Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textiles, and particularly relates to a production process of three-layer long-cotton no-twist textile. BACKGROUND

[0002] The existing no-twist pure cotton textile is a fabric directly woven by cotton filaments, and the no-twist yarn is subjected to pressure flattening treatment to form a ribbon-shaped cross-section yarn, so that the traditional twisting process is omitted and the finished product is directly produced. The fabric of this type has a thick and compact appearance, and presents a style similar to silk and wool materials, but the loftiness and skin-friendly touch are slightly poor. The traditional no-twist cotton yarn is slightly inferior to the twisted cotton yarn in terms of yarn strength and wear resistance, but the fabric produced by the twisted cotton yarn has the problem of rigid touch.

[0003] In addition, when the pure cotton fabric is dyed, an overflow dyeing machine needs to be used. However, when the overflow dyeing machine is used, the dye in the machine body is circulated and contacts the cotton fabric for dyeing at the same time, which impacts the cotton fabric, resulting in the separation of flocculent substances, pectin decomposition substances, waxy substances, nitrogen-containing substances, cottonseed shell fragments, pigment particles and foreign fibers and other impurities, which cause the filter plate to be blocked, so that the filter plate needs to be cleaned and replaced in time after long-term use. When the filter plate is cleaned and replaced, the overflow dyeing machine needs to be stopped for operation, which affects the dyeing efficiency.

[0004] In view of the above technical problems, the applicant has developed a production process of three-layer long-cotton no-twist textile, which not only solves the problems of rigid hand feeling and insufficient loftiness and skin-friendly touch of traditional textiles, but also improves the overflow dyeing machine for dyeing process to achieve the purpose of conveniently replacing the filter plate.

[0035] Compared with the prior art, the beneficial effects of the present invention are:

[0036] 1. This invention improves the manufacturing process of three-layer long-staple cotton untwisted textiles by treating the first and third layers of pure cotton yarn with a twisting-then-loosening method. The twisting process arranges the fibers in an orderly manner, while the subsequent loosening alleviates excessive compression between the fibers, resulting in a smoother fabric surface and a softer feel. This "tight-then-loose" process balances strength and comfort, avoiding the roughness that may occur in purely twisted fabrics, and providing a softer, fluffier feel. After loosening, the gaps between the fibers increase, preserving the natural breathability of cotton fibers without affecting moisture absorption. The loosening process also prevents the fibers from becoming overly taut, allowing the fabric to maintain a certain degree of elasticity, reducing stubborn wrinkles when folded or stored, while maintaining dimensional stability and reducing shrinkage after washing. The middle layer, which serves as the skeleton, is treated with high-count cotton yarn, which significantly enhances the tensile strength of the fabric. The breaking strength of double-ply 120-count long-staple cotton yarn can be increased by 30%-50% compared to single-ply yarn. While providing strength support, the fabric's warmth and windproof performance is improved by utilizing the denser and more orderly fiber arrangement on the surface of the ply yarn.

[0037] 2. This invention improves the overflow dyeing machine by setting a replacement mechanism. Rotating the rotating column moves the movable frame into the movable slot. At this time, the bottom of the movable frame blocks the bottom of the movable slot. The top of the movable slot is opened, and a new filter plate is placed into the movable frame. The movable frame then moves downward into the limiting slot. The motor drives the two filter plates to exchange positions. Rotating the rotating column again pushes the movable frame and the old filter plate into the movable slot. The top of the movable slot is opened again to remove the old filter plate. This facilitates filter plate replacement without stopping the machine, avoiding any impact on dyeing efficiency due to filter plate replacement.

