Description

Technical Field

[0001] The present invention relates to the technical field of knitted fabrics, and in particular to a new type of twisted knitted fabric knitted based on a computerized flat knitting machine and a knitting method thereof. Background Art

[0002] Twisted knitted fabric, also called single-needle self-twisting jacquard fabric, refers to a fabric effect where a single loop rotates 180° by itself, causing the two loop columns in the loop to cross each other, forming a loop-in-loop effect. The traditional knitting method of twisted knitted fabric needs to be manually knitted on a hand-operated flat knitting machine. The technical key lies in: using a single-needle type stitch holder to transfer the loop from the knitting needle to the stitch holder, and after the stitch holder rotates 180°, the loop is then placed back on the knitting needle. This manual twisting process affects the knitting efficiency, and at the same time, the texture effect of the knitted twisted fabric is not obvious, and its decorative and practical properties are not strong.

[0003] If relying on the computerized flat knitting machine knitting technology to automatically knit the twisted knitted fabric through knitting equipment, the limitations of the traditional knitting method can be broken through, the knitting efficiency can be greatly improved, the production cost of knitted products of the twisted knitted fabric type can be reduced, providing the possibility for its automated large-scale production, and producers can, on the basis of the twisted knitted fabric, combine other knitting methods such as hanging needles, purling, and inter-color knitting to enrich the diversity of the knitted fabric structure, improve the performance and appearance texture effect of the fabric, and make it have stronger decorative and practical properties. Summary of the Invention

[0004] Other features and advantages of the present invention will be described in the following specification, and will be partially obvious from the specification, or understood by implementing the present invention. The objectives and other advantages of the present invention can be achieved and obtained through the structures specifically pointed out in the specification and other specification drawings.

[0005] The object of the present invention is to overcome the above deficiencies and provide a new type of twisted knitted fabric knitted based on a computerized flat knitting machine and a knitting method thereof. By splitting the knitting steps at the starting row of the twisted loop, another action row is separated from the twisted loop for separate knitting, and its knitting direction is opposite to that of other loops in the same row. Thus, when knitting the subsequent rows, the twisted loop is continuously twisted and stretched during the knitting process. When knitting to the last row, a purling action is set at the corresponding column position of the loop to complete the stitch receiving, making the surface of the whole knitted fabric more textured.

[0006] The present invention provides a knitting method for a new type of twisted knitted fabric knitted based on a computerized flat knitting machine, including

[0007] S1. Computer plate making: Draw the plate-making pattern of the new type of twisted knitted fabric in the plate-making system and input it into the computerized flat knitting machine;

[0008] S2. Yarn threading: Thread the yarn required for the twisted knitted fabric into a flat knitting machine, which is a double-bed flat knitting machine including a front bed and a back bed;

[0009] S3. Knitting: Start the flat knitting machine, and the flat knitting machine knits a new type of twisted knitted fabric with a single coil rotated 180° according to the pattern diagram;

[0010] S4. Cleaning: Low-temperature clean and air-dry the newly knitted twisted knitted fabric;

[0011] S5. Steam setting: Steam-set the air-dried new type of twisted knitted fabric;

[0012] The new type of twisted knitted fabric includes a fabric body and twisted needles. The fabric body is composed of weft plain coils on the back bed. The twisted needles are hanging needles on the front bed and are stretched and enlarged. The two loop columns of the twisted needles cross each other, causing a large coil to split into two small coils, and they are longitudinally suspended on the surface of the fabric body.

[0013] In some embodiments, the specific knitting steps of S3 are as follows:

[0014] S31. The flat knitting machine drives the yarn to knit 1 row of weft plain structure on the back bed, and sets a non-connected hanging needle coil on the front bed at the middle position of this row. The knitting direction of the non-connected hanging needle coil on the front bed is opposite to that of the other coils in this row;

[0015] S32. The flat knitting machine drives the yarn to continue knitting the weft plain structure on the back bed. The weft plain structure on the back bed lasts for at least 2 rows, and the non-connected hanging needle coil on the front bed is twisted and stretched;

[0016] S33. In the last row, when the flat knitting machine knits to the column position corresponding to the non-connected hanging needle coil on the front bed, set a purl action, that is, turn the non-connected hanging needle coil on the front bed to the back bed to complete the binding off, forming a twisted needle coil spanning at least 1 row;

[0017] S34. Repeat steps S31 - S33. Steps S31 - S33 are a complete cycle unit, and repeating this cycle unit forms a complete new type of twisted knitted fabric.

