Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to a warp-knitted shoe material fabric with gold and silver yarn. Background Technology

[0002] In modern footwear manufacturing, warp-knitted shoe materials, as a high-performance and multifunctional fabric type, are gradually becoming the preferred material for footwear designers and manufacturers. Warp-knitted shoe materials are fabrics obtained by weaving yarns into a specific structure using warp knitting technology. This type of fabric not only possesses the comfort and durability of traditional shoe materials, but also exhibits superior performance in terms of elasticity, breathability, stability, and aesthetic appearance.

[0003] Chinese Patent Application No. 202023335340.X discloses a breathable warp-knitted fabric for shoes, comprising a woven layer made of interwoven yarns. The yarns have interlocking grooves pressed into the yarns, and a sweat-absorbing layer is integrally woven into the bottom surface of the woven layer. This invention, by pressing the grooves into the yarns and weaving them into a woven layer, creates interconnected ventilation channels. Shoes made from this fabric exhibit improved breathability, effectively wicking away odors from foot sweat, while also utilizing the sweat-absorbing layer. However, this warp-knitted fabric cannot simultaneously achieve a beautiful iridescent sheen and jacquard effect.

[0004] Chinese patent application number 202122796014.7 discloses a chameleon-patterned shoe fabric, which is woven from warp and weft yarns. The ground warp is made of transparent TPU monofilament, and the skein warp is made of transparent nylon monofilament. The first weft yarn is transparent nylon monofilament, the second weft yarn is fluorescent green polyester double-twisted yarn, the third weft yarn is black polyester double-twisted yarn, and the fourth weft yarn is purple or carnation red polyester double-twisted yarn. The weft yarns are arranged in the following order: two first weft yarns, one second weft yarn, three third weft yarns, and one fourth weft yarn. The ground warp yarn is woven with the first weft yarn in a plain weave, with the second weft yarn in a five-end weft satin weave, with the third weft yarn in a ten-end weft satin weave, and with the fourth weft yarn in a five-end weave. The use of transparent TPU and nylon monofilaments in the warp yarns does not visually affect the continuity of the weft yarn colors. By selecting and matching the weft yarn colors, a shoe fabric with multiple colors and a color-changing effect when viewed from different angles is formed. However, the fabric's sheen and jacquard effect lack depth. Utility Model Content

[0005] Therefore, in view of the above problems, this utility model provides a warp-knitted shoe material fabric with gold and silver yarns, which solves the problem that existing warp-knitted shoe material fabrics cannot have both exquisite seven-color luster and jacquard effect, and that the fabric surface luster and jacquard effect do not have a sense of layering.

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

[0007] A warp-knitted shoe material fabric with gold and silver yarns includes a fabric body, which is woven from six combs: GB1, JB2.1, JB2.2, GB3, GB4, and GB5. The JB2.1 and JB2.2 combs are preceded by a GB1 ground comb, and the JB2.1 and JB2.2 combs are followed by three GB3, GB4, and GB5 ground combs.

[0008] Wherein, A: first raw material, B: second raw material, C: third raw material, *: void;

[0009] The organizational structure of GB1 is 0-0-0-1 / 1-1-1-0 / / 1A;

[0010] The organizational structure of JB2.1 is 0-0-0-0 / 2-2-2-2 / / 1B;

[0011] The organizational structure of JB2.2 is 0-0-0-0 / 2-2-2-2 / / 1B;

[0012] The organizational structure of GB3 is 0-0 / 3-3 / / 1C,1*;

[0013] The organizational structure of GB4 is 2-2-0-1 / 1-1-3-2 / / 1A;

[0014] The organizational structure of GB5 is 2-2-0-1 / 1-1-3-2 / / 1A;

[0015] Quantity of menstrual blood delivered:

[0016] GB1: 4mm / row;

[0017] JB2.1: 1.7mm / three large and three small columns in each row;

[0018] JB2.2: 1.7mm / three large and three small columns in each row;

[0019] GB3: 1.7mm / row;

[0020] GB4: 4.5mm / row;

[0021] GB5: 4.5mm / row.

[0022] In the textile industry, the warp feed rate is an important process parameter, referring to the length of warp yarn required to be fed out for each certain number of loop rows during warp knitting. This parameter is usually expressed in "run inperrack," which is defined as the length of warp yarn (in millimeters) required to be fed out for every 480 loop rows. For example, "4mm / run inperrack" means that the warp feed rate required to knit one loop is 4mm, or it can be expressed as 4mm * 480 runs = 1920mm / run inperrack.

[0023] During warp feeding, there are six tension plates on the yarn frame to control the tension: three large tension plates and three small tension plates. The yarn tension is controlled by whether the tension plates are pressed down; pressing down increases the tension. For example, "two large and three small" means pressing down two of the large tension plates and three of the small tension plates. In this application, "three large and three small" refers to pressing down three large tension plates and three of the small tension plates.

[0024] Furthermore, the fabric body has a warp density of 10 wpc, a weft density of 15 cpc, a tensile density of 14.5 cpc, and a weight of 293 g / m². 2 .

