Description

Technical Field

[0001] The invention relates to a flax processing technology, in particular to a flax softness processing technology. Background Art

[0002] Flax is a medicinal plant. Its seeds can be pressed to extract oil, and the bast fiber in the stems can be used to make various garments and decorations. Flax fibers are often rough and easy to knot, so they usually need to be treated before processing to make them more suitable for textile processing and other operations.

[0003] At present, the processing flow of flax fiber includes cleaning, primary processing, grading, fine processing and drying to form long fibers that are easy to process. Linen fabrics are also scoured by hot and cold water washing and soaking in enzyme solution. However, some residual impurities still exist in the dried flax fibers after simple washing, combing and soaking in enzyme solution. The structure of the fibers is easily damaged and the dried flax fibers become hard. The residual plant juice easily makes the fibers brittle, which is not conducive to fiber weaving and the preservation of related fabrics.

[0004] In view of the existing flax processing methods, technicians in this field have proposed a flax softness processing process to optimize the existing flax processing process, ensure the flexibility of the flax fibers after processing, and avoid the adverse effects of the processing process on the performance of the flax fabric. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a flax softness treatment process, in which the flax fibers that have been preliminarily treated are further treated for softness in a soaking tank, the residual plant tissues and pigments on the flax fibers are fully cleaned, the orderly arrangement of the flax fibers is destroyed, the macromolecular chains are changed into smaller molecular chains, the orientation degree and crystallinity of the fibers are reduced, the elongation at break and the flexibility of the fibers are increased, the feel of the flax fibers is improved, the fiber tissue is made more fluffy and fuller, the feel is softer by rubbing the rubber blanket, and the shrinkage rate of the fibers is controlled.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A flax softness treatment process comprises the following steps:

[0007] Rebleaching: After desizing, scouring and bleaching, some impurities may still remain on the flax fiber. In order to further improve the feel, the flax fiber is rebleached after mercerization, soaked in warm water, and repeatedly rolled and rubbed;

[0008] Bio-enzyme degradation: add cellulase to the soaking solution to treat the flax fibers, and pile them at 30°C for 3-4 hours;

[0009] Softening treatment, where linen is treated with a specific softener;

[0010] Pre-shrinking finishing, stretching and rubbing the linen fabric through a rubber blanket;

[0011] Washing and finishing: washing the treated flax fibers, draining the water and drying them;

[0012] The invention is characterized in that the processing equipment used in combination with the rebleaching and rolling and the rubber blanket rubbing steps specifically comprises:

[0013] A soaking tank, wherein the soaking tank is a container with an inner bottom surface having an inclined slope, in which the flax fibers are soaked and washed, and the inner bottom surface of the soaking tank having an inclined slope is more conducive to the flow of liquid when washing the flax fibers;

[0014] A roller, wherein the roller is arranged close to the inner bottom surface of the soaking tank which is arranged obliquely, and the flax fibers are rolled by rolling the roller close to the inner bottom surface of the soaking tank, and repeated rolling is conducive to removing impurities attached to the fibers;

[0015] The kneading rubber blanket is arranged between two rollers to stretch and rub the treated flax fibers. When the soaked flax fibers are pre-shrinked, the kneading rubber blanket is lowered, and the rollers are pressed against the kneading rubber blanket to stretch and rub the fibers.

[0016] Preferably, both ends of the soaking pool are respectively connected with a water inlet pipe and a water outlet pipe, and the water inlet pipe is arranged at the end with a higher bottom surface in the soaking pool to facilitate the filling and drainage of the soaking pool. The inner wall of the soaking pool is also fixedly provided with an electric heating row, and the soaking liquid in the soaking pool is heated or insulated by the electric heating row to ensure the ambient temperature of the treatment.

[0017] A partition is fixedly provided on the inner wall of the immersion tank, and a spoiler paddle is fixedly provided on the side of the partition. The partition forms a flow effect of the liquid in the immersion tank, which is beneficial to the temperature balance of the immersion liquid in the immersion tank and timely removes impurities discharged by the rolling roller through the water flow.

[0018] Preferably, the inner wall of the soaking tank is fixedly connected with a slide rail, and a pressure rod is slidably arranged on the inner side of the soaking tank through the slide rail. After the flax fibers are put into the soaking tank, the flax fibers are pressed down by the pressure rod to position them so that they are entangled with each other, which is beneficial to the distribution of the flax fibers in the soaking tank and the subsequent operation of the rollers.

