Multicolor jacquard weaving method for heat-insulating air layer of coils arranged in a 1:1 ratio on both sides

Abstract

This invention discloses a multi-color jacquard knitting method for an air layer with a 1:1 ratio of loops on both sides, resulting in excellent heat insulation. The method involves rationally arranging the weaving position and sequence of the reverse weaving yarns to achieve a 1:1 loop ratio on both sides of the fabric. This ensures a dense effect on both sides of the three-color or higher air layer jacquard weave, providing excellent heat insulation performance. Elastic and functional yarns are used in a tucked knitting technique in the middle layer of the fabric, connecting the two sides together. This preserves the air layer structure while connecting the outer surfaces of the air layer, maintaining a fixed interlayer spacing and simultaneously enhancing its heat insulation function. The heat insulation function of the fabric can be adjusted and controlled by using different types and quantities of functional yarns. Furthermore, the functional yarns are only woven in the middle of the air layer structure and do not appear in the surface weave structure, thus not affecting the fabric's appearance or feel.

Description

Technical Field

[0001] This invention relates to the field of computerized flat knitting machines in the field of knitting and textile technology, specifically to a multi-color jacquard knitting method with heat-insulating air layer using a 1:1 arrangement of loops on both sides. Background Technology

[0002] When performing multi-color air-layer jacquard knitting on a flat knitting machine, the current knitting method is as follows: the two-color jacquard patterns are presented with the same pattern on both sides but opposite colors, resulting in a double-sided effect. The number of loops is arranged in a 1:1 ratio on both sides. With the same yarn count, the jacquard structure can be dense on both sides. The front and back sides form a double-layer structure, with a seamless transition at the edges where the jacquard colors alternate.

[0003] For jacquard with three or more colors in the air layer, the yarn loops woven on the front needle plate need to correspond to two or more other yarn loops on the back needle plate. When the yarn count is the same, the ratio of the number of loops on the front and back is often greater than 1:1, which causes the front needle plate loops to be stretched. This results in a sparse fabric density on one side, reduced heat retention, and problems such as jacquard pattern deformation and exposure of yarn colors on the other side.

[0004] In conventional air-layer jacquard weaving, the pattern color is woven into loops on the front needle plate, while other colored yarns are woven into loops on the back needle plate. As a result, there are no connection points between the two sides of the fabric, leading to separation of the front and back fabrics. This is especially noticeable when the pattern color block area is large.

[0005] In addition, when adding functional yarns to jacquard fabrics, the method of blending or adding yarns is usually used to weave the functional yarns and jacquard yarns at the same time. As a result, the functional yarns will appear in the surface structure of the fabric, thus affecting the appearance and feel of the fabric.

[0006] Currently, most functional yarns, such as graphene yarns, do not meet the requirements of computerized flat knitting machines in terms of strength, elasticity, yarn count, and twist. When knitting in loops, they have problems such as insufficient strength leading to breakage and insufficient elasticity making it difficult to form loops.

[0007] Based on the above problems, the inventors have conducted in-depth research on the air-layer multicolor jacquard knitting method of flat knitting machines, especially on cases with more than 3 colors, in order to design a new knitting method that can solve the above problems, so that air-layer jacquard knitwear can have a better fashion appearance and warmth, while reducing the cost of achieving the same effect. Summary of the Invention

[0008] To overcome the aforementioned problems, the inventors conducted in-depth research and designed a multi-color jacquard weaving method for an insulating air layer with 1:1 loop arrangement on both sides. This method involves rationally arranging the weaving position and sequence of the reverse weaving yarns, ensuring a 1:1 loop arrangement on both sides of the fabric. This results in a dense effect on both sides of the three-color or higher air layer jacquard weave, providing excellent insulation performance. Elastic and functional yarns are used in a tucked weave in the middle layer of the fabric, connecting the two sides together. This preserves the air layer structure while connecting the outer surface of the air layer, maintaining a fixed interlayer spacing and simultaneously enhancing its insulation function. The insulation function of the fabric can be adjusted and controlled by using different types and quantities of functional yarns. Furthermore, the functional yarns are woven only in the middle of the air layer structure and do not appear in the surface weave structure, thus not affecting the fabric's appearance and feel, thereby completing this invention.

