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

Abstract

The unique structure of β-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, β-cyclodextrin modified with monochlorotriazine (β-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 β-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°C). The fragrance was retained in β-CD-MCT-treated cotton fabrics for 21 days in the same conditions.
