Description

Technical Field

[0001] This invention belongs to the field of knitted textile technology, specifically relating to a three-dimensional relief effect knitted fabric and its weaving method. Background Technology

[0002] Three-dimensional knitting, also known as stereo knitting, uses specialized three-dimensional automatic knitting machines to create shaped or sheet-like fabrics with three-dimensional structures through techniques such as needle unwinding and tightening, row holding, wedge knitting, or multi-layer knitting. These fabrics can be used as the skeleton for industrial composite materials. However, products woven in this way differ from those produced by computerized flat knitting machines in terms of equipment, raw materials, appearance, properties, and quality.

[0003] Traditional knitted products with three-dimensional decorations are made by hand-knitting with knitting needles and then hand-sewing them to the designated positions on the product. This traditional method requires a large number of workers, has high production costs, is slow, has low production efficiency, and makes it difficult to standardize techniques and densities, resulting in inconsistent appearance and product quality, which directly restricts mass production. In addition, as skilled knitting workers age, fewer and fewer people are engaged in this industry, so this hand-knitting technique is gradually disappearing or being lost.

[0004] However, as market demands for product quality and uniqueness become increasingly stringent, these three-dimensional knitted fabrics still occupy a very large market share. How to knit three-dimensional relief knitted fabrics on fabrics in one go using a double-needle bed computerized flat knitting machine has become a pressing technical challenge. Summary of the Invention

[0005] The purpose of this invention is to provide a three-dimensional relief effect knitted fabric and a knitting method that can knit a knitted structure with a three-dimensional relief effect on the surface of the fabric.

[0006] To achieve the above objectives, the technical solution used in this invention is:

[0007] Methods for knitting fabrics with a three-dimensional embossed effect include:

[0008] The initial needle positions of the front and back needle beds are L0.5. The base tissue structure is woven in the back needle bed with a 1-stitch skipping-1-stitch exit pattern. The starting point coil of the three-dimensional relief structure is constructed at the target position point on the base tissue structure.

[0009] On the skipped stitch position of the reverse stitch loop, the front needle bed's regular stitch loop and the back needle bed's reverse stitch loop are knitted separately according to the local short return, and the loops between the two needle beds do not have mutual turning action, thus creating a three-dimensional relief structure.

[0010] Furthermore, the three-dimensional relief structure has a double-layered cylindrical structure on each side of the central axis. On the reverse stitch loops of the base structure, with the help of the three empty needle points of the back needle bed relative to the needle bed and the front and back needle beds at the skipped stitch positions, each loop of the front and back needle beds is gradually transferred to both sides, so that the double-layered cylindrical structure floats on the fabric surface and gradually extends outwards. On the reverse stitch loops of the base structure, with the help of the three empty needle points of the back needle bed relative to the needle bed and the front and back needle beds at the skipped stitch positions, each loop of the front and back needle beds is gradually transferred towards the central axis, so that the double-layered cylindrical structure floats on the fabric surface and gradually gathers inwards. The 1 front needle bed regular stitch loop on the central axis is flipped back to the back needle bed and integrated with the reverse stitch loops of the base structure, thus ending the knitting.

[0011] Furthermore, the fabric is knitted using a computerized flat knitting machine, which has at least one pair of front needle beds and a back needle bed facing each other, and has one or more system functions.

[0012] Furthermore, the computerized flat knitting machine has a sinker cam and a sinker cam. The sinker cam is used to push the sinker of the small needle bed when the knitting head is running, so that the sinker plays a role in knitting. The sinker is arranged next to each needle and is used to control the looping process of old loops and new yarns for each needle. The sinker is activated by the push of the sinker cam.

[0013] Furthermore, a three-dimensional relief structure is created by using multi-layer weaving, holding the horizontal rows, fixing the central axis, and tightening and loosening needles.

[0014] Furthermore, the knitting methods include partial back knitting and a rocking bed with left and right staggered plates between the needle beds, which allows the loops to be smoothly transferred to the designated target position.

