Binding and release of odor compounds from textiles: Changing fiber selection for apparel

Abstract

Understanding odor volatiles known to constitute those emanating from the human body and how these interact with textiles is relevant to diverse interested parties because of changing fiber use, a better understanding of apparel life cycles including cleaning and the potential for fiber/textile re-use. This paper extends the application of our proton transfer reaction-mass spectrometry model system on adsorption and release behavior of fiber types typical of next-to-skin uses to include both viscose and other volatile organic compounds in body odor for which release has not previously been studied (hexanoic acid, acetone, cyclohexanone, hexanal, methyl butanoate, ethyl benzene, 1-octanol, decanal, butanoic acid). The current findings confirmed release patterns of different fiber types found in our earlier studies – low release of volatile organic compounds from cotton and wool, but higher release from polyester – and made a new finding of low release from viscose. Adsorption characteristics were different given the different volatile organic compounds analyzed. Viscose showed better adsorption characteristics for primarily polar volatile organic compounds, but was otherwise very similar to cotton.

Sweat and odor in sportswear – A review

“…In another series of studies, the body odor matrix was developed by mixing multiple selected VOCs at an optimized ratio to ensure an adequate detection signal for each. 88 , 89 , 90 The results confirmed the low release of VOCs from cotton and wool, but higher release from polyester, consistent with the earlier findings. 90 The adsorption characteristics of wool, cotton, and polyester fibers varied given the different VOCs selected for analysis in this series of research.…”

“… 86 This technique has been used for odor evaluation of textiles under the condition that the source of VOCs in the gaseous mixture is available from the literature or is already known. 87 , 88 , 89 , 90 Other techniques that have been reported include liquid scintillation counting and infrared (IR)-based spectrometer. The former was used to measure the adhesion/release of 14 C-labeled isovaleric acid, a representative substance of sweat odor, to/from knitted fabrics 91 ; and the latter was utilized to quantify the adsorption/emission of four representative VOCs (acetone, ammonia, acetic acid, and butyric acid) in polyester/wool blend fabrics.…”

Tobacco and Hot Pot Odor Adsorbed by Cotton, Wool, and Polyester Fabrics: Desorption Components and Dynamic Analysis

“…The study of tobacco 1 School of Textiles and Fashion, Shanghai University of Engineering Science, Shanghai, China smoke and hot pot odor from various fabrics has made some progress in analyzing odor components and the difference between fabrics. [5][6][7][8] Nonetheless, the fabric odor desorption research is minimal. The desorption process is also a dynamic process influenced by odorous molecules, fiber properties, fabric structure, and the external environment.…”

“…7,11,12 At the same time, the adsorption behavior of volatile compounds by fabrics is related to the compounds' content, structure, and characteristics, such as polarity and aromaticity. 6,13,14 McQueen has successively investigated the body odor intensity of cotton, wool, and polyester. The results showed that polyester has the highest odor intensity.…”