[0019] A mounting rod is provided on the inner side of the soaking tank for vertical sliding with the water flow direction through a slide rail, and the roller is arranged to be pressed against the inner bottom surface of the soaking tank through the mounting rod. The driving control of the roller is achieved by driving the movement of the mounting rod.

[0020] The two mounting rods are arranged side by side up and down and front and back through two slide rails, so that the two rollers are arranged side by side in the soaking tank one after another, which facilitates the driving of the kneading rubber blanket in two opposite directions through the rollers.

[0021] Preferably, an extension sleeve is vertically fixed on the side of the mounting rod, a first spring is arranged inside the extension sleeve, an extension rod is slidably arranged on the extension sleeve through the first spring, and the roller bearing is arranged at the bottom end of the extension rod.

[0022] The roller is pressed against the inner bottom surface of the soaking tank by the extension rod installed tightly by the first spring, and the extension rod has a certain range of buffering. When the roller runs to the flax fiber to roll the fiber, not only the first spring is used to ensure the rolling effect on the fiber, but also when more fibers gather, the extension rod applies pressure to the first spring to deform it, and the extension rod moves into the extension sleeve to prevent the accuracy of the equipment from changing during use.

[0023] Preferably, a slider is slidably disposed inside the extension sleeve, and the first spring is fixedly connected to the side of the slider. The rolling pressure of the roller on the flax fiber can be adjusted by adjusting the installation position of the slider.

[0024] The side of the extension sleeve is slidably sleeved with an outer cylinder, the slider penetrates the side wall of the extension sleeve and is slidably engaged with the outer cylinder, the sides of the extension sleeve and the outer cylinder are vertically provided with sliding grooves adapted to the slider, the slider can slide and adjust relative to the extension sleeve and the outer cylinder respectively through the sliding grooves, the sliding grooves on the side of the outer cylinder have a positioning effect on the slider, and the positioning of the slider and the outer cylinder can be achieved by rotating the outer cylinder after the slider slides to a suitable position.

[0025] The top end of the outer cylinder is rotatably connected to a threaded cylinder, which is threadedly connected to the side wall of the extension sleeve. The threaded cylinder adjusts the installation position on the side of the extension sleeve through the threaded connection relationship, and at the same time has a positioning effect on the slider fixed to the outer cylinder through the connection relationship between the threaded cylinder and the outer cylinder.

[0026] When the fiber is re-bleached and rolled by the roller, the slider is positioned with the outer cylinder, and the outer cylinder carries the slider to slide along the slide groove on the side of the extension sleeve. The pressing force of the first spring on the roller is adjusted by the threaded cylinder. When the fiber is pre-shrinked, the outer cylinder is rotated to cancel the positioning of the slider by the outer cylinder, so that the advancing rod can smoothly advance when the rubbing rubber blanket moves with the roller. The rubbing rubber blanket extends to the bottom of the roller to directly contact the fiber. The slider and the outer cylinder are then positioned, and the threaded cylinder is rotated to adjust the pressing force of the roller on the rubbing rubber blanket, so as to facilitate the expansion and contraction of the fiber.

[0027] Preferably, a driving belt is provided between the two parallel slide rails, and the driving belt is transmission-connected to a power mechanism, and the driving belt is driven to circulate by the power mechanism. A protrusion is fixedly provided on the side of the driving belt, and the driving belt contacts the driving mounting rod through the protrusion on the side.

[0028] A shifting block corresponding to the protrusion is hingedly provided on the side of the mounting rod, a fixing block is fixedly connected to the side of the mounting rod parallel to the shifting block, and a second spring is provided between the shifting block and the fixing block.

[0029] After the shift block set tightly by the second spring contacts the side protrusion of the driving belt, the mounting rod moves along the slide rail together with the driving belt under the action of the driving belt. When the mounting rod encounters a large obstacle, the shift block applies the thrust applied by the driving block through the protrusion to the second spring. The second spring is compressed and deformed, causing the shift block to rotate out of the range of the protrusion. After the driving belt rotates, it contacts the shift block on the side of the other mounting rod, applying thrust in the opposite direction to the mounting rod, thereby realizing drive control of the roller in two opposite directions.

[0030] Preferably, the fixing block is fixedly connected to a mounting sleeve on one side close to the shifting block, the second spring extends into the inner side of the mounting sleeve at one end away from the shifting block, and a tightening bolt is inserted through the mounting sleeve on the side of the fixing block.

