Influence of Structure of Multilayer System on Functional Characteristics of Clothing for Firefighters

In this work investigation of influence of textile materials surface relief on protective and comfort properties of multilayer system used for firefighter's clothing was performed. For the research different types of multilayer systems consisting of outer shell, thermal and moisture barrier layers and lining were formed. After testing of fabrics mechanical and physical characteristics it was revealed that the structure of a separate fabric layer has a direct influence on protective and comfort properties of a multilayer system of firefighter's garment. In order to decrease a total weight of the protective garment, multilayer systems formed of lower area density fabrics having relief surface were compared to the systems having flat surface structure. The results showed that systems composed of relief structure fabrics ensured the required level of protection creating additional air gaps, also low weight of the systems improved wearing comfort properties.Original Abstract: Darbe atliktas ugniagesio aprangos daugiasluoksnio paketo apsauginiu ir devejimo komforto savybiu tyrimas, panaudojant paketo strukturai reljefinio pavirsiaus tekstiles medziagas. Tyrimui buvo suformuotos kelios skirtingo pavirsinio tankio daugiasluoksniu paketu strukturos, susidedancios is isorinio sluoksnio, siluma ir dregme izoliuojanciu bei pamusalo sluoksniu. Atlikus daugiasluoksniams paketams panaudotu tekstiles medziagu ir is ju suformuotu paketu mechaniniu ir fiziniu savybiu tyrimus, nustatyta, kad atskiro sluoksnio medziagos savybes daro tiesiogini poveiki viso paketo apsauginems ir devejimo komforto savybems. Siekiant sukurti lengvesnius apsaugines ugniagesiu aprangos daugiasluoksnius paketus, istirtos strukturos, suformuotos is mazesnio pavirsinio tankio reljefinio pavirsiaus tekstiles medziagu, ir ju savybes palygintos daugiasluoksniu paketu, suformuotu is lygaus pavirsiaus tekstiles medziagu, savybems. Nustatyta, kad daugiasluoksniu paketu strukturos, suformuotos is reljefinio pavirsiaus medziagu, del pavirsiaus nelygumo sukuria papildomus oro tarpus, kurie leidzia uztikrinti analogiskas apsaugines savybes, esant mazesniam paketo pavirsiniam tankiui. Be to, mazesnio svorio sistemos suteikia geresnes devejimo komforto savybes.
