Description

Technical Field

[0001] The present invention relates to the technical field of textile devices, and in particular to a basalt fiber for clothing and an omnidirectional sizing device and method thereof. Background Art

[0002] Basalt fiber is a continuous fiber drawn from natural basalt. As a new type of inorganic, environmentally friendly, green, high-performance fiber material, it is composed of oxides such as silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide, iron oxide and titanium dioxide. Basalt fiber not only has high strength, but also has many excellent properties such as electrical insulation, corrosion resistance, and high temperature resistance. Therefore, it is widely used in fiber-reinforced composite materials, friction materials, shipbuilding materials, thermal insulation materials, the automotive industry, high-temperature filter fabrics, and protective fields. In addition, clothing made from basalt fiber has the advantages of flame retardancy, thermal insulation, electrical insulation, and corrosion resistance, and can be used to prepare functional clothing such as fire suits, welding suits, and electrician suits. However, the following disadvantages are faced when applying basalt fiber in the clothing field:

[0003] ① Poor comfort: Although basalt fiber has high strength, it has poor toughness and is prone to breakage during production and long-term use. After breaking, the ends of the basalt fiber are hard and the fracture surface is sharp, which causes an itchy sensation when in contact with the human body, resulting in poor comfort of the fabric. ② Difficult to dye: Basalt fiber is an inorganic fiber and lacks functional groups on its surface that can bind to dyes. Therefore, it cannot be dyed with chemical dyes that can react with it. In addition, the molecular structure of basalt fiber is stable and difficult to loosen under high temperature and high pressure environments. Therefore, it cannot be dyed by dye penetration. As a result, basalt fiber fabrics have a single color and cannot meet the demand for color diversity in clothing. ③ Poor hygroscopicity: Basalt fiber has relatively poor hygroscopicity, far inferior to natural fibers such as cotton. This may make clothing made of basalt fiber difficult to maintain comfort in hot and humid environments. ④ Average wear resistance: Although basalt fiber has good strength and durability, its wear resistance is relatively poor. This means that basalt fiber clothing may wear and fall off due to long-term friction.

[0004] The aforementioned problems with basalt fiber in the clothing industry have restricted its development. Therefore, coating the fiber surface with a layer of functional material (known as sizing in the textile field) is one of the most effective ways to address these issues.

[0005] In the prior art, an invention patent (application number CN202211050591.4) discloses a continuous basalt fiber dyeing device and manufacturing method that is convenient for dipping and sizing. The dyeing device includes a dye tank, a dyeing roller, an adjustable movable seat, an adjustable slider, and a support structure. The device ensures continuous and stable dipping and sizing operations, and cooperates with the double adjustment at the adjustable movable block to facilitate the basalt fiber to maintain a good immersion effect and avoid loosening caused by insufficient tension that affects stable dipping and sizing. However, this method is to immerse the bundled tow into a slurry tank for sizing. Therefore, the fibers after sizing are prone to sticking, causing the basalt fibers to become hard as a whole, reducing their performance in clothing. In addition, the fiber sizing amount after sizing is high, and the fiber weight increases significantly, resulting in a large weight per unit area of the fabric, which is difficult to apply to the clothing field.

[0006] The utility model patent (application number CN201920699328.5) discloses a multifunctional sizing device for basalt fiber, which includes an electrical control cabinet, a motor-driven yarn unwinding frame, an ultrasonic desizing tank, a sizing tank, a sensor, an oven, an immersion roller, a drive, and a winding device. This patent has both desizing and sizing functions, and can simultaneously unwind multiple rolls of fibers, achieving simultaneous desizing and sizing of different types of fibers, thereby obtaining mixed multifilaments of different types of fibers. However, this method uses a similar sizing method as the invention patent CN 202211050591.4, and has the same shortcomings, and neither solves the shortcomings of basalt fiber in the field of clothing.

[0007] The invention patent (application number 202010688364.9) discloses a high-performance sizing machine and a processing method thereof, wherein the sizing machine includes a machine body, a yarn feed roller assembly for feeding yarn, and a sizing assembly for sizing the yarn, which is sequentially provided on the machine body along the moving direction of the yarn, and the machine body is provided with a first spray pipe for sizing the yarn between the first pressing roller and the sizing roller, and the slurry delivery pipe connected to the first spray pipe is provided with a first pneumatic booster pump to improve the sizing efficiency of the yarn. However, the sizing machine is provided with multiple spray mechanisms and booster pumps corresponding to each spray mechanism, so that the yarn is sized at three points to ensure the uniformity and efficiency of sizing, which increases the complexity of the yarn sizing process and device, thereby increasing the yarn sizing cost and the difficulty of maintenance of the device, and making it difficult to carry out industrial batch sizing of yarn.

