Description

Technical Field

[0001] This invention relates to the field of knitting, and more particularly to a single-sided weft-inserted structure and its knitting method. Background Technology

[0002] Single-sided construction is the foundation for manufacturing lightweight, breathable, fully-formed footwear materials. While weft-knitted single-sided structures offer good shape retention, they suffer from insufficient shape retention and lower transverse strength. To enhance structural stability, a certain amount of yarn is often inserted into the fabric, such as single-sided weft-insertion and single-sided warp-insertion. Single-sided warp-insertion is more complex and less efficient than single-sided weft-insertion. Single-sided weft-insertion often employs a transverse non-woven technique, using knitting or reverse stitching to hold the weft yarn in place, creating a structure where the weft yarn is only inserted without forming loops. However, compared to warp-insertion, single-sided structures have lower yarn holding effectiveness, resulting in the weft yarn easily slipping or becoming exposed, which is detrimental to the final product's usability.

[0003] Therefore, how to improve the low clamping effectiveness of weft yarns in single-sided weft-inserted structures and reduce slippage and hooking of weft yarns is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a single-sided weft-inserted structure to improve the problem of low clamping effectiveness of weft yarn in the single-sided weft-inserted structure and reduce slippage and hooking of the weft yarn.

[0005] Another object of the present invention is to provide a weaving method for a single-sided weft-inserted structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A single-sided weft-inserted structure is woven from a first yarn and a second yarn. The first yarn is woven into loops, and the second yarn is a weft-inserting yarn. Two second yarns are inserted in the same horizontal row, and the two second yarns cross each other to achieve interlocking.

[0008] Optionally, in the above-mentioned single-sided weft-inserted structure, the two second yarns inserted in the same row have multiple intersections.

[0009] Optionally, in the above-described single-sided weft-insertion structure, the loops woven by the first yarn include loops and coiled loops, and the two second yarns on the same horizontal row cross each other at the elongated loop position of the coiled loop.

[0010] Optionally, in the above-described single-sided weft-insertion structure, the two second yarns on the same horizontal row cross each other at the front and back of the elongated loop of the coiled loop, so that the position of any second yarn on the same horizontal row at the elongated loop of the coiled loop switches between the front and back of the loop.

[0011] Optionally, in the above-mentioned single-sided weft-lined structure, the elongated coils of the coiled coils on the same horizontal row are multiple coils that are spaced apart.

[0012] Optionally, in the above-described single-sided weft-insertion structure, multiple coiled coils are included between the elongated coils of two adjacent coiled coils.

[0013] Optionally, in the above-described single-sided weft-inserted structure, the first yarn and the second yarn may be made of the same or different materials.

[0014] A knitting method for a single-sided weft-inserted structure, using a computerized flat knitting machine with a pair of needle beds facing each other in the front-back direction, is characterized by comprising the following steps:

[0015] The first yarn forms a loop. The first yarn completes the looping or gathering on the front needle bed according to the set parameters, and enters the corresponding needle on the rear needle bed at intervals of the set number of stitches.

[0016] The second yarn is inserted, and the head of the computer flat knitting machine moves laterally into the knitting area. The second yarn is inserted in a non-woven form using a weft yarn guide.

[0017] As the coil flips, the head of the computerized flat knitting machine moves laterally, causing the coil on the rear needle bed to flip back to its original position on the front needle bed.

[0018] Optionally, in the above-described single-sided weft-inserted structure knitting method, before the step of inserting the second yarn, the method further includes the step of yarn guide: yarn guide, wherein the same weft yarn guide has two yarn guides, each of which carries two weft yarns and guides them into the middle of the teeth of the front needle bed and the rear needle bed.

[0019] Optionally, in the above-described method for weaving a single-sided weft-inserted structure, the step of inserting the second yarn further includes the step of: the second yarn crossing, whereby when the two yarn tips of the same weft yarn guide move to the position of the elongated loop of the tufting loop, the two yarn tips of the same weft yarn guide deflect to form two second yarns crossing.

[0020] The single-sided weft-inserted structure provided by this invention is woven from a first yarn and a second yarn. The first yarn is used to weave loops, and the second yarn is the weft yarn. Two second yarns are inserted in the same horizontal row, and the two second yarns interlock to achieve interlocking. The weft-inserted structure provided by this invention achieves effective weft insertion in single-sided weft fabrics through the interlocking of two second yarns in the same horizontal row, reducing slippage and hooking of the weft yarn, and effectively improving the problem of low weft yarn clamping effectiveness in single-sided weft-inserted structures.

[0026] The core of this invention is to provide a single-sided weft-inserted structure to improve the problem of low clamping effectiveness of weft yarn in single-sided weft-inserted structures and reduce slippage and hooking phenomena of weft yarn;

[0027] Another object of the present invention is to provide a weaving method for a single-sided weft-inserted structure.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figure 1 As shown, an embodiment of the present invention discloses a single-sided weft-inserted structure, including a first yarn 110 and a second yarn 120.

[0030] Specifically, the single-sided weft-inserted structure disclosed in this embodiment of the invention is woven from a first yarn 110 and a second yarn 120. The first yarn 110 is woven into loops, and the specific type of loops is not limited; they can all be looped loops, or a combination of looped loops and tucked loops. The second yarn 120 is the weft yarn, and two second yarns 120 are inserted in the same horizontal row. The two second yarns 120 cross each other to achieve interlocking. Those skilled in the art will understand that the specific crossing position of the two second yarns 120 is not limited, as long as the cross interlocking is achieved. The first yarn 110 and the second yarn 120 can be yarns of the same properties, or yarns of different properties, such as different colors, shapes, and elasticities. The specific yarn properties are selected according to the actual situation.

