A hemostatic textile comprising glass fibers circular knit with bamboo-sourced rayon fibers in a tubular fashion. The knitted textile is scoured and dried to shrink the bamboo-sourced rayon relative to the glass fibers and to orient the glass fibers exteriorly of the bamboo-sourced rayon fibers such that when the hemostatic textile is administered to a wound, the glass fibers are the first to come in contact with any wound fluid, for example blood. This orientation aids in the activation of the hemostatic response which leads to faster clot times and improved overall wound-healing. A method of manufacturing and utilizing the hemostatic textile is also provided.