[0008] In view of this, it is necessary to design an improved basalt fiber for clothing and an all-round sizing device and method thereof to solve the above problems. Summary of the Invention

The blocking plates are tangent to the outer surface of the limiting roller, forming a cavity between the covering layer and the movable roller, so that the slurry is temporarily placed in the cavity.

[0017] As a further improvement of the present invention, the coating layer is provided with a feed port, and the feed port is connected to a slurry guide pipe to achieve continuous input of slurry.

[0018] As a further improvement of the present invention, the distance between the two limiting rollers and the transmission shaft is 1 to 5 cm, so as to limit the axial reciprocating movement range of the movable roller relative to the transmission assembly.

[0019] As a further improvement of the present invention, the sizing device also includes a yarn guide roller, a transition roller and a lead-out roller arranged along the conveying direction of the basalt fiber, the sizing roller group is arranged between the yarn guide roller and the transition roller, and the yarn guide roller, transition roller and lead-out roller are all fixedly connected to the frame.

[0020] As a further improvement of the present invention, the sizing device also includes a slurry storage tank arranged below the sizing roller group and the transition roller.

[0021] As a further improvement of the present invention, a soft rubber layer is provided on the surface of the movable roller to achieve clamping and sizing of the basalt fiber; a drying component is provided between the transition roller and the lead-out roller to achieve drying of the sized basalt fiber.

[0022] The present invention also provides a method for sizing basalt fibers for clothing in an all-round manner, wherein sizing is performed using any one of the above-described omnidirectional sizing devices for basalt fibers for clothing, and the specific steps are as follows:

[0023] The batch of basalt fibers to be sized is transported by the yarn guide roller to the sizing roller group, passes between the two sizing rollers of the sizing roller group, and the adjustment component drives the two movable rollers to rotate in the same direction as the basalt fiber conveying, bringing out the slurry contained in the cavity between the wrapping layer and the movable roller, and sizing the basalt fibers passing through; at the same time, the power component drives the two movable rollers to move axially back and forth, kneading the basalt fibers, so that the basalt fibers rotate and achieve all-round sizing; the sizing basalt fibers are filtered by the transition roller, dried by the drying component, and finally discharged by the discharge roller.

[0026] The present invention also provides a basalt fiber for clothing prepared by the above-mentioned omnidirectional sizing method for basalt fiber for clothing, wherein each fiber surface of the basalt fiber for clothing is evenly loaded with a sizing layer, and the thickness of the sizing layer is 1 to 5 μm, so that the diameter of the basalt fiber for clothing after sizing is 8 to 30 μm.

[0027] The beneficial effects of the present invention are:

[0028] 1. The present invention provides a basalt fiber for apparel and a device and method for sizing the same. The sizing device comprises a sizing roller assembly, which differs from existing sizing machines. The sizing roller assembly includes two opposing and parallel sizing rollers, each comprising a transmission assembly, a movable roller sleeved on the surface of the transmission assembly, and a coating covering the movable roller and the transmission assembly. The transmission assembly is connected at both ends to an adjustment assembly and a power assembly, respectively. The power assembly drives the movable roller to axially reciprocate via the transmission assembly, and the adjustment assembly drives the movable roller to rotate via the transmission assembly. When the sizing device of the present invention is used, the movable roller is used to clamp and convey the basalt fiber. During the rotation of the movable roller, the sizing material in the cavity is removed to sizing the basalt fiber. Simultaneously, the axial reciprocating movement of the movable roller drives the basalt fiber to rotate and knead the basalt fiber. This achieves omnidirectional sizing of the basalt fiber, improves the uniformity of the sizing of the basalt fiber, and controls the amount of sizing applied to the basalt fiber, thereby avoiding the problem of excessive sizing increasing the fiber's hardness, which is unfavorable for its application in the apparel field.

