Effect of Configuration of Protective Fabrics on Thermal Protective Performance under Steam Exposure

Abstract

A novel steam simulator was employed in this study to evaluate thermal protective performance of protective clothing while exposing to steam hazard. Single-and double-layer fabric systems were selected, and different configurations of moisture barrier were exposed to steam hazard for investigating the effect of configuration of protective fabrics on the thermal protective performance. The skin bio-heat transfer and Henriques burn integral models were used to predict the required times to reach 2nd and 3rd degree skin burn. The results demonstrated that the thermal protective performance of protective clothing under steam exposure was determined by the air permeability, the thickness, the mass, and the surface properties of fabric. Even though the moisture barrier provided excellent protective performance for steam exposure, the configuration of moisture barrier presented a decisive influence on the role of moisture barrier. The findings obtained in this study provide technical data for the performance improvement of protective clothing under steam hazard.

The Potential of Double-Faced Polyester-Viscose Woven Fabric as a Porous Substrate for Direct-Coating and Multilayer Concept

“…The substrate employed in this sensor exhibits a layered design structure meticulously arranged to provide optimal permeability. The arrangement of this stratified structure on the substrate creates a moisture barrier that has a substantial impact on the transfer of both liquids and vapors between the two fabric layers [4]. The three-dimensional simulation of a single-layer fabric was conducted with the assistance of the Wisetex application, employing 8 sets of warp A woven fabric with a weft yarn count of 90 strands per inch exhibits a higher density compared to fabrics with 80 and 70 weft strands per inch.…”

“…Generally, the absorption rate on the lower surface of the fabric is always faster when compared to the absorption rate on the upper surface of the fabric [6]. This is because the fabric is placed horizontally during the measurement and gravity assists in increasing absorption on the lower surface of the fabric [4]. by the effectiveness of capillary pore distribution within the fabric [19,20].…”

“…This fabric has a layered structure composed of two groups of warp threads, causing the upper and lower surfaces of the fabric to be more separated compared to typical fabrics. The configuration of this layered structure on the substrate establishes a moisture barrier that significantly influences the movement of both liquid and vapor between the two fabric surfaces [4,5]. This is expected to effectively retain the electrode paste on one surface of the fabric during the fabrication process [6].…”
