  Abstract:To solve the problems of low dyeing rate and easy damage to physical properties of polylactic acid fiber by conventional dyeing process,the problems of light dyeing and poor dyeing performance of polylactic acid fiber are improved by using the dope dyeing method of masterbatch and nano pigment.The effects of common dispersant and super dispersant on the dyeing effect,mechanical properties and heat resistance migration of nano pigment used in dope dyeing fiber are compared and analyzed.The results show that the polylactic acid fiber dyed by dope dyeing has bright color and good strength and elongation.The dispersed particle size of nano pigment by common dispersant is micron size,and the minimum size is about 5 μm,and the loss of strength and elongation of dyed fiber is about 10%,which is slightly better than that of conventional dyeing process.But the heat resistance migration of fiber is poor,which is not conducive to subsequent processing.The dispersed particle size of super dispersant is nanoscale,and the loss of strength and elongation of dyed fiber is not more than 1%,and the fiber has good heat resistance migration,which can maintain color stability in processing and post-treatment.
Key Words:polylactic acid fiber;dope dyeing;nano pigment;dispersion;strength and elongation;heat resistance migration
