Warp-knitted shoe material fabric with three-proofing function and preparation method of warp-knitted shoe material fabric

The invention relates to the field of shoe material fabrics, provides a three-proofing functional warp-knitted shoe material fabric and a preparation method thereof, and solves the defects that waterproof, oil-proof and antifouling fabrics in the prior art are poor in air permeability, have no double-color effect on a surface layer and are not clear in concave-convex feeling. Comprising the following steps: 1) selecting raw material yarns; (2) dyeing; (3) knitting: knitting the dyed raw material yarns by using a double-jacquard warp knitting machine; and 4) shaping: enabling hot air to uniformly act on the front and back surfaces of the fabric at 200 DEG C, and performing tentering shaping, coloring, inspection, packaging, warehousing and other processes to obtain the three-proofing functional warp-knitted shoe material fabric. 本发明涉及鞋材面料领域，提供一种三防功能经编鞋材面料及其制备方法，解决现有技术的防水防油防污面料透气性差、表面层无双色效应、面料凹凸感不分明的缺陷；包括如下步骤：1)原料纱的选择；2)染色3)编织：选用双贾卡经编机对染色后的原料纱进行编织；4)定型:200℃下使热空气均匀的作用于面料的正反两面，并经过拉幅定型、批色、检验、包装入库等过程，获得三防功能经编鞋材面料。