[0031] The single-sided weft-insertion structure disclosed in this invention achieves effective weft insertion of the single-sided structure by interlocking two second yarns 120 in the same horizontal row, reducing the slippage and hooking phenomenon of the second yarns 120, and effectively improving the problem of low clamping effectiveness of weft yarns in the single-sided weft-insertion structure.

[0032] like Figure 1 As shown, in order to further reduce the slippage and hooking phenomenon of the second yarn 120, in a specific embodiment of the present invention, the two second yarns 120 inserted on the same horizontal row have multiple intersections. The setting of multiple intersections can effectively improve the problem of low clamping effectiveness of weft yarn in single-sided weft-inserted structure. The specific intersection position is set according to the actual situation.

[0033] To ensure the strong interlocking of the two second yarns 120 in the same horizontal row, in a specific embodiment of the present invention, at the same loop position woven by the first yarn 110, the two second yarns 120 in the same horizontal row are respectively placed on the front and back of the loop. For example, if one second yarn 120 is placed on the front of the loop, then the other second yarn 120 is placed on the back of the loop. This arrangement can ensure the strong interlocking of the two second yarns 120.

[0034] like Figure 1As shown, to better support the crossing of two second yarns 120 in the same horizontal row and enrich the fabric style, in a specific embodiment of the present invention, the basic loop of the first yarn 110 includes a looping loop and a tucked loop. The first yarn 110 tucks together to form an elongated loop 130 of the tucked loop. The two second yarns 120 in the same horizontal row cross each other at the elongated loop 130 of the tucked loop, specifically at the loop post of the elongated loop 130. Those skilled in the art will understand that the tucked loop can be a single-needle loop or a multi-needle loop, depending on actual needs. The crossing position of the two second yarns 120 in the same horizontal row at the elongated loop 130 of the same tucked loop can be one place or two places, depending on the actual situation. The elongated loop of the tucked loop not only provides support for the crossing of the two second yarns 120, but the formed holes also enrich the fabric style, providing comfort and breathability.

[0035] Based on the above embodiment, two second yarns 120 on the same horizontal row cross before and after the elongated loop 130 of the loop-forming coil, respectively. This allows any second yarn 120 on the same horizontal row to switch between the front and back sides of the loop at the location of the elongated loop 130. That is, at the loop-forming coil position, one second yarn 120 is on the front side of the loop-forming coil, and the other second yarn 120 is on the back side. Taking the second yarn 120 located on the front side of the loop-forming coil as an example, it crosses with another second yarn 120 before the elongated loop 130 of the loop-forming coil, changing to be on the back side of the elongated loop 130. It then crosses with another second yarn 120 after the elongated loop 130 of the loop-forming coil, changing to be on the front side of the loop-forming coil. This arrangement makes the interlocking of the two second yarns 120 more secure, achieving effective weft insertion.

[0036] Based on the above embodiments, multiple coiled loops are spaced apart on the same horizontal row, and multiple looping loops are included between two adjacent coiled loops. Specifically, the multiple coiled loops can be of the same type or a combination of different types. The coiled loops can be evenly distributed or unevenly distributed. The specific number of looping loops is set according to actual needs, and different arrangements can create different fabric styles.

[0037] like Figure 2 As shown, this embodiment of the invention also discloses a knitting method for a single-sided weft-inserted structure, which uses a computerized flat knitting machine having a pair of needle beds facing each other in the front-back direction, and includes the following steps:

[0038] S10, the first yarn is looped;

[0039] The first yarn 110 forms loops or tucks on the front needle bed according to set parameters, and then performs a turning-over operation at set intervals before entering the corresponding needles on the rear needle bed. Those skilled in the art will understand that the specific number of stitches for the turning-over interval of the loops can be set according to actual needs and is not limited here. The specific type of tuck loop is also set according to actual needs. The tuck loops can be distributed at certain intervals to ensure a uniform distribution of the tuck loop positions on the fabric.

[0040] S20, insert the second yarn;

[0041] The head of the computerized flat knitting machine moves laterally into the knitting area, and the second yarn 120 is inserted in a non-woven form using a weft yarn guide.

[0042] S30, coil flipping;

[0043] The machine head of the computerized flat knitting machine moves laterally, causing the coils on the rear needle bed to flip back to their original needle positions on the front needle bed.

[0044] It should be noted that the above steps are the same regardless of whether the knitting machine head moves to the left or right. Repeat the above steps in a loop as needed to knit the fabric and obtain the required single-sided weft-insulated fabric.

[0045] Based on the above embodiments, before the step of inserting the second yarn, a yarn feeder introduction step is also included. In the single-sided weft-inserted structure knitting method disclosed in the embodiments of the present invention, the computer flat knitting machine used has a special double weft yarn guide. The same weft yarn guide has two yarn feeders. Each of the two yarn feeders carries two second yarns 120 and guides them into the middle of the teeth of the front needle bed and the rear needle bed. The second yarn 120 is inserted after the first yarn 110 is looped or gathered.

[0046] The single-sided weft-inserted structure knitting method disclosed in this embodiment of the invention further includes a second yarn crossing step in the step of inserting the second yarn. When the two yarn tips of the same weft yarn guide move to the position of the elongated loop 130 of the coiled loop, the two yarn tips deflect to form two second yarns 120 crossing.

[0047] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
