Morphology and Properties of PET Fabric Finished by β-Cyclodextrin and Citric Acid

Polyethylene terephthalate (PET) fiber is a kind of widely used textile fiber due to its some desirable properties. However, it limited its application in clothing because of poor hydrophilic property and high static electric. In order to improve hydrophilic and antistatic properties of PET fabrics, β-cyclodextrin (β-CD) was finished onto them with citric acid (CA) as crosslinking agent. SEM showed that β-CD was finished successfully onto PET fibers. Moisture liberation curve indicated that the finished PET fabrics possessed favorable hydrophilic property. However, water vapor transport property of the finished PET fabrics slightly decreased. Antistatic property of PET fabrics finished by β-CD acquired improvement. In addition, tensile properties of PET fabric also were enhanced after finishing.
