The invention discloses a high-strength elastic cloth and a production technique thereof. The high-strength elastic cloth is made from, by weight part, 40-50 parts of acrylic fiber, 7-14 parts of polyether sulfone, 1-3 parts of nano elastomer composite fiber, 2-4 parts of raw bamboo fiber, 1-4 parts of Naomi mineral fiber, 4-10 parts of montmorillonite powder, 2-5 parts of chitin fiber, 3-7 partsof flame-retardant polyester fiber, 3-9 parts of a cellulase solution, and 1-2 parts of titanium dioxide. The production technique is simple; the produced cloth herein has high strength, good elasticity and good flexibility, as well as excellent wear resistance, flame retardance, bacterial resistance and tensile strength, and better hand feeling.
