Description

A single-jersey circular knitting machine and its loop-knitting process and its weft structure Technical Field

[0001] This invention relates to the field of knitting technology, and in particular to a single-sided circular knitting machine, a loop-knitting process, and its liner structure. Background Technology

[0002] Modern single-jersey circular knitting machines feature a two-way fully loop-forming system, employing a single-needle, double-row loop-knitting technique to create loop-knit structures. Loop-knit structures are knitted fabric loops that fall between loop-forming and tuck-knitting patterns. When disassembled, the single-needle, double-row loop-knitting fabric exhibits a pattern of alternating large and small loops, with horizontal and vertical rows interwoven, forming alternating units of double loops. In contrast, traditional single-jersey circular knitting machines typically combine loop-forming, tuck-knitting, and no-knitting (also known as float knitting) techniques to create various single-jersey composite structures. The common feature of weft-knitted fabrics made by single-sided circular knitting machines is that each row of unit loops and loop-knitted, non-knitted, or tucked composite structures are interlocked or interwoven with the previous row. Loop-knitting can be combined with the three conventional single-sided weaving methods, but it can only be double-row loop-knitted, that is, two yarns are divided into two paths and fused together to produce some high-weight fabrics. However, it is difficult to meet the requirements for heavy-weight winter coats or pile fabrics. Currently, most pile fabrics on the market are padded structures. Since the padded yarn is not closed, the suspended arc is easy to slip and pull, which will damage the fabric. Therefore, the existing weft-knitted fabrics made by loop-knitting machines or weft-knitted structures with padded yarns have the following shortcomings (especially common problems of wool fabrics): (1) Lack of dimensional stability: resulting in high shrinkage and easy deformation. (2) Weaving heavy fabrics: requires coarser yarns and is not suitable for pile-knitting processes, and the texture is not uniform and clear. (3) Poor stiffness: The fabric is soft and elastic, lacks a certain degree of stiffness and shape retention, and is not suitable for use as outerwear trousers. (4) Low pilling grade: The stitches are relatively loose and the tightness is not good, making it unsuitable for use as outerwear trousers. Summary of the Invention

[0003] Therefore, to address the aforementioned problems, this invention proposes a single-sided circular knitting machine and a loop-knitting process with its interlocking loop structure. This can change the characteristics of existing loop-knitted fabrics, thereby improving the fabric's dimensional stability, significantly reducing shrinkage, minimizing unraveling and curling, reducing pilling, and enhancing fabric properties. This results in a fabric with a fine, uniform, and clear texture, comparable to woven fabrics in terms of trouser material properties. Furthermore, the interlocking loop structure makes it a preferred weaving solution for heavy-duty warm outerwear fabrics, and the reverse side can be used as the front side of clothing, creating a patterned effect.

[0004] To solve this technical problem, the present invention adopts the following solution: a loop-knitting process for a single-jersey circular knitting machine, comprising a single-jersey circular knitting machine, wherein multiple knitting unit mechanisms are arranged on the cylinder of the single-jersey circular knitting machine body, each knitting unit mechanism including at least three knitting needles with different needle heels, at least three sinkers with different sinker heels, and knitting needle cams and sinker cams respectively paired with the knitting needles and sinkers, the knitting method of the single-jersey circular knitting machine includes loop-knitting using knitting unit mechanisms, the loop-knitting includes one or more loop-knitting units, each loop-knitting unit including a first horizontal knitting, a second horizontal knitting, and a third horizontal knitting performing sequential longitudinal loop-knitting, three... The horizontal knitting forms a complete loop system. Each horizontal knitting includes three yarn feeds. In the first horizontal knitting, the first needle knits into a loop through the knitting unit mechanism in the longitudinal arrangement of reserved loop knitting, reserved tuck knitting, and folded loop knitting. In the second horizontal knitting, the second needle knits into a loop through the knitting unit mechanism in the longitudinal arrangement of reserved tuck knitting, folded loop knitting, and reserved loop knitting. In the third horizontal knitting, the third needle knits into a loop through the knitting unit mechanism in the longitudinal arrangement of folded loop knitting, reserved loop knitting, and reserved tuck knitting. The three horizontal knitting cycles periodically. Each horizontal knitting completes a triple-overlapping loop and interweaves it with the triple-overlapping closed loop already completed in the previous complete loop system. The completed loop shape is stepped.

