Description

Technical Field

[0001] The invention belongs to the technical field of textile dyeing, and in particular relates to a yarn zero-color difference star cage dyeing device and a dyeing process using the same. Background Art

[0002] Yarn-dyed fabrics are comfortable to wear, and have the advantages of moisture absorption, moisture retention, heat resistance, alkali resistance, hygiene, and beauty. They are the first choice for formal clothing. Yarn-dyed fabrics are made by first dyeing the yarn in cheese, and then passing the dyed yarn through a loom. The warp and weft yarns are interwoven vertically and horizontally to form a textile with rich colors and varied patterns.

[0003] Traditional cheese dyeing is to wind the yarn on the resin bobbin, and then install the cheeses one by one on the creel rod (vertical tube with holes) for dyeing. Traditional cheese dyeing has always had the problem of color difference between the outer and middle layers, and the outer and inner layers of the dyed cheese, which seriously affects the quality of yarn dyeing and further affects the quality of yarn-dyed fabrics. In addition, cheese dyeing has particularly high requirements for resin bobbins. In order to avoid staining, resin bobbins of different colors cannot be mixed, so the consumption of resin bobbins is very large and the cost is very high. This has always been a problem that has plagued the textile industry.

[0004] In the prior art, the loose-winded bobbins are stacked one by one on vertical perforated tubes. There are usually several vertical perforated tubes in one pot. The working liquid or dye liquid is divided into several strands and sprayed out from different perforated tubes, which usually leads to uneven working liquid or dye liquid. The colors of the bobbins on different vertical perforated tubes will have more or less color difference. There are gaps between the upper and lower adjacent bobbins, because the winding of the yarn on the resin bobbin cannot achieve the full coverage of the yarn on the resin bobbin at both ends near the edge, and the gaps between the upper and lower adjacent bobbins will cause dye liquid flow loss, that is, the dye liquid or working liquid after a cycle does not contact the yarn completely, and flows out into the next cycle, resulting in a waste of resources and energy, while reducing production efficiency.

[0005] Patent CN102277698A discloses a new process for dyeing polyester air-change yarn. The invention relates to the field of textile printing and dyeing technology, and provides a method for dyeing, which can fully penetrate the inner and outer yarns of the cheese yarn, that is, the cheese yarn is first subjected to two loose winding and steaming methods before dyeing, so as to fully ensure the elasticity of the polyester air-change yarn by physical methods, and reduce the color difference between the inner and outer layers of the dyed cheese yarn. The new process includes a loose winding process, a steaming and shaping process, a loose winding process, a dyeing process, a finishing process, and a dehydration and drying process. This patent reduces the internal and external color difference of dyeing caused by the shrinkage of polyester during dyeing by steam pre-shrinking the polyester in advance. Although it can reduce the internal and external color difference of yarn dyeing compared with the traditional cheese yarn dyeing method, it still uses the cheese yarn dyeing method. The existence of the resin cheese can never completely solve the problem of internal and external color difference of yarn dyeing, and it increases the cost.

[0006] Patent CN108611881A discloses a method for preparing a cellulose fiber white dyed fabric. This patent introduces a dyeing process for modified cellulose fiber / unmodified cellulose fiber, and the process operation is simple and easy. However, this process is a process for fabrics, and the reducing agent used in this process will remove part of the color, affecting the color stability. It is not suitable for the color weaving process of dyeing the yarn first and then weaving the cloth.

[0007] Patent CN107964812A discloses a modified cellulose fiber dyeing process, which uses a tea saponin pretreatment scouring process. This process can reduce energy consumption, but the tea saponin scouring effect is relatively mild, and some impurities will remain, which will reduce the color brightness.

[0008] Patent CN104358161A discloses a salt-free and low-alkali modified dyeing process for cellulose fibers. This patent introduces a salt-free and low-alkali modified dyeing process for cellulose fibers, focusing on the effect of the modification process of cellulose fibers on dyeing. The salt-free and low-alkali dyeing process adopted by it can reduce the salt and alkali content in the dyeing wastewater and reduce the treatment pressure of the dyeing wastewater. However, this method does not perform pre-dyeing treatment, is not suitable for dyeing partially modified yarns, will reduce the depth and color brightness of the color, and is not suitable for the requirement of no color difference in cheese dyeing.