[0009] Specifically, the purpose of this invention is to provide a multi-color jacquard knitting method for heat-insulating air layer with 1:1 front and back loops. In this method, based on the pattern requirements, yarn of a specified color in the pattern is selected to perform loop knitting on the front needle plate needles, while the remaining yarn is used to perform loop knitting on the back needle plate needles according to a predetermined needle arrangement pattern.

[0010] The number of loops woven on the back needle plate is the same as the number of loops woven on the front needle plate.

[0011] In this process, knitting is performed on the back needle plate needles by knitting and pulling floats.

[0012] The predetermined stitch pattern is as follows: after knitting one loop for each color of yarn, knitting is performed again on the same row after skipping n-1 loops;

[0013] Where n represents the number of colors involved in the pattern.

[0014] In this process, when knitting each row of loops on the front and back needle plates, a yarn feeder loaded with fine elastic yarn and functional yarn is simultaneously introduced to perform tuck knitting between the front and back needle plates. This prevents the fabric from separating on the front and back sides, fixes the interlayer spacing between the front and back sides of the fabric, improves the fabric structure stability, and enhances the warmth retention effect.

[0015] The tuck knitting can be selected from one or more of the following different needle position interval tuck knitting: full tuck knitting in four flat needle positions, tuck knitting with skipped needles in 1*1 rib needle positions, tuck knitting with skipped needles in 2-2 skipped needle positions, tuck knitting arranged regularly in a spacing of less than 1 inch, or one or more rows of tuck knitting.

[0016] The fine elastic yarn is spandex yarn;

[0017] The functional yarn is graphene yarn, other functional yarn, or untwisted filament fiber.

[0018] Among them, the number of tucked rows with functional yarns shall not exceed the number of rows of main yarns, and the total count of yarns in each row shall not exceed the count of the main yarns.

[0019] The beneficial effects of this invention include:

[0020] (1) According to the present invention, the heat-insulating air layer multicolor jacquard weaving method of the front and back side 1:1 arrangement of coils can be set with more than 3 colors, making the jacquard fabric more colorful, the pattern more free, the surface texture more dense, and the heat-insulating effect better.

[0021] (2) According to the present invention, the heat-insulating air layer multicolor jacquard weaving method of the front and back side 1:1 arrangement of coils provides a method in which functional yarns such as graphene fiber are added to the middle layer at the same time, which increases the thermal resistance of the fabric and improves the warmth of the fabric. The warmth is higher than that of the fabric without functional yarns under the same conditions, and the surface touch is completely the same as the outer yarn jacquard fabric, without affecting the appearance and touch.

[0022] (3) According to the present invention, the heat-insulating air layer multicolor jacquard weaving method of the front and back side 1:1 arrangement of coils is provided. In this method, the elastic yarn such as spandex yarn is mixed and used to make the functional yarn such as graphene reach the strength required for weaving. It does not make loop weaving, but only makes tufted loops, which reduces the process of loop forming and loop unwinding, and reduces the requirements for the strength and elasticity of the yarn during weaving. It enables more common functional yarns on the market to be used for weaving this structured fabric, such as untwisted filament fibers and other functional yarns that are not specially used for flat knitting, which greatly reduces the cost of using functional yarns.

[0066] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present invention will become clearer and more apparent.

[0067] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments. Although various aspects of embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated otherwise.

[0068] According to the present invention, a multi-color jacquard knitting method for heat-insulating air layer with 1:1 front and back loop arrangement is provided. In this method, based on the pattern requirements, yarn of a specified color in the pattern is selected to perform loop knitting on the front needle plate needles, while the remaining yarn is used to perform loop knitting on the back needle plate needles according to a predetermined needle arrangement pattern.

[0069] The number of loops knitted on the back needle plate is the same as the number of loops knitted on the front needle plate. This consistency ensures that the loops on the front side of the fabric will not be stretched or deformed, and the fabric can have a dense structure on both sides, providing good heat retention. The pattern on the front side will not be deformed, and the color of the yarn on the other side will not be exposed.

