Description

Technical Field

[0001] The present invention relates to the technical field of jacquard fabric equipment, and particularly to a production process of water-soluble yarn jacquard fabric. Background Art

[0002] Water-soluble yarn jacquard fabric is a special fabric that combines water-soluble yarn and jacquard technology. Combined with high-quality fibers such as Lenzing rayon, the fabric has both a soft and thick texture and environmental protection characteristics, with excellent breathability and hygroscopicity, and is widely used in the fields of fashion, home, and industry.

[0003] As disclosed in the publication number: CN115574552A, a production process of all-cotton water-soluble yarn jacquard fabric includes the following steps: S1. Prepare raw materials, prepare all-cotton yarn and water-soluble yarn, where the all-cotton yarn accounts for 80 - 90% of the total amount, and the water-soluble yarn accounts for 10 - 20% of the total amount; S2. Weaving, draw the pattern in the computer according to the required pattern, arrange the needles with all-cotton yarn and water-soluble yarn according to the pattern of the computer pattern, and the dosage of both is determined according to the pattern. The present invention can remove the residual fluff on the fabric surface while drying the fabric, thereby improving the quality of the fabric production. At the same time, it can continuously discharge the condensed water on the inner wall of the drying box, thereby ensuring the dryness inside the drying box. At the same time, it can prevent the condensed water from dripping on the dried fabric, thereby ensuring the continuous drying effect of the fabric.

[0004] Although the above drying equipment can dry the fabric, the drying efficiency of the drying equipment in the above process for the fabric is insufficient, and the efficiency of scraping the fabric fluff is also insufficient. Therefore, a production process of water-soluble yarn jacquard fabric is needed to solve the problems raised above. Summary of the Invention

[0005] The purpose of the present invention is to provide a production process of water-soluble yarn jacquard fabric to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A production process of water-soluble yarn jacquard fabric includes the following steps:

[0007] S1: Prepare raw materials, mix all-cotton yarn with modified PVA water-soluble yarn, where the mixed all-cotton yarn accounts for 85% of the total amount, and the PVA water-soluble yarn accounts for 15% of the total amount;

[0008] S2: Weave the raw materials, use a jacquard loom, arrange the PVA water-soluble yarn according to a preset pattern, and the mixed all-cotton yarn forms a base;

[0009] S3: Dyeing, for the completed jacquard fabric, carry out low-temperature reactive dyeing, the temperature of the dyeing is 60 - 80 °C, and then carry out fixing and then washing with water;

[0010] S4: High-temperature dissolution. The jacquard fabric after dyeing and water washing is treated with 180°C steam, and the water-soluble yarn dissolves to form a hollow pattern.

[0011] S5: Dehumidify the fabric. Use a dehumidification device to remove the condensed water from the processed fabric.

[0012] S6: Dry the fabric. Through a drying and scraping module, adsorb and scrape the fluff on the outside of the fabric, and at the same time dry the fabric unidirectionally or bidirectionally, and synchronously discharge the remaining condensed water vapor.

[0013] Preferably, the drying and scraping module includes a support box body. Two groups of adjustable cylinders for guiding are arranged on both the upper and lower parts of the support box body. Drying and dehumidifying devices are arranged at the output ends of the upper and lower two groups of adjustable cylinders. Linear bearings are arranged on the inner end surface of the support box body corresponding to each drying and dehumidifying device. Guide chucks are arranged at the centers of the front and rear parts of the support box body, and two support guide rollers are rotatably clamped inside the guide chucks. Transmission gears are arranged at the centers of the side ends of the two support guide rollers, and a servo motor is arranged on the side end surface of the guide chuck corresponding to the support guide roller.

[0014] Preferably, the drying and dehumidifying device includes a positioning slide. A cylinder guide seat is fixedly arranged at the center of the upper end surface of the positioning slide. Two guide gears are rotatably clamped inside the positioning slide, and a drying turntable is fixedly arranged through the lower end surfaces of the two guide gears. Hair removal scrapers are equidistantly arranged on the lower end surface of the drying turntable. Sealing rotating seats are fixedly arranged on the upper end surfaces of the guide gears, and air guiding devices are hermetically and rotatably clamped inside the two sealing rotating seats. A stepping motor is fixedly arranged at the center of the upper end surface of the positioning slide.

