Description

Technical Field

[0001] This invention relates to a warp-knitted fabric with a cable knit structure similar to that of a flat knitting machine and its manufacturing process, belonging to the field of textile technology. Background Technology

[0002] With the development of society and the economy and the improvement of people's living standards, people are no longer satisfied with traditional, monotonous clothing patterns and fabrics, but instead pursue comfortable, functional, and fashionable clothing fabrics. Traditional patterned sweaters are mainly knitted on flat knitting machines. By transferring needles, effects such as eyelets, raised loops, and twisted loops can be created. Distributing these structures on the surface of the knitted fabric according to certain rules forms patterns. The basic characteristics of transfer knitting depend mainly on the basic structure that forms it. However, the eyelets, raised loops, and twists created by continuous multiple transfers or transfers across large needle lengths can affect the fabric's strength, abrasion resistance, pilling, and snagging properties. During wear, the fabric is prone to pilling, deformation, and holes. Flat knitting machines have a relatively smaller output compared to warp knitting machines and circular knitting machines, making it difficult to meet demand when orders are large.

[0003] Because warp-knitted fabrics also have a loop structure, they combine the dimensional stability of woven fabrics with the comfort of knitted fabrics. Furthermore, warp knitting machines have a wider width and a much higher output than flat knitting machines and circular knitting machines. Therefore, there is an urgent need to develop a warp-knitted fabric with a cable knit structure similar to that of flat knitting machines, and its production process. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a warp-knitted fabric with a simulated flat knitting cable knit structure and a production process. On the reverse side of the process, a simulated flat knitting cable knit structure is formed by combining pressing yarn structure, padding structure, different warp cycles, and padding yarn numbers to float on the reverse side of the fabric. The chain braiding structure woven by guide bar GB3 and the weft weft weaving structure woven by guide bar GB4 form the base fabric, which respectively enhances the warp and weft strength of the fabric.

[0005] The first objective of this invention is to provide a production process for a warp-knitted fabric with a cable knit structure, comprising the following steps:

[0006] Step 1: Material Selection: Select wool and cashmere blended yarn, cotton yarn, paper yarn, polyester, nylon, fancy yarn, metallic yarn, and sequin yarn as raw materials;

[0007] Step 2, Warping: The polyester filament and cotton yarn are warped on the warping machine according to the requirements of width, warp density and yarn threading rate, with a certain number of warp heads.

[0008] Step 3, Weaving: Weaving is carried out using a warp knitting machine;

[0009] Step 4, Finishing: Dyeing, finishing, and setting;

[0010] The selection and arrangement of the guide bar structures and yarn threading methods during warping and weaving include the following two types:

[0011] The first method for selecting and matching the structure of each comb bar and the threading method is as follows:

[0012] Comb GB1: 1-0 / 1-1 / 1-2 / 1-1 / / Eight holes and one thread;

[0013] Comb GB2: 1-0 / 2-3 / 1-0 / 1-2 / / Three-hole, one-through, one-hole, one-through, three-hole;

[0014] Comb GB3: 0-1 / 1-0 / / Full wear;

[0015] Comb GB4: 3-3 / / 0-0 / / Full wear;

[0016] The second method for selecting and matching the various comb structures and threading the yarn is as follows:

[0017] Comb GB1: 1-0 / 1-1 / 2-3 / 2-2 / / Eight holes and one thread;

[0018] Comb GB2: 1-0 / 3-4 / 1-0 / 2-3 / / Three-hole, one-through, one-hole, one-through, three-hole;

[0019] Comb GB3: 0-1 / 1-0 / / Full wear;

[0020] Comb GB4: 3-3 / / 0-0 / / Full wear.

[0021] In one embodiment of the present invention, the warp-knitted imitation flat knitting cable knit structure fabric is woven on a four-comb Raschel warp knitting machine with a yarn pressing mechanism, and a total of four combs are configured: comb GB1, comb GB2, comb GB3, and comb GB4; there are two combs in front of the yarn pressing plate; wherein comb GB1 weaves the yarn pressing structure in odd-numbered rows and the padding structure in even-numbered rows; comb GB2 weaves the yarn pressing structure; comb GB3 weaves the chain braiding structure; and comb GB4 weaves the weft insertion structure.

