Investigation of End-use Properties of Fabrics From Metaaramid Yarns

Abstract

The investigations of end-use mechanical properties of fabrics from metaaramid yarns as well as of multilayer pocket for fireman clothes is presented in the article. The comparison of end-use properties of various metaaramid fabrics (“Nomex”, “Kermel”, “Conex”), which are used in the world, is presented, too. The investigation of influence of weave on end-use properties (tearing strength, air permeability, surface density) of outer fabric for fireman clothes is carried out. The regressive equations obtained has a satisfactory high determination coefficients and can be used for prognosis of properties of fabrics from “Nomex Delta TA” 18.5 tex × 2 spun yarns and obtaining of optimal weave by various requirements. The using of multilayer pocket with presented lower surface density not only decreased a cost of fireman’s clothes, but also decreased a weight and increased a comfortability of clothes wearing without requirements decreasing. The designed protective fireman’s clothes have been certificated in Sacsony Textile Research Institute.
