6种金属盐对茶黄素染色棉布效果的影响研究
|
摘要
以三氯化铁、硝酸铝、四氯化钛、氯化锂、氯化镍、氯化钴等6种金属盐作为媒染剂,研究茶黄素在棉织布上的媒染性能,通过染色棉布的色深K/S值、褪色牢度及其力学性能变化,确定媒染剂浓度、染色时间、染色温度和染色pH等优化工艺条件。结果表明:除氯化锂外其他5种金属盐均在不同程度上优化茶黄素的染色效果,优化媒染条件:氯化钴浓度6 g/L、温度30℃、时间80 min和pH 5;硝酸铝浓度1 g/L、温度50℃、时间30 min和pH10;氯化镍浓度4 g/L、温度80℃、时间80 min和pH5;四氯化钛浓度4 g/L、温度40℃、时间80 min和pH10;三氯化铁浓度1 g/L、温度80℃、时间80 min和pH7。此外,金属盐作为媒染剂媒染样品的强度及韧性均有一定的提升。
Taking ferric chloride,aluminum nitrate,titanium tetrachloride,lithium chloride,nickel chloride and cobaltous chloride as mordant,the effects of 6 kinds of metal salt on cotton cloth dyed with Theaflavins(TFs) by the method of bath mordant was studied.The K/S value,fading fastness and mechanical properties of dyed cotton cloth was adopted to determine the optimum processing conditions:metal salt concentration,dyeing time,dyeing temperature and mordant pH value.The results showed that 5 kinds of metal salt except lithium chloride could be mordant-dyed cotton cloth,and the optimized mordant conditions were as follows:C(cobaltous chloride) 6 g/L,temperature 30 ℃,time 80 min,pH 5;C(aluminum nitrate) 1 g/L,temperature 50 ℃,time 30 min,pH 10;C(nickel chloride) 4 g/L,temperature 80 ℃,time 80 min,pH 5;C(titanium tetrachloride) 4 g/L,temperature 40 ℃,time 80 min,pH 10;C(ferric chloride)1 g/L,temperature 80 ℃,time 80 min,pH 7.In addition,the breaking strength and toughness of the metal salt was increased in varying degrees as a mordant dyed cotton cloth.
