Description

Technical Field

[0001] The utility model relates to the field of denim fabrics, in particular to a four-sided stretch imitation knitted denim fabric. Background Art

[0002] Currently, the imitation knitted denim fabrics on the market are basically elastic in the weft direction, but still have the non-elastic properties of traditional denim fabrics in the warp direction. Although the base style of this type of denim fabric is similar to that of traditional knitted fabrics, there is still a slight difference in the feel.

[0003] In order to fill the market gap of imitation knitted denim with elasticity in the warp direction, denim fabrics are woven with elastic yarn to make them have four-way stretch properties, such as the content shown in the patent with the authorization announcement number CN110184711B. However, in this patent solution, since the weft yarn structure is double-layered, the surface of the final fabric will have a wrinkle-like texture, and the surface is not smooth enough, which affects the comfort of wearing. Therefore, a four-way stretch imitation knitted denim fabric with a smooth surface and comfortable wearing is needed. Summary of the invention

[0004] The utility model aims to solve the deficiencies of the prior art and provide a four-sided stretch imitation knitted denim fabric.

[0005] In order to solve the above problems, the utility model adopts the following solutions:

[0006] A four-way stretch imitation knitted denim fabric comprises warp yarns and weft yarns, wherein the warp yarns are pre-shrunk yarns; the weft yarns are pre-shrunk yarns; and the warp yarns and the weft yarns are arranged in a twill according to a double-warp and double-weft variation structure.

[0007] Furthermore, the warp yarns and weft yarns are arranged in a 6 / 1+1 / 1 changing twill.

[0008] Furthermore, the materials used for the two warp yarns in the double-warp and double-weft structure are inconsistent.

[0009] Furthermore, one of the two warp yarns, A, is siro-spun 16-count cotton yarn with a twist coefficient ranging from 370 to 400 and a single yarn strength greater than 15.5 cN / Tex, and the other warp yarn B is 75 / 20D network yarn.

[0010] Furthermore, the materials used for the two weft yarns in the double-warp and double-weft structure are inconsistent.

[0011] Furthermore, one of the two wefts, a weft yarn A, is made of siro-spun 21-count cotton yarn with a twist coefficient of 370-400 and a single yarn strength of ≥15.5 cN / Tex, and the other weft yarn B is made of 100 / 40D network yarn.

[0012] The beneficial effects of the utility model are:

[0013] By setting up a double-warp and double-weft yarn structure, and both the warp and weft yarns are pre-shrunk yarns, on the one hand, the surface of the fabric is kept flat, and on the other hand, the fabric can also have the physical property of four-sided elasticity;

[0014] By using pre-shrunk yarn, the obtained fabric has better anti-shrinkage performance and a certain elasticity. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0018] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and the figures only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0019] Embodiment 1:

[0020] like Figure 1 As shown, a four-way stretch imitation knitted denim fabric comprises a warp yarn 1 and a weft yarn 2, wherein the warp yarn 1 and the weft yarn 2 are pre-shrunk yarns. It should be noted that the pre-shrunk treatment of the yarn is mainly carried out by a pre-shrunk machine, and the existing pre-shrunk treatment method is adopted, and the pre-shrunk treatment is a post-treatment, that is, the pre-shrunk treatment is carried out after the denim fabric is woven, and the pre-shrunk post-treatment is also a conventional method in the field; the warp yarn 1 and the weft yarn 2 are arranged in a twill according to a double warp and double weft variation organization; wherein the double warp and double weft arrangement means that one warp yarn 1 and two weft yarns 2 are interwoven, and at the same time, one weft yarn 2 is also interwoven with two warp yarns 1 to form a twill organization.

[0021] The warp yarn 1 and the weft yarn 2 are arranged in a 6 / 1+1 / 1 variable twill weave. It should be noted that the twill weave in this example is the warp weave, which means that the number of warp weave points is greater than the number of weft weave points. The number of weave cycles of the variable twill is 20.

[0022] The materials used for the two warp yarns in the double-warp and double-weft structure are consistent or inconsistent; in this example, one of the two warp yarns, A, is siro-spun 16-count cotton yarn with a twist coefficient ranging from 370 to 400 and a single yarn strength greater than or equal to 15.5 cN / Tex, and the other warp yarn B is made of 75 / 20D network yarn; in some other embodiments, the warp yarn B can also be made of polyester filament coated with Lycra.

[0023] The materials used for the two weft yarns in the double-warp and double-weft structure are consistent or inconsistent; in this example, one of the two weft yarns A is made of siro-spun 21-s cotton yarn with a twist coefficient of 370-400 and a single yarn strength ≥15.5cN / Tex, and the other weft yarn B is made of 100 / 40D network yarn.

[0024] The pre-shrinking treatment can make the warp and weft yarns 2 shrink to the maximum extent in the warp and weft directions before washing, avoid shrinkage in washing, ensure dimensional stability, and allow the yarn to have a certain elasticity in the warp and weft directions. It should be noted that since both the warp and weft directions need to be pre-shrinked, it is necessary to pre-shrink in the two directions separately, that is, the existing double shrinking process. In order to achieve the final elastic pre-shrinking effect, multiple pre-shrinking in one direction can also be performed, especially in the weft direction.

[0025] The denim fabric is woven on a double-beam loom, in this case a Picanol double-beam OPT loom; polyester filament coated Lycra covered yarn is arranged on the zenithal of the double-beam loom as warp yarn 1, and the tension of a single warp yarn 1 is controlled by a slitting warping machine to ensure that the tension of all warp yarns 1 on the zenithal is consistent, while weft yarn 2 is arranged on the ground axis.

[0026] During the implementation process, by setting a double warp and double weft yarn structure, and both the warp yarn 1 and the weft yarn 2 are pre-shrunk yarns, on the one hand, the surface of the fabric is kept smooth, and on the other hand, the fabric can have four-sided elastic physical properties without using elastic yarns; by using pre-shrunk yarns, the obtained fabric has better anti-shrinkage performance.

[0027] The above description is only a specific example of the utility model and does not constitute any limitation to the utility model. Obviously, for professionals in this field, after understanding the content and principle of the utility model, it is possible to make various modifications and changes in form and details without departing from the principle and structure of the utility model, but these modifications and changes based on the idea of ​​the utility model are still within the scope of protection of the claims of the utility model.
