This application relates to the field of textile fabrics, disclosing a three-dimensional anti-permeability fabric and its preparation process. The three-dimensional anti-permeability fabric includes a first woven layer and several second woven layers. The second woven layers are formed by weaving core-spun yarn onto the first woven layer using a weaving process. The edges of the second woven layers are formed by cutting and high-temperature setting of the core-spun yarn to create a three-dimensional plush structure. The core yarn of the core-spun yarn is made by twisting several high-melting-point yarns and at least one glass fiber yarn together, while the covering yarn is a low-melting-point yarn. The three-dimensional anti-permeability fabric obtained by this application, after cutting and high-temperature setting of the core-spun yarn at the edges of the second woven layers, shrinks the core-spun yarn to form a spiral shape, creating a three-dimensional plush structure at the edges of the second woven layer. Under the synergistic support of the core yarn and the shrunk covering yarn, a stable three-dimensional anti-permeability fabric is formed. It is not easily deformed during long-term wear and washing, maintaining good softness, three-dimensionality, and anti-permeability.
