摘要

The present invention relates to an arc flash protection, multiple-use nonwoven fabric structure comprising one or more layers having fire resistant properties. The fabric structure has an arc flash facing nonwoven surface. Furthermore, the fabric structure has a minimum Arc Thermal Protection Value (ATPV) to fabric basis weight ratio of 250 cal/g, when measured in accordance with ASTM F1959 - Standard Test Method for Determining the Arc Rating of Materials for Clothing, and the fabric structure maintains said ATPV to fabric basis weight ratio through at least 25 washing cycles, when washed according to AATCC Method 135 (3,IV, A iii).