[0031] The second spring applies a thrust to the fixed block via the mounting sleeve, thereby preventing the angle at which the rotationally adjusted shift block applies a thrust to the fixed block from changing when rotating, thereby causing the second spring to slip sideways when contacting the inclined side wall of the fixed block, affecting the driving effect; the contact position of the second spring and the fixed block is controlled by inserting a tightening bolt that extends into the mounting sleeve and is arranged on the side of the fixed block, thereby controlling the pushing force of the shift block on the fixed block.

[0032] Preferably, a winding drum is fixedly connected to the side of the extension rod used for installing the roller, a winding roller is arranged through the central axis of the winding drum, and the kneading rubber blanket is wound by the winding roller and arranged between the two rollers.

[0033] The retraction and extension of the kneading rubber blanket is adjusted by the winding roller. In the re-bleaching and soaking process, only the rolling effect of the roller on the fiber is needed, while in the pre-shrinking finishing process, the kneading rubber blanket is put down, and the kneading rubber blanket is pressed against the inner bottom surface of the soaking tank by the rolling roller to slide, and the kneading rubber blanket is used to expand and contract and knead the fiber.

[0034] Preferably, the winding roller is connected to the drum bearing, and a limit strip is hingedly provided on one end of the drum, a positioning seat corresponding to the limit strip is fixedly provided on the side of the drum end, and a limit wedge block is inserted into the inner side of the positioning seat through a spring to tighten it.

[0035] The retraction and extension control of the side-wound rubbing rubber blanket is achieved by passing the winding roller through the end of the reel. After the rubbing rubber blanket is released to a sufficient length, the limit strip hinged at the end is rotated to enable the limit strip to realize the rotation positioning of the winding roller through the positioning seat. The rubbing rubber blanket will not be continuously stretched due to the friction between it and the bottom surface of the immersion tank, thereby ensuring the rubbing effect on the fiber. The limit wedge block set by the spring automatically presses tightly to realize the positioning of the limit strip.

[0037] S1. The flax fibers that have been pre-treated are placed in the soaking tank, a sufficient amount of warm water is added to the soaking tank, the flax fibers are stirred to make them evenly distributed, the warm water is heated by the electric heating row and the temperature is controlled at 70° C., and the flax fibers are soaked for two hours;

[0038] The pressing rod is slid to press and position the flax fibers, and the driving belt is started. The driving belt drives the roller to repeatedly roll the flax fibers along the pressing rod, and the spoiler paddle is started to keep the flow of the soaking liquid, so as to fully discharge the impurities such as plant pigments and pulp attached to the fibers, and the soaking liquid is discharged after the rolling is completed;

[0039] S2, passing warm water into the soaking tank, adding cellulase to the warm water, maintaining the soaking liquid temperature at 55°C, destroying the orderly arrangement of the flax fibers, converting the macromolecular chains into smaller molecular chains, reducing the orientation and crystallinity of the fibers, thereby increasing the breaking elongation and flexibility of the fibers, and stacking them at 30°C for 3-4 hours to fully degrade the impurities remaining in the fibers;

[0040] S3, passing warm water into the soaking pool, adding a specific softener into the warm water and soaking for 2 hours to improve the hand feel, and draining the soaking liquid after the soaking is completed;

[0041] S4, lowering the kneading blanket, and using the roller to press against the kneading blanket to stretch and knead the flax fibers, so that the fabric is more fluffy, fuller, and softer, and it helps to control the shrinkage rate;

[0042] S5. Hot water and cold water are introduced into the soaking pool successively to clean the flax fibers, and the moisture is drained and the flax fibers are dried. High-temperature hot air enters the fibers to make the fabric fluffy and thick, and the surface becomes soft and plump.

[0043] The present invention discloses a flax softness treatment process, which has the following beneficial effects:

[0044] 1. The flax softness treatment process is designed for the process of flax fiber softness treatment and the supporting treatment equipment, and further softness treatment is carried out on the preliminarily treated flax fiber. The flax fiber is soaked in warm water in a soaking tank, rolled by rollers and treated with biological enzymes in turn to further remove residual impurities in the fiber, increase the glossiness of the fiber, reduce the orientation and crystallinity of the fiber, increase the breaking elongation and flexibility of the fiber, and then soak it in a softener to increase the softness of the fiber. The flax fiber is rubbed with a rubber blanket to make the fiber tissue more fluffy and fuller, and the hand feel is softer, which helps to control the shrinkage rate of the fiber.