[0005] Furthermore, after the first, second, and third horizontal rows of knitting are woven into loops, the three yarn feeds are completed.

[0006] The first needle picks up three yarns in sequence from the three-way yarn feed and feeds them into the needle hook. The old loop formed by the first needle in the previous fully loop-forming system, together with the two overlapping sinker arcs and the single needle arc, is combined and interlocked to form a loop in the third way.

[0007] The second needle sequentially picks up three yarns from the three-way yarn feed and feeds them into the needle hook. The old loop formed by the second needle in the previous fully loop-forming system, together with two overlapping sinker arcs and a single needle arc, is combined and interlocked to form a loop, which is then completed in the second way.

[0008] The third needle sequentially picks up three yarns from the three-way yarn feed and feeds them into the needle hook. The old loop formed by the third needle in the previous fully looped system, together with the two overlapping sinker arcs and the single needle arc, is combined and interlocked to form a loop, which is completed in the first way.

[0009] The process of weaving the first, second, and third rows in a cycle, with each row interlacing with the other, weaves a complete loop system.

[0010] Furthermore, in the first horizontal knitting, the first yarn feed performs reserved loop knitting, the first needle rises along the triangular track so that the loop of the needle hook is held by the lower jaw of the first sinker and slides to below the needle tongue, the first needle descends so that the needle tongue is pushed by the old loop and closes to hook the first yarn to the middle position of the nose of the first sinker; in the second yarn feed, the first needle rises along the triangular track so that the loop of the needle hook is held by the nose of the first sinker and slides to above the needle tongue, the first needle descends so that the needle tongue is pushed by the old loop and closes to hook the second yarn to the middle position of the nose of the first sinker; in the third yarn feed, the first needle rises along the triangular track so that the loop of the needle hook is held by the lower jaw of the first sinker and slides to above the needle tongue, the first needle descends so that the needle tongue is pushed by the old loop and closes to hook the third yarn to the first sinker, the first needle descends to below the lower jaw of the first sinker to complete the loop forming action;

[0011] In the second horizontal row knitting, the first yarn feed performs pre-loop knitting, the second needle rises along the triangular track so that the loop of the needle hook is held by the nose of the second sinker and slides to the top of the needle tongue, the second needle descends so that the needle tongue is pushed by the old loop and closes to hook the second yarn to the middle position of the nose of the second sinker; the second yarn feed completes the looping, the second needle rises along the triangular track so that the loop of the needle hook is held by the lower jaw of the second sinker and slides to the top of the needle tongue, the second needle descends so that the needle tongue is pushed by the old loop and closes to hook the third yarn to the second sinker, the second needle descends to the lower jaw of the second sinker to complete the loop forming action; the third yarn feed performs pre-loop knitting, the second needle rises along the triangular track so that the loop of the needle hook is held by the lower jaw of the second sinker and slides to the bottom of the needle tongue, the second needle descends so that the needle tongue is pushed by the old loop and closes to hook the first yarn to the middle position of the nose of the second sinker;

[0012] In the third horizontal row knitting, the first yarn feed completes the loop formation, the third needle rises along the triangular track so that the loop of the needle hook is held by the lower jaw of the third sinker and slides to the top of the needle tongue, the third needle descends so that the needle tongue is pushed by the old loop and closes to hook the third yarn to the third sinker, the third needle descends to the bottom of the lower jaw of the third sinker to complete the loop formation action; the second yarn feed performs reserved loop formation knitting, the third needle rises along the triangular track so that the loop of the needle hook is held by the lower jaw of the third sinker and slides to the bottom of the needle tongue, the third needle descends so that the needle tongue is pushed by the old loop and closes to hook the first yarn to the middle position of the nose of the third sinker; the third yarn feed performs reserved tuck knitting, the third needle rises along the triangular track so that the loop of the needle hook is held by the nose of the third sinker and slides to the top of the needle tongue, the third needle descends so that the needle tongue is pushed by the old loop and closes to hook the second yarn to the middle position of the nose of the third sinker.

