Description

Technical Field

[0001] The present invention relates to the technical field of blended alpaca wool and cashmere, and specifically to a preparation process for worsted blended alpaca wool and cashmere fibers and an alpaca wool pretreatment device. Background Art

[0002] Alpaca wool yarn is a very high-quality wool yarn. When blended with cashmere fiber known as "soft gold in fibers", its grade is improved, the texture is softer, and it is suitable for making winter clothes and accessories. Its fiber is soft, has good spinning effect, anti-wrinkle and anti-shrinkage characteristics, making it the best choice for manufacturing high-quality woolen fabrics. It can be used to make fleece coats, dresses, cardigans, etc. The clothes are light, soft, comfortable to wear, and have no stinging feeling. According to the production process, alpaca cashmere yarn is divided into three categories: woolen-spun alpaca cashmere yarn, worsted-spun alpaca cashmere yarn, and semi-worsted-spun alpaca cashmere yarn. Among them, worsted-spun alpaca cashmere yarn is the highest-grade one. In the process of preparing blended alpaca wool and cashmere fibers, first, alpaca wool needs to be pretreated, and then alpaca wool and cashmere are spun. During the process, the mixed fibers are processed into continuous and uniform strip semi-finished products by a carding machine. In this process, the mixed fibers are subjected to rough carding and fine carding processes by the carding machine, and then the doubling work is carried out, that is, through multiple doubling and drafting, the uniformity of fiber arrangement is gradually improved, and multiple gilling processes are carried out through multiple sets of needle plates. After the treatment is completed, processes such as woolen spinning, spinning, winding, doubling, doubling twisting, and rewinding are carried out; due to the poor spinnability of alpaca wool, static electricity is likely to occur in the gilling process, increasing the production difficulty. In order to reduce the impact of static electricity on alpaca wool spinning, alpaca wool is usually transported to a humidifying room before spinning, and an antistatic agent is sprayed on the surface of alpaca wool to remove static electricity from alpaca wool through the antistatic agent. However, in the actual treatment process, due to the scale-layer structure of alpaca wool fibers, the closed scale layer will hinder the penetration of the antistatic agent, and the penetration depth usually decreases by about 40%, resulting in uneven penetration of alpaca wool, which is likely to affect the subsequent blending process. Therefore, we propose a preparation process for worsted blended alpaca wool and cashmere fibers and an alpaca wool pretreatment device. Summary of the Invention

Specific embodiments

[0017] 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.

[0018] Please refer to Figures 1-11 , the present invention provides a technical solution: a preparation process for worsted alpaca wool and cashmere blended fibers and an alpaca wool pretreatment device, including the following steps: a. Raw material treatment: Wash and degrease alpaca wool and cashmere, and perform a sorting process on alpaca wool and cashmere; b. Alpaca wool pretreatment: transport the alpaca wool into a humidifying chamber, spray 1% of an antistatic agent on the surface of the alpaca wool, and leave it for 24 hours after treatment to allow moisture to fully penetrate; in this process, the alpaca wool is treated to improve the penetration rate of the antistatic agent; the humidifying chamber body 1 and a conveying mechanism 2 for conveying the alpaca wool into the humidifying chamber body 1 are provided in sequence in the humidifying chamber body 1 along the conveying direction of the conveying mechanism 2, a combing unit 3 for preventing fiber entanglement, a pressing part 1 4 for expanding the fiber gap, a spraying mechanism 5 for spraying an antistatic agent on the surface of the alpaca wool, an auxiliary penetration unit 6 for assisting the penetration of the antistatic agent by combing the alpaca wool, and a pressing part 2 7 for inhibiting fiber rebound; c. Needle combing: In the first mixing process, according to the proportion of ingredients, 3 alpaca wool strips + 2 cashmere strips are used for the first stitch of sliver making, and the drafting is 5 times, the gauge is 45-50mm, and the second stitch of sliver making is in the ratio of "1:1:12", the oil nozzle diameter is 0.65, and after adding oil and water, it is left for 12 hours before being put on the machine for the next process; d. Combing: Choose the combing machine gauge reasonably, increase the density of the circular comb pin plate to remove fine cotton particles, and use small merging, small drafting, low speed and small feeding to process the mixed fiber; e. Recombing: Recombing the combed fibers to improve their smoothness; f. Pre-spinning: drawing the alpaca and cashmere mixed fibers, followed by needle combing; g. Roving: The mixed fiber strips after pre-spinning are stretched and thinned, and twisted to form roving; h. Spun yarn: The mixed fibers after roving are further drawn and twisted to form spun yarn with standard fineness and uniform strength; i. Winding, doubling, twisting and rewinding processes: winding the spun yarn into a cone, then combining multiple single yarns into ply yarns to improve uniformity and strength, applying high twist to the ply yarns to enhance yarn strength, wear resistance and gloss, rewinding the yarn, removing residual defects and optimizing the package structure.

