Abstract:V prispevku sta predstavljena dva različna načina nateznega preizkušanja linijskih tekstilij: natezno preizkušanje pri standardnih pogojih preizkušanja s standardnim dinamometrom in natezno preizkušanje pri ve- likih hitrostih. Raziskovali smo obnašanje treh tipov tehničnih filamentnih prej: dveh poliamidnih (PA 6.6 in PA 4.6) in polietilenteraftalatnega (PET) multifilamenta visokih trdnosti. Na podlagi rezultatov raziskave sklepamo, da deformacijska hitrost ($\dot{\epsilon}$) pri vseh treh preizkuševalnih prejah vpliva na natezne lastnosti materiala. To pomeni, da se mehanskih lastnosti in nateznega obnašanja prej pri velikih hitrostih obremenitve ne da pojasnjevati zgolj s podatki, dobljenimi pri standardnih pogojih preizkušanja, temveč je treba uvesti ustrezno metodo z višjimi hitrostmi preizkušanja.

Title:Influence analysis of test speed on technical filament yarns behaviour in tensile test
Abstract:Two different ways of tensile testing of liner textiles, namely the tensile testing under standard conditions with a standard dynamometer and high-speed tensile testing are presented in the article. Within this research, we studied the behaviour of three types of high-tenacity multifilament technical filament yarns, i.e. two polyamide yarns (PA 6.6 and PA 4.6) and polyethylene terephthalate (PET). Based on the results of the research, we can conclude that the strain rate ($\dot{\epsilon}$) in all three tested yarns affected the material tensile properties. This means that the mechanical properties and tensile behaviour of technical yarns cannot be explained only with the data obtained under standard test conditions. For better understanding of the behaviour of technical yarns, it is necessary to introduce an appropriate method with high-speed testing
Keywords:technical multifilament yarns, conventional tensile test, high speed tensile test, standard tensile testing machine, servo-hydraulic tensile testing machine
