Abstract
Description
Technical Field
[0001] This invention relates to the field of weaving technology, and specifically to a multi-color cut loop pile high-density weaving process. Background Technology
[0002] A cut-loop pile machine is a device that cuts loops in textiles to create a pile-like surface. In existing cut-loop pile weaving processes, to ensure a strong pile, a loop yarn, a binding yarn, and a base yarn are typically fed into a weaving group. The needle pulls the loop yarn down to form loops, and the binding and base yarns then bind the loop yarn tightly, preventing the pile formed after cutting from falling off. While this weaving process achieves the effect of preventing pile falloff, the resulting pile surface is not dense enough, resulting in insufficient comfort and aesthetics. Furthermore, existing cut-loop pile machines make it difficult to adjust the patterns and colors of the fabrics produced, hindering the rapid changes in fabric products. Therefore, how to provide a high-density, multi-color cut-loop pile weaving process is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0003] To overcome the shortcomings of the existing technology, the present invention provides a high-density multicolor cut loop pile weaving process with high pile density and easy adjustment of pattern and color.
[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a multi-color cut-loop pile high-density weaving process.
[0005] There are three types of stitches: stitch a, stitch b, and stitch c. The stitches are driven by the lower triangle group, and the stitches are arranged in a cycle of stitch a, stitch b, and stitch c.
[0006] There are three types of knitting groups: the first knitting group, the second knitting group, and the third knitting group. Each knitting group is equipped with a lower triangle group, a first terry needle selector, a second terry needle selector, and a loop cutter needle selector. The lower triangle group includes a pulling triangle track and a loop cutter track. The first terry needle selector and the second terry needle selector correspond to the pulling triangle track, and the loop cutter needle selector corresponds to the loop cutter track.
[0007] The first weaving group, the second weaving group, and the third weaving group are arranged in a cyclical pattern.
[0008] When the stitch passes through the first knitting group:
[0009] Only the needle a can be driven by the loop-pulling triangle trajectory. The first loop selector controls whether the needle a performs the first yarn feeding and loop-pulling action, and the second loop selector controls whether the needle a performs the second yarn feeding and loop-pulling action. If the needle a performs the first yarn feeding action, it will not perform the second yarn feeding action, and if the needle a performs the second yarn feeding action, it will not perform the first yarn feeding action. The loop-cutting needle selector ensures that only the needle b is driven by the loop-cutting triangle trajectory to perform the loop-cutting action.
[0010] When the stitch passes through the second knitting group:
[0011] Only the needle b can be driven by the loop-pulling triangle trajectory. The first loop selector controls whether the needle b performs the first yarn feeding and loop-pulling action, and the second loop selector controls whether the needle b performs the second yarn feeding and loop-pulling action. If the needle b performs the first yarn feeding action, it will not perform the second yarn feeding action, and if the needle b performs the second yarn feeding action, it will not perform the first yarn feeding action. The loop-cutting needle selector ensures that only the needle c is driven by the loop-cutting triangle trajectory to perform the loop-cutting action.
[0012] When the knitting needle passes through the third knitting group:
[0013] Only the needle c can be driven by the loop-pulling triangle trajectory. The first loop selector controls whether the needle c performs the first yarn feeding and loop-pulling action, and the second loop selector controls whether the needle c performs the second yarn feeding and loop-pulling action. If the needle c performs the first yarn feeding action, it will not perform the second yarn feeding action, and if the needle c performs the second yarn feeding action, it will not perform the first yarn feeding action. The loop-cutting needle selector ensures that only the needle a is driven by the loop-cutting triangle trajectory to perform the loop-cutting action.
[0014] The loop-cutting action performed in the first knitting group corresponds to cutting the loops knitted in the second knitting group of the previous round; the loop-cutting action performed in the second knitting group corresponds to cutting the loops knitted in the third knitting group of the previous round; the loop-cutting action performed in the third knitting group corresponds to cutting the loops knitted in the first knitting group of the previous round; the loops are locked after being knitted by two sets of knitting actions before the cutting action is performed, so that the pile is firmly secured and not easy to fall apart.
