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.

Single-Sided Jacquard Knit Fabric Development and Seamless Ski Underwear Zoning Design based on Body Mapping Sportswear

“…At the same time, it can accelerate the sweat excretion and evaporation when the human body sweats. This is consistent with the conclusion of Kinnicutt et al [17]. Combined with the functional superfine polypropylene fiber, the functional superiority of yarn and fabric structure can be further maximized.…”

“…The impact of 3D knitted garments orientated by map on thermoregulation using an infrared scanning imager was investigated [17]. Temperature changes from the skin and outside of the garment indicated that the raised fabric structure will regulate the individual skin temperature by changing the microclimate of the torso area, with better skin temperature regulation ability than ordinary knitted fabric.…”

Elucidation of the Thermal Insulation in Textile Materials

“…It was indicated that a 3D textured knitting shirt would be superior to non-3D textured knitting shirt in thermal insulation performance. As shown in Figure 1, 8 with regard to the property of thermal insulation, the difference between a 3D textured knitting shirt and a non-3D one is similar to the difference between a thicker shirt and a thick one. In this way, the conclusion is in agreement with the previous.…”

Thermal Energy Generating Activewear Designs for Millennials

“…A FLIR T420 thermal camera was used to collect the body heat data throughout 5 minutes intervals during the physical activities. The participants were provided with 100% cotton t-shirts because according to Kinnicutt and Domina (2010), next-to-skin (NTS) tended to impact regular skin temperatures under hot condition and cotton is a good breathable fabric. The retrieved body heats were compared throughout different body parts and movements to examine the placements that generate the most heat.…”
