Influence of Woven Fabrics Structure upon Flammability Properties

Abstract

Fabrics flammability depends on various factors such raw material of fiber, its linear density, thread density, fabric construction, oxygen and humidity concentration in the environment, even on the weave type of fabric. In this presentation the influence of woven fabric’s thread density and weave type upon flammability properties were investigated. Fabric woven from the metaaramid Nomex Delta TA 18.5 tex × 2 spun yarns were used for investigations. The flammability properties of all tested fabrics are determined using Burning Cabinet Type BKD for standard horizontal flammability test methods due to theirs similarity to fabric real flammability behavior. It has been found that fabric structure influenced on fabric hole burning time – the hole burning time increases if density of yarns or weave factor P1 increases, too.
