Description

Technical Field

[0001] The present invention relates to the technical field of single-sided circular weft knitting machines, and specifically relates to an interlaced plating fabric and a component for a single-sided circular weft knitting machine. Background Art

[0002] Single-sided weft knitting plating fabrics are very common in single-sided weft knitted fabrics. Like the vast majority of other weft knitted fabrics, ordinary single-sided weft knitting plating fabrics have very good lateral and longitudinal elasticity. This is their advantage, but in some cases it can also become a disadvantage. For example, because of their too good lateral and longitudinal elasticity, that is, poor dimensional stability and poor fabric stiffness, ordinary single-sided weft knitting plating fabrics are not suitable as materials for outerwear. In fact, poor dimensional stability and stiffness are common disadvantages of all weft knitted fabrics.

[0003] As Figure 1 shown, it is a coil diagram of an ordinary plating stitch. For the knitted fabric of the plating stitch, all or part of its coils, which are formed by a basic yarn and an additional yarn together, are called the plating stitch. Figure 1 Shown in Figure 1 is the reverse side of the fabric. First of all, weft knitted fabrics are formed by stringing one coil after another. Figure 1 It can be seen in

[0004] that each coil of the fabric is composed of two yarns. All or part of the coils of the knitted fabric, which are formed by a basic yarn and an additional yarn together, are called the plating stitch. This is the concept of the plating stitch. In Figure 2 shown, the green yarn is exposed on the front of the fabric, so it is called the face yarn, while the pink yarn is exposed on the reverse side of the fabric. Because this yarn is an extra existence outside the face yarn, it is called the plating yarn. It should be noted that in this fabric, the face yarn is always the face yarn; and the plating yarn is always the plating yarn.

[0005] As Figure 3 shown, it is the situation when an ordinary plating fabric is longitudinally stretched. When longitudinally stretched, a part of the needle loop arc C1 and the sinker loop arc C2 will be converted into the loop stem C3 due to the longitudinal tension, and the loop stem C3 becomes longer, so the fabric elongates longitudinally. Figure 2 And Figure 3 illustrate that ordinary plating fabrics have good lateral and longitudinal stretching elasticity. This bidirectional elasticity is a unique advantage of knitted fabrics. However, in some cases it can also become a disadvantage. For example, because of the too good elasticity, the fabric has poor dimensional stability and poor stiffness, so it is not suitable for use as outerwear fabric.

[0006] In view of this, the inventors of the present application have designed an interlaced plating fabric and a component for a single-sided circular weft knitting machine, in order to overcome the above technical problems. Summary of the Invention

[0024] The positive and progressive effects of the present invention are as follows:

[0025] The interlock fabric with alternate plating of the present invention and the components for a single - jersey circular weft knitting machine at least have the following advantages:

[0026] First, the longitudinal elasticity of the interlock fabric with alternate plating of the present invention is very small and the lateral elasticity is relatively small. Therefore, it has good longitudinal dimensional stability and relatively good lateral dimensional stability. This characteristic of slight longitudinal elasticity and low lateral elasticity just meets the requirements for the materials of outer garments. At the same time, due to the introduction of plating, the weight and stiffness of the fabric are improved, so it is suitable as the material for outer - garment clothing.

[0027] II. The components of the present invention for a single-sided circular weft knitting machine form a loop arc of the face yarn by making the knitting needles move along the non-dropping cam and combining with the sinker track that does not retract, so that the yarn bends over the upper edge of the sinker without dropping stitches, thus preparing for hooking the second yarn to form a plating loop together. Since the old loop is held in the throat of the sinker, if the face yarn also bends over the lower edge of the sinker, the old loop will surely be dropped because the needle tip is lower than the lower edge of the sinker, and thus the loop arc of the face yarn will not be formed, but a direct loop will be formed instead. The present invention ingeniously uses the upper edge of the sinker as the bending and holding surface of the face yarn, and uses the height difference between the upper and lower edges of the sinker to form the required pre-bending length of the face yarn on the knitting needle. Since the height of the knitting needle is higher than the lower edge of the sinker, the old loop will not be dropped, preparing for the subsequent formation of the plating loop.

[0028] III. The components of the present invention for a single-sided circular weft knitting machine use two types of sinkers. By configuring two sinker cam tracks to control the movement trajectories of the two types of sinkers respectively, and adding the interlaced configuration of tuck cams and non-dropping cams, the knitting needles work alternately to pre-bend the face yarn and form the plating loop state, and the yarn alternately appears as the face yarn and the plating yarn. This alternately presented plating loop and the cross-presented extension yarn endow the fabric with new characteristics, namely, very small longitudinal elasticity and certain transverse elasticity, filling the gap of weft knitted fabrics.

[0078] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention is provided in conjunction with the accompanying drawings.

[0079] Now, reference will be made in detail to the preferred embodiments of the present invention, which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals will be used throughout the drawings to refer to the same or like parts. In addition, although the terms used in the present invention are selected from well-known and commonly used terms, some of the terms mentioned in the specification of the present invention may be selected by the applicant according to his or her judgment, and their detailed meanings are described in the relevant parts of the present description. In addition, it is required to understand the present invention not only by the actual terms used, but also by the meaning implied by each term. At the same time, for the convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationship.

[0080] See Figure 4 、 Figure 5 and Figure 18 The present invention provides an interlaced plating fabric, which includes two yarns. The coil composition structure of the interlaced plating fabric is in an interlaced state. The face yarn of each coil comes from the previous knitting course, while the plating yarn comes from the current knitting course; the connecting yarns between the coils are in a crossed state, and the two yarns alternately appear as face yarn and plating yarn in the transverse direction respectively.

