【摘要】 板栗壳中的色素是一种天然植物染料,文章通过对提取液吸光度的测试及其染色毛织物K/S值的测试与分析,讨论了染料的提取工艺及毛织物采用板栗壳天然染料染色时p H值、染料用量、染色温度、染色时间对织物染色效果的影响。结果表明,Na OH溶液是板栗壳色素提取的最佳试剂,板栗壳天然植物染料对精纺毛织物染色的最佳工艺为:染液p H值3,染料用量60 m L/L,染色温度80℃,染色时间100 min。在此工艺条件下染色毛织物可以获得较好的染色效果,色牢度能够达到服用要求。更多还原

【Abstract】 The pigment in the chestnut shell is a natural vegetable dyestuff. In this paper,the absorption of the extracted solution was tested and the K / S value of the dyed worsted fabric was tested and analysized. On the base of it,the extracting process of the chestnut shell pigment and the dyeing factor which the worsted fabric was dyed by it were disscused. The result showed that the best agent extracted the pigment from the chestnut shell was the Na OH solution. The better dyed result could be achieved that the worsted fabric dyed by the dyeing solution extracted form the chestnut shell when the dyeing process was advisabe. The optimized process was: p H value 3,dyestuff dosage 60 m L / L,80 ℃and 100 min. And the dyed fastness can meet the demand of the fabric used on the cloth.更多还原
