Description
Technical Field
[0001] The invention relates to the technical field of textiles, in particular to a height-fixing sheet for single-shed weaving velvet and a weaving method of Zhang satin velvet using the sheet. Background Art
[0002] The single-shed velvet loom is a commonly used device in traditional weaving. When weaving double-layer velvet fabric, it introduces the weft yarn through a single shed and then weaves the upper and lower layers alternately.
[0003] With the development of textile technology and the increase of market demand, the single-shed velvet loom for double-layer velvet fabric has gradually revealed its limitations in weaving efficiency, fabric quality and variety. The weaving process of silk velvet products with unique style in double-layer fabrics has put forward higher requirements on the performance of the loom; especially jacquard silk velvet fabric has a unique style and noble temperament. Its ground is smooth and flat, the flower part has prominent velvet, and the three-dimensional sense is very strong. The process is complex and delicate, which requires superb technology and rich experience. The existing double-layer double-shed equipment is not suitable for silk velvet because it is a medium-weight and heavy-duty loom. The single-shed velvet loom is not suitable for weaving silk velvet. For example, the satin surface of Zhang velvet satin is larger than the pile surface area, and the pile area is relatively small. Therefore, it is difficult to stretch the pile to a uniform height during weaving, and it is also impossible to make the satin surface smooth. If you want to make the pile height consistent and the satin surface smooth, it is best to use a fixed height plate that can only be used in a double-layer double-shed loom. Only in this way can the pile height be consistent and the pile surface be smooth.
[0004] To sum up, the existing double-layer double-shuttle looms are not good at weaving silk, but the single-shuttle looms are difficult to control the height of the pile and the smoothness of the satin, and they cannot use fixed height plates, and weaving in this way is unworthy of the traditional title of intangible cultural heritage; therefore, the textile industry is constantly exploring new weaving technologies and equipment for velvet weaving equipment to improve production efficiency and product quality and adapt to the production of Zhang satin velvet; how to make single-shuttle velvet looms weave Zhang velvet satin in this good market situation of supply exceeding demand has immeasurable prospects. Summary of the Invention
[0005] The main purpose of the present invention is to address the shortcomings of single-shed looms when weaving velvet products such as Zhangduan velvet, and to invent a height-fixing plate for single-shed weaving velvet and a weaving method for Zhangduan velvet; wherein, the design of the height-fixing plate is intended to optimize the opening and closing process of the shed, improve the efficiency and stability of the introduction of the weft yarn, thereby improving the quality and appearance of the fabric, making the pile height of the Zhangduan velvet uniform, and making the satin surface of the Zhangduan velvet smooth, and at the same time, combined with a specific weaving process, it is possible to weave Zhangduan velvet products with unique style and high quality; The height setter is a special equipment for double-shed weaving velvet and other spacer fabrics. The height setter passes through the reed teeth and is parallel to the warp yarns. The upper rapier runs from the top of the height setter and the lower rapier runs from the bottom of the height setter. The single-shed loom has only one shed, that is, only one rapier. The height setter is like a wall, blocking the operation of the rapier of the single shed. However, the height setter can make the pile height of Zhang satin velvet consistent and make the satin surface of Zhang satin velvet smooth. How to use the height setter on the single-shed loom is the ideal of all single-shed loom factories that want to weave Zhang satin velvet.
[0006] In order to achieve the above technical objectives or solve the above technical problems, the specific technical solutions of the present invention are as follows: In one aspect, the present invention provides a height-fixing sheet for single-shed weaving velvet, comprising: Special heald frames, special healds, fixed height lifting plates, fixed height inserts and fixed high pressure bars; The upper part of the special heald frame is provided with a heald lifting spring for lifting upward, and the lower part of the special heald frame is connected with a pulling wire rope, and the pulling wire rope is connected to the heald lifting dobby on the upper side of the special heald frame through a diverting pulley; The front end of the height-fixing inserting piece is inserted between the upper and lower layers of the velvet cloth and is pressed by the high-tension fixing bar so that the height-fixing inserting piece cannot move up and down.