[0045] 2. In the flax softness treatment process, the driving belt drives the mounting rod to move back and forth in the soaking tank to realize the reciprocating rolling drive of the roller, which is beneficial to the multiple rolling operation of the flax fiber. The kneading rubber blanket is arranged between the two rollers, which is convenient for the rollers to apply driving and pressing effects to the kneading rubber blanket, so as to realize the rolling and tanning of the flax fiber with a certain pressure, thereby ensuring the effect of the rolling and tanning.

[0046] 3. In the flax softness treatment process, the inner bottom surface of the soaking tank is set as an inclined structure to facilitate the water supply and drainage of the soaking tank. In addition, the pressure rod set by the sliding rail is used to position the evenly distributed flax fibers, which is convenient for the subsequent processing of the flax fibers by the roller and the rubbing rubber blanket.

DETAILED DESCRIPTION

[0058] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] The embodiment of the present invention discloses a flax softness treatment process;

[0060] S1. The flax fibers that have been pre-treated are placed in the soaking tank, a sufficient amount of warm water is added to the soaking tank, the flax fibers are stirred to make them evenly distributed, the warm water is heated by the electric heating row and the temperature is controlled at 70° C., and the flax fibers are soaked for two hours;

[0061] The pressing rod is slid to press and position the flax fibers, and the driving belt is started. The driving belt drives the roller to repeatedly roll the flax fibers along the pressing rod, and the spoiler paddle is started to keep the flow of the soaking liquid, so as to fully discharge the impurities such as plant pigments and pulp attached to the fibers, and the soaking liquid is discharged after the rolling is completed;

[0062] S2, passing warm water into the soaking tank, adding cellulase to the warm water, maintaining the soaking liquid temperature at 55°C, destroying the orderly arrangement of the flax fibers, converting the macromolecular chains into smaller molecular chains, reducing the orientation and crystallinity of the fibers, thereby increasing the breaking elongation and flexibility of the fibers, and stacking them at 30°C for 3-4 hours to fully degrade the impurities remaining in the fibers;

[0063] S3, passing warm water into the soaking pool, adding a specific softener into the warm water and soaking for 2 hours to improve the hand feel, and draining the soaking liquid after the soaking is completed;

[0064] S4, lowering the kneading blanket, and using the roller to press against the kneading blanket to stretch and knead the flax fibers, so that the fabric is more fluffy, fuller, and softer, and it helps to control the shrinkage rate;

[0065] S5. Hot water and cold water are introduced into the soaking pool to clean the flax fibers, and the water is drained and dried. High-temperature hot air enters the fibers to make the fabric fluffy and thick, and the surface becomes soft and plump.

[0066] According to the attached Figure 1 As shown, it includes a soaking tank 1, in which a roller 2 is slidably arranged, and a rubbing rubber blanket 3 is arranged between the two rollers 2. The soaking tank 1 is a container with an inclined inner bottom surface, which is used to clean and soak flax fibers. The flax fibers are placed in the soaking tank 1, filled with soaking liquid for soaking and cleaning, and rolled by the roller 2 to help remove residual impurities. The rubbing rubber blanket 3 arranged between the two rollers 2 is used to stretch and rub the flax fibers, so that the fabric structure is more fluffy, fuller, and softer, and it helps to control the shrinkage rate.

[0067] The upper and lower ends of the inner bottom of the soaking tank 1 are respectively penetrated by a water inlet pipe 4 and a water outlet pipe 5, which is convenient for storing water in the soaking tank 1 for soaking the flax fibers and for discharging the soaking liquid. At the same time, the soaking tank 1 with an inclined inner bottom is beneficial to the cleaning of the flax fibers.

[0068] According to the attached Figure 2 As shown, an electric heating row 6 is fixedly provided on the inner wall of the soaking pool 1, and the soaking liquid in the soaking pool 1 is heated by an external power supply to meet the control of the temperature of the soaking liquid in the soaking pool 1.

[0069] A partition 7 is fixedly arranged on the inner side of the soaking tank 1, through which a flow boundary of the liquid is formed in the soaking tank 1, and a spoiler paddle 8 is arranged on the side of the partition 7, through which the soaking liquid is driven to flow along the partition 7, so as to help the electric heating row 6 to maintain the circulating heating of the soaking liquid in the soaking tank 1, and at the same time, it is beneficial for the roller 2 to promptly take away the impurities separated from the flax fiber when rolling the flax fiber.