[0022] In one embodiment of the present invention, the odd-numbered rows of the guide bar GB1 form a pressing yarn structure, and the even-numbered rows form a missing pad structure; the guide bar GB2 weaves the pressing yarn structure; when the pressing guide bar completes the needle padding and return machine, the pressing plate descends, pressing the pressing yarn that has just been padded down onto the needle bar. The pressing yarn structure does not form loops, but the yarn loops are wrapped around the base of the ground structure. The pressing yarn structure floats on the reverse side of the fabric process, presenting a three-dimensional effect, and the loops that should originally be arranged along the warp direction of the fabric are rotated 90 degrees to the left and lie flat.

[0023] In one embodiment of the invention, the guide bars GB1 and GB2 are woven with a herringbone pattern protruding on the reverse side of the fabric. The herringbone pattern on the left side of a repeating unit is thicker than that on the right side. This thicker herringbone pattern is woven by guide bars GB1. After weaving the pressing structure in an odd number of rows, there is a gap in the next row, and the extension line crosses three rows, making the herringbone pattern appear thicker. The thinner herringbone pattern on the right side of the repeating unit is woven by guide bars GB2. By changing the yarn threading and padding numbers, a more three-dimensional and more complex structure is formed.

[0024] In one embodiment of the present invention, the twisted yarn structure with different transfer methods is simulated by changing the direction of the padding yarn of the pressing yarn structure and the ground yarn structure and the open / closed loop shape of the pressing yarn structure; when the pressing yarn structure and the ground yarn structure are padded in opposite directions, the loop shape is a figure-eight structure. When the pressing yarn structure is a closed loop, the extension line of the next horizontal row is pressed on the upper horizontal row extension line; when the pressing yarn structure is an open loop, the extension line of the upper horizontal row is pressed on the lower horizontal row extension line.

[0025] In one embodiment of the present invention, the chain braiding structure woven by the GB3 comb and the weft weft wefting structure woven by the GB4 comb form the base fabric, which are used to enhance the warp and weft strength of the fabric, respectively. The fabric thickness is increased or decreased by increasing or decreasing the padding yarn number of the weft ...

[0026] In one embodiment of the present invention, the yarn and comb are configured as follows: combs GB1 and GB2 are made of paper yarn, and combs GB3 and GB4 are made of recycled polyester and recycled viscose; or the yarn and comb are configured as follows: combs GB1 and GB2 are made of paper yarn, cotton yarn, or cashmere yarn, and combs GB3 and GB4 are made of polyester and nylon; or the yarn and comb are configured as follows: combs GB1 and GB2 are made of cashmere yarn, and combs GB3 and GB4 are made of polyester and cotton yarn.

[0027] In one embodiment of the present invention, the method further includes step five: detection and packaging.

[0028] The second objective of this invention is to provide a warp-knitted imitation flat knitting cable knitting fabric prepared according to the aforementioned production process of such a fabric.

[0029] The third objective of this invention is to provide clothing and home textiles containing the aforementioned warp-knitted imitation flat knit cable knit structure fabric.

[0030] The beneficial effects of this invention are as follows:

[0031] 1. This invention utilizes a high-speed Raschel warp knitting machine with a large width and high rotation speed for production. Compared with computerized flat knitting machines, the production efficiency and output are greatly increased. For the same output, the required equipment floor space, manpower, and time are significantly reduced, which can meet the needs of large orders and large output, and bring better economic benefits to enterprises.

[0032] 2. This invention utilizes guide bars GB1 and GB2 to form a pressing structure and a missing pad structure, and guide bars GB3 and GB4 to form a chain braiding structure and a weft insertion structure, respectively. Since the pressing structure, the missing pad structure, and the weft insertion structure are not looped, the pressing structure is wrapped around the base of the ground structure in a loop shape, the missing pad structure hangs straight on the reverse side of the fabric, and the weft insertion structure turns at the junctions of the horizontal rows of ground structures without bending into loops. Unlike the yarn in a flat knitting machine's cable knit structure, which requires transfer and stretching through elastic expanders, the yarn in a warp-knitted pressing structure does not require complex and specialized machinery for loop transfer, and it doesn't even need to be bent into loops. Therefore, a wider variety of raw materials can be used, such as low-strength, high-hair cashmere and wool staple yarns, cotton yarns, and coarser-count plied yarns, fancy yarns, and metallic threads.