[0025] Furthermore, A: 0.10mm polyester fold-resistant yarn, B: polyester DTY200D / 96F heavy-duty untwisted yarn, and C: polyester iridescent yarn MX-12, wherein the polyester iridescent yarn MX-12 is made by twisting one polyester film slice and two polyester monofilaments together.

[0026] Furthermore, the third raw material is fully spread below the first raw material.

[0027] Furthermore, the GB3 yarn threading method is one thread through and one open, with a weft-inserted weft structure.

[0028] Furthermore, GB4 and GB5 are woven into a circular structure to form a transparent and translucent plain front.

[0029] Furthermore, the GB1 braided chain structure.

[0030] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows:

[0031] The polyester iridescent yarn MX-12 is a type of gold and silver yarn, which is made by twisting a polyester film slice and two polyester monofilaments. The polyester film slice is precisely cut to give the yarn a laser silver luster, while the polyester monofilaments are used to enhance the yarn strength and weaveability without interfering with the luster of the iridescent yarn MX-12.

[0032] By combining the characteristics of two raw materials, polyester iridescent yarn MX-12 and polyester fold-resistant yarn, the polyester iridescent yarn is fully laid under the polyester fold-resistant yarn. The polyester fold-resistant yarn is transparent and has high strength, which can maximize the preservation of the luster of the polyester iridescent yarn. This also makes the shoe material not only lightweight and breathable, but also has excellent wear resistance and fold resistance.

[0033] After the weft guide bar, there are two ground guide bars, GB4 and GB5, woven with polyester fold-resistant yarn into a loop structure, forming a transparent and clear plain weave front. This not only makes the fabric wear-resistant and fold-resistant but also clearly showcases the jacquard effect and iridescent luster. Polyester iridescent yarn has poorer evenness and a slightly stiffer feel than ordinary yarn. Therefore, after the jacquard guide bar, GB3, it is threaded into the ground guide bar with one pass and one gap, and woven with a weft guide structure. This not only ensures sufficient iridescent luster but also guarantees normal fabric weaving and stable machine operation.

[0034] The fabric used in this application is manufactured on a single jacquard warp knitting machine. The jacquard guide bar employs a passive yarn feeding method, allowing each jacquard warp yarn to be free from tension limitations, enabling the creation of jacquard patterns with varying densities, resulting in a rich variety of diverse jacquard textures. When the jacquard is woven into a loop structure, the loops obscure the iridescent yarns, resulting in a matte fabric surface. When the weft-inserted structure is woven, the iridescent yarns' sheen is combined with the jacquard's shadow effect, enhancing the fabric's luster and jacquard texture. The weft-inserted structure formed by the iridescent yarns and the jacquard weft-inserted structure are formed by a ground guide bar (GB1) in front of the jacquard guide bar, which uses polyester fold-resistant yarn to weave a chain structure to prevent the yarns from slipping out of the fabric.

[0041] The embodiment of this utility model is as follows:

[0042] refer to Figures 1 to 5 A warp-knitted shoe material fabric with gold and silver yarns includes a fabric body, which is woven from six combs: GB1, JB2.1, JB2.2, GB3, GB4, and GB5. The JB2.1 and JB2.2 combs are preceded by a GB1 ground comb, and the JB2.1 and JB2.2 combs are followed by three GB3, GB4, and GB5 ground combs.

[0043] Wherein, A: first raw material, B: second raw material, C: third raw material, *: void;

[0044] The organizational structure of GB1 is 0-0-0-1 / 1-1-1-0 / / 1A;

[0045] The organizational structure of JB2.1 is 0-0-0-0 / 2-2-2-2 / / 1B;

[0048] The organizational structure of GB4 is 2-2-0-1 / 1-1-3-2 / / 1A;

[0049] The organizational structure of GB5 is 2-2-0-1 / 1-1-3-2 / / 1A;

[0050] Quantity of menstrual blood delivered:

[0051] GB1: 4mm / row;

[0052] JB2.1: 1.7mm / three large and three small columns in each row;

[0053] JB2.2: 1.7mm / three large and three small columns in each row;

[0054] GB3: 1.7mm / row;

[0055] GB4: 4.5mm / row;

[0056] GB5: 4.5mm / row;

[0057] The fabric body has a warp density of 10 wpc, a weft density of 15 cpc, a tensile density of 14.5 cpc, and a weight of 293 g / m². 2A: 0.10mm polyester fold-resistant yarn, which is composed of abrasion-resistant PBT masterbatch and bright PET chips. It not only has the abrasion and fold resistance of PBT, but also the high strength and high modulus of PET, and presents a transparent and transparent appearance; B: polyester DTY200D / 96F heavy-net untwisted yarn, which has high fiber breaking strength and elastic modulus, moderate resilience, and excellent heat setting performance; C: polyester iridescent yarn MX-12, which is a type of gold and silver yarn, made by twisting one polyester film chip and two polyester monofilaments. The polyester film chip is precisely cut to give the yarn a laser silver luster, and the polyester monofilaments are used to enhance the yarn strength and weaveability without interfering with the iridescent luster; the third raw material is fully laid under the first raw material. The threading method of GB3 is one thread and one gap, and the weft weave is woven. GB4 and GB5 are woven into a loop structure to form a transparent and transparent plain weave front. GB1 is woven into a chain weave.

