Abstract

Vpliv dodanih vlaken MAC in MTF v mešanici na mehanske lastnosti prstanske preje za varovalne tekstilije

Highlights

The research is focused on the influence of the fire resistant modacrylic (MAC) fibres in the ring-spun yarn mixture with cotton (CO) fibres and of the conductive metal fibres (MTF) in the ring-spun yarn mixture with polyester (PES) fibres on the mechanical properties in the region of lower loads
The incorporation of MTF fibres in the yarn mixture consisting of 75% PES/25% MTF decreases the region of elastic deformations, the region of elastic deformations lies very close to the chosen stress value under the specific stress/extension curve – 5 cN/tex or 85 g
Since the yarns analysed are intended for the protective clothing production, the research focuses on the mechanical behavior of the yarns analysed. e research focuses on the eld of lower loads under the speci c stress/extension curve which amounts to 5 cN/tex, wherein the stress presents the weight of around 85 g

Summary

Introduction

The research is focused on the influence of the fire resistant modacrylic (MAC) fibres in the ring-spun yarn mixture with cotton (CO) fibres and of the conductive metal fibres (MTF) in the ring-spun yarn mixture with polyester (PES) fibres on the mechanical properties in the region of lower loads. Analysed yarns are intended for the protective clothing production (fire resistant and electrically conductive clothing). Vsebnost MTF (iz nerjavnega jekla) vlaken v mešanici iz 75 % PES in 25 % MTF vlaken vpliva na zmanjšanje elastičnega območja za okrog 10 %, na drugi strani pa se vrednosti elastičnega območja gibljejo v mejah območja manjših (uporabnih) obremenitev na krivulji specifična napetost/raztezek, ki znaša 5 cN/tex oziroma 85 g. E facts presented above have encouraged the direction of the research in regard to the mechanical behavior of the ring-spun yarn from ame resistant and electrically conductive yarn mixtures. Many researchers are interested in electrical and conductive properties of bres and fabrics intended for protective clothing [4,5,6,7]. A growing segment of the industrial textiles industry has been involved in a number of new developments in bres, fabrics and protective clothing. There are additional requirements, such as protection against heat by providing insulation, as well as high dimensional stability of the fabrics, so that, upon exposure to the heat uxes that are expected during the course of the wearer’s work, they will neither shrink nor melt [1, 2]
