摘要:

针对棉织物抗紫外线及抗皱性较差的缺点,用芦荟蒽醌化合物和柠檬酸、酒石酸对棉织物进行后整理,通过多元羧酸的桥联作用,使蒽醌提取物与棉纤维大分子发生较为牢固的化学结合,使棉织物同时获得耐久的抗皱抗紫外性能。通过扫描电子显微镜、红外光谱图、x射线衍射测试,证实多元羧酸与棉纤维大分子按环酐机制发生了酯化反应,芦荟蒽醌通过多元羧酸的桥联作用以化学键的形式固定在棉纤维上。对整理后织物的紫外线透过率、断裂强力、白度、折皱回复角等性能进行测试,结果表明,棉织物的抗皱性能和抗紫外性能明显提高。

Abstract:

Aiming at the shortcomings of cotton fabric such as poor in UV and wrinkle resistance, aloe anthraquinones and citric acid, tartaric acids were used to finish it so that fast chemical bonding between aloe extraction and macromolecules of cotton fibers ware achieved through the bridging function of Polycarboxylic acids. Meanwhile, cotton fabrics have been rendered with perminent UV and wrinkle resistance. Scanning electron microscope, infrared spectrogram and X-ray diffraction were used to characterize the treated fabric. It was confirmed that esterication reaction occurred between polycarboxylic acids and macromolecule of cotton fiber according to ring-anhydride mechamism and aloe anthraquinones were fixed on the cottn fiber as chemical bond through the bridging function of Polycarboxylic acids. The ultraviolet transmissibility, breaking strength, whiteness, crease recovery angle of the treated fabrics were examined. The results indicated that the wrinkle-resistance and anti-ultraviolet properties of the fabric improved remarkably.
