Clothes that retain and emanate body odor feel uncomfortable and unclean; subsequently, the adsorption, desorption and removal amounts of malodorous compounds from fabrics with different polarities were examined. 1-Octen-3-one, octanal and isovaleric acid, which are important malodor compounds from the body, were used as volatile organic compounds (VOC). Samples were prepared with unfinished and β-CD finished cotton, nylon and PET fabrics. The amounts of VOCs retained on the fabrics were measured using headspace GC-MS; in addition, the odor intensity of the samples were evaluated by 10 trained panelists. The amounts adsorbed were estimated by weight gain; however, moisture was found to have a larger effect on the increase in weight than VOCs. The polarity of the VOCs decreased in the order of isovaleric acid, octanal and 1-octen-3-one. Despite the exceptionally large amounts of octanal adsorbed on the nylon sample, the amounts of malodorous compounds adsorbed on fabrics increased with the decreasing VOC molecular weight. The unfinished PET sample adsorbed more VOCs than the unfinished-fabric samples. The odor intensity was mostly weaker in the β-CD finished fabrics than in the unfinished fabrics. The odor intensity of the β-CD finished fabrics was lower than unfinished fabrics. The amount of VOCs that remained on the soiled fabric samples after storing in air for 24 hrs decreased with the increasing VOC vapor pressure. Most VOCs were removed by washing; however, more VOCs were left on the β-CD finished fabrics than unfinished fabrics. The intensity of the odor from the unfinished PET and β-CD finished fabrics was stronger and weaker, respectively, than that of other fabrics, even when the same amounts of VOCs remained.

β-CD is produced from starch through enzymatic degradation, and therefore it is an eco-friendly material and isn't harmful to the body. Nylon and PET fabrics are being increasingly used in active wear, as customers prefer this more comfortable and multifunctional material, as it provides antimicrobial properties and the removal of body malodor. That being said, β-CD is a proper material for these purposes. The β-CD was applied to a nylon 66 fabric and a PET fabric which were not pre-modified, and also applied to the fabrics that were modified with O 2 plasma or alkaline solution in order to increase surface roughness. The characteristics of these fabrics were studied. The PET fabric, which was pretreated with a NaOH solution, gains more weight than the PET fabric without pretreatment by the β-CD finishing. A crosslink between nylon 66 or the PET fiber and the β-CD finishing agent was not formed; however, the crosslink was formed in cotton fibers. This was confirmed using FT-IR and TGA analysis. The whiteness decreased little, the value of WT and MIU decreased, and that of B and RT increased with the β-CD finish. All of the β-CD finished fabrics had washing fastness after 10 washing cycles, even though nylon 66 and the PET fibers were not crosslinked with the β-CD finishing agent.

“…The same linking/crosslinking reagents can be used in the treating of different synthetic fibres. Polyester fibres were modified by -cyclodextrin using citric acid (Martel et al, 2002a), in our laboratories (Voncina et al, 2009), 1,2,3,4-butane tetracarboxylic acid was used as a linker. Within our current research we study the influence of -cyclodextrin on PET/cotton blend dyeing with disperse dye.…”
