Analysis of the Thermal Comfort Properties and Heat Protection Performance of Cotton/Nylon-Kermel Fabrics

In this research, fire and radiant heat protection and thermal comfort properties of cotton/nylon-Kermel blended woven fabrics, were utilized to predict the thermal comfort and protection limit of this fabric structure based on Woo and Barker developed model. The results showed that the porosity, the air permeability and the thermal resistance increased with Kermel fiber blend ratio. Conversely...

Structure Development during the Heat-Draw Process of Nylon 66 Fiber by Synchrotron X-ray Diffraction

On-line studies of structural development during continuous drawing of nylon 66 fiber at different temperatures were carried out using synchrotron wide-angle X-ray diffraction (WAXD). A unique image analysis method was introduced to analyze the two-dimensional (2D) WAXD patterns. The quantitative fractions of crystal, mesomorphic and amorphous phases were obtained. In this study, the Brill tran...

Flexural strength of heat-polymerized polymethyl methacrylate denture resin reinforced with glass, aramid, or nylon fibers.

STATEMENT OF PROBLEM Despite the favorable properties of conventional PMMA used as a denture base material, its fracture resistance could be improved. PURPOSE This in vitro study was performed to determine whether the flexural strength of a commercially available, heat-polymerized acrylic denture base material could be improved through reinforcement with 3 types of fibers. MATERIAL AND METH...

Modeling Exposures of a Nylon-Cotton Fabric to High Radiant Heat Flux

American soldiers and marines involved in the recent conflicts in Iraq and Afghanistan have suffered increased incidence of burn injury, often as a direct result of exposure to improvised explosive devices. In this work, a one dimensional numerical pyrolysis model for transient heat conduction, incorporating material transformations described by chemical kinetics, is used to investigate the res...
