Description

Technical Field

[0001] The present invention relates to the technical field of cashmere knitted sweater production, and specifically to a production process of high-performance anti-mite cashmere knitting yarn. Background Art

[0002] High-performance anti-mite cashmere knitting yarn is a textile material with special functions. It combines the high-quality characteristics of cashmere and the anti-mite function, meeting the multiple needs of modern consumers for health, comfort and fashion. The production process of high-performance anti-mite cashmere knitting yarn involves multiple key steps to ensure that the yarn has anti-mite function and high performance. First, high-quality cashmere needs to be selected to ensure the fiber fineness, length and strength. Subsequently, the cashmere needs to be cleaned to remove the oil and impurities in the cashmere. After cleaning, the cashmere needs to be treated with anti-mite agents. The anti-mite agents are mainly applied evenly to the cashmere fibers by impregnation. After the anti-mite treatment, the cashmere is subjected to corresponding spinning processes (i.e., opening and mixing, carding, drawing, roving, spinning, etc.). Subsequently, heat setting and cleaning and drying operations are carried out on the cashmere. When using the impregnation process to treat cashmere, first, the cashmere fibers need to be soaked in the anti-mite agent solution. During the soaking process, the soaking time, temperature and agent concentration need to be controlled to ensure that the agent penetrates sufficiently. After soaking, the fibers are taken out and dried to fix the agent on the fiber surface. However, in the actual working process, during the soaking process of cashmere fibers, due to the dense scales on the surface of cashmere, a physical barrier will be formed, which will hinder the penetration of the agent into the cortical layer. In some processes, mechanical stirring is used for treatment. Although it can effectively improve the agent penetration rate, the mechanical stirring treatment only forms local turbulence, and the inside of the fiber bundle is still in a laminar flow state. The agent may not be able to penetrate the fiber gaps, which is likely to cause insufficient and uneven combination between the cashmere fibers and the agent, resulting in a relatively rough and hard hand feeling of the yarn. Therefore, we propose a production process of high-performance anti-mite cashmere knitting yarn. Summary of the Invention

Specific embodiments

[0016] 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 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.

[0017] Please refer to Figure 1-16 , the present invention provides a technical solution: a production process of a high-performance anti-mite cashmere knitted yarn, and the method includes the following steps: a. Raw material inspection: Select high-quality cashmere fibers with a fineness ≤ 16.5 μm and a length ≥ 35 mm, and conduct microbial detection on the raw materials; b. Anti-mite treatment of raw materials: Select anti-mite additives according to the performance of cashmere knitted sweaters, and use the impregnation process to treat the raw cashmere. After treatment, rinse with soft water at 35 °C until the pH is 6.5 - 7.0. The treated fibers need to be balanced for 24 hours in an environment with a constant temperature of 22 °C ± 2 and a relative humidity of 60% to restore the moisture regain rate; during this process, it is necessary to ensure that the additive and cashmere are evenly mixed, including a frame 1, a metal barrel body 2 fixedly installed on the frame 1 and used for containing the soaking additive, an impregnation barrel 3 installed inside the metal barrel body 2 and rotatably connected to the metal barrel body 2. Two metal partitions 31 are fixedly installed inside the impregnation barrel 3, and a plurality of filter holes 32 are opened on the impregnation barrel 3 and the two metal partitions 31.

