Eco-friendly antibacterial and biocompatible coatings by applying cinnamon essential oil and propolis based emulsions on cotton textiles

ABSTRACT

The aim of this paper was to obtain bioactive textiles suitable for skin applications using a polymeric bioactive system based on xanthan-propolis-cinnamon essential oil. Oil-in-water emulsion was immobilized by padding method on two weave fabrics made from 100% cotton yarns (V₁) and 100% cotton yarns in warp direction blended with 80% cotton/20% Smartcel^TM Sensitive in weft direction (V₂). The functionalized textiles were characterized regarding their physical-mechanical characteristics, hydrophilicity, and antibacterial activity. Cell viability, membrane integrity, and inflammation status of the functionalized fabrics were evaluated on HaCaT human keratinocytes. Mass of both textile fabrics increased depending on the amount of immobilized emulsion that remained after the functionalization process. Slightly lower values of hydrophilicity were obtained for both fabrics that showed a wettability of 1.30 seconds. Water vapor permeability and air permeability had lower values compared to control. An antibacterial activitiy was observed for both samples against Escherichia coli and Staphylococcus aureus. The organization of filamentous actin in cells cultured in the presence of bioactive textiles was kept within the normal limits. V₂ sample displayed good biocompatibility without skin irritation, recommending for further dressings and clothes with medical applications or daily usage.

摘要

本论文的目的是利用基于黄原胶-蜂胶-肉桂精油的聚合物生物活性体系, 获得适合皮肤应用的生物活性纺织品. 采用填充法将水包油乳液固定在由100%棉纱 (V1) 和100%棉纱 (经向) 与80%棉/20%SmartcelTM (纬向敏感) 混纺的两种织物上. 对功能化纺织品的物理机械特性, 亲水性和抗菌活性进行了表征. 在HaCaT人角质形成细胞上评估功能化织物的细胞活力, 膜完整性和炎症状态. 两种织物的质量都随着功能化过程后残留的固定化乳液的量而增加. 两种织物的亲水性值略低, 润湿性为1.30秒. 与对照组相比, 水蒸气渗透率和空气渗透率的值较低. 两种样品对大肠杆菌和金黄色葡萄球菌均有抗菌活性. 在含有生物活性纺织品的培养细胞中, 丝状肌动蛋白的组织保持在正常范围内. V2样品显示出良好的生物相容性, 无皮肤刺激, 建议用于医疗应用或日常使用的进一步敷料和衣服.
