功能性纺织品应用中芳香族三聚氰胺微胶囊的粒径与释放特性之间的关系

研究了功能性纺织品中芳香族三聚氰胺树脂微胶囊的粒径与释放特性的关系。首先，微胶囊的特征在于基于其傅里叶变换红外光谱，包封率，粒度分布，光学图像，和扫描电子显微镜图像。利用图像分析对微胶囊的浸渍性能进行了初步评价。采用固相微萃取-气相色谱-质谱联用技术半定量分析了复合材料的浸渍效率和破胶释放特性。结果表明，当微胶囊粒径与纤维直径相近（25-30 μm）时，微胶囊的浸渍效率和破膜释放强度最高。最后，使用称重计算方法评价微胶囊在2400 h内的持续释放，并使用Peppas模型研究趋势。结果表明，微胶囊的释放速率随时间缓慢而持续下降，随着微胶囊粒径的减小，释放速率显著增加。因此，可以得出结论，大微胶囊比小微胶囊表现出更好的密封性，而小微胶囊表现出更快的持续释放速率。
The relation between the particle size and release characteristics of aromatic microcapsules with a melamine resin shell in functional textile applications have been investigated. Firstly, the microcapsules are characterized based on their Fourier transform infrared spectra, encapsulation efficiencies, particle size distributions, optical images, and scanning electron microscopy images. The impregnation performances of the microcapsules have been initially evaluated using image analysis. Subsequently, the impregnation efficiency and broken release characteristics are semi-quantitatively analyzed using solid-phase microextraction-gas chromatography-mass spectrometry. The analysis results show that the highest impregnation efficiency and broken release intensity could be observed when the microcapsule size was similar to the fiber diameter (25–30 μm). Eventually, the sustained release of the microcapsules over a period of 2400 h was evaluated using the weighing calculation method, and the trends were studied using the Peppas model. It was found that the microcapsule release rate slowly and continuously decreased with time, and the release rates significantly increased with the decrease in microcapsule particle size. Thus, it could be concluded that the large microcapsules exhibited better leak tightness than the small microcapsules, whereas the small microcapsules exhibited faster sustained release rates.
