What kind of material is Thermal Grain™ mentioned in the description?
This is asked when wondering what specific principles and functions the fabric has after seeing the name of the proprietary material written in the half tights description.
It is a fabric developed in-house by GOYOWEAR, combining a material recycled from discarded coffee grounds with heat-generating yarn that creates heat when moving.
It starts from waste that used to be discarded, buried, or incinerated, but when you wear it and run, it gains heat from movement to create warmth[1][2]. Thermal Grain™ developed in-house by GOYOWEAR is a circular material that reduces coffee grounds destined for landfills or incineration and minimizes the use of chemicals[3][4].
In addition, a heat-generating yarn that captures energy from physical activity to boost warmth is used alongside it[5]. Generally, functional heat-generating yarn refers to a yarn that helps maintain temperature by absorbing frictional heat or body heat generated during exercise, making it better for retaining warmth when moving your body and sweating rather than standing still. Furthermore, it incorporates natural UV protection necessary for outdoor exercise and deodorizing power that reduces sweat odors[6].
The specific fiber composition ratio and UV protection factor of the Thermal Grain™ fabric have not been confirmed yet.