[0033] 3. This invention utilizes a warp-knitted pressing structure, unlike the cable knit structure of a flat knitting machine which requires frequent loop transfers. When the loop transfer span is large or the number of consecutive loop transfers is high, the stress on each loop is uneven, and the tension is concentrated on the tensioned loop, easily causing holes. Furthermore, the presence of holes, loop protrusions, and twisting at the loop transfer points can affect the fabric's strength, abrasion resistance, pilling, and snagging. The warp-knitted pressing structure uses four guide bars for knitting. Guide bars GB3 and GB4 respectively weave chain braiding and weft insertion structures, enhancing the warp and weft strength of the fabric. The pressing structures woven by guide bars GB1 and GB2 float on the reverse side of the fabric process. When the yarn threading rate is high, the connection between the structures is tighter. Compared to the cable knit structure of a flat knitting machine, the mechanical properties of the warp-knitted pressing structure fabric are superior, and different functional fabrics can be obtained through different yarn combinations, yarn threading cycles, and yarn padding numbers.

[0034] 4. This invention utilizes a combination of pressing yarn structure and missing pad structure to form herringbone pattern. By changing the padding yarn number, warp loop, and open / closed loop shape of the pressing yarn structure, different thicknesses and styles of herringbone pattern can be formed. Compared with the cable knit structure of flat knitting machine, it is more convenient to weave and the pattern effect is more three-dimensional. Attached Figure Description

[0035] To more clearly illustrate the technical solutions in the embodiments of the present invention, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0036] Figure 1 A physical image of a warp-knitted fabric with a cable knit structure similar to that of a flat knitting machine, provided for this invention;

[0037] Figure 2 The present invention provides a diagram showing the movement of the yarn padding of the comb bars GB1 to GB4 for a warp-knitted fabric with a cable knit structure similar to that of a flat knitting machine.

[0038] Figure 3 The diagram shows the loop structure when the yarn is padded in the same direction and in the opposite direction during the pressing weave. Detailed Implementation

[0039] The invention is described in detail below. In the following paragraphs, different aspects of the embodiments are defined in more detail. The aspects so defined may be combined with any other aspect or aspects unless explicitly stated otherwise. In particular, any feature considered preferred or advantageous may be combined with one or more other features considered preferred or advantageous.

[0040] Example 1:

[0041] like Figure 1-3 As shown, the present invention provides a production process for a warp-knitted fabric with a cable knit structure, comprising the following steps:

[0042] Step 1: Material Selection: Select wool and cashmere blended yarn, cotton yarn, paper yarn, polyester, nylon, fancy yarn, metallic yarn, and sequin yarn as raw materials;

[0043] Step 2, Warping: The polyester filament and cotton yarn are warped on the warping machine according to the requirements of width, warp density and yarn threading rate, with a certain number of warp heads.

[0044] Step 3, Weaving: Weaving is carried out using a four-comb Raschel warp knitting machine with a yarn pressing mechanism;

[0045] Step 4, Finishing: Dyeing, finishing, and setting;

[0046] Step 5: Testing and packaging;

[0047] The selection and arrangement of the guide bar structures and yarn threading methods during warping and weaving include the following two types:

[0048] The first method for selecting and matching the structure of each comb bar and the threading method is as follows:

[0049] Comb GB1: 1-0 / 1-1 / 1-2 / 1-1 / / Eight holes and one thread;

[0050] Comb GB2: 1-0 / 2-3 / 1-0 / 1-2 / / Three-hole, one-through, one-hole, one-through, three-hole;

[0051] Comb GB3: 0-1 / 1-0 / / Full wear;

[0052] Comb GB4: 3-3 / / 0-0 / / Full wear;

[0053] The second method for selecting and matching the various comb structures and threading the yarn is as follows:

[0054] Comb GB1: 1-0 / 1-1 / 2-3 / 2-2 / / Eight holes and one thread;

[0055] Comb GB2: 1-0 / 3-4 / 1-0 / 2-3 / / Three-hole, one-through, one-hole, one-through, three-hole;

[0056] Comb GB3: 0-1 / 1-0 / / Full wear;

[0057] Comb GB4: 3-3 / / 0-0 / / Full wear.