[0019] In step b, it is mentioned that the alpaca wool is pretreated. Since the alpaca wool fiber structure is in the form of scale layers, during the process of spraying the antistatic agent thereon, the closed scale layers will hinder the penetration of the antistatic agent, thereby affecting the permeability, resulting in poor antistatic treatment effect of the alpaca wool. In view of this, the present invention uses a pressing method to temporarily flatten the scale layers on the surface of the alpaca wool fiber, so that the fiber gaps are enlarged, thereby effectively reducing the resistance to the penetration of the antistatic agent, and combing the alpaca wool before pressing can effectively reduce the entanglement problem of the alpaca wool fibers, and the entanglement of the alpaca wool will affect the fiber density after pressing, and the uneven density of the fiber layer will cause the antistatic agent to accumulate in the low-density area, and the high-density area will not be sufficiently penetrated; based on this, the present invention performs the following pretreatment work on the alpaca wool: Combined with Figure 3As shown in the figure, as a further limitation in the present invention, both the pressing part one 4 and the pressing part two 7 include a fixed shaft body 8 with both ends fixedly connected to the inner wall of the humidifying chamber body 1. A sliding plate frame 81 is arranged below the fixed shaft body 8. A guiding shaft body 84 slidably connected to the fixed shaft body 8 is symmetrically installed on the sliding plate frame 81. A return spring 85 sleeved on the guiding shaft body 84 and connected to the fixed shaft body 8 is installed on the sliding plate frame 81. An electromagnetic component 83 is fixedly installed on the fixed shaft body 8. The electromagnetic component 83 can generate magnetism when energized. A bar magnet 87 located directly below the electromagnetic component 83 is fixedly installed on the sliding plate frame 81. When the electromagnetic component 83 is energized, a repulsive force will be generated on the bar magnet 87. A pressing panel 82 made of silica gel material is arranged below the sliding plate frame 81. The pressing panel 82 is made of silica gel material mainly to avoid abrasion of the scale layer of alpaca wool. The pressing panel 82 is connected to the sliding plate frame 81 through a telescopic part 86.

[0020] Furthermore, when the pressing part one 4 in the present invention presses the alpaca wool, the pressure exerted by the pressing panel 82 on the alpaca wool is usually designed to be 0.2 - 0.3 MPA. When the pressing part two 7 presses the alpaca wool after spraying the antistatic agent, the pressure exerted by the pressing panel 82 on the (sprayed with antistatic agent) alpaca wool is usually designed to be 0.1 MPA. Therefore, the power-on amount of the electromagnetic component 83 corresponding to the pressing part one 4 is greater than the power-on amount of the electromagnetic component 83 corresponding to the pressing part two 7. The main function of the pressing panel 82 corresponding to the pressing part two 7 when pressing the alpaca wool is to inhibit fiber rebound. Pressing the alpaca wool before spraying the antistatic agent is to facilitate the penetration of the antistatic agent. The pressing after spraying is mainly to press the antistatic agent into the fiber gaps, reduce the proportion of liquid droplets remaining on the surface due to surface tension, and effectively prevent the situation that the antistatic agent is squeezed out of the alpaca wool caused by fiber rebound.