[0038] 3. The overflow dyeing machine is equipped with a switching mechanism. The mounting plate is inserted between the two top plates until the fixing block engages in the fixing groove. The mounting base is tightly attached to the top of the filter box, and the top of the movable groove is closed. Rotating the rotating block drives the displacement frame to move. The displacement frame contacts the fixing block and pushes the fixing block to move out of the fixing groove, releasing the fixing of the mounting plate. The mounting plate is then moved out of the movable groove, and the top of the movable groove is opened. This facilitates the opening and closing of the top of the movable groove, and automatically moves the old filter plate out of the movable groove when it is opened. Attached Figure Description

[0077] In this embodiment: the dye passes through the liquid tank 803 and the filter box 15. When replacing the filter plate 16, the rotating column 811 is rotated. The rotation of the rotating column 811 drives the first bevel gear 812 to rotate, which in turn drives the second bevel gear 813 to rotate. The rotation of the second bevel gear 813 drives the first threaded rod 814 to rotate, which in turn drives the connecting rod 815 to move. The connecting rod 815 slides upward along the vertical groove 818 and inserts into the connecting groove 809, pushing the movable frame 805 upward. At this time, the C-shaped frame 816 is displaced by the elastic force of the second spring 817. The top of the 6th component moves into the slot 810, fixing the movable frame 805 and the connecting rod 815. The movable frame 805 continues to move upward into the movable groove 819. When the top of the movable frame 805 contacts the bottom of the top plate 821, the top of the pressing block 808 contacts the bottom of the top plate 821. The pressing block 808 is displaced under force, and the displacement of the pressing block 808 pushes the locking block 806 to move, compressing the first spring 807.

At this time, the bottom of the movable frame 805 blocks the bottom of the movable groove 819, and the sealing ring 820 improves the sealing between the movable frame 805 and the movable groove 819.

[0078] After completion, the top of the movable slot 819 is opened by the cooperation of the parts inside the switching mechanism 9, and the new filter plate 16 is placed into the movable frame 805. Then, the top of the movable slot 819 is closed, and the filter plate 16 is connected to the inner wall of the movable frame 805. Rotating the rotating column 811 causes the connecting rod 815 to move downward. The displacement of the connecting rod 815 causes the movable frame 805 to move downward. At this time, the pressing block 808 separates from the top plate 821, and the locking block 806 is reset by the elastic force of the first spring 807. The locking block 806 contacts the top of the filter plate 16, fixing the filter plate 16 to the movable frame 805. 05; until the movable frame 805 is fully inserted into the limiting groove 804, at which point the bottom of the C-shaped frame 816 enters the vertical groove 818, and the C-shaped frame 816 is displaced by force into the connecting rod 815 (the upper and lower sides of the extended end of the C-shaped frame 816 are provided with inclined surfaces), the C-shaped frame 816 is displaced out of the slot 810, and the fixation between the movable frame 805 and the connecting rod 815 is removed, until the connecting rod 815 is displaced out of the connecting groove 809 and enters the vertical groove 818; after completion, the motor 801 is started, the motor 801 drives the rotating disk 802 to rotate, and the rotating disk 802 drives the two filter plates 16 to exchange positions.

[0079] After completion, rotate the rotating column 811 again. The connecting rod 815 pushes another movable frame 805 and the old filter plate 16 into the movable slot 819. Open the top of the movable slot 819 again, remove the old filter plate 16, close the top of the movable slot 819, and reset the movable frame 805. This design facilitates the replacement of the filter plate 16 without stopping the machine, avoiding any impact on dyeing efficiency due to filter plate 16 replacement.

[0080] Please refer to this carefully. Figures 7 to 10 The switching mechanism 9 includes a fixing groove 901, which is formed on the outer wall of the top plate 821. A mounting plate 902 is slidably connected between the two top plates 821. A mounting base 903 is fixedly connected to the top of the mounting plate 902. Fixing blocks 904 extending from the mounting plate 902 are symmetrically slidably connected inside the mounting plate 902. A third spring 905 connects the fixing blocks 904 and the mounting plate 902. An inverted "mountain" shaped displacement bracket 90 is slidably connected inside the mounting plate 902 and the mounting base 903. 6. An L-shaped plate 909 is fixedly connected to the top of the filter plate 16. A rotating block 908 is rotatably connected to the top of the mounting base 903. A second threaded rod 907 is fixedly connected to the bottom of the rotating block 908. The second threaded rod 907 extends into the interior of the displacement frame 906. The bottom of the displacement frame 906 extends to the bottom of the mounting plate 902. A slider 910 is slidably connected inside the displacement frame 906. The slider 910 extends out of the displacement frame 906. A fourth spring 911 is connected between the slider 910 and the displacement frame 906.