[0058] The use of chain braiding in GB3 combing can enhance the longitudinal dimensional stability of the fabric, while the use of weft weaving in GB4 combing can not only enhance the transverse dimensional stability of the fabric, but also change the fabric weight, porosity and thickness by varying the amount of needle back transverse displacement.

[0059] Optionally, the Raschel warp knitting machine with a yarn pressing mechanism is RS4 / 2F.

[0060] Optionally, the yarn and comb are configured such that comb GB1 and comb GB2 are made of paper yarn, and comb GB3 and comb GB4 are made of recycled polyester and recycled viscose.

[0061] Optionally, the yarn and comb are configured such that: comb GB1 and comb GB2 are made of paper yarn, cotton yarn, or cashmere yarn, and comb GB3 and comb GB4 are made of polyester or nylon.

[0062] Optionally, the yarn and comb are configured such that comb GB1 and comb GB2 are made of cashmere yarn, and comb GB3 and comb GB4 are made of polyester or cotton yarn.

[0063] The yarn padding movement of the guide bars (GB1 to GB4) in warp-knitted fabrics with a cable knit structure similar to those of a flat knitting machine is as follows: Figure 2 As shown:

[0064] First, the odd-numbered rows of the guide bar GB1 form the pressing yarn structure, and the even-numbered rows form the missing pad structure; the guide bar GB2 weaves the pressing yarn structure; when the pressing yarn guide bar completes the needle padding and return machine, the pressing plate descends, pressing the pressing yarn that has just been padded down onto the needle bar. Therefore, the pressing yarn structure does not form loops, but rather forms loops wrapped around the base of the ground structure. Visually, the pressing yarn structure is obviously floating on the reverse side of the fabric process, presenting a three-dimensional effect, and the loops that should originally be arranged along the warp direction of the fabric are rotated 90 degrees to the left and lie flat.

[0065] The herringbone pattern protruding on the reverse side of the fabric is woven by guide bars GB1 and GB2. The herringbone pattern on the left side of a repeating unit is thicker than that on the right side. This thicker herringbone pattern is woven by guide bars GB1. After weaving the pressing structure in odd-numbered rows, padding is omitted in the next row, and the extension line crosses 3 rows, making the herringbone pattern appear thicker. The thinner herringbone pattern on the right side of the repeating unit is woven by guide bars GB2. By changing the yarn threading and padding numbers, a more three-dimensional and more complex structure is formed.

[0066] By changing the direction of the padding yarn in the pressing and ground structures, as well as the opening and closing loop shape of the pressing structure, different loop transfer methods of the cable knit structure can be simulated. For example... Figure 3 As shown, the loop shape when the backing yarn and the ground yarn are backed up in reverse is sometimes called the figure-eight structure. When the backing yarn is a closed loop, the extension line of the next row overlaps the extension line of the previous row; when the backing yarn is an open loop, the extension line of the previous row overlaps the extension line of the next row.

[0067] The chain stitch weave of GB3 and the weft insertion weave of GB4 form the base fabric, which are used to enhance the warp and weft strength of the fabric, respectively. The thickness of the fabric can be increased or decreased by adding or removing the padding yarns of the weft insertion weave. Visually, the front side of the fabric shows the interlocking loops of the chain stitch weave and the inner weft insertion weave, which is relatively flat and regular compared to the reverse side of the fabric.