[0081] The elasticity of a common single-sided weft-knitted plating fabric is too large, so its dimensional stability and stiffness are poor, resulting in its unsuitability as a material for outerwear. Compared with the common single-sided weft-knitted plating fabric, the interlaced plating fabric of the present invention has very little longitudinal elasticity and relatively small transverse elasticity, so it has good longitudinal dimensional stability and good transverse dimensional stability. This characteristic of small longitudinal elasticity and low transverse elasticity just meets the requirements of materials for outerwear. At the same time, due to the introduction of the plating yarn, the weight and stiffness of the fabric are improved, so it is suitable as a material for outerwear.

[0082] Figure 4 As shown in Figure 4 1, 1', 1", 2, 2' in the figure are coils, and 3, 4 are connecting yarns, that is, sinker loops C2.

[0083] Each coil of the interlaced plating fabric of the present invention is still composed of two yarns, and the biggest difference from the common plating structure lies in:

[0084] 1. The composition structure of the coils is in an interleaved state, as Figure 4 shown. Coils 1, 1', and 1" are in the same state, with green yarn as the face yarn and pink yarn as the plating yarn. That is, the coil structures of all odd-numbered wales are the same, and the coil structures of all even-numbered wales are also the same.

[0085] 2. The face yarn of each plating coil comes from the previous knitting course. For example, for coil 1, its face yarn is blue yarn, and the blue yarn comes from the previous knitting course, where the blue yarn acts as the plating yarn in the previous knitting course. Similarly, for coil 2, its face yarn is red yarn, which also comes from the previous knitting course and acts as the plating yarn in the previous knitting course. Therefore, the function of each yarn varies depending on its position in different wales. The function of the yarn changes between different wales.

[0086] 3. Since the face yarn of each coil comes from the previous knitting course, and the pulling force on the fabric during knitting is continuous. This results in a certain height difference in the longitudinal direction between adjacent wales of the coils. Therefore, the extension lines (sinker loops C2) between the coils are in a crossed state. For example, the extension line 3 of coil 1 and the extension line 4 of coil 2 are in a crossed state. While in the Figure 1 ordinary plating fabric shown, the extension lines (sinker loops C2) between the wales are in a parallel state.

[0087] 4. The two yarns are interleaved horizontally and are respectively shown as the face yarn and the plating yarn.

[0088] Due to the above four characteristics, this structure is called the interleaved plating structure. Figure 4 The red arrow and the blue arrow in

[0089] Figure 5 show the displacement trends of the two yarns when the fabric is longitudinally stretched. It can be seen that the displacement trends of the two yarns are exactly opposite and cancel each other out. Therefore, it is almost impossible to stretch longitudinally. This shows that the interleaved plating fabric has very little longitudinal elasticity, that is, it has good longitudinal dimensional stability.

[0090] See Figures 6a - 17b 、 Figures 19 - 20, the present invention also provides a component for a single-sided circular weft knitting machine, and the component for the single-sided circular weft knitting machine is used to produce the above-mentioned alternating plating fabric. The component for the single-sided circular weft knitting machine includes knitting needles 100, sinkers 200, knitting needle cam tracks 300, and sinker cam tracks 400;

[0091] The knitting needle 100 includes a needle bar 110, a needle hook 120, a needle tongue 130, and a needle butt 140; the needle hook 120 is arranged at the upper end of the needle bar 110; the needle tongue 130 is arranged at the upper part of the needle bar 110 and is rotatably connected to the needle bar 110 for closing or opening the needle hook 120; the needle butt 140 is embedded in the knitting needle cam track 300;

[0092] The sinker 200 includes an upper sinker nose 210, a lower sinker nose 220, and a sinker heel 230; the lower sinker nose 220 serves as the first yarn bending and holding surface; the upper sinker nose 210 serves as the second yarn bending and holding surface; the sinker heel 230 is embedded in the sinker cam track 400.

[0093] Preferably, the knitting needle 100 of the component for the single-sided circular weft knitting machine of the present invention uses a latch needle, Figure 6a and Figure 6b shown are the latch needle and its main components, as well as different knitting states.

[0094] The latch needle is a type of knitting needle 100 and is the most widely used knitting needle 100 on circular weft knitting machines and is one of the main knitting devices. The latch needle mainly consists of a needle hook 120, a needle tongue 130, a needle bar 110, and a needle butt 140. The needle tongue 130 can rotate around the needle tongue pin 131, so that the needle hook 120 is in a closed or open state.

[0095] As Figure 6a and Figure 6b shown, during the knitting process, as the knitting needle 100 rises, the coil C slides downward along the needle bar 110 from top to bottom. During this process, the coil C slides over the needle tongue 130, causing the needle tongue 130 to rotate around the needle tongue pin 131 and open. After opening, the needle hook 120 is in an open state, so that a new yarn can be hooked in the subsequent knitting process for the next step of knitting. The closing of the needle tongue 130 is a reverse process. During the downward movement of the knitting needle 100, the coil C slides upward over the needle tongue 130, causing the needle tongue 130 to rotate around the needle tongue pin 131, so that the needle tongue 130 closes on the needle hook 120, and the coil C then turns over the needle hook 120 and is strung on the new yarn, forming a new coil C of the new yarn. The needle butt 140 is embedded in the knitting needle cam track 300, and the knitting needle 100 is pushed to move up and down through the preset trajectory of the knitting needle cam track 300.

[0096] Figure 7As shown, it is a schematic diagram of the sinker 200 and its main parts. The sinker 200 is also one of the important knitting components. Preferably, the sinker 200 consists of parts such as the sinker throat 240, the lower sinker nose 220, the upper sinker nose 210, and the sinker heel 230. The function of the sinker throat 240 is to control the coil. During the upward movement of the knitting needle 100, the upper edge of the sinker throat 240 catches the old coil to prevent the old coil from climbing with the knitting needle 100, which enables the loop withdrawal to be completed. The lower edge of the sinker throat 240 serves as a yarn bending support surface (i.e., the first yarn bending support surface). When the knitting needle 100 descends to hook the new yarn, the new yarn bends between the lower sinker nose 220 and the needle hook 120, enabling the knitting needle 100 to absorb a certain amount of yarn in preparation for forming a new coil. The upper sinker nose 210 of the sinker 200 usually has no function. It is just a geometric entity formed to shape the sinker throat 240. However, in the components of the present invention for a single-sided circular weft knitting machine, the upper sinker nose 210 serves as another yarn bending support surface (i.e., the second yarn bending support surface). The sinker heel 230 of the sinker 200, like the needle butt 140 of the knitting needle 100, is also the part that drives the sinker 200 to move in and out.

