Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile equipment technology, specifically to a texturing device. Background Technology
[0002] The conventional method for blending PET and PBT involves sequentially cooling, oiling, pre-networking, hot roller treatment, main networking treatment, and winding the composite yarn after parallel spinning to form PET / PBT composite yarn. However, the composite yarn prepared by this method has poor softness and air permeability.
[0003] To improve these properties, PET fibers are first processed into a lightweight web, and then laminated with PBT fibers. This improves the hand feel of the composite yarn, giving it a certain degree of bulkiness, and also improves its air permeability. However, due to limitations in texturing equipment, the nozzles of the texturing machine cannot web-form a single fiber. Therefore, the above method must be carried out in two steps, which is time-consuming and has high production costs. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a texturing device that can control the texturing of a single fiber in a composite yarn.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a texturing device, including a double-hole nozzle, wherein two grooves are provided on the nozzle hole of the double-hole nozzle, and a detachable sealing plate is provided on the side of the nozzle hole away from the groove.
[0006] It also includes a false twister, a cooling plate, a heating box, and a heating roller. The false twister, cooling plate, and heating box are arranged sequentially at the entrance of one of the wire grooves; the heating roller is arranged at the entrance of the other wire groove; and a single-hole nozzle is provided at the outlet of the dual-hole nozzle.
[0007] The nozzle hole diameter is drilled obliquely from top to bottom from the side with the groove to the side away from the groove.
[0008] The diameter of the nozzle orifice gradually increases from the side with the groove to the side away from the groove.
[0009] In particular, on the side where the groove is provided, the nozzle hole has a groove in the circumferential direction.
[0010] The nozzle orifice has a sealing groove on the side away from the wire groove. The sealing groove surrounds the nozzle orifice and has an opening. The sealing groove is adapted to the shape of the sealing sheet. The sealing sheet is inserted into or pulled out of the sealing groove through the opening.
[0011] The inlet of the dual-hole nozzle is provided with a leather roller, a friction roller and a Y-shaped support in sequence, and the inlet of the Y-shaped support is provided with a false twister and a hot roller.
[0012] The top of the Y-shaped support has two triangular ceramic pieces.
[0013] The triangular ceramic piece has a notch at its lower end.
[0014] It also includes a wire shifting plate, which is threadedly connected to the Y-type support.
[0015] The beneficial effects of this utility model are as follows: The texturing equipment of this utility model can adjust the air outlet state of the dual-hole structure through a detachable sealing sheet, so as to add or not add a mesh to any nozzle hole. It can achieve the addition of a mesh to one component of the bicomponent fiber and the non-addition of a mesh to the other component in one step, which can effectively reduce production costs, shorten process time and reduce losses.

[0030] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0031] Please refer to Figure 4 and 5 A texturing device includes a dual-hole nozzle, wherein two grooves are provided on the nozzle orifice of the dual-hole nozzle, and a removable sealing plate is provided on the side of the nozzle orifice away from the grooves.
[0032] As can be seen from the above description, the beneficial effects of this utility model are as follows: This utility model uses a detachable sealing sheet to adjust the air outlet state of the dual-hole structure, realizing the addition or removal of mesh in any nozzle hole. Using the nozzle with the dual-hole structure, PET fiber / POY (pre-oriented yarn) can achieve a light mesh effect through a specific dual-hole nozzle, changing the scheme that requires a two-step composite process (first processing PET fiber into a light mesh, and then composited with PBT fiber) to a one-step process, effectively reducing production costs, shortening process time, and reducing losses.
[0033] Please refer to Figure 1 Furthermore, it also includes a false twister, a cooling plate, a heating box, and a heating roller. The false twister, cooling plate, and heating box are arranged sequentially at the entrance of one trough; the heating roller is arranged at the entrance of the other trough; and a single-hole nozzle is provided at the outlet of the double-hole nozzle.