[0018] In some embodiments, in the step of S31, knitting the 1 row of weft plain structure on the back bed includes three action rows:

[0019] In the first action row, the flat knitting machine head knits several back bed coils from left to right;

[0020] In the second action row, the flat knitting machine head moves from right to left to the middle position and knits the non-connected hanging needle coil on the front bed at the middle position;

[0021] In the third action row, the knitting machine head continues to knit several needle bed coils on the right side of the non-connected hanging needle coils on the front needle bed from left to right.

[0022] In some embodiments, the yarn used in the S31 step may be different from the yarn used in the S32 step.

[0023] In some embodiments, in the new twisted needle fabric, the loop units are knitted with dislocation, and the twisted needle coils in the upper and lower loop units are in different columns.

[0024] In some embodiments, in the new twisted needle fabric, the loop units are arranged correspondingly for knitting, and the twisted needle coils in the upper and lower loop units are in the same column.

[0025] In some embodiments, in the S4 step, the formed new twisted needle fabric is taken off the knitting machine and put into a cleaning pool for cleaning. The water temperature in the cleaning pool does not exceed 45°C. After cleaning, the new knitted fabric is hung in a shaded place to dry naturally, avoiding direct sunlight exposure.

[0026] In some embodiments, a neutral detergent is placed in the cleaning pool. After the detergent is mixed with water, the pH value in the cleaning pool is between 6 and 8.

[0027] In some embodiments, in the S5 step, after the air-dried new twisted needle fabric is taken down and laid flat on a plane, a pressurized hanging ironing machine is used to steam-set it to fix the pattern of the twisted needle coils.

[0028] A new twisted needle fabric based on computerized knitting machine knitting. The new twisted needle fabric includes a fabric body and twisted needle coils. The fabric body is composed of weft plain coils on the back needle bed. The twisted needle coils are hanging needle coils on the front needle bed and are stretched and enlarged. The two loop columns of the twisted needle coils cross each other, so that a large coil is split into two small coils and is longitudinally suspended on the surface of the fabric body.

[0029] By adopting the above technical solutions, the beneficial effects of the present invention are:

[0030] In the present invention, by splitting the knitting steps at the starting row of the twisted needle coils, the twisted needle coils are separately knitted in another action row, and the knitting direction is opposite to that of other coils in the same row. Therefore, when knitting the subsequent rows, the twisted needle coils are continuously twisted and stretched during the knitting process. When knitting to the last row, a purl action is set at the corresponding column position of the coils to complete the binding off, forming a twisted needle coil rotated 180°, making the surface of the whole knitted fabric more textured and more practical.

[0031] The knitting method of the twisted knitted fabric of the present invention is adapted to the settings of a conventional flat knitting machine. The production of the new twisted knitted fabric can be achieved without additional components or structures. Moreover, through the yarn feeders in the flat knitting machine, the color combination and thickness of the knitted fabric can be changed to highlight the texture of the twisted stitches. Based on the twisted knitted fabric, other knitting methods such as tuck stitches, purl stitches, and intarsia in the existing flat knitting machine can be combined to enrich the diversity of the knitted fabric structure. Compared with the traditional manual knitting method, the knitting method using a computerized flat knitting machine is more efficient, has lower production costs, and more patterns.

[0048] Embodiment 1

[0049] Reference Figures 1-5 , Figure 1 is a schematic diagram of the coil structure of traditional twisted needle fabric in some embodiments of the present invention; Figure 2 is a schematic diagram of the coil structure of a new type of twisted needle fabric in some embodiments of the present invention; Figure 3 is a schematic diagram of the physical structure of a new type of twisted needle fabric in some embodiments of the present invention; Figure 4 is a plate-making pattern diagram in some embodiments of the present invention; Figure 5 is a flat knitting machine knitting diagram in some embodiments of the present invention.