[0013] A single-sided composite structure process is an extension of the loop-knitting process of the above-mentioned single-sided circular knitting machine. The weaving method of the single-sided circular knitting machine also includes one or more of loop knitting, tuck knitting, and float knitting. The single-sided composite structure process is a combination of loop-knitting and one or more of loop knitting, tuck knitting, and float knitting to form a variety of single-sided composite structure processes.

[0014] A bobbin weaving structure based on the above-mentioned loop-to-loop knitting circular knitting machine extends the bobbin weaving process. When reserving loops or tuck-knitting positions for single needles in horizontal knitting, the bobbin weaving process is used to feed in additional bobbin yarn. Various fabrics can be produced by sorting the bobbin ratio. The bobbin weaving process is a knitting process derived from the combination of two different reserved loop-to-loop triangles or reserved tuck-knitting triangles with yarn feeding positions. Alternatively, the bobbin weaving process is a knitting process derived from adding a separate triangle in horizontal knitting of loop-to-loop knitting to feed additional bobbin yarn into the bobbin position.

[0015] Furthermore, the process of additionally feeding the bobbin yarn in the bobbin process includes two methods of feeding the bobbin yarn and two different positions for each of the two methods:

[0016] The first method of feeding the liner yarn is to feed it into the needle of the reserved loop. The first yarn is woven in the same way as the loop-knitting. The second yarn is arranged with two different needle heights through the cam and the needle. That is, when the previous yarn feeding system has already woven the reserved loop yarn in the needle hook, the needle tongue selects the needle below the reserved loop yarn to feed the liner yarn of the liner structure into the needle hook together with the previous yarn, so that there are three yarns in the needle hook; or the first method of feeding the liner yarn is to feed it into the needle at another position of the needle of the reserved loop. The second yarn is woven in the same way as the loop-knitting. The first yarn is arranged with two different needle heights through the cam and the needle. When the previous yarn feeding system has already woven the reserved loop yarn in the needle hook, the needle tongue selects the needle above the yarn to feed the second yarn into the liner yarn of the liner structure, so that there are two yarns in the needle hook.

[0017] The second method of feeding the looper yarn involves feeding the yarn into the pre-reserved looping needles at the same method and position. The first yarn is woven in the same way as the looped yarn, while the second yarn is fed into the looper yarn of the looper structure by means of a cam and a needle with two different needle heights. When the pre-reserved looper yarn is woven into the needle hook, the needle tongue selects the needle below the pre-reserved looper yarn and feeds it into the needle hook together, so that there are two yarns in the needle hook. Alternatively, the second method of feeding the looper yarn involves feeding it into the needle at another position of the pre-reserved looper needles. The first yarn is fed into the looper yarn of the looper structure by means of a cam and a needle with two different needle heights. The previous yarn feeding system already has a second yarn fed into the looper structure by means of a cam above the yarn when the pre-reserved looper yarn is woven into the needle hook, so that there is one yarn in the needle hook.

[0018] Furthermore, the bobbin ratio refers to the ratio of the number of loops crossed by the closed loop arc formed by the second bobbin yarn in the weave to the number of loops crossed by the float yarn.

