Description

Technical Field

[0001] The present invention relates to the field of velveteen processing, and particularly to a processing technology for super soft bamboo - joint velveteen cloth. Background Art

[0002] The processing technology for super soft bamboo - joint velveteen cloth is a technology used in the production of super soft bamboo - joint velveteen cloth.

[0003] The patent with the publication number CN221192584U discloses a dyeing vat for processing velveteen fabrics, including a base. A dyeing vat is fixedly installed at the top of the base. A fabric dyeing assembly is fixedly installed on the inner wall of the dyeing vat. The fabric dyeing assembly includes a feed pipe, a discharge pipe, and a spray dyeing machine. The spray dyeing machine includes a dye self - suction pump and a spray chamber for spraying dye on the fabric. Nozzles are uniformly fixedly installed on the outer wall of the bottom of the spray chamber. The soft bamboo - joint velveteen cloth is favored in the fields of high - grade clothing fabrics, home textiles, etc. due to its unique soft touch, remarkable warmth - keeping performance, and layered bamboo - joint texture. Dyeing is a key process in the production of super soft bamboo - joint velveteen cloth, and its quality directly determines the final quality and market value of the product. However, the dense and long fluff structure on the surface of such fabrics poses many challenges during the dyeing process. Among them, the problem of dyeing uniformity caused by fluff shedding is particularly prominent, seriously restricting the improvement of product quality and the development of the industry.

[0004] The fluff of the super soft bamboo - joint velveteen cloth is composed of tightly arranged fiber clusters and is fixed on the surface of the base cloth through a special process. During the dyeing process, the fabric has to experience a complex environment such as intense mechanical stirring, scour of the dye liquor, and temperature changes. On the one hand, the mechanical force will directly pull the connection part between the fluff and the base cloth, resulting in some fluff loosening and falling off. On the other hand, chemical auxiliaries (such as penetrants, leveling agents, etc.) in the dye liquor, while reducing the surface tension and promoting the diffusion of dyes, may chemically erode the bonding interface between the fluff and the base cloth, weakening the adhesion strength of the fluff and exacerbating the phenomenon of fluff shedding.

[0005] The fallen fluff will flow disorderly in the dyeing equipment with the dye liquor, having various effects on dyeing uniformity. First, the fallen fluff will adsorb a large amount of dyes, forming local high - concentration dye carriers. When these fluff adhere to the fabric surface or deposit in the corners of the equipment, it will cause too high dye concentration in local areas of the fabric, resulting in dyeing defects such as color spots and color streaks. Second, the fluff is randomly distributed in the dye liquor, interfering with the normal flow of the dye liquor and the diffusion path of the dyes, resulting in differences in the dye liquor concentration, temperature, and dyeing time contacted by different parts of the fabric, thereby affecting dyeing uniformity. Third, some fluff will entangle into clusters after falling off, hindering the contact between the dye liquor and the fabric, making it difficult for the entangled area to be fully dyed, forming color differences with different shades.

[0006] To solve the above problems, a processing technology for super-soft slub velveteen fabric is proposed for this purpose. Summary of the Invention

[0007] The purpose of the present invention is to provide a processing technology for super-soft slub velveteen fabric, which solves the problem that some fluff will entangle into groups after falling off, hindering the contact between the dye liquor and the fabric, making it difficult to fully dye the entangled area, and forming color differences with varying shades.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. A processing technology for super-soft slub velveteen fabric provided by the present invention. The slub texture structure of the super-soft slub velveteen fabric is special, and there is a large difference in fiber density between the slub and non-slub parts. Traditional dyeing is prone to uneven color. This device precisely controls the movement of the cylinder through a controller, driving the displacement of the air rod, fixed plate, and guide hole. Utilizing the inclined linear structure of the guide hole, in cooperation with the precise cooperation of the first guide rod, first chute, and first slider, the pressing plate is pushed to fully press the dye liquor deep into the slub texture.