[0058] Because the uniformity of the MX-12 rainbow yarn is inferior to that of ordinary yarn and its hand feel is slightly stiffer, the ground comb after the jacquard comb, namely GB3, is threaded into the MX-12 rainbow yarn using a one-through-one-open-through method to weave a weft-insertion structure. After the weft-insertion ground comb, there are two ground combs, GB4 and GB5, which are woven into a loop structure using polyester fold-resistant yarn, forming a transparent and translucent plain weave front. This not only provides wear and fold resistance but also clearly showcases the jacquard effect and rainbow sheen. The jacquard comb uses a passive warp feed method provided by the yarn frame. All warp yarns on this warp beam do not affect each other, making it easier to design different process structures and adjust the corresponding warp feed amount for different styles in different areas. When the jacquard is woven into a loop structure, the loops cover the rainbow yarn, resulting in a matte fabric surface. When weaving a weft-insertion structure, the fabric surface displays the rainbow yarn sheen while also exhibiting the shadow effect of the jacquard, making the fabric sheen and jacquard effect more layered. The weft-lining structure formed by the colorful yarn weaving and the Jacquard weft-lining structure are formed by a ground comb in front of the Jacquard comb, namely GB1, which is woven with polyester fold-resistant yarn to prevent the yarn from floating out of the fabric.

[0059] Post-processing design

[0060] (1) Pre-designed process

[0061] Pre-setting is one of the most important processes in the finishing stage, and the pre-setting machine used is the EAG-2000-CBR-0 Taiwan Ligen pre-setting machine. This machine uses high-temperature hot air setting technology, which allows hot air to act evenly on both sides of the fabric. When the temperature inside the closed oven of the pre-setting machine is higher than the glass transition temperature of the fabric, the polymers inside the fiber raw material undergo reorganization, thereby changing the surface dimensions of the fabric. The greige fabric is fed into the pre-setting machine along the reverse weave direction. First, the fabric is stretched or contracted to its setting dimensions by the overfeed roller device and the pin chain stretching device. It then undergoes setting treatment in multiple dry, hot, and sealed oven devices. After setting, the fabric is cooled to complete the pre-setting process. The fabric is a single-layer fabric, so the setting speed is slightly faster. The pre-setting temperature is set at 200℃, and the fabric input speed is set at 25 yards / min.

[0062] (2) Dyeing process

[0063] The fabric is dyed using a high-temperature, high-pressure overflow dyeing method. Disperse dyes are used to dye the polyester; disperse red ACE and disperse yellow ACE give the polyester a warm white color. The dyeing machine is a HAS-1-5 Donggeng high-temperature, high-pressure overflow dyeing machine. Specific dye and auxiliary agent formulations are shown in Table 1.

[0064] Table 1

[0065] Dye Name content Dispersed Red ACE 0.0002％ Dispersible yellow ACE 0.0003％ High-temperature leveling agent DM-2115A 0.5g / L Buffer acid NX-306 0.2g / L Citric acid 0.0002g / L

[0066] Specifically, such as Figure 5 As shown, the auxiliary agent is first added at room temperature, and the temperature needs to be increased stepwise. The temperature is first increased to 120℃ at a rate of 2℃ / min and maintained for 30 minutes for dyeing treatment. Then, the temperature is decreased to 80℃ at a rate of 2.5℃ / min for sampling and color matching. After washing and draining, the fabric is finally washed with room temperature water for 10 minutes at a time and drained.

[0067] (3) Tensioning and setting process

[0068] The principle of tenter frame setting is basically the same as that of pre-setting. The most important difference is the setting temperature and setting time. The EAG-2300-CBR-0 Taiwan Ligen tenter frame setting machine is used. The tenter frame setting temperature is set at 180℃ and the input fabric speed is set at 20 yards / min.

[0069] The warp-knitted shoe material fabric with gold and silver yarn prepared by this technical solution has been tested by the Fujian Provincial Fiber Testing Center. The fabric has fully met the requirements of the Fujian Provincial Fiber Testing Center and the customer. Details of the specific indicators are shown in Table 2.

[0070] Table 2

[0071]

[0072]

[0073] As shown in Table 2, the fabric's phenolic yellowing and light fastness both reach level 4 or above, indicating good storage and lightfastness. The fabric's pH is 5.6, and no formaldehyde was detected, meeting the fabric's performance requirements. The fabric's bursting strength reaches 1.77 × 10⁻⁶. 3 The high kPa and tear strength indicate that even a single-layer fabric has excellent strength. The fabric's abrasion resistance reaches level 4, and its folding resistance remains intact at both room and low temperatures, demonstrating excellent abrasion and folding resistance. All the fabric's testing indicators meet the requirements for footwear materials and uppers.

[0074] 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.