[0009] Patent CN108660653A discloses a yarn processing and dyeing device, including a base, wherein a drying barrel and a dyeing barrel are symmetrically arranged at the upper end of the base, and a drying chamber and a dyeing chamber opening upward are respectively arranged in the drying barrel and the dyeing barrel, and a heating plate is arranged on the side wall of the drying barrel, and a heating chamber is arranged in the heating plate. The invention realizes the process of yarn dyeing and drying by performing dyeing and drying in the yarn processing process simultaneously, and the dyed yarn raw material can be dried subsequently, thereby reducing the waste of processing time and improving work efficiency. The driving device drives the plug rod on the cross bar to rotate, so that the sleeve with yarn wound on the plug rod in the drying chamber and the dyeing chamber rotates, so that all sides of the yarn in the drying chamber can be blown by hot air, which speeds up drying, reduces drying time, and improves work efficiency. The sleeve in the dyeing chamber rotates in the dye, so that it is dyed more fully, improves the dyeing effect, and improves the dyeing efficiency. However, the device still cannot get rid of the use of the sleeve, and even if the improvement of its dyeing effect is achieved by rotating the heating lamp, it is still very limited. Summary of the invention

[0010] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a yarn zero color difference star cage dyeing device, which breaks the current status of cheese yarn dyeing production equipment, realizes bobbin-free and tension-free yarn bundle dyeing, and achieves zero color difference yarn dyeing effect through dye liquid circulation.

[0014] The yarn bundle grate is provided with a lifting ring.

[0015] The zero-color-difference star cage dyeing device for yarn also includes a cross lifting chain. The cross lifting chain includes a cross bar. A number of diameter adjusting rings are arranged below the cross bar. A ring-shaped lifting structure is arranged at the central position of the cross bar. It also includes a suspension chain. Disassembly buckles are arranged at both ends of the suspension chain.

[0016] It is possible to select to buckle the suspension chain on the diameter adjusting rings at different positions according to the diameter specification of the yarn bundle grate, so as to adapt to yarn bundle grates of multiple specifications.

[0017] The pressing and sealing device successively includes a yarn bundle pressing cover, a blind tube, a cap cover, and a locking nut from bottom to top; A sealing gasket is arranged between the star cage yarn bundle seat and the yarn bundle grate. The sealing gasket forms a seal with the yarn bundle grate to prevent the loss of the flow rate of the dyeing solution. The circulating pipeline is connected to the drain pipe. A valve is arranged on the drain pipe. When it is necessary to discharge the working fluid or the dyeing solution, the valve is automatically controlled to discharge.

