ABSTRACT
The aim of the present study was to develop eco-friendly antibacterial finish from Ghamra and Apamarga leaf extract and its application on textile. Aqueous and methanol extracts from Ghamra and Apamarga leaf had been applied to cotton fabric using pad dry cure method. Antibacterial efficacy of finished fabric samples were tested against Bacillus cereus and Pseudomonas aeruginosa and counted quantitatively by AATCC-100 test method. For testing the efficacy of finish, the samples were inoculated with selected bacterium and further tested to check their bacterial resistance by calculating the percentage reduction in bacterial count. The observations were taken after 24, 48, 72, and 96 hours of inoculation. The results revealed that samples finished with Ghamra and Apamarga leaf extracts showed 100% reduction after 24 hours of inoculation against both bacterial strains, respectively. After 48 hours, it gradually decreased and after 96 hours it decreased to 94.5% and 94.1% against Bacillus cereus and 94.2% and 94% against Pseudomonas aeruginosa in treated samples, respectively. The results also indicated that samples finished with Ghamra and Apamarga leaf extracts provided excellent ultraviolet protection, i.e. 44.51 and 45.37 as exhibited by higher UPF values. The surface morphological studies using SEM showed some fibrillation.
摘要
本研究的目的是开发以加姆拉和阿玛玛叶提取物为原料的环保型抗菌整理剂及其在纺织品上的应用. 采用垫干固化法将加姆拉叶和阿达玛加叶的水提取物和甲醇提取物应用于棉织物上. 对成品织物样品进行了对蜡样芽孢杆菌和铜绿假单胞菌的抗菌效果测试，并用AACC-100测试方法进行了定量计数. 为了测试面漆的功效，用选定的细菌接种样品，并通过计算细菌计数的减少百分比来进一步测试其细菌耐药性. 在接种24、48、72和96小时后进行观察。结果显示，用Ghamra和Apamarga叶提取物完成的样品在对这两种菌株接种24小时后分别显示出100%的减少. 48小时后，它逐渐降低，96小时后，在处理的样品中，它对蜡样芽孢杆菌和铜绿假单胞菌分别降低到94.5%和94.1%和94.2%和94%. 结果还表明，用Ghamra和Apamarga叶提取物完成的样品提供了极好的紫外线保护，即44.51和45.37，如较高的UPF值所示. 使用SEM进行的表面形态研究显示出一些纤化.

Highlights
Ghamra and Apamarga are unwanted weed plants. They have no importance rather pose problems while planting. Hence, synthesis of antibacterial agent from such waste weed plants is a novel idea.
The raw material used for imparting antibacterial finish being purely natural, it is eco-friendly having social, economic and environmental benefit.
The antibacterial renewable treatment on cotton fabric not only provided resistance against the growth of bacteria (Bacillus cereus and Pseudomonas aeruginosa) but also enhanced the UPF value. This will help in manufacturing of antibacterial, ultraviolet protection and easy care textiles required for medical and field activities.