[0070] According to the attached Figure 2-3As shown, a slide rail 9 is fixedly provided on the inner wall of the soaking tank 1, and a pressure rod 10 is slidably provided vertically on the inner bottom surface of the soaking tank 1 through the slide rail 9. After the flax fibers soaked in the soaking tank 1 are orderly dispersed, the flax fibers are compacted by pressing the pressure rod 10 downward, so as to facilitate the subsequent rolling of the flax fibers by the roller 2.

[0071] In addition, a mounting rod 11 is slidably arranged in parallel to the ground in the soaking tank 1 through the slide rail 9, and the roller 2 is slidably arranged against the inner bottom surface of the soaking tank 1 through the mounting rod 11. The mounting rod 11 is driven to move laterally along the slide rail 9, thereby realizing the rolling of the flax fiber by the roller 2 along the pressure rod 10.

[0072] According to the attached Figure 4-5 As shown, an extension sleeve 12 is fixedly arranged on the side of the mounting rod 11 vertically on the ground, a first spring 13 is arranged on the inner side of the extension sleeve 12, and an extension rod 14 is pressed against by the first spring 13, and a roller 2 is rotatably arranged at the bottom of the extension rod 14, and the first spring 13 applies a pressing force to the extension rod 14, so that the roller 2 presses the flax fiber with a certain pressing force and rolls it, which is beneficial to rolling the soaked flax fiber and removing residual impurities.

[0073] A slider 15 is slidably provided on the inner side of the extension sleeve 12, and the first spring 13 is fixedly provided between the slider 15 and the extension rod 14. The side of the extension sleeve 12 is also slidably sleeved with an outer cylinder 16, and the side walls of the extension sleeve 12 and the outer cylinder 16 are penetrated with a slide groove 17. The side of the slider 15 is symmetrically fixed with a mounting block that adapts to the slide groove 17. The slider 15 slides along the slide groove 17 on the side of the extension sleeve 12 through the mounting block. The mounting block on the side of the slider 15 penetrates the extension sleeve 12 and is positioned and clamped with the side slide groove 17 of the outer cylinder 16, so as to realize the positioning of the installation position of the slider 15 through the outer cylinder 16.

[0074] The end of the outer cylinder 16 is rotatably connected with a threaded cylinder 18 , which is threadedly connected to the side wall of the extension sleeve 12 . The threaded cylinder 18 can position and adjust the outer cylinder 16 through the threaded connection relationship with the extension sleeve 12 .

[0075] The slide groove 17 opened on the side of the outer cylinder 16 is slightly different from the slide groove 17 on the side of the extension sleeve 12. The slide groove 17 opened and closed on the side of the extension sleeve 12 only needs to realize the sliding adjustment of the slider 15 in the extension sleeve 12, while the slide groove 17 on the side of the outer cylinder 16 not only needs the sliding adjustment function, but also needs to have a positioning function for the slider 15. Generally, when the flax fiber is rolled by the roller 2, the outer cylinder 16 positions the slider 15, and then the threaded cylinder 18 adjusts the pressing force of the first spring 13 on the roller 2 to ensure the rolling effect of the roller 2.

[0076] When the rubbing rubber blanket 3 is driven by the roller 2, the outer cylinder 16 is first rotated to cancel the positioning of the slider 15, so that the rubbing rubber blanket 3 enters under the roller 2 and then the outer cylinder 16 is rotated to position it, thereby avoiding the problem of complicated adjustment of the threaded cylinder 18 during the switching process between the roller 2 and the rubbing rubber blanket 3 for different usage requirements.

[0077] According to the attached Figure 6-7 As shown, a rotating shaft is provided through the inner wall of the soaking tank 1 , a driving belt 19 is provided in the soaking tank 1 via the rotating shaft, a protrusion 20 is fixedly provided on the side of the driving belt 19 , and the driving belt 19 drives the mounting rod 11 via the protrusion 20 .

[0078] A shift block 21 is rotatably sleeved on the side of the mounting rod 11. The shift block 21 can rotate relative to the mounting rod 11 in the absence of other external forces and structural restrictions. A fixed block 22 corresponding to the shift block 21 is fixedly arranged on the side of the mounting rod 11, and a second spring 23 is arranged on the side of the fixed block 22 to press against the shift block 21.

