The aim of this study was to examine the use of liposome in the dyeing of wool and mohair fibres with acid dyestuffs. Soybean lecithin and cholesterol were used to form the liposome membrane utilised in the dyebath. Liposome production was performed according to the thin lipid layer method (Bangham Method) using a rotary evaporator. Two different forms of liposome were used for dyeing wool and mohair fibres. In its first form, liposome was utilised as an auxiliary agent, where it was added to a conventional dyebath at the beginning of the process. In its second form, dyes were encapsulated with liposome and then used in dyeing. The effects of these two different forms of liposome were compared with conventional dyeing. Dyeing was carried out at depths of shade of 0.5%, 1.0% and 2.0% using three different concentrations of liposome (0.33%, 0.66% and 1.33%). An analysis of K/S values, fastness to washing, and the alkali solubility of fibres was conducted. The fibre samples dyed in the presence of liposome exhibited very good fastness to light (grade 8). The wash fastness test results of the liposomal‐dyed samples were significantly better (grade 4‐5) than for those samples which were conventionally dyed. In the presence of liposome, the tensile strength of fibres was 20 gf, whereas it was 11 gf without liposomes.

脂质体对马海毛/羊毛混纺染色的影响

这项研究的目的是研究脂质体在用酸性染料对羊毛和马海毛纤维染色中的用途。大豆卵磷脂和胆固醇用于形成染色浴中使用的脂质体膜。使用旋转蒸发仪，根据薄脂质层法（Bangham法）进行脂质体的制造。两种不同形式的脂质体用于染色羊毛和马海毛纤维。在脂质体的第一种形式中，它被用作辅助剂，并在过程开始时将其添加到常规的染浴中。在第二种形式中，染料被脂质体包裹，然后用于染色。将这两种不同形式的脂质体的效果与常规染色进行了比较。使用三种不同浓度的脂质体（0​​.33％，0.）在0.5％，1.0％和2.0％的阴影深度处进行染色。66％和1.33％）。分析进行K / S值，耐洗牢度和纤维的碱溶解度。在脂质体存在下染色的纤维样品表现出非常好的耐光牢度（等级8）。脂质体染色样品的耐洗牢度测试结果（4-5级）明显优于常规染色的样品。在脂质体存在下，纤维的拉伸强度为20 gf，而在没有脂质体的情况下为11 gf。
