Description

Technical Field

[0001] This invention relates to the field of cashmere fabric production technology, specifically to a production apparatus and method for warp-knitted elastic double-sided cashmere fabric. Background Technology

[0002] Warp-knitted elastic double-sided cashmere fabric, as a high-end textile fabric, is widely used in the fields of clothing, home textiles and industrial textiles due to its excellent warmth retention, soft touch and unique double-sided structure.

[0003] In the production process of warp-knitted elastic double-sided cashmere fabrics, the padding finishing solution (such as softeners, antistatic agents, and other functional auxiliaries) is a crucial step, aiming to impart the desired softness, smoothness, and other properties to the fabric. However, due to the structural characteristics of warp-knitted elastic double-sided cashmere fabrics—to obtain a consistent nap effect on both sides, the fabric structure is usually quite tight and thick. The warp knitting loop structure and the dense pile layer formed after double-sided cutting, as well as the elastic fibers contained in the fabric and their complex interweaving structure with the cashmere yarn, increase the difficulty of liquid transmission in the capillary channels between fibers. As a result, in the conventional padding process, in order to achieve a sufficient penetration effect of the finishing solution into the fabric, it is often necessary to extend the soaking time, which directly leads to a longer production cycle and seriously affects the production efficiency of warp-knitted elastic double-sided cashmere fabrics.

[0004] Therefore, the present invention proposes a production apparatus and method for warp-knitted elastic double-sided cashmere fabric to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a production apparatus and method for warp-knitted elastic double-sided cashmere fabric to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A production apparatus for warp-knitted elastic double-sided cashmere fabric includes a treatment tank for holding a finishing solution. The treatment tank is provided with multiple stretching frames and multiple guide rollers for guiding the fabric to be transported in a meandering manner and sequentially passing through the inner side of the stretching frames. The production apparatus also includes a reciprocating component for driving the multiple stretching frames to move back and forth in a direction perpendicular to the fabric surface, so that the fabric is repeatedly stretched / reset. Multiple vibrating components for vibrating the fabric to promote the penetration of the finishing solution are also staggered on both sides of the fabric transport path on the guide rollers.

[0007] In one alternative embodiment: the reciprocating assembly includes a linkage for fixing multiple tension frames in series, a first slide rail disposed on one side of the processing box, a first slide block slidably engaged in the first slide rail, and a first elastic member disposed in the first slide rail. The linkage is fixedly connected to the first slide block. The reciprocating assembly also includes a turntable rotatably disposed on the processing box and an arc-shaped protrusion for driving the turntable to rotate. Multiple arc-shaped protrusions are evenly distributed circumferentially on the side of the turntable. A rod is provided on the first slide block. The end of the rod away from the first slide block is provided with a first roller that can alternately abut against the side of the multiple arc-shaped protrusions as the turntable rotates.

[0008] In one alternative: the vibrating assembly includes a groove, a slider slidably mounted on the groove, and a vibrating strip mounted on the slider, wherein a second elastic element is provided between the slider and both ends of the groove.

[0009] In one alternative: the position where the stretching frame reciprocates and contacts the fabric is provided with a rolling column.

[0010] In one alternative, the production apparatus further includes a rinsing component for rinsing the soaked fabric to remove adhering lint.

[0011] In one alternative embodiment: the rinsing assembly includes a cylinder housed in a treatment chamber, a sealing piston housed in the cylinder house, and a rinsing channel housed on the cylinder. After the fabric is soaked in liquid, it is conveyed through the rinsing channel. The rinsing channel has cavities on both sides of the fabric conveying path. The side of the cavity facing the fabric conveying path is provided with spray holes. The cylinder house is provided with a liquid extraction port and a liquid outlet. The end of the liquid extraction port is provided with a filter for intercepting floating hair. The liquid outlet is connected to both cavities. The rinsing assembly also includes a driving component for driving the sealing piston to reciprocate to achieve the liquid extraction / discharge action.

[0012] In one alternative: the liquid extraction port is provided with a first one-way valve that only allows the finishing liquid to enter the cylinder, and the liquid outlet is provided with a second one-way valve that only allows the finishing liquid in the cylinder to be discharged.