[0034] As described above, processing PET fibers into a lightweight web and then combining it with heated, semi-stretched PBT fibers creates a fiber composite structure of semi-stretched POY (pre-oriented yarn) + DTY (drawn textured yarn). This results in a composite fiber with a soft, skin-friendly feel while maintaining a certain degree of stiffness, achieving a soft exterior and a firm interior. The PBT fibers undergo point heating and semi-stretching via hot rollers. Compared to the conventional method of using a hot box for line heating and full stretching, this only provides contact heating during stretching, resulting in an incompletely stretched and oriented state. This makes the fiber structure looser, with lower strength compared to fully stretched PBT fibers, a softer feel, and a certain degree of elasticity, producing an effect similar to imitation wool or down, and a more comfortable skin-friendly touch.
[0035] When paired with a single-hole nozzle, fabric diversification and personalization can be achieved while maintaining the fabric's softness, meeting the needs of different consumers and increasing the added value of the product.
[0036] Furthermore, the nozzle orifice diameter is drilled obliquely from top to bottom from the side with the groove to the side away from the groove.
[0037] As can be seen from the above description, the drilling direction of the nozzle hole is consistent with the direction of the silk path, which can reduce resistance, improve efficiency, and increase stability.
[0038] Please refer to Figure 6 Furthermore, the diameter of the nozzle orifice gradually increases from the side with the groove to the side away from the groove.
[0039] As can be seen from the above description, by utilizing the Laval effect, the back aperture of the hole is large and the front aperture is small. When the airflow passes through the narrow area, the speed will increase, which can amplify the impact force of the airflow and achieve energy saving.
[0040] Furthermore, on the side with the groove, the nozzle orifice has a groove in the circumferential direction.
[0041] As can be seen from the above description, the yarns interlock within this groove under the action of airflow.
[0042] Furthermore, a sealing groove is provided on the side of the nozzle orifice away from the wire groove. The sealing groove surrounds the nozzle orifice and has an opening. The sealing groove is adapted to the shape of the sealing sheet, and the sealing sheet is inserted into or pulled out of the sealing groove through the opening.
[0043] As can be seen from the above description, the sealing plate can adjust the air output state by inserting or pulling it out of the sealing groove through the opening, and can add or remove the screen from any nozzle hole.
[0044] Furthermore, the inlet of the dual-hole nozzle is provided with a leather roller, a friction roller and a Y-shaped support in sequence, and a false twister and a hot roller are provided at the inlet of the Y-shaped support.
[0045] As can be seen from the above description, the two strands are kept in an independent state by the skin roller, friction roller and Y-shaped support.
[0046] Please refer to Figure 2 and 3 Furthermore, the top of the Y-shaped support has two triangular ceramic pieces.
[0047] Furthermore, a notch is provided at the lower end of the triangular ceramic piece.
[0048] As described above, under normal circumstances, the yarn exiting the false twister passes through an infeed groove, where the S-direction and Z-direction yarns converge, appearing as one strand instead of two. However, to achieve the lightweight mesh effect after texturing the PET fiber, the yarn of this invention needs to remain in a dual-strand independent state before entering the dual-hole nozzle. Therefore, a Y-shaped support with a "Y" shape is designed. The top of this support has two triangular ceramic pieces. During use, the yarn enters the triangular ceramic pieces through the notch for support, ensuring stable yarn path.
[0049] Furthermore, it also includes a first roller, a second roller, a third roller, a fourth roller, a fifth roller, a sixth roller, a first wire hook, a second wire hook, and a third wire hook; at the entrance of one wire groove, a false twister, a cooling plate, a heating box, and a first roller are arranged in sequence; at the entrance of another wire groove, a second wire hook, a third roller, a heating roller, a first wire hook, and a second roller are arranged in sequence; at the exit of the double-hole nozzle, a third wire hook, a fourth roller, a single-hole nozzle, and a fifth roller are arranged in sequence.