[0015] Three-dimensional relief knitted fabric includes: a base structure and a three-dimensional relief structure. The three-dimensional relief structure is woven on the surface of the base structure to form a raised structure.

[0016] The technical effects of this invention include:

[0017] This invention enables the weaving of a knitted structure with a three-dimensional, embossed effect on the surface of fabric.

[0018] Using a standard computerized flat knitting machine with a double needle bed, the process is completed in one go, eliminating the need for specialized equipment. This transforms the complex manual knitting and sewing process, improving production efficiency and reducing production costs.

[0019] Three-dimensional embossed knitted fabrics achieve one-piece molding (one-line molding), resulting in greater integrity and thus enabling wider application in the research and development of apparel products.

[0020] Three-dimensional embossed knitwear, with its strong three-dimensional effect and unique style, brings a strong visual aesthetic to knitwear. Attached Figure Description

[0030] The following description fully illustrates specific embodiments of the invention to enable those skilled in the art to practice and reproduce them.

[0031] Computerized flat knitting machines are used to knit fabrics. These machines have at least one pair of front and back needle beds facing each other, and have one or more system functions. They can knit in a single system or in a dual system, thus improving knitting efficiency.

[0032] Computerized flat knitting machines have special Saucer cams and sinker cams. The Saucer cam pushes the sinker on the small needle bed when the knitting head is running, allowing the sinker to function during knitting. The sinker is located next to each needle and can effectively control the loop formation process of old loops and new yarns on each needle. The sinker can hold down the original loops and the new loops formed during knitting, preventing them from being carried away by the moving needles and causing the loops to break up, and also preventing the knitted loops from floating up. It works by being pushed by the Saucer cam, which is more advantageous for the principle of local return and kicking yarn guides to form loops.

[0033] Knitting techniques include partial short-row knitting and alternating left-right rocking beds between needle beds, allowing loops to be smoothly transferred to designated target positions. The computerized flat knitting machine's special needle selection mechanism effectively controls each needle for knitting or loop transfer, thus controlling various movements.

[0034] 1. Loop Formation (Knitting): With a yarn guide, a new loop is formed when the needle exits to 3 / 4 of its height;

[0035] 2. Floating yarn (not knitted): The needle emerges at 0 and no needle is inserted. It is equipped with a yarn guide and does not participate in knitting. The floating yarn is pulled.

[0036] 3. Turning the stitch: The stitch is turned at 4 / 4 of its exit height;

[0037] 4. Needle connection: Connect the loop on the needle at 1 / 4 of the needle height.

[0038] In this preferred embodiment, the computerized flat knitting machine is a domestic STG-M252CP, a 5 / 7 needle model, that is, a 7-needle / inch stitch length and a 5-needle stitch hook, which can hold multiple yarns. It is a dual-system computerized flat knitting machine, using 38.5tex / 2*3 (metric count 26S / 2*3) 100% cashmere yarn with a density of 7.5 rows / 25.4mm, and a Hengqiang 980 design system.

[0039] like Figure 1 The image shown is a schematic plan view of the three-dimensional relief effect knitted fabric of the present invention.

[0040] In a two-dimensional planar structure, design and construct a spatial system composed of the direction vectors of a rhombus block structure.

[0041] Based on the base reverse stitch loop structure A, a separate three-dimensional spatial structure is raised, and this structure is gradually moved outward by loop B and inward by loop C to knit an elliptical three-dimensional knitted fabric with an independent spatial structure floating on the surface of the fabric.

[0042] Methods for knitting fabrics with a three-dimensional embossed effect include:

[0043] The following explanations are provided for the labels in the subsequent diagrams: BB indicates the posterior needle bed, and FB indicates the anterior needle bed. The number indicates the yarn guide, the number + n indicates the number of stitches to shift, the numbers on the bottom row indicate each corresponding needle, and the arrow indicates the knitting or turning direction.

[0044] like Figure 2 The image shown is a plan view of the knitting loop structure of the initial starting position of the three-dimensional relief knitted fabric according to the present invention.