[0013] In one alternative embodiment: the driving component includes a second slide rail located on one side of the processing box and a second slide block slidably engaged in the second slide rail. The sealing piston is provided with a driven rod, which slides through the cylinder wall in a sealed manner, and the end of the driven rod away from the sealing piston is connected to the second slide block. The second slide block is provided with a second roller that can alternately abut against the sides of multiple arc-shaped protrusions as the turntable rotates. The cylinder is provided with a plurality of mounting parts, and a slide rod is slidably passed through the mounting parts. One end of the slide rod is connected to the sealing piston, and a third elastic element is sleeved on the rod segment of the slide rod located between the sealing piston and the mounting parts.

[0014] A method for producing warp-knitted elastic double-sided cashmere fabric, using any of the above-described production apparatuses for warp-knitted elastic double-sided cashmere fabric, includes the following steps: S1: Inject an appropriate amount of finishing liquid into the processing box. The warp-knitted elastic double-sided cashmere fabric is transported at a constant speed in a meandering manner under the action of multiple guide rollers and passes through the inside of the stretching frame in sequence. S2: The reciprocating components drive multiple stretching frames to move back and forth perpendicular to the fabric surface, causing the fabric to be repeatedly stretched / reset. The fabric tension and relaxation cycle promotes the penetration of the finishing liquid. Combined with the vibration component, the fabric is vibrated, allowing the finishing liquid to penetrate the fabric.

[0015] Compared with the prior art, the beneficial effects of the embodiments of the present invention are as follows: The reciprocating components drive multiple stretching frames to move back and forth perpendicular to the fabric surface, causing the fabric to be repeatedly stretched and reset. When the fabric is stretched, the gaps between fibers and yarns increase, which facilitates the penetration of the finishing solution. When the fabric shrinks and resets, it squeezes the gaps between fibers and yarns, which further promotes the penetration of the finishing solution. The fabric tension and relaxation cycle promotes the penetration of the finishing solution. Combined with the vibration component to vibrate the fabric, the finishing solution can penetrate the fabric quickly, efficiently and evenly, effectively shortening the time required for the fabric to be soaked in the solution and improving the production efficiency of warp-knitted elastic double-sided cashmere fabric.

Detailed Implementation

[0025] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0026] Please see Figure 1 A production apparatus for warp-knitted elastic double-sided cashmere fabric includes a treatment tank 2 for holding finishing liquid. The treatment tank 2 is provided with multiple stretching frames 4 and multiple guide rollers 3 for guiding the fabric to be transported in a meandering manner and sequentially passing through the inner side of the stretching frames 4. The production apparatus also includes a reciprocating component 9 for driving the multiple stretching frames 4 to move back and forth in a direction perpendicular to the fabric surface so that the fabric is repeatedly stretched / reset. Multiple vibrating components 7 for vibrating the fabric to promote the penetration of finishing liquid are also staggered on both sides of the fabric transport path on the guide rollers 3.

[0027] First, an appropriate amount of finishing liquid is injected into the treatment tank 2. Then, the warp-knitted elastic double-sided cashmere fabric (hereinafter referred to as the fabric) is conveyed at a constant speed in a meandering manner under the action of multiple guide rollers 3 and passes sequentially through the inner side of the stretching frame 4 (during this process, the corresponding fabric segments are immersed in the finishing liquid). The reciprocating component 9 drives the multiple stretching frames 4 to move back and forth perpendicular to the fabric surface, so that the fabric is repeatedly stretched / reset (the degree of stretching is within the allowable range of elastic deformation of the fabric, and there will be no damage to the fabric structure due to excessive stretching). When the fabric is stretched, the gap between the fibers and yarns increases, which facilitates the penetration of the finishing liquid (the expansion of the micro-pore structure of the fabric reduces the penetration resistance of the finishing liquid in the fiber capillary network, and greatly improves the wetting rate and penetration efficiency of the finishing liquid). When the fabric shrinks and resets, it exerts a squeezing effect on the gaps between fibers and yarns, which in turn promotes the penetration of the finishing solution (the shrinkage of the pores in the fabric creates a squeezing effect, driving the finishing solution into the finer gaps for deep penetration). The fabric tension and relaxation cycle further promotes the penetration of the finishing solution (during the reciprocating movement of the tension frame 4, the fabric and the finishing solution also move in the direction perpendicular to the fabric surface, forming a movement where the fabric surface meets the movement of the finishing solution, using the fluid flow impact effect to promote the penetration of the finishing solution into the fabric). Combined with the vibration component 7 to vibrate the fabric, the finishing solution penetrates the fabric quickly, efficiently, and uniformly, effectively shortening the time required for the fabric to be soaked in the solution and improving the production efficiency of warp-knitted elastic double-sided cashmere fabric.

