TECHNICAL FIELD

[0001] The present application relates to the technical field of fabric, in particular to a preparation process of a yarn rack jacquard material with hot melt yarn. BACKGROUND

[0002] At present, people pay more and more attention to health and sports, and the market demand for sports shoes also increases significantly. The production process of traditional sports shoes has many steps. Some existing shoe fabrics use warp-knitted jacquard spacer mechanisms, and the upper and lower fabrics and the middle spacer layer. However, the existing warp-knitted jacquard fabric has low bursting performance and wear resistance, and therefore there is an urgent need for a jacquard fabric with good durability. SUMMARY

[0003] Therefore, in view of the above problems, the present application provides a preparation process of a yarn rack jacquard material with hot melt yarn, which solves the technical problem of low bursting performance and wear resistance of the existing warp-knitted jacquard fabric.

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0025] refer to Figs. 1 to 3 This embodiment provides a process for preparing a jacquard material with a heat-melting yarn frame, including the following steps:

[0026] (1) Machine parameters: Model RDJ6 / 2, machine working width 350.5 (138 inches), machine speed 380 r / min;

[0027] (2) Six combs are used for weaving, including three ground combs (GB1, GB2 and GB6), one spacer comb (GB3), and two Jacquard combs (JB4 and JB5). Jacquard comb JB5 and ground comb GB6 use 222dtex / 144 polyester filaments with a warp feed of 1750mm / rack. Ground combs GB1, GB2 and JB4 use 167dtex / 72 cationic dyeable polyester filaments with a warp feed of 2900mm / rack. Spacer comb GB3 uses 33.3dtex polyester monofilaments with a warp feed of 7460mm / rack. The spacing between the release plates is 2.8 to 3.1mm.

[0028] GB1: 0-1-1-1 / 1-0-0-0 / / ;

[0029] GB2: 2-3-1-1 / 1-0-1-1 / / ;

[0030] GB3: 1-0-2-1 / 2-3-1-2 / / ;

[0031] JB4: 1-0-1-1 / 1-2-1-1 / / ;

[0032] JB5: 1-1-1-2 / 1-1-1-0 / / ;

[0033] GB6: 0-0-0-1 / 1-1-1-0 / / ;

[0034] (3) Finishing: including washing, fabric setting, dyeing and resetting to produce the finished fabric.

[0035] GB1 and GB2 can weave the upper layer of the shoe material on the front needle bed, while GB6 works in conjunction with JB4 and JB5 to weave the lower layer of the material on the back needle bed. The spacer comb GB3 creates the middle spacer layer of the shoe material by alternating loops on the front and back needle beds, thus connecting and supporting the upper and lower layers of the fabric.

[0036] According to GB / T3903.16—2008, the average number of abrasion cycles for dry rubbing and wet rubbing is greater than 3500 and 16500 respectively. According to GB / T19976—2005, the average bursting strength is greater than 500N. After weaving, the fabric has good abrasion resistance and is not easily torn during use.

[0037] The reshaped output fabric is then cut and divided into squares. After completion, it is conveyed by conveyor belt (1). When passing under the transfer device, a waterproof and breathable membrane and mesh fabric are placed on the cut jacquard material.

[0038] The transfer device includes a conveyor belt 1, a frame 2 located on one side of the conveyor belt 1, a first adsorption roller 3 rotatably located on the top of one side of the frame 2, a transfer station 4 located below the first adsorption roller 3, a transfer plate 5 rotatably located on the frame 2 for transferring material from the first adsorption roller 3 to the conveyor belt 1, and a drive device 6 for driving the transfer plate 5 and the first adsorption roller 3 to rotate. The frame 2 is located above the first adsorption roller 3 and a second adsorption roller 7 is rotatably provided. The first adsorption roller 3 and the second adsorption roller 7 are existing technologies and will not be described in detail here.

