Description

Technical Field

[0001] This utility model relates to the field of knitting technology, specifically to a double-sided air-layer fabric. Background Technology

[0002] Air-layer fabric is a type of fabric that allows air to be trapped between its layers. Double-sided air-layer fabric has a simpler structure, consisting of a front and a back layer connected by connecting yarns. The presence of more air between the front and back layers enhances the fabric's warmth retention.

[0003] Conventional double-sided air-layer fabrics have a weft-knit weave on both the front and back sides. The weft-knit weave has a simple structure, but the loop structure is relatively unstable and prone to skewing. There is a large relative range of motion between the front and back sides, which makes the fabric prone to stubborn wrinkles that need to be removed by ironing. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a double-sided air layer fabric that is less prone to stubborn wrinkles than conventional double-sided air layer fabrics.

[0005] To solve this technical problem, this utility model provides a double-sided air layer fabric. The front and back weaves of the double-sided air layer fabric are connected by connecting yarns, and there is an air layer between the front and back weaves. The double-sided air layer fabric is a two-sided fabric. The loop density of the front weave is half that of the back weave. One loop warp of the front weave corresponds to two loop warp of the back weave. The pattern of the front weave is formed by at least two pattern units arranged in a regular pattern.

[0006] Optionally, the pattern of the front part is a striped pattern formed by the regular arrangement of three pattern units.

[0007] Optionally, the three flower pattern units are a first flower pattern unit, a second flower pattern unit, and a third flower pattern unit; the smallest repeating unit of the front-side flower pattern is a flower pattern array composed of nine flower pattern units. The flower pattern array includes a first group, a second group, and a third group arranged sequentially along a first direction. The first group includes a second flower pattern unit, a third flower pattern unit, and a first flower pattern unit arranged sequentially along a second direction. The second group includes a third flower pattern unit, a first flower pattern unit, and a second flower pattern unit arranged sequentially along a second direction. The third group includes a first flower pattern unit, a second flower pattern unit, and a third flower pattern unit arranged sequentially along a second direction. The first direction is perpendicular to the second direction.

[0008] Optionally, the floral unit comprises 14 rows and 14 columns.

[0009] Optionally, the coil density of the front-side structure is 40 longitudinal rows / 5cm and 78 transverse rows / 5cm.

[0010] Optionally, the front structure includes a first yarn and a second yarn, the first yarn being a staple yarn and the second yarn being a filament yarn, the first yarn being thicker than the second yarn, so that the loops formed by the first yarn have more protrusions than the loops formed by the second yarn.

[0011] Optionally, the first yarn is a 16S cotton / wool blended yarn, and the second yarn is a 150D polyester / spandex covered yarn.

[0012] Optionally, the reverse side structure includes a second yarn and a third yarn, wherein the third yarn is a 300D polyester heating wire.

[0013] Optionally, the double-sided air-layer fabric is composed of 75% cotton, 10% wool, 13% polyester, and 2% spandex, and has a weight of 330 g / m². 2 .

[0014] Compared with conventional double-sided air layer fabrics, the double-sided air layer fabric provided by this utility model has a tight reverse weave structure, strong resistance to deformation, and greater elasticity in the transverse direction, which can resist the formation of wrinkles to a certain extent. The pattern of the front weave is formed by at least two pattern units arranged in a regular pattern. Compared with the simple weft plain knit weave, the binding force between the loops is greater, and it is not easy to cause large displacement and deformation. Attached Figure Description

[0015] Figure 1 This is a front view of an embodiment of the present utility model.

[0016] Figure 2 This is a reverse side view of an embodiment of the present invention. Detailed Implementation

[0017] This invention provides a double-sided air-layer fabric, in which the front and back weaves are connected by connecting yarns, and an air layer exists between the front and back weaves. Unlike conventional double-sided air-layer fabrics, this fabric is a two-sided fabric, where the loop density of the front weave is half that of the back weave, one loop warp of the front weave corresponds to two loop warp of the back weave, and the pattern of the front weave is formed by a regular arrangement of at least two pattern units. Here, a two-sided fabric refers to a fabric with significant differences between its front and back sides, exhibiting different colors, textures, or functions on each side.

[0018] The reverse side of this double-sided air-layer fabric has a tight weave structure, strong resistance to deformation, and significant lateral elasticity, which helps to resist wrinkles to a certain extent. The front side has a more complex weave pattern than plain weave, with greater binding force between loops, making it less prone to large-scale displacement and deformation.

[0019] The knitting method for this double-sided air-layer fabric is as follows: During the knitting process, the yarn length fed into the front and back loops is controlled according to the different requirements of the front and back loops, so that different sizes of loops are formed on the front and back of the knitted fabric, achieving different loop densities. Taking a double-sided circular knitting machine as an example, a double-sided circular knitting machine typically has cylinder needles (knitting one side, such as the back) and disc needles (knitting the other side, such as the front). The machine is equipped with two independent yarn feeding devices (usually achieved through a yarn feeder), corresponding to the cylinder needles and disc needles respectively. The loop density is controlled by adjusting the speed or tension of the yarn feeding devices. If a smaller front loop (higher density) is required, the yarn length fed to the front (disc needles) is reduced (or the tension is increased). If a smaller back loop (higher density) is required, the yarn length fed to the back (cylinder needles) is reduced (or the tension is increased). On the side with less yarn fed, the yarn is pulled tighter, resulting in smaller and denser loops; on the side with more yarn fed, the loops are relatively looser and less dense.

