Description

Technical Field

[0001] This invention relates to the textile field, and in particular to a discontinuous jacquard velvet ribbon and its weaving method. Background Technology

[0002] Webbing is a common accessory in clothing. To improve the comfort of wearing webbing, a velvet side is usually provided on the side of the webbing that is closest to the skin, thus forming velvet webbing. With the improvement of living standards and the development of the clothing market, the styles of clothing accessories are now incredibly diverse. Although velvet webbing can be used in many clothing accessories, traditional velvet webbing is usually a single, uniform structure with a monotonous visual effect. As consumers' aesthetic demands continue to rise, traditional velvet webbing is gradually failing to meet their requirements. Therefore, many manufacturers, in order to improve the aesthetics of velvet webbing, will print or emboss on the velvet side to achieve richer visual effects and meet customer needs. However, these processing methods have considerable limitations. On the one hand, they require corresponding equipment, increasing production costs and process complexity; on the other hand, the appearance of this type of webbing deteriorates after washing, and the effect is still unsatisfactory. Summary of the Invention

[0003] Based on this, the purpose of the present invention is to provide a discontinuous jacquard velvet ribbon and its weaving method, which has the advantages of rich ribbon structure, high aesthetic appeal and durability.

[0004] A discontinuous jacquard velvet ribbon includes a ribbon body, the ribbon body including warp yarns arranged in the warp direction and at least one layer of pile yarns, and weft yarns arranged in the weft direction, and is integrally woven from the warp yarns, pile yarns and weft yarns to form pile segments and jacquard segments that are alternately and continuously distributed along the warp direction of the ribbon body.

[0005] The present invention discloses an intermittent jacquard velvet webbing that combines jacquard and plush to improve the aesthetics of the webbing and ensure the durability of the pattern.

[0006] Furthermore, the yarn has two layers. The yarn can be combined in various ways to enhance the aesthetics of the webbing.

[0007] This invention also discloses a method for weaving a discontinuous jacquard velvet ribbon, used to weave the velvet ribbon as described above, the steps of which include:

[0008] S1. Prepare the yarn and layup. The warp yarn is distributed in two layers, and the pile yarn is located between the two layers of warp yarn. The warp yarn is threaded in the heddle frame, and the pile yarn is threaded in the loose heddle wire.

[0009] S2. The warp yarn is pulled by a belt drive source. The pile yarn is matched one-to-one with the pile feeding drive source according to the number of layers. Each layer of pile yarn is pulled by a different pile feeding drive source. The length of each pile segment and jacquard segment is determined according to the design. The pile yarn is pulled by the pile feeding drive source at a second speed or a third speed. The second speed is the conveying speed when the pile yarn does not form pile. The third speed is the conveying speed when the pile yarn forms pile.

[0010] S3. When the yarn changes from not forming fluff to forming fluff, control the yarn feeding drive source corresponding to the yarn in that layer to increase the yarn feeding speed from the second speed to exceed the third speed, then reduce it to the third speed, and maintain the third speed for weaving.

[0011] When the yarn changes from forming pile to not forming pile, the pile feeding drive source corresponding to the yarn in that layer is controlled to reduce the yarn feeding speed from the third speed to below the second speed, then rise back to the second speed and maintain the second speed for weaving;

[0012] S4. Cut the yarn of the pile segment with a cutter.

[0013] When the feeding speed of the yarn is varied, the method can achieve an intermittent transition between the pile section and the jacquard section by exceeding or falling below the target speed, while ensuring the tightness of the jacquard section and the looseness of the pile section, thereby improving the aesthetics of the webbing.

[0014] Furthermore, the belt drive source pulls the warp yarn at a first speed at a constant speed, and the third speed is greater than the first speed. This ensures that the pile of the pile segment has sufficient height.

[0015] Furthermore, the belt pulling drive source and the yarn feeding drive source are servo motors. The servo motor allows for easy speed adjustment, thereby enabling timely adjustment of the yarn feeding speed.

[0016] To better understand and implement this invention, the following detailed description is provided in conjunction with the accompanying drawings. Attached Figure Description

[0024] Example 1

[0025] Please see Figure 1-3 , Figure 1 This is a structural diagram of the velvet webbing described in Example 1; Figure 2 This is a schematic diagram of the weaving process of the velvet ribbon described in Example 1; Figure 3 The image shows the yarn feeding process when the velvet webbing described in Example 1 is woven with pile segments-jaculate segments-pile segments.