[0025] 2. A processing technology for super-soft slub velveteen fabric provided by the present invention. During the dyeing process, the fluff dropped from the velveteen fabric will interfere with the dyeing effect and even reattach, resulting in fluff shedding. This device innovatively links the movement of the pressing plate with the fluff collection system. When the pressing plate moves, it drives the synchronous operation of the first and second filter meshes. With the unique vertical and inclined combined shape of the first and second guide grooves, the guide rod is guided to move horizontally along the chute, enabling the filter meshes to intercept the dropped fluff in real time and guiding it to the polytetrafluoroethylene adhesion plates on both sides. Even if the dye liquor pushes the fluff, it can be fixed by the adhesion plates, significantly reducing the probability of secondary attachment of the fluff, ensuring the quality of the fabric from the source, and reducing the losses caused by fluff shedding in subsequent processing.

[0026] 3. A processing technology for super-soft slub velveteen fabric provided by the present invention. If the fluff is not cleaned in time, it will block the fiber gaps of the fabric, hinder the penetration of the dye liquor, and prolong the dyeing time. This device effectively reduces the fluff impurities in the dye liquor through an efficient fluff collection system. After avoiding the blockage of the fiber gaps, the dye liquor can enter the fabric interior more smoothly, fully contact with the fibers to complete the dyeing reaction. This greatly improves the dyeing efficiency, shortens the processing cycle, helps enterprises improve production efficiency, and reduces energy consumption costs.

[0027] 4. A processing technology for super-soft slub velveteen fabric provided by the present invention. Aiming at the problem of difficult cleaning after the fluff on the adhesion plate is saturated, the device optimizes the design of the guide groove and cylinder control. Utilizing the specific inclined and vertical structures of the first and second guide grooves, when the fluff collection on the polytetrafluoroethylene adhesion plate is saturated, the cylinder stroke is adjusted through the controller, keeping the position of the filter mesh unchanged while the pressing plate approaches. At this time, the filter mesh and the adhesion plate are nested with each other, and the fluff on the surface of the adhesion plate is automatically scraped off through mechanical movement, without manual disassembly, with simple and fast operation, effectively reducing the equipment maintenance time and labor costs, and ensuring the stable operation of the dyeing device.

Detailed implementation manners

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a 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 those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figures 1-8 , the present invention provides a technical solution: a processing technology for super-soft bamboo-joint velveteen cloth, including the following steps:

[0039] S1. Inspection: The cloth turning inspection requires manual operation. The inspectors check the appearance of the greige cloth one by one, use a cloth turning machine to turn the greige cloth, and observe whether there are problems such as holes, missing warp, and broken weft to screen qualified greige cloth for subsequent processing;

[0040] S2. Surface treatment: With the help of a raising machine, abrasives such as sand grains or emery on the surface of its abrasive roller come into contact with the fabric, and fine fluff is formed on the cloth surface through mechanical friction;

[0041] S3. Impurity removal: It is carried out in a scouring machine. Under high-temperature alkaline conditions, a scouring agent is added to remove the natural oil stains on the fabric.

[0042] S4. Dyeing: The pretreated fabric is put into a dyeing machine, and water, dyes and auxiliaries are added. During the operation, the pH value and temperature of the dye liquor are monitored and controlled in real time.

[0043] In the S4 dyeing machine of the processing technology of the super soft slub velveteen fabric, there is a dyeing cylinder main body 1. A liquid outlet pipe 2 is connected to the lower part of the dyeing cylinder main body 1. A support roller 3 is rotatably connected to the inner wall of the dyeing cylinder main body 1. A pushing mechanism 4 is arranged inside the dyeing cylinder main body 1, and a sliding mechanism 5 is arranged on one side of the pushing mechanism 4.