[0068] According to the technical solution provided by this invention, the warp-knitted imitation flat knitting cable knit structure fabric is woven on a four-comb Raschel warp knitting machine with a yarn pressing mechanism, and a total of 4 combs are configured: comb GB1, comb GB2, comb GB3, and comb GB4; there are 2 combs in front of the yarn pressing plate; wherein comb GB1 weaves the yarn pressing structure in odd-numbered rows and the padding structure in even-numbered rows; comb GB2 weaves the yarn pressing structure; comb GB3 weaves the chain braiding structure; and comb GB4 weaves the weft insertion structure.

[0069] Example 2:

[0070] A warp-knitted fabric with a cable knit structure, comprising the following percentages by weight: 27.3% 16S / 4 paper yarn, 25.6% 8.3tex cotton single yarn, and 47.1% 150D / 72f semi-dull recycled polyester DTY.

[0071] The production process of this fabric is as follows: The specific flow of each process is as follows: including selection and matching of the guide bar structure, preparation, warping, weaving, and finishing. The specific steps of the fabric production process are as follows:

[0072] Step 1, Material Selection: 16S / 4 paper yarn, 8.3tex cotton single yarn, and 150D / 72f semi-dull recycled polyester DTY are selected as raw materials;

[0073] Step 2, Warping: Based on a width of 150cm and a horizontal density of 4.0wpc, the warp threading of GB1 combs is 8 gaps and 1 thread, the warp threading of GB2 combs is 3 gaps, 1 thread, 1 gap, 1 thread, and 3 gaps, and the warp threading of GB3 and GB4 combs is full threading; the calculated warp threading head count is 34 for GB1 combs, 67 for GB2 combs, and 300 for GB3 and GB4 combs.

[0074] The temperature at the warping site is 25±1℃ and the relative humidity is 65±5%. The relatively high and stable temperature and humidity help stabilize the twist of the polyester yarn and make the surface soft, preventing the yarn from getting tangled and which is beneficial to the production of warp-knitted products.

[0075] Step 3, Weaving: Weaving is carried out using a single-needle bed Raschel warp knitting machine with a pressure plate;

[0076] Model: Raschel warp knitting machine RS4 / 2F

[0077] Model number: 9-pin

[0078] Width: 130 inches

[0079] Warp knitting structure and yarn threading method:

[0080] Comb GB1: 1-0 / 1-1 / 1-2 / 1-1 / / 8 gaps 1 pass-through;

[0081] Comb GB2: 1-0 / 2-3 / 1-0 / 1-2 / / 3 empty 1 through 1 empty 1 through 3 empty;

[0082] Comb GB3: 0-1 / 1-0 / / Full wear;

[0083] Comb GB4: 3-3 / 0-0 / / Full wear;

[0084] raw material:

[0085] Comb GB1, Comb GB2: 16S / 4 paper yarn ply

[0086] Combing GB3: 8.3tex cotton single yarn,

[0087] Comb bar GB4: 150D / 72f semi-dull polyester DTY;

[0088] Input the weaving pattern, warp feed amount, and draft density into the computer display screen of the control cabinet, save the data, load the machine file, and then start the machine. After weaving, the raw fabric is obtained, weighed, bagged, and stored in the warehouse.

[0089] Step 4, Finishing: Dyeing, finishing, setting, etc.;

[0090] Step 5: Testing and packaging.

[0091] Through the above processes, a warp-knitted fabric with a simulated flat knit cable knit structure, as described in this embodiment, can be obtained. Made from environmentally friendly paper yarn, the fabric itself possesses a wrinkled and sophisticated feel. The pressed yarn structure woven from the paper yarn floats on the reverse side of the fabric, creating a rich, three-dimensional pattern effect similar to a flat knit cable knit structure. The weft-insertion structure woven from recycled polyester is wear-resistant, has less fuzz, and strengthens the lateral connections of the fabric. Different patterns can be achieved by combining different yarn-threading cycles and yarn-insertion techniques. The environmentally friendly paper yarn and recycled polyester are more environmentally friendly and meet the current requirements of energy conservation and emission reduction. This warp-knitted fabric with a simulated flat knit cable knit structure can be used for home textiles such as cushions and sofa cushions.