[0097] Figure 10 As shown, it is a schematic diagram of the yarn bending on the lower sinker nose 220 of the sinker 200. The new yarn is held on the lower sinker nose 220. As the knitting needle 100 descends, the yarn bends between the needle hook 120 and the lower sinker nose 220 of the sinker 200, enabling the knitting needle 100 to obtain the new yarn required for loop formation.

[0098] Figure 11 As shown, it is a schematic diagram of the yarn bending on the upper sinker nose 210 of the sinker 200. As mentioned above, usually the upper sinker nose 210 of the sinker 200 has no function. In the present invention, the upper sinker nose 210 of the sinker 200 is used as the second yarn bending support surface, enabling the knitting of the alternating plating stitch. The new yarn is held on the upper sinker nose 210. As the knitting needle 100 descends, the yarn bends between the needle hook 120 and the upper sinker nose 210 of the sinker 200, enabling the knitting needle 100 to obtain the new yarn required for loop formation.

[0099] See Figures 12 - 14 , as a preferred embodiment of the components of the present invention for a single-sided circular weft knitting machine, the knitting needle cam track 300 includes a knitting needle tucking cam 310 and a knitting needle non - dropping cam 320; the knitting needle tucking cam 310 and the knitting needle non - dropping cam 320 are alternately arranged on the knitting needle cam track 300 (hereinafter simply referred to as the tucking cam and the non - dropping cam for the knitting needle tucking cam 310 and the knitting needle non - dropping cam 320).

[0100] See Figures 12 - 14, as a preferred embodiment of the component of the present invention for a single-sided circular weft knitting machine, the highest point of the runway of the knitting needle tuck cam is lower than the highest point of the runway of the knitting needle non-dropping cam, and the runway exit of the knitting needle non-dropping cam is higher than the runway exit of the knitting needle tuck cam.

[0101] It should be noted that the non-dropping cam is a specially designed cam. Its characteristic is that even when the knitting needle 100 descends to the lowest height, the needle hook 120 of the knitting needle 100 is still higher than the lower blade edge 220 of the sinker 200, so the old loop will not be dropped off, as Figure 13 shown.

[0102] The lowest point of the pressing needle of the non-dropping cam is higher than that of the normal knitting cam. Its height is designed such that the old loop still has not passed over the needle tip after passing through the lowest point of the pressing needle, so it is called the non-dropping cam.

[0103] Figure 12 Shown is a working schematic diagram of the tuck cam. For comparison with the tuck cam, the knitting cam is on the left in the figure. For the convenience of description, the knitting cam will be briefly introduced here: As the knitting needle 100 climbs, the old loop a retreats onto the needle bar 110, and at the same time the latch 130 is opened. The knitting needle 100 hooks the new yarn, and yarn bending is carried out on the yarn bending holding surface of the sinker 200. The knitting needle 100 further descends, and the old loop a passes over the needle tip of the knitting needle 100 and nests on the new yarn. Because of the nesting, a closed new loop b will be formed, which is the normal knitting process.

[0104] Figure 12 On the right in [the figure] is the tuck cam. The difference between the tuck cam and the knitting cam is that the climbing height of the knitting needle 100 is lower, so that the old loop a cannot slide off the latch 130 and retreat onto the needle bar 110, but the latch 130 is also already opened. Therefore, when the knitting needle 100 descends, the knitting needle 100 hooks the new yarn c, and the old loop returns into the needle hook 120 again and is together with the new yarn c. The above is the meaning of "tuck" in tucking, which means to gather or assemble.

[0105] At the same time, since the old loop is not nested on the new yarn, the new yarn cannot form a closed loop, but only an isolated loop arc, and this loop arc and the old loop are both in the needle hook 120, and there are two yarns in the needle hook 120. The old loop refers to the old loop already existing on the knitting needle 100, the new yarn refers to the newly fed yarn in the current knitting course, and the new loop is the complete loop structure formed by the new yarn in the current knitting course.

[0106] Figure 13As shown, it is a working schematic diagram of the no-dropping loop cam. For the sake of comparison, the loop-forming cam is still on the left side in the figure, which will not be elaborated here. It can be clearly seen from the shape of the no-dropping loop cam on the right that the difference between it and the loop-forming cam is that during the descending process of the knitting needle 100, the knitting needle 100 will not descend as much as the loop-forming cam, but "stop halfway" (the height of the runway exit of the no-dropping loop cam is higher than that of the loop-forming cam, and the height difference between the two is H). The knitting needle 100 first climbs, and the old loop a slides over the latch 130 and retreats to the needle shank 110. Then the knitting needle 100 descends while hooking the new yarn. The difference is that the stroke of the knitting needle 100 descending is not as much as that of the loop-forming cam. Therefore, the old loop is not enough to pass over the tip of the knitting needle 100, but still stays on the latch 130 when the knitting needle 100 descends, which is the reason why it is called the "no-dropping loop cam".

[0107] Since the old loop does not pass over the tip of the knitting needle 100, it is not nested on the new yarn. Therefore, the new yarn only forms an isolated loop arc in the needle hook 120, and there is only one yarn in the needle hook 120, while the old loop is still on the latch 130 (outside the needle hook 120).

