Article
Under dynamic wear conditions, moisture management and heat transfer behaviour of clothing between the human body and its environment are very important attributes for comfort and performance. Especially considering heavy works like firefighting, it is important to analyse liquid moisture management and thermal comfort properties of fabrics that in...

In this study, the loss of the silver content was determined accurately when silver plated nylon electrodes dedicated to a measurement of human physiological parameters are washed with detergents containing bleaching agents. Thermogravimetric analysis and morphological observations based on SEM images have been conducted to determine the quantity o...
Article
The Skin Model is modified with a frame in order to model the microclimate which is present between the skin and the clothing. The aim of the study is to design and instrument the system by allowing dynamic control of moisture management as a function of time. Resistive humidity sensors are placed at 4 locations in the frame to measure the transfer...
Article
In this study, the sorption and desorption isotherms from the dynamic vapor sorption test are modeled by using six different models, that is, the (i) BET (Brunauer–Emmett–Teller), (ii) modified BET, (iii) GAB (Guggenheim–Anderson–Boer), (iv) PEK (parallel exponential kinetics), (v) HH (Hailwood–Horrobin), and (vi) Nelson and Young models. The appli...

Optimal comfort will enable the wearer to work efficiently over long periods of time and help to protect the body from imminent overheating. The thermal performance of fire fighters' protective clothing is primarily based on the thermophysical properties of the materials that are used to construct the clothing. In this study, we have used new fire...
Article
This study presents the development of a textile radiative heat fluxmeter (TRHF) which was designed by weaving technology. The first part of this work focuses on a textile heat fluxmeter (THF) which was developed with the principle of a gradient heat fluxmeter. In order to transform this THF to a TRHF, a polymer with different graphite concentratio...

This study reports on the impact of textile properties on thermal comfort. The fabric weight, thickness, porosity, moisture regain, air permeability and density have been considered and correlated to the thermal and water vapour resistance, permeability index, thermal conductivity and effusivity, and moisture management capacity. Results suggest th...

The impact of thermo-hydric behavior of underwears were studied on comfort. The Pearson method is used to make a correlation between physical and thermo-hydric properties of fabrics. Three parts have been studied, i.e. (i) thermal properties, (ii) hydric properties, and (iii) coupling between thermal and hydric properties. It has been observed that...
Chapter
The existing heat fluxmeters are rigid and prevent mass transfers since they are nonporous, which results in inaccurate data. By the integration of electroconductor wire (monoconductor or biconductor), a textile heat fluxmeter was developed by a weaving process; through its porous structure this heat fluxmeter allows transfer of moisture. In this s...
Article
This study presents the effect of a woven fabric's material, i.e. polyester (PES), 70/30 polyester/cotton (PES/CO) blend, and its structure, i.e. plain, twill, satin, on the heat and mass transfer properties with regard to development of a textile heat flux sensor. The main purpose of this study is the identification of the most appropriate textile...

Project
Nowadays, it has become essential to have a more effective insulation to avoid energy loss (building, transport...). It may result in a lack of ventilation that can lead to an increase in the concentration of pollutants in indoor air, such as Volatile Organic Compounds (VOCs) harmful to human health. Different approaches have been proposed to eliminate/reduce this problem: ventilation, purification by adsorption, depolluting plants... However, the development of methods for degradation in situ of pollutants seems much more effective and beneficial long-term. Our project is part of this process and is to develop materials for degradation of VOCs by photocatalytic effect from indoor air, ideally in H2O and CO2 in the visible and without additional external power supply.

Le projet a pour objectif le développement d'un textile comprenant des particules photocatalytiques à base de TiO2 dopé actives sous rayonnement visible. Le système qui sera développé permettra la dégradation de polluants COV de l'air intérieur en continu d'une manière simple et sans apport d'énergie extérieur supplémentaire. La solution proposée en matière de dépollution de l'air contribuera donc à l'amélioration continue de la QAI. Par ailleurs, une bonne qualité de l'air à l'intérieur des lieux de travail ou de vie a un effet positif démontré sur la diminution du taux d'absentéisme, la productivité et le bien-être des occupants. D'autre part, le besoin de solutions techniques adaptées d'amélioration de la QAI est grandissant et son marché économique est très important. A l'issue de la recherche, les procédés mis au point pourront être transférés aux nombreuses entreprises du secteur de textile de la zone ainsi qu'aux entreprises spécialisées dans l'épuration et l'assainissement de l'air. Les nouveaux produits ainsi développés assureront un avantage compétitif à ces mêmes entreprises et un maintien (voire un renforcement) de l'ancrage de ces industries dans nos régions. Pour atteindre l'objectif, nous procédons par la synthèse de nanoparticules de TiO2 dopées puis leur integration dans des nanofibres de cellulose fabriquées par ailleurs. Finalement, le nanocomposite ainsi préparé sera assemblé sur le support textile par un procédé bien adapté. Les supports textiles à fonctionnaliser sont déjà présents dans nos lieux de vie et par conséquent, la solution proposée n'engendrera pas de coût supplémentaire.
