Abstract (en)
The present invention relates to a method for manufacturing a multiple-use nonwoven fabric structure having an Arc Thermal Protection Value (ATPV) to fabric basis weight ratio greater than 500 cal/g and being a Hazard Risk Category 2 in accordance with NFPA 70E Standard for Electrical Safety in the Workplace. The method comprises the steps of providing a web of inherently fire-resistant fibers, bonding the fibers of the web by means of needle-punching to form a nonwoven fabric layer, and bonding the nonwoven fabric layer by means of spunlacing to form the non-woven fabric structure.
