Description

Technical Field

[0001] This utility model relates to the textile field, specifically to a multi-layered plush warp-knitted shoe material fabric. Background Technology

[0002] Warp-knitted fabrics are now an important material for shoe upper production. As shoe uppers, they offer advantages such as fine texture, lightweight material, softness and comfort, and breathable mesh. The structure of warp-knitted shoe uppers has evolved from early single and double-layer jacquard to three-layer mesh jacquard, and now to partial napping and textured surfaces, demanding greater variety in styles and a more layered, three-dimensional feel. Traditional plush warp-knitted products, as shown in the technical solution of Chinese Patent Publication No. CN 101173416A, are made by weaving polyester porous ultra-fine denier filaments on a warp knitting machine, followed by pretreatment, heat setting before dyeing, wet treatment, napping after dyeing, calendering, and shearing. The raw material used in the weaving process is 150D / 288F polyester.

[0003] This technical solution is an improvement upon the previous one, in order to obtain a more suitable warp-knitted upper based on the characteristics of the shoe upper. Utility Model Content

[0004] Therefore, this utility model provides a multi-layer plush warp-knitted shoe material fabric, which solves the problem of insufficient adaptability of current warp-knitted fabrics to shoe upper products.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A multi-layer plush warp-knitted shoe material fabric includes a fabric body, which is warp-knitted from four raw materials A, B, C and D, and is woven from six comb bars of GB1, JB2.1, JB2.2, JB3.1, JB3.2 and GB4.

[0007] A and C are both polyester; B is cationic polyester untwisted yarn; D is polyester fold-resistant yarn.

[0008] The fabric body's manufacturing process is as follows:

[0009] GB1: 1-1-1-0 / 0-0-0-1 / / 1A;

[0010] JB2.1:1-0-0-1 / 1-2-2-1 / / 1B;

[0011] JB2.2:1-0-0-1 / 1-2-2-1 / / 1B;

[0012] JB3.1:1-0-0-1 / 1-2-2-1 / / 1C;

[0013] JB3.2:1-0-0-1 / 1-2-2-1 / / 1C;

[0014] GB4: 1-0 / 0-1 / / 1D;

[0015] The amount of medicine delivered is:

[0016] GB1: 3.9mm / row;

[0017] JB2.1: 6mm / row;

[0018] JB2.2: 6mm / row;

[0019] JB3.1: 6mm / row;

[0020] JB3.2: 6mm / row;

[0021] GB4: 4.1mm / row.

[0022] Preferably, B uses cationic bright light mesh untwisted yarn; C uses polyester light mesh untwisted yarn.

[0023] Preferably, the fabric body has a warp density of 8-12 wpc, a weft density of 10-15 cpc, a tensile density of 10-20 cpc, and a weight of 200-600 g / m². 2 .

[0024] Preferably, the fabric body has a warp density of 10 wpc, a weft density of 13 cpc, a tensile density of 12.3 cpc, and a basis weight of 411 g / m². 2 .

[0025] Preferably, A is polyester FDY150D / 48F; B is cationic bright DTY150D / 144F light mesh untwisted yarn; C is polyester DTY150D / 144F light mesh untwisted yarn; and D is 0.10 polyester fold-resistant yarn.

[0026] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0027] This technical solution uses polyester and cationic polyester untwisted yarn as the main raw materials, which can form a two-color effect and enrich the fabric color. At the same time, it is combined with polyester fold-resistant yarn, which is high-strength, fold-resistant and transparent, and can preserve the original color of the fabric to the maximum extent.

[0028] In production, warp knitting machines use guide bars for weaving, with a jacquard guide bar at both the front and back. The jacquard guide bar can freely form loops on the front and back needle beds. If two needles are connected on each bed, a high pile is formed; if two needles on the front bed form a loop and one needle on the back bed, a medium pile is formed; if one needle is connected on each bed, a low pile is formed; if loops are formed only on the back bed, there is no pile. Furthermore, breathable mesh of varying sizes and lengths can be formed in any area. Therefore, the fabric can achieve a two-tone, multi-layered pile effect and breathable openings in non-pile areas. Thus, the pile length and the presence or absence of mesh can be freely designed according to the performance requirements of different shoe parts, allowing the fabric to combine warmth and breathability for a more suitable shoe material for this product category. Attached Figure Description

[0029] Figure 1 This is a schematic diagram of the fabric raw material process structure of an embodiment of this utility model. Detailed Implementation

[0030] The following will describe the implementation of this utility model in detail with reference to specific embodiments, so that the process of how this utility model uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0031] Example

[0032] refer to Figure 1 A multi-layer plush warp-knitted shoe material fabric includes a fabric body, which is warp-knitted from four raw materials A, B, C and D, and is woven from six comb bars of GB1, JB2.1, JB2.2, JB3.1, JB3.2 and GB4.

