摘要 文中采用荆芥色素对锦纶针织物进行染色,探讨了荆芥色素染色对锦纶针织物染色性能和防紫外线性能的影响,测试了染色织物上染百分率、颜色特征值、UPF指数、紫外线透过率和染色牢度。结果表明,当荆芥色素用量为50mL/L时,直接染色最佳工艺为pH值2.00-4.00,温度100℃,保温染色60min;染色后锦纶针织物的染色牢度均达到3级以上;当荆芥色素用量为100mL/L时,染色锦纶具有优异的防紫外线性能,UPF值达30.00以上。 Natural dyes are easily biodegradable, rich in resources, and have a certain function. In this paper, the Nepeta pigment was used to dyeing of nylon fabrics. The effects of dyeing pH, temperature, time and dyes dosage on the dyeing and anti-UV performance of nylon fabrics were investigated. The dye uptake, color characteristics value, UPF index, UV transmittance and color fastness of dyed fabrics were tested. The results show that when the dosage of pigment was 50 mL/L, the optimum process for directly dyeing nylon fabric was pH 2.00-4.00, dyeing at 100 ℃ for 60 minutes, the color fastness of dyed polyamide fabrics was up to grade 3.00. When the amount of Nepeta pigment is 100 mL/L, the dyed nylon has excellent anti-UV performance and the UPF value is over 30.00.
