Description

Technical Field

[0001] This utility model relates to the field of textile technology, specifically to a denim-like fabric. Background Technology

[0002] Denim is a classic clothing fabric, and its versatility, ease of wearing and care has always made it a favorite among the market and consumers.

[0003] Traditional denim fabrics are mostly woven fabrics, typically using blue warp yarns and white weft yarns interwoven in a twill weave. Due to its woven structure, traditional denim fabrics generally suffer from poor softness, a stiff feel, a lack of body fit, poor breathability, and poor stretch. In particular, its woven structure gives the fabric very low stretch elasticity, restricting the freedom of movement and thus affecting wearing comfort.

[0004] In addition, the traditional denim fabric weaving process is lengthy and complex, usually requiring a series of steps such as "winding → warping → sizing → threading the reed → weaving → washing → finishing". This results in low production efficiency. At the same time, the lengthy and complex process consumes a lot of energy, which in turn leads to the high price of the finished product. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides a denim-like fabric. On the one hand, it can improve the fabric's stretch resilience, breathability, and softness, thereby increasing the freedom of movement and wearing comfort. At the same time, it can form natural three-dimensional textures on the surface of the fabric, giving it a sense of layering and a high degree of denim simulation. On the other hand, it can simplify the production process, reduce production costs, and improve production efficiency.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A denim-like fabric includes colored yarn, periodic thick yarn, and elastic yarn. The thickness of the periodic thick yarn varies periodically. The colored yarn, the periodic thick yarn, and the elastic yarn are knitted into a single-sided jacquard structure with a three-way repeat. The colored yarn is fed in the first way, the periodic thick yarn is fed in the second way, and the elastic yarn is fed in the third way. A complete structure of the single-sided jacquard structure covers three wale loops.

[0008] As a further improvement to the above technical solution, the first loop warp is formed by the colored yarn alone, and the second and third loop warps are formed by feeding the periodic thick yarn and the elastic yarn together and forming them together.

[0009] As a further improvement to the above technical solution, when forming the second and third coils, the coarse segments of the periodic coarse yarn participate in the loop formation in a non-predictable manner, resulting in a non-uniformly distributed raised granular texture on the fabric surface.

[0010] As a further improvement to the above technical solution, the single-sided jacquard weave forms a diagonal pattern on its front side.

[0011] As a further improvement to the above technical solution, the colored yarn is blue, and the periodic thicker yarn is white.

[0012] As a further improvement to the above technical solution, the colored yarn is pure cotton compact Siro yarn with a count of 16s-20s and a twist direction of Z twist.

[0013] As a further improvement to the above technical solution, the periodic coarse yarn is a pure cotton compact yarn with a count of 30s-40s and a twist direction of Z.

[0014] As a further improvement to the above technical solution, the elastic yarn is spandex with a fineness of 50D-60D.

[0015] As a further improvement to the above technical solution, the cotton content of the fabric is 95%-97%.

[0016] As a further improvement to the above technical solution, the fabric weight is 285-315 g / m². 2 .

[0017] The beneficial effects of this utility model are:

[0018] 1. This utility model provides a denim-like fabric. By adding elastic yarn, the denim-like fabric has excellent stretch resilience, allowing the fabric to stretch significantly and improving the freedom of movement of the human body. At the same time, the knitted structure is softer than the woven structure, and the single-sided jacquard structure makes the inner lining of the fabric soft. The front side has a pattern, and there are more pores in the knitted structure, making the fabric more breathable, thereby improving the comfort of wearing.

[0019] 2. This utility model provides a denim-like fabric. By adopting a three-way single-sided jacquard weave, the production process is greatly simplified. It eliminates the complex processes of warping, sizing, heddle threading, and reed threading in the traditional denim weaving process, thereby reducing production costs and improving production efficiency.

[0020] 3. This utility model provides a denim-like fabric, which uses periodic variations in the thickness of the yarn to create a natural three-dimensional texture on the surface of the fabric, giving it a sense of layering and a high degree of denim fabric simulation. Attached Figure Description

[0026] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0027] Reference Figures 1 to 3 This utility model provides an example of a denim-like fabric, comprising a colored yarn 1, a periodic thick yarn 2, and an elastic yarn 3. The thickness of the periodic thick yarn 2 varies periodically. The colored yarn 1, the periodic thick yarn 2, and the elastic yarn 3 are knitted into a single-sided jacquard structure with a three-way repeat. The first way is fed with the colored yarn 1, the second way is fed with the periodic thick yarn 2, and the third way is fed with the elastic yarn 3. A complete single-sided jacquard structure covers three loop warp rows.

[0028] Understandably, by adding elastic yarn 3, the imitation denim fabric has excellent stretch resilience, allowing the fabric to stretch significantly and improving the freedom of movement for the human body. At the same time, the knitted structure is softer than the woven structure, and the single-sided jacquard weave makes the inner lining of the fabric soft. Its front side has a pattern, and the knitted structure has more pores, making the fabric more breathable, thereby improving the comfort of wearing it.