[0026] This invention discloses a method for weaving a discontinuous jacquard velvet ribbon, thereby producing a discontinuous jacquard velvet ribbon. The discontinuous jacquard velvet ribbon is woven integrally from warp yarns 2, pile yarns 3, and weft yarns, forming alternately and continuously distributed pile segments 11 and jacquard segments 12 along the warp yarn direction of the ribbon body. The warp yarns 2 can be composed of nylon yarn, elastic yarn, etc., to improve the comfort and elasticity of the ribbon. In this embodiment, two layers of warp yarns 2 and one layer of pile yarn 3 are fed along the warp direction, and the weaving method includes the following steps:

[0027] S1. Prepare the yarn and lay the yarn. The warp yarn 2 is distributed in two layers, and the yarn 3 is located between the two layers of warp yarn 2. The warp yarn 2 is threaded in the heddle frame, and the yarn 3 is threaded in the loose heddle yarn.

[0028] S2. Determine the lengths of each pile segment 11 and jacquard segment 12 according to the design, and determine the first speed, second speed, and third speed. The warp yarn 2 is pulled uniformly at the first speed by the pull belt drive source 4. The pile yarn 3 is pulled at the second speed or the third speed by the pile feeding drive source 5. The second speed is the conveying speed of the pile yarn 3 when weaving the jacquard segment 12, and the third speed is the conveying speed of the pile yarn 3 when weaving the pile segment 11.

[0029] To ensure that the pile of the pile segment 11 has sufficient height, the third speed must be greater than the first speed to ensure that a looser pile structure 3 can be woven in.

[0030] The belt pulling drive source 4 includes a belt pulling roller group and a first servo motor. The down feeding drive source 5 includes a down feeding roller group that pulls the down yarn 3 and a second servo motor that drives the down feeding roller group to rotate. The speed of the first servo motor and the second servo motor is adjusted by a control panel.

[0031] S3. In traditional weaving methods, a noticeable transition zone appears at the junction of the jacquard section 12 and the pile section 11. In this transition zone, the pile height is uneven, which is not the desired discontinuous effect. At the same time, due to the significant structural changes in the webbing in the transition zone, the width of the webbing also varies considerably. Therefore, it is necessary to flexibly adjust the weft feed speed in the transition zone to adjust the width of the webbing and keep the width of the webbing uniform.

[0032] When the weaving process moves from the jacquard section 12 to the pile section 11, the pile feeding drive source 5 is controlled to increase the conveying speed of the yarn 3 from the second speed to exceed the third speed, and then decrease to the third speed, and the pile section 11 is woven at the third speed.

[0033] When the weaving process moves from the pile section 11 to the jacquard section 12, the pile feeding drive source 5 is controlled to reduce the conveying speed of the yarn 3 from the third speed to below the second speed, and then rise back to the second speed and maintain the second speed for weaving the pile section 11.

[0034] S4. The woven ribbon is now a structure in which two ribbons are connected to each other at the pile section 11. That is, the jacquard section 12 of the upper ribbon and the lower ribbon are separated, while the pile section 11 is connected by the pile yarn 3. At this time, the pile yarn 3 of the pile section 11 is cut by the cutter 6, and the upper ribbon and the lower ribbon are separated, thus obtaining two ribbons. The jacquard patterns of the upper ribbon and the lower ribbon are mirror symmetrical.

[0035] The discontinuous jacquard velvet ribbon obtained by this process can be clearly divided into pile section 11 and jacquard section 12. When the jacquard of jacquard section 12 is asymmetrical, the jacquard in the upper layer ribbon and the lower layer ribbon are respectively the forward pattern and the mirrored pattern. At this time, the ribbon with the mirrored pattern is discarded, and only the ribbon with the forward pattern is retained as the final product.

[0036] Example 2

[0037] Please see Figure 4-5 , Figure 4 This is a structural diagram of the velvet webbing described in Example 2; Figure 5 This is a schematic diagram of the weaving process of the velvet ribbon described in Example 2.

[0038] This embodiment is basically the same as Embodiment 1, except that: warp yarns 2 and at least two layers of yarn 3 are conveyed along the warp direction, each layer of yarn 3 having different physical parameters, such as color, elasticity, thickness, and hardness. Each layer of yarn 3 is pulled by a separate drive source, thereby allowing independent control and adjustment of the speed of different layers of yarn 3.

[0039] Taking two layers of yarn 3 of different colors as an example, this embodiment is described, divided into a first yarn 31 and a second yarn 32. The discontinuous jacquard velvet ribbon is woven integrally from warp yarns 2, the first yarn 31, the second yarn 32, and weft yarns, forming alternating and continuous pile segments 11 and jacquard segments 12 along the warp direction of the ribbon body. The pile segments 11 include multiple color areas composed of one or more combinations of yarns 3. Since there are only two types of yarns 3 in this embodiment, three color areas can be formed, namely, a first color area 111 where only the first yarn 31 is piled, a second color area 112 where only the second yarn 32 is piled, and a third color area 113 composed of a combination of the first yarn 31 and the second yarn 32.

