In this study, the objective was to ensure anti‐bacterial properties for originally coloured wools with naturally sourced garlic stem extracts. In addition, zinc chloride‐based treatment was also carried out. The aim was to retain the original colours of the wool fibres during these treatments. The effects of both treatments were evaluated in terms of colour changes in the wool fibres. It was found that the colour changes caused by the treatments were high in white/ecru fibres but more limited in black fibres. The colour differences between the treated and untreated black fibres were near 1; they were also quite high in white/ecru fibres. The anti‐bacterial properties of the treated wool fibres against two bacteria species, one gram‐negative and one gram‐positive, were also investigated. It was observed that zinc chloride‐based treatment ensured significant anti‐bacterial efficiencies against the bacteria tested and 99.9% bacterial reduction in all cases. However, the anti‐bacterial effects of garlic stem extract‐based treated wool fibres were limited. It was observed that treatment of wool fibres with garlic stem extracts resulted in no anti‐bacterial efficiency against Escherichia coli but did provide some anti‐bacterial capability against Staphylococcus aureus. The highest bacterial reduction of S. aureus was 80.7% in originally brown‐coloured wool fibre.

用大蒜茎提取物和氯化锌处理原色羊毛，以确保抗菌性能且颜色变化有限

在这项研究中，目的是确保使用天然来源的大蒜茎提取物对原始颜色的羊毛具有抗菌性能。此外，还进行了氯化锌基处理。目的是在这些处理过程中保留羊毛纤维的原始颜色。根据羊毛纤维的颜色变化评估了两种处理的效果。发现由处理引起的颜色变化在白色/淡蓝色纤维中较高，而在黑色纤维中则更为有限。处理过的和未处理过的黑色纤维之间的色差接近1。它们的白色/淡绿色纤维含量也很高。还研究了处理过的羊毛纤维对两种细菌（一种革兰氏阴性和一种革兰氏阳性）的抗菌性能。观察到，在所有情况下，基于氯化锌的处理均确保对测试细菌具有显着的抗菌效率，并减少了99.9％的细菌。但是，基于大蒜茎提取物处理的羊毛纤维的抗菌作用有限。据观察，用大蒜茎提取物处理羊毛纤维不会产生抗菌功效。大肠杆菌，但确实提供了一些针对金黄色葡萄球菌的抗菌能力。在最初的棕色羊毛纤维中，金黄色葡萄球菌的最高细菌减少率为80.7％。