[0039] During use, the disassembled and cut jacquard material is conveyed to the transfer device via a transmission belt. The first adsorption roller 3 adsorbs the waterproof and breathable membrane input at the transfer station 4 below. After completion, the drive device 6 drives the first adsorption roller 3 to rotate. When passing under the second adsorption roller 7, the mesh fabric is transferred to the top of the first adsorption roller 3. After completion, the drive device 6 drives the transfer plate 5 to transfer the waterproof and breathable membrane and mesh fabric from the surface of the adsorption roller to the top surface of the conveyor belt 1. The transfer of the waterproof and breathable membrane and mesh fabric can be completed automatically without manual stacking of the jacquard material, thus improving production speed. This fabric avoids the disadvantage of poor waterproof performance caused by the breathability of jacquard material.

[0040] A first gear 8 is provided on one side of the first adsorption roller 3, a second gear 9 is provided on one side of the second adsorption roller 7, and a transmission gear 10 is provided between the first gear 8 and the second gear 9.

[0041] The driving device 6 includes an intermittent wheel 601 located on one side of the first adsorption roller 3, multiple arc-shaped openings 602 located outside the intermittent wheel 601, U-shaped openings 603 located between the arc-shaped openings 602, a driving wheel 604 rotatably mounted on the frame 2 and located below the intermittent wheel 601, a semi-circular ring 605 located outside the driving wheel and in contact with the arc-shaped openings 602, a lever 606 fixed on one side of the driving wheel 604 and inserted into the U-shaped opening 603, a first connecting rod 607 located on the side of the driving wheel 604 away from the lever 606, a transmission shaft 608 rotatably mounted on the frame 2, and a first connecting rod 607 located on one side of the transmission shaft 608. The system includes a second connecting rod 609, a third connecting rod 610 located between the first connecting rod 607 and the second connecting rod 609, a fourth connecting rod 611 located outside the drive shaft 608, a rectangular block 612 rotatably mounted on the frame 2 and located to the upper left of the drive shaft 608, a rectangular hole 614 vertically mounted on the transfer plate 5 and slidably connected to the rectangular block 612, and a motor 613 for driving the drive shaft 608 to rotate. The fourth connecting rod 611 is rotatably connected to the transfer plate 5 on the side away from the drive shaft 608. The first adsorption roller 3 is polygonal in shape, preferably octagonal, and the U-shaped opening 603 preferably has eight openings.

[0042] After the conveyor belt 1 moves the disassembled and cut jacquard material to below the transfer device, it stops running. The motor 613 drives the drive shaft 608 to rotate, which in turn drives the fourth link 611 and the second link 609 to rotate. When the second link 609 drives the drive wheel 604 to rotate via the third link 610, the lever 606 of the drive wheel 604 engages with the U-shaped opening 603 on the outside of the intermittent wheel 601, causing the first adsorption roller 3 to rotate 45 degrees. After this, the lever 606 of the drive wheel 604 leaves the intermittent wheel 601, and the semi-circular ring 605 on the outside of the drive wheel 604 fits against the arc-shaped opening 602 of the intermittent wheel 601. As the drive wheel 604 continues to rotate, it will remain fixed, and the fourth link 611 will move towards the first adsorption roller. 3. In the initial debugging state, the waterproof and breathable membrane is placed at the transfer station 4. After the adsorption roller adsorbs and transfers the waterproof and breathable membrane upward, it will be rotated and conveyed. The external transfer device will place the cut and matched mesh fabric outside the second conveyor roller. When the first adsorption rotates, the first gear 8 on one side drives the second gear 9 to rotate through the transmission gear 10. The second gear 9 drives the second conveyor roller to rotate synchronously. After the rotation is completed, the first adsorption roller 3 will adsorb and transfer the mesh fabric that falls from the second conveyor roller to the left side. When the transfer plate 5 moves towards the position of the first adsorption roller 3 through the fourth connecting rod 611, the transfer plate 5 will adsorb the mesh fabric and waterproof and breathable membrane on the first adsorption roller 3. After completion, the transmission belt moves and moves the new yarn frame Jacquard material to the bottom of the transfer device.
