Description

Technical Field

[0001] The present invention relates to the technical field related to knitting processing, and in particular to a high-speed and efficient knitting method suitable for a fully-formed one-piece garment process for a wool sweater, in which the front and back body pieces (front and back sleeve pieces) can be knitted with different yarns and the front and back pieces have different colors or different materials. Background Art

[0002] The process of fully-formed one-piece ready-made wool sweater can be completed in one go, eliminating manual processes such as cuff sewing. The utilization rate of wool yarn raw materials can reach almost 100%. While being highly efficient, it also makes a positive contribution to reducing resource waste and achieving sustainable development. Since the process of fully-formed one-piece ready-made garments is to knit the whole piece together at the same knitting position to knit the front and back pieces at the same time, the front and back pieces (front and back) are usually knitted using the same yarn mouth (the same yarn). In some products, the actual style of knitting the front and back pieces (front and back) with different yarns has been adopted, which improves the expressiveness of the product. The front and back pieces (front and back) must be connected on both sides of the knitted fabric when knitting with different yarns. The previous knitting method is: use the yarn mouth relatively forward to knit the back piece (back); use the yarn mouth relatively backward to knit the front piece (front); after each row of knitting of the front and back pieces (front and back) is completed, the two yarn mouths stay on the same side to form yarn entanglement, and use the yarn entangled with the front and back to connect the front and back pieces (front and back).

[0003] The existing publication number CN101545175A discloses a weaving method for a warp-knitted two-color jacquard seamless fabric, and the specific process flow is as follows: first, determine the basic weaving process, use one ground comb bar on each front and rear needle bed to weave the basic base fabric, and use two jacquard comb bars on each bed to weave the main jacquard pattern and the front and rear piece connecting structure; second, determine the main pattern padding yarn movement and corresponding jacquard needle action information formed by each jacquard comb, and combine the basic action information of the corresponding jacquard needle; finally, determine the padding yarn movement and jacquard needle action information of the front and rear garment edges, and use a superposition method.

[0004] The existing publication number CN101487164A discloses a weaving method for warp knitted jacquard seamless fabric, and the specific process flow is: first determine the basic weaving process. For general warp knitted seamless jacquard fabric, the front and rear needle beds each use a ground comb bar to weave the basic base fabric, and each use a jacquard comb bar to weave the main jacquard pattern and the front and rear piece connecting structure; secondly, determine the main pattern padding movement formed by the jacquard comb and the corresponding jacquard needle action information; finally, determine the padding movement of the front and rear garment edges and the jacquard needle action information.

[0005] The above disclosed editing method is characterized by a simple structure. However, each time a row of front and back pieces (front and back) is knitted, there is an empty run of the machine head, and the empty run of the machine head without knitting also consumes the overall knitting time. Therefore, the biggest disadvantage is that a large number of empty runs of the machine head will be generated when knitting the entire knitted fabric, thereby reducing the knitting efficiency of the entire product. Summary of the invention

[0006] In view of the shortcomings of the prior art, the above technical problems of the present invention are mainly solved by the following technical solutions: A method for connecting the front and rear panels of a fully molded product, comprising the following steps: Step 1: Use the first yarn feeder to knit the first row of the back body from left to right (5a). After knitting, the yarn feeder stops on the right side. Step 2: Use the needle transfer system to transfer one needle on each side of the back body piece to the front lower needle bed; Step 3: Use the first yarn feeder to knit the second row of the back body from right to left (5b), and at the same time, knit one needle on each side on the front lower needle bed. After knitting, the yarn feeder returns to the left side; Step 4: Use the second yarn feeder to knit the first row of the front piece to the right (5c). After knitting, the yarn feeder stops on the right side. Step 5: Use the needle transfer system to transfer one needle on each side of the front lower needle bed to the rear lower needle bed; Step 6: Use the second yarn mouth to knit the second row of the front piece to the left (5d). At this time, one needle is placed on each of the left and right loops on the lower back needle bed, so that the yarn from the first yarn mouth and the loops produced by the second yarn mouth are entangled to form a woven fabric. After knitting, the yarn mouth returns to the left.

[0007] Preferably, the first yarn mouth and the second yarn mouth are different yarn mouths; the first yarn mouth is a No. 6 yarn mouth with a machine head; and the second yarn mouth is a No. 4 yarn mouth with a machine head.

[0008] Preferably, the needle transfer system is a needle transfer system on a fully formed flat knitting machine.

[0009] Preferably, the steps one to six are repeated to form a longitudinally extended braided fabric.

[0010] A fabric comprises front and back panels, wherein the front and back panels are connected by the fully molded front and back panel connecting method according to any one of claims 1 to 3.

[0011] A method for connecting fully formed front and rear panels, wherein the knitting time calculation formula of the knitted fabric is: T=4 (times)*L / V; wherein V is the moving speed of the machine head; and L is the knitting width.