[0028] Furthermore, the position where the stretching frame 4 reciprocates and contacts the fabric is provided with a rolling column 8. By setting the rolling column 8 to have a curved protective contact with the fabric, damage to the fabric is avoided.

[0029] Please see Figures 1-4 In one embodiment of the present invention, the reciprocating assembly 9 includes a linkage 901 for fixing multiple stretch frames 4 in series, a first slide rail 903 disposed on one side of the processing box 2, a first slide block 902 slidably locked in the first slide rail 903, and a first elastic element 904 (preferably, the first elastic element 904 is a spring) disposed in the first slide rail 903. The linkage 901 is fixedly connected to the first slide block 902. The reciprocating assembly 9 also includes a turntable 907 rotatably disposed on the processing box 2 and a driving element 909 for driving the turntable 907 to rotate (the driving element 909 is a servo motor, geared motor, etc. in the prior art). The turntable 907 is provided with multiple arc-shaped protrusions 908 evenly distributed on its side circumferentially. The first slide block 902 is provided with a rod 905. The end of the rod 905 away from the first slide block 902 is provided with a first roller 906 that can alternately abut against the side of the multiple arc-shaped protrusions 908 as the turntable 907 rotates.

[0030] In this embodiment, the turntable 907 is driven to rotate by the drive component 909, which in turn causes multiple arc-shaped protrusions 908 to revolve and alternately abut against the first roller 906. During the stroke of the first roller 906 in contact with the arc-shaped protrusions 908, the first slide block 902 is pushed to slide away from the turntable 907, which causes multiple stretching frames 4 to move and stretch the fabric. At the same time, the first elastic element 904 is compressed. When the first roller 906 disengages from the arc-shaped protrusions 908, the first slide block 902 resets under the action of the first elastic element 904, which causes multiple stretching frames 4 to reset and the fabric to retract and reset. This cycle is repeated to realize the reciprocating movement of multiple stretching frames 4. It should be noted that the first slide block 902 and the side wall of the treatment box 2 are provided with corresponding sealing measures, such as a sealing telescopic sleeve, elastic film, etc. (which do not affect the sliding function of the first slide block 902), to seal the side of the first slide rail 903 that is connected to the inside of the treatment box 2 to prevent the finishing liquid from flowing out. This is prior art and will not be described in detail here.

[0031] Based on the previous embodiment, please refer to Figure 5 In one embodiment of the present invention, the vibrating assembly 7 includes a slide groove 701, a slider 702 slidably mounted on the slide groove 701, and a vibrating strip 704 mounted on the slider 702. A second elastic element 703 (preferably, the second elastic element 703 is a spring) is provided between both ends of the slider 702 and the slide groove 701.

[0032] In this embodiment, when the first roller 906 disengages from the arc-shaped protrusion 908, the first slide block 902 resets under the action of the first elastic element 904. This reset action produces a momentary pause when the first slide block 902 is reset in place (i.e., the first slide block 902 contacts the end of the first slide rail 903 near the turntable 907), causing the slider 702 to vibrate under the action of the two second elastic elements 703, that is, driving the vibrating strip 704 to vibrate, thereby vibrating the fabric and further promoting the penetration of the finishing liquid.