[0007] A hinge is provided at the rear end of the height-fixing insert; The height-fixing lifting piece is inserted into the steel reed, and there are steel reed pieces on both sides; one end of the height-fixing lifting piece is hinged to the hinge at the rear end of the height-fixing insertion piece, and the hinge angle between the height-fixing lifting piece and the height-fixing insertion piece is semicircular, and the other end of the height-fixing lifting piece is connected to the special heald, and a long kidney hole is provided at the connection between the height-fixing lifting piece and the special heald, and the opening of the long kidney hole is inserted between the upper cover cap and the lower cover cap of the special heald, and the middle of the height-fixing lifting piece is waisted, which is convenient for the rapier to run without collision; The special heald is arranged on the special heald frame, and the upper and lower ends of the long kidney hole provided at the connection position of the special heald corresponding to the height-fixing lifting piece are provided with an upper cover cap and a lower cover cap for controlling the lifting of the lifting piece.
[0008] After the special heald frame is lifted and lowered by the heald lifting dobby, it passes through the special heald frame, special heald, fixed height lifting plate, fixed height insertion plate, fixed high pressure bar and related connecting parts and single shuttle rapier for weft insertion, and weft yarn a is formed on the fixed height insertion plate and weft yarn b is formed under the fixed height insertion plate.
[0009] The special heald frame and the special heald can also pull the height-fixing inserting piece so that it no longer moves back and forth with the cloth surface due to the lifting movement of the upper cover cap, the lower cover cap and the kidney long hole and the intermittent beating movement of the reed.
[0010] further: When the device is installed, it is set so that when the fixed height lifting plate sinks, the rapier can pass above the fixed height lifting plate and the upper weft yarn a is introduced by the rapier; when the fixed height lifting plate rises, the rapier can pass below the fixed height lifting plate and the lower weft yarn b is introduced by the rapier.
[0011] further: When the device is in operation, when the heald dobby is lifted up, the special heald frame will be sunk down through the pulling wire rope of the steering pulley, and the special heald in the special heald frame will also sink down at the same time, thereby driving the fixed height lifting plate to sink down. At this time, the rapier and the weft yarn thrown by the rapier will pass over the fixed height lifting plate; when the steel reed beats the weft, since the hinged joint of the fixed height lifting plate and the fixed height insert plate is connected in a semicircular arc shape, the weft yarn is hit and squeezed by the steel reed, and the weft yarn passing over the fixed height lifting plate will be hit and squeezed onto the fixed height insert plate, thereby forming an upper layer of weft yarn a above the fixed height insert plate; When the device is running, when the heald lifting dobby sinks, the pulling wire rope of the steering pulley will release the downward traction force of the special heald frame, but it will be pulled upward by the upward heald hanging spring, and the special heald in the special heald frame will also rise at the same time, thereby driving the fixed height lifting plate to rise. At this time, the rapier and the weft yarn thrown by the rapier will pass under the fixed height lifting plate; when the steel reed beats the weft, since the hinged joint of the fixed height lifting plate and the fixed height insertion plate is connected in a semicircular shape, the weft yarn is hit and squeezed by the steel reed, and the weft yarn passing under the fixed height lifting plate is hit and squeezed to the bottom of the fixed height insertion plate, thereby forming a lower layer of weft yarn b under the fixed height insertion plate.
[0012] further: The special heald frame is installed at the end of all ground warp heald frames because when the height-fixing lifting plate is raised or lowered, there is a basic common sense that the hypotenuse of a right triangle is larger than the right angle side. Therefore, when the height-fixing lifting plate is raised or lowered, the long hole of the waist where it is connected to the special heald will extend out to avoid colliding with other warp threads. Therefore, it is designed to be installed at the end of all ground warp heald frames. When the heald dobby is lifted up, the special heald frame will sink, and when the heald dobby is sunk, the special heald frame will rise. Considering that the extrusion force on the weft yarn caused by the sinking special heald frame is greater than the extrusion force on the weft yarn caused by the rising special heald frame, it is designed to be a reverse hanging form compared with the normal one.
[0013] further: When the heald dobby is sunk, the special heald frame will rise, and the long hole of the kidney where the height-fixing lifting piece is connected to the special heald will also rise, thereby causing the connecting end of the height-fixing lifting piece to move upward. However, because the other end of the height-fixing lifting piece is connected to the height-fixing inserting piece, the height-fixing inserting piece is inserted between the upper and lower cloths and is pressed by the high-pressure bar and cannot move. Therefore, only the end of the height-fixing lifting piece connected to the long hole of the kidney moves upward, thus forming a shed. When the heald dobby is lifted up, the special heald frame will sink, and the long hole of the kidney at the connection between the fixed height lifting piece and the special heald will also drop, thereby causing the connecting end of the fixed height lifting piece to move downward. However, because the other end of the fixed height lifting piece is connected to the fixed height insertion piece, the fixed height insertion piece is inserted between the upper and lower cloths and is pressed by the fixed high pressure bar and cannot move. Therefore, only the end of the fixed height lifting piece at the connection with the long hole of the kidney moves downward, thus forming a shed.