[0029] 2. The sizing roller of the present invention is provided with a three-layer structure of a transmission component, a moving roller and a coating layer. The transmission component is respectively connected to the adjustment component and the power component, and is fixedly connected to the moving roller, playing the role of transmitting power, so that the moving roller can not only rotate, but also perform axial reciprocating movement, thereby driving the basalt fiber to rotate during the sizing process, kneading the basalt fiber, and improving the uniformity of sizing of the basalt fiber. The coating layer is provided with an opening structure, and by providing a blocking sheet, a cavity for accommodating the slurry is formed between the moving roller and the coating layer, so that the slurry follows the rotation and movement of the moving roller to achieve sizing of the basalt fiber, which not only improves the sizing effect, but also avoids the waste of slurry. The present invention improves the efficiency and uniformity of sizing of basalt fibers through the coordinated cooperation of the three-layer structure of the sizing roller, and can still maintain a good sizing effect on basalt fibers after brittle fracture, so that they will not hurt the body after being applied to the field of clothing, thereby improving comfort.

[0030] 3. This invention delivers basalt fibers to the sizing roller assembly in a uniform arrangement of individual fibers. Sizing is performed during the basalt fiber conveying process, ensuring that the fibers remain dispersed after sizing, preventing adhesion. This improves sizing effectiveness and overcomes the problem of basalt fiber strand accumulation, entanglement, and knotting that often occurs during traditional immersion sizing. This sizing device can sizing batches of basalt fibers, improving sizing efficiency and making it suitable for industrial mass production.

[0031] 4. The present invention adjusts the distance between the guide rods connecting the two transmission assemblies through the movable connecting piece of the adjustment assembly, thereby adjusting the spacing between the two movable rollers, so that the rollers exert appropriate pressure on the clamped basalt fibers. The movable rollers can knead the basalt fibers when they move horizontally without causing the basalt fibers to shift excessively, ensuring that the sizing basalt fibers remain dispersed and do not adhere to each other. The distance between the movable rollers can also be used to control the liquid carrying rate of the basalt fibers, avoiding the load of excess slurry on the surface of the basalt fibers, thereby increasing pressure on the transportation of basalt fibers and their application in the clothing field.

[0032] 5. The sizing device of the present invention has a simple structure and can be used in conjunction with a factory's basalt fiber manufacturing equipment to achieve continuous preparation and sizing of basalt fiber, reducing costs and achieving high economic benefits. Furthermore, the sizing device and method of the present invention allow for the addition of coloring materials to the slurry to color the basalt fiber, increasing its versatility as a fiber for clothing and overcoming the existing issues of basalt fiber being difficult to color and having a single color.

[0041] It should also be noted here that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the solutions of the present invention are shown in the drawings, while other details that are not closely related to the present invention are omitted.

[0042] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0043] Example 1

[0044] See also Figure 1As shown, an all-round sizing device 100 for basalt fiber for clothing includes a frame, a sizing roller group 110, an adjustment component 120 fixedly connected to the frame, and a power component 130. The sizing roller group 110 includes two sizing rollers arranged opposite and parallel to each other, and the sizing rollers include a transmission component 111, a moving roller 112 sleeved on the surface of the transmission component 111, and a covering layer 113 wrapping the moving roller 112 and the transmission component 111; the two ends of the transmission component 111 are respectively connected to the adjustment component 120 and the power component 130, the power component 130 drives the moving roller 112 to axially reciprocate through the transmission component 111, and the adjustment component 140 drives the moving roller 112 to rotate through the transmission component 111. When the sizing device of the present invention is used, the movable roller 112 is used to clamp and convey the basalt fiber S1. During the rotation of the movable roller 112, the slurry contained in the sizing roller is brought out to size the basalt fiber S1. At the same time, the movable roller 112 performs axial reciprocating movement to drive the basalt fiber S1 to rotate, thereby achieving all-round sizing of the basalt fiber S1 and improving the uniformity of the sizing of the basalt fiber S1. It also controls the sizing amount of the basalt fiber S1, avoiding the problem that the hardness of the fiber is increased due to excessive slurry, which is not conducive to its application in the field of clothing.

