The invention discloses a composite vamp fabric with gradient functions and a preparation method thereof. The composite vamp fabric is composed of a surface fabric and a lining which are superposed successively; the surface fabric is a blended fabric prepared by blending fibers including
polyester fibers, China hemp fibers and cotton fibers; the lining is a stitch-bonded non-
woven fabric comprising a hydrophobic layer I, a hydrophilic layer and a hydrophobic layer II which are superposed successively; and the hydrophobic layer I, the hydrophilic layer and the hydrophobic layer II are all composed of hydrophobic fibers, hydrophilic fibers and hot-melt bonding fibers. The gradient functions refer to that the air permeability, wet permeability, quick-
drying performance, strength and
wear resistance of the composite vamp fabric increase from lining layer to
surface layer of the composite vamp fabric while the hygroscopicity and
antibacterial property of the composite vamp fabric decrease. The composite vamp fabric provided by the invention has good hygroscopicity and quick-
drying performance, is antibacterial and
deodorant, and is comfortable to wear; and the strength of the composite vamp fabric meets needs of wearing, so shoe making cost can be reduced, and shoe quality is improved.