[0081] In this embodiment: when closing the top of the movable slot 819, the mounting plate 902 is inserted between the two top plates 821 until the fixing block 904 is engaged into the fixing slot 901 by the elastic force of the third spring 905, and the mounting base 903 is tightly attached to the top of the filter box 15, thus closing the top of the movable slot 819; when opening the top of the movable slot 819, the rotating block 908 is rotated, which drives the second threaded rod 907 to rotate, and the second threaded rod 907 to rotate, which drives the displacement frame 906 to move. The displacement frame 906 moves and contacts the fixing block 904, pushing the fixing block 904 to move. The fixing block 904 moves out of the fixing slot 901, the fixing of the mounting plate 902 is released, and the mounting plate 902 is moved out of the movable slot 819, thus opening the top of the movable slot 819.

[0082] When the old filter plate 16 needs to be removed, opening the top of the movable slot 819 causes the rotating block 908 to rotate, moving the displacement frame 906 downwards. This displacement of the displacement frame 906 causes the slider 910 to move, contacting the L-shaped plate 909. The slider 910, under pressure, moves into the displacement frame 906, compressing the fourth spring 911 until it separates from the top of the L-shaped plate 909. The slider 910 then returns to its original position under the elastic force of the fourth spring 911, contacting the top and bottom of the L-shaped plate 909. Thus, when the mounting plate 902 is moved out of the movable slot 819, the displacement frame 906, through the slider 910, pulls the L-shaped plate 909 and the filter plate 16 out of the movable slot 819. This design facilitates opening and closing the top of the movable slot 819 and automatically moves the old filter plate 16 out of the movable slot 819 when it is opened.

[0086] In this embodiment: rotating the rotating column 811 causes the first bevel gear 812 to rotate, the first bevel gear 812 causes the second bevel gear 813 to rotate, the second bevel gear 813 causes the first threaded rod 814 to rotate, the first threaded rod 814 causes the connecting rod 815 to move, and the connecting rod 815 slides upward along the vertical groove 818.

[0087] Please refer to this carefully. Figures 3 to 8 The top outer wall of the connecting rod 815 fits against the inner wall of the connecting groove 809, and the inner wall of the slot 810 fits against the top outer wall of the C-shaped frame 816.

[0088] In this embodiment: the connecting rod 815 is inserted into the connecting groove 809 and pushes the movable frame 805 upward. At this time, the C-shaped frame 816 is displaced by the elastic force of the second spring 817. The top of the C-shaped frame 816 is displaced into the slot 810, and the movable frame 805 and the connecting rod 815 are fixed. The movable frame 805 continues to move upward and enters the movable groove 819.

[0090] In this embodiment: the movable frame 805 continues to move upward into the movable groove 819. When the top end of the movable frame 805 contacts the bottom end of the top plate 821, the top end of the pressing block 808 contacts the bottom end of the top plate 821. The pressing block 808 is displaced by force. The displacement of the pressing block 808 pushes the locking block 806 to move, causing compression on the first spring 807. The locking block 806 moves into the interior of the movable frame 805.

The slider 910 extends out of one end of the displacement frame 906 and is provided with a third inclined surface.

[0094] In this embodiment: Rotating the rotating block 908 causes the second threaded rod 907 to rotate, which in turn causes the displacement frame 906 to move. The displacement frame 906 then contacts the fixed block 904, pushing the fixed block 904 to move out of the fixed groove 901, thus releasing the fixing of the mounting plate 902 and moving the mounting plate 902 out of the movable groove 819. The top of the movable groove 819 is then opened. When the old filter plate 16 is removed and the top of the movable groove 819 is opened, rotating the rotating block 908 causes the displacement frame 906 to move. 6. The displacement frame 906 moves downward, causing the slider 910 to move as well. The slider 910 moves and comes into contact with the L-shaped plate 909. The slider 910 is displaced by force and enters the displacement frame 906, which compresses the fourth spring 911 until the slider 910 separates from the top of the L-shaped plate 909. The slider 910 is reset by the elastic force of the fourth spring 911 and comes into contact with the top and bottom of the L-shaped plate 909. Thus, when the mounting plate 902 is moved out of the movable groove 819, the displacement frame 906 pulls the L-shaped plate 909 and the filter plate 16 out of the movable groove 819 through the slider 910.
