Introduction
The sweating warm body dummy test technology developed by our company is the optimal technology for objectively evaluating the overall thermal resistance and moisture resistance performance of garments, which is widely used in the fields of garments, aerospace, fire fighting, petroleum, traffic safety, occupational health, etc. Especially in the evaluation of the warmth performance of garments, the study of warmth mechanism of garments, and the development of occupational protective garments, it plays an important role and is the recognised advanced equipment essential to the study of ergonomics of garments. It is recognised as an indispensable advanced equipment for clothing ergonomics research. It is recognised as an indispensable advanced equipment for garment ergonomics research. It is an international cutting-edge technology at the intersection of garment science, human bionics and biophysics.