[0045] Step 1: The initial needle positions of the front needle bed FB and the back needle bed BB are L0.5. On the back needle bed BB, the base structure is knitted in a 1-stitch skipping-1-stitch manner. The starting point loop of the three-dimensional relief structure is constructed at the target position point on the base structure.

[0046] On the back needle bed, knit in a 1-skip-1-skip pattern, that is, knitting with 1 stitch coming up and 1 stitch not coming down in a horizontal cycle. When knitting with stitches coming up, the starting height is 3 / 4 to form a purl loop a. When knitting without stitches coming down, the starting height is 0, and a float is pulled. By following these 2-stitch horizontal minimum basic cycle units, the base structure of the weft plane purl loop a can be knitted.

[0047] When knitting rows ① and ②, the machine head with yarn guide y knits new loops. Odd-numbered needles (1st, 3rd, 5th, and 7th needles) knit reverse loop a, and even-numbered needles (2nd, 4th, 6th, and 8th needles) do not knit. Pull the float yarn b, and knit the base structure of the weft plane reverse loop in this horizontal cycle.

[0048] When knitting row ③, the machine head with yarn guide y knits a new loop, the back needle bed BB skips stitches at the 10th and 12th stitches and starts a new loop c, the front needle bed centerline 11th stitch skips stitches and starts a new loop d, the remaining loops are knitted in the same way as rows ① and ②.

[0049] When knitting the fourth row, the machine head with yarn guide y knits a new loop, the 10th and 12th needles of the front needle bed FB skipped stitches and started a new loop d, and the 11th needle of the center axis of the rear needle bed knits a reverse loop. The knitting pattern of the remaining loops is still the same as that of the first and second rows.

[0050] The starting point for constructing the three-dimensional relief knitted fabric: At the center axis position and the two adjacent empty needle positions to the left and right of the center axis, knit three stitches in total, alternating between the front and back needle bed loops for two rows. Specifically, in the first row, while knitting the front needle bed FB knit stitch along the center axis, knit the back needle bed BB purl stitch a at the adjacent empty needle positions to the left and right. In the second row, while knitting the back needle bed BB purl stitch a along the center axis, knit the front needle bed knit stitches at the adjacent empty needle positions to the left and right, thus forming the starting point loop for the three-dimensional relief. Move the purl stitch a of the 10th stitch of the back needle bed BB one stitch to the left and flip it to the empty needle position e of the 9th stitch of the front needle bed. This completes the starting point loop for the three-dimensional relief structure.

[0051] Step 2: On the skip stitch position of the purl stitch loop a, knit the knit stitch loop of the front needle bed FB and the purl stitch loop a of the back needle bed BB respectively according to the local short return, and the loops between the two needle beds do not flip each other, to knit a three-dimensional relief structure.

[0052] A three-dimensional relief structure is created using multi-layer knitting, holding the horizontal rows, fixing the central axis, and increasing / decreasing stitches. The three-dimensional relief structure has a double-layered cylindrical structure on each side of the central axis.

[0053] Step 21: On the reverse stitch loop a of the base structure, with the help of the three empty needle points of the back needle bed BB relative to the needle bed and the skipped needle position front needle bed FB and back needle bed BB, each loop of the front needle bed FB and back needle bed BB is gradually transferred to both sides, so that the double-layer cylindrical structure floats on the fabric surface and gradually extends outward.

[0054] like Figure 3 The image shown is a plan view of the first band braided control structure of the present invention.