[0018] The dyeing process using the zero-color-difference star cage dyeing device for yarn according to the present invention includes the following process steps: 1) Loose winding: The yarn is evenly wound into a non-tension yarn bundle through the integral chuck bobbin of a loose winding machine; 2) Yarn bundle loading: The yarn bundle grate is horizontally lifted by a lifting device. Further, the lifting device suspends the ring-shaped lifting structure of the cross lifting chain, and the disassembly buckle below the suspension chain hooks the lifting ring of the yarn bundle grate to horizontally lift the yarn bundle grate. The non-tension yarn bundle wrapped with a stocking tube is layer by layer placed around the center in a ring shape on the yarn bundle grate. The placement method of the non-tension yarn bundle is staggered in both the horizontal and vertical directions, that is, in a "pin" shape; 3) Assembly of the zero-color-difference star cage dyeing device for yarn: The sealing gasket is passed through the star tube and pressed onto the star cage yarn bundle seat. Then, the loaded yarn bundle grate is passed through the star tube and placed on the sealing gasket. The yarn bundle pressing cover is passed through the star tube and pressed on the placed non-tension yarn bundle. Then, according to the loading height of the non-tension yarn bundle, the length of the blind tube is selected and pressed on the yarn bundle pressing cover. The cap cover, the locking nut, and the lifting nut are successively fixedly connected to the central rod by threads. The lifting device hooks the lifting nut to place the assembled device in the main cylinder of the dyeing machine. The star cage yarn bundle seat is closely matched with the circulating pipeline at the bottom of the main cylinder of the dyeing machine, without flow rate loss; 4) Pretreatment + dyeing process or pretreatment whitening one-bath process: Pretreatment + dyeing process: The working liquid circulation method is used for treatment: the circulation pump is started, and the scouring and bleaching working liquid is pumped into the star tube from the circulation pipeline. The working liquid fully contacts the tension-free yarn bundle placed in the star cage from the inside to the outside through the overflow hole on the star tube, and then overflows into the main cylinder of the dyeing machine through the overflow hole on the star cage. The working liquid is pumped into the star tube again through the liquid outlet pipe via the circulation pump, and the treatment is repeated. After the pretreatment scouring and bleaching process is completed, the scouring and bleaching working liquid is drained through the drainage pipe, and water, dyes, and auxiliaries are added to obtain the dye solution. The dye solution is also sprayed from the star tube from the inside to the outside using the circulation pump, and overflows from the star cage through the tension-free yarn bundle to the main cylinder of the dyeing machine and then circulates repeatedly; Pre-treatment whitening one-bath process: the working liquid circulation method is used for treatment: the circulation pump is started, and the scouring, bleaching and whitening working liquid is pumped into the star tube from the circulation pipeline, and the working liquid is fully contacted with the tension-free yarn bundle placed in the star cage from the inside to the outside through the overflow hole on the star tube, and then overflows into the main cylinder of the dyeing machine through the overflow hole on the star cage, and is pumped into the star tube again through the liquid outlet pipe via the circulation pump, and the treatment is repeated for reciprocating. After the treatment is completed, the scouring, bleaching and whitening working liquid is completely discharged through the drain pipe; 5) Post-treatment: washing → (soap washing → color fixing) → softening steps, using working liquid circulation method for treatment; whitening and light color dyeing processes do not require soap washing and color fixing steps; 6) Dehydration and drying: The tension-free yarn bundle is dehydrated by a centrifugal dehydrator and then dried; 7) Tight winding: After being evenly supported by the telescopic yarn support frame, the tension-free yarn bundle after drying is installed on the active unwinding bobbin shaft of the active unwinding automatic winder for tight winding.

[0019] The tension-free yarn bundles described in step 1) weigh 0.5-2 kg each.

[0020] In the pretreatment + dyeing process described in step 4), the scouring and bleaching working solution is 2-4 g / L of refining agent, 2-4 g / L of caustic soda, and 4-8 g / L of hydrogen peroxide, the pretreatment temperature is 100-110°C, and the insulation time is 30-60min; the dyeing process adopts the method of immersion dyeing, the added salt is 10-80g / L, and the dye is evenly added to the main cylinder of the dyeing machine at 40-50°C within 10-30min, the dye concentration is 0.1%-8% of the total weight of the tension-free yarn bundle, the power of the circulating pump is 80-95% of the rated power, when the loading rate of the dyeing machine (the loading rate of the improved device can be higher than the factory setting loading rate, can exceed 100%, and the loading rate is the weight loading rate) is 100%, the power of the circulating pump is 85% of the rated power, and the loading rate is ±10%, and the power of the circulating pump is ±5%.

[0021] The dye liquor circulation direction is non-reversing to ensure that the yarn bundle is in full contact with the dye liquor. The temperature is kept for 20-45 minutes, then the temperature is raised to 60-90°C, soda ash is added, the soda ash concentration is 5-20 g / L, and the color is fixed for 40-60 minutes.

[0022] The dye liquor circulation direction is non-reversing to ensure that the yarn bundle is fully in contact with the dye liquor, the temperature is raised to 60-90°C at 1°C / min, kept warm for 20-45min, and fixed for 40-60min.

[0023] In the one-bath pretreatment whitening process described in step 4), the working liquid for scouring, bleaching and whitening is 2-4 g / L of refining agent, 2-4 g / L of caustic soda, 4-8 g / L of hydrogen peroxide, and 0.4-0.7% of whitening agent (total weight of tension-free yarn bundle), the temperature is 100-110 °C, the holding time is 30-60 min, the power of the circulating pump is 80-95% of the rated power, when the loading rate of the dyeing machine (the loading rate of the improved device can be higher than the loading rate set by the factory, and can exceed 100%, and the loading rate is the weight loading rate) is 100%, the power of the circulating pump is 85% of the rated power, and the power of the circulating pump is ±5% for every ±10% of the loading rate. The working liquid circulation direction adopts a non-reversing method to ensure that the yarn bundle is fully in contact with the dye solution.

