Black Versus Gray T-Shirts: Comparison of Spectrophotometric and Other Biophysical Properties of Physical Fitness Uniforms and Modeled Heat Strain and Thermal Comfort

摘要: Abstract : This work modeled and compared the heat strain discomfort differences between black gray t-shirts. Biophysical properties were measured for 5 ensembles using a sweating thermal manikin. These results showed little existed across each of ensembles, where at 0.4 m/s ranges 0.88 0.92 clo evaporative potential (im/clo) ranged from 0.51 0.54. Spectrophotometric measures differed reflection () 0.24 0.49, absorption 0.5 0.75, transmission 0.01 0.04. Predictive modeling that responses similar all ensembles. While overall wicking shirt had generally better least favorable values; in impositions to human are relatively negligible. Similar predictions, sensation (discomfort) very difference clothing Results support interest Army purchasing implementing replacement former physical fitness t-shirt with new t-shirt.
