This change in the thermal behavior of the fabric can lead to buffer the post-exercise chill. During activity in a moderately cold environment clothing made of 100% wool fiber helps wearers to slow down evaporative and conductive cooling, which can provide more thermal and comfort sensation compared to 100% cotton, 100% viscose, and 100% polyester. Twelve males performed cycling in a controlled climate chamber of temperature:15 ± 0.5 °C, and relative humidity (RH):50 ± 5% followed by a drying phase in a windy environment by wearing full-sleeve t-shirts. Wool shirt was observed to hold a greater torso skin temperature (p < 0.05) than the other fiber types. Participants were asked a range of comfort-related questions at varying intervals. The temperature sensation was found (p < 0.05) significant for wool clothing. Moreover, participants rated wool shirt significantly (p < 0.05) as more comfortable during the post-exercise phase.}, journal={ERGONOMICS}, author={Abedin, Faisal and Denhartog, Emiel}, year={2023}, month={Nov} } @article{abedin_denhartog_2023, title={The Exothermic Effects of Textile Fibers during Changes in Environmental Humidity: A Comparison between ISO:16533 and Dynamic Hot Plate Test Method}, volume={11}, ISSN={["2079-6439"]}, url={https://doi.org/10.3390/fib11050047}, DOI={10.3390/fib11050047}, abstractNote={The exothermic effects of high regain fiber types have been described before; yet, there have not been reliable tests to demonstrate these effects on the human body. Most test methods focus on steady-state measurements; therefore, these exothermic effects during changes in environmental humidity are typically not analyzed or quantified. We have conducted a set of fabric tests that shows the connection between the exothermic effect of water vapor uptake and its consequence for heat loss through the fabric in transient conditions. We have performed the ISO:16533 standard test, a dynamic hot plate test developed by Naylor to measure the exothermic property of the fabric, and dynamic regain tests to connect the dots between these tests and the water vapor uptake phenomenon. Although the ISO:16533 test method tends to show the temperature increase in fibers, it cannot differentiate between the hygroscopic fiber (wool, viscose, cotton) types (p > 0.001). In addition, sensor size and sample folding techniques could impact the temperature increase. On the other hand, the Naylor hot plate test showed a greater difference in heat release among the fiber types (wool showed 20% higher heat release than viscose, 50% more than cotton), although the relative humidity changes in the chamber take time, which might not reflect a step-wise change in humidity. So far, these test methods have proven to be the most reliable for determining the exothermic behavior of textile fiber. However, these test methods still have limitations and cannot simulate realistic environmental conditions considering an instantaneous change in the environment. This paper reflects the comparison between the two test methods and recommends directions to accurately address the theory of water vapor uptake under dynamic conditions.}, number={5}, journal={FIBERS}, author={Abedin, Faisal and DenHartog, Emiel}, year={2023}, month={May} } @article{rahman_khalil_solaiman_khan_sarkar_abedin_kamal_mamun_2015, title={Investigation on Physico-Chemical Properties of 100% Cotton Woven Fabric Treated with Titanium Dioxide}, volume={3}, ISSN={2330-8753}, url={http://dx.doi.org/10.11648/j.ajac.20150302.15}, DOI={10.11648/j.ajac.20150302.15}, abstractNote={This paper represents an approach to observe the physico-chemical effects of titanium dioxide (TiO2) applied on 100% cotton woven fabric. Cotton fabric was treated with TiO2 by exhaustion method and followed by necessary curing and washing processes. The treated fabrics were then analyzed by Scanning Electron Microscope (SEM) and the tensile strength, pH and absorbency of the treated and untreated fabrics were examined. It was found that titanium dioxide impairs the hand feel and absorbency of 100% cotton woven fabrics, wetting time of all treated fabrics increased gradually than untreated fabrics. The treatment increases the tensile strength of 100% cotton woven fabrics. The treatment with titanium dioxide also kept the pH of the fabric in acidic medium.}, number={2}, journal={American Journal of Applied Chemistry}, publisher={Science Publishing Group}, author={Rahman, Md Mostafizur and Khalil, Elias and Solaiman, Md. and Khan, Mubarak Ahmad and Sarkar, Joy and Abedin, Faisal and Kamal, A.H.M.Asif and Mamun, Rajib Al}, year={2015}, month={Apr}, pages={65–68} } @article{abedin_maniruzzaman_sina_khalil_2014, title={Effect of Gauge Variation of Circular Knitting Machine on Physical and Mechanical Properties of Cotton Knitted Fabrics}, volume={3}, ISSN={2325-0100}, number={4}, journal={International Journal of Textile Science}, publisher={Scientific & Academic Publishing}, author={Abedin, Faisal and Maniruzzaman, K.M. and Sina, Ahmad Saquib and Khalil, Elias}, year={2014}, pages={70–75} }
