Garment comfort
consists of three aspects: thermal and water comfort, touching comfort and
visual comfort. Both touching comfort and visual comfort can be measured by
human body contact, while thermal and water comfort, as the most important
feature, can only be measured by way of the professional device--sweatingguarded hotplate. 80% energy consumed by human activities turns to heat, and
90% of the energy will be dissipated, that’s why textile thermal resistance
plays quite important role in maintaining human body temperature.

Human body heat dissipating methods are
various like radiations, conductivity, convection, besides, surface sweat evaporation
can stimulate vapor diffusion and people will feel comfortable. If garments
prevent water evaporation, then moisture content between skin and apparel
increasing, vapor will accumulate and condense to water, people will feel quite
uncomfortable. Garments thermal resistance and water vapor permeability of sweating guarded hotplate test exert
great influence on heating exchange between human body and environment. Therefore,
measuring these two factors can predict apparel thermal comfort in different
environments.

Sweating guarded hotplate is especially popular
among work wear such as firefighters, military police uniform and sport wear. For
more sweating guarded hotplate information, QINSUN Instruments can offer professional
guide.