[0021] As a further limitation in the present invention, the combing unit 3 includes a servo motor 31 fixedly installed on the outer wall of the humidifying chamber body 1. A support shaft body 11 is also fixedly installed inside the humidifying chamber body 1. A rotating shaft body 32 is fixedly installed on the support shaft body 11. The rotating shaft body 32 is connected to the output end of the servo motor 31 through a gear mechanism 33. Combined with the attached Figure 4As shown in the figure, the gear mechanism 33 in the present invention is composed of a protective housing, a large gear and a small gear. The small gear is connected to the output end of the servo motor 31, and the large gear is connected to the rotating shaft body 32. A plurality of annular brackets 34 are fixedly installed on the rotating shaft body 32, and the plurality of annular brackets 34 are equidistantly distributed on the rotating shaft body 32. Thus, under the speed-changing action of the gear mechanism 33, the rotation of the rotating shaft body 32 is relatively slow. A plurality of connecting frames 35 are symmetrically installed on each annular bracket 34, and the plurality of connecting frames 35 are annularly and equally angularly distributed on the annular bracket 34. A connecting rod frame 36 slidably connected to its inner wall is installed inside each connecting frame 35. An arc-shaped frame 37 is fixedly installed at the end of the connecting rod frame 36, and an arc-shaped slider 38 slidably connected to its inner wall is installed inside the arc-shaped frame 37. A carding tooth group 39 is fixedly installed on the arc-shaped slider 38. A spring body 30 is connected between the arc-shaped slider 38 and the arc-shaped frame 37, and a constant force spring 301 is connected between the connecting rod frame 36 and the inner wall of the end of the connecting frame 35. The carding tooth group 39 in the present invention is made of silica gel material; A plurality of right-angled triangular clamping blocks 302 are fixedly installed on the connecting rod frame 36. A roller part 303 is arranged inside the connecting frame 35, and the roller part 303 is located on the movement track of the clamping block 302. A penetrating shaft body 304 is fixedly installed on the roller part 303, and the end of the penetrating shaft body 304 penetrates through the inner wall of the connecting frame 35 and extends to the outside thereof. The end of the penetrating shaft body 304 is a magnetic end, and a plastic spring 305 is connected between the penetrating shaft body 304 and the outer wall of the connecting frame 35. It should be noted that the connecting frame 35, the connecting rod frame 36, the arc-shaped frame 37 and the arc-shaped slider 38 in the present invention are preferably made of plastic materials with high strength. A fixing plate frame 306 is fixedly installed on the inner wall of the humidifying chamber body 1, and a plurality of equally spaced extending frame bodies 307 are fixedly installed on the fixing plate frame 306. Combining with the attached Figure 4 As shown in the figure, the extending frame body 307 is not located on the movement track of the arc-shaped frame 37. A circular magnet 308 is fixedly installed on the extending frame body 307. The magnetic pole of the circular magnet 308 is opposite to the magnetic pole of the magnetic end of the penetrating shaft body 304. When the penetrating shaft body 304 rotates through the corresponding position of the circular magnet 308, the circular magnet 308 will be attracted by the penetrating shaft body 304. A plurality of strong magnets 309 are fixedly installed on the annular bracket 34, and the strong magnets 309 correspond to the arc-shaped sliders 38 one by one. A square magnet 300 is fixedly installed on the arc-shaped slider 38. The magnetic poles of the strong magnet 309 and the square magnet 300 are opposite, and the strong magnet 309 is located on the movement track of the square magnet 300.

