Modification of cotton fabrics with β-cyclodextrin derivative for aroma finishing

The unique structure of beta-cyclodextrin to form inclusion complexes has led to important commercial applications in several areas such as the pharmaceutical, cosmetic, and flavour industries. In this research, beta-cyclodextrin modified with monochlorotriazine (beta-CD-MCT) was synthesised and applied as surface modification on cotton fabrics. The possibility of entrapping sandalwood oil as an aroma-finishing agent has been investigated. The Fourier transform infrared, tensile tests, and gas chromatography-mass spectroscopy measurements were used to investigate the effects of the treatment. It was found that beta-CD-MCT can be fixed to cotton fabrics with the pad-dry-cure method at high temperature. No loss of tensile strength of the treated fabrics was found. The fragrance disappeared from untreated cotton after 8 days when stored at ambient temperature (30 degrees C). The fragrance was retained in beta-CD-MCT-treated cotton fabrics for 21 days in the same conditions.