[0014] further: When the reed beats the weft, the weft yarn is hit and squeezed by the reed because the hinge between the height-fixing lifting plate and the height-fixing insert is in a semicircular arc shape. The weft yarn passing under the height-fixing lifting plate is hit and squeezed to the bottom of the height-fixing insert, and the weft yarn passing above the height-fixing lifting plate is hit and squeezed to the top of the height-fixing insert. When the weft yarn is hit and squeezed to the top or bottom of the height-fixing insert, the pile warp yarn will also follow the weft yarn from the weaving unfixed area into the weaving fixed area, so that the pile will also be fixed up and down by the height-fixing insert to form a fixed height pile. When the weft yarn is hit and squeezed to the top or bottom of the height-fixing insert, the satin warp yarn will also follow the weft yarn into the weaving shaping area, so that the ground warp yarn is also fixed up and down by the height-fixing insert at a certain distance to form a flat ground structure, namely satin.
[0015] On the other hand, the present invention provides a method for weaving a single-shed weaving velvet height-fixing sheet for Zhang satin velvet, the weaving method comprising the following steps: Under the premise of weaving velvet, perform the following steps: When weaving the upper layer, the heald dobby of the special heald frame is controlled to lift up, allowing the upper weft yarn to pass above the fixed height lifting plate and be hit and squeezed by the reed to the top of the front fixed height insertion plate to form the weft yarn a of the upper fabric; When weaving the lower layer, the heald dobby of the special heald frame is controlled not to be lifted up, so that the lower weft yarn passes under the fixed height lifting piece and is hit and squeezed by the reed to the bottom of the front fixed height insertion piece to form the weft yarn b of the lower fabric.
[0016] further: When the weave of Zhangrong satin is a three-up-one-down twill, you can first weave the upper four wefts continuously, and then weave the lower four wefts, that is: First, lift the dobby arm of the special heald frame up four times to weave the upper layer three-up and one-down twill. Then the heald dobby of the special heald frame does not need to be lifted up four times, and the three-up-one-down twill weaving of the lower layer is carried out; Repeat this cycle and follow the normal process of making Zhangrong satin.
[0017] further: When the weave of Zhangrong satin is eight-weave satin, you can first weave the upper four wefts, then weave the lower four wefts, then weave the upper four wefts again, and then weave the lower four wefts again, that is: First, lift the dobby arm of the special heald frame four times to weave the first four wefts of the eight satin pieces on the upper layer; Then, the heald-lifting dobby of the special heald frame does not need to be lifted up four times to weave the first four wefts of the eight satin pieces on the lower layer; Then the heald dobby of the special heald frame is raised four times to weave the four wefts of the eight satins on the upper layer; Then the heald dobby of the special heald frame does not need to be lifted up four times to weave the four wefts of the eight satins on the lower layer; By repeating this process, the fluff of Zhangrong satin will not become scarce due to the eight pieces of satin, and the surface of Zhangrong satin will not be broken due to the four shuttles going up and four shuttles going down. The normal process of Zhangrong satin can be used.
[0018] The beneficial effects of the present invention are: based on the existence of the fixed height plate, not only can higher-grade velvet be woven on a single-shed loom, but the pile height of the Zhangduan velvet can also be made consistent, and the satin surface of the Zhangduan velvet can be made smooth, so that it meets the properties of all-silk color-woven jacquard velvet fabrics and has a unique style and noble temperament requirements; it solves the problem that the current double-shed double-rapier loom has a fixed height plate, but it is difficult to make silk and it is difficult to weave Zhangduan satin because it belongs to a medium-weight and heavy-weight loom; it also solves the problem that the current single-shed single-rapier loom can be light in weight and can make silk, but it is difficult to complete the weaving of Zhangduan satin with consistent pile and smooth satin surface, and is very popular.

[0021] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.