[0022] As a further limitation in the present invention, the auxiliary penetration unit 6 includes a power motor 61 fixedly installed on the outer wall of the humidification chamber body 1. Inside the humidification chamber body 1, an annular gear set 62 rotatably connected to its inner wall is also installed. The annular gear set 62 is fixedly connected to the output end of the power motor 61. On the tooth surface of the annular gear set 62, a plurality of V-shaped micro-grooves 621 with a gradient pitch are provided. The gradient pitch setting means that the pitch of the V-shaped micro-grooves 621 gradually decreases from the root to the tip of the tooth. The gradient pitch design of the V-shaped micro-grooves 621 can make the curvature radius of the antistatic agent droplets in the V-shaped micro-grooves 621 change gradually, thereby generating a capillary pressure difference to drive the antistatic agent to flow from the low-curvature (i.e., large pitch) area to the high-curvature (small pitch) area. The antistatic agent droplets are driven by the pressure difference in the grooves with a gradient pitch and migrate from the low capillary force at the tooth root to the high capillary force at the tip, and finally flow back to the fiber layer. To facilitate the flow of the antistatic agent in the V-shaped micro-grooves 621, a hydrophobic coating can be applied to the surface of the teeth and the V-shaped micro-grooves 621. Then, after spraying the antistatic agent, the alpaca wool is combed. During the combing process, the friction and extrusion between the teeth on the annular gear set 62 and the fibers will temporarily open and close the scale layer on the fiber surface, forming micron-level gaps, which is convenient for the antistatic agent to penetrate deep into the fiber interior through capillary action. It should be noted that in order to show that the teeth on the combing gear set 39 and the annular gear set 62 are arc-shaped, the angle of the teeth in the present invention is magnified. In the actual application process, the angle of the teeth needs to be adjusted.

