摘要
利用电子束辐照接枝的方法将丙烯酸(Acrylic acid, AA)单体接枝到涤纶织物上来改善其亲水性。通过改变吸收剂量、接枝单体浓度、阻聚剂浓度、预辐照的吸收剂量以及前处理氢氧化钠浓度等影响因素来获得具有不同接枝率的改性涤纶织物。优化的反应条件:吸收剂量为195 kGy、AA浓度为50%、阻聚剂(FeSO,4,·7H,2,O)浓度为0.8%、预辐照的吸收剂量为43 kGy、前处理NaOH浓度为15 g/L。傅里叶红外光谱证明AA已接枝成功;扫描电子显微镜分析表明改性涤纶织物的表面具有覆盖物,且随着接枝率的增大,其覆盖物明显增多;回潮率测试结果表明,改性涤纶的回潮率随接枝率的增加而逐渐增大,当接枝率达到最大值27.84%时,改性涤纶的回潮率可达3.51%。涤纶织物经30次洗涤后减重率仅1%左右,说明接枝牢度优异。
Abstract
Acrylic acid (AA) monomers were grafted onto polyester fabric by electron beam irradiation to improve the hydrophilic properties. The optimized reaction conditions were as follows: absorbed dose of 195 kGy, AA concentration of 50%, inhibitor concentration of 0.8%, absorbed dose of pre-irradiation process of 43 kGy, and sodium hydroxide concentration of 15 g/L. The Fourier transform infrared spectrometer spectra showed that AA was grafted onto polyester fabric successfully. The (SEM) showed that the surface of the modified polyester fabric was covered with the film of the grafted polymer. Further, the area of film increased with the grafting rate significantly. The moisture regain of polymer fiber increased with the grafting rate according to the test of moisture regain. The moisture regain of grafted fabric reaches 3.51% when the maximum grafting rate is 27.84%. The fabric still has good hydrophilicity after 30 washing cycles with only 1% of weight loss.
