媒染剂和染料用量对红土染料染色棉织物色牢度的影响

Effects of mordant and dye concentration on durability of red soil dye on cotton fabrics

从红土中提取天然染料并将其应用于棉织物。改变媒染剂用量和染液用量进行染色试验。结果表明,与不使用媒染剂的试样相比,使用媒染剂的天然红土染色织物试样表现出较好的耐水洗、耐光和耐摩擦色牢度,且色牢度随着媒染剂用量的增加而提升。染料用量的增加未导致织物试样的色牢度明显提升。

Natural dyes were extracted from red soil and the dye was applied on cotton fabric.The concentration of mordant and the concentration of dye were varied.The natural red soil dyed samples with mordant exhibits good color fastness to washing,light and rubbing than compare with the samples dyed without mordant,and it increase with higher concentration of mordent.The increase in concentration of dye,does not influence the fastness of the fabric.
