The Microclimate in Protective Fire Fighter Footwear: Foot Temperature and Air Temperature and Relative Humidity

Irzmańska E.

Vol. 16, no. 2

75--79

The study material consisted of two models of protective firefighter footwear. The tests were conducted on subjects in a laboratory using an ergometric treadmill. The parameters of footwear microclimate were continuously recorded using T/RH sensors. For the leather footwear, the highest foot temperature was recorded in the 50th minute of the experiment (35.8°C in the dorsal region and 37.3°C in the plantar region) and for the polymer footwear in the 60th minute of the experiment (35.4°C in the dorsal region and 37.0°C in the plantar region). In the leather footwear, the temperature of the air surrounding the feet rose from 31.0°C to 35.4°C, and then declined, but did not return to the initial level during the rest period. In turn, in the polymer footwear, the temperature rose from 29.0 to 34.7°C, and then decreased to 33.7°C following the rest period. The highest relative air humidity was recorded in the polymer footwear (96.6%), while in the leather footwear it amounted to 91%. Testing the dynamics of the microclimate during footwear use provides complete information about changes in the temperature of the skin of the foot and the temperature and relative humidity of the footwear microclimate.

Praca dotyczy oceny dzianin wielowarstwowych przeznaczonych na wewnętrzne elementy obuwia. W ramach pracy zaprojektowano i wykonano 11 wariantów tekstyliów dwu i trzywarstwowych. Badano mikroklimat w obuwiu, w którym zastosowano opracowane materiały tekstylne. Opracowano nowe rodzaje wskaźników charakteryzujących mikroklimat w obuwiu. Zaproponowano również zastosowanie generalnego wskaźnika jakości, stosowanego do oceny tekstyliów, do klasyfikacji jakości obuwia pod kątem mikroklimatu jego wnętrza w trakcie użytkowania. Badania wykazały, że jest możliwe polepszenie właściwości obuwia przez zastosowanie dwuwarstwowych dzianin o właściwościach koduktywno-dyfuzyjnych i sorpcyjnych.

Research has been conducted on different modern multilayer knitted fabrics which might be applied inside footwear. Eleven alternative two and three layer textile materials were designed. Two different kinds of footwear were tested. The first ones were all plastic boots and the second ones were boots with leather upper. Research was concentrated on measuring the main factors of microclimate in the footwear. New indicators for assessing microclimate in footwear was been elaborated. The General Quality Factor, used for describing quality of textiles, has been adopted to evaluate and assess the quality of the footwear fabrics in dependence on its microclimate characteristic. The results of the research has shown that is possible to improve comfort of footwear by applying in it two-layer specially knitted fabrics with conductive-diffusion and sorption properties.