[0022] In the description of the present invention, it should be noted that the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all of the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention. Example 1
[0023] This embodiment provides a height-fixing sheet for single-shed weaving velvet, such as Figure 1~Figure 2 Shown, including: Special heald frame 1, special heald 2, height-fixing lifting plate 3, height-fixing insert plate 4 and high-pressure fixing bar 5; The upper part of the special heald frame 1 is provided with a heald lifting spring 9.1 for lifting upwards, and the lower part of the special heald frame 1 is connected with a pulling wire rope 9.2, and the pulling wire rope 9.2 is connected to the heald lifting dobby 9.4 on the upper side of the special heald frame 1 through a diverting pulley 9.3; The front end of the height-fixing inserting piece 4 is inserted between the upper and lower layers of the velvet cloth and is pressed by the high-voltage-fixing bar 5 so that it cannot move up and down.
[0024] The rear end of the height-fixing insert 4 is provided with a hinge; The height-fixing lifting piece 3 is inserted into the reed 6, and there are reed 6 reed pieces on both sides; one end of the height-fixing lifting piece 3 is hinged to the hinge at the rear end of the height-fixing insertion piece 4, and the hinge angle of the height-fixing lifting piece 3 and the height-fixing insertion piece 4 is semicircular, and the other end of the height-fixing lifting piece 3 is connected to the special heald 2. A kidney long hole 3.2 is provided at the connection between the height-fixing lifting piece 3 and the special heald 2, and the opening of the kidney long hole 3.2 is inserted between the upper cover cap and the lower cover cap of the special heald 2. The middle of the height-fixing lifting piece 3 is waisted, which is convenient for the rapier 7 to run without collision; The special heald 2 is arranged on the special heald frame 1, and the upper and lower ends of the kidney long hole 3.2 provided at the connection position of the special heald 2 corresponding to the height-fixing lifting piece 3 are provided with an upper cover cap and a lower cover cap for controlling the lifting of the lifting piece.
[0025] After the special heald frame 1 is lifted and lowered by the heald lifting dobby 9.4 machine, it passes through the special heald frame 1, special heald 2, fixed height lifting piece 3, fixed height insertion piece 4, fixed high pressure bar 5 and related connecting parts and single shuttle rapier 7 for weft insertion, and the weft yarn a is formed on the fixed height insertion piece 4 and the weft yarn b is formed under the fixed height insertion piece 4.
[0026] The special heald frame 1 and the special heald 2 can also pull the height-fixing insert 4 so that it no longer moves back and forth with the cloth surface due to the lifting movement of the upper cap, the lower cap and the kidney long hole 3.2 and the intermittent beating movement of the reed 6.
[0027] further: When the device is installed, it is set so that when the height-fixing lifting plate 3 sinks, the rapier 7 can pass above the height-fixing lifting plate 3, and the upper weft yarn a is introduced by the rapier 7; when the height-fixing lifting plate 3 rises, the rapier 7 can pass below the height-fixing lifting plate 3, and the lower weft yarn b is introduced by the rapier 7.
[0028] further: When the device is running, when the heald lifting dobby 9.4 is lifted up, the pulling wire rope 9.2 of the diverting pulley 9.3 will sink the special heald frame 1, and the special heald 2 in the special heald frame 1 will also sink at the same time, thereby driving the fixed height lifting piece 3 to sink. At this time, the rapier 7 and the weft yarn thrown by the rapier 7 will pass over the fixed height lifting piece 3; when the steel reed 6 beats up the weft, since the hinged joint of the fixed height lifting piece 3 and the fixed height insertion piece 4 is connected in a semicircular arc shape, the weft yarn is hit and squeezed by the steel reed 6, and the weft yarn passing over the fixed height lifting piece 3 will be hit and squeezed onto the fixed height insertion piece 4, thereby forming an upper layer of weft yarn a above the fixed height insertion piece 4; When the device is running, when the heald lifting dobby 9.4 sinks, the pulling wire rope 9.2 of the diverting pulley 9.3 will release the downward traction force of the special heald frame 1, but it will be pulled upward by the upward heald tension spring 9.1, and the special heald 2 in the special heald frame 1 will also rise at the same time, thereby driving the fixed height lifting piece 3 to rise. At this time, the rapier 7 and the weft yarn cast by the rapier 7 will pass under the fixed height lifting piece 3; when the reed 6 beats the weft, since the hinged joint of the fixed height lifting piece 3 and the fixed height insertion piece 4 is connected in a semicircular shape, the weft yarn is hit and squeezed by the reed 6, and the weft yarn passing under the fixed height lifting piece 3 is hit and squeezed to the bottom of the fixed height insertion piece 4, thereby forming a lower layer of weft yarn b under the fixed height insertion piece 4.