[0108] Through the above introduction of the tuck cam and the no-dropping loop cam, we notice the common points and differences between the tuck cam and the no-dropping loop cam 320 of the knitting needle. The common points of the two are: at the end of knitting, both cams will make the new yarn form an unclosed loop arc instead of a closed coil. The difference points are: after passing through the tuck cam, the old loop stays in the needle hook 120 together with the loop arc of the new yarn, so there are two yarns in the needle hook 120; while after passing through the no-dropping loop cam, the old loop is still on the latch 130 (outside the needle hook 120), and there is only the loop arc of the new yarn in the needle hook 120.

[0109] See Figures 16 - 17b , as a preferred embodiment of the component of the present invention for a single-sided circular weft knitting machine, the sinker cam runway 400 includes a sinker exit cam 410 and a sinker float cam 420; the sinker exit cam 410 and the sinker float cam 420 are alternately arranged on the sinker cam runway 400.

[0110] See Figures 16 - 17b , as a preferred embodiment of the component of the present invention for a single-sided circular weft knitting machine, the sinker exit cam 410 is arranged to protrude outward on the sinker cam runway 400, and the sinker float cam 420 is arranged to be basically straight. (The sinker exit cam 410 and the sinker float cam 420 are hereinafter simply referred to as the exit cam and the float cam)

[0111] As Figure 16As shown in the figure, the withdrawal cam is arranged on the first path of the first sinker cam track 430, and it has a convex structure. When the first sinker 250 runs to this convex structure, the first sinker 250 withdraws outward to cooperate with yarn laying. The float cam is arranged on the second path of the first sinker cam track 430. When the first sinker 250 runs to the float cam, the first sinker 250 does not withdraw.

[0112] The float cam is arranged on the first path of the second sinker cam track 440. When the second sinker 260 runs to the float cam, the second sinker 260 does not withdraw. The withdrawal cam is arranged on the second path of the second sinker cam track 440, and it has a convex structure. When the second sinker 260 runs to this convex structure, the second sinker 260 withdraws outward to cooperate with yarn laying.

[0113] Through the above-mentioned sinker withdrawal cam 410 with an outward convex shape, the upper flanges 210 of the first sinker 250 and the second sinker 260 alternately withdraw outward from the outer circumference 500 of the cylinder; the substantially straight sinker float cam 420 allows the sinker float cam 420 to have a certain degree of floating, but it should still be within the range of the outer circumference 500 of the cylinder.

[0114] It should be noted that the cylinder is the core component of the knitting machine, which is cylindrical. A large number of needle grooves are evenly distributed on its outer surface (i.e., the outer circumference), which are used to install knitting needles. The outer circumference 500 of the cylinder refers to the outer circumferential surface of the cylinder, which is the track area for the up and down movement of the knitting needles and directly affects the accuracy of the loop formation process and the quality of the fabric.

[0115] See Figure 17a , as a preferred embodiment of the components of the present invention for a single-sided circular weft knitting machine, the knitting needle 100 includes a first knitting needle 150 and a second knitting needle 160, and the knitting needle cam track 300 includes a first knitting needle cam track 330 and a second knitting needle cam track 340;

[0116] The needle butt 140 of the first knitting needle 150 is arranged in the middle of the first knitting needle 150; the needle butt 140 of the second knitting needle 160 is arranged below the first knitting needle 150;

[0117] The first knitting needle cam track 330 is arranged above the second knitting needle cam track 340; the needle butt 140 of the first knitting needle 150 is embedded in the first knitting needle cam track 330, and the needle butt 140 of the second knitting needle 160 is embedded in the second knitting needle cam track 340.

[0118] As Figure 17aAs shown, the blue parts of the first knitting needle 150 and the second knitting needle 160 are the positions of the needle cams 140. It should be noted that the needle cam 140 of the first knitting needle 150 is embedded in the first knitting needle cam track 330, so that the first knitting needle 150 runs within the first knitting needle cam track 330; the needle cam 140 of the second knitting needle 160 is embedded in the second knitting needle cam track 340, so that the second knitting needle 160 runs within the second knitting needle cam track 340.

[0119] See Figure 17a , as a preferred embodiment of the components of the present invention for a single-sided circular weft knitting machine, the sinker 200 includes a first sinker 250 and a second sinker 260, and the sinker cam track 400 includes a first sinker cam track 430 and a second sinker cam track 440;

[0120] The heel 230 of the first sinker 250 is arranged in the middle of the first sinker 250, and the heel 230 of the second sinker 260 is arranged at the rear of the second sinker 260;

[0121] The first sinker cam track 430 is arranged inside the second sinker cam track 440; the heel 230 of the first sinker 250 is embedded in the first sinker cam track 430, and the heel 230 of the second sinker 260 is embedded in the second sinker cam track 440.

[0122] Figure 8 As shown, it is a schematic diagram of the first sinker 250 and its top view. The present invention uses two types of sinkers 200, Figure 8 The shape schematic of the first sinker 250 is shown in the lower part in the figure. Figure 8 The upper part is a schematic view from directly above the sinker 200. The yarn bending holding area and the heel 230 on the upper edge of the sinker 200 are respectively represented in red and green.

[0123] Figure 9 As shown, it is a schematic diagram of the second sinker 260 and its top view. The lower part in the figure is a schematic diagram of the shape of the second sinker 260. Figure 9 The upper part is a schematic view from directly above the sinker 200. The yarn bending holding area and the heel 230 on the upper edge of the sinker 200 are respectively represented in blue and orange.

[0124] See Figure 17a , Figure 19 and Figure 20 , as a preferred embodiment of the components of the present invention for a single-sided circular weft knitting machine, the first knitting needle 150 and the second knitting needle 160 are arranged alternately with m separated by n, where m and n are natural numbers greater than 0. m and n can be equal or unequal. When m ≠ n and it changes according to the pattern, it is a jacquard version of the interlaced plating stitch.

[0125] SeeFigure 19 As a preferred embodiment of the component of the present invention for a single-sided circular weft knitting machine, the first knitting needles 150 and the second knitting needles 160 are arranged alternately with one needle interval.

