Abstract

Sastavno gledano vojna odora je materijal na bazi tkanine, dakle celuloze i poliamidnih vlakana. Osnovna svojstva koja ima svaka odora se postižu kombinacijama sastava. Uz njih moguće je postići i dodatna napredna svojstva koje nije moguće postići osnovnim modifikacijama materijala koji se prede, već korištenjem premaza i sličnih dodataka. Tako se mogu ostvariti funkcionalna svojstva moderne odore. Međutim zadržavanje tih svojstava nije lako s obzirom na snažna mehanička opterećenja kojima je... More oprema izložena zbog korištenja i održavanja. Posebno higijensko održavanje može biti nepovoljno u smislu zadržavanja funkcionalnih premaza i ključnih svojstava. U ovom radu ispitana su funkcionalna svojstva prikrivne odore Oružanih snaga Republike Hrvatske korištenjem naprednih termičkih, spektroskopskih i optičkih metoda. Ispitan je utjecaj kvalitete i funkcionalnosti materijala od kojih je sastavljena vojna odora. Uspoređivao se novi materijal i onaj koji je podvrgnut simuliranom starenju u obliku izlaganja vlažnim uvjetima i povišenoj temperaturi. Različiti tipovi uniforme doista iskazuju funkcionalne kvalitete u pogledu izdržljivosti na habanje. Međutim premazi pokazuju izrazitu sklonost starenju. Naime, ključni doprinos starenju uzoraka je sadržan u uklanjanju aktivnih premaza zbog mehaničkih opterećenja. Iz toga proizlazi zaključak kako je izrazito bitno naglasiti nužnost ispravnog i odgovornog korištenja odore, te primjerenog održavanja iste kako bi se aktivni premazi održali što je duže moguće.

Abstract (english)

A military uniform is a material based on textile, which translates to cellulose. The basic properties that each uniform possesses are achieved through combinations of differing base materials. It is also possible to achieve additional advanced properties through the utilisation of different coatings which are applied to the basic uniform. Those properties can be hardly achieved through the processing of the basic fabrics. Keeping the mentioned properties is demanding due to harsh conditions... More military uniforms go through during exploitation and maintenance. Special hygienic maintenance can have an adverse effect on preserving the functional coatings and crucial properties. This master's thesis revolves around testing the functional properties of the camouflage uniform currently utilised by the Croatian Armed Forces. Advanced thermal, spectroscopic and optic methods are used to analyse the material from which the uniform is comprised. A comparison was made between a completely new sample and one which has been aged through the simulation of wet and hot environments. The two samples show how the uniform keeps its functional properties. The uniform shows substantial degradation of properties through the aging process. The active coating is heavily compromised by sustained exploitation and maintenance, mainly due to physical strain the uniform goes through daily. This testing shows how important proper and responsible usage of the uniform actually is, and why it is crucial to properly maintain it in order to preserve those coatings and properties. Less
