A fluorine-free carbon chain hydrophobic fabric, and its preparation method and application. A fabric is sequentially soaked in an alkali liquor and an acid liquor to obtain a pretreated fabric; the pretreated fabric then reacts with bromoacetyl bromide to obtain a treated fabric; the treated fabric then reacts with 1,2-bis(p-toluenesulfonyl) hydrazine to obtain a diazotized fabric; the diazotized fabric reacts with a diazoacetate monomer to obtain a fluorine-free carbon chain hydrophobic fabric; and the diazoacetate monomer is butyl diazoacetate, hexyl diazoacetate, octyl diazoacetate, dodecyl diazoacetate, tetradecyl diazoacetate or octadecyl diazoacetate. According to the scheme, diazoacetate is used as a monomer, and different fiber grafting modification processes are used, so as to form different structures on the fiber surface; and the comprehensive properties such as thermal stability, air permeability and breaking strength of the finished fabric are tested, the heat resistance and breaking strength of the finished fabric are reduced, and the air permeability is good.
