Identifikacija sintetičkih tekstilnih vlakana probom gorenja

In this paper the identification of textile fibers by burning test was carried out. This method is one of the easiest and fastest preliminary methods that can be used in fiber forensics. The primary objective of this paper is to validate the method of identification of textile fibers by burning test. The intention was to evaluate whether this simple and fast procedure is suitable for use in forensics as a preliminary method of identifying traces of textile fibers. All known synthetic fibres as well as the methods used for the identification of textile fibres are presented and described. Afterword the identification of textile fibres by the burning technique was performed through the experiment. During the first part of the experiment, synthetic fibres were used: polyester fibres, polyamide fibres, aramid fibres, polypropylene fibres, polyethylene fibres, acrylic fibres and fluorinated fibres. In the second part of the experiment firefighters paints Fire ECO Fire Brigade (Art No. 1372 001A1) was used; EN 469 2005 + A1: 200; manufacturer: 2011 TEXPORT GmbH, Salzburg. Part No. 11371. Composite outer material: Nomex Tough of 75% m-Aramid (Nomex), 23% p-Aramid (Kelvar), 2% P140 (Carbon); water-repellent lining of 100% eptfePTFE from Gore-Tex; thermal lining of Runo consisting of 100% m-Aramid (Nomex) and fabrics consisting of 50% m-Aramid (Nomex), 50% Viscosa FR. Using this preliminary method, it has been shown that it is possible to determine which fibre has be used or to which fibre group the sample belongs.