[0029] further: The special heald frame 1 is installed at the end of all the ground warp heald frames because when the height-fixing lifting plate 3 is raised or lowered, there is a basic common sense that the hypotenuse of a right triangle is greater than the right angle side. Therefore, when the height-fixing lifting plate 3 is raised or lowered, the long hole 3.2 of the kidney where it is connected to the special heald 2 will extend out, which will avoid colliding with other warp threads. Therefore, it is designed to be installed at the end of all the ground warp heald frames; When the heald lifting dobby 9.4 is lifted up, the special heald frame 1 will sink, and when the heald lifting dobby 9.4 is sunk, the special heald frame 1 will rise. Considering that the extrusion force on the weft yarn caused by the sinking of the special heald frame 1 is greater than the extrusion force on the weft yarn caused by the rising of the special heald frame 1, it is designed to be an anti-hanging form compared with the normal one.
[0030] further: When the heald dobby 9.4 is sunk, the special heald frame 1 will rise, and the kidney long hole 3.2 at the connection between the height-fixing lifting piece 3 and the special heald 2 will also rise, thereby causing the connection end of the height-fixing lifting piece 3 to move upward. However, because the other end of the height-fixing lifting piece 3 is connected to the height-fixing inserting piece 4, the height-fixing inserting piece is inserted between the upper and lower cloth layers and is pressed by the high-pressure bar 5 and cannot move. Therefore, only the end of the height-fixing lifting piece 3 at the connection with the kidney long hole 3.2 moves upward, thereby forming a shed. When the heald dobby 9.4 is lifted upward, the special heald frame 1 will sink, and the kidney long hole 3.2 at the connection between the fixed height lifting piece 3 and the special heald 2 will also drop, thereby causing the connecting end of the fixed height lifting piece 3 to move downward. However, because the other end of the fixed height lifting piece 3 is connected to the fixed height insertion piece 4, the fixed height insertion piece 4 is inserted between the upper and lower cloths and is pressed by the fixed high pressure bar 5 and cannot move. Therefore, only the end of the fixed height lifting piece 3 at the connection with the kidney long hole 3.2 moves downward, thereby forming a shed.
[0031] further: When the reed 6 beats the weft, since the hinge between the height-fixing lifting piece 3 and the height-fixing insert piece 4 is connected in a semicircular arc shape, the weft yarn is hit and squeezed by the reed 6. The weft yarn passing under the height-fixing lifting piece 3 is hit and squeezed to the bottom of the height-fixing insert piece 4, and the weft yarn passing above the height-fixing lifting piece 3 is hit and squeezed to the top of the height-fixing insert piece 4. When the weft yarn is hit and squeezed to the top or bottom of the height-fixing insert 4, the pile warp yarn will also follow the weft yarn from the weaving unfixed area into the weaving fixed area, so that the pile will also be fixed up and down by the height-fixing plate to form a fixed height pile. When the weft yarn is hit and squeezed to the top or bottom of the height-fixing insert 4, the satin warp yarn will also follow the weft yarn into the weaving shaping area, so that the ground warp yarn is also fixed up and down by the height-fixing insert 4 at a certain distance to form a flat ground structure, namely satin. Example 2
[0032] This embodiment is based on the same inventive concept as the single-shed weaving velvet height-fixing sheet described in Example 1, and provides a method for weaving satin velvet with a single-shed weaving velvet height-fixing sheet, such as Figure 3~Figure 4 As shown, the method includes the following steps: Under the premise of weaving velvet, perform the following steps: When weaving the upper layer, the heald dobby 9.4 of the dedicated heald frame 1 is controlled to lift upward, allowing the upper weft yarn to pass above the fixed height lifting piece 3 and be hit and squeezed by the reed 6 to the top of the front fixed height insertion piece 4 to form the weft yarn a of the upper fabric; When weaving the lower layer, the heald dobby 9.4 of the special heald frame 1 is controlled not to be lifted up, so that the lower weft yarn passes under the fixed height lifting piece 3 and is hit and squeezed by the reed 6 to the bottom of the front fixed height insertion piece 4 to form the weft yarn b of the lower fabric.