[0045] Specifically, the wrapping layer 113 is a tubular structure with an opening on the surface. The openings of the wrapping layers 113 of the two sizing rollers are arranged relative to each other, and the basalt fiber S1 is clamped by the surfaces of the moving rollers 112 exposed at the two openings; a cavity 114 is formed between the wrapping layer 113 and the moving roller 112 for holding the slurry. The slurry is taken out from the opening when the moving roller 112 rotates, and the moving roller 112 moves axially back and forth at the same time, sizing the clamped basalt fiber S1 in all directions. In this way, a three-layer structure of a transmission component 111, a moving roller 112 and a wrapping layer 113 is set by the sizing roller. The transmission component 111 is connected to the adjustment component 120 and the power component 130 respectively, and is fixedly connected to the moving roller 112 to play the role of transmitting power, so that the moving roller 112 can not only rotate, but also move axially back and forth, thereby driving the basalt fiber S1 to rotate during the sizing process, kneading the basalt fiber S1, and improving the uniformity of the sizing of the basalt fiber S1.

[0046] Specifically, the adjustment component 120 includes two meshing gears 121 and a controller for controlling the rotation of the gears 121. The gears 121 are connected to the frame through a fixed component; the two gears 121 are respectively connected to the transmission components 111 of the two sizing rollers through the first guide rod 122 and the second guide rod 124 to control the rotation of the transmission component 111, thereby driving the movable roller 112 to rotate; a movable connecting member 123 is provided between the first guide rod 122 and the second guide rod 124 to realize the movable connection of the two guide rods and the adjustment of the distance between the two sizing rollers. In this way, the distance between the guide rods 122 connecting the two transmission assemblies 11 is adjusted by adjusting the movable connecting piece 123 of the adjustment component 120, thereby adjusting the spacing between the two movable rollers 112 so that the two movable rollers 112 exert appropriate pressure on the clamped basalt fiber S1. When the movable roller 112 moves horizontally, the basalt fiber S1 can be driven to rotate without causing the basalt fiber S1 to shift too much, thereby ensuring that the basalt fibers S1 after sizing remain dispersed from each other and do not adhere to each other; the liquid carrying rate of the basalt fiber S1 can also be controlled by the distance between the movable rollers 112, so that the weight gain percentage of the basalt fiber S1 after sizing is maintained between 15% and 35%, thereby avoiding the surface of the basalt fiber S1 being loaded with excess slurry and increasing the pressure for the transportation of the basalt fiber S1.

[0047] The power assembly 130 includes a motor 131 fixedly connected to the frame, two movable arms 132 connected to the motor 131, and the two movable arms 132 are respectively connected to the transmission assemblies 111 of the two sizing rollers through the third guide rod 133. The motor 131 controls the transmission assembly 111 to move left and right through the movable arms 132 and the third guide rod 133, thereby realizing the axial reciprocating movement of the movable roller 112.

[0048] See also Figure 3 As shown, the transmission assembly 111 includes a transmission shaft 1111 and two limiting rollers 1112 located on the left and right sides of the transmission shaft 1111, and the two limiting rollers 1112 are in a non-contact relationship with the transmission shaft 1111; the outer diameters of the transmission shaft 1111 and the limiting rollers 1112 are consistent in size, and both are clearance-matched with the inner diameter of the moving roller 112; a clamping assembly is provided between the transmission shaft 1111 and the moving roller 112 to achieve fixation of the two; the transmission shaft 1111 is fixedly connected to the end of the second guide rod 124, and the gear 121 drives the second guide rod 124 to rotate and drive the transmission shaft 1111 to rotate, and the transmission shaft 1111 is fixedly connected to the end of the third guide rod 133, and the motor 131 drives the transmission shaft 1111 to move between the two limiting rollers 1112 through the third guide rod 133 to achieve rotation and axial reciprocating movement of the moving roller 112.

[0049] like Figure 3As shown, in some specific embodiments, the transmission shaft 1111 is fixedly connected to the end of the second guide rod 124 by means of a snap connection, and the snap groove is preferably configured as a polygonal structure to prevent rotation between the transmission shaft 1111 and the second guide rod 124. The transmission shaft 1111 is fixedly connected to the end of the third guide rod 133 by means of screws.

[0050] In some specific embodiments, the distance between the two limiting rollers 1112 and the transmission shaft 1111 is 1 to 5 cm, so as to limit the axial reciprocating movement range of the movable roller 112 relative to the transmission assembly 111 .

