Description

Technical Field

[0001] This invention relates to the field of knitted fabrics, and more particularly to a horizontally knitted double-sided three-dimensional multi-channel fabric and its knitting method. Background Technology

[0002] With technological advancements and evolving user needs, the application areas of wearable smart devices are continuously expanding. Wearable smart devices typically include intelligent clothing, bags, accessories, carpets, curtains, and more. When configuring wearable smart devices, it's common to embed tubular components such as large-diameter, rigid wires, fiber batteries, and silicone tubes within the fabric. Currently, common installation methods include manually sewing the tubular components to the fabric, or sewing multiple pieces of fabric together to form multiple tubes, then inserting the tubular components into these tubes for fixation. However, both of these methods are complex, time-consuming, and suffer from issues such as insecure fixation and structural instability. Summary of the Invention

[0003] The problem solved by this invention is to provide a horizontally woven double-sided three-dimensional multi-channel fabric, which is a fabric with an integrally formed structure of multiple channels. It not only has aesthetic appeal, but also has a more stable structure, which can adapt to the built-in requirements of various tubular fittings and ensure the firmness of the fixation.

[0004] In a first aspect, the present invention provides a horizontally woven double-sided three-dimensional multi-channel fabric, characterized in that it is made of a composite of double-sided jacquard structure and raised stripe structure, wherein the double-sided jacquard structure includes a front and a back side with double-sided jacquard, and the raised stripe structure is distributed on the back side of the double-sided jacquard structure and forms a tubular channel with the front side of the double-sided jacquard structure.

[0005] Furthermore, the double-sided jacquard weave can employ sesame dot jacquard or horizontal stripe jacquard.

[0006] Furthermore, the raised rib structure includes continuous raised rib structure and localized raised rib structure.

[0007] Furthermore, the convex strip structure includes a transverse channel structure, a serpentine channel structure, or an oblique channel structure.

[0008] Secondly, the present invention provides a method for weaving a horizontally woven double-sided three-dimensional multi-channel fabric, which includes the following steps: S1. Use a double needle bed flat knitting machine to knit, and select 2 to 4 sets of yarn from 2 to 4 yarn guides on the machine to knit a double-sided jacquard structure on the front and back needle beds at the same time. The width of the double-sided jacquard structure fabric includes the total number of needles x. After knitting b rows, the yarn guide on the front needle bed stops knitting, where b is the number of interval rows of the ribbed structure. S2. Select at least one set of yarns on the yarn guide, and select a number of stitches from the total number of stitches x on the back of the double-sided jacquard structure on the back of the needle bed to continue knitting, knitting c rows of single-sided raised stripe structure, where a is the number of stitches knitted in the raised stripe structure and a≤x, and c is the number of rows of the raised stripe structure. S3. Repeat steps S1 and S2 above until a double-sided jacquard structure with y rows is completed, where y is the length of the double-sided jacquard structure, i.e. the number of rows of coils. The double-sided jacquard structure includes ((y / b)-1) convex strip structures.

[0009] Furthermore, in S2, only the back needle bed is woven with single-sided plain weft knitting containing c rows. The number of rows of single-sided plain weft knitting on the back needle bed differs from that on the front needle bed, causing the excess fabric to bulge backward and form a raised stripe structure.

[0010] Furthermore, in S2, only the back needle bed is knitted with 1+1 variation weft plain stitches containing c rows. The 1+1 variation weft plain stitches are knitted by the needles on the back needle bed using 1 float and 1 loop alternately, that is, two rows of knitting complete one pattern cycle. In the end, all the needles on the back needle bed participate in one loop and one float knitting action.

[0011] Furthermore, in S2, only the back needle bed is knitted with 2+1 variation weft plain stitches containing c rows. The 2+1 variation weft plain stitches are knitted by the needles on the back needle bed using 2 floats and 1 loop to interweave between three rows to complete a pattern cycle. In the end, all the needles on the back needle bed participate in 1 loop formation and 2 float knitting actions.

[0012] The beneficial effects of the horizontally woven double-sided three-dimensional multi-channel fabric of this invention are as follows: The fabric of this application is a composite structure combining double-sided jacquard and raised stripe structures, so that the front of the composite structure fabric has a pattern and the back has channels. It adopts a one-time forming weaving method, which simplifies the process. Moreover, the channel type of the raised stripe structure can be formed by combining different shaped structures to form horizontal, serpentine, and diagonal channels, etc., to meet different needs. In application, the corresponding tubular material accessories can be directly inserted through the raised stripe structure on the back to avoid the accessories being exposed and to play a protective role. At the same time, the extensibility of the knitted loop structure allows it to fit well with the tube wall, which can better fix the tube and make the fabric as a whole have a more stable structure. Furthermore, the channels on the back do not affect the pattern on the front, making it a channel covering fabric that combines concealment, protection, and fashion. Attached Figure Description

[0016] The present application will be further described below with reference to the accompanying drawings and embodiments.