[0126] Preferably, the first knitting needles 150 and the second knitting needles 160 can also be arranged alternately with two needle intervals.

[0127] See Figure 17a 、 Figure 17b 、 Figure 19 and Figure 20 As a preferred embodiment of the component of the present invention for a single-sided circular weft knitting machine, the first sinker 250 and the second sinker 260 are arranged alternately with an interval of m needles and n needles, where m and n are natural numbers greater than 0. m and n can be equal or unequal. When m≠n and according to the pattern change, it is the jacquard version of the alternate plating stitch.

[0128] It should be noted that there is a corresponding relationship between the configuration of the knitting needles and the sinkers. For example, if the knitting needles are arranged alternately with an interval of m needles and n needles, the sinkers also need to be arranged alternately with an interval of m needles and n needles accordingly.

[0129] Since the rotation direction of the single-sided circular weft knitting machine is to the right, that is, the yarn is fed "from right to left", so the sinker corresponding to the left side of each knitting needle is the bending and sinking sinker of this knitting needle. As for which type of sinker it should be depends on whether this knitting needle is knitting the "face yarn" or the "plating yarn", and which type of sinker is used to cooperate with knitting the "face yarn" or the "plating yarn" according to the sinker cam configuration of this row.

[0130] As a preferred embodiment of the component of the present invention for a single-sided circular weft knitting machine, the values of m and n change according to the pattern (m and n can be equal or unequal, depending on the pattern), and the component for the single-sided circular weft knitting machine further includes a needle selection system, a sinker selection system and a pattern control system;

[0131] The needle selection system is used for the selection of knitting needles, the sinker selection system is used for the selection of sinkers, and the pattern control system is used to realize the linkage of the needle selection of knitting needles and the sinker selection according to the pattern.

[0132] It should be noted that when the values of m and n change according to the pattern (m and n can be equal or unequal, depending on the pattern), it is the jacquard version of the alternate plating stitch. By respectively configuring independent needle selection systems and sinker selection systems for the knitting needle system and the sinker system to select the knitting needles and sinkers, and through the pattern control system to realize the linkage of the needle selection of knitting needles and the sinker selection according to the pattern, the jacquard version knitting of the alternate plating stitch can be realized.

[0133] See Figure 19, as a preferred embodiment of the component of the present invention for a single-sided circular weft knitting machine, the first sinker 250 and the second sinker 260 are arranged alternately with one interval.

[0134] Preferably, the first sinker 250 and the second sinker 260 can also be arranged alternately with two intervals.

[0135] See Figure 17a 、 Figure 19 and Figure 20 , as a preferred embodiment of the component of the present invention for a single-sided circular weft knitting machine, the first needle cam track 330 includes the first path of the first needle cam track 330 and the second path of the first needle cam track 330, the second needle cam track 340 includes the first path of the second needle cam track 340 and the second path of the second needle cam track 340, the first sinker cam track 430 includes the first path of the first sinker cam track 430 and the second path of the first sinker cam track 430, and the second sinker cam track 440 includes the first path of the second sinker cam track 440 and the second path of the second sinker cam track 440;

[0136] The first path of the first needle cam track 330, the first path of the second needle cam track 340, the first path of the first sinker cam track 430, and the first path of the second sinker cam track 440 are configured in a matching manner;

[0137] The second path of the first needle cam track 330, the second path of the second needle cam track 340, the second path of the first sinker cam track 430, and the second path of the second sinker cam track 440 are configured in a matching manner.

[0138] It should be noted that the said matching configuration means synchronous configuration along the circumferential direction of the knitting machine to cooperate in controlling the movement of the needles and sinkers.

[0139] See Figure 17a 、 Figure 19 and Figure 20 , as a preferred embodiment of the component of the present invention for a single-sided circular weft knitting machine, the sinker cam corresponding to the first path of the first needle cam track 330 is set as the sinker retracting cam 410, the sinker cam corresponding to the first path of the second needle cam track 340 is set as the sinker floating cam 420, the needle cam corresponding to the first path of the first sinker cam track 430 is set as the needle tucking cam 310, and the needle cam corresponding to the first path of the second sinker cam track 440 is set as the needle non-dropping cam 320;

[0140] The sinker cam track corresponding to the second path of the first knitting needle cam track 330 is set as the sinker float cam 420, the sinker cam track corresponding to the second path of the second knitting needle cam track 340 is set as the sinker retraction cam 410, the knitting needle cam corresponding to the second path of the first sinker cam track 430 is set as the knitting needle non - dropping cam 320, and the knitting needle cam corresponding to the second path of the second sinker cam track 440 is set as the knitting needle tucking cam 310.

[0141] The process of the component of the present invention for a single - face circular weft knitting machine to produce an interlaced plating fabric is described as follows.

[0142] Figure 4 is the loop diagram of the interlaced plating stitch. Each loop is composed of two yarns. Therefore, a tucking cam is required to achieve this purpose. Only after passing through the tucking cam will there be two yarns in the needle hook 120.

[0143] Among the two yarns, one yarn is brought from the previous knitting path (the face yarn near the front of the fabric). To achieve this purpose, a non - dropping cam is required. Only after passing through the non - dropping cam can an unclosed loop arc be formed in the needle hook 120 and brought to the next knitting path.

[0144] Combined with the above discussion, the complete logic is as follows: Use the non - dropping cam to form a loop arc in the needle hook 120, and then use the tucking cam in the next knitting path to make this loop arc still remain in the needle hook 120, while hooking another yarn at the same time, so as to form a double - yarn plating loop with two yarns in the needle hook 120. That is to say, for the same knitting needle 100, the knitting needle 100 takes the non - dropping cam in the first knitting path, and needs to take the tucking cam in the second knitting path.