[0029] By using a circular knitting machine for one-time forming and employing a single-sided jacquard weave with three-way circulation, the production process is greatly simplified. This eliminates the complex processes of warping, sizing, heddle threading, and reed threading in traditional denim weaving, thereby reducing production costs and improving production efficiency.

[0030] In addition, the periodic variation in the thickness of the yarn 2 creates a natural three-dimensional texture on the fabric surface, giving the fabric a sense of layering and a high degree of denim fabric simulation.

[0031] It should be noted that, in order to produce periodically thicker yarns, a regularly arranged diamond-shaped concave structure is set on the surface of the upper apron in the drafting zone of the spinning machine. When the upper apron rotates periodically within the drafting zone, the diamond-shaped concave surfaces on its surface periodically move to key positions that contact the fiber bundle. When the concave areas begin to contact the fiber bundle, the gripping and control force of the upper apron on the fiber gradually weakens; as the machine rotates, the control force on the fiber reaches its weakest point when the center of the concave surface passes through; subsequently, as the concave area gradually moves away, the control force gradually returns to normal levels.

[0032] Therefore, the periodic changes in control force, which first weaken and then recover, directly cause a regular change in the speed-changing point of the fiber within the drafting zone. During the weaker control phase, more fibers momentarily aggregate at this point, failing to be fully drafted, thus forming a segment that is thinner at both ends and thicker in the middle. As the upper apron continues to rotate, this periodic change in control force repeats itself, ultimately forming a stable, regularly spaced, periodically thick segment structure on the yarn.

[0033] In some preferred embodiments, the first loop warp is formed by the colored yarn 1 alone, and the second and third loop warps are formed by feeding together periodic thick yarn 2 and elastic yarn 3 and forming them together. This ensures that the elastic yarn 3 can be woven evenly and firmly into the fabric structure, avoiding structural distortion or curling caused by excessive differences in the properties of different yarns, and making the fabric elasticity and shape more stable.

[0034] In some preferred embodiments, when forming the second and third loop warps, the coarse segments of the periodic coarse yarn 2 participate in loop formation in a non-predictable manner, resulting in a non-uniformly distributed raised granular texture on the fabric surface.

[0035] Understandably, during the weaving process, because the distribution period of the coarse segments of the periodic thick yarn 2 is difficult to precisely synchronize with the loop-forming action of the knitting needles, the coarse segments of the periodic thick yarn 2 will participate in loop formation in a non-predictable and naturally random manner. The coarse segments of the periodic thick yarn 2 have a larger diameter and a looser structure, which can form a raised and full loop when they participate in loop formation. Conversely, the fine segments of the periodic thick yarn 2 have a smaller diameter and a tighter structure, which can form a relatively flat and compact loop when they participate in loop formation. Therefore, an unevenly distributed, slightly different size and spacing of raised granular texture can be presented on the fabric surface, creating a microscopic uneven structure on the fabric surface. This enhances the texture and layering of the fabric surface, achieving a highly realistic denim appearance.

[0036] In some preferred embodiments, the colored yarn 1 is blue, the periodic thick yarn 2 is white, and further, the single-sided jacquard weave forms a twill pattern on its front side, specifically, the pattern is a 2 / 1 or 3 / 1 right twill.

[0037] The blue yarn 1 provides the most classic blue main color of denim fabric, while the white periodic thick yarn 2 creates a dotted white effect, thus creating a classic blue and white twill pattern on the fabric in regular circles, making the fabric look closer to traditional denim.

[0038] In some preferred embodiments, the fabric contains 95%-97% cotton. Cotton fibers have excellent moisture absorption, breathability, and softness, thereby improving the fabric's moisture absorption, breathability, and skin-friendly properties, ensuring wearing comfort.

[0039] Specifically, yarn 1 is a pure cotton compact Siro-spun yarn with a count of 16s-20s and a twist direction of Z.

[0040] It is understandable that the evenness, smoothness, low surface fuzz, and high strength of pure cotton compact Siro-spun yarn improve the fabric's abrasion resistance, reduce surface pilling, fuzzing, or color fading, and thus improve the fabric's quality.

[0041] Furthermore, the periodic coarse yarn 2 is a pure cotton compact yarn with a count of 30s-40s and a twist direction of Z.

[0042] Understandably, by using a compact spinning process with periodic coarse yarn 2, the fabric becomes more delicate in feel, reducing roughness, while also improving the durability of periodic coarse yarn 2.

[0043] Furthermore, the elastic yarn 3 is made of spandex with a fineness of 50D-60D, which allows it to provide sufficient elasticity while maintaining good concealment and hand feel, avoiding the fabric from being too thick or too heavy.

[0044] In some preferred embodiments, the fabric weight is 285-315 g / m². 2 This ensures that the finished garments have the proper crispness and drape.

[0045] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
