在这项研究中,目的分析脂质体对聚丙烯腈织物染色的影响。为此,首先进行脂质体合成,然后通过傅里叶变换红外光谱分析确认脂质体的生产。此外,进行ζ电位测量以查看是否形成稳定的结构。然后,用脂质体包封选定的碱性染料,并研究了在聚丙烯腈织物染色中使用这些胶囊替代缓凝剂的可能性。根据获得的结果,可以说,合成脂质体的1%溶液产生了更稳定的悬浮液,多分散指数为0.472,平均粒径为165.2nm。另一方面,据透露,如果在染色中使用1%的脂质体,在聚丙烯腈织物的染色中可以达到一种缓凝效果。此外,可以说,色彩效率的降低,也就是说,产量的损失,与缓凝剂相比,在染色结束时使用脂质体引起的较低。这也是一个非常重要的问题,因为良好的缓凝剂有望减缓染料的吸收,但不要在染色结束时减少染料的摄入量。无辅助染色的染色水平度(%)分别为96.1、97.4和97.1。含1%阳离子缓凝剂和1%脂质体,分别。除此之外,在染色牢度方面没有观察到显著差异。
In this study, it was aimed to analyze the effects of liposomes on the dyeing of polyacrylonitrile fabrics. For this purpose, firstly liposome synthesis was carried out, and then liposome production was confirmed by Fourier transform infrared spectroscopy analysis. Additionally, zeta potential measurements were carried out to see whether stable structures were formed. Then, a selected basic
dye was encapsulated with a liposome and the possibilities of using these capsules as alternative to retarders in the dyeing of polyacrylonitrile fabrics were examined. According to results obtained, it can be said that the 1% solution of synthesized liposomes creates a more stable suspension with a polydispersity index of 0.472 and the average particle size of 165.2 nm. On the other hand, it has been revealed that if 1% liposome is used in dyeing, a kind of retarder effect can be achieved in the dyeing of polyacrylonitrile fabrics. Moreover, it can be said that the decrease in color efficiency, that is, the loss of yield, caused by the use of liposome at the end of dyeing is lower compared to the retarder. This is also a very important issue, because a good retarder is expected to slow down the
dye uptake, but not reduce the
dye intake too much at the end of the dyeing. Dyeing levelness (%) was found to be 96.1, 97.4, and 97.1 for dyeings without auxiliary, with 1% cationic retarder and with 1% liposome, respectively. Beyond this, no significant difference was observed in terms of fastness of dyeing.