[0019] By adopting the aforementioned technical solution, the beneficial effects of this invention are as follows: By setting a knitting unit mechanism on the upper plate of a single-jersey circular knitting machine, the knitting unit mechanism includes at least three knitting needles with different needle heels, at least three sinkers with different sinker heels, and knitting needle triangles and sinker triangles that are paired with the knitting needles and sinkers respectively, thereby designing a new weaving process on the single-jersey circular knitting machine: loop-to-loop interweaving, namely, a single-needle three-row loop-to-loop interweaving process (a process of interconnection and interweaving by three common loops). The structure woven by loop-to-loop interweaving increases the number of morphological loops between reserved loops and reserved tuck loops in the plain weave loops, and they are arranged regularly to form a twist effect. After the fabric woven by the loop-to-loop interweaving process of this invention is disassembled, the morphological shape of the same horizontal loop is large, In medium and small styles, the horizontal and vertical rows are alternately "woven" in the order of one, two, three, or the loops are arranged in reverse order by the needles and sinkers to form small, medium, and large styles. The horizontal and vertical rows are alternately interlocked in the order of three, two, one in an infinite loop. Measured from the vertical row of a single needle on the fabric, three closed loops are simultaneously interlocked with three old loops from the previous looping system. The adjacent loops are two on the left and one on the right. When the second horizontal row is disassembled, two remain. The adjacent loops are one on the left and three on the right. When the third horizontal row is disassembled, one remains. The adjacent loops are three on the left and two on the right. The needle arc on the front of the fabric is three overlapping closed loops interlocked with three overlapping closed loops. On the reverse side, one sinker arc crosses a horizontal row when the complete loop and the pre-loop intersect. According to the recursive relationship, the loops are continuously cyclical, and the entire interlocking loop weaving process is deduced.

[0020] The weft-knitted fabric produced by the loop-knitting process of this invention has the following comprehensive advantages: it can change the characteristics of existing loop-knitted weft fabrics, thereby improving the dimensional stability of the fabric and significantly reducing shrinkage. Pure wool fabrics have a high shrinkage rate, which has been difficult to overcome effectively. The application of the loop-knitting process significantly improves fabric shrinkage, virtually eliminates the rough hand feel, and greatly enhances anti-pilling performance. Wool yarns have historically had poor evenness; the merging of the three yarns in the loop-knitting process significantly improves the uniformity of the fabric's appearance. Outerwear trousers have high requirements for crispness, shape retention, and wrinkle resistance, which have historically been difficult to match compared to woven products. The high-grammage, tightly woven loop-knitting process has made significant progress in fabric properties, enabling its application to outerwear trousers and providing better skin-friendly performance.

[0021] Furthermore, based on the concept of loop interweaving, a new loop-supporting technique is created by setting up pre-reserved loop-forming or pre-reserved tuck-forming triangles and using double-yarn needle feeding. The completed loop-supporting structure differs from padding structure in that some loops are closed. Like padding structure, the completed loop-supporting structure features floating threads on the reverse side of the fabric, creating a patterned structure. This differs from traditional padding and weft-supporting structures. The term "loop-supporting" refers to adding an inner layer, while "loop" in the industry generally refers to a coil. The name aligns with the coil shape of this technique, and for ease of description and communication, it is called "loop-supporting structure." The loop-supporting structure based on the loop interweaving technique derives two different knitting processes by combining two different pre-reserved loop-forming or pre-reserved tuck-forming triangles with the needle position.

[0022] The weft-knitted fabric with a loop weave structure of the present invention has the following comprehensive advantages: Based on the loop-to-loop weaving process, the loop weave structure surpasses the padding structure in terms of fabric performance, exhibiting low lateral elongation and good shape retention. Furthermore, the loop yarns, bound by the interlocking loops, are less prone to slippage and damage to the fabric's appearance due to external forces. Unique pattern effects can be created by using different loop ratios or fancy yarn combinations, and one side of the loop can be used as the front of the garment. For fleece fabrics, the loop yarns, under the action of a raising machine, form short pile, increasing fabric thickness and improving the fabric's warmth and skin-friendly effect. Because the loop yarns are combed and organized by the raising machine, the front loops are straightened, resulting in a denser fabric with improved anti-pilling properties and a fine, uniform texture, making it a preferred solution for heavy-duty outerwear fabrics.

