【摘要】 本文研究了提取自麻栎壳斗的植物染料(麻栎染料)的耐酸、碱稳定性,染浴pH值及铝、铁离子等环保型媒染剂对其染毛织物效果的影响,并且探究了其染色动力学。研究表明,麻栎染料在强酸性染浴(pH=3)中对羊毛织物直接性好,染色后毛织物得棕色,也可采用铝离子、铁离子对直接染色后的毛织物进行后媒染,以得到不同色相的毛织物,尤其是铁后媒染,可使棕色毛织物变为浅黑色;在染色温度100℃、染色时间250 min后,麻栎染料染色毛织物达到平衡。更多还原

【Abstract】 In this paper,the following aspects of the vegetable dye extracted from the cupule of Quercus acutissima Carr.were investigated:(1) the stability to acid and alkali;(2) the effects of the pH value in dye bath and the after-mordanting with aluminum and iron(Ⅱ) to the dyeing properties on wool fabrics;and(3) the kinetics during the dyeing processes on wool fabrics.The results suggested that:(1) the vegetable dye extracted from the cupule of Q.acutissima exhibited good dyeing properties to wool fabrics in strong acid dye bath(pH=3) and it can dye wool fabric by using direct dyeing method;(2) the after-mordanting method with iron(Ⅱ) was also available and it changed the color of the dyed wool fabrics from brown to pale black;and(3) the dyeing process on wool fabric got to a balance after keeping the dyeing process for 250 min at the temperature of 100 ℃.更多还原