[0023] Specifically, as shown in the attached Figures 1-3 figure, first, the staff evenly spreads the alpaca wool on the conveying mechanism 2. Under the action of the conveying mechanism 2, the alpaca wool enters the humidification chamber for humidification treatment. The humidification treatment is beneficial to the penetration of the antistatic agent. During the conveying process, the alpaca wool on the conveying mechanism 2 first passes through the combing gear set 39 (as shown in the attached Figure 3As shown, during this process, the servo motor 31 starts, and its output end drives the rotating shaft body 32 to rotate directionally on the support shaft body 11 through the gear mechanism 33, so that multiple annular brackets 34 on the rotating shaft body 32 rotate synchronously. The annular brackets 34 drive the arc-shaped frame 37 to rotate synchronously through the connecting frame 35 and the connecting rod frame 36. The arc-shaped slider 38 in the arc-shaped frame 37 drives the carding tooth group 39 to card the alpaca wool. Under normal conditions, the tips of the carding tooth group 39 penetrate into the bottom of the alpaca wool. If there is no fiber entanglement in the alpaca wool, the carding tooth group 39 cards the alpaca wool. When there is fiber entanglement in the alpaca wool, the teeth on the carding tooth group 39 will be blocked by the entangled fibers of the alpaca wool, and then the carding tooth group 39 drives the arc-shaped slider 38 to squeeze the spring body 30. It should be noted that the spring body 30 needs to select a spring with a relatively small elastic coefficient, and the rotating shaft body 32 rotates relatively slowly under the speed-changing action of the gear mechanism 33. Therefore, the carding tooth group 39 will not damage the fibers when contacting the entangled fibers. Combined with the appendix Figure 6 As shown, during the movement of the arc-shaped slider 38 in the arc-shaped frame 37, the square magnet 300 on the arc-shaped slider 38 will move to directly below the strong magnet 309. At this time, the strong magnet 309 will generate an attractive force on the square magnet 300. Then, under the action of the square magnet 300, the arc-shaped slider 38 drives the arc-shaped frame 37 to move towards the strong magnet 309, that is, the connecting rod frame 36 moves directionally in the connecting frame 35 and squeezes the constant force spring 301 during the movement; Combined with the appendix Figure 7As shown, during the movement of the connecting rod frame 36 into the interior of the connecting frame 35, the right-angled triangular clamping block 302 on the connecting rod frame 36 will exert a force on the roller part 303. Since the inclined surface of the clamping block 302 exerts a force on the roller part 303 during the upward movement, the roller part 303 will move towards the side wall of the connecting frame 35 under the action of the force, that is, the through shaft 304 stretches the plastic spring 305. At this time, the connecting rod frame 36 can move upward in a fixed direction. Then, the arc-shaped slider 38 drives the carding tooth group 39 and the arc-shaped frame 37 to move upward, that is, the carding tooth group 39 leaves the alpaca wool. After the carding tooth group 39 leaves the alpaca wool, the arc-shaped slider 38 will return to its initial position under the action of the spring body 30, that is, the square magnet 300 no longer receives the attraction of the strong magnet 309, and the compressed constant force spring 301 will exert a reaction force on the connecting rod frame 36. However, since the right-angled surface of the clamping block 302 is blocked by the roller part 303, the connecting rod frame 36 cannot move downward. During the rotation of the rotating shaft body 32, the magnetic end of the through shaft 304 will pass through the corresponding position of the circular magnet. During this process, the circular magnet will generate an attractive force on the magnetic end of the through shaft 304, and the roller part 303 will briefly leave the movement track of the clamping block 302, so that the connecting rod frame 36 performs a reset movement. During the reset process, the through shaft 304 will return to its initial position, that is, the roller part 303 will again hinder the reset of the connecting rod frame 36. In the present invention, every time the through shaft 304 passes through the corresponding position of the circular magnet, the clamping block 302 in contact with the roller part 303 changes once, so that the carding tooth group 39 resets with the number of rotations of the rotating shaft body 32. Referring to the attached Figure 6 and the attached Figure 7 As shown, when there is a fiber entanglement condition in the alpaca wool, the carding tooth group 39 will first leave the alpaca wool, and then during the rotation of the rotating shaft body 32, the fiber-entangled alpaca wool will be carded layer by layer. The layer-by-layer carding in the present invention means: gradually processing the alpaca wool from the surface to the bottom in sequence, so that the alpaca wool can be effectively carded by multiple carding tooth groups 39 to reduce the fiber entanglement rate of the alpaca wool; After combing, the alpaca wool will move to the lower part of the pressing panel 82 of the first pressing part 4. The electromagnetic component 83 corresponding to the first pressing part 4 is electrified to generate a repulsive force on the bar magnet 87, so that the sliding plate frame 81 drives the pressing part to press the alpaca wool under the action of the guiding shaft body 84 through the telescopic part 86. The scale layer on the surface of the alpaca wool fiber can be temporarily flattened, the fiber gap can be enlarged, and thus the resistance during the penetration of the antistatic agent can be effectively reduced. Through pressing, the difference in fiber packing density can be effectively reduced, and the droplets can be prevented from staying on the surface due to the electrostatic shielding effect during spraying. After pressing, the alpaca wool will move to the spraying mechanism 5. The spraying mechanism 5 sprays the antistatic agent on the surface of the alpaca wool. After combing and pressing, the fiber gap of the alpaca wool is enlarged to facilitate the penetration of the antistatic agent. After the spraying of the antistatic agent is completed, it will move to the lower part of the annular tooth group 62, and the annular tooth group 62 is used to facilitate the penetration of the antistatic agent into the fiber interior along the gap by capillary action. Subsequently, when passing under the pressing panel 82 of the second pressing part 7, the electromagnetic component 83 corresponding to the second pressing part 7 is electrified, so that the pressing panel 82 of the second pressing part 7 presses the alpaca wool again (at this time, the power-on amount of the electromagnetic component 83 corresponding to the second pressing part 7 should be less than the power-on amount of the electromagnetic component 83 corresponding to the first pressing part 4). Through the repeated pressing of this pressing panel 82, the antistatic agent can be pressed into the fiber gap, and at the same time, the situation that the antistatic agent is squeezed out due to the fiber rebound can be effectively prevented. Furthermore, through the structural design of the present invention, the pretreatment quality of the alpaca wool can be effectively improved, so as to improve the quality of the blended fiber during the preparation of the blended fiber of alpaca wool and cashmere.