[0050] According to some embodiments of the present invention, the present invention provides a new type of twisted needle fabric knitting method based on flat knitting machine knitting, including

[0051] S1. Computer plate-making: Draw the plate-making pattern diagram of the new type of twisted needle fabric in the plate-making system and input it into the flat knitting machine;

[0052] S2. Yarn threading: Thread the yarn required for the twisted needle fabric into the flat knitting machine, and this flat knitting machine is a double-needle bed flat knitting machine, including a front needle bed and a rear needle bed;

[0053] S3. Knitting: Start the flat knitting machine, and the flat knitting machine knits a new type of twisted needle fabric with a single coil rotated 180° according to the pattern diagram;

[0054] Among them, the equipment is a domestic Longxing double-system flat knitting machine, with the machine number LXC-252SC and the needle type 7 needles / 25.4 mm; the yarn raw material is 29.5 tex×2, 100% cotton yarn, and 3 yarns are fed in; the computer plate-making system is the Ruineng Qili 1121 plate-making system; the knitting parameter tuck value (the relative height of the tuck cam, corresponding to the size of the loop formation, that is, the fabric density) is 80, the roller value (the rotational speed of the roller motor per minute) is 15 r / min, the knitting speed value is 65 cm / s, and the knitting time spent on knitting a new type of twisted needle fabric with a size of 30 cm×30 cm is 3 min.

[0055] During the flat knitting machine knitting process, the tuck value in the common knitting parameters is used to represent the relative size of the loop. The larger the tuck value, the larger the loop formed by knitting and the smaller the fabric density; the larger the roller value, the greater the tension on the loop during knitting; the greater the knitting speed, the faster the knitting action of the flat knitting machine. Generally, for fabrics with low knitting difficulty, a faster knitting speed can be set.

[0056] Such as Figures 1-2As shown, the knitting method of traditional twisted stitch fabrics needs to be manually knitted on a hand-operated flat knitting machine. A single-needle type stitch holder is used to transfer the loops from the knitting needles to the stitch holder. After the stitch holder rotates 180°, the loops are then placed back onto the knitting needles. Therefore, the twisted stitch loops cannot span multiple rows. Based on the traditional twisted stitch fabrics, the new type of twisted stitch fabrics uses the method of multi-row hanging stitches to stretch and enlarge the loops that need to be twisted, and combines yarns of different colors and thicknesses for knitting, making the appearance texture effect of the twisted stitch fabrics more prominent.

[0057] According to some embodiments of the present invention, optionally, as Figure 4 shown, the specific knitting steps of S3 are as follows:

[0058] S31. The flat knitting machine drives the yarn to knit 1 row of plain stitch structure on the back needle bed, and sets a non-connected hanging stitch loop on the front needle bed at the middle position of this row. The knitting direction of this non-connected hanging stitch loop on the front needle bed is opposite to the knitting direction of the other loops in this row;

[0059] S32. The flat knitting machine drives the yarn to continue knitting the plain stitch structure on the back needle bed. This plain stitch structure on the back needle bed lasts for 7 rows, and the non-connected hanging stitch loop on the front needle bed is twisted and stretched;

[0060] S33. When the flat knitting machine knits to the corresponding column position of the non-connected hanging stitch loop on the front needle bed in the last row, a purl action is set, that is, the non-connected hanging stitch loop on the front needle bed is purled to the back needle bed to complete the stitch receiving, forming a twisted stitch loop 2 that spans 6 rows;

[0061] S34. Repeat the steps of S31 - S33. The steps of S31 - S33 are a complete cycle unit. Repeating this cycle unit forms a complete new type of twisted stitch fabric.

[0062] The yarn used in step S31 is different from the yarn used in step S32.

[0063] Specifically, each cycle structure unit of the twisted stitch fabric consists of 8 rows and 15 columns. First, use one color, such as white, to knit 1 row of plain stitch tissue on the back needle bed, and set a non-connected hanging stitch loop on the front needle bed at the middle position of this row, that is, the 8th column. Then use another color, such as red, to knit 7 rows of plain stitch tissue on the back needle bed, and set a purl action in the middle of the last row to complete the stitch receiving, forming a complete twisted stitch loop 2.

[0064] According to some embodiments of the present invention, optionally, in the step of S31, when knitting the 1 row of plain stitch structure on the back needle bed, it includes three action rows:

[0065] In the first action row, the flat knitting machine head knits 7 stitches of the back needle bed loop from left to right;

[0066] During the second action row, the knitting machine head moves from right to left to the 8th column position and knits the non-connected hanging needle loops on the front needle bed at the middle position.

[0067] During the third action row, the knitting machine head continues to knit 7 needle loops on the back needle bed on the right side of the non-connected hanging needle loops on the front needle bed from left to right.