[0015] Preferably, the air guiding device includes a corrugated pipe. A butt joint conduit is arranged at the center of the upper end surface of the corrugated pipe, and a sealing rotating ring is arranged at the center of the lower end surface of the corrugated pipe.

[0016] Preferably, the corrugated pipe is hermetically and rotatably clamped with the sealing rotating seat through the sealing rotating ring and then with the upper part of the guide gear. The hermetic and rotational clamping of the sealing rotating seat and the sealing rotating ring can provide a sufficient guiding basis for the subsequent drying turntable to scrape the fluff and conduct air for drying the fabric.

[0017] Preferably, the two groups of guiding gears are meshed and connected, and the upper and lower two groups of drying and dehumidifying devices face each other, which can effectively improve the transmission stability of the equipment, and then improve the efficiency of subsequent fabric drying.

[0018] Preferably, the positioning sliding seat is slidably clamped on the inner end face of the support box body through the linear sliding shaft and the linear bearing, which can effectively improve the stability of the subsequent up-and-down sliding guidance of the drying and dehumidifying device inside the support box body.

[0021] 1. By setting the drying and dehumidifying device, when drying and dehumidifying the fabric, the upper and lower two groups of stepping motors can synchronously provide sufficient power for the two groups of drying turntables through the guiding gears, so that the drying turntables can drive the hair removal scrapers to rotate at high speed, thereby synchronously scraping the fluff of the fabric conveyed by the two groups of support guide rollers. Moreover, the two groups of drying turntables can conduct drying gas unidirectionally, and cooperate with the scraping of the hair removal scrapers to synchronously remove the remaining condensed water vapor and fluff, effectively improving the efficiency of the equipment for drying and processing the fabric.

[0022] 2. By setting the air guiding device and the adjustable cylinder, when drying and removing hair from the fabric, the adjustable cylinder can adjust the distance between the two groups of drying and dehumidifying devices for drying docking according to requirements, effectively improving the adaptability of the equipment for subsequent drying and removing hair from fabrics of different thicknesses. At the same time, the air guiding device can provide a sufficient support basis for unidirectional or bidirectional air guiding of the two groups of drying and dehumidifying devices, thereby improving the efficiency and adaptability of subsequent drying.

[0034] Embodiment 1

[0035] Please refer to Figures 1-6, An embodiment provided by the present invention: A production process of a water-soluble yarn jacquard fabric, comprising the following steps:

[0036] S1: Prepare raw materials, mix all-cotton yarn with modified PVA water-soluble yarn, where all-cotton yarn accounts for 85% of the total amount, and PVA water-soluble yarn accounts for 15% of the total amount;

[0037] S2: Weave the raw materials, use a jacquard loom, arrange the needles of the PVA water-soluble yarn according to a preset pattern, and the all-cotton yarn forms a base;

[0038] S3: Dyeing. For the completed jacquard fabric, perform low-temperature reactive dyeing at a temperature of 60 - 80 °C, and then carry out color fixation and water washing;

[0039] S4: High-temperature dissolution. The jacquard fabric after dyeing and water washing is treated with 180 °C steam, and the water-soluble yarn dissolves to form a hollow;

[0040] S5: Dehumidify the fabric. Remove the condensate from the processed fabric through a dehumidification device;

[0041] S6: Dry the fabric. Through a drying and scraping module, adsorb and scrape the fluff on the outside of the fabric, and at the same time dry the fabric unidirectionally or bidirectionally, and synchronously discharge the remaining condensate vapor.

[0042] As Figure 1 and Figure 2 , the drying and scraping module includes a support box body 7. Two groups of adjustable cylinders 8 for guiding are arranged on both the upper and lower parts of the support box body 7. Drying and dehumidification devices 2 are arranged at the output ends of the upper and lower two groups of adjustable cylinders 8. Linear bearings 1 are arranged on the inner end face of the support box body 7 corresponding to each drying and dehumidification device 2. Guide card seats 4 are arranged at the centers of the front and rear parts of the support box body 7. Two support guide rollers 5 are rotatably clamped on the inner end face of the guide card seats 4. Transmission gears 6 are arranged at the centers of the side ends of the two support guide rollers 5. A servo motor 3 is arranged on the side end face of the guide card seat 4 corresponding to the support guide roller 5.