[0070] Preferably, knitting is performed on the back needle plate using a combination of knitting and float knitting. In this application, based on pattern requirements, yarn of a specified color from the pattern is selected for loop knitting on the front needle plate, while the remaining yarn is used for loop knitting on the back needle plate according to a predetermined stitch arrangement. When the same yarn is knitting on the back plate, the stitches in the same row are connected by a float knitting method. This float knitting is present between the front and back needle plate fabrics and does not appear on either side of the fabric, thus not affecting the fabric's appearance and increasing the warmth retention of the air layer fabric. Preferably, when the float knitting length between two adjacent loops of the same yarn in the same row exceeds 1 inch, one back plate tuck knitting stitch can be added to reduce the float knitting length to less than 1 inch, ensuring stable knitting without altering the loop ratio between the front and back needle plates.

[0071] In a preferred embodiment, the predetermined needle arrangement rule is as follows: after knitting one loop for each color yarn, knitting is performed again in the same row after skipping n-1 loops; for the same color, the same needle arrangement rule is executed on each row of the back needle plate.

[0072] Where n represents the number of colors involved in the pattern, and its value can be from 2 to 8, or even larger values, to set more complex patterns.

[0073] In a preferred embodiment, when knitting each row of loops on the front and back needle plates, a yarn feeder threaded with fine elastic yarn and functional yarn is simultaneously introduced to perform tuck knitting between the front and back needle plates, so that the front and back sides of the fabric are not separated, the interlayer spacing between the front and back sides of the fabric is fixed, the fabric structure stability is improved, and the warmth retention effect is enhanced.

[0074] In this application, the functional yarn is only knitted in the middle of the air layer structure by the front and back needle plates and will not appear on the surface of the fabric, so it will not affect the appearance, feel and other fabric properties of the fabric.

[0075] In this application, by using elastic yarns (such as spandex yarns) in combination, the yarn achieves the strength required for weaving, and instead of making loops, only tufting loops is used, which reduces the process of loop formation and unraveling, and lowers the requirements for the strength and elasticity of the yarn during weaving; thus enabling more commonly available functional yarns on the market to be used for weaving this type of fabric.

[0076] Preferably, the tuck knitting can be selected from one or more of the following different needle position interval tuck knitting: full tuck knitting in four flat needle positions, tuck knitting with skipped needles in 1*1 rib needle positions, tuck knitting with skipped needles in 2-2 skipped needle positions, tuck knitting arranged regularly in a spacing of less than 1 inch, or one or more rows of tuck knitting.

[0077] Preferably, the fine elastic yarn is spandex yarn;

[0078] The functional yarn is graphene yarn, other functional yarn, or untwisted filament fiber.

[0079] Preferably, the number of loops in which functional yarns are incorporated does not exceed the number of loops in which the main yarn is woven, and the total count of yarns in each loop does not exceed the count of the main yarn. In this application, by controlling the quantity and density of functional yarns such as graphene yarns used, the thermal resistance of the fabric is increased based on the properties of the original outer yarn and the warmth provided by the air layer structure, in order to improve the warmth retention of the fabric.

[0080] In this application, after each pattern row is finished, the fine elastic yarn and functional yarn can be knitted in a 1X1 rib stitch position between the front and back needle plates;

[0081] After each row of the pattern is finished, the fine elastic yarn and functional yarn can be knitted in a loop with one stitch between the front and back needle plates;

[0082] After each pattern row is finished, the fine elastic yarn and functional yarn can be knitted in a loop with two stitches between the front and back needle plates.

[0083] Alternatively, after each row of the pattern is finished, fine elastic yarn and functional yarn can be used for tuck knitting at a needle position within one inch between the front and back needle plates.

[0084] Alternatively, after each pattern row is finished, fine elastic yarn and functional yarn can be used for tuck knitting in four-stitch positions between the front and back needle plates.

[0085] The optimal solution in this application is to select a knitting scheme based on factors such as the yarn count and elasticity of the functional yarn, and to select needles with the smallest possible knitting interval while ensuring maximum looseness between the front and back needle plates. In this application, the fine elastic yarn and functional yarn can be knitted in tuck loops after the front and back needle plates of each pattern row have been knitted.