[0040] S1. Prepare the yarn and lay it out. The warp yarns 2 are distributed in two layers, with the first yarn 31 and the second yarn 32 located between the two layers of warp yarns 2 and spaced apart from each other. The warp yarns 2 are threaded through the heddle frame, and the first yarn 31 and the second yarn 32 are threaded through the loose heddle yarns.

[0041] S2. Determine the length of each pile segment 11 and jacquard segment 12 according to the design, determine the length of each color zone, and determine the first speed, second speed, third speed, fourth speed, or fifth speed.

[0042] The warp yarn 2 is pulled at a constant speed by the pull belt drive source 4 at a first speed. The first pile yarn 31 is pulled at a second speed or a third speed by the first pile feeding drive source 51, and the second pile yarn 32 is pulled at a fourth speed or a fifth speed by the second pile feeding drive source 52. The second and fourth speeds are the conveying speeds of the pile yarn 3 when the jacquard section 12 is being knitted, and the third and fifth speeds are the conveying speeds of the pile yarn 3 when pile needs to be formed. To ensure that the pile of the pile section 11 has sufficient height, both the third and fifth speeds must be greater than the first speed to ensure the knitting height of the pile yarn 3.

[0043] The belt pulling drive source 4 includes a belt pulling roller group and a first servo motor. The first down feeding drive source 51 includes a first down feeding roller group that pulls the first down yarn 31 and a second servo motor that drives the first down feeding roller group to rotate. The second down feeding drive source 52 includes a second down feeding roller group that pulls the second down yarn 32 and a third servo motor that drives the second down feeding roller group to rotate. The speed of the first servo motor, the second servo motor and the third servo motor can be adjusted through a control panel.

[0044] S3. When the weaving process moves from the jacquard section 12 to the pile section 11, if the first pile yarn 31 needs to be raised, the first pile feeding drive source 51 is controlled to increase the conveying speed of the first pile yarn 31 from the second speed to exceed the third speed, and then decreases to the third speed, while maintaining the third speed for weaving the pile section 11; if the second pile yarn 32 needs to be raised, the second pile feeding drive source 52 is controlled to increase the conveying speed of the second pile yarn 32 from the fourth speed to exceed the fifth speed, and then decreases to the fifth speed, while maintaining the fifth speed for weaving the pile section 11.

[0045] When the weaving process moves from the pile section 11 to the jacquard section 12, it is determined whether the first pile yarn 31 and the second pile yarn 32 are raising the pile. If the first pile yarn 31 is raising the pile, the first pile feeding drive source 51 is controlled to reduce the conveying speed of the first pile yarn 31 from the third speed to below the second speed, and then rises back to the second speed, maintaining the second speed for weaving the pile section 11; if the second pile yarn 32 is raising the pile, the second pile feeding drive source 52 is controlled to reduce the conveying speed of the second pile yarn 32 from the fifth speed to below the fourth speed, and then rises back to the fourth speed, maintaining the fourth speed for weaving the pile section 11.

[0046] When a color zone change is required in the pile segment 11, taking the change from only the first pile yarn 31 to only the second pile yarn 32 as an example, the first pile feeding drive source 51 is controlled to reduce the conveying speed of the first pile yarn 31 from the third speed to below the second speed, then rises back to the second speed and maintains the second speed for weaving the pile segment 11. At the same time, the second pile feeding drive source 52 is controlled to increase the conveying speed of the pile yarn 3 from the fourth speed to above the fifth speed, then drops to the fifth speed and maintains the fifth speed for weaving the pile segment 11. Other transformation forms are similar and will not be described in detail.

[0047] S4. The woven ribbon is now a structure in which two ribbons are connected at the pile section. That is, the jacquard section of the upper ribbon and the lower ribbon are separated, while the pile section is connected by the pile yarn. At this time, the pile yarn of the pile section is cut by a cutter to achieve separation.

[0048] The present invention discloses an intermittent jacquard velvet ribbon and its weaving method, which results in a ribbon with high aesthetic appeal, and the pattern is not easily deformed or disappeared. Furthermore, by improving the weaving method, the tightness of the jacquard section and the looseness of the pile section are ensured, thereby improving the aesthetic appeal of the transition area of ​​the ribbon structure.
