Description

Technical Field

[0001] The utility model relates to the technical field of denim fabrics, in particular to a knotted double-layer special extra-heavy denim fabric. Background Art

[0002] Traditional denim fabric is a relatively thick and heavy yarn-dyed warp-faced twill cotton fabric, which has the characteristics of tight texture, thickness, bright color, clear weave pattern, etc. Among the existing denim fabrics, the fabric weight is usually about 13.5 ounces, and there are very few thick denim fabrics over 14.5 ounces. Moreover, most denim fabrics are developing towards the direction of lightness, such as the content shown in the patent with the authorization announcement number CN204550921U. In the technical solution disclosed in this patent, although the air permeability of the denim fabric is improved by changing the thickness of the yarns in the denim fabric, the original advantages of the denim fabric such as thickness and durability are abandoned or reduced, making it difficult to meet the requirements of some high-intensity scenarios, such as judo training, mountain climbing, field training, etc. Therefore, a strong and durable knotted double-layer special extra-heavy denim fabric is needed. Summary of the Invention

[0020] The following specific examples illustrate the embodiments of the present utility model. Those skilled in the art can easily understand the other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific embodiments. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0021] It should be noted that the drawings provided in the following embodiments only illustrate the basic concept of the present utility model schematically. Therefore, only the components related to the present utility model are shown in the drawings, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and ratio of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0022] Embodiment 1:

[0023] As Figure 1As shown in the figure, a double - layer special extra - heavy denim fabric includes warp yarn 1 and weft yarn 2; the warp yarn 1 includes surface warp 11 and inner warp 12, and the weft yarn 2 includes surface weft 22 and inner weft 21; the quantity ratio of the surface warp 11 to the inner warp 12 is 1:1, and the quantity ratio of the surface weft 22 to the inner weft 21 is 1:1; the surface warp 11 and the surface weft 22 are interwoven to form the surface layer, and the inner warp 12 and the inner weft 21 are interwoven to form the inner layer; the weaving structure of the surface layer is 7 / 1, and the weaving structure of the inner layer is 2 / 6 + 1 / 7; the count of the surface warp 11 is less than that of the inner warp 12; the count of the surface weft 22 is less than that of the inner weft 21.

[0024] In this example, the surface warp 11 and the inner warp 12 are arranged at intervals, and the surface weft 22 and the inner weft 21 are arranged at intervals; as Figure 1 shown, the first - column yarn is set as the surface warp 11, the second - column yarn is set as the inner warp 12, the third - column yarn is set as the surface warp 11, the fourth - column yarn is set as the inner warp 12, and this pattern circulates accordingly. Similarly, in the horizontal weft yarn 2, it also circulates according to a similar pattern.

[0025] The repeat of the fabric structure of the denim fabric is 8; among them, the repeat of the surface layer is 4, and the repeat of the inner layer is 4.

[0026] The surface layer selects the surface warp 11 with a count of 7 and the surface weft 22 with a count of 10; the inner layer selects the inner warp 12 with a count of 10 and the inner weft 21 with a count of 16. The counts of the surface warp 11 and the surface weft 22 in the surface layer are lower, making the yarns shown in the surface layer thicker, forming a rough style. While the counts of the inner warp 12 and the inner weft 21 in the inner layer are higher, making the yarns shown in the inner layer thinner, delicate inside, and improving the comfort of the fabric against the skin when wearing. In this example, the twist range of the surface warp 11 and the surface weft 22 in the surface layer is 320 - 380; the twist range of the inner warp 12 and the inner weft 21 in the inner layer is 320 - 380; compared with the yarns with a twist range of 370 - 410 in traditional denim fabrics, the low - twist yarns used in this example have a lower twist, the yarns are not tight, more fluffy, more comfortable to wear, and the fiber gaps in the yarns are large, so the air - permeability can also be improved, overcoming the negative impact brought by the double - layer structure to a certain extent. In addition, the low - twist yarns also have the characteristics of good moisture absorption, quickly absorbing the sweat discharged due to high - intensity exercise. The surface warp 11, the inner warp 12, the surface weft 22, and the inner weft 21 all adopt rotor - spun yarns.

[0027] Both the front and back sides of the denim fabric are singed at least once. It should be noted that the singeing process of the fabric uses the existing process; in this example, it includes the singeing processes of one front and two backs and two fronts and one back. Among them, one front and two backs means that the front side of the fabric is singed once, and the back side of the fabric is singed twice, making the back side of the fabric, that is, the side in contact with the skin, smooth and delicate, friendly to the skin, and improving the comfort of the clothing worn close to the skin. Two fronts and one back means that the front side of the fabric is singed twice, and the back side of the fabric is singed once, making the back side of the fabric, that is, the side facing outwards, smooth and not prone to pilling during exercise.

[0028] During the implementation process, by setting the double-layer structure and cooperating with the knitting structures of the surface layer and the inner layer, the denim fabric is obtained with the performance of extra heavy weight to meet the fabric requirements of high-intensity special environments; by setting the yarn counts of the surface layer and the inner layer, the denim fabric forms a rough exterior and delicate interior style; by setting the twist range of the yarns and using low-twist yarns, the air permeability and sweat absorption performance are improved, and the wearing comfort is enhanced.

[0029] The above description is only a specific example of the present utility model and does not constitute any limitation to the present utility model. Obviously, for professionals in this field, after understanding the content and principle of the present utility model, various modifications and changes in form and details may be made without departing from the principle and structure of the present utility model. However, these corrections and changes based on the idea of the present utility model are still within the protection scope of the claims of the present utility model.