The sinker cams a and c correspond to the loop structure diagram for yarn 2. In the third horizontal row, the needle cams provide complete loop preparation, loop preparation, and loop preparation. The sinker cams b and c correspond to the loop structure diagram for yarn 3. Loop preparation consists of the longest loop A corresponding to the combination of two adjacent sinker arcs and one needle, and yarn 1. Loop preparation consists of a medium-length loop B (shorter than the longest loop A) and yarn 2, combined with a single sinker arc and one needle. Complete loop preparation consists of a small loop C (usually shorter than the medium-length loop B) and yarn 3, depending on the yarn bending depth. Coil structure diagrams A, B, and C represent the coil shapes of A (reserved for coiling), B (reserved for coiling), and C (fully coiled), corresponding to the coil shapes of A (large), B (medium), and C (small). The coil shapes in the same horizontal row are large, medium, and small. If the horizontal and vertical rows are alternately "woven" in the order of one, two, three, or if the coil shapes are arranged in reverse using needles and sinkers, they will be small, medium, and large. The horizontal and vertical rows will then be interlocked in an infinite loop in the order of three, two, one. Calculated from the warp of a single needle on the fabric, three closed loops are simultaneously nested within each other. Adjacent loops consist of two on the left and one on the right. After disassembling the second row, two loops remain, with one on the left and three on the right of adjacent loops. When disassembling the third row, a single loop remains, with three on the left and two on the right of adjacent loops. The needle arc on the front of the fabric consists of three overlapping closed loops nested within each other. On the reverse side, one sinker arc crosses a row at the junction of a fully formed loop and a pre-formed loop, corresponding to the needle sequence of N1 (first needle 13), N2 (second needle 14), and N3 (third needle 15), and this sequence continues in a continuous cycle. In a complete knitting system, the needles in the three-way feed warp are arranged in segments H, J, and K, the sinkers in segments a, b, and c, and the needle cams and sinker cams are arranged accordingly.

[0044] Based on the loop-knitting process of the single-sided circular knitting machine, the loop-feeding process is used to feed additional loop yarn when reserving loops or tuck knitting positions for single needles in horizontal knitting. Various fabrics can be produced by sorting the loop ratio. The loop-feeding process is a knitting process derived from the combination of two different reserved loop triangles or reserved tuck triangles and the yarn feeding position. The loop ratio refers to the ratio of the number of loop warp rows crossed by the closed loop arc formed by the second yarn loop yarn in the structure to the number of loop warp rows crossed by the float yarn.

