Claim 13:
14. A process for washing a fabric comprising the step of contacting the fabric with a polyester comprising two or more structural units (a1), one or more structural units (a2) and either one or two terminal structural groups (a3), wherein
each G1 is independently (OCnH2n) with n being a number of from 2 to 10,
R1 is a C1-30 alkyl,
p is, based on a molar average, a number of from 1 to 200,
q is, based on a molar average, a number of from 0 to 40,
where
the (OC3H6)— and (OC2H4)-groups of the terminal group (a3) may be arranged blockwise, alternating, periodically and/or statistically,
either of the groups (OC3H6)— and (OC2H4)— can be linked to R1— and —O,
adjacent structural units (a1) are connected by the structural unit (a2), in the case that only one terminal group (a3) is present in the polymer, the other terminal group is selected from the group consisting of OH, OCH3, and G1OH and
both terminal groups may be only linked to a structural unit (a1).
