Inorganic Yarn from Volcanic Rock Melt

Solution Overview

Problem

Conventional organic yarns deteriorate at high temperatures and have limited strength, while existing inorganic fibers require expensive processing and transportation due to the use of mineral powders, necessitating a more cost-effective and efficient method for manufacturing high-strength, heat-resistant yarns.

Innovation Solution

A system and method using unrefined volcanic rock mixed with additives like potassium permanganate, processed in a cupola furnace to form a melt, which is then extruded into filaments, cooled, sized, and twisted into inorganic yarns with enhanced strength and heat resistance.