[0033] Please see Figure 1 , Figure 2 , Figure 4 and Figure 6 In one embodiment of the present invention, the production apparatus further includes a rinsing component 5 for rinsing the fabric after soaking to remove adhering lint from the fabric. The rinsing assembly 5 includes a cylinder 501 in the processing tank 2, a sealing piston 506 in the cylinder 501, and a rinsing channel 503 on the cylinder 501. After the fabric is soaked in liquid, it is transported through the rinsing channel 503. The rinsing channel 503 has cavities 504 on both sides of the fabric transport path (the liquid level is lower than the lower edge of the cavity 504). The side of the cavity 504 facing the fabric transport path is provided with spray holes 505. The cylinder 501 is provided with a liquid extraction port 509 and a liquid outlet 513. The end of the liquid extraction port 509 is provided with a filter 511 for intercepting floating hair. The liquid outlet 513 is connected to both cavities 504 (through pipes). The rinsing assembly 5 also includes a driving component for driving the sealing piston 506 to reciprocate to achieve the liquid extraction / discharge action. The liquid extraction port 509 is provided with a first one-way valve 510 that only allows the finishing liquid to enter the cylinder 501, and the liquid outlet 513 is provided with a second one-way valve 514 that only allows the finishing liquid in the cylinder 501 to be discharged. The driving component includes a second slide rail 515 located on one side of the processing box 2 and a second slide block 516 slidably engaged in the second slide rail 515. A driven rod 512 is provided on the sealing piston 506. The driven rod 512 slidably penetrates the wall of the cylinder 501 in a sealed manner, and one end of the driven rod 512 away from the sealing piston 506 is connected to the second slide block 516. The second slide block 516 is provided with second rollers 517 that can alternately abut against the sides of multiple arc-shaped protrusions 908 as the turntable 907 rotates. Several mounting parts 502 are provided on the cylinder 501, and the mounting parts 502 slidably penetrate... A slide rod 507 is provided, and one end of the slide rod 507 is connected to the sealing piston 506. A third elastic element 508 (preferably, the third elastic element 508 is a spring) is sleeved on the rod section of the slide rod 507 located between the sealing piston 506 and the mounting part 502. It should be noted that the second slide seat 516 and the side wall of the processing box 2 are also provided with corresponding sealing measures, such as a sealing telescopic sleeve, elastic film, etc. (which do not affect the sliding function of the second slide seat 516), to seal the side of the second slide rail 515 that is connected to the inside of the processing box 2 to prevent the finishing liquid from flowing out. This is the prior art and will not be described in detail here.

[0034] In this embodiment, since the warp-knitted elastic double-sided cashmere fabric experiences some shedding of loose fibers during the soaking process, to prevent these fibers from adhering to the fabric and requiring additional cleaning steps, a rinsing assembly 5 is provided to rinse the loose fibers adhering to the fabric. Specifically, the turntable 907 rotates, causing multiple arc-shaped protrusions 908 to revolve and alternately contact the second roller 517. During the stroke of the second roller 517 in contact with the arc-shaped protrusions 908, the driven rod 512 is moved upward (towards...). Figure 3 , Figure 6(Explained from the angle shown) That is, the sealing piston 506 is driven to move upward, thereby drawing the finishing liquid into the cylinder 501 and compressing several third elastic elements 508 at the same time. The finishing liquid entering the cylinder 501 is filtered by the filter 511 to intercept the floating hair, and is a clean finishing liquid. When the second roller 517 disengages from the arc-shaped protrusion 908, the sealing piston 506 moves downward and resets under the action of several third elastic elements 508, and sends the clean finishing liquid in the cylinder 1 to the two cavities 504 and sprays it out through the spray hole 505 to rinse the fabric. This cycle is repeated to achieve the effect of rinsing the fabric and cleaning the floating hair.

[0035] Furthermore, in this embodiment, the rinsing channel 503 is provided with a pressing roller 6 for pressing the rinsed fabric above the cavity 504.

[0036] The present invention also provides a method for producing warp-knitted elastic double-sided cashmere fabric, using any of the above-described production apparatuses for warp-knitted elastic double-sided cashmere fabric, comprising the following steps: S1: Inject an appropriate amount of finishing liquid into the processing box 2. The warp-knitted elastic double-sided cashmere fabric is transported at a constant speed in a meandering manner under the action of multiple guide rollers 3 and passes through the inner side of the stretching frame 4 in sequence. S2: The reciprocating component 9 drives multiple stretching frames 4 to move back and forth perpendicular to the fabric surface, causing the fabric to be repeatedly stretched / reset. The fabric tension and relaxation cycle promotes the penetration of the finishing liquid. Combined with the vibration component 7, the fabric is vibrated, allowing the finishing liquid to penetrate the fabric.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
