Abstract:

In order to study the function of electrically heated gloves in extremely cold environments, electric-heating protective gloves were developed for resisting extreme cold. The electric-heating material was fabricated with metal fiber and carbon nanotube film. Infrared thermal imaging camera was used to conduct experiments of the electric-heating protective gloves, and a human ergonomic experiment was carried out through screw-and-nut assembly operations in an extremely cold environment of -30 ℃. At the same time, the subjective evaluation of heat and pain was recorded. The results show that electric-heating protective gloves made from both metal fiber and carbon nanotube film demonstrate good heating performance, and can both be heated up to the highest designed temperature in 60 s at room temperature. In the extremely cold environment of -30 ℃, both electric-heating protective gloves can increase the number of screws to be screwed within the specified time, indicating work efficiency improvement. Based on the subjective evaluation of heat and pain, electric-heating protective gloves have a significant effect on resisting cold.

Key words: electric-heating protective glove, metal fiber, carbon nanotube film, ergonomic experiment, thermal imaging experiment