[0092] Example 3:

[0093] A warp-knitted fabric with a cable knit structure, comprising the following percentages by weight: 9.35% 32S / 5 paper yarn, 19.34% 40S / 4 vortex spun cotton yarn, 27.35% 50D36f semi-dull polyester, and 43.97% 75D / 36f semi-dull polyester DTY.

[0094] The production process of this material is as follows: The specific flow of each process is as follows: including selection and matching of the guide bar structure, preparation, warping, weaving, and finishing. The specific steps of the fabric production process are as follows:

[0095] Step 1, Material Selection: Use 32S / 5 paper yarn, 40S / 4 vortex spun cotton yarn, and 75D / 36f semi-dull polyester DTY as raw materials;

[0096] Step 2, Warping: Based on a width of 150cm, a horizontal density of 7.0wpc, the warp threading of GB1 combs is 8 gaps and 1 thread, the warp threading of GB2 combs is 3 gaps, 1 thread, 1 gap, 1 thread, and 3 gaps, and the warp threading of GB3 and GB4 combs is full thread; the calculated warp threading head count is 39 for GB1 combs, 78 for GB2 combs, and 350 for GB3 and GB4 combs.

[0097] The temperature at the warping site is 25±1℃ and the relative humidity is 65±5%. The relatively high and stable temperature and humidity help stabilize the twist of the polyester yarn and make the surface soft, preventing the yarn from getting tangled and which is beneficial to the production of warp-knitted products.

[0098] Step 3, Weaving: Weaving is carried out using a single-needle bed Raschel warp knitting machine with a pressure plate;

[0099] Model: Raschel warp knitting machine RS4 / 2F

[0100] Model number: 16 pins

[0101] Width: 130 inches

[0102] Warp knitting structure and yarn threading method:

[0103] Comb GB1: 1-0 / 1-1 / 1-2 / 1-1 / / 8 gaps 1 pass-through;

[0104] Comb GB2: 1-0 / 2-3 / 1-0 / 1-2 / / 3 empty 1 through 1 empty 1 through 3 empty;

[0105] Comb GB3: 0-1 / 1-0 / / Full wear;

[0106] Comb GB4: 3-3 / 0-0 / / Full wear;

[0107] raw material:

[0108] Comb GB1: 32S / 5 paper yarn strands

[0109] Combing bar GB2: 40S / 4 vortex spun cotton yarn

[0110] Comb bar GB3: 50D / 36f semi-dull polyester DTY

[0111] Comb GB4: 75D / 36f semi-dull polyester DTY.

[0112] Input the organization of the yarn padding number, warp feed amount, and draft density into the computer display screen of the control cabinet, save it, load the machine file, and start the machine; after weaving, the raw fabric is obtained, weighed, bagged, and put into storage.

[0113] Step 4, finishing: dyeing, setting, etc.

[0114] Step 5: Testing and packaging.

[0115] Through the above processes, a warp-knitted cable knit fabric with a simulated flat knitting pattern, as described in this embodiment, is obtained. The cotton yarn, with its excellent moisture absorption, and the polyester yarn, with its poor moisture absorption, create a wetting gradient due to their different hydrophilic and hydrophobic properties. This allows moisture to be quickly transferred from the front to the back of the fabric, achieving the effect of moisture absorption and wicking away sweat. Furthermore, the addition of paper yarn enriches the fabric's pattern and makes it more visually appealing. This warp-knitted cable knit fabric with a simulated flat knitting pattern can be used for summer short-sleeved shirts.

[0116] Example 4:

[0117] A warp-knitted fabric with a cable knit structure, comprising the following percentages by weight: 4.89% 32S / 5 cashmere wool core-spun yarn, 11.46% 40S / 4 cashmere wool core-spun yarn, 20.57% 8.3tex cotton single yarn, and 63.09% 160D / 36f semi-dull polyester.

