    Publication number: 20030229946
    Abstract: Durable polymeric surfactants for imparting capillarity to a synthetic textile fiber or nonwoven synthetic textile are provided The polymeric surfactants do not tend to readily wash off the textile after repeated contact with aqueous fluids. The polymeric surfactant compositions include compounds that are a reaction product of polyhydroxycarboxylic acid having a molecular weight from about 600 daltons to about 2,100 daltons and an end-capped polyalkylethylene glycol having a molecular weight from about 300 daltons to about 5,000 daltons. The polymeric surfactant compositions may also include compounds that are a reaction product of polyhydroxycarboxylic acids having a molecular weight from about 600 daltons to about 2,100 daltons and polyalkylethylene glycols having a molecular weight from about 200 daltons to about 3,200 daltons.