Metal sleeves 4 are symmetrically installed at both ends of the metal barrel body 2, the metal sleeves 4 are located in the arc-shaped grooves 33, and a connecting portion 50 is arranged inside the metal sleeve 4. A fixed plate frame 53 is also arranged on the connecting portion 50. A pressing portion 54 for pressing the cashmere is arranged on the fixed plate frame 53. A plurality of guiding shafts 55 are arranged between the pressing portion 54 and the fixed plate frame 53, and a buffer spring 56 is sleeved on each guiding shaft 55. A power unit 11 for driving the impregnation barrel 3 to rotate is also arranged on the metal barrel body 2; c. Mixing ratio: Premix cashmere and functional fibers, and add antistatic agents during the premixing process to reduce carding entanglement; d. Carding and roving formation: Adopt the process of "light weight per unit length and low speed", enlarge the cylinder-apron gauge to 0.25 mm, and the licker-in speed ≤ 650 rpm to reduce fiber damage; control the roving weight per unit length at 18 - 20 g / 5 m to ensure uniform mixing; e. High count spinning of fine yarn: Compact spinning process: The negative pressure in the gathering area is 3500 Pa, the yarn hairiness is reduced by 60%, and the attachment efficiency of the anti-mite agent is improved; select the twist factor of 380 - 400 to balance strength and softness; f. Winding and packaging: Electronic yarn clearer setting: Cut off short thick knots +150% × 2 cm and long thin knots -40% × 30 cm, and use anti-mildew and antibacterial packaging materials for vacuum-sealed storage; g. Anti-mite re-finishing: Treat the product by padding, then carry out water washing and shaping processes, and conduct durability tests on the product after completion; h. Bag and box the finished cashmere knitted yarn as needed.

[0018] An inclined baffle 21 is also fixedly installed at the feeding part of the metal barrel body 2 in step b. As a further limitation in the present invention, the connecting part 50 includes a connecting rod frame 5 installed inside the metal sleeve 4 and rotatably connected to its inner wall. A plurality of square frames 51 are fixedly installed on the connecting rod frame 5, and a connecting shaft body 52 slidably connected to the inner wall is installed in each square frame 51. The fixing plate frame 53 is fixedly connected to the plurality of connecting shaft bodies 52. The power unit 11 in the present invention includes a mounting frame 8 fixedly installed at one end of the metal barrel body 2. One end of the impregnation barrel 3 is provided with a sliding shaft body 6 slidably connected to its inner wall, and one end of the metal barrel body 2 is provided with a meshing gear 7 rotatably connected to its end. A plurality of sliding blocks 71 are fixedly installed on the inner wall of the meshing gear 7. A plurality of sliding grooves 61 and an annular groove 62 are formed on the outer wall of the sliding shaft body 6. The sliding blocks 71 correspond to the sliding grooves 61 one by one and are limited to slide in the sliding grooves 61 and the annular groove 62. Two transmission gears 9 both in meshing engagement with the meshing gear 7 are arranged inside the mounting frame 8. The transmission gears 9 correspond to the metal sleeves 4 one by one. A transmission unit 10 is arranged between the transmission gears 9 and the connecting rod frame 5. A servo motor 81 is fixedly installed on the outer wall of the mounting frame 8. One of the transmission gears 9 is fixedly connected to the output end of the servo motor 81, and the other transmission gear 9 is rotatably connected to the inner wall of the mounting frame 8; Combined with the attached Figure 1 and the attached Figure 2 As shown, a collection bin is also fixedly installed on the frame 1. A valve is also installed on the metal barrel body 2. The auxiliary agent in the metal barrel body 2 can be discharged into the collection bin through the valve. The cashmere is placed in the impregnation barrel 3. The auxiliary agent in the metal barrel body 2 enters the impregnation barrel 3 through the filter holes 32 on the impregnation barrel 3, and the cashmere is soaked in the auxiliary agent. Combined with the attached Figure 3 and the attached Figure 4 As shown, no filter holes 32 are provided in the area of the impregnation barrel 3 between the two metal partitions 31.

[0019] Furthermore, the present invention adopts the method of "taking out the cashmere from the auxiliary agent, pressing it, and then soaking it again" to process the cashmere. Compared with the stirring treatment in the prior art, the pressing operation can make the cashmere fiber bundles be directionally extruded in the liquid auxiliary agent, physically destroying the closed state of the scale layer, and the penetration depth of the auxiliary agent is relatively high. When mechanically stirring in the prior art, a concentration gradient of the auxiliary agent (the concentration of the outer layer is higher than that of the core) is formed inside the fiber bundle due to capillary action, while pressing can force the renewal of the auxiliary agent contact liquid in the core.