[0024] The yarn described in step 1) is cellulose fiber, regenerated fiber, synthetic fiber and their blends and core-spun; the entire processing process is carried out in a bobbin-free and tension-free state.

[0025] Step 5) The soaping is performed by soaping with a soaping agent in an amount of 1-2 g / L, the temperature is controlled at 95-105°C, and the heat preservation time is 10-15 min. After soaping, the floating color is washed off with water for 5-10 min. The dark varieties are fixed with a cationic color fixing agent of 2-4%, and 3-5% softener by weight of the tension-free yarn bundle is added to the same bath for color fixing and softening. The process is 55±1°C for 20 min. The light-colored or white varieties are only softened, and 3-5% softener by weight of the tension-free yarn bundle is added. The process is 55±1°C for 20 min.

[0026] The use of the yarn zero color difference star cage dyeing device first requires changing the shape of the yarn. In the prior art, the loose winding winds the yarn on a resin bobbin. The yarn shape used in the yarn zero color difference star cage dyeing device described in the present invention is a tension-free yarn bundle, that is, the yarn is completely separated from the resin bobbin. In order to achieve this yarn bundle shape, the chuck and the resin bobbin on the loose winding machine are modified. In the prior art, the chuck is fixed on the loose winding machine, and the resin bobbin and the chuck are detachably connected. After the loose winding is completed, the resin bobbin and the yarn wound on the resin bobbin are removed together and transported to the dyeing machine for dyeing. After the modification, an integrated chuck bobbin is used.

[0027] Step 1) The one-piece chuck tube includes an outer tube and an inner fixed tube, the outer tube has a smooth surface, and the one-piece chuck tube is divided into a front end and a rear end, an annular sock groove is opened between the inner fixed tube and the outer tube at the rear end; a plurality of arc grooves are opened between the sock groove and the outer tube; a plurality of trapezoidal grooves are opened between the inner fixed tube and the outer tube at the front end.

[0028] The opening of the arc groove and the trapezoidal groove helps to reduce the weight of the one-piece chuck bobbin and increase the spinning speed. Before use, the one-piece chuck bobbin is covered with a tubular knitted sock tube with unsealed ends. Because the inner fixed tube of the one-piece chuck bobbin is installed on the bobbin shaft of the loose automatic bobbin winding machine, the rear end is close to the bottom of the bobbin shaft, one end of the sock tube is inserted into the annular plug sock groove for fixing, and the other end of the sock tube is inserted into the inner fixed tube at the front end, and then the inner fixed tube is plugged with a sock tube fixing plug. The sock tube fixing plug is a truncated cone-shaped hollow plug, the diameter of the small diameter end of the cone is smaller than the diameter of the inner fixed tube, and the large diameter end of the cone is larger than the diameter of the inner fixed tube, so as to ensure that the sock tube is plugged and fixed at the front end of the one-piece chuck bobbin. During the process of winding the yarn through the loose winding machine, the yarn is wound to the outside of the sock. After winding, the two ends of the sock are picked up and held in the middle, and then the yarn wrapped by the sock is pulled off from the integrated chuck bobbin to obtain the tension-free yarn bundle wrapped by the sock. Using the sock to cover the tension-free yarn bundle can prevent the tension-free yarn bundle from being dispersed by the working liquid or dye liquid in the yarn zero color difference star cage dyeing device.