[0033] further: When the weave of Zhangrong satin is a three-up-one-down twill, you can first weave the upper four wefts continuously, and then weave the lower four wefts, that is: First, lift the dobby 9.4 of the special heald frame 1 four times to carry out the upper layer three-up and one-down twill weaving; Then, the heald lifting dobby 9.4 of the special heald frame 1 does not need to be lifted up four times to carry out the three-up-one-down twill weaving of the lower layer; Repeat this cycle and follow the normal process of making Zhangrong satin.
[0034] further: When the weave of Zhangrong satin is eight-weave satin, you can first weave the upper four wefts, then weave the lower four wefts, then weave the upper four wefts again, and then weave the lower four wefts again, that is: First, lift the dobby 9.4 of the special heald frame 1 four times to weave the first four wefts of the eight satin pieces on the upper layer; Then, the dobby 9.4 of the special heald frame 1 is not required to be lifted up four times to weave the first four wefts of the eight satin pieces in the lower layer; Then the dobby 9.4 of the special heald frame 1 is lifted up four times to weave the four wefts of the eight satins on the upper layer; Then, the dobby 9.4 of the special heald frame 1 is not required to be lifted up four times to weave the back four wefts of the eight satins in the lower layer; By repeating this process, the fluff of Zhangrong satin will not become scarce due to the eight pieces of satin, and the surface of Zhangrong satin will not be broken due to the four shuttles going up and four shuttles going down. The normal process of Zhangrong satin can be used.
[0035] The above description is merely an implementation of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.

The height-fixing plate for single-shed weaving velvet according to claim 1, characterized in that: When the height-fixing plate for single-shed velvet weaving is installed, it is set so that when the height-fixing lifting plate is sunk, the rapier passes above the height-fixing lifting plate and the upper weft yarn a is introduced by the rapier; when the height-fixing lifting plate is raised, the rapier passes below the height-fixing lifting plate and the lower weft yarn b is introduced by the rapier; When the single-shed velvet weaving fixed height piece is in operation, when the heddle lifting dobby is lifted up, the special heddle frame is sunk down through the pulling wire rope of the diverting pulley, and the special heddle in the special heddle frame is also sunk down at the same time, thereby driving the fixed height lifting piece to sink down, so that the rapier and the weft yarn thrown by the rapier will pass over the fixed height lifting piece; when the steel reed beats the weft, since the hinged joint of the fixed height lifting piece and the fixed height insert piece is connected in a semicircular arc shape, the weft yarn is hit and squeezed by the steel reed, and the weft yarn passing over the fixed height lifting piece is hit and squeezed onto the fixed height insert piece, thereby forming an upper layer of weft yarn a above the fixed height insert piece; When the single-shed velvet weaving fixed height piece is in operation, when the heddle lifting dobby sinks, the pulling wire rope of the diverting pulley will release the downward traction force of the special heddle frame, but it will be pulled upward by the upward heddle tension spring, and the special heddle in the special heddle frame will also rise at the same time, thereby driving the fixed height lifting piece to rise, so that the rapier and the weft yarn thrown by the rapier will pass under the fixed height lifting piece; when the steel reed beats the weft, since the hinged joint of the fixed height lifting piece and the fixed height insertion piece is semicircular and rounded, the weft yarn is hit and squeezed by the steel reed, and the weft yarn passing under the fixed height lifting piece is hit and squeezed to the bottom of the fixed height insertion piece, thereby forming a lower layer of weft yarn b under the fixed height insertion piece.
3. The height-fixing plate for single-shed weaving velvet according to claim 1, characterized in that: In the height-fixing plate for single-shed weaving velvet, the dedicated heald frame is installed at the rear of all ground warp heald frames to avoid collision with other warp yarns; In the described height-fixing plate for single-shed weaving velvet, when the heddle-lifting dobby is lifted up, the special heddle frame will sink, and when the heddle-lifting dobby is sunk, the special heddle frame will rise. Based on the fact that the extrusion force on the weft yarn when the special heddle frame sinks is greater than the extrusion force on the weft yarn when the special heddle frame rises, it is set into a reverse hanging form compared with the normal form.
