Abstract
Poly(ethylene terephthalate) (PET) fabrics were dyed with a series of ethoxylated alkylaminoanthraquinone dyes synthesized by the reaction of 1-aminoanthraquinone with poly(ethylene glycol) via a series of methylene spacer, and their hydrophilicity and durability to laundering were investigated. The results obtained are as follows: 1) Ethoxylated alkylaminoanthraquinone were successfully exhausted on PET fabric without any aid of chemical auxiliary. 2) The wettability of the dyed PET fabric was increased with the length of ethoxylate chain. 3) The durability of the wettability was good enough as to maintain the initial wettability even after 30 repeated launderings.