[0055] The machine head with yarn guide y moves from left to right. Odd-numbered needles 1, 3, 5, 7, 9, and 11 knit reverse loop a, while even-numbered needles 2, 4, 6, 8, and 10 are not knitted. Float yarn b is pulled, and yarn guide y stops at the 11th needle position on the center line. Next, the loop at the empty needle position e of the 9th needle on the front needle bed FB is moved one needle position to the right and flipped to the 10th needle position on the back needle bed. The yarn guide is kicked back, and a new loop is knitted for the 10th needle on the front needle bed FB; the yarn guide is kicked back, and new loops are knitted for the 10th and 12th needles on the back needle bed BB, and a new loop is knitted for the 11th needle on the front needle bed FB; the yarn guide is kicked back, and a new loop is knitted for the 12th needle on the front needle bed FB, at which point the yarn guide stops at the 12th needle position. Then, the loop f of the 12th needle on the back needle bed is moved one needle position to the right and flipped to the 13th needle position on the front needle bed. Finally, continue knitting the back needle bed BB with the yarn guide, using the odd-numbered needles 13, 15, 17, 19, and 21 reverse loops a, and leaving the even-numbered needles 14, 16, 18, and 20 unknitted, pulling the float yarn b, to complete the knitting of the first wave control structure.

[0056] like Figure 4 The image shown is a plan view of the second-band braided control structure in this invention.

[0057] The machine head with yarn guide y moves from right to left. Odd-numbered needles 21, 19, 17, 15, 13, and 11 knit reverse loop a, while even-numbered needles 20, 18, 16, 14, and 12 are left unknitted and the float yarn b is pulled. At this point, yarn guide y stops at the center line (11th needle). Next, the loop of the 13th needle on the front needle bed is moved one needle position to the left and flipped to the 12th needle position on the back needle bed. Yarn guide y is kicked back, and a new loop is knitted for the 12th needle on the front needle bed FB; yarn guide y is kicked back again, and new loops are knitted for the 10th and 12th needles on the back needle bed BB, and a new loop is knitted for the 11th needle on the front needle bed FB. At this point, the yarn guide stops at the 10th needle position. Next, move the loop of the 12th stitch of the back needle bed BB one stitch to the right and flip it to the 13th stitch of the front needle bed FB. Then, move the loop of the 13th stitch of the front needle bed one stitch to the right and flip it to the 14th stitch of the back needle bed BB. Flip the loop of the 12th stitch of the front needle bed FB to the 12th stitch of the back needle bed BB. Then, move the loop of the 12th stitch of the back needle bed two stitches to the right and flip it to the 14th stitch of the front needle bed. Kick back the yarn guide and knit a new loop for the 10th stitch of the front needle bed. At this point, the yarn guide stops at the 10th stitch position. Next, move the loop of the 10th stitch of the back needle bed one stitch to the left and flip it to the front needle bed position of the 9th stitch; then, move the loop of the 9th stitch of the front needle bed one stitch to the left and flip it to the back needle bed position of the 8th stitch; flip the loop of the 10th stitch of the front needle bed to the back needle bed position t; then, move the loop of the 10th stitch of the back needle bed two stitches to the left and flip it to the front needle bed position of the 8th stitch; finally, move the loop of the 8th stitch of the back needle bed one stitch to the right and flip it to the front needle bed position of the 9th stitch. Finally, continue knitting the back needle bed odd-numbered stitches 9, 7, 5, 3, 1 (reverse stitches a), and leave the even-numbered stitches 8, 6, 4, 2 unknitted, pulling the float b, to complete the knitting of the second wave control structure.

[0058] By following the steps above, the first and second bands are arranged in a horizontal cyclic arrangement for localized return weaving and the front and rear beds are moved separately, so that the three-dimensional structure coils are wrapped around each other, and the double-layer cylindrical structure with outward moving coils can be woven.

[0059] After the above structure is woven, the double-layer cylindrical structure is further moved inward.

[0060] Step 22: On the reverse stitch loop a of the base structure, with the help of the three empty needle points of the back needle bed BB relative to the needle bed and the skipped needle position front needle bed FB and back needle bed BB, each loop of the front needle bed FB and back needle bed BB is gradually transferred towards the central axis, so that the double-layer cylindrical structure floats on the fabric surface and gradually gathers inward.

[0061] like Figure 5 The image shown is a plan view of the fourth-band braided control structure in this invention.