[0015] Furthermore, the napping triangle track includes a first start-up track, a first high nap track, a first low nap track, a second start-up track, a second high nap track, and a second low nap track; the knitting group is also equipped with a first high / low nap needle selector and a second high / low nap needle selector, the first high / low nap needle selector being located after the first terry needle selector, and the second high / low nap needle selector being located after the second terry needle selector.
[0016] If the needle is not screened out after passing through the first loop needle selector, it will rise through the first starting track and take in the yarn. Then, it will be controlled by the first high and low loop needle selector to either descend through the first high loop track to pull the yarn into a high loop or descend through the first low loop track to pull the yarn into a low loop.
[0017] If the yarn is not screened out after passing the second loop needle selector, it will rise along the second starting track and take yarn two. Then, it will be controlled by the second high-low loop needle selector to either descend along the second high loop track to pull yarn two down into a high loop, or descend along the second low loop track to pull yarn two down into a low loop.
[0018] Furthermore, it also includes several reset triangles, each of which is located in front of the first terry needle selector, the second terry needle selector, and the terry cut needle selector.
[0019] Furthermore, one of the two yarns fed into the first weaving group, one of the two yarns fed into the second weaving group, and one of the two yarns fed into the third weaving group are of the same color.
[0020] Furthermore, there are three types of purl needles: purl needle I, purl needle II, and purl needle III, which are driven by the upper triangle group. The purl needles are arranged in a cycle of purl needle I, purl needle II, and purl needle III.
[0021] The upper triangular group includes a first needle exit trajectory, a second needle exit trajectory, and a third needle exit trajectory. The upper needle I is driven by the first needle exit trajectory, the upper needle II is driven by the second needle exit trajectory, and the upper needle III is driven by the third needle exit trajectory.
[0022] The knit stitch I corresponds to the knit stitch a in the vertical position; the knit stitch II corresponds to the knit stitch b in the vertical position; and the knit stitch III corresponds to the knit stitch c in the vertical position.
[0023] When the purl needle passes through the first knitting group:
[0024] Knitting I is a plain stitch that passes without the needle going through. Knitting II and Knitting III simultaneously perform the following actions in sequence: yarn feeding one, yarn holding, yarn feeding two, and yarn unwinding and binding.
[0025] When the purl needle passes through the second knitting group:
[0026] Purl II is a plain stitch that does not exit the needle. Purl I and Purl III simultaneously perform the following actions in sequence: yarn feeding one, yarn holding, yarn feeding two, and yarn unwinding and binding.
[0027] When the purl needle passes through the third knitting group:
[0028] Knitting III is a plain stitch that passes without the needle. Knitting III and Knitting I synchronously perform the following actions in sequence: yarn feeding one, yarn holding, yarn feeding two, and yarn unwinding and binding.
[0029] As can be seen from the above description of the present invention, compared with the prior art, the multi-color cut loop pile high-density knitting process provided by the present invention has the following advantages:
[0030] Two yarns, yarn one and yarn two, are fed into a knitting group and are tightly bound together. Compared with the traditional process of feeding three yarns (terry yarn, binding yarn, and base yarn), this application only feeds two yarns, eliminating one horizontal row, thus significantly increasing the pile density.
[0031] The weaving process uses a loop-cutting technique, where the yarn forming the loops is cut in the next round of weaving. At this time, the loops have been reinforced and locked by the two sets of weaving groups in the previous round, thus ensuring the firmness of the yarn weaving and preventing the cut pile from falling off easily.
[0032] Within the knitting group, the needle can be selected to take yarn one, yarn two, or no yarn. If it takes yarn, it can also be selected to pull the pile high or low. The action control of the needle is realized by the needle selector, which is easy to modify and adjust. Therefore, this process can knit fabrics with free combination of high pile, low pile, and no pile, and the pile pattern is diverse.
[0033] In each of the three weaving groups, one of the two yarns fed in is the same color, while the other yarn can be changed to a different color. By changing the color of the fed yarn, multi-color mixed weaving can be achieved, resulting in a variety of pile patterns. Attached Figure Description

Detailed Implementation
[0039] The present invention will be further described below through specific embodiments.