[0020] A constant force spring 63 is connected between the sliding shaft body 6 and the inner wall of the impregnation barrel 3. One end of the sliding shaft body 6 is fixedly installed with a magnetic plate frame 64. The magnetic plate frame 64 is located on one side of the meshing gear 7, and a plurality of clamping shaft bodies 65 are fixedly installed on the magnetic plate frame 64. A limiting sleeve 82 is fixedly installed on the inner wall of the mounting frame 8. A plurality of clamping holes 83 corresponding to the clamping shaft bodies 65 one by one are opened on the limiting sleeve 82. An electromagnetic component 84 is fixedly installed inside the limiting sleeve 82. When the electromagnetic component 84 is energized, an attractive force is generated on the magnetic plate frame 64. Thus, when the electromagnetic component 84 is energized, an attractive force is generated on the magnetic plate frame 64, so that the clamping shaft body 65 enters the clamping hole 83 under the action of the magnetic plate frame 64. When the clamping shaft body 65 enters the clamping hole 83, the sliding block 71 on the meshing gear 7 enters the annular groove 62 from the sliding groove 61. Then, when the meshing gear 7 rotates, the sliding shaft body 6 does not rotate with the meshing gear 7, and the impregnation barrel 3 remains stationary.

[0021] Furthermore, through the magnetic relationship between the electromagnetic component 84 and the magnetic plate frame 64, the impregnation barrel 3 can be fixed after adjusting a certain angle in the metal barrel body 2, so that the transmission gear 9 controls the connecting rod frame 5 to rotate through the transmission unit 10. Thus, the square frame 51 on the connecting rod frame 5 drives the pressing part 54 to press the cashmere from which the auxiliary agent has been separated through the connecting shaft body 52 and the fixed plate frame 53. Through pressing, the auxiliary agent can be more evenly distributed, effectively improving the utilization rate of the auxiliary agent. At the same time, pressing can prevent fiber caking and ensure the processability of the fiber in the subsequent process.

[0022] During the pressing process of the cashmere, the pressing part 54 in the present invention can be designed as follows according to the situation of the cashmere: Combined with the attached Figure 13 As shown in the figure, when there is no caking condition in the cashmere placed in the impregnation barrel 3, the pressing part 54 includes a connecting seat body 541 arranged on one side of the fixed plate frame 53. The connecting seat body 541 is slidably connected to the fixed plate frame 53 through a guiding shaft body 55. A flexible roller 542 rotatably connected thereto is also installed on the connecting seat body 541. Then, the flexible roller 542 can effectively press the cashmere, making the auxiliary agent more evenly distributed and avoiding too high or too low local concentration; Combined with the attached Figure 16As shown, when there is partial caking of the cashmere placed in the impregnation bucket 3, the pressing part 54 includes a needle group 543 fixedly installed on the fixing plate frame 53. On one side of the fixing plate frame 53, there is also an arc plate frame 544. The arc plate frame 544 is slidably connected to the fixing plate frame 53 through a guiding shaft body 55. The arc plate frame 544 is provided with holes corresponding to the needle group 543 one by one. Since the arc plate frame 544 is slidably connected to the fixing plate frame 53 through the guiding shaft body 55, and a buffer spring 56 (the buffer spring 56 is sleeved on the guiding shaft body 55) is connected between the arc plate frame 544 and the fixing plate frame 53. Therefore, during the pressing process, the cashmere fibers apply a force to the arc plate frame 544, causing the needle group 543 to be exposed from the arc plate frame 544, so as to effectively comb the cashmere through the needle group 543 and improve the caking condition of the cashmere. In order to avoid damaging the cashmere during the combing process, the needle group 543 in the present invention is preferably made of a material with high flexibility, such as silica gel, rubber and other materials.