[0045] Referring to Figures 7, 8, and 9, the figures illustrate a double-yarn feeding structure based on the concept of loop weaving. This structure uses a pre-reserved tuck loop knitting method with double yarn selection needles. The feeding method for the tuck loop yarn is the same as that of the pre-reserved tuck loop knitting needles. The second yarn is woven in the same way as in loop weaving, while the first yarn is arranged with two different needle heights using cams and needles. The previous yarn feeding system already has a pre-reserved tuck loop yarn woven inside the needle hook. When the needle tongue selects the second yarn above the yarn, the tuck loop yarn of the structure is fed into the needle hook, resulting in two yarns inside the needle hook. Figure 7 shows the pre-tuck loop knitting diagram of the tuck loop structure. The three-section needles and sinkers knit nine rows to form a complete process structure. Figure 8 shows the tuck loop structure... The pre-loop triangular arrangement sequence diagrams 1F and 4F, 2F and 8F, and 6F and 9F are the same as the weaving process of the above-mentioned loop interweaving. The first loop yarn Y3, the second loop yarn Y5, and the third loop yarn Y7 are respectively inserted once in the three rows of a fully looped system according to the loop interweaving process of 3F, 5F, and 7F. Figure 9 is a reverse view of the pre-loop loop structure of the loop weaving. The first yarn 1, the second yarn 2, the third yarn 3, the fourth yarn 4, the fifth yarn 5, the sixth yarn 6, the seventh yarn 7, the eighth yarn 8, and the ninth yarn 9 are the corresponding yarn loop structures woven in the three rows of each of the three sets of fully looped systems. Among them, the corresponding feed In the specific knitting process of 3F, the first loop yarn Y3 is hooked separately on the reserved tuck third needle 15. The first needle 13 and the second needle 14 do not participate in the knitting. The old loops of the previous row's complete loop system on the third needle 15, along with the two overlapping sinker arcs and the single needle arc, plus the first loop yarn Y3, are combined and interlocked to form loops and knitted in 4F. In 5F, the second loop yarn Y5 is hooked separately on the reserved tuck first needle 13. The second needle 14 and the third needle 15 do not participate in the knitting. The old loops of the previous row's complete loop system on the first needle 13, along with the two overlapping sinker arcs and the single needle arc, plus the second loop yarn Y5, are combined and interlocked to form loops and knitted in 6F. F is completed; the third loop yarn Y7 of 7F is hooked separately on the reserved loop second needle 14. The first needle 13 and the third needle 15 do not participate in the knitting. The old loop of the complete loop system of the second needle 14 of the previous row, together with the two overlapping sinker arcs and the single needle arc, plus the third loop yarn Y7 loop yarn, are combined and interlocked to form loops and are completed in 8F; the loop ratio is 1:2 and the floats on the back of the fabric are twill. The loop structure is different from the padding structure in that some loops are closed. The completed loop structure is the same as the padding structure in that the floats on the loops are a patterned structure on the reverse side of the fabric. Nine rows of three different loops are knitted in a loop system.

[0046] Referring to Figures 10, 11, and 12, Figure 12 illustrates a second extension of the loop-knitting concept, using a pre-reserved loop knitting method with double-yarn needle feeding. The feeding method for the loop yarn is to feed it into the pre-reserved loop knitting needle. The first yarn is arranged with two different needle heights, using triangles and knitting needles. When the previous yarn feeding system has already knitted the pre-reserved loop yarn in the needle hook, the needle tongue selects the second yarn above the yarn and feeds it into the loop yarn of the loop structure, so that there is only one yarn in the needle hook. Figure 10 is a loop structure pre-reserved loop knitting diagram. The three-section knitting needles and sinkers knit nine rows to form a complete process structure. Figure 11 is a loop structure pre-reserved loop triangle arrangement diagram. 1F and 4F, 2F and 8F, 6F and 9F are arranged in the same way as the loop-knitting process described above. The fourth loop yarn Z3, the fifth loop yarn Z5, and the sixth loop yarn Z7 are respectively inserted once in each of the three rows of a complete loop system using a loop-to-loop weaving process. Figure 12 is a reverse view of the pre-loop structure of the loop weave. The first yarn 1, the second yarn 2, the third yarn 3, the fourth yarn 4, the fifth yarn 5, the sixth yarn 6, the seventh yarn 7, the eighth yarn 8, and the ninth yarn 9 are the corresponding yarn loops woven into three rows of each of the three complete loop systems. In the specific knitting process corresponding to the yarn feeding, the fourth loop yarn Z3 of 3F is hooked separately on the reserved loop-forming second needle 14. The first needle 13 and the third needle 15 do not participate in the knitting. The old loop of the previous row's second needle 14, which is completely looped, along with the two overlapping sinker arcs and the single needle arc, plus the fourth loop yarn Z3, are combined and interlocked to form loops and knitted in 5F. The fifth loop yarn Z5 of 5F is hooked separately on the reserved loop-forming third needle 15. The first needle 13 and the second needle 14 do not participate in the knitting. The old loops of the complete loop system of the third needle 15 in the previous row, along with two overlapping sinker arcs and a single needle arc, plus the fifth loop yarn Z5, are combined and interlocked to form loops on the 7th floor. The sixth loop yarn Z7 on the 7th floor is separately hooked on the reserved first loop needle 13. The second needle 14 and the third needle 15 do not participate in the knitting. The old loops of the complete loop system of the first needle 13 in the previous row, along with two overlapping sinker arcs and a single needle arc, plus the sixth loop yarn Z7, are combined and interlocked to form loops on the 9th floor. Completed; the liner ratio is 1:2. The floats on the back of the fabric are twill. The liner structure differs from the padding structure in that some loops are closed. The completed liner structure is similar to the padding structure in that the floats on the loops remain on the reverse side of the fabric. Nine horizontal rows of three different liner loops are woven in a complete loop system. Comparing the reserved loops and reserved loops in the liner structure, the reserved loop yarns will be exposed on the front side of the fabric, while the reserved loop yarns are covered in the middle of the loops and are not easily exposed.