[0040] Reference Figures 1 to 4 As shown, a multi-color cut loop pile high-density weaving process includes:
[0041] There are three types of needles: needle I, needle II, and needle III. They are driven by an upper triangular group. The needles are arranged in a cyclical pattern of needle I, needle II, and needle III. The upper triangular group includes a first needle exit trajectory 11, a second needle exit trajectory 12, and a third needle exit trajectory 13. Needle I is driven by the first needle exit trajectory, needle II is driven by the second needle exit trajectory, and needle III is driven by the third needle exit trajectory.
[0042] There are three types of knitting needles: knitting needle a, knitting needle b, and knitting needle c. The knitting needles are driven by the lower triangle group. The knitting needles are arranged in a cycle of knitting needle a, knitting needle b, and knitting needle c. The knitting needles include the jacquard hook, the center needle, and the jacquard piece.
[0043] The knit stitch I corresponds to the knit stitch a in the vertical position, the knit stitch II corresponds to the knit stitch b in the vertical position, and the knit stitch III corresponds to the knit stitch c in the vertical position.
[0044] There are three types of knitting groups: the first knitting group, the second knitting group, and the third knitting group. Each knitting group is equipped with a lower triangular group, a first terry needle selector 21, a second terry needle selector 22, and a loop cutter needle selector 23. The lower triangular group includes a napping triangular track 3 and a loop cutter triangular track 4. The first terry needle selector 21 and the second terry needle selector 22 correspond to the napping triangular track 3, and the loop cutter needle selector 23 corresponds to the loop cutter triangular track 4. It also includes a yarn pressing wheel, which is located at the loop cutter triangular track 4.
[0045] The first weaving group, the second weaving group, and the third weaving group are arranged in a cyclical pattern.
[0046] When the stitch passes through the first knitting group:
[0047] Knitting I is a plain stitch that passes without the needle going through. Knitting II and Knitting III simultaneously perform the following actions in sequence: yarn feeding one, yarn holding, yarn feeding two, and yarn unwinding and binding.
[0048] Only the needle a can be driven by the loop-pulling triangle trajectory 3. The first loop needle selector 21 controls whether the needle a performs the first yarn feeding and loop-pulling action. The second loop needle selector 22 controls whether the needle a performs the second yarn feeding and loop-pulling action. If the needle a performs the first yarn feeding action, it will not perform the second yarn feeding action. If the needle a performs the second yarn feeding action, it will not perform the first yarn feeding action. The loop-cutting needle selector 23 ensures that only the needle b is driven by the loop-cutting triangle trajectory 4 to perform the loop-cutting action.
[0049] When the stitch passes through the second knitting group:
[0050] Purl II is a plain stitch that does not exit the needle. Purl I and Purl III simultaneously perform the following actions in sequence: yarn feeding one, yarn holding, yarn feeding two, and yarn unwinding and binding.
[0051] Only the needle b can be driven by the loop-pulling triangle trajectory 3. The first loop needle selector 21 controls whether the needle b performs the first yarn feeding and loop-pulling action, and the second loop needle selector 22 controls whether the needle b performs the second yarn feeding and loop-pulling action. If the needle b performs the first yarn feeding action, it will not perform the second yarn feeding action, and if the needle b performs the second yarn feeding action, it will not perform the first yarn feeding action. The loop-cutting needle selector 23 ensures that only the needle c is driven by the loop-cutting triangle trajectory 4 to perform the loop-cutting action.
[0052] When the knitting needle passes through the third knitting group:
[0053] Knitting III is a plain stitch that passes without the needle. Knitting III and Knitting I synchronously perform the following actions in sequence: yarn feeding one, yarn holding, yarn feeding two, and yarn unwinding and binding.
[0054] Only the needle c can be driven by the loop-pulling triangle trajectory 3. The first loop needle selector 21 controls whether the needle c performs the first yarn feeding and loop-pulling action, and the second loop needle selector 22 controls whether the needle c performs the second yarn feeding and loop-pulling action. If the needle c performs the first yarn feeding action, it will not perform the second yarn feeding action, and if the needle c performs the second yarn feeding action, it will not perform the first yarn feeding action. The loop-cutting needle selector 23 ensures that only the needle a is driven by the loop-cutting triangle trajectory 4 to perform the loop-cutting action.
