ABSTRACT
Parameters affecting extraction of natural colorants from five binary mixtures of floral parts of Callistemon citrinus and Tagetes erecta L., like ratio of each flower in the binary mixture of powdered floral parts, amount of powdered binary mixture to liquor ratio and extraction time, were optimized for dyeing of cotton fabric. Optimum dyeing was obtained at 60°C with 70 g/L exhausting agent (Na2SO4), material to liquor ratio of 1:50 along with dyeing time of 100 min. The dyed fabric revealed good anti-bacterial activity and excellent ultraviolet protection factor (UPF).
摘要
参数影响天然色素提取从Callistemon citrinus和Tageteserecta L.的五个二元混合物的花的组成部分,如在粉花各部分的混合物每花比,以白酒类比和提取时间对粉末混合量,对棉织物的染色优化。在60°C 70 g/L排气剂获得最佳染色(Na2SO4),材料白酒类比1:50随着染色时间100分钟。染色织物具有良好的抗菌活性和优良的紫外线防护系数(UPF)。