[0029] Step 7) The telescopic yarn support frame includes a main rod, a hollow cavity is provided in the center of the main rod, a front fixed head and a rear fixed head are provided at both ends of the main rod, a spring is provided inside the front fixed head, and the bottom of the spring is abutted against the annular sleeve, an adjustment hole is provided on the main rod, an adjustment slider is provided above the adjustment hole, a strip sliding hole is provided on the adjusting slider, a locking bolt passes through the strip sliding hole and the adjustment hole to fix the adjusting slider on the main rod, one end of the adjusting slider is abutted against the annular sleeve, the telescopic yarn support frame also includes a plurality of tension bars telescopically connected to the main rod, the rear fixed head is connected to the tension bar through a fixed bracket, the fixed bracket is connected to the rear fixed head and the tension bar in a hinged manner, the annular sleeve is connected to the tension bar through a movable bracket, the movable bracket is hinged to the annular sleeve, a slide groove is provided on the tension bar, and the movable bracket is connected to the tension bar through an adjustment shaft passing through the slide groove.

[0030] The spring is fixed inside the front fixing head through a fixing pin.

[0031] The tension strip is provided with a plurality of anti-slip protrusions.

[0032] The bottom of the adjusting slider is an arc surface, which fits tightly with the main rod. This design can prevent the adjusting slider from swinging left and right or rotating, so that the adjusting slider can only move up and down along the axis, so that it can better resist the annular sleeve and the structure is more stable.

[0033] The tension bar is close to the rear fixed head end and expands radially outward away from the main rod direction, and the tension bar is close to the front fixed head end and converges radially inward toward the main rod direction.

[0034] The tension-free yarn bundle is inserted into the outside of the tension bar from the front fixed head end, and the inward convergent end plays a guiding role, making it easier for the tension-free yarn bundle to be inserted into the outside of the tension bar with tension. Through the position setting of the spring, the annular sleeve and the adjusting slider, the appropriate position is selected according to the different yarn bundle diameters. The spring applies an outward tension so that the tension-free yarn bundle can always maintain a tight state on the tension bar, so that the active unwinding process can be completed smoothly. As the active unwinding process proceeds, the yarn on the tension bar becomes less and less, and the inward pressure becomes smaller and smaller. The spring can continue to apply pressure outward to keep the yarn bundle in a taut state at all times.

[0035] The hollow cavity of the main rod of the telescopic yarn support frame is inserted into the active unwinding bobbin shaft of the active unwinding automatic winder. Preferably, it is further fixed in the front with a fixed clamp to prevent it from falling off during the unwinding rotation process. During the unwinding process, the telescopic yarn support frame rotates with the active unwinding bobbin shaft, and the yarn is easily slipped outward due to the axial force of the rotation of the active unwinding bobbin shaft. The anti-slip protrusion and the outward expansion end of the tension bar can work together to prevent the yarn from slipping and falling off.

[0036] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention breaks the conventional thinking of dyeing cheese yarn in the industry and adopts the dyeing of tension-free yarn bundles without bobbins, which solves the problem that the resin bobbins in the prior art have no elasticity and the yarns tightly wound on the resin bobbins are difficult to penetrate evenly during dyeing, which easily leads to color difference between the inner and outer layers and uneven dyeing. At the same time, the resin bobbins are omitted, and there is no need to carry the resin bobbins during the dyeing process, which saves manpower and material resources.

[0037] (2) In the prior art, the resin tube will be stained by different dyes. The stained resin tube cannot be used for dyeing cheese yarns of other colors, which narrows the scope of application. The present invention adopts tube-free dyeing to produce any color according to the color requirements, which broadens the scope of application of the color spectrum.

[0038] (3) The tension-free yarn bundle is processed by spraying working liquid or dyeing liquid outwardly through the central star tube in the yarn zero color difference star cage dyeing device. Compared with the prior art in which the working liquid or dyeing liquid is sprayed outwardly through the perforated pipeline in the center of the resin bobbin of the package yarn stacked in several piles, the working liquid or dyeing liquid concentrated on one star tube is sprayed outwardly more evenly than being sprayed out from several different pipelines, which further solves the problem of color difference between package yarns in the prior art.

[0039] (4)In the present invention, the tension-free yarn bundles in the star shroud are arranged in a "pin" shape, intertwined and surrounded. From top to bottom and from inside to outside, there are no radial gaps, so there will be no loss of the flow rate of the working fluid or dye liquor. The working fluid or dye liquor ejected from the star tube must come into contact with the yarn and penetrate before re-entering the circulation, greatly improving the production efficiency.