[0145] Since the entire fabric surface is composed of double - yarn plating loops and these loops are arranged in an interlaced configuration, it can be concluded that two types of knitting needles 100 are required. And the trajectories of these two types of knitting needles 100 in two knitting paths are exactly opposite, that is, the cam configurations of the two tracks in the front and back paths are swapped. From this, Figure 14 the shown needle cylinder cam configuration can be obtained. The needle cylinder cam is the core track component in the knitting machine that controls the movement of the knitting needle 100. It guides the knitting needle 100 to move up and down through a precisely designed concave - convex track, thereby completing actions such as knitting, tucking, and floating.

[0146] After solving the problem of the needle cylinder cam configuration, another problem needs to be considered: as Figure 15 shown, for the knitting needle 100 taking the non - dropping cam, since the purpose of non - dropping needs to be achieved, the needle tip of this knitting needle 100 needs to be higher than the lower edge 220 of the sinker 200, otherwise the old loop will drop, that is, the structure of the interlaced plating stitch cannot be obtained.

[0147] When the needle tip of the knitting needle 100 is higher than the lower edge 220 of the sinker 200, the following technical problems arise: Where is the yarn bending? That is, where does the yarn required for the subsequent loop formation of the knitting needle 100 that does not release the loop come from. The present invention ingeniously uses the upper edge 210 of the sinker 200 as the yarn bending holding surface for the knitting needle 100 that moves the non - loop - releasing cam.

[0148] As described above, the upper edge 210 of the sinker 200 usually has no function. However, since the needle tip of the knitting needle 100 that moves the non - loop - releasing cam is higher than the lower edge 220 and a yarn bending holding surface is required, the inventor of the present application uses the upper edge 210 of the sinker 200 as the yarn bending holding surface for the knitting needle 100 that moves the non - loop - releasing cam, thus solving the above - mentioned problem.

[0149] So far, there is still a problem to be solved to achieve the knitting of the alternate plating stitch: After observing Figure 4 the organizational structure, it can be seen that for the same yarn, it is hooked by the knitting needle 100 that moves the tuck cam as plating yarn on the odd - numbered knitting needles 100, and is hooked by the knitting needle 100 that moves the non - loop - releasing cam as face yarn on the next knitting needle 100, that is, the even - numbered needle.

[0150] For the knitting needle 100 that moves the tuck cam, yarn bending is required on the lower edge 220 of the sinker 200; for the knitting needle 100 that moves the non - loop - releasing cam, yarn bending is required on the upper edge 210 of the sinker 200. The upper edge 210 is relatively small. When the upper edge 210 is required to be the yarn bending holding surface for the knitting needle 100 that moves the non - loop - releasing cam, this holding surface must be directly above the knitting needle 100. The lower edge 220 of the sinker 200 is very long, and each position can be used as the yarn bending holding surface for the tuck knitting needle 100. Due to the coil staggered configuration relationship presented by the organizational structure, Figure 4 in which the coils exist in an alternating pattern with a 1 - in - 1 interval. Therefore, the inventor designs the sinker 200 to have two types of heel positions 230, that is, there are two types of sinkers 200. They are arranged in a 1 - in - 1 pattern. Their head structures and sizes are the same, and the difference lies in the positions of the heels 230, so that two different sinker cam tracks 400 can be used to control the entry and exit of the sinker 200. When the lower edge 220 is required to be the yarn bending holding surface, the sinker 200 is withdrawn outward. At this time, the yarn is laid on the lower edge 220 of the sinker 200; when the upper edge 210 is required to be the yarn bending holding surface, the sinker 200 is kept in the inner position, so that the yarn can be laid on the upper edge 210 of the sinker 200. The above configuration solves the problems of the configuration and trajectory control of the sinker 200. The two types of sinkers 200 are as Figure 8 、 Figure 9 shown, and the sinker 200 configuration and the sinker cam track 400 configuration are as Figure 16 shown.

[0151] As described above, explanations have been made for Figure 14 , Figure 15 , Figure 16 . Figures 14 - 16 shows the configuration diagram of the knitting needle 100 and the cylinder cams, as well as the configuration of the sinker 200 and the sinker cam track 400. The cooperative working state of the sinker 200 and the knitting needle 100 as shown in Fig. 17 can be obtained.

[0152] When using the components of the present invention for a single-sided circular weft knitting machine to produce an intarsia fabric, its complete loop formation process is divided into a total of 5 stages, namely I, II, III, IV, and V. The following combines Figure 14 , Figure 16 , Figure 17a and Figure 17b to elaborate on the loop formation process for each stage in detail.

[0153] I. The first track:

[0154] Stage I: The knitting needle 100 moves along the tuck cam. There is a loop arc (red) brought from the previous knitting course in the needle hook 120, and an intarsia coil composed of two red and blue yarns remains on the needle tongue 130 outside the needle hook 120 (blue on top and red at the bottom).

[0155] Stage II: After the climbing stage of the tuck cam, the red loop arc brought from the previous course still remains on the needle tongue 130, while the old loop is outside the needle hook 120 and on the needle tongue 130 after passing through the non - doffing cam of the previous knitting course. After the knitting needle 100 climbs, it retreats to the needle bar 110 again (blue on top and red at the bottom).

[0156] Stage III: Subsequently, the knitting needle 100 descends to hook a new yarn (blue). At the same time, the first sinker 250 withdraws outward to cooperate with yarn laying. It should be noted that the first sinker 250 needs to be configured on the left side of the first knitting needle 150 because when the first sinker 250 withdraws, the new yarn will be laid on the lower blade edge 220 of the sinker 200, as Figure 10 shown. Then the newly hooked blue yarn will be above the old yarn (red) in the needle hook 120. Subsequently, the knitting needle 100 further descends, and the old loop flips over the needle tip of the knitting needle 100 and is strung over the two new red and blue yarns. Due to the stringing, the loop arcs of the two new yarns thus form a closed loop. After passing through the first path of the first knitting needle cam track 330 and the first sinker cam track 430, there are two newly formed double - loops (blue on top and red at the bottom) in the needle hook 120.