[0020] In one embodiment of this utility model, the front weave pattern is a striped pattern formed by the regular arrangement of three types of pattern units, and the smallest repeating unit is a pattern array composed of nine pattern units. The front weave is formed by the regular repetition of multiple smallest repeating units. See the artist's diagram for the front weave. Figure 1 . Figure 1 A minimum cycle unit can be seen, and regions with different gray levels are different flower pattern units.

[0021] See Figure 1 A single pattern unit comprises 14 rows and 14 columns, and a minimum cycle unit comprises 42 rows and 42 columns. The three pattern units are the first pattern unit, the second pattern unit, and the third pattern unit. The minimum cycle unit pattern array comprises a first group, a second group, and a third group arranged sequentially along a first direction. The first group comprises a second pattern unit, a third pattern unit, and a first pattern unit arranged sequentially along a second direction. The second group comprises a third pattern unit, a first pattern unit, and a second pattern unit arranged sequentially along a second direction. The third group comprises a first pattern unit, a second pattern unit, and a third pattern unit arranged sequentially along a second direction. The first direction is perpendicular to the second direction.

[0022] The front structure comprises a first yarn and a second yarn. The first yarn is a staple fiber yarn, and the second yarn is a filament yarn. The first yarn is thicker than the second yarn, resulting in more raised loops in the loops formed by the first yarn compared to those formed by the second yarn. The filament is a long, continuous thread; its fibers are continuous. When it encounters a sharp object, a filament can be caught and easily pulled out along its direction, creating a snag. The staple fiber is made by cutting or breaking long fibers into various lengths; its fibers are segmented. When subjected to external force, even if individual short fibers are caught, they will not be pulled out continuously like filaments because the other short fibers will exert a binding effect, making it relatively less prone to significant snags.

[0023] Figure 1 In the diagram, "×" indicates the first yarn is threaded through, and "○" indicates the second yarn is threaded through. Because the loops formed by the first yarn are more convex than those formed by the second yarn, the first yarn can protect the second yarn. Simultaneously, the surface of the first yarn has some fuzz, which also cushions against snagging by sharp objects, reducing the possibility of snags. The interlacing of the first and second yarns creates a distinctive striped pattern, enhancing the appearance of the double-sided air-layer fabric. Furthermore, the rich texture on the front makes wrinkles less noticeable. The different loop patterns of the first and second yarns in the three pattern unit areas create different visual effects for each pattern unit. Those skilled in the art can design the loop patterns of the first and second yarns in the three pattern unit areas as needed; simply allowing the short fiber loops to slightly cover the long filament loops can enhance the anti-snagging performance of the fabric's front side.

[0024] The reverse side of this double-sided air-layer fabric consists of a second yarn and a third yarn. Figure 2 The "○" in the diagram indicates the second yarn, while the absence of an "×" or "○" indicates the third yarn. The first yarn is a 16S cotton / wool blend (containing both cotton and wool), the second yarn is a 150D polyester / spandex covered yarn (containing both polyester and spandex), and the third yarn is a 300D polyester heating yarn. On the reverse side of the fabric, the polyester / spandex covered yarn and the polyester heating yarn are interleaved in loops, resulting in a smooth fabric surface, a tight and stable structure, and effective contact between the polyester heating yarn and the human body, which is beneficial for the heating performance. Those skilled in the art can design the loop pattern of the polyester / spandex covered yarn and the polyester heating yarn on the reverse side of the fabric as needed, as long as the fabric surface is smooth, the structure is tight and stable, and the polyester heating yarn makes effective contact with the human body.

[0025] The double-sided air-layer fabric is composed of 75% cotton, 10% wool, 13% polyester, and 2% spandex, and has a weight of 330 g / m². 2 The width is 152cm.

[0026] The front side of this double-sided air-layer fabric is primarily composed of a cotton / wool blend yarn, offering excellent abrasion resistance and preventing snagging. The reverse side features polyester heating yarns that store and raise the temperature, working in conjunction with the air layer between the front and reverse sides to provide superior thermal insulation. This double-sided air-layer fabric retains the advantages of conventional double-sided air-layer fabrics (more air between the front and reverse sides) while enhancing its appearance, wrinkle resistance, and snag resistance.

[0027] The embodiments of this utility model are not limited to Figures 1 to 2 Based on the disclosure of this utility model, those skilled in the art will readily conceive of other embodiments of this utility model, such as increasing or decreasing the number of pattern units, changing the arrangement of pattern units in the smallest repeating unit, changing the composition of the fabric, or changing the weight and width of the fabric.
