The invention relates to a gummed flocking type high-elastic antibacterial warmth keeping flaky material and a manufacturing method thereof, belonging to the field of textile technology. An antibacterial agent is sprayed inside the upper-layer fiber web and lower-layer fiber web of the high-elastic antibacterial warmth keeping flaky material, the opposite surfaces of the upper-layer fiber web and lower-layer fiber web are coated with upper binding agent film and lower binding agent film, fluff is clamped between the upper-layer fiber web and the lower-layer fiber web, and two ends of the fluff are inserted into the upper binding agent film and the lower binding agent film respectively, and are solidified on the surfaces of the upper-layer fiber web and the lower-layer fiber web. The manufacturing method thereof comprises the following steps: (1) fiber web preparation, (2) antibacterial agent spraying, (3) drying, (4) gumming, (5) electrostatic flocking, (6) drying, (7) fluff absorption, (8) fiber web recombination, (9) drying, and (10) winding. Compared with the prior art, the warmth keeping flaky material manufactured by the invention has an antibacterial function, good elasticity and good warmth keeping performance.
