| 摘 要： | 采用臭氧对聚酯非织造布进行处理。经红外光谱(FT-IR)与表面过氧化物浓度分析表明,经臭氧处理后,聚酯非织造布表面引入了含氧极性基团(羰基、过氧化物)。随着臭氧处理时间的延长,羰基含量增加,过氧化物浓度增大。差示扫描量热(DSC)分析表明,所用的聚酯非织造布有两个熔融峰,应为聚对苯二甲酸丁二醇酯与聚对苯二甲酸乙二醇酯纤维混合物。经过臭氧处理以后,聚酯非织造布的两个熔融峰基本不变。当臭氧处理10min时,聚酯非织造布的结晶度增加,随着臭氧处理时间的延长,结晶度有所下降。经过臭氧处理后,聚酯非织造布的断裂强力和断裂伸长率下降。

| Abstract: | Polyester(PES)nonwoven was treated with ozone.Fourier transform infrared spectrum(FT-IR)and surface peroxide concentration analysis show that through ozone treatment,some oxygen-containing groups(carbonyl groups and peroxide)were introduced onto the surface of PES nonwoven.With prolonging ozone treating time,both the content of carbonyl groups and the concentration of peroxide increase.Two melt peaks appear in DSC heating thermogram of PES nonwoven.This indicats that the PES nonwoven used in our experiment ... |