[0062] The machine head with yarn guide y moves from left to right. Odd-numbered needles 1, 3, 5, 7, 9, and 11 are knitted as reverse loops a, while even-numbered needles 2, 4, 6, 8, and 10 are left unknitted and the float yarn b is pulled. At this point, yarn guide y stops at the center line (11th needle). Next, the loops of needles 7 and 9 on the front needle bed FB are moved one needle position to the right and flipped to the back needle bed BB position (needles 8 and 10). Yarn guide y is kicked back, and new loops are knitted for needles 10 and 8 on the front needle bed FB. Yarn guide y is kicked back, and new loops are knitted for needles 8, 10, 12, and 14 on the back needle bed BB and a new loop for needle 11 on the front needle bed FB. Yarn guide y is kicked back, and new loops are knitted for needles 14 and 12 on the front needle bed FB. At this point, yarn guide y stops at the 12th needle position. The loops of needles 12 and 14 on the back needle bed BB are moved one needle position to the right and flipped to the front needle bed FB position (needles 13 and 15). Finally, the yarn guide y continues to knit the back needle bed BB, with odd-numbered needles 13, 15, 17, 19, and 21 reverse loops a, and even-numbered needles 14, 16, 18, and 20 left unknitted and the float yarn b pulled, completing the knitting of the fourth wave control structure before the end of the inward shift.

[0063] like Figure 6 The image shown is a plan view of the third-band braided control structure of the present invention.

[0064] The machine head with yarn guide y moves from right to left. Odd-numbered needles 21, 19, 17, 15, 13, and 11 knit reverse loop a, while even-numbered needles 20, 18, 16, 14, and 12 are left unknitted and the float yarn b is pulled. At this point, yarn guide y stops at the 11th needle position on the center line. Move the loops of the 13th and 15th needles on the front needle bed FB one needle position to the left and flip them to the 12th and 14th needles on the back needle bed BB. Kick back yarn guide y and knit new loops of the 12th and 14th needles on the front needle bed FB. Kick back yarn guide y and knit new loops of the 12th and 10th needles on the back needle bed BB and a new loop of the 11th needle on the front needle bed FB. At this point, yarn guide y stops at the 10th needle position. Next, move the loop of stitch 13 on the front needle bed FB one stitch to the left and flip it to the back needle bed BB position (stitch 12). Move the loop of stitch 14 on the back needle bed BB one stitch to the left and flip it to the front needle bed FB position (stitch 13). Flip the loop of stitch 14 on the front needle bed FB to the back needle bed BB position (stitch 14). Then move the loop of stitch 14 on the back needle bed BB two stitches to the left and flip it to the front needle bed FB position (stitch 12). Kick back the yarn guide y and knit new loops for stitches 8 and 10 on the front needle bed FB; at this point, the yarn guide y stops at the 10th stitch position. Next, move the loop of the 8th stitch of the back needle bed BB one stitch to the right and flip it to the position of the 9th stitch on the front needle bed FB; move the loop of the 9th stitch of the front needle bed FB one stitch to the right and flip it to the position of the 10th stitch on the back needle bed BB; flip the loop of the 8th stitch of the front needle bed FB to the 8th stitch on the back needle bed BB, then move the loop of the 8th stitch of the back needle bed BB two stitches to the right and flip it to the position of the 10th stitch on the front needle bed FB; move the loop of the 10th stitch of the back needle bed BB one stitch to the left and flip it to the position of the 9th stitch on the front needle bed FB. Finally, the yarn guide y continues to knit the odd-numbered stitches 9, 7, 5, 3, 1 purl stitches a on the back needle bed BB, and does not knit the even-numbered stitches 8, 6, 4, 2, pulling the float b, completing the knitting of the third wave control structure before the end of the inward shift.

[0065] like Figure 7 The image shown is a plan view of the second-band braided control structure of the present invention.

