摘要: 利用水热合成技术,以钛酸四丁酯为原料,在去离子水溶液中直接对锦纶织物纤维表面包覆纳米二氧化钛薄膜,使用活性艳蓝染料R-X对锦纶织物进行染色,借助扫描电镜、X射线衍射、红外光谱、差示扫描量热和热重测试手段对锦纶纤维改性前、后的表面形貌、结构和热学性能进行了表征,测定了织物反射光谱、拉伸、吸水和染色性能。结果表明锦纶织物经过钛酸四丁酯水热改性之后,纤维表面包覆纳米二氧化钛为锐钛矿型,由平均粒径10 nm左右的球形晶粒组成,且通过物理吸附方式附着在纤维表面;纤维热起始分解温度有所下降,出现较为明显的放热反应;紫外线吸收能力明显改善;由于织物尺寸发生收缩,断裂强力和断裂伸长率均有所增加;吸水性能变化不大;染色织物K/S值有所减小,但刷洗之后K/S值反而增大,耐摩擦和耐日晒性能较好。

Abstract: Nanometer-sized titanium doixide films prepared by hydrothermal precipitation method were first immobilized on the surface of polyamide fibre using tetrabutyl titanate, and then dyed with Remazol Brillant Blue R-X. Scanning electron microscope (SEM), X-ray diffraction (XRD), infrared spectroscopy (IR), differential scanning calorimetry (DSC) and thermal gravimetric (TG) analyses were used to characterize the morphology, crystalline phase, chemical structure and thermal stability of titanium doixide coated fibre. The properties of reflectance spectrum, tensile, water absorption, K/S value and color fastness for polyamide fabric were measured. It was observed that when polyamide fabric was treated with tetrabutyl titanate aqueous solution at 120 ℃ for 5 h, pure anatase nanocrystaline titanium doixide particles of average size 10 nm were synthesized, and adhered onto fibre surface by means of physical mode. As compared with the untreated fabric, the onset decomposition temperature of TiO2-coated fabric decreased. The capability of against ultraviolet radiation was improved. The breaking load and tensile strain in warp and weft directions increased to some extent due to the shrinkage of fabric size. The water absorption changed a little. The color yield (K/S value) decreased slightly, but then increased after being washed with water. The color fastnesses to rubbing did not change. The K/S values of TiO2-coated fabric irradiated by ultraviolet ray at different time decreased slowly compared with that of untreated one.
