Chemical Hand Warmers in Protective Gloves: Design and Usage

Abstract

Heated gloves have been gaining popularity due to increasing work safety demands. The objective of the present work was to evaluate the effects of the presence of chemical hand warmers in protective gloves. The study involved three types of gloves appropriate for work activities performed in cold environments. Several hand warmer variants were designed, differing in terms of shape and location within the glove, which are of great relevance to the comfort of use. Manual dexterity tests were designed to approximate real conditions of the work environment, allow for simulation of occupational activities, and involve various aspects of manipulation.

Multilayer Nonwoven Inserts with Aerogel/PCMs for the Improvement of Thermophysiological Comfort in Protective Clothing against the Cold

“…A similar effect is achieved by using chemical heaters for clothing. The heat release occurs as a result of a chemical reaction that takes place between the chemical substances enclosed in the packages after their activation, e.g., by temporary kneading [ 3 , 6 , 7 ]. The lifetime of such inserts is limited.…”

Experimental Investigation of the Properties of Laminated Nonwovens Used for Packaging of Powders in Mineral Warmers

“…Laminated nonwovens are applied as packaging materials, preventing the ingress of external factors and improving comfort in contact with the human body. Mineral warmers, which operate on the principle of iron oxidation, are used as inserts in protective and sports garments to increase thermal comfort in cold environments [5][6][7][8][9].…”