[0047] In the above embodiments, the feeding of the bobbin yarn in the bobbin weaving process can be divided into two independent triangles to feed the extra bobbin yarn separately, achieving the same bobbin weaving process of reserved loop formation and reserved loop gathering. The additional feeding of looper yarn in the looper process can also include two other methods and positions for feeding looper yarn: Another method is to feed the looper yarn into the needles of the reserved loop. The first yarn is woven in the same way as the loop-knitting, and the second yarn is arranged with two different needle heights through the cam and the knitting needle. That is, when the previous yarn feeding system has already woven the reserved loop yarn in the needle hook, the needle tongue selects the needle below the reserved loop yarn and feeds the looper yarn of the looper structure into the needle hook together with the previous yarn, so that there are three yarns in the needle hook; Another method is to feed the looper yarn into the needles of the reserved loop. The first yarn is woven in the same way as the loop-knitting, and the second yarn is arranged with two different needle heights through the cam and the knitting needle. When the reserved loop yarn is woven in the needle hook, the needle tongue selects the needle below the reserved loop yarn and feeds the looper yarn of the looper structure into the needle hook together, so that there are two yarns in the needle hook.

[0048] The loop-knitting process described in the above embodiments can also be combined with the weaving methods of conventional single-jersey circular knitting machines to achieve a single-jersey composite structure process extended from the loop-knitting process of the above-mentioned single-jersey circular knitting machine. This involves combining existing single-jersey circular knitting machine weaving methods: loop knitting, tuck knitting, and float knitting to form a single-jersey composite structure process. Specifically, the single-jersey composite structure process is a combination of loop-knitting with one or more of the following weaving methods: loop knitting, tuck knitting, and float knitting, to complete various single-jersey composite structure processes for fabric weaving. In the above embodiments, the knitting needles in each knitting unit mechanism can be either single-needle-heel needles or double-needle-heel needles with a second heel added to the end of the heel track. The sinker can be either single-piece-heel sinker or double-piece-heel sinker with a second heel added to the end of the piece-heel track. Each knitting unit mechanism can also consist of the following structure: at least three knitting needles with heels in different positions, at least three sinkers with heels in different positions, and needle cams and sinker cams paired with the knitting needles and sinkers respectively. Alternatively, each knitting unit may also consist of the following structural configuration: including at least one stitch unit, at least one set of sinker units, and needle triangles and sinker triangles paired with each stitch unit and each set of sinker units respectively. More than one set of interlocking knitting units can be used, such as two sets of interlocking knitting units, each set including a first horizontal row of knitting, a second horizontal row of knitting, and a third horizontal row of knitting. Interlocking knitting can also be done without using interlocking knitting units, directly using at least three horizontal rows of knitting to complete a complete loop system: each horizontal row of knitting must simultaneously include single-needle loop preparation, single-needle loop preparation, and single-needle interlocking knitting. Each horizontal row of knitting completes a unit of triple-overlap loop and interlocks with the previously completed triple-overlap closed loop in a longitudinal loop. Based on the recursive relationship, the entire interlocking knitting process needs to be deduced by arranging the three horizontal rows in three staggered positions. The completed loop shape is stepped, and the three horizontal rows cycle periodically.