[0023] As a further limitation in the present invention, the transmission unit 10 includes an annular disc frame 101 fixedly installed on the transmission gear 9. The annular disc frame 101 is located on one side of the transmission gear 9, and a fixed seat body 102 is fixedly installed on the annular disc frame 101. A plurality of fixed seat bodies 102 are fixedly installed on the annular disc frame 101, and a plurality of acting rod frames 103 are installed in the fixed seat body 102. One end of the acting rod frame 103 is rotatably connected to the fixed seat body 102, and a constant torque spring 104 is connected between the end of the acting rod frame 103 and the fixed seat body 102. It should be noted that, in combination with the attached Figure 9 and the attached Figure 10 , one side of each fixed seat body 102 is open, and the other side of the fixed seat body 102 is closed; on one side of the annular disc frame 101, there is also a force receiving disc frame 105. The center lines of the force receiving disc frame 105 and the annular disc frame 101 do not coincide, and the force receiving disc frame 105 is fixedly connected to the connecting rod frame 5. A variable torque spring 106 is connected between the force receiving disc frame 105 and the metal sleeve 4. A force receiving shaft body 107 is also fixedly installed on the force receiving disc frame 105, and the force receiving shaft body 107 is located on the movement track of the acting rod frame 103; Furthermore, for the convenience of description, the present invention is illustrated by examples: in combination with the attached Figure 9 、the attached Figure 10 and the attached Figure 11 as shown, according to the b diagram in the attached Figure 11 , the transmission gear 9 connected to the output end of the servo motor 81 rotates clockwise, the meshing gear 7 rotates counterclockwise, and another transmission gear 9 rotatably connected to the inner wall of the additional frame 8 rotates clockwise synchronously. Then, in combination with the attached Figure 9 and the attached Figure 10, when the transmission gear 9 connected to the output end of the servo motor 81 rotates clockwise, the annular disc frames 101 on the two transmission gears 9 rotate synchronously with it. When both annular disc frames 101 rotate clockwise, the fixed seat body 102 on the annular disc frame 101 will drive the action rod frame 103 to move synchronously; Continuing from the above, in combination with the attached Figure 9 As shown, since one side of the fixed seat body 102 is open and the other side is closed, when the action rod frames 103 corresponding to the two transmission gears 9 contact the force-bearing shaft body 107, when the action rod frame 103 corresponding to the transmission gear 9 connected to the output end of the servo motor 81 receives the reaction force from the force-bearing shaft body 107, the closed-side of the fixed seat body 102 will prevent the reverse movement of the action rod frame 103. Thus, under the action of the closed-side of the fixed seat body 102, the action rod frame 103 applies a force to the force-bearing shaft body 107, causing the force-bearing shaft body 107 to drive the force-bearing disc frame 105 to rotate. When the action rod frame 103 corresponding to the transmission gear 9 rotatably connected to the inner wall of the mounting frame 8 receives the reaction force from the force-bearing shaft body 107, at this time, the open side of the fixed seat body 102 is located on the movement trajectory of the action rod frame 103 when it receives the force. Therefore, the fixed seat body 102 will not hinder the rotation of the action rod frame 103. Under the action of the constant-torque spring 104, the action rod frame 103 rotates and moves away from the force-bearing position of the force-bearing shaft body 107. Thus, when the transmission gear 9 connected to the output end of the servo motor 81 rotates clockwise, the transmission gear 9 connected to the output end of the servo motor 81 will apply a force to the force-bearing shaft body 107 under the action of the action rod frame 103, and the action rod frame 103 corresponding to the transmission gear 9 rotatably connected to the inner wall of the mounting frame 8 will not apply a force to the force-bearing shaft body 107. When the transmission gear 9 rotates counterclockwise, the transmission gear 9 rotatably connected to the inner wall of the mounting frame 8 will apply a force to the force-bearing shaft body 107 under the action of the action rod frame 103, while the action rod frame 103 corresponding to the transmission gear 9 connected to the output end of the servo motor 81 will not apply a force to the force-bearing shaft body 107; It should be noted that since the rotation directions of the meshing gear 7 and the transmission gear 9 are opposite, when the meshing gear 7 rotates, the meshing gear 7 causes the impregnation barrel 3 to rotate under the action of the sliding shaft body 6, and the cashmere in the impregnation barrel 3 will cause some cashmere to leave the auxiliaries under the action of the metal partition 31; in combination with Figure 11 As shown in Figure a of the attachment, since the center lines of the force-bearing disc frame 105 and the annular disc frame 101 do not coincide, after the action rod frame 103 drives the force-bearing shaft body 107 to rotate a certain angle, the action rod frame 103 will not contact the force-bearing shaft body 107. Therefore, the force-bearing disc frame 105 will move in the reverse direction under the action of the variable-torque spring 106.