[0017] Example 1, This embodiment discloses a horizontally woven double-sided three-dimensional multi-channel fabric, which is integrally formed by combining a double-sided jacquard structure and a raised stripe structure. The double-sided jacquard structure includes a front and a back side, and the raised stripe structure is distributed on the back side of the double-sided jacquard structure, forming a tubular channel with the front side. Tubular fittings can be inserted and fixed through this tubular channel. Compared with the prior art, which uses direct sewing of tubular fittings or splicing and sewing multiple pieces of fabric to form a channel, this application presents an integrally formed double-sided jacquard fabric. This fabric combines jacquard and raised stripe structures, allowing tubular fittings to be directly inserted into the raised stripe structure for fixation, resulting in better fixation, simplified processes, and improved work efficiency.

[0018] Example 2, This embodiment provides a knitting method for horizontally knitted double-sided three-dimensional multi-channel fabric. The method involves knitting the aforementioned horizontally knitted double-sided three-dimensional multi-channel fabric using a double-needle bed flat knitting machine. This double-needle bed flat knitting machine can be a multi-system double-needle bed computerized flat knitting machine with sinkers and a gauge of E=7.2. This multi-system double-needle bed computerized flat knitting machine includes a front needle bed, a rear needle bed, an S1 system, and an S2 system. Two to four yarn guides are selected to operate within different knitting systems. In this embodiment, three groups (A, B, C) of yarns corresponding to three yarn guides are used to knit a double-sided jacquard structure. Any one group of yarns (A, B, or C) is selected to knit different types of plain weft ribbed structures at the designed positions of the double-sided jacquard structure to form channels.

[0019] Specifically, with Figure 1 For the design drawing, the width of the double-sided jacquard fabric is x, where x is the total number of stitches across the fabric width, and y is the length of the double-sided jacquard fabric, i.e., the total number of loop rows. Select the jacquard pattern according to requirements; options include sesame dot jacquard or striped jacquard, etc., and then set the raised stripes according to the channels to be inserted into the material. Figure 1 The width of each short-spaced solid line (a raised stripe) is a, where a is the number of stitches involved in weaving a single raised stripe, and a≤x. b is the distance between two raised stripes, i.e., the number of interval rows. The number of rows of raised stripes c is set according to the diameter of the set channel. Due to machine limitations, c≤12. The number of raised stripes in this fabric is ((y / b)-1).

[0020] The weaving method for this horizontally woven double-sided three-dimensional multi-channel fabric includes the following steps: S1. Before knitting, first thread three types of yarn, A, B, and C, into three yarn guides respectively. The three sets of yarns can be of the same type or different. It is preferable to use durable, soft, and easy-to-weave polyester or nylon yarns. Select the yarn color according to the pattern. During knitting, the front and back needle beds knit the double-sided jacquard structure simultaneously. The pattern on the front is knitted normally according to the design. The needle movement is such that when one set of yarns is knitting loops on the front needle bed, the remaining two sets of yarns are knitted on the back needle bed with skipped stitches. Then, a sesame-like distribution of alternating colors will be formed on the reverse side of the fabric. After knitting b rows, the jacquard structure knitting on the front needle bed is paused.

[0021] S2. Begin knitting the raised stripe structure. At this stage, do not knit the front needle bed. Select at least one yarn (any one of yarns A, B, and C) and knit only c rows of single-sided plain weft stitches on the back needle bed, where c is the number of rows of plain weft stitches in the raised stripe structure. Figure 2 As shown, due to the difference in the number of loops in the front and rear needle beds, the fabric on the back side bulges out, forming a channel with a diameter d≤8mm.

[0022] The rib stitch can also adopt the 1+1 variable plain stitch method. Specifically, the 1+1 variable plain stitch is that the knitting needles on the back needle bed are knitted alternately with 1 float and 1 loop, that is, two courses of knitting complete a pattern cycle, and finally all the knitting needles on the back needle bed participate in the knitting actions of 1 loop formation and 1 float.