[0044] The pushing mechanism 4 includes a cylinder 401 fixedly connected to one side of the dyeing cylinder main body 1. The output end of the cylinder 401 is fixedly connected to a piston rod 402. One side of the piston rod 402 is fixedly connected to a fixing plate 403. A guiding hole 404 is arranged inside the fixing plate 403. A first sliding groove 405 is formed in the inner wall of the dyeing cylinder main body 1. A first sliding block 406 is arranged inside the first sliding groove 405. A first guiding rod 407 fixedly connected to the first sliding block 406 is arranged inside the guiding hole 404. The other end of the first guiding rod 407 is fixedly connected to a pressing plate 408. A controller 409 fixedly connected to the dyeing cylinder main body 1 is arranged below the cylinder 401. The external structure of the guiding hole 404 is an inclined straight line. And two guiding holes 404 are symmetrically arranged about the central axis of the fixing plate 403. And the matching mode of the guiding hole 404 and the first guiding rod 407 is clearance fit. The width of the first sliding groove 405 at the end far from the dyeing cylinder main body 1 is greater than the width of the first sliding groove 405 at the end close to the dyeing cylinder main body 1. And the inner side surface of the first sliding groove 405 is attached to the outer side surface of the first sliding block 406. The central axis of the first sliding groove 405 is perpendicular to the lower surface of the dyeing cylinder main body 1, so that when the fixing plate 403 moves horizontally, it drives the middle of the first guiding rod 407 to move.

[0045] The sliding mechanism 5 includes a first support plate 501 fixedly connected to the dyeing vat main body 1 on one side of the upper pressing plate 408. A first guiding groove 502 is provided inside the first support plate 501. A second sliding groove 503 is provided inside the upper pressing plate 408. A second sliding block 504 is provided inside the second sliding groove 503. A first filter screen 505 is fixedly connected to the lower end of the second sliding block 504. A second guiding rod 506 fixedly connected to the first filter screen 505 is provided inside the first guiding groove 502. First polytetrafluoroethylene adhesion plates 507 are fixedly connected to both sides of the lower surface of the upper pressing plate 408. A second support plate 508 fixedly connected to the dyeing vat main body 1 is provided below the first support plate 501. A second guiding groove 509 is provided inside the second support plate 508. A third sliding groove 510 is provided inside the lower pressing plate 408. A third sliding block 511 is provided inside the third sliding groove 510. The width of the second sliding block 504 and the third sliding block 511 at the end far from the central axis of the dyeing vat main body 1 is greater than the width of the second sliding block 504 and the third sliding block 511 at the end close to the central axis of the dyeing vat main body 1, so that the second sliding block 504 and the third sliding block 511 will not move out of the inner side of the corresponding sliding groove. A second filter screen 512 is fixedly connected to the upper end of the third sliding block 511. A third guiding rod 513 fixedly connected to the second filter screen 512 is provided inside the second guiding groove 509. Second polytetrafluoroethylene adhesion plates 514 are fixedly connected to both sides of the upper surface of the lower pressing plate 408. The first polytetrafluoroethylene adhesion plate 507 closer to the fixing plate 403 is closer to the fixing plate 403 than the second polytetrafluoroethylene adhesion plate 514 closer to the fixing plate 403, and the distance between the two first polytetrafluoroethylene adhesion plates 507 is the same as the distance between the two second polytetrafluoroethylene adhesion plates 514. The outer appearance structure of the lower end of the first guiding groove 502 is a vertical straight line, and the outer appearance structure of the upper end of the first guiding groove 502 is an inclined straight line. The outer appearance structure of the upper end of the second guiding groove 509 is a vertical straight line, and the outer appearance structure of the lower end of the second guiding groove 509 is an inclined straight line. The inclination direction of the upper end of the first guiding groove 502 is the same as the inclination direction of the lower end of the second guiding groove 509, and the vertical straight groove at the lower end of the first guiding groove 502 is closer to the fixing plate 403 than the vertical straight groove at the upper end of the second guiding groove 509.

[0046] When dyeing, wrap the velveteen cloth around the upper part of the support roller 3. Control the cylinder 401 through the controller 409 to drive the air rod 402 to move away from the cylinder 401, driving the fixed plate 403 and the guide hole 404 to move. Since the external structure of the guide hole 404 is an inclined straight line, and two guide holes 404 are symmetrically arranged about the central axis of the fixed plate 403, and the matching mode of the guide hole 404 and the first guide rod 407 is clearance fit. The width of one end of the first chute 405 far from the main body 1 of the dyeing cylinder is greater than the width of one end of the first chute 405 close to the main body 1 of the dyeing cylinder, and the inner side surface of the first chute 405 is attached to the outer side surface of the first slider 406, so that the first guide rod 407 is pushed by the edge of the guide hole 404 to make the first guide rod 407 move towards the middle along the track of the first slider 406 along the first chute 405, driving the pressing plate 408 to move towards the middle. Because the super-soft slub velveteen cloth has slub-shaped textures, the fiber distribution and density of the slub part are different from those of other parts, and it is difficult for the slubs to be dyed well, resulting in different shades of color between the slub and non-slub parts, affecting the dyeing uniformity. Through the pressing plate 408, the dye liquor can better enter the interior of the slubs, making the dyeing more uniform.

