Abstract
A novel series of silicone-modified polyesters (SMP-polyester) has been prepared by the reaction of organopolysiloxane with hydroxy terminated polyester. The polyesters are obtained by the polymerization of maleic anhydride (MA) and polyethylene glycols (PEGs). These SMP-polyesters are water-soluble and can be used as auxiliaries in the dyeing process because they exhibit good surface activities such as surface tension, low foaming and wetting power. The SMP-polyesters can be successfully employed as an auxiliary in dyeing polyester fabric with disperse dyes at elevated temperatures without occurrence of creases.