[0024] Further, an arc-shaped outer frame 41 is fixedly installed between the metal sleeves 4, and a magnetic part 42 is fixedly installed on the inner wall of the arc-shaped outer frame 41. The end of the connecting shaft body 52 is a magnetic end, and the magnetic part 42 is located on the movement track of the end of the connecting shaft body 52. The magnetic poles of the magnetic end of the connecting shaft body 52 and the magnetic part 42 are the same. A return spring 43 is connected between the end of the connecting shaft body 52 and the inner wall of the square frame 51. An annular baffle 57 is arranged inside the square frame 51, and a rotating shaft body 58 rotatably connected to the inner wall of the square frame 51 is fixedly installed on the annular baffle 57. One end of the rotating shaft body 58 is located outside the square frame 51, and a driving rod frame 59 is fixedly installed at one end of the rotating shaft body 58. Two force application rod frames 44 are fixedly installed near both ends of the arc-shaped outer frame 41, and the force application rod frames 44 are located on the movement track of the driving rod frame 59.

[0025] Specifically, in the actual use process, the staff puts the cashmere into the impregnation barrel 3 through the feeding part of the metal barrel body 2. During the putting process, under the action of the inclined baffle 21, the cashmere falls between the two metal partitions 31. Subsequently, an auxiliary agent is introduced into the metal barrel body 2, and the auxiliary agent contacts the cashmere under the action of the filter holes 32. During the soaking process of the cashmere, the cashmere is pressed regularly. In order to make the auxiliary agent evenly distributed in the cashmere, the present invention adopts the method of "taking out the cashmere from the auxiliary agent, pressing it, and then re-soaking it" for treatment. The specific operation is as follows: The servo motor 81 is periodically controlled to start, and the output end of the servo motor 81 drives the transmission gear 9 to rotate. For the convenience of description, the present invention is illustrated by an example. Combining with the attached Figure 3 As shown, assuming that the servo motor 81 rotates clockwise, the transmission gear 9 rotates synchronously with it to engage with the meshing gear 7, so that the meshing gear 7 rotates counterclockwise. Under the action of the meshing gear 7, the transmission gear 9 rotatably connected to the inner wall of the mounting frame 8 rotates clockwise synchronously. In the initial state, the sliding block 71 on the meshing gear 7 is located in the sliding groove 61, so that the meshing gear 7 drives the sliding shaft body 6 to rotate synchronously, and the sliding shaft body 6 is slidably connected to the impregnation barrel 3. Therefore, the sliding shaft body 6 drives the impregnation barrel 3 to rotate during the rotation process, that is, the impregnation barrel 3 rotates in the metal barrel body 2; Combining with the attached Figure 3As shown, when the impregnation bucket 3 rotates counterclockwise, the internal metal partition 31 acts on the cashmere, causing some of the cashmere to leave the auxiliary agent. Subsequently, the servo motor 81 stops starting, causing the clamping shaft body 65 to coincide with the clamping hole 83. It should be noted that the rotation angle of the impregnation bucket 3 can be set during the actual working process to ensure that after each clockwise and counterclockwise rotation of the impregnation bucket 3, there is a period when the cashmere soaked in the impregnation bucket 3 leaves the auxiliary agent, that is, the cashmere soaked in the auxiliary agent is divided into two equal parts. When the impregnation bucket 3 rotates clockwise, the first part of the cashmere leaves the auxiliary agent. When the impregnation bucket 3 rotates counterclockwise, the second part of the cashmere leaves the auxiliary agent. Then, after the servo motor 81 stops starting, the electromagnetic component 84 is controlled to be energized. The electromagnetic component 84 is energized to generate an attractive force on the magnetic plate frame 64, so that under the action of the magnetic plate frame 64, the clamping shaft body 65 enters the clamping hole 83. When the clamping shaft body 65 enters the clamping hole 83, the sliding