[0068] Specifically, since the non-connected hanging needle loops on the front needle bed at the 8th column of the first row need to be rotated 180° to achieve twisted needle knitting, the starting row is split into three action rows by the method of row splitting, and the loops that need to be twisted are set as a separate action row, making its knitting direction opposite to that of the other loops in this row. Then, when knitting the subsequent rows, during the process of the knitting machine head driving the yarn to knit back and forth, the twisted needle loop 2 is gradually twisted and elongated, thus achieving a twisted needle loop 2 that spans 6 rows.

[0069] It should be understood that this action row refers to the movement route of the knitting machine head, which means that during the knitting process of the same row, the machine head has three actions. For the convenience of understanding, it is split into three rows and shown in the figure. It does not mean that three rows of weft are knitted in the steps of S31. Similarly, in the following description of the knitting pattern, the machine head actions at the starting row are split into three rows for description, and the actually knitted fabric is 8 rows and 15 columns.

[0070] As Figure 5 shown, the numbers "3" and "5" in the knitting area represent the yarn guide numbers, the light-colored loops represent the new loops of the knitting action row, the dark-colored loops represent the old loops, the arrows represent the loop turning to the front or the back, and the black arrow on the left side of the knitting area represents the running direction of the computerized knitting machine head.

[0071] In the first row, the computerized knitting machine head drives the 5th yarn guide with white cotton yarn to knit the 1st - 7th needle loops on the back needle bed from left to right; in the second row, the machine head drives the 5th yarn guide with white cotton yarn to knit the 8th non-connected loop on the front needle bed from right to left; in the third row, the machine head drives the 5th yarn guide with white cotton yarn to knit the 9th - 17th needle loops on the back needle bed from left to right; in the 4th - 9th rows, the machine head drives the 3rd yarn guide with red cotton yarn to knit 15 needle loops on the back needle bed back and forth for the whole row; in the 10th row, the turning needle action is performed to turn the non-connected hanging needle loop on the front needle bed at the 8th column to the back needle bed; in the 11th row, the machine head drives the 3rd yarn guide with red cotton yarn to knit 15 needle loops on the back needle bed for the whole horizontal row, and thus the knitting of a new type of twisted needle fabric with a cyclic structure unit can be completed.

[0072] By setting the yarn guide numbers in the 215 function bar, the color matching of the twisted needle fabric can be changed; the loops that need to be twisted are separately split into 1 row, and yarns of different colors and different thicknesses are selected for knitting, making the twisted needle loops stand out in the overall fabric and having a better visual appearance effect.

[0073] By changing the number of rows of hanging needles, the size of the twisted needle coils can be changed; by changing the number and position of the twisted needle coils, new types of twisted needle fabrics with different appearance forms and different texture effects can be obtained; since each twisted needle coil requires a separate action row to be disassembled to change the knitting direction, so as to achieve twisted needle knitting, under the same knitting speed, fabric specification size and other conditions, in the same row, the fewer the twisted needle coils, the fewer the number of disassembled action rows, and the higher the knitting efficiency.

[0074] According to some embodiments of the present invention, optionally, the present invention further provides a new type of twisted needle fabric knitted by a computerized flat knitting machine, as Figure 3 shown. The new type of twisted needle fabric includes a fabric body 1 and twisted needle coils 2. The fabric body 1 is composed of weft plain coils on the back needle bed. The twisted needle coils 2 are hanging needle coils on the front needle bed and are stretched and enlarged. The two loop columns of the twisted needle coils 2 cross each other, so that a large coil is split into two small coils and longitudinally hangs on the surface of the fabric body 1.

[0075] In this new type of twisted needle fabric, the loop units are knitted out of position, and the twisted needle coils in the upper and lower two loop units are in different columns.

[0076] According to some embodiments of the present invention, optionally, the knitting method further includes: S4. Cleaning: performing low-temperature cleaning and air drying on the knitted new type of twisted needle fabric; S5. Steam setting: performing steam setting on the air-dried new type of twisted needle fabric.

[0077] In this S4 step, the formed new type of twisted needle fabric is taken off the flat knitting machine and put into a cleaning pool for cleaning. The water temperature in the cleaning pool does not exceed 45°C, and a neutral detergent is placed in the cleaning pool. After the detergent is mixed with water, the pH value in the cleaning pool is between 6 and 8. After cleaning, the new type of knitted fabric is hung in a shaded place for air drying to avoid direct sunlight.

