分散染料无水染色涤纶纱线工艺探究
Research on the process of waterless dyeing of polyester yarns with disperse dyes
摘要
Abstract
Traditional dyeing methods for polyester require a lot of water and heat energy consumption and cause serious damage to the environment.At present,the current polyester waterless dyeing process still has some problems such as high dyeing pressure,easy contamination of equipment and high cost.The five brands of disperse dye inks A,B,C,D and E are used to dye a certain amount of polyester yarns by centrifugal homogeni-zation method,and a new waterless dyeing process of polyester yarn is explored,which does not fade after washing and does not stain after soaping.The results show that different brands of disperse dye inks and the cor-responding fixing time have important effects on the washing fastness,color depth and soap-staining properties of dyed yarns.The optimal inking amount of cyan dye inks of brands A,C and D for 300 m polyester yarns is 0.3ml,and the best fixation process is to keep the temperature at 195℃for 4 min.Polyester yarns dyed using this method exhibits characteristics of being colorfast to washing and resistant to staining during soaping.The colorfastness rating is at level 4 or above.关键词