[0012] The present invention can achieve the following effects: The present invention provides a method for connecting fully-formed front and back pieces. The method utilizes a needle transfer system on a fully-formed flat knitting machine to connect the front and back pieces while knitting them, thereby eliminating the need for the machine head to run idle in the traditional method, thereby improving the knitting efficiency. Furthermore, there is no need to consider the front and back yarn mouth positions when knitting the front and back pieces, and the yarn mouths can be freely arranged in complex style designs.

Embodiment 4

[0022] In this embodiment, the front and back pieces are knitted with different yarns, the front piece is made of red wool yarn, and the back piece is made of blue acrylic yarn. During the knitting process, the back piece is knitted with the first yarn mouth, and the front piece is knitted with the second yarn mouth. The specific steps are as follows: A method for connecting the front and back pieces of a fully molded garment comprises the following steps: Step 1: Knit the first row of the back piece from left to right with the first yarn feeder (see Figure 6 5a) (in this example, the first yarn feeder is used, but any yarn feeder can be used as mentioned above) after knitting is completed, the yarn feeder stops on the right side; Step 2: In the same knitting row mentioned above, use the needle transfer system to transfer one needle on each side of the back body piece to the front lower needle bed; Step 3: Knit the second row of the back piece from right to left with the first yarn feeder (see Figure 6 5b), at the same time, one needle on each side is knitted on the front lower needle bed. The two needles knitted on each side on the front lower needle bed are reverse needles relative to the back piece. After knitting, the yarn feeder returns to the left side; Step 4: The second yarn feeder weaves the first row of the front piece to the right (attached Figure 6 5c) (in this example, the second yarn feeder is used, but any yarn feeder can be used as mentioned above) After knitting is completed, the yarn feeder stops on the right side; Step 5: In the same knitting row mentioned above, use the needle transfer system to transfer one stitch of each loop on the front lower needle bed on the left and right sides to the rear lower needle bed; Step 6: The second yarn feeder weaves the second row of the front piece to the left (attached Figure 6 5d in the figure), at this time, one needle on each side of the left and right loops is placed on the lower back needle bed so that the yarn of the second yarn mouth and the loops generated by the yarn of the first yarn mouth are entangled to form a knitted fabric (see Appendix Figure 4 4c and 4d in the figure), the front and rear fabric pieces are connected by this entanglement, and the yarn feeder returns to the left side after the knitting is completed; Repeat the above steps to weave repeatedly to form a longitudinally extended braided fabric.

[0023] Comparative Example: Traditional braiding connection method: The braiding process is as follows (refer to the head travel trajectory diagram, attached Figure 2 ) Step 1: When knitting the front and back pieces (front and back), the yarn feeder should stop at the left side of the fabric; use the yarn feeder that is relatively close to the front to knit the back piece (back) to the right, refer to the attached Figure 2 2a; the nose of the aircraft returns to the left side without any movement. Please refer to the attached Figure 2 Middle 2b: Use the yarn feeder at the back to knit the front piece (front) to the right, Figure 2 2c; (At this time, the two yarn feeders stay on the right side, forming a yarn entanglement on the right side); use the relatively forward yarn feeder to knit the back piece (back) to the left, refer to the attached Figure 2 2d; the nose of the aircraft returns to the right side without any movement. Figure 2 Middle 2e; Use the yarn feeder at the back to knit the front piece (front) to the left, Figure 2 Middle 2f; (At this time, the two yarn feeders stay on the left side, forming yarn entanglement on the left side). Therefore, the traditional method is characterized by a simple structure, but there is an empty run of the machine head for each row of front and back pieces (front and back). The empty run of the machine head without knitting also consumes the overall knitting time.

[0024] The calculation formula for the braiding time of the traditional braiding connection method is: T (traditional) = 6 (times) * L / V; Obviously, under the conditions of weaving the same width and the same machine head moving speed, T (traditional) is 6 / 4 of T (present invention), that is, 1.5 times. Therefore, the weaving method of the present invention can improve the weaving efficiency by 50%.

[0025] Two examples: 1. Women's vest Weaving width: 65cm; Head speed: 0.9 m / s 2. Men's pullover Weaving width: 122cm (including sleeves) Head speed: 0.8 m / s; Women's vest; if calculated according to the traditional formula: T (traditional) = 6 (times) * L / V; L is 65 cm; 0.9 m / s; T (traditional) = 6*0.65 m / 0.9 m / s = 4.33 seconds; T (this technique) = 4*0.65 m / 0.9 m / s = 2.88 seconds; Men's pullover; if calculated according to the traditional formula: T (traditional) = 6 (times) * L / V; L is 122 cm; 0.8 m / s; T (traditional) = 6*1.22m / 0.8m / s = 9.15 s; T (this technology) = 4*1.22m / 0.8m / s = 6.1 s; Therefore, the weaving efficiency can be improved by 50% by using the weaving method of the present invention.

[0026] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the essential features of the invention. The embodiments should therefore be considered in all respects as exemplary and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations within the meaning and range of equivalents of the claims be included in the invention.

[0027] In summary, the above description is only a specific embodiment of the present invention, but the structural features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
