This paper presents the application of conventional potassium aluminium sulphate wool mordanting and a biochemical method with silver nitrate (as antimicrobial agent and mordant)_, alone and in combination with oxygen plasma, as part of comprehensive research into pretreatment processes for wool dyeing with natural extract from pomegranate peel (Punica granatum L.). Pretreatment with oxygen plasma significantly improved the hydrophilicity and tensile strength of all tested samples and showed that oxygen plasma can improve K/S, washing fastness, and even replace certain mordants in wool dyeing with natural pomegranate dye. All dyed samples exhibited good antibacterial activity against Staphylococcus aureus, which can be contributed to the phenol content in pomegranate dye. Only after 28 days of intensive ageing in natural weathering conditions did K/S and antibacterial activity against Klebsiella pneumoniae slightly decrease in dyed samples pretreated with oxygen plasma.

氧等离子体预处理可改善用石榴皮天然提取物染色的羊毛织物的染色和抗菌性能

本文呈现常规钾硫酸铝羊毛媒染中的应用，并与硝酸银的生化方法（如抗微生物剂和媒染剂）_，单独和与氧等离子体组合，全面研究对羊毛染色与天然提取物的预处理流程的一部分石榴皮（Punica granatum L. ）。氧等离子体预处理显着改善了所有测试样品的亲水性和拉伸强度，并表明氧等离子体可以改善K / S，耐洗牢度，甚至可以用天然石榴染料代替羊毛染色中的某些媒染剂。所有染色样品对金黄色葡萄球菌均表现出良好的抗菌活性，这可能有助于石榴染料中的苯酚含量。在自然风化条件下经过28天的强烈老化后，在经过氧等离子体预处理的染色样品中，K / S和对肺炎克雷伯菌的抗菌活性才略有下降。