[0157] Stage IV: After the end of Stage III, the knitting needle 100 then enters the next path, and the knitting needle 100 moves along the non - dropping - stitch cam. The old loops (red and blue double loops, blue on top and red below) originally brought from the previous knitting path are in the needle hook 120. After passing through the ascending stage (loop - doffing process) of the non - dropping - stitch cam, they retreat to the needle bar 110 (blue on top and red below).

[0158] Stage V: Subsequently, the knitting needle 100 descends to hook a new yarn (red), but the first sinker 250 does not retract during the yarn - laying process. It should be noted that the first sinker 250 needs to be arranged on the left side of the first knitting needle 150. Since the first sinker 250 does not retract at this time, the new yarn will be laid on the upper beak 210 of the sinker 200 (i.e., Figure 9 the blue area shown), as Figure 11 shown. Subsequently, the knitting needle 100 further descends, and the new yarn bends on the upper beak 210 of the sinker 200. Since the non - dropping - stitch cam is arranged here, the old loops brought from the previous knitting path do not pass over the tip of the knitting needle 100, but still remain on the latch 130 (blue below and red above). The red new yarn cannot form a closed loop because it is not looped through. After passing through the second path of the first knitting - needle triangular runway 330 and the first sinker triangular runway 430, only the loop arc formed by the red new yarn is in the needle hook 120, while the old loops are still on the latch 130 (outside the needle hook 120, blue on top and red below). At this point, it returns to the initial state I.

[0159] II. The Second Runway:

[0160] Stage I: The knitting needle 100 moves along the non - dropping - stitch cam, and there is an old loop (red on top and blue below) brought from the previous knitting path in the needle hook 120.

[0161] Stage II: After passing through the loop - doffing stage of the non - dropping - stitch cam, the old loop (red on top and blue below) retreats to the needle bar 110 through the loop - doffing process.

[0162] Stage III: Subsequently, the knitting needle 100 descends to hook a new yarn (blue), but the second sinker 260 does not retract during the yarn - laying process. It should be noted that the second sinker 260 needs to be arranged on the left side of the second knitting needle 160. When the second sinker 260 does not retract, the new yarn will be laid on the upper beak 210 of the sinker 200 (i.e., Figure 9(in the shown blue area), subsequently, the knitting needle 100 further descends, and the new yarn is bent over the upper blade edge 210 of the sinker 200. Since the no-dropping cam is configured here, the old loop brought from the previous knitting course does not pass over the tip of the knitting needle 100 but remains on the latch 130 (red on top, blue below). The blue new yarn can only form an unclosed loop arc instead of a closed loop because it is not looped through. After the first pass through the second knitting needle cam track 340 and the second sinker cam track 440, only the loop arc formed by the blue new yarn is in the hook 120, while the old loop is still on the latch 130 (outside the hook 120, red on top, blue below).

[0163] Stage IV: After the end of Stage III, subsequently, the knitting needle 100 enters the next pass, and the knitting needle 100 moves along the tuck cam. The blue loop arc brought from the previous knitting course remains on the latch 130 after passing through the ascending stage of the tuck cam, while the old loop retreats to the needle shank 110 again (red on top, blue below).

[0164] Stage V: Subsequently, the knitting needle 100 descends to hook the new yarn (red). At the same time, the second sinker 260 retracts outward to cooperate with yarn feeding. It should be noted that the second sinker 260 needs to be configured on the left side of the second knitting needle 160. Since the second sinker 260 has retracted, the new yarn will be laid on the lower blade edge 220 of the sinker 200. Then the newly fed red yarn will be above the old yarn (blue) in the hook 120. Subsequently, the knitting needle 100 further descends, and the old loop passes over the tip of the knitting needle 100 and is looped through the two new blue and red yarns. The loop arcs of the two new yarns form closed loops due to the looping. After the second pass through the second knitting needle cam track 340 and the second sinker cam track 440, there are double loops newly formed by two yarns in the hook 120 (red on top, blue below). Thus, it returns to the initial state I.

[0165] The summary of the above loop formation process is as follows:

[0166] (1) The present invention utilizes the no-dropping cam to cooperate with the movement of the sinker 200 to bend the yarn over the upper blade edge 210 of the sinker 200 to form a face yarn loop arc.

[0167] (2) In this embodiment, the two types of knitting needles 100 and the two types of sinkers 200 are arranged in a 1-in-1 pattern. The two types of sinkers 200 are respectively controlled by the two sinker cam tracks 400 to alternately bend the yarn over the upper blade edge 210 and the lower blade edge 220 of the sinker 200 to form a face yarn loop arc and an inlay yarn loop arc respectively. At the same time, the two types of knitting needles 100 corresponding to the two types of sinkers 200 respectively move along the no-dropping cam and the tuck cam in sequence to form a face yarn pre-bent yarn or an inlay yarn loop respectively.

[0168] (3) Using the tuck cam, the loop arc of the ground yarn still remains in the needle hook 120. After hooking a new yarn again, the new yarn is located above the loop arc of the ground yarn. Then, after loop shedding, the ground yarn is on the front side of the fabric, while the newly hooked yarn is on the back side of the fabric, and its role is plating yarn. The yarn hooked for the second time and the yarn hooked for the first time together form a double loop, which is a plating relationship.

[0169] (4) Whenever entering the next knitting course, the movement trajectories of the knitting needles 100 and the sinkers 200 reverse. The needles that originally knitted tucks now move along a non-loop-shedding trajectory, hooking a new yarn to form a loop arc of the ground yarn; while the knitting needles that originally moved along a non-loop-shedding trajectory now move along a tuck trajectory, hooking a second yarn and forming a plating double loop together with the loop arc of the ground yarn already in the needle hook 120.