[0086] You can also perform a tuck knitting of fine elastic yarn and functional yarn after completing a portion of the front and back needle plates of each pattern row, and perform tuck knitting of fine elastic yarn and functional yarn multiple times in total;

[0087] The optimal solution in this application is to evenly distribute the required fine elastic yarn and functional yarn in the knitting rows between the knitting rows.

[0088] In this application, each time the fine elastic yarn and functional yarn are knitted in a loop, only one process row of the fine elastic yarn and functional yarn loop can be knitted.

[0089] Alternatively, multiple process rows of fine elastic yarn and functional yarn can be continuously knitted each time the fine elastic yarn and functional yarn are knitted together.

[0090] The optimal solution in this application is: each time the fine elastic yarn and functional yarn are knitted in a loop, only one process row of fine elastic yarn and functional yarn loops is knitted.

[0091] Example 1

[0092] The fabric to be woven uses a 3-color air-layer jacquard technique, and its pattern is as follows: Figure 1-1 As shown, its weaving method is as follows:

[0093] Based on the pattern requirements, select the yarn of the specified color in the pattern to perform loop knitting on the front needle plate needles, and at the same time use the remaining yarn to perform loop knitting on the back needle plate needles according to the predetermined needle arrangement pattern.

[0094] The number of loops woven on the back needle plate is the same as the number of loops woven on the front needle plate.

[0095] On the back needle plate, knitting is done by knitting and pulling floats;

[0096] The predetermined stitch arrangement rule is as follows: after knitting one loop for each color of yarn, knitting is performed again on the same row after skipping n-1 loops;

[0097] Where n represents the number of colors involved in the pattern, and its value is 3;

[0098] While knitting each row of loops on the front and back needle plates, simultaneously bring in a yarn feeder loaded with fine elastic yarn and functional yarn to perform tuck knitting between the front and back needle plates.

[0099] Among them, the knitting stitch arrangement method is as follows Figure 1-2 As shown in the diagram, this is a schematic diagram of the knitting effect of two rows of fabric. In terms of knitting stitch arrangement, it represents one cycle unit. The first row at the bottom of the diagram represents the jacquard colors of the fabric: color A represents gray, color B represents blue, and color C represents white. Rows 1, 2, 3, and 4 are the knitting process rows, using four process rows to complete one pattern row in the actual knitted fabric. That is, rows 1, 2, 3, and 4 are one row of loops each on the right and wrong sides of the actual fabric. Rows 5, 6, 7, and 8 are the knitting process rows, using four process rows to complete one pattern row in the actual knitted fabric. That is, rows 5, 6, 7, and 8 are one row of loops each on the right and wrong sides of the actual fabric.

[0100] In the first row of the fabric pattern row ( Figure 1-2 (Complete the first row of the pattern row using process rows numbered 1-4):

[0101] The first row of the process row is woven with yarn of color A (e.g., ...). Figure 1-2(Row 1, number 1) Knit the front plate loops in the A color pattern section, that is, knit the loops on the front needle plate needles; knit the back plate even-numbered loops in the B color pattern section, that is, knit the loops on the even-numbered positions of the back needle plate needles; knit the back plate odd-numbered loops in the C color pattern section, that is, knit the loops on the odd-numbered positions of the back needle plate needles.

[0102] The second row of the process row is woven with color B yarn (e.g., ...). Figure 1-2 (Row 2 in the middle), weave the front plate coil in the B color pattern section, weave the back plate even-numbered coil in the A color pattern section, and weave the back plate even-numbered coil in the C color pattern section;

[0103] The C-colored yarn is used for the third row of the process weaving (e.g., ...). Figure 1-2 (3rd row of numbers), weave the front plate coil in the C color pattern section, weave the back plate odd number of coils in the A color pattern section, and weave the back plate odd number of coils in the B color pattern section;

[0104] In the fourth process row, elastic yarns and functional yarns are tucked together between the front and back plates, with odd-numbered positions tucked together on the front plate and even-numbered positions tucked together on the back plate.

