    摘要: A new and useful indigo-dyeable polyester is disclosed, and process for making same, for which a suitable polyester has had applied to its surface an amount of a suitable indigo dye retaining compound effective to provide said polyester with indigo fastness properties similar to cotton. The new indigo dyeable polyester may be employed in the manufacture of a staple material blended with cotton in predetermined amounts depending on the end use desired, e.g., 50:50 by weight for cotton denims (e.g., jeans). Preferable indigo dye retaining compounds comprise monomers dioleylamine and dicocoamine. Other suitable indigo dye retaining monomers are disclosed, inter alia, having the formula: ##STR1## wherein R.sub.1 is alkyl or alkenyl of about 10-18 carbons; R.sub.2 is alkyl, alkylaryl, or alkenyl of about 8-18 carbons, R--CH.sub.2 --NO.sub.2, R--CH.dbd.NH, where R is alkyl or alkenyl from one to eighteen carbons; and R.sub.3 is hydrogen or alkyl from one to about twelve carbons. A process is also disclosed for treating a meltspun suitable polyester fiber with an amount (e.g., about 0.25%-2.0% by weight) of a suitable indigo dye retaining compound effective to provide said polyester fiber with indigo fastness properties similar to cotton.
