However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. It should be understood that the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0032] In the description of the present utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0033] The weight of the relevant components mentioned in the specification of the embodiments of the present invention can not only refer to the specific content of each component, but also indicate the weight ratio between the components. Therefore, as long as the content of the relevant components is proportionally enlarged or reduced according to the specification of the embodiments of the present invention, it is within the scope disclosed in the specification of the embodiments of the present invention. Specifically, the weight described in the specification of the embodiments of the present invention can be a mass unit known in the chemical industry such as μg, mg, g, kg, etc.

[0034] In the present application, the weave cycle refers to the situation where the warp and weft weave points in the fabric rise and fall in a cycle.

[0035] Twill weave can be divided into weft twill weave and warp twill weave, in which the number of weft weave points in weft twill weave is greater than the number of warp weave points, and the number of warp weave points in warp twill weave is greater than the number of weft weave points.

[0036] Layering point: In double-layer weaving, all the surface warp yarns must be lifted when weaving the inner weft yarn. In the squares where the surface warp and the inner weft are interwoven in the fabric structure diagram, unique warp organization points must be added to all of them. They are represented by a special symbol ○ and are called layering points.

[0037] An embodiment of the present application provides a knitted denim fabric, comprising a surface layer, a connecting layer and an inner layer; the surface layer comprises surface warp yarns and surface weft yarns woven together, and the structural organization of the surface layer comprises a twill organization; the inner layer comprises inner warp yarns and inner weft yarns woven together, and the structural organization of the inner layer comprises a weft satin organization, and 7 to 15 weft organization points are arranged between two adjacent warp organization points on each warp yarn in the weft satin organization; the connecting layer comprises inner warp yarns and surface weft yarns woven together, and the connecting layer connects the surface layer and the inner layer through the inner warp yarns and the surface weft yarns woven together.

[0038] The imitation knit denim fabric has a surface layer, a connecting layer and an inner layer, wherein the connecting layer connects the surface layer and the inner layer by interweaving the inner warp yarn and the surface weft yarn, and the surface layer includes a twill weave, and the inner layer includes a weft satin weave, and a specific number of weft weave points are set between two adjacent warp weave points on each inner warp yarn in the weft satin weave of the inner layer, so as to prevent the number of weft weave points from being too small, the warp float length from being too short, and the coil effect from being lost, and the hand feeling from being not soft, and at the same time, to prevent the number of weft weave points from being too large, resulting in the warp float length being too long, and the weave structure being too loose. The twill weave design of the surface layer makes the front of the imitation knitted denim fabric present the style of traditional denim fabric, and the twill texture is clear; the weft satin weave of the inner layer and the warp weave points and the weft weave points on the inner warp yarn make the warp float length of the inner layer have the coil effect of warp knitted fabric, making the fabric soft, fluffy and thick.

[0039] In the above-mentioned weft satin weave, 7 to 15 weft weave points are arranged between two adjacent warp weave points on each warp yarn. It can be understood that the number of weft weave points arranged between two adjacent warp weave points can be 7, 8, 10, 11, 12, 13, 14 or 15.

[0044] In some embodiments, in each weave cycle of the connecting layer, there is only one warp weave point on each inner warp yarn or each outer weft yarn, and the rest are weft weave points. By controlling the number of warp weave points on each warp yarn or weft yarn in each weave cycle of the connecting layer, not only can the inner layer and the outer layer be connected, but also the influence of the connecting layer on the structure of the outer layer can be reduced.

[0045] In some embodiments, the structural weave of the surface layer includes at least one of a 3 / 1 right twill weave, a 4 / 1 right twill weave, and a 4 / 2 right twill weave.
