“…To date, there are few published papers employing the ISO method. [36][37][38][39] Lee et al 36,37 used the gas detector method to evaluate the deodorizing properties of natural dyes and mordants used on cotton, silk, and wool fabrics with ammonia and acetic acid as challenge odorants. No correlation of odor reduction rates with sensory panels was conducted.…”

During use, textile items can develop unpleasant odors that arise from many different sources, both internal and external to the human body. Laundering is not always effective at removing odors, with odor potentially building up over time due to incomplete removal of soils and odorous compounds and/or malodors transferred during the laundering process. Textile odor can lead to consumer dissatisfaction, particularly as there are high expectations that clothing and textile products meet multiple aesthetic and functional needs. The problem of odor in textiles is complex and multi-faceted, with odorous volatile compounds, microorganisms, and precursors to odor, such as sweat, being transferred to, and retained by, fabrics. This article reviews the literature that specifically relates to odor within textiles. Methods for evaluating odor in textiles, including methods for collecting odor on textile substrates, as well as sensory and instrumental methods of odor detection, were reviewed. Literature that examined differences among fabrics that varied by fabric properties were reviewed. As well, the effectiveness of specific odor controlling finishing technologies to control malodor within textiles was also examined.

“…Zhu has Engineered Water Nanostructures (EWNS) that take advantage of the Reactive Oxygen Species (ROS, which are made up of hydroxyl and superoxide radicals), to remove odors produced by smoking, cooking, and sweating. 23 Current studies have not systematically considered the effects of these factors on the desorption of odor compounds from fabrics. 14 The literature review showed that an odor deposition and desorption dynamic model and analysis of the fibrous porous media are still unavailable.…”

Fibrous textiles readily absorb and desorb ambient odors. However, information on the composition and dynamic analysis of tobacco smoke and hot pot odors on fabrics during desorption is limited. This study used gas chromatography–mass spectrometry to analyze the desorption components of cotton, wool, and polyester fabrics exposed to these two odors, respectively. Then, a dynamic diffusion fabric structure model demonstrated the effect of airflow velocity and fabric porosity on nicotine desorption. Furthermore, we proposed mass diffusion coefficients with different molecular weights. The results showed that cotton fabrics with tobacco smoke released many low molecular weight compounds, while with wool fabrics significantly fewer compounds were detected than for the other two fabrics. Notably, 3-ethenylpyridine, a marker of tobacco smoke, was not detected in wool fabrics. For hot pot odor, cotton fabrics released more hexanal, nonanal, and anethole than wool and polyester, while wool fabrics released many β-pinenes. The numerical results of the dynamic model showed that the air inlet velocity significantly affects the nicotine concentration in the fabric. Meanwhile, the concentration of nicotine in fabrics with lower porosity decreased faster. A lower mass diffusion coefficient will cause odors to remain in the fabric. This study aimed at the composition and the dynamics of odor in fabrics and offers essential information and simple models for reducing unnecessary washing of textiles and odor resistance textile design.

“…There is an ever growing demand for specialty textile with one specific or multiple functions. Indeed, much has been achieved recently in this domain, namely textiles with odour elimination property ; Zhu et al, 2019), textiles for tissue engineering (Augustine et al, 2017) and wound healing (Kim, Cha and Gong, 2018), specialty textiles for military applications (Revaiah, Kotresh and Kandasubramanian, 2019), textiles for wearable electronics (Zhou et al, 2019), or catalytic applications (Fujii and Nakamura, 2013). Either woven or non-woven, cotton fibers remain the most used for clothing or specialty textiles due to the biodegradability, strong absorption capacity and porosity of these cellulosic fibers.…”

Clean water and sea free of organic pollutants are among the 17 United Nation Sustainable Development Goals (SDGs). In this global concern, the design of efficient, stable and recyclable catalytic materials remains challenging. In this context, we designed a series of mixed oxide-modified cotton fabrics and their related composites and interrogated their propensity to catalyze the degradation of methyl orange (MO) (a model pollutant). More specifically, functional cotton fabrics (CF) coated with RuO 2 -TiO 2 based-photocatalysts were obtained by dip-coating method at neutral pH. A layer of Polyaniline (PANI) was prepared by in situ oxidative polymerization of the aniline monomer on 4-diphenylamine diazonium salt (DPA) modified-RuO 2 -TiO 2 nanoparticles (NPs) coated-CF. The modified CFs catalyzed photodegradation and mineralization of MO under visible light, which depended on polyaniline mass loading. The CF/RuO 2 -TiO 2 /DPA@PANI obtained by in situ polymerization was the best catalyst due to DPA adhesive layer for polyaniline to RuO 2 -TiO 2 , and the strong attraction force between cellulose OH groups and anilinium during polymerization. The photodegradation rate constant was 0.101, 0.0532, 0.0775 and 0.0828 min -1 for RuO 2 -TiO 2 /DPA@PANI, RuO 2 -TiO 2 , RuO 2 -TiO 2 /PANI and RuO 2 -TiO 2 /DPA/PANI coated-CFs, respectively. The catalytic activity is favored by the photoactive species (OH  , 2 − ) which are formed by the excitation of electrons under visible light but also by the electronic exchanges at the RuO 2 //TiO 2 , RuO 2 -TiO 2 //PANI and RuO 2 -TiO 2 /PANI//CF interfaces.CF/RuO 2 -TiO 2 /DPA/PANI photocatalyst was stable under simulated sunlight and reusable three times. A mechanism is proposed to account for the efficient CF catalytic properties.