[0043] As Figure 3 , Figure 4 and Figure 5, the drying and dehumidifying device 2 includes a positioning slide base 26. At the center of the upper end face of the positioning slide base 26, a cylinder guide base 25 is fixedly arranged. At the inner end face of the positioning slide base 26, two groups of guiding gears 27 are rotationally clamped. And at the lower end faces of the two groups of guiding gears 27, a drying turntable 28 is fixedly arranged through. At the lower end face of the drying turntable 28, hair removal scraping plates 211 are arranged at equal intervals. At the upper end faces of the guiding gears 27, sealing rotating seats 21 are fixedly arranged. And inside the two groups of sealing rotating seats 21, air guiding devices 23 are rotationally clamped in a sealed manner. At the center of the upper end face of the positioning slide base 26, a stepping motor 22 is fixedly arranged. At the output end of the synchronous pulley 29 and at the upper part of the guiding gear 27 at the side, synchronous pulleys 29 are arranged. And the two groups of synchronous pulleys 29 are meshed and connected through a synchronous belt 210. On the upper end face of the positioning slide base 26, linear slide shafts 24 are symmetrically arranged.

[0044] As Figure 6 , the air guiding device 23 includes a corrugated pipe 232. At the center of the upper end face of the corrugated pipe 232, a butt joint conduit 231 is arranged. And at the center of the lower end face of the corrugated pipe 232, a sealing rotating ring 233 is arranged.

[0045] The corrugated pipe 232 is adapted to the sealing rotating seat 21 through the sealing rotating ring 233 and is rotationally clamped in a sealed manner with the upper part of the guiding gear 27. The sealed rotational clamping of the sealing rotating seat 21 and the sealing rotating ring 233 can provide a sufficient guiding basis for subsequent scraping of fluff from the fabric by the drying turntable 28 and drying air guiding.

[0046] The two groups of guiding gears 27 are meshed and connected. The upper and lower two groups of drying and dehumidifying devices 2 are facing each other, which can effectively improve the stability of the equipment transmission and then improve the efficiency of subsequent fabric drying.

[0047] The positioning slide base 26 is adapted to the linear bearing 1 through the linear slide shaft 24 and is slidably clamped at the inner end face of the support box body 7, which can effectively improve the stability of the subsequent up and down sliding guidance of the drying and dehumidifying device 2 inside the support box body 7.

[0048] The feeding gap between the two groups of guiding clamping seats 4 and the drying gap between the two groups of drying and dehumidifying devices 2 are on the same straight line, which can effectively improve the accuracy and stability of subsequent fabric guiding and drying, thereby improving the efficiency of subsequent drying.

[0049] Working principle: Before use, the staff can import the jacquard fabric after the above-mentioned steps into the space between the front and rear groups of support guide rollers 5. At the same time, the external air supply ducts can be respectively connected to the upper and lower groups of docking ducts 231 to facilitate subsequent continuous drying air supply operations. And the staff can adjust the downward distance of the drying and dehumidifying device 2 through the adjustable cylinder 8 according to the thickness of the fabric, thereby improving the accuracy of drying and dehumidifying the jacquard fabric. Subsequently, the staff can start the two servo motors 3 and the adjustable cylinder 8 synchronously. When transporting the jacquard fabric, the servo motor 3 can drive the two support guide rollers 5 to rotate synchronously and reversely through the meshing of the two transmission gears 6, so that the front and rear groups of support guide rollers 5 can perform synchronous conveying operations on the jacquard fabric. When drying and dehumidifying the jacquard fabric, the stepping motors 22 located in the upper and lower parts can be started. At this time, the stepping motors 22 can drive the two guide gears 27 to rotate meshingly through the synchronous pulley 29 and the synchronous belt 210, so that the two guide gears 27 can synchronously drive the drying turntables 28 at the bottom to rotate synchronously and reversely. The two drying turntables 28 can quickly dry the moisture inside the jacquard fabric through one-way conduction. When performing one-way conduction, a group of air supply pipes above supply drying gas, and the one below conducts air extraction to complete the drying operation. At the same time, the hair scraping plate 211 at the bottom of the synchronous belt 210 can scrape the fluff on the outside of the jacquard fabric in all directions, and then discharge it through the guidance of the drying turntable 28.

[0050] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
