Capped 1,2-propylene terephthalate-polyoxyethylene terephthalate polyesters useful as soil release agents are disclosed. Preferred polyesters have the formula: ##STR1## wherein each R.sup.1 is a 1,4-phenylene moiety; the R.sup.2 are essentially 1,2-propylene moieties; the R.sup.3 are essentially the polyoxyethylene moiety--(CH.sub.2 CH.sub.2 O).sub.q --CH.sub.2 CH.sub.2 --; each X is ethyl or preferably methyl; each n is from about 12 to about 45; q is from about 12 to about 90; the average value of u is from about 5 to about 20; the average value of v is from about 1 to about 10; the average value of u+v is from about 6 to about 30; the ratio u to v is from about 1 to about 6.