block body 71 on the meshing gear 7 then enters the annular groove body 62 from the sliding groove body 61. Then, when the meshing gear 7 rotates, the sliding shaft body 6 will not rotate with the meshing gear 7, causing the impregnation bucket 3 to be in a stationary state. Subsequently, the servo motor 81 starts again, and the transmission gear 9 rotates with the output end of the servo motor 81. The transmission gear 9 connected to the output end of the servo motor 81, and the corresponding annular disc frame 101 thereof drives the force-bearing shaft body 107 to drive the force-bearing disc frame 105 to rotate forward through the fixed seat body 102 and the acting rod frame 103. At this time, the variable torque spring 106 deforms, combined with Attachment Figure 11 As shown in Figure a in During the forward rotation of the force-bearing disc frame 105, the force-bearing disc frame 105 drives the square frame 51 to move synchronously through the connecting rod frame 5. The connecting shaft body 52 in the square frame 51 rotates forward. Since one end of the connecting shaft body 52 is a magnetic end, during the forward rotation of the connecting shaft body 52, the magnetic part 42 exerts a repulsive force on the magnetic end of the connecting shaft body 52, and the connecting shaft body 52 squeezes the return spring 43. At the same time, the connecting shaft body 52 drives the pressing part 54 to squeeze the cashmere that has left the auxiliary agent under the action of the fixed plate frame 53, combined with Attachment Figure 13As shown, during the forward rotation of the square frame 51, the annular baffle 57 will not block the magnetic end of the connecting shaft body 52. Therefore, during the forward rotation of the connecting shaft body 52, the magnetic end at its end will be subjected to the repulsive force of the magnetic part 42. When the square frame 51 rotates forward to the end, that is, when the acting rod frame 103 moves to the area where it is about to separate from the stressed shaft body 107, the driving rod frame 59 on the rotating shaft body 58 will be affected by one of the force - applying rod frames 44. Then, the driving rod frame 59 drives the rotating shaft body 58 to rotate, so that the annular baffle 57 blocks the magnetic end of the connecting shaft body 52. Thus, when the stressed disc frame 105 rotates reversely under the action of the variable - torque spring 106, the connecting rod frame 5 will drive the square frame 51 to rotate reversely. At this time, since the magnetic end of the connecting shaft body 52 is blocked by the annular baffle 57, the connecting shaft body 52 will not be subjected to the repulsive force of the magnetic part 42. That is, under the action of the return spring 43, the fixed - plate frame 53 drives the pressing part 54 to leave the area where it applies force to the cashmere. That is, during the reverse rotation of the pressing part 54, the cashmere will not be affected by the pressing part 54. When the rotating shaft body 58 rotates reversely to near the initial position, the driving rod frame 59 on it will be affected by another force - applying rod frame 44, causing the annular baffle 57 to rotate again, that is, the annular baffle 57 will not block the magnetic end of the connecting shaft body 52. Therefore, through the design of the present invention, during the forward rotation of the square frame 51 (i.e., the stressed disc frame 105 rotates synchronously with the annular disc frame 101), the pressing part 54 presses the cashmere; during the reverse rotation of the square frame 51 (i.e., the stressed disc frame 105 rotates in the opposite direction to the annular disc frame 101), the pressing part 54 will not press the cashmere. By indirectly pressing the cashmere, on the one hand, it can avoid the situation of oversaturated accumulation of the auxiliary agent on the fiber surface caused by continuous pressing. On the other hand, intermittent pressing facilitates the relaxation and rebound of the fiber molecular chains, enabling the fibers to naturally adjust the distribution of the auxiliary agent through capillary action, promoting the penetration and uniform distribution of the auxiliary agent. And regular pressing and re - soaking can make the distribution of the auxiliary agent more uniform, avoiding too high or too low local concentration.
