The invention discloses a double-side single-made preparation method of double-layer fabric clothes, which comprises a splicing method, namely sewing a seam
cutting positioning line at the position close to the edge of the cloth of a double-layer
cut-part fabric; splitting along the
cutting seam positioning line to obtain a
surface layer and an inner layer; trimming off the split part of the lining fabric along the slitting positioning line; removing the seam
cutting positioning line; adhering an
adhesive lining strip to the reverse inner side of the
surface layer with the inner layer
cut off for reinforcement; oppositely overlapping the surface
layers of the two pieces of
cut fabric, aligning the edges of the