[0105] In the second row of the fabric pattern ( Figure 1-2 (Complete the second row of the pattern row using process rows numbered 5-8):

[0106] Color A yarn is used for the 5th row of the process weaving (e.g.) Figure 1-2 (5th row of numbers in the middle), weave the front plate coil in the A color pattern section, weave the even-numbered coils in the B color pattern section, and weave the odd-numbered coils in the C color pattern section;

Figure 1-2 (Row 7 in the middle), weave the front plate coil in the C-color pattern section, weave the back plate odd-numbered coil in the A-color pattern section, and weave the back plate odd-numbered coil in the B-color pattern section;

[0109] In the 8th process row, elastic yarn and functional yarn are gathered between the front and back plates, with odd-numbered positions gathered on the back plate and even-numbered positions gathered on the front plate.

[0110] Weaving techniques such as Figure 1-3 As shown in the needle position loop diagram, each needle position has one loop on the front needle plate and one loop on the back needle plate, with the functional yarn gathered between the front and back needle plates.

[0111] Fabric surface effect (front side) Figure 1-4The reverse side is as follows Figure 1-5 The fabric exhibits a dense effect on both sides. Elastic yarns and functional yarns are woven in loops in the middle layer of the fabric, linking the two sides of the fabric together. While retaining the air layer structure, it connects the outer side of the air layer, giving it a fixed interlayer spacing.

[0112] Example 2

[0113] The fabric to be knitted uses a 4-color air-layer jacquard technique, and its pattern is as follows: Figure 2-1 As shown, the same weaving method as in Example 1 is used:

[0114] Among them, the knitting stitch arrangement method is as follows Figure 2-2 As shown in the diagram, this is a schematic diagram of the knitting effect of two rows of fabric. In terms of stitch arrangement, it represents one cycle unit. The first row at the bottom of the diagram represents the jacquard colors of the fabric: A represents gray, B represents blue, C represents white, and D represents green. Rows 1, 2, 3, 4, and 5 are the knitting process rows. Five process rows are used to complete one pattern row in the actual knitted fabric; that is, rows 1, 2, 3, 4, and 5 are one row of stitches each on the right and wrong sides of the actual fabric. Rows 6, 7, 8, 9, and 10 are the knitting process rows. Five process rows are used to complete one pattern row in the actual knitted fabric; that is, rows 6, 7, 8, 9, and 10 are one row of stitches each on the right and wrong sides of the actual fabric. Every three stitches in the back panel form a cycle unit, starting from the first stitch at the edge of the fabric.

[0115] In the first row of the fabric pattern row ( Figure 2-2 (Complete the first row of the pattern row using process rows numbered 1-5):

[0116] The first row of the process row is woven with yarn of color A (e.g., ...). Figure 2-2 (Row 1, number 1) Knit the front plate loops in the A-color pattern section, knit the second loop in each cycle unit of the back plate in the B-color pattern section, knit the second loop in each cycle unit of the back plate in the C-color pattern section, and knit the second loop in each cycle unit of the back plate in the D-color pattern section; when the float length between two adjacent loops of the B-color yarn in the same row of the back plate is more than 1 inch, add 1 stitch of back plate tuck knitting to make the float length less than 1 inch for stable knitting;

[0117] The second row of the process row is woven with color B yarn (e.g., ...). Figure 2-2 (Row 2 in the middle), weave the front plate coil in the B color pattern section, weave the second coil in each loop unit of the back plate in the A color pattern section, weave the first coil in each loop unit of the back plate in the C color pattern section, and weave the third coil in each loop unit of the back plate in the D color pattern section.

[0120] In the fifth process row, elastic yarns and functional yarns are alternately gathered between the front and back plates.

[0121] In the first row of the fabric pattern row ( Figure 2-2 (Complete the second row of the pattern row using process rows numbered 6-10):

[0122] Color A yarn is used for the 6th row of the process weaving (e.g.) Figure 2-2 (6th row of the middle number), weave the front plate coil in the A color pattern section, weave the second coil in each loop unit of the back plate in the B color pattern section, weave the second coil in each loop unit of the back plate in the C color pattern section, and weave the second coil in each loop unit of the back plate in the D color pattern section.

[0126] In the 10th process row, elastic yarns and functional yarns are alternately gathered between the front and back plates.

[0127] Weaving techniques such as Figure 2-3 As shown in the needle position loop diagram, each needle position has one loop on the front needle plate and one loop on the back needle plate, with the functional yarn gathered between the front and back needle plates.

