The invention discloses a low-temperature hot melt adhesive composite sheet containing fibrilia. A preparation method of the low-temperature hot melt adhesive composite sheet comprises the following steps: (1) crushing fibrilia or fibrilia yarn powder into fibrilia short fibers with the particle size of 0.1-1mm; (2) uniformly mixing hemp short fibers and hot melt adhesive particles according to a mass ratio of (30-70): (70-30), and carrying out hot press molding at 80-120 DEG C to form a middle base material layer with the thickness of 0.5-3mm; (3) coating a low-temperature hot melt adhesive layer on each of the upper surface and the lower surface of the middle base material layer; the melting point of the low-temperature hot melt adhesive layer is 60-100 DEG C, and the thickness of a single layer is 0.05-0.5 mm. According to the low-temperature hot melt adhesive composite sheet containing the jute fibers, the jute fibers are used in the middle base material layer, so that the low-temperature hot melt adhesive composite sheet has the antibacterial, mildew-proof and moisture-absorbing effects of the jute fibers, and can be applied to the fields of furniture, wallboards, automotive interiors, shoe materials and the like.
