Abstract: Poly(lactic acid) (PLA) is the first melt-processable, renewable, sustainable and biodegradable natural-based synthetic fibre. It has a broad range of uses and combines ecological advantages with outstanding performance in textiles. PLA fibre, as an aliphatic polyester, can be dyed with disperse dyes. Apart from the limited number of commercial disperse dyes, disperse dye exhaustion on PLA is generally lower than that on poly(ethylene terephthalate) (PET). In this study, new heterocyclic disazo disperse dyes, substituted with methyl, nitro and chloro groups at their ortho-, meta- and para- positions, synthesised in our previous study, were applied to PLA and PET fibres to examine their dyeing performance, and colour fastness and dye exhaustion properties. Different shades of yellow, orange, reddish brown and brown were obtained. Most of the synthesised novel heterocyclic disazo disperse dyes exhibited good build-up properties with high K/S levels on both fibres. Para- bonding substituent provided higher K/S values than meta- and ortho- positions for –NO2 and –Cl substituents for both fibres. Overall, the most synthesised novel heterocyclic disazo disperse dyes in this study exhibited good build-up properties with high K/S, exhaustion and wet fastness levels on both PLA and PET fibres. © 2020 Society of Dyers and Colourists
