Description
Summary:An organic Phase Change Material (PCM) possesses the ability to absorb and release large quantity of latent heat during a phase change process over a certain temperature range. This paper presents results related to thermo-physiological efficiency of special underwear with organic PCM integrated in textile through microencapsulation process. The efficiency of PCM underwear was tested through physiological examinations in simulated high-temperature conditions, where test-subjects were voluntarily exposed to heat stress tests wearing NBC protective suit with PCM underwear (option "THERM") and without it (option "NoTHERM"). It can be concluded that wearing a PCM textile clothes under NBC protective suit, during physical activity in high-tempearture conditions, reduces sweating and alleviates heat stress manifested by increased core and skin temperature and heart rate values. Keywords: phase change, microencapsulation, protective suit, underwear, physiological measurements. Materijali koji menjaju fazno stanje (PCM) organskog tipa imaju sposobnost apsorbcije i emisije velikih kolicina toplotne energije tokom procesa faznih promena (prelaza iz jednog agregatnog stanja u drugo). Upotreba PCM u svrhe namenskog skladistenja energije ili stvaranja efekta toplotne izolacije je naucno potvrcena i industrijski testirana. U novije vreme narocito raste interes istrazivaca za nanosenje PCM na tekstilne materijale metodama premazivanja ili mikroenkapsulacije. U radu su prikazani rezultati ispitivanja termofizioloske efikasnosti specijalnog rublja sa organskim PCM integrisanim u tekstilni materijal kroz proces mikroinkapsulacije. Efikasnost PCM rublja a je testirana kroz proveru termofizioloskih parametara u vestacki simuliranim uslovima tople sredine (klima komora), gde su ispitanici izlozeni testovima toplotnog opterecenja pri nosenju ABH zastitne odece bez specijalnog rublja (opcija "NoTHERM") i sa PCM rubljem (opcija "THERM"). Moze se zakljuciti da nosenje odece za termoregulaciju bazirane na integraciji organskih PCM, ispod ABH zastitnog odela, tokom fizicke aktivnosti u toplim uslovima, umanjuje intenzitet znojenja i ublazava termalno opterecenje korisnika. Kljucne reci: fazna promena, mikroenkapsulacija, zastitna odeca, rublje, termofizioloska merenja