[0033] A and C are both polyester; B is cationic polyester untwisted yarn; D is polyester fold-resistant yarn.

[0034] The fabric body's manufacturing process is as follows:

[0035] GB1: 1-1-1-0 / 0-0-0-1 / / 1A;

[0036] JB2.1:1-0-0-1 / 1-2-2-1 / / 1B;

[0037] JB2.2:1-0-0-1 / 1-2-2-1 / / 1B;

[0038] JB3.1:1-0-0-1 / 1-2-2-1 / / 1C;

[0039] JB3.2:1-0-0-1 / 1-2-2-1 / / 1C;

[0040] GB4: 1-0 / 0-1 / / 1D;

[0041] The amount of medicine delivered is:

[0042] GB1: 3.9mm / row;

[0043] JB2.1: 6mm / row;

[0044] JB2.2: 6mm / row;

[0045] JB3.1: 6mm / row;

[0046] JB3.2: 6mm / row;

[0047] GB4: 4.1mm / row.

[0048] As shown above, the fabric body is woven with six combs, including a Jacquard comb (JB) and a ground comb (GB) at the front and back. The Jacquard comb can freely form loops on the front and back needle beds. If two stitches are connected on each of the front and back needle beds, a high pile can be formed; if two stitches are connected on the front needle bed and one stitch is connected on the back needle bed, a medium pile can be formed; if one stitch is connected on each of the front and back needle beds, a low pile can be formed; if loops are only formed on the back needle bed, there is no pile. Furthermore, breathable meshes of varying sizes and lengths can be formed in any area. Therefore, the fabric can form a two-color, multi-layered pile effect and breathable openings in areas without pile. Thus, the pile length and the presence or absence of meshes can be freely designed according to the performance requirements of different parts of the shoe, so that the fabric has both warmth and breathability, making it a more suitable shoe material for this type of product.

[0049] In production, the RDPJ4 / 2 type double Jacquard warp knitting machine is selected, equipped with headless needles. The Jacquard comb uses a passive warp feed mechanism with a yarn frame, which passively feeds the yarn according to the weave process. The tension between the warp yarns is independently controlled and does not affect each other. This can not only meet the large warp feed requirements of long-pile plush but also the small warp feed requirements of non-pile plush.

[0050] This technical solution uses polyester and cationic polyester untwisted yarn as the main raw materials, which can form a two-color effect and enrich the fabric color. At the same time, it is combined with polyester fold-resistant yarn, which is high-strength, fold-resistant and transparent, and can preserve the original color of the fabric to the maximum extent.

[0051] In this embodiment, B is selected as cationic bright lightweight untwisted yarn; C is selected as polyester lightweight untwisted yarn. The parameters of the fabric body are: warp density 10wpc, weft density 13cpc, stretch density 12.3cpc, and weight 411g / m². 2 .

[0052] The specific models of the four raw materials A, B, C, and D are as follows: A is polyester FDY150D / 48F; B is cationic bright DTY150D / 144F light mesh untwisted yarn; C is polyester DTY150D / 144F light mesh untwisted yarn; and D is 0.10 polyester fold-resistant yarn. The 150D / 144F yarn is chosen for its fineness and high F number (F number in polyester refers to the number of individual fibers in a single yarn, i.e., the number of individual fibers contained in a single warp or weft yarn). Therefore, the yarn is fluffy and soft, creating a delicate and dense plush effect. Both are untwisted yarns, so when used on a yarn frame, they will not cause twisting, knotting, or clogging of the needles.

[0053] In terms of manufacturing process, the finished fabric, after pre-setting, dyeing, and stretching, has undergone meticulous testing by the Fujian Provincial Fiber Testing Center. The fabric has fully met the requirements of both the Fujian Provincial Fiber Testing Center and the client. Details of the specific indicators are as follows:

[0054]

[0055]

[0056]

[0057]

[0058] As shown in the table, the fabric exhibits excellent colorfastness (4-5 or higher) in terms of resistance to dry and wet rubbing, sweat, and soap washing. Its bursting strength reaches 1.47 × 10³ kPa, indicating high tear strength and overall excellent strength. The fabric also demonstrates excellent abrasion resistance (4 levels) and good folding resistance at both room and low temperatures, indicating superior abrasion and folding resistance. All test indicators meet the requirements for shoe upper materials, thus the fabric quality meets the predetermined design requirements of this project.

[0059] Accordingly, depending on the specific models of the four raw materials A, B, C, and D, the parameters of the fabric body are as follows: warp density 8-12 wpc, weft density 10-15 cpc, tensile density 10-20 cpc, and weight 200-600 g / m². 2 Within the range.

[0060] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