[0051] See also Figure 2 As shown, the length of the covering layer 113 is greater than that of the moving roller 112, and radial blocking pieces 115 are provided at both ends of the covering layer 113. The blocking pieces 115 are tangential to the outer surface of the limiting roller 1112, forming a cavity 114 between the covering layer 113 and the moving roller 112, so that the slurry is temporarily contained in the cavity 114. In this way, the covering layer 113 is provided with an opening structure, and by providing the blocking pieces 114, a cavity 114 for accommodating the slurry is formed between the moving roller 112 and the covering layer 113, so that the slurry follows the rotation and movement of the moving roller 112 to achieve sizing of the basalt fiber S1, which not only improves the sizing effect but also avoids slurry waste.

[0052] In some specific embodiments, the coating layer 113 is provided with a feed port, which is connected to a slurry pipe to achieve continuous slurry input. The omnidirectional sizing device 100 of the present invention can achieve omnidirectional sizing of the basalt fiber S1 without the need for a spraying port or repeated spraying of the basalt fiber S1.

[0053] The omnidirectional sizing device 100 for basalt fiber for apparel also includes a guide roller 140, a transition roller 150, and a lead-out roller 160 arranged along the conveying direction of the basalt fiber S1. The sizing roller assembly 110 is positioned between the guide roller 140 and the transition roller 150. The guide roller 110, the transition roller, and the lead-out roller 140 are all fixedly connected to the frame. The device also includes a sizing tank located below the sizing roller assembly 110 and the transition roller 150. The sizing tank collects excess sizing material that falls from the sizing roller assembly 110 and the transition roller 150 and returns it to the sizing pipe, thus avoiding sizing waste.

[0054] In some other embodiments, a soft rubber layer is provided on the surface of the moving roller 112 to achieve clamping and sizing of the basalt fiber S1.

[0055] In some other embodiments, a drying assembly is provided between the transition roller 150 and the outlet roller 160 to dry the sized basalt fibers S1.

[0056] A method for sizing basalt fibers for clothing is disclosed, wherein the sizing is performed using an omnidirectional sizing device 100 for basalt fibers for clothing. The specific steps are as follows:

[0057] The batch of basalt fibers S1 to be sized is transported to the sizing roller group 110 by the yarn guide roller 140, passes between the two sizing rollers of the sizing roller group 110, and is driven by the adjustment component 120 to rotate in the same direction as the basalt fiber S1 is transported, bringing out the slurry contained in the cavity 114 between the wrapping layer 113 and the moving roller 112, and sizing the basalt fibers S1 passing through; at the same time, the power component 130 drives the two moving rollers 112 to move axially back and forth, kneading the basalt fibers S1, so that the basalt fibers S1 rotate and achieve all-round sizing; the sizing basalt fibers are filtered by the transition roller 150, dried by the drying component, and finally discharged by the discharge roller 160.

[0058] Specifically, the batch of basalt fibers is delivered to the sizing roller group in a manner of uniformly arranging several single fibers. The spacing between the basalt fibers S1 is 0.5 to 10 mm, providing conditions for sizing them in all directions. The diameter of the basalt fibers S1 is 6 to 20 μm. In this way, the basalt fibers S1 are delivered to the sizing roller group in a manner of uniformly arranging several single fibers. The sizing is performed during the delivery of the basalt fibers S1, so that the basalt fibers remain dispersed after sizing and after forming fiber bundles, and do not adhere to each other. Figure 4 As shown, the sizing effect is improved, overcoming the problems of basalt fiber accumulation, entanglement and knotting during soaking and sizing, waste of sizing material (the weight gain percentage of basalt fiber after sizing is 50% to 70%), and difficulty in controlling the sizing effect. The sizing device can also sizing basalt fibers in batches, improving sizing efficiency and being suitable for industrial mass production.

[0059] In some other embodiments, the slurry is a thermoplastic slurry.

[0060] In some other embodiments, the slurry contains a coloring material, and the basalt fiber is colored while being sizing.

[0061] A basalt fiber for clothing is prepared by the above-mentioned all-round sizing method for basalt fiber for clothing. The surface of each fiber of the basalt fiber for clothing is evenly loaded with a sizing layer, and the thickness of the sizing layer is 1 to 5 μm. The diameter of the basalt fiber for clothing after sizing is 8 to 30 μm. The sizing effect of the basalt fiber after sizing is good and there is no unevenness.

