The invention discloses a biomass camellia fiber spunlace material and a preparation method thereof. The biomass camellia flower fiber spunlaced material comprises regenerated cellulose viscose, wherein camellia oil extracted from camellia seeds is mixed in the regenerated cellulose viscose, the camellia oil is kneaded into wood pulp, and a spunlace technology is used for manufacturing the spunlace new material with meshes; the preparation method comprises the following steps: (1) preparing raw materials; (2) conveying opened camellia fiber raw materials into two carding machines respectively, carding the fibers into a uniform fiber web through the first carding machine, carding the conveyed fibers into a uniform fiber web through the second carding machine, then overlapping with the fiber web carded by the first carding machine, and conveying the two fiber webs together into a spunlace machine for reinforcing; (3) conveying the fiber webs into a spunlace system to carry out six spunlace procedures to realize high-pressure hydro-acupuncture front-back piercing reinforcing; (4) conveying into a dryer for drying; (5) winding, slitting and packaging.
