[0013] Figure 2 Cross-sectional view of the denim fabric of the present utility model. Specific implementation manner

[0014] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0015] Combined with the embodiments and the attached Figure 1-2 , a super-high elastic denim fabric, including a denim layer, the denim layer includes a shape-retaining layer 1, a cotton base layer 2 and a functional layer 3. The shape-retaining layer 1 includes interwoven weft yarns and elastic warp yarns. The weft yarns include a first weft yarn and a second weft yarn. The first weft yarn is a wear-resistant weft yarn, and the second weft yarn is an elastic weft yarn; the shape-retaining layer 1 is connected to the cotton base layer 2 on the inner side, and the cotton base layer 2 is connected to the functional layer 3 on the inner side. The functional layer 3 is woven and formed by moisture-absorbing and sweat-discharging fibers.

[0016] The cotton base layer 2 is knitted to form a number of breathable holes 20 arranged in a honeycomb shape. The aperture of the breathable holes 20 is 1-3 cm. The total area of the breathable holes 20 accounts for 55%-80% of the total area of the cotton base layer 2, so that the cotton base layer 2 constitutes a honeycomb-shaped skeleton, providing support and deformation functions for the shape-retaining layer and the functional layer.

[0017] Furthermore, the cotton base layer 2 further includes a first sewing thread 201 for connecting the shape-retaining layer 1 and a second sewing thread 202 for connecting the functional layer 3. The first sewing thread 201 is interwoven with the wear-resistant weft yarn to assist in providing a lasting shape-retaining function. The second sewing thread 202 is interwoven with the moisture-absorbing and sweat-discharging fibers.

[0018] Both the elastic warp yarn and the elastic weft yarn are made of spandex and T400 double-core core-spun yarn.

[0019] The wear-resistant weft yarn is woven from Cordura nylon filaments. The proportion of the wear-resistant weft yarn in the weft yarn in one tissue cycle of the shape-retaining layer 1 is not less than 20%, so that the denim fabric has wear resistance and shape-retaining effects while retaining high elastic stretching. Among them, the wear-resistant weft yarn is connected to the honeycomb layer skeleton of the base layer, playing a role of restraining and shaping the elastic warp yarn and the elastic weft yarn.

[0020] Furthermore, the order of the weft yarns in one tissue cycle of the shape-retaining layer is the first weft yarn - the second weft yarn - the first weft yarn - the first weft yarn or the first weft yarn - the second weft yarn - the second weft yarn - the first weft yarn.

[0021] The moisture-absorbing and sweat-evaporating fiber is a cotton fiber with a special-shaped cross-section, and the moisture-absorbing and sweat-evaporating fiber can be selected from cotton fibers with Y-shaped, O-shaped, and cross-shaped cross-sections. The honeycomb-shaped framework is assisted by the cotton fiber with a special-shaped cross-section to realize the breathable and sweat-evaporating function on the inner side of the ultra-high elastic denim fabric.

[0022] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
