PAN纤维红外光谱出现了较强的羟基峰和羧酸盐的伸缩振动峰,相比普通PAN纤维,表面沟槽加深、粗糙度增加,在100℃内失重率达17.17%,热分解温度提高近70℃,结晶度大幅下降,力学性能降低;交联改性PAN纤维的吸放湿性能较普通PAN纤维大幅度提高,并高于进口吸湿发热PAN纤维,其平衡回潮率约30%,吸湿积分热达155 J/g。 相似文献

通过溶胶–凝胶技术以正硅酸乙酯作为溶胶前驱体对剑麻纤维进行改性,采用傅里叶变换红外光谱(FTIR)、热重(TG)分析、X射线光电子能谱(XPS)分析以及单根纤维拉伸性能测试对改性剑麻纤维进行表征。FTIR和XPS测试结果表明,SiO_2凝胶成功引入剑麻纤维中;TG分析结果表明,经过溶胶–凝胶技术改性后,剑麻纤维的起始热分解温度变化很小,仅提高约0.5℃,但失重率明显降低;拉伸性能测试结果表明,溶胶–凝胶技术改性剑麻纤维的拉伸强度高于未改性的纤维,且剑麻纤维的吸湿率越高,单根纤维的拉伸强度越高,当纤维吸湿率为22.7%时,其拉伸强度较未改性纤维提高了29.21%,较KH550改性纤维提高了7.84%。 相似文献

测试比较了聚酯短纤维、亲水性聚酯短纤维、脱脂棉纤维在不同温度下对气态水的吸湿与放湿性能,分析了纤维中亲水基团对吸湿速率的影响,以及烘干温度对纤维回潮率的影响。结果表明:在105℃条件下,亲水性聚酯短纤维中的水分不能完全脱除;随着烘干温度从105℃上升至125℃,亲水性聚酯短纤维以及脱脂棉纤维继续脱除水分,且水分释放变化率更明显;随着烘干温度从105℃升至125℃,聚酯短纤维的回潮率没有变化,保持在0.40%,而亲水性聚酯短纤维的回潮率从1.33%提高至1.43%;亲水性聚酯短纤维对气态水的吸湿与放湿性能明显强于聚酯短纤维。 相似文献

Most of the commercial flame retardant (FR) polyester fibers are produced using copolymerization with phosphorous FRs. We investigated the fiber properties, dyeing properties, and flame retardancy according to the phosphorous FR type. The physical properties of both the fibers are similar and suitable for textile application. But the dye adsorption rate is much faster in the case of main chain type. This is resulted from higher chain mobility analyzed by glass transition temperature. The main chain type FR polyester fiber adsorbed the dyestuff at lower temperature and reached exhaustion more quickly. And the resistance to chemicals such as acidic and alkaline solutions at high temperature have similar tendency with dye absorption. The migration of dyestuffs and chemicals into the polymer chain has good correlation with chain mobility of the polymers. The main chain type polyester fiber shows better flame retardancy than pendant type polyester, which might be brought about from more rapid degradation into polyphosphoric acid. The main chain type polyester fiber shows better flame retardancy than pendant type polyester. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008 相似文献

Chlorendic anhydride based polyester ( I ,) tetrachlorophthalic anhydride based polyester ( II ), dibromoneopentyl glycol based polyester ( III ,) general purpose polyester ( IV ,) blend of dibromoneopentyl glycol based polyester with general purpose polyester ( V ,) chlorendic anhydride and dibromoneopentyl glycol based polyester ( VI ), and a blend of chlorendic anhydride based polyester and dibromoneopentyl glycol based polyester ( VII ) were prepared and their chemical resistance and moisture absorption studied in various reagents, acid, alkali, and water, at 25 and 65°C. It is found that the polyester ( III ) is the least affected in the presence of the acids. In 20% NaOH, there was a decrease in weight for all polyesters at both the temperatures compared to the control except the polyester ( VII ). Increase in weight of all the polyesters was observed during the absorption of moisture both at 25 and 65°C. The increase was higher at higher temperature. Polyester ( III ) thus shows the least absorption of moisture. 相似文献
