Abstract:
1. A method of converting textile solid waste into a graphite manufacture, comprising subjecting textile solid waste to a preparing process comprising: washing the textile solid waste; stripping the textile solid waste of non-carbon-containing or non-textile substances; separating the textile solid waste by at least one observable property chosen from color, nature of the fabric, and denier; cutting the textile solid waste; shredding the textile solid waste; filtering the textile solid waste; and micronizing the textile solid waste; and thereafter, subjecting textile solid waste to a graphitization process under a pyrolysis/sintering system and a set of conditions in which sintering is at a temperature 1500 to 3000° C. and in which at least one other conditions is chosen from sintering at a pressure ranging from 1 to 300 bar; sintering at a vacuum ranging from 5×10 sintering while applying, to the textile solid waste, a pressing force 1 to 100,000 kN; and applying, to the textile solid waste, an electrical current having a power ranging from 1 to 2000 kW per pulse.