[0023] The rib stitch can also adopt the 2+1 variable plain stitch method. Specifically, the 2+1 variable plain stitch is that the knitting needles on the back needle bed are knitted alternately with 2 floats and 1 loop between three courses to complete a pattern cycle, and finally all the knitting needles on the back needle bed participate in the knitting actions of 2 floats and 1 loop formation. Since there is one or two more floats behind the loops of the rib stitch knitted by the variable plain stitch method than that knitted by the plain stitch method, the thickness of the fabric of the rib stitch is increased, which is beneficial to improving the wear resistance of the channel and better protecting the inner pipe; at the same time, since the float is less likely to deform than the loop and has a more stable structure, the inner pipe can be fixed better.

[0024] S3. Repeat the above steps S1 and S2 until a double-sided jacquard stitch with y course numbers is completed, where y is the length of the double-sided jacquard stitch, that is, the course number of the loops. There are ((y / b)-1) rib stitches in this double-sided jacquard stitch.

[0025] In the rib stitch, when a = x, a continuously-through rib stitch is directly knitted, which is a continuous rib stitch, forming a whole channel, and the inner pipe fitting material can be inserted from the cloth edge; when a < x, it is a partial rib stitch. The yarn guide for knitting the rib stitch needs to be brought into the knitting area first, and only part of the knitting needles participate in the knitting. At this time, the yarn is fed in the form of tucking and floating first, and then knitted to form a partial channel. Due to the easily deformed characteristic of the loop structure itself, in order to better fix the inner material, its diameter is slightly smaller than the outer diameter of the inner material, and the inner material can be inserted from the inner side of the fabric edge. This rib stitch can prevent the inner pipe from being exposed from the side and completely cover the pipe fitting, achieving a better protection effect; by repeating the above knitting actions, a fabric with a complete jacquard pattern on the front and a channel on the back can be finally obtained, which has aesthetics and can also cover, fix and protect the inner pipe.

[0026] Example 3 As Figure 3As shown in the left figure, a serpentine channel structure is formed on the back of the fabric to provide more complete coverage of the inserted material and offer more comprehensive protection. In this raised strip structure, the longitudinal channel section can be achieved by adopting a composite structure of floating jacquard and single-sided plain weft knitting, which can be called floating air layer jacquard. The front pattern section uses the front needle bed to weave a floating jacquard structure, while the back needle bed weaves a single-sided plain weft knitting structure. Since there is no connection between the jacquard and the single-sided plain weft knitting structures, the air layer formed can serve as a channel. The steps of weaving the jacquard structure are similar to those in Example 2. The yarn type and jacquard pattern are selected according to the requirements. Since sesame dot jacquard is easier to weave, the pattern of other parts can still be a sesame dot jacquard structure. Then, the parameters of the raised strip structure and the type of plain weft knitting are set according to the characteristics of the material to be inserted. When weaving the raised strip structure, after weaving the transverse channel, a floating jacquard air layer composite structure is adopted for the channel section at the longitudinal corner. Since the floating jacquard structure is woven first on the front, the integrity and continuity of the front jacquard are ensured, and the air layer structure on the back forms a channel.

[0027] In addition, such as Figure 3 As shown in the right figure, a diagonal channel structure is formed on the back of the fabric. This diagonal channel includes multiple parallel channels. The fabric is a composite structure of double-sided sesame jacquard and partial raised stripe structure. The double-sided jacquard structure is similar to the weaving method in Example 1. For the raised stripe structure, the channels are simply woven in a trapezoidal progression. That is, each weave only performs partial raised stripe weaving on a very small number of needles (a≤3) to ensure the visual continuity of the diagonal channels. Then, in the next row, raised stripe weaving is performed on the same number of needles adjacent to the previous row. This visually creates a diagonal effect with the raised stripe of the previous row. This progression continues to the next row and repeats the weaving until a diagonal channel is obtained.

[0028] In summary, the horizontally woven double-sided three-dimensional multi-channel fabric provided by this invention is mainly formed by a composite structure of sesame dot double-sided jacquard weave and raised stripe weave, achieving the effect of a pattern on the front and channels on the back. The pattern on the front is completed by the front and back needle beds, while the channels on it utilize the difference in the number of loops in the front and back needle beds, causing the fabric to bulge and form tubes. At the same time, by changing the number of longitudinal rows, transverse rows, and weave of the raised stripe weave, channels with different three-dimensional structures can be formed to accommodate tubular materials with different diameters and hardness. In addition, the floating jacquard air layer composite jacquard structure can form longitudinal channels, which, combined with transverse channels, can form serpentine channels with full coverage and protection. Simply inserting the material into the tubes can achieve the function of concealment and protection. At the same time, due to the good extensibility of the loop structure, it can fit and fix the tube wall well, making the overall fabric structure more stable. Furthermore, the channels on the back do not affect the pattern on the front. Therefore, this fabric is a covering fabric that combines aesthetics and concealment and protection.