[0170] (5) The double loops formed on the odd-numbered knitting needles 100 are always blue on top and red on the bottom, that is, the red yarn acts as the ground yarn; while the double loops formed on the even-numbered knitting needles 100 are always red on top and blue on the bottom, that is, the blue yarn acts as the ground yarn.

[0171] (6) For the same yarn, its knitting role changes with the trajectory changes of the knitting needles 100 and the sinkers 200. When the yarn bends over the upper edge 210 of the sinker 200 to form a loop arc of the ground yarn, the yarn acts as the ground yarn at this time; and when it comes to the next knitting needle 100 and the yarn bends over the lower edge 220 of the sinker 200 to form a plating loop arc, the yarn acts as the plating yarn at this time, and so on. The same yarn 1 alternates as the ground yarn and the plating yarn every other one. The blue yarn appears as the plating yarn on the odd-numbered needles and as the ground yarn on the even-numbered needles; while the red yarn appears as the ground yarn on the odd-numbered needles and as the plating yarn on the even-numbered needles. The same yarn appears as the ground yarn and the plating yarn on the odd-numbered and even-numbered knitting needles 100 in turn. At the same time, the role presented by the other yarn is exactly the opposite. This is the meaning of interlaced plating.

[0172] Preferably, by changing the height H1 of the upper edge 210 of the sinker 200 and the lowering height H2 of the knitting needles 100 that do not shed loops, the length L of the pre-bent ground yarn can be changed, thereby changing the length ratio of the ground yarn loops and the plating yarn loops. Different length ratios of the ground yarn and plating yarn loops can endow the fabric with different lateral and longitudinal elasticities, especially having a greater impact on the lateral elasticity. Generally speaking, the longitudinal elasticity of such fabrics is very small, but the lateral elasticity can vary within a certain range. Therefore, the lateral elasticity of the fabric can be changed by changing H1 and H2 according to different demand scenarios, as Figure 15 shown.

[0173] It should be noted that generally, the height H1 of the upper blade edge 210 of the sinker 200 is greater than the descending height H2 of the non - looping knitting needle, that is, H1 > H2. At this time, the pre - bending of the face yarn is completed between the upper blade edge 210 of the sinker 200 and the needle hook 120 of the non - looping knitting needle. The upper blade edge 210 of the sinker 200 and the needle hook 120 of the non - looping knitting needle are the two bending points for the yarn to be bent. However, the descending height H2 of the non - looping knitting needle may also be greater than the height H1 of the upper blade edge 210 of the sinker 200, that is, H2 > H1, which means the needle hook 120 of the knitting needle 100 is higher than the upper blade edge 210 of the sinker 200. At this time, the pre - bending of the face yarn is still completed relying on the upper blade edge 210 of the sinker 200. Only at this time, the pre - bending of the face yarn is completed between the upper blade edge 210 of the sinker 200 and the needle hook 120 of the tuck - knitting needle. The upper blade edge 210 of the sinker 200 and the needle hook 120 of the tuck - knitting needle are the two bending points for the yarn to be bent. That is, by using the needle hook 120 of the tuck - knitting needle as another bending point for the yarn to be bent.

[0174] The standard process configuration of the components for a single - face circular weft knitting machine of the present invention Figure 19 As shown, in this standard configuration, the two types of sinkers 200 and the two types of knitting needles 100 are arranged in a 1 - in - 1 pattern.

[0175] In fact, the configuration of the two types of sinkers 200 and the two types of knitting needles 100 can also be changed. For example, it can be changed from a 1 - in - 1 pattern to a 2 - in - 2 pattern, that is, the process configuration is as Figure 20 shown, and the fabric loop diagram produced using this configuration is as Figure 18 shown.

[0176] Figure 18 The structure shown also has the characteristics of the interlaced plating structure. However, due to the different numbers and positions of the cross - laid yarns, new characteristics will be given to the fabric. By analogy, changing the arrangement of the sinkers 200 and the knitting needles 100 will result in other changing structures.

[0177] As described above, the components for a single - face circular weft knitting machine of the present invention have the following advantages:

[0178] 1. By making the knitting needle 100 move along the non - loop - dropping cam and combining with the track of the sinker 200 that does not retract, the yarn is bent on the upper sinker edge 210 of the sinker 200 without dropping the loop, thereby forming a face - yarn loop arc, preparing for hooking the second yarn later to form a plating loop together. Since the old loop is held in the throat 240 of the sinker 200, if the face - yarn is also bent on the lower sinker edge 220 of the sinker 200, because the needle tip is lower than the lower sinker edge, the old loop will surely be dropped, and instead of forming a face - yarn loop arc, it will directly form a loop. The present invention ingeniously uses the upper sinker edge 210 of the sinker 200 as the bending support surface for the face - yarn, and uses the height difference between the upper sinker edge 210 and the lower sinker edge 220 of the sinker 200 to form the required pre - bent length of the face - yarn on the knitting needle 100. Since the height of the knitting needle 100 is higher than the lower sinker edge 220 of the sinker 200, the old loop will not be dropped, preparing for the subsequent formation of the plating loop.

[0179] 2. The present invention uses two types of sinkers 200. By configuring two sinker cam tracks 400 to control the movement tracks of the two types of sinkers 200 respectively, and adding the interlaced configuration of tuck cams and non - loop - dropping cams, the knitting needle 100 works alternately in the states of pre - bending the face - yarn and forming the plating loop, and the yarn alternately appears as the face - yarn and the plating yarn. This alternately presented plating loop and the cross - presented extension line endow the fabric with new characteristics, namely, very small longitudinal elasticity and certain lateral elasticity, filling a gap in weft - knitted fabrics.

The protection scope of the present invention is defined by the appended claims. Without departing from the principle and essence of the present invention, those skilled in the art can make various changes or modifications to these embodiments, but these changes and modifications all fall within the protection scope of the present invention.