[0047] When the pressing plate 408 moves towards the middle, it drives the first filter screen 505 and the second filter screen 512 to move towards the middle, driving the second guide rod 506 and the third guide rod 513 to move towards the middle. Since the lower external structure of the first guide groove 502 is a vertical straight line, and the upper external structure of the first guide groove 502 is an inclined straight line, and the upper external structure of the second guide groove 509 is a vertical straight line, and the lower external structure of the second guide groove 509 is an inclined straight line, the second guide rod 506 and the third guide rod 513 are driven by the first guide groove 502 and the second guide groove 509 to move horizontally along the second chute 503 and the third chute 510, so that the first filter screen 505 and the second filter screen 512 move horizontally, so that the first filter screen 505 and the second filter screen 512 can filter the fluff dropped by the super-soft slub velveteen cloth and move towards the first polytetrafluoroethylene adhesion plate 507 and the second polytetrafluoroethylene adhesion plate 514 on both sides. When the first filter screen 505 and the second filter screen 512 stop, the fluff above the first filter screen 505 and the second filter screen 512 is pushed by the inertial dye liquor to move towards the first polytetrafluoroethylene adhesion plate 507 and the second polytetrafluoroethylene adhesion plate 514, so that the fluff is collected and fixed, reducing the influence of the fluff on the dyeing and improving the quality of the dyeing.

[0048] When the fluff approaches the super soft slub velveteen, there is a chance that it will enter the interior of the super soft slub velveteen again. However, the connection between the fluff and the fabric is not firm, making it easy for the super soft slub velveteen to shed fluff subsequently, affecting the quality of the fabric. During the downward pressing process of the pressing plate 408, the fluff above the first filter screen 505 and the second filter screen 512 adheres to the first polytetrafluoroethylene adhesion plate 507 and the second polytetrafluoroethylene adhesion plate 514, which can reduce the fluff in the dye liquor pushed by the pressing plate 408 and reduce the chance of the fluff approaching the super soft slub velveteen again, thus improving the quality of the fabric.

[0049] Since the chance of the fluff approaching the super soft slub velveteen again is reduced, the blockage of the fiber gaps by impurities is further reduced, enabling the dye liquor to better enter the interior of the fabric and improving the dyeing efficiency.

[0050] Since the inclination direction of the upper end of the first guiding groove 502 is the same as the inclination direction of the lower end of the second guiding groove 509, and the vertical straight groove at the lower end of the first guiding groove 502 is closer to the fixed plate 403 than the vertical straight groove at the upper end of the second guiding groove 509, when the first polytetrafluoroethylene adhesion plate 507 and the second polytetrafluoroethylene adhesion plate 514 are fully adhered, the controller 409 is activated to control the cylinder 401 to move a greater distance, making the upper and lower pressing plates 408 closer, and the horizontal positions of the first filter screen 505 and the second filter screen 512 remain unchanged. Since the first polytetrafluoroethylene adhesion plate 507 on the side closer to the fixed plate 403 is closer to the fixed plate 403 than the second polytetrafluoroethylene adhesion plate 514 on the side closer to the fixed plate 403, and the distance between the two first polytetrafluoroethylene adhesion plates 507 is the same as the distance between the two second polytetrafluoroethylene adhesion plates 514, the first polytetrafluoroethylene adhesion plate 507, the second polytetrafluoroethylene adhesion plate 514, the first filter screen 505, and the second filter screen 512 are nested with each other to scrape off the fluff on the first polytetrafluoroethylene adhesion plate 507 and the second polytetrafluoroethylene adhesion plate 514 on both sides, facilitating cleaning.

[0051] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