[0040] (5)In the dyeing process described in the present invention, the adjustment and control of various process parameters during the dyeing process enable the dyed yarn bundles to have no color difference between the inner and outer layers; reduce the generation of waste yarn, thereby reducing the dyeing cost.

[0041] (6)In the dyeing process described in the present invention, the color penetration is good, the color brightness and the yarn fastness are relatively good, and it can be applied to various style yarn-dyed fabrics.

[0042] (7)Since the present invention dyes tension-free yarn bundles, unlike tightly structured cheese yarns, using a low circulation flow rate for dyeing can achieve uniform dyeing. At the same time, low-flow dyeing can also reduce the loss of yarn strength and save energy costs.

[0043] (8)The present invention uses tube-free dyeing. In a dyeing machine of the same model, it can hold more yarn bundles, enabling large-batch dyeing of yarn bundles, improving the production efficiency. And not using resin tubes greatly reduces the production cost. Without the need to handle the cheese, the production process becomes more flexible and fast. Description of the Drawings

[0058] The circulation pipeline 4 is connected to the drain pipe 39. The drain pipe 39 is provided with a valve, and when the working liquid or dye liquid needs to be discharged, the valve is automatically controlled to discharge.

[0059] The one-piece chuck barrel 33: Figure 7-12 As shown, it includes an outer tube 40 and an inner fixed tube 35, the outer tube 40 has a smooth surface, and the integrated chuck tube 33 is divided into a front end and a rear end, and an annular sock plugging groove 34 is provided between the inner fixed tube 35 and the outer tube 40 at the rear end; a plurality of arc grooves 36 are provided between the sock plugging groove 34 and the outer tube 40; a plurality of trapezoidal grooves 37 are provided between the inner fixed tube 35 and the outer tube 40 at the front end.

[0060] The arc groove 36 and the trapezoidal groove 37 are provided to reduce the weight of the integrated chuck bobbin 33 and increase the spinning speed. Before use, the integrated chuck bobbin 33 is covered with a tubular knitted sock tube with unsealed ends. Since the inner fixed tube 35 of the integrated chuck bobbin 33 is installed on the bobbin shaft of the loose automatic bobbin winding machine, the rear end is close to the bottom of the bobbin shaft, one end of the sock tube is inserted into the annular plug sock groove 34 for fixing, and the other end of the sock tube is inserted into the inner fixed tube 35 at the front end, and then the inner fixed tube 35 is plugged with a sock tube fixing plug 38. The sock tube fixing plug 38 is a truncated cone-shaped hollow plug, the diameter of the small diameter end of the truncated cone is smaller than the diameter of the inner fixed tube 35, and the large diameter end of the truncated cone is larger than the diameter of the inner fixed tube 35, so as to ensure that the sock tube is plugged and fixed at the front end of the integrated chuck bobbin 33. During the process of winding the yarn through the loose winding machine, the yarn is wound to the outside of the sock tube. After winding, the two ends of the sock tube are picked up and folded toward the middle, and then the yarn wrapped by the sock tube is pulled off from the integrated clamping head tube 33 to obtain the tension-free yarn bundle wrapped by the sock tube. Using the sock tube to cover the tension-free yarn bundle can prevent the tension-free yarn bundle from being dispersed by the working liquid or dyeing liquid in the yarn zero color difference star cage dyeing device.

[0061] The telescopic yarn support frame: Figure 13-15 As shown, it includes a main rod 19, a hollow cavity 30 is provided in the center of the main rod 19, a front fixing head 31 and a rear fixing head 32 are provided at both ends of the main rod 19, a spring 23 is provided inside the front fixing head 31, and the bottom of the spring 23 abuts against the annular sliding sleeve 25, an adjustment hole 28 is provided on the main rod 19, an adjustment slider 26 is provided above the adjustment hole 28, a strip sliding hole 2601 is provided on the adjustment slider 26, a locking bolt 27 passes through the strip sliding hole 2601 and the adjustment hole 28 to fix the adjustment slider 26 on the main rod 19, and the adjustment slider 26 is fixed to the main rod 19. One end is in contact with the annular sleeve 25, and the telescopic yarn support frame also includes four tension bars 20 telescopically connected to the main rod 19. The rear fixed head 32 is connected to the tension bar 20 through a fixed bracket 21, and the fixed bracket 21 is connected to the rear fixed head 32 and the tension bar 20 in a hinged manner. The annular sleeve 25 is connected to the tension bar 20 through a movable bracket 22, and the movable bracket 22 is hinged to the annular sleeve 25. A slide groove 29 is provided on the tension bar 20, and the movable bracket 22 is connected to the tension bar 20 through an adjusting shaft passed through the slide groove 29.