4. The height-fixing plate for single-shed weaving velvet according to claim 1, characterized in that: In the single-shed weaving velvet fixed height piece, when the heddle dobby is sunk, the special heddle frame will rise, and the long hole of the kidney at the connection between the fixed height lifting piece and the special heddle will also rise, thereby causing the connection end of the fixed height lifting piece to move upward. However, because the other end of the fixed height lifting piece is connected to the fixed height inserting piece, the fixed height inserting piece is inserted between the upper and lower cloth layers and is pressed by the fixed high pressure bar. Finally, only the end of the fixed height lifting piece connected to the long hole of the kidney moves upward, thereby forming a shed. In the single-shed weaving velvet fixed height piece, when the heddle dobby is lifted up, the special heddle frame will sink, and the long hole of the kidney at the connection between the fixed height lifting piece and the special heddle will also drop, thereby causing the connecting end of the fixed height lifting piece to move downward. Because the other end of the fixed height lifting piece is connected to the fixed height insertion piece, the fixed height insertion piece is inserted between the upper cloth and the lower cloth, and is pressed by the fixed high pressure bar. Finally, only the end of the fixed height lifting piece at the connection with the long hole of the kidney moves downward, thus forming a shed.
5. The height-fixing plate for single-shed weaving velvet according to claim 1, characterized in that: In the single-shed velvet weaving height-fixing piece, when the reed beats the weft, the weft yarn is struck and squeezed by the reed due to the semicircular arc connection between the hinge of the height-fixing lifting piece and the height-fixing insert piece. The weft yarn passing under the height-fixing lifting piece is struck and squeezed to the bottom of the height-fixing insert piece, and the weft yarn passing above the height-fixing lifting piece is struck and squeezed to the top of the height-fixing insert piece. When the weft yarn is hit and squeezed to the top or bottom of the height-fixing insert, the pile warp yarn will also follow the weft yarn from the weaving unfixed area into the weaving fixed area, so that the pile will also be fixed up and down by the height-fixing insert to form a fixed height pile. When the weft yarn is hit and squeezed to the top or bottom of the height-fixing insert, the satin warp yarn will also follow the weft yarn into the weaving shaping area, so that the ground warp yarn is also fixed up and down by the height-fixing insert at a certain distance to form a flat ground structure, namely satin.
6. A method for weaving Zhang satin velvet using a height-fixing sheet for single-shed weaving velvet according to any one of claims 1 to 5, characterized in that: The weaving method comprises the following steps: Under the premise of weaving velvet, perform the following steps: When weaving the upper layer, the heald dobby of the special heald frame is controlled to lift up, allowing the upper weft yarn to pass above the fixed height lifting plate and be hit and squeezed by the reed to the top of the front fixed height insertion plate to form the weft yarn a of the upper fabric; When weaving the lower layer, the heald dobby of the special heald frame is controlled not to be lifted up, so that the weft yarn of the lower layer passes under the fixed height lifting plate and is hit and squeezed by the reed to the bottom of the front fixed height insertion plate to form the weft yarn b of the lower fabric. When the weave of Zhangrong satin is three-up-one-down twill, the upper four wefts can be woven continuously first, and then the lower four wefts can be woven. Specifically, the following steps are: first, the heald dobby of the special heald frame is lifted up four times to weave the upper three-up-one-down twill; then, the heald dobby of the special heald frame is not lifted up four times to weave the lower three-up-one-down twill; this cycle is repeated according to the normal process of Zhangrong satin. When the weaving of Zhangrong satin is an eight-piece satin texture, you can first continuously weave the upper four wefts, then the lower four wefts, and then weave the upper four wefts again, and then weave the lower four wefts again, specifically including: first let the special heald frame's heald dobby lift up four times to weave the first four wefts of the upper eight satins; then let the special heald frame's heald dobby not lift up four times to weave the first four wefts of the lower eight satins; again let the special heald frame's heald dobby not lift up four times to weave the back four wefts of the upper eight satins; again let the special heald frame's heald dobby not lift up four times to weave the back four wefts of the lower eight satins; and so on, so that the Zhangrong satin fluff will not be sparse due to the eight satins, and the Zhangrong satin surface will not be broken due to the four shuttles going up and four shuttles going down, and you just need to operate according to the normal process of Zhangrong satin.
