樟树落叶提取液对羊毛织物染色的工艺探讨

Research of dyeing on wool fabric with dry leaves of camphortree extraction

研究了樟树落叶提取液对羊毛织物的染色。讨论了染色pH值、染色温度、染色时间、硫酸钠质量浓度、樟树叶质量浓度、媒染工艺等对羊毛织物染色效果的影响。分析染色羊毛织物的K/S值及CIE的Lab值,得到樟树落叶提取液对羊毛织物直接染色的优化工艺为:染色pH值3.50左右、染色温度100℃、染色时间75 min,浴比1∶50。硫酸铜及硫酸亚铁媒染可获得不同颜色特征的染色织物,其中后媒染的颜色最深,媒染可提高染色羊毛织物的耐皂洗及耐日晒色牢度,但对耐摩擦色牢度略有影响。

The dyeing of wool fabrics with extraction of dry leaves of camphortree was studied. Factors exerting influence on dyeing results on wool fabric such as dyeing pH value, dyeing temperature, dyeing time, Na2SO4 concentration and mordant dyeing were discussed. The K/S and CIE Lab values of the dyed wool fabrics were investigated, the optimum conditions for the direct dyeing on wool fabric were pH value 3.50, dyeing temperature 100 ℃ , dyeing time 75 min, liquor ratio 1： 50. Different hues wool fabrics could be obtained through mordant dyeing by CuSO4 and FeSO4. The post-mordant dyeing gave the great depth of shade. The colour fastness to washing with soap and fastness to light could be improved, but eolour fastness to rubbing was a little influenced by mordanting.