[0062] The spring 23 is fixed inside the front fixing head 31 via a fixing pin 24 .

[0063] The tension strip 20 is provided with a plurality of anti-slip protrusions 2001 .

[0064] The bottom of the adjusting slider 26 is an arc surface, which fits tightly with the main rod 19. This design can prevent the adjusting slider 26 from swinging left and right or rotating, so that the adjusting slider 26 can only move up and down along the axial direction, so that it can better resist the annular sleeve 25, and the structure is more stable.

[0065] The end of the tension bar 20 close to the rear fixing head 32 expands radially outward away from the main rod 19, and the end of the tension bar 20 close to the front fixing head 31 converges radially inward toward the main rod 19.

[0066] The tension-free yarn bundle is inserted into the outside of the tension bar 20 from the front fixed head 31 end, and the inwardly converging end plays a guiding role, making it easier for the tension-free yarn bundle to be inserted into the outside of the tension bar 20 with tension. By setting the positions of the spring 23, the annular sleeve 25 and the adjusting slider 26, a suitable position is selected according to different yarn bundle diameters. The spring 23 applies an outward tension so that the tension-free yarn bundle can always maintain a tight state on the tension bar 20, so that the active unwinding process can be completed smoothly. As the active unwinding process proceeds, the yarn on the tension bar 20 becomes less and less, and the inward pressure becomes smaller and smaller. The spring 23 can continue to apply pressure outward to keep the yarn bundle in a tight state at all times.

[0067] The hollow cavity 30 of the main rod 19 of the telescopic yarn support frame is inserted into the active unwinding bobbin shaft of the active unwinding automatic winder. Preferably, it is further fixed in the front with a fixed clamp to prevent it from falling off during the unwinding rotation process. During the unwinding process, the telescopic yarn support frame rotates with the active unwinding bobbin shaft, and the yarn is easily slipped outward due to the axial force of the rotation of the active unwinding bobbin shaft. The anti-slip protrusion and the outward expansion end of the tension bar 20 can work together to prevent the yarn from slipping and falling off.

[0076] The dyeing performance of the cheese yarns obtained in the above embodiments and comparative examples was tested, and the test results are shown in Table 1: 1. Knit socks on a knitting machine and measure the color difference between the inside and outside and between each piece.

[0077] Color difference between inside and outside: Take the inner, middle and outer parts of the loose cheese yarn and yarn bundle of the comparative example and the embodiment respectively to weave into inner-middle-outer-inner continuous knitted socks, and use gray card to judge the grade.

[0078] Color difference between pieces: (1) Randomly select 6 packages of yarn with different creel rods and different heights on the creel rods, weave them into continuous knitted socks, and use gray cards to determine the grade.

[0079] (2) Randomly select 6 yarn bundles of different heights and inner and outer layers of the embodiment, weave them into a continuous knitted sock tube, and use a gray card to determine the grade.

[0080] 2. Determine the color fastness of dyed yarn and evaluate it using a gray card.

[0081] 3. Strength reduction rate = (original yarn strength - colored yarn strength) / original yarn strength) × 100%.

[0082] Table 1 Test results

[0083] When using the dyeing machine before the improvement to dye cheese yarn, because the cheese yarn has tension and high density, in order to achieve a more uniform dyeing effect, it is necessary to increase the power of the circulation pump, which will cause a significant decrease in yarn strength. Even if loose winding is performed, the cheese yarn is not in a completely tension-free and relaxed state. It is impossible to achieve zero color difference in dyeing in this state. At the same time, the dye between the yarn rack rods of the device before the improvement is uneven, and different heights have a great impact on the dyeing color difference.
