摘　　要：采用热溶染色法对PLA织带进行染色。研究发现,PLA织带在130℃下热溶固色180 s可达到较好的染色效果;同时添加2 g/L以内的黏合剂LB可在不影响颜色的情况下显著提升织带的色牢度;与PET织带热溶染色性能相比,PLA织带显色性更好;相对于浸染工艺,热溶染色PLA织带固色率和色牢度更佳。Thermosol dyeing of PLA ribbon is carried out.It is found that the PLA ribbon can achieve good dyeing results by thermosol fixation at 130℃ for 180 s.The addition of less than 2 g/L of adhesive LB can significantly improve the color fastness of the ribbon without affecting the color.Compared with the thermosol dyeing performance of PET ribbon,the color development of PLA ribbon is better.Compared with the dip dyeing of PLA ribbon,the fixation rate and color fastness of thermosol dyeings are better.
