Effects of Phosphatidylcholine/Cholesterol Liposome-Assisted Dyeing on Woolen Fabric Properties

ABSTRACT

In this study, the effect of liposome, which was constituted from soya lecithin and cholesterol, was investigated in wool dyeing. Different types of liposomes were used for dyeing wool fabrics. In the first type, liposomes were utilized as an auxiliary. Liposome was added to conventional dyebath at the beginning of the process for the liposome trials. In the second type, dyes were encapsulated with liposome and then used in wool dyeing. The effects of these two different types of liposomes were compared in conventional dyeing. The dyed woolen fabrics were characterized by fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), solubility in alkali, dye exhaustion aspects and breaking strength tests. Three kinds of dyeing agents – 1:2 metal complex, acid and reactive dyes, were chosen in this current study. The color strength values, fastness to washing, perspiration and light were also determined according to the different color strengths. Fastness results were evaluated according to ANOVA statistical analysis. The dyed fabrics in the presence of liposomes exhibited very good fastness to light (grade 6, 7) and the perspiration, rubbing and washing fastness test results of the samples were much better (grade 4–5) for the liposomal dyeing than for the other samples. In the presence of liposomes, the breaking load of the fabric pecimens was measured as 25 N, whereas without liposomes, it was 19 N. Exhaustion aspects involving dye adsorption and bonding on wool samples were also investigated. The controlled exhaustion of dye on wool samples was dependent on whether the dyeing included liposomes.

摘要

本文研究了大豆卵磷脂和胆固醇组成的脂质体在羊毛染色中的作用. 不同类型的脂质体用于羊毛织物的染色. 在第一种类型中，脂质体被用作辅助剂. 在脂质体试验开始的过程中，Liposome加入到传统的染色浴中. 第二种是用脂质体包裹染料，用于羊毛染色. 比较了两种不同类型脂质体在常规染色中的效果. 用傅立叶变换红外光谱（FTIR）、扫描电镜（SEM）、碱溶性、染料耗竭性和断裂强力试验对染色羊毛织物进行了表征. 本研究选择了三种染色剂——1:2金属络合物、酸性染料和活性染料. 根据不同的色强，测定了织物的色强值、耐洗牢度、耐汗渍性和耐光性. 根据ANOVA统计分析评价牢度结果. 在脂质体存在下，染色织物具有很好的耐光牢度 (6, 7级)，样品的汗液、摩擦和洗涤牢度测试结果比其它样品要好得多 (4-5). 在脂质体的存在下，测定了织物的断裂载荷为25 N，而没有脂质体时，其断裂强度为19 N. 还研究了羊毛上的染料吸附和粘合. 染料对羊毛样品的控制消耗取决于染色是否含有脂质体.