[0062] In particular, the basalt fiber S1 prepared by the sizing device and method has a sizing layer uniformly coated on the surface of each fiber, and the sizing layer is relatively thin, which can wrap the fiber without increasing the hardness of the fiber; in this way, the sizing basalt fiber S1 is not easy to break, and no sharp fracture will be formed after breaking. The presence of the sizing layer also improves the hygroscopicity and wear resistance of the basalt fiber; and the device can still maintain a good sizing effect on the basalt fiber after brittle fracture, so that it will not hurt the body after being used in the field of clothing, thereby improving comfort, and can be applied to clothing materials, such as fire suits, chemical protective clothing and other fields.

[0063] The sizing device of the present invention has a simple structure and, in practical applications, can be used in conjunction with a factory's basalt fiber manufacturing equipment to achieve continuous preparation and sizing of basalt fiber, reducing costs, resulting in high economic benefits and significant industrial application value. Furthermore, the sizing device and method of the present invention can also be used to add coloring materials to the slurry to color the basalt fiber S1, increasing its versatility as a fiber for clothing and overcoming the existing problem of basalt fiber being difficult to color and having a single color.

[0064] A batch of basalt fibers are sized using the device and method of Example 1 of the present invention. The fiber diagram after sizing is shown in FIG. Figure 4 As shown in the figure, the surface of each basalt fiber is covered with sizing material, indicating that the sizing effect is good and there is no unevenness. Moreover, the basalt fibers after sizing are still dispersed with each other after forming fiber bundles without adhesion. The measurement shows that the weight increase percentage of the yarn after sizing is 29%.

[0065] Comparative Example 1

[0066] Comparative Example 1 provides a sizing device and method for sizing basalt fiber, and adopts the immersion method to size the basalt fiber of the same gram weight as Example 1. After sizing, the basalt fiber is prone to problems such as strand accumulation, entanglement and knotting. Figure 5 As shown, the sizing effect is uncontrollable and uneven. After sizing, the basalt fibers stick together, making it difficult to measure the average diameter of a single fiber. After measurement, it was found that the weight gain percentage of the basalt fibers after sizing was 65%.

[0067] Comparative Example 2

[0068] Comparative Example 2 provides a sizing device and method for sizing basalt fibers. This differs from Example 1 in that the power assembly 130 is omitted, meaning that the movable roller 112 cannot reciprocate axially. The remaining steps are generally the same as those in Example 1 and are not described here. After sizing, the basalt fibers changed from a regular circular shape to an elliptical shape, indicating that the device and method in this comparative example resulted in uneven sizing of the basalt fibers, resulting in poor performance of the elliptical basalt fibers.

[0069] In summary, the present invention provides a basalt fiber for clothing and an all-round sizing device and method thereof. The sizing device is provided with a sizing roller group that is different from the existing sizing machine, including two sizing rollers arranged opposite and in parallel. The sizing rollers are provided with a three-layer structure of a transmission component, a moving roller and a covering layer; wherein the transmission component is respectively connected to the power component and the adjustment component, the power component drives the moving roller to move axially back and forth through the transmission component, and the adjustment component drives the moving roller to rotate through the transmission component. When the sizing device of the present invention is used, the moving roller is used to clamp and transport the basalt fiber. During the rotation of the moving roller, the slurry in the cavity is brought out to size the basalt fiber. At the same time, the moving roller moves axially back and forth to drive the basalt fiber to rotate and rub the fiber, thereby achieving all-round sizing of the basalt fiber and improving the uniformity of the sizing of the basalt fiber. The sizing device of the present invention utilizes a sizing roller assembly to apply sizing during the basalt fiber conveying process. This allows the basalt fibers to remain dispersed after sizing and avoid adhesion, improving the sizing effect and overcoming the problem of basalt fibers easily accumulating into strands and becoming entangled and knotted during immersion sizing. Furthermore, coloring materials can be added to the slurry to color the basalt fibers, increasing their versatility as fibers for clothing and overcoming the problem of basalt fibers being difficult to color and having a single color in the prior art. Furthermore, the sizing device of the present invention has a simple structure and, in practical applications, can be combined with a factory's basalt fiber manufacturing equipment to achieve continuous preparation and sizing of basalt fibers, reducing costs, providing high economic benefits, and significant industrial application value.
