- ##STR13## wherein (1) the ring can have all positional isomer arrangements;
- (2) R is selected from the group consisting of ##STR14## (3) R.sup.1 and R.sup.2 are independently selected from the group consisting of hydrogen and --CH.sub.3 ;
- (4) n and m are independently selected from an integer of 0 to 3;
- (5) p is an integer of 6 to 23;
- and
- (6) q is an integer of 3 to 11;
- (b) drying the polyester fabric until the fabric is dry to the touch;
- and
