Knit-in 3D mapping's effect on thermoregulation: preliminary results

Abstract

This study explored knit-in 3D mapping's influence on thermal comfort under different environmental conditions when in next-to-skin (NTS) garments. It was hypothesised that the knit-in raised geometric shapes would modify the microclimate in the torso region, allowing for better thermal management and keeping the wearer more comfortable than an identical NTS shirt without mapping. Thermal images were taken of the front and back torso regions of the NTS garments worn in wearer trials while exercising under hot and cold conditions. The data suggested that an NTS shirt with no mapping tended to regulate skin temperatures better under hot conditions, while an NTS shirt with knit-in mapping regulated skin temperatures better in cold environments. Skin and exterior garment temperature changes indicated that an NTS shirt with knit-in mapping retained more heat inside the garment, providing better insulative performance under cold conditions.