[0078] In this S5 step, after the air-dried new type of twisted needle fabric is taken off and laid flat on a plane, a pressurized hanging iron is used to perform steam setting on it to fix the pattern of the twisted needle coils 2.

[0079] Embodiment 2

[0080] The difference between this embodiment and Embodiment 1 is that:

[0081] According to some embodiments of the present invention, optionally, in the specific knitting steps of S3:

[0082] S31. The flat knitting machine drives the yarn to knit 1 row of weft plain structure on the back needle bed, and sets a non-connected hanging needle coil on the front needle bed at the middle position of this row. The knitting direction of the non-connected hanging needle coil on the front needle bed is opposite to the knitting direction of the rest of the coils in this row;

[0083] S32. The flat knitting machine drives the yarn to continue knitting the plain stitch structure on the back needle bed. This plain stitch structure on the back needle bed lasts for 5 rows, and the unconnected hanging needle loops on the front needle bed are twisted and elongated.

[0084] S33. In the last row of the flat knitting machine, when knitting to the position corresponding to the column of the unconnected hanging needle loops on the front needle bed, a purl stitch action is set, that is, the unconnected hanging needle loops on the front needle bed are purled to the back needle bed to complete the knitting-off, forming a twisted needle loop 2 that spans 4 rows.

[0085] S34. Repeat steps S31 - S33. Steps S31 - S33 are a complete cycle unit. Repeating this cycle unit forms a complete new type of twisted needle fabric.

[0086] The yarn used in step S31 is the same as the yarn used in step S32.

[0087] Specifically, each cycle structure unit of this twisted needle fabric consists of 6 rows and 15 columns. Using one color, such as white, knit 1 row of plain stitch on the back needle bed, and at the middle position of this row, that is, the 8th column, set the unconnected hanging needle loops on the front needle bed. Then use another yarn guide to drive the same color yarn to knit 7 rows of plain stitch on the back needle bed, and at the middle of the last row, set the purl stitch action to complete the knitting-off, forming a complete twisted needle loop 2.

[0088] In this new type of twisted needle fabric, the cycle units are knitted correspondingly, and the twisted needle loops in the upper and lower two cycle units are in the same column.

[0089] Embodiment 3

[0090] The difference between this embodiment and Embodiment 1 is as follows:

[0091] According to some embodiments of the present invention, optionally, in step S31, when knitting the 1 row of plain stitch structure on the back needle bed, it includes three action rows:

[0092] In the first action row, the flat knitting machine head knits 4 back needle bed loops from left to right.

[0093] In the second action row, the flat knitting machine head moves from right to left to the 5th column position and knits the unconnected hanging needle loop on the front needle bed at the middle position.

[0094] In the third action row, the flat knitting machine head continues to knit 4 back needle bed loops on the right side of the unconnected hanging needle loop on the front needle bed from left to right.

[0095] Each loop structure unit of the twisted knitted fabric consists of 8 rows and 9 columns. Using one color, such as white, knit 1 row of plain stitch on the back needle bed, and at the middle position of this row, that is, the 5th column, set the unconnected hanging needle loop on the front needle bed. Then use another yarn feeder to drive the yarn of a different color, such as green, and knit 7 rows of plain stitch on the back needle bed. And at the middle of the last row, set the purl action to complete the knitting of the needles, forming a complete twisted needle loop 2.

[0096] Specifically, in the 1st row, the computerized flat knitting machine head drives the 5th yarn feeder with white cotton yarn to knit the 1st - 4th back needle bed loops from left to right; in the 2nd row, the head drives the 5th yarn feeder with white cotton yarn to knit the 5th unconnected loop on the front needle bed from right to left; in the 3rd row, the head drives the 5th yarn feeder with white cotton yarn to knit the 6th - 9th back needle bed loops from left to right; in the 4th - 9th rows, the head drives the 3rd yarn feeder with red cotton yarn to knit 9 back needle bed loops back and forth for the whole row; in the 10th row, execute the purl action to turn the unconnected hanging needle loop on the front needle bed at the 8th column to the back needle bed; in the 11th row, the head drives the 3rd yarn feeder with red cotton yarn to knit 9 back needle bed loops for the whole horizontal row, then the knitting of a loop structure unit of the new type of twisted knitted fabric can be completed.

[0097] In this new type of twisted knitted fabric, the loop units are knitted out of alignment, and the twisted needle loops in the upper and lower two loop units are in different columns.