[0050] Furthermore, it also includes a wire shifter plate, which is located below the second roller and is threadedly connected to the Y-type support.
[0051] As can be seen from the above description, the Y-shaped support moves slightly left and right with the wire shifting plate, which can avoid concentrated wear on the roller.
[0052] Please refer to Figures 1-6 The first embodiment of this utility model is as follows: Please refer to... Figures 1-6 The first embodiment of this utility model is: a texturing device, including a false twister 1, a cooling plate 2, a hot box 3, a hot roller 4, a Y-shaped support 5, a friction roller 6, a leather roller 7, a double-hole nozzle 8, a single-hole nozzle 9, a first roller 101, a second roller 102, a third roller 103, a fourth roller 104, a fifth roller 105, a first wire hook 106, a second wire hook 107, and a third wire hook 108.
[0053] The Y-shaped support 5, friction roller 6, leather roller 7, and double-hole nozzle 8 are arranged in sequence. The Y-shaped support 5 includes two triangular ceramic parts 51, with a notch 511 at the bottom of each triangular ceramic part 51. At the entrance of one triangular ceramic part 51, a false twister 1, a cooling plate 2, a hot box 3, and a first roller 101 are arranged in sequence. At the entrance of the other triangular ceramic part 51, a second wire hook 107, a third roller 103, a hot roller 4, a first wire hook 106, and a second roller 102 are arranged in sequence. At the exit of the double-hole nozzle 8, a third wire hook 108, a fourth roller 104, a single-hole nozzle 9, and a fifth roller 105 are arranged in sequence.
[0054] Below the second roller 102 is a wire guide plate, which is threadedly connected to the Y-type support 5. The nozzle hole 81 of the dual-hole nozzle 8 has two corresponding grooves 82. The side of the nozzle hole 81 away from the grooves 82 has a sealing groove and a removable sealing plate 83. The sealing groove surrounds the nozzle hole 81 and has an opening. The sealing groove and the sealing plate 83 are shaped to fit together, and the sealing plate 83 can be inserted into or removed from the sealing groove through the opening. On the side with the grooves 82, the nozzle hole 81 has a circumferential groove 84. The diameter of the nozzle hole 81 increases gradually from top to bottom at a 45° angle from the side with the grooves 82 to the side away from the grooves 82.
[0055] The principle of this invention is as follows: PET fibers pass sequentially through the first roller 101, heating box 3, cooling plate 2, false twister 1, Y-type support 5, friction roller 6, and leather roller 7, and are then pre-networked in the double-hole nozzle 8, and then sequentially through the third wire hook 108 and the fourth roller 104 before entering the single-hole nozzle 9; PBT fibers pass sequentially through the second roller 102, first wire hook 106, heating roller 4, third roller 103, second wire hook 107, Y-type support 5, friction roller 6, and leather roller 7, and are then pre-networked in the double-hole nozzle 8, and then sequentially through the third wire hook 108 and the fourth roller 104 before entering the single-hole nozzle 9; after the PET fibers and PBT fibers are complexed in the single-hole nozzle 9, they enter the fifth roller 105 to obtain a composite bicomponent soft yarn.
[0056] In summary, the texturing equipment provided by this utility model achieves one component being twisted and the other untwisted by sequentially arranging a false twister, a cooling plate, and a hot box at the inlet of one groove of the double-hole nozzle, and a hot roller at the inlet of the other groove. The processed fiber components are sequentially passed through a Y-shaped support, a friction roller, and a leather roller, maintaining two independent states as they enter the double-hole nozzle. A sealing plate is installed in one nozzle hole, so that the twisted component is webped while the untwisted component is not. Then, they are complexed at a single-hole nozzle, forming a semi-drawn POY (pre-oriented yarn) + DTY (drawn textured yarn) fiber composite structure in one step. This results in a composite fiber with a skin-friendly and soft touch, effectively reducing production costs, shortening process time, and reducing waste.