[0055] The loop-cutting action performed in the first knitting group corresponds to cutting the loops knitted in the second knitting group of the previous round; the loop-cutting action performed in the second knitting group corresponds to cutting the loops knitted in the third knitting group of the previous round; the loop-cutting action performed in the third knitting group corresponds to cutting the loops knitted in the first knitting group of the previous round; the loops are locked after being knitted by two sets of knitting actions before the cutting action is performed, so that the pile is firmly secured and not easy to fall apart.
[0056] The napping triangle track 3 includes a first start-up track 31, a first high-pile track 32, a first low-pile track 33, a second start-up track 34, a second high-pile track 35, and a second low-pile track 36; the knitting group also includes a first high-low pile needle selector 24 and a second high-low pile needle selector 25, with the first high-low pile needle selector 24 located after the first terry needle selector 21 and the second high-low pile needle selector 25 located after the second terry needle selector 22; it also includes several reset triangles, each reset triangle being located in front of the first terry needle selector, in front of the second terry needle selector, and in front of the loop cut needle selector, respectively.
[0057] If the needle is not screened out after passing through the first loop needle selector 21, it will rise through the first starting track 31 and take in the yarn. Then, it will be controlled by the first high and low loop needle selector 24 to descend through the first high loop track 32 to pull the yarn into a high loop, or descend through the first low loop track 33 to pull the yarn into a low loop.
[0058] If the yarn is not screened out after passing the second loop needle selector 22, it will rise through the second starting track 34 and take yarn two. Then, it will be controlled by the second high and low loop needle selector 25 to descend through the second high loop track 35 to pull yarn two down into a high loop, or descend through the second low loop track 36 to pull yarn two down into a low loop.
[0059] One of the two yarns fed into the first weaving group, one of the two yarns fed into the second weaving group, and one of the two yarns fed into the third weaving group are of the same color.
[0060] Two yarns, yarn one and yarn two, are fed into each knitting group. If yarn one forms a loop, it is tied tightly with yarn two; if yarn two forms a loop, it is tied tightly with yarn one. Compared to the traditional process of feeding three yarns (loop yarn, binding yarn, and base yarn), this application only feeds two yarns, eliminating one row, thus significantly increasing the pile density. Further design of the knitting process enables loop cutting every other round. The yarn forming the loop is only cut in the next knitting round. By this time, the loop has already been reinforced and locked by the two knitting groups in the previous round, ensuring the strength of the yarn knit and preventing the cut pile from easily shedding.
[0061] In the knitting group:
[0062] If the needle emerges from the first starting track 31 and takes one thread, choose either the first high-pile track 32 to raise the loop or the first low-pile track 33 to lower the loop; if the needle emerges from the second starting track 34 and takes two threads, choose either the second high-pile track 35 to raise the loop or the second low-pile track 36 to lower the loop; if the needle does not emerge, it corresponds to knitting a non-pilly fabric. The needle movement is controlled by a needle selector, which is easy to modify and adjust. Therefore, this process allows for the knitting of fabrics with free combinations of high-pile, low-pile, and non-pilly textures, resulting in a variety of pile patterns.
[0063] In each of the three weaving groups, one of the two yarns fed in is the same color, while the other yarn can be a different color. For example, if yarn one in all three weaving groups is white and yarn two is red, a two-color mixed weave can be achieved. If yarn one in the first and second weaving groups is white and yarn two is red, and yarn one in the third weaving group is white and yarn two is green, a three-color mixed weave can be achieved. If yarn one in the first weaving group is white and yarn two is red, yarn one in the second weaving group is white and yarn two is green, and yarn one in the third weaving group is white and yarn two is blue, a four-color mixed weave can be achieved. Therefore, this process can weave multi-color mixed weave fabrics with diverse pile patterns.
[0064] The above is only one specific embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept shall be considered as infringing the protection scope of the present invention.