[0066] The machine head with yarn guide y moves from left to right. Odd-numbered needles 1, 3, 5, 7, 9, and 11 knit reverse loop a, while even-numbered needles 2, 4, 6, 8, and 10 are left unknitted and the float yarn b is pulled. At this point, yarn guide y stops at the 11th needle position on the center line. Next, the loop of the 9th needle on the front needle bed FB is moved one needle position to the right and flipped to the 10th needle position on the back needle bed BB. Yarn guide y is kicked back, and a new loop is knitted for the 10th needle on the front needle bed FB. Yarn guide y is kicked back, and new loops are knitted for the 10th and 12th needles on the back needle bed BB and the 11th needle on the front needle bed FB. Yarn guide y is kicked back, and a new loop is knitted for the 12th needle on the front needle bed FB. At this point, yarn guide y stops at the 12th needle position. The loop of the 12th needle on the back needle bed BB is moved one needle position to the right and flipped to the 13th needle position on the front needle bed FB. Finally, the yarn guide y continues to knit the back needle bed BB, with odd-numbered needles 13, 15, 17, 19, and 21 reverse loops a, and even-numbered needles 14, 16, 18, and 20 left unknitted and the float yarn b pulled, completing the knitting of the second wave control structure before the end of the inward shift.

[0067] like Figure 8 The image shown is a plan view of the first band braided control structure of the present invention.

[0068] The machine head with yarn guide y moves from right to left. Odd-numbered needles 21, 19, 17, 15, 13, and 11 knit reverse loop a, while even-numbered needles 20, 18, 16, 14, and 12 are left unknitted and the yarn is pulled up (b). At this point, yarn guide y stops at the 11th needle position on the center line. Next, the loop of the 13th needle on the front needle bed FB is moved one needle position to the left and flipped to the 12th needle position on the back needle bed BB. Yarn guide y is kicked back, and a new loop is knitted for the 12th needle on the front needle bed FB. Yarn guide y is kicked back, and new loops are knitted for the 12th and 10th needles on the back needle bed BB and a new loop for the 11th needle on the front needle bed FB. At this point, yarn guide y stops at the 10th needle position. The loop of the 12th needle on the front needle bed FB is moved one needle position to the left and flipped to the 11th needle position on the center line. From position BB on the back needle bed, move the loop of the 12th stitch of the back needle bed BB one stitch to the left and flip it to position FB on the front needle bed, which is the 11th stitch on the center axis. Kick back the yarn guide y and knit a new loop for the 10th stitch of the front needle bed FB. Move the loop of the 10th stitch of the front needle bed FB one stitch to the right and flip it to position BB on the back needle bed, which is the 11th stitch on the center axis. Then, move the loop of the 10th stitch of the back needle bed BB one stitch to the right and flip it to position FB on the front needle bed, which is the 11th stitch on the center axis. Finally, continue knitting the back needle bed BB with yarn guide y. For odd-numbered stitches 9, 7, 5, 3, 1, purl loop a; for even-numbered stitches 8, 6, 4, 2, do not knit; pull the float yarn b. This completes the first wave control structure before the inward shift ends.

[0069] Thus, by repeating the above steps, a three-dimensional relief knitted structure with a separate double-layer cylindrical structure is completed, which is based on the base structure of the weft plane reverse stitch loops.

[0070] Step 23: Flip the 1 front needle bed FB knit loop on the center line back to the back needle bed BB, and integrate it with the base structure purl loop a to finish knitting.

[0071] like Figure 9 The image shown is a woven photograph of the three-dimensional relief effect knitted fabric of the present invention.

[0072] The three-dimensional relief knitted structure has the characteristics of three-dimensional protrusion and distinct layers.

[0073] This invention changes the traditional manual sewing design and production method in the industry, improving production efficiency and meeting product development needs without increasing production costs or processes. Appropriate modifications can be made within the scope of the invention's intent. It is suitable for knitting coarse or fine knitted fabrics on various machine types. Furthermore, it allows for the modification of the three-dimensional relief structure's shape, such as squares, circles, ovals, rhombuses, triangles, pentagons, and other geometric shapes, resulting in a more diversified range of three-dimensional relief structure shapes. Applying this knitting method to the design of knitted garments and apparel products can yield excellent results.

[0074] The terminology used in this invention is descriptive and exemplary, not restrictive. Since this invention can be embodied in many forms without departing from the spirit or essence of the technical solution, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