[0128] Fabric surface effect (front side) Figure 2-4 The reverse side is as follows Figure 2-5 The fabric exhibits a dense effect on both sides. Elastic yarns and functional yarns are woven in loops in the middle layer of the fabric, linking the two sides of the fabric together.

[0190] Fabric surface effect (front side) Figure 5-4 The reverse side is as follows Figure 5-5 The fabric exhibits a dense effect on both sides. Elastic yarns and functional yarns are woven in loops in the middle layer of the fabric, linking the two sides of the fabric together. While retaining the air layer structure, it connects the outer side of the air layer, giving it a fixed interlayer spacing.

Rows 1, 2, 3, 4, 5, 6, 7, 8, and 9 are the knitting process rows.

Rows 10, 11, 12, 13, 14, 15, 16, 17, and 18 are the knitting process rows.

[0247] The thermal resistance of the woven fabric obtained in this embodiment is 0.113 m²·K / W.

[0248] Comparative Example 1

[0249] The fabric to be knitted uses a two-color air-layer jacquard technique, and its pattern is as follows: Figure 14-1 As shown, its weaving method is as follows:

[0250] The front needle plate knits yarn A to form loops of color A, and the back needle plate knits yarn B to form loops of color B. The ratio of loops on the front and back sides of the fabric is 1:1. Since the yarns are of the same thickness, loops on one side can just cover loops on the other side.

[0251] The two layers of fabric of color A and color B will be connected at the edge of the alternating color blocks. However, there is no connection point between the fabrics on both sides in the middle of the color block area, which will result in the separation of the front and back fabrics.

[0252] Knitting stitch pattern as follows Figure 14-2 As shown in the diagram, this is a schematic diagram of the weaving effect of two rows of fabric, which is a cycle unit in terms of the weaving stitch method:

[0253] In the A-color pattern section: A-color yarn is used to weave the front plate loops, and B-color yarn is used to weave the back plate loops;

[0254] In the B-color pattern section: B-color yarn is used to weave the front plate loops, and A-color yarn is used to weave the back plate loops;

[0255] Weaving techniques such as Figure 14-3 As shown in the needle coil diagram, each needle position has one coil on the front needle plate and one coil on the back needle plate.

[0256] Fabric surface effect (front side) Figure 14-4 The reverse side is as follows Figure 14-5 The fabric is flat and free of impurities. The front and back fabrics are only connected at the edges where the colors of color blocks A and B alternate. Within the color block area, the front and back fabrics are separated.

[0257] Comparative Example 2

[0258] The fabric to be knitted uses a 4-color air-layer jacquard process, employing the same knitting method as in Comparative Example 1, resulting in a fabric as shown below. Figure 15 As shown in the image.

[0259] Because the back panel has a jacquard pattern with three or more colors of air layer, the yarn woven on the front side needs to correspond to the three yarns on the back panel. When the yarn count is the same, the ratio of loops on the front and back sides is often 3:1. As a result, the loops on the front panel are stretched, resulting in a sparse density on one side, which reduces its heat insulation performance. The front and back fabrics are only connected at the edges where the colors alternate, and the front and back fabrics are separated in some areas within the color block area.

[0260] As can be seen from the above embodiments and comparative examples, the multi-color jacquard weaving method for heat-insulating air layer with 1:1 coil arrangement on both sides provided in this application is particularly suitable for woven fabrics with more than 3 colors, and can obtain high-quality woven fabrics with a dense outer layer, good heat insulation performance, fixed interlayer spacing between the double-layer structure of the fabric and retention of air layer.

[0261] The present invention has been described above with reference to preferred embodiments; however, these embodiments are merely exemplary and illustrative. Various substitutions and modifications can be made to the present invention based on these embodiments, all of which fall within the scope of protection of the present invention.

The number of loops woven on the back needle plate is the same as the number of loops woven on the front needle plate. On the back needle plate, knitting is performed by knitting and pulling floats. Based on the pattern requirements, yarn of a specified color in the pattern is selected to perform loop knitting on the front needle plate. At the same time, the remaining yarn is used to perform loop knitting on the back needle plate according to the predetermined needle arrangement.