[0118] The production process of this fabric is as follows: The specific flow of each process is as follows: including selection and matching of the guide bar structure, preparation, warping, weaving, and finishing. The specific steps of the fabric production process are as follows:

[0119] Step 1, Material Selection: Use 32S / 5 cashmere wool core-spun yarn, 40S / 4 cashmere wool core-spun yarn, 8.3tex cotton single yarn, and 160D / 36f semi-dull polyester as raw materials;

[0120] Step 2, Warping: Based on a width of 150cm, a horizontal density of 5.0wpc, the warp threading of GB1 combs is 8 gaps and 1 thread, the warp threading of GB2 combs is 3 gaps, 1 thread, 1 gap, 1 thread, and 3 gaps, and the warp threading of GB3 and GB4 combs is full threading; the calculated warp threading head count is 28 for GB1 combs, 56 for GB2 combs, and 250 for GB3 and GB4 combs.

[0121] The temperature at the warping site is 25±1℃ and the relative humidity is 65±5%. The relatively high and stable temperature and humidity help stabilize the twist of the polyester yarn and make the surface soft, preventing the yarn from getting tangled and which is beneficial to the production of warp-knitted products.

[0122] Step 3, Weaving: Weaving is carried out using a single-needle bed Raschel warp knitting machine with a pressure plate;

[0123] Model: Raschel warp knitting machine RS4 / 2F

[0124] Model number: 12 pins

[0125] Width: 130 inches

[0126] Warp knitting structure and yarn threading method:

[0127] Comb GB1: 1-0 / 1-1 / 1-2 / 1-1 / / 8 gaps 1 pass-through;

[0128] Comb GB2: 1-0 / 2-3 / 1-0 / 1-2 / / 3 empty 1 through 1 empty 1 through 3 empty;

[0136] Input the weaving pattern, warp feed amount, and draft density into the computer display screen of the control cabinet, save the data, load the machine file, and then start the machine. After weaving, the raw fabric is obtained, weighed, bagged, and stored in the warehouse.

[0137] Step 4, finishing: dyeing, setting, etc.

[0138] Step 5: Testing and packaging.

[0139] Through the above processes, a warp-knitted cable knit fabric with a simulated flat knit structure, as described in this embodiment, can be obtained. The pressed yarn structure, woven from paper yarn and cashmere / wool blended yarns, floats on the reverse side of the fabric. The combination of paper yarn and cashmere / wool yarns gives the fabric a unique feel and appearance. The base fabric, formed by polyester and cotton yarns, combines wearing comfort and stability. This warp-knitted cable knit fabric with a simulated flat knit structure can be used for outerwear, cardigans, and other garments.

[0140] Because flat knitting machines typically feed single yarns into needles to form loops sequentially, their production speed is relatively low, and the width of the knitted fabric is limited, resulting in a small output. This makes it difficult to meet the demand for larger production volumes when needed urgently. This invention utilizes a high-speed warp knitting machine for production. The warp knitting machine's width and speed are far superior to those of a computerized flat knitting machine, enabling it to meet the demands of large orders and high production volumes.

[0141] Because flat knitting machines require specialized needles with an elastic expander during cable knitting, the yarn is inevitably damaged during transfer. When the transfer stitches are large or continuous, the tension on each loop is uneven, concentrating on the taut loops, making the yarn prone to breakage and causing holes in the fabric surface. Furthermore, the presence of eyelets, loop protrusions, and twisting at the transfer points affect the fabric's strength, abrasion resistance, pilling, and snagging properties. This invention employs a pressed-yarn warp knitting structure, where the yarn is not woven into loops but rather loops at the base of the ground knitting loops at the beginning and end of the padding motion. This minimizes yarn damage, and the ground knitting uses weft insertion and chain stitching, resulting in fabric with good dimensional stability, high strength, and resistance to unraveling.

[0142] Because the cable knit structure creates holes, unevenness, coil tilting, or twisting effects through the transfer needle arc knitting process, it not only damages the mechanical properties of the yarn but also results in low yield. To mimic the pattern effect of a flat knitting machine's cable knit structure, this invention uses a four-comb Raschel warp knitting machine to knit warp-knitted fabrics with a pressing structure. The effect of mimicking a flat knitting machine's cable knit structure is achieved by changing the padding yarn number, yarn threading cycle, and the shape of the open and closed coils.

[0143] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