[0079] The shift block 21 is restricted from rotating under the pressing action of the second spring 23. When the driving belt 19 is running, the side projection 20 contacts the shift block 21 and applies a thrust to the shift block 21. Under the thrust, the shift block 21 compresses the side second spring 23. After the mounting rod 11 moves to the limit position, the pressure is fully applied to the second spring 23. The shift block 21 is deflected to break away from the contact with the projection 20 through the buffering of the second spring 23 until the driving belt 19 returns through the rotating shaft. The side projection 20 again acts on the shift block 21 on the side of the other mounting rod 11 to drive it to move in the opposite direction, thereby realizing the reciprocating drive of the roller 2 and the rubbing rubber blanket 3 in opposite directions.

[0080] A mounting sleeve 24 is fixedly provided on the side of the fixed block 22 close to the shift block 21, and the second spring 23 extends into the inner side of the mounting sleeve 24 at one end away from the shift block 21, so as to prevent the fixed block 22 of the second spring 23 from slipping between the side wall of the fixed block 22 due to the change of force direction caused by the rotation of the shift block 21.

[0081] A tightening bolt 25 is also provided on the side of the fixed block 22. The tightening bolt 25 is threadedly connected to the fixed block 22, and the tightening bolt 25 extends into the inner side of the mounting sleeve 24. By adjusting the position of the tightening bolt 25, the distance of the second spring 23 extending into the mounting sleeve 24 can be adjusted, thereby adjusting the tightening force of the shift block 21.

[0082] According to the attached Figure 8-9As shown, a reel 26 is fixedly arranged on the side of a group of extension rods 14, and a winding roller 27 is arranged on the bearing at the central axis position of the reel 26. The kneading rubber blanket 3 is wound by the winding roller 27 and arranged in the reel 26. When the roller 2 is rolling the flax fiber, the kneading rubber blanket 3 is wound in the reel 26 to avoid affecting the operation of the roller 2. When the kneading rubber blanket 3 is in the telescopic kneading process, a sufficient length of the kneading rubber blanket 3 is released for use with the roller 2.

[0083] The winding roller 27 passes through one end of the winding drum 26 and is hingedly provided with a limit strip 28 for controlling the rotation of the winding roller 27. A positioning seat 29 corresponding to the limit strip 28 is fixedly provided at the end of the winding drum 26. The limit strip 28 is bent and enters the range of the positioning seat 29 to perform rotation positioning of the winding roller 27. A limit wedge block 30 is also provided on the inner side of the positioning seat 29 through spring insertion, which applies a force to the limit strip 28 to achieve rapid positioning of the limit wedge block 30.

[0084] The flax softness treatment process and device are designed for the process of flax fiber softness treatment and the supporting treatment equipment, and further softness treatment is performed on the preliminarily treated flax fiber. The flax fiber is sequentially soaked in warm water in a soaking tank 1, rolled by a roller 2 and treated with a biological enzyme, so as to further remove residual impurities in the fiber, increase the glossiness of the fiber, reduce the orientation degree and crystallinity of the fiber, increase the breaking elongation and flexibility of the fiber, and then soak it in a softener to increase the softness of the fiber. Then, the flax fiber is rubbed with a rubber blanket to make the fiber tissue more fluffy and fuller, and the hand feel is softer, which is helpful to control the shrinkage rate of the fiber. Finally, the fiber is washed with hot water and cold water, and dried at high temperature to make the fiber fluffy and thick, and the surface becomes soft and full.

[0085] Furthermore, the inner bottom surface of the soaking tank 1 is arranged as an inclined structure, which is convenient for water supply and drainage of the soaking tank 1 and cleaning of the flax fibers. In addition, the pressure rod 10 slidingly arranged on the slide rail 9 is used to position the evenly distributed flax fibers, which is convenient for subsequent processing of the flax fibers by the roller 2 and the rubbing rubber blanket 3.

[0086] Furthermore, the driving belt 19 in the soaking tank 1 drives the mounting rod 11 to reciprocate to realize the reciprocating rolling drive of the roller 2, which is beneficial to the multiple rolling operation of the flax fiber. The kneading rubber blanket 3 is arranged between the two rollers 2, which is convenient for the roller 2 to apply driving and pressing action to the kneading rubber blanket 3, so as to realize the rolling and tanning of the flax fiber with a certain pressure, thereby ensuring the effect of rolling and tanning.
