Description

Technical Field

[0001] The invention relates to the field of yarn dyeing, in particular to a sample yarn auxiliary dyeing device and a dyeing method. Background Art

[0002] In the textile process, it is often necessary to demonstrate the dyeing effect through the corresponding sample yarn before the order is received or the bulk goods are delivered. Usually, the traditional method is to roll the yarn into a cheese yarn, and then use the cheese yarn as the sample yarn to demonstrate the dyeing effect.

[0003] However, the formation of cheese yarn requires more complex equipment and processes, such as the use of winding equipment and corresponding winding processes. This will slow down the generation rate of sample yarn. Especially when multiple sample yarns are needed for comparison, the traditional method will take a long time to prepare the sample yarn, resulting in a longer delivery cycle for the sample yarn, which will in turn extend the time cycle for projects such as order introduction or bulk delivery, which is not conducive to efficient production. In addition, the yarn will have tension changes during the dyeing process, and the traditional method is prone to yarn deformation, which will lead to a decrease in the quality of the sample yarn. Summary of the invention

[0004] Based on this, it is necessary to provide a sample yarn auxiliary dyeing device and a dyeing method. The sample yarn auxiliary dyeing device can be used to quickly prepare the sample yarn and reduce the risk of deformation of the sample yarn during the dyeing process.

[0005] In order to solve the above technical problems, the technical solution of the present invention is:

[0006] A sample yarn auxiliary dyeing device comprises a yarn winding member, a first elastic member, a second elastic member, a first yarn hooking member and a second yarn hooking member;

[0007] The yarn winding member is used for winding the sample yarn, the yarn winding member is a hollow structure, and a dye liquid channel for dye liquid to pass through the side wall of the yarn winding member;

[0008] The first elastic member and the second elastic member are rotatably connected to two ends of the yarn winding member respectively;

[0009] The first yarn hooking member is fixed to one end of the first elastic member away from the yarn winding member, and the second yarn hooking member is fixed to one end of the second elastic member away from the yarn winding member. The first yarn hooking member and the second yarn hooking member can cooperate with each other to hook the two ends of the sample yarn.

[0010] In one embodiment, a side wall of the yarn winding member is provided with a plurality of through holes to form a plurality of dye liquid channels.

[0011] In one embodiment, the through hole has a diameter of 0.3 cm to 0.5 cm.

[0012] In one embodiment, the yarn winding member is cylindrical, and the inner diameter of the yarn winding member is 3 cm to 6 cm.

[0013] In one embodiment, the wall thickness of the yarn winding member is 1 cm to 1.5 cm.

[0014] In one embodiment, the axial length of the yarn winding member is 10 cm to 15 cm.

[0015] In one embodiment, the auxiliary dyeing device also includes a first mounting ring; the first mounting ring is fixed to an end of the first elastic member away from the first yarn hooking member, and the first mounting ring is passed through the side wall of the yarn winding member for mounting the first elastic member.

[0016] In one embodiment, the auxiliary dyeing device also includes a second mounting ring; the second mounting ring is fixed to an end of the second elastic member away from the second yarn hooking member, and the second mounting ring is passed through the side wall of the yarn winding member for installing the second elastic member.

[0017] A sample yarn dyeing method, using the auxiliary dyeing device described in any of the above embodiments, the dyeing method comprises the following steps:

[0018] Hooking one end of the sample yarn on the first yarn hooking member, then winding the sample yarn on the yarn winding member, and then hooking the other end of the sample yarn on the second yarn hooking member to obtain a piece to be dyed;

[0019] The workpiece to be dyed is immersed in the dyeing solution.

[0020] In one embodiment, the number of winding layers of the sample yarn on the yarn winding member is 1 to 5.

[0021] The sample yarn auxiliary dyeing device of the present invention comprises a yarn winding member, a first elastic member, a second elastic member, a first yarn hooking member and a second yarn hooking member. The yarn winding member is used to wind the sample yarn, the yarn winding member is a hollow structure, and the side wall of the yarn winding member is penetrated by a dye liquid channel for dye liquid to pass through. The first elastic member and the second elastic member are rotatably connected to the two ends of the yarn winding member respectively. The first yarn hooking member is fixed to one end of the first elastic member away from the yarn winding member, and the second yarn hooking member is fixed to one end of the second elastic member away from the yarn winding member. The first yarn hooking member and the second yarn hooking member can cooperate with each other to hook the two ends of the sample yarn. In the present invention, the inventor has conducted in-depth research on the dyeing process and dyeing effect of the sample yarn, and cleverly designed a sample yarn auxiliary dyeing device.

Then the piece to be dyed is immersed in the dye solution for dyeing. During the dyeing process, the dye solution interacts inside and outside through the dye solution channel on the yarn winding member to improve the dyeing uniformity of the sample yarn. In addition, since the first elastic member and the second elastic member are rotatably connected to the two ends of the yarn winding member, under the action of the first elastic member and the second elastic member, multi-directional tension can be applied to the sample yarn during the dyeing process, which can effectively reduce the risk of deformation of the sample yarn during the dyeing process and maintain the quality of the sample yarn. At the same time, since the environment of the sample yarn has changed significantly after the sample yarn is dyed, the yarn may also undergo a significant deformation. The auxiliary dyeing device of the present invention can also reduce the risk of deformation of the yarn after dyeing and improve the quality of the sample yarn.

[0022] Furthermore, by using the auxiliary dyeing device of the present invention, the staff only needs to hook one end of the sample yarn on the first yarn hooking member, then wind the sample yarn on the yarn winding member, and then hook the other end of the sample yarn on the second yarn hooking member to obtain the corresponding piece to be dyed, without the need to use complex winding equipment and winding process. This is simple and easy to operate, can effectively improve the preparation efficiency of sample yarn, shorten the time cycle of projects such as order introduction or bulk delivery, and improve production efficiency; it is conducive to quickly providing customers with corresponding sample yarns, buying time for the introduction of new customers, and improving the competitiveness of enterprises.

[0031] See also Figure 1An embodiment of the present invention provides a sample yarn auxiliary dyeing device 100, which includes a yarn winding member 101, a first elastic member 102, a second elastic member 105, a first yarn hooking member 103 and a second yarn hooking member 106. The yarn winding member 101 is used to wind the sample yarn. The yarn winding member 101 is a hollow structure, and a dye liquid channel 1011 for dye liquid to pass through the side wall of the yarn winding member 101 is penetrated. The first elastic member 102 and the second elastic member 105 are rotatably connected to the two ends of the yarn winding member 101. The first yarn hooking member 103 is fixed to one end of the first elastic member 102 away from the yarn winding member 101, and the second yarn hooking member 106 is fixed to one end of the second elastic member 105 away from the yarn winding member 101. The first yarn hooking member 103 and the second yarn hooking member 106 can cooperate with each other to hook the two ends of the sample yarn.

[0032] The auxiliary dyeing device in this embodiment is based on a yarn winding member 101 with a hollow structure and a dye liquid channel 1011 on the side wall. The first elastic member 102 and the second elastic member 105 are respectively arranged at both ends of the yarn winding member 101, and the first and second elastic members 102 and 105 are respectively provided with a first yarn hooking member 103 and a second yarn hooking member 106 at one end. When using the auxiliary dyeing device, one end of the sample yarn is hooked on the first yarn hooking member 103, and then the sample yarn is wound on the yarn winding member 101, and then the other end of the sample yarn is hooked on the second yarn hooking member 106 to obtain a piece to be dyed. Then the piece to be dyed is immersed in the dye liquid for dyeing. During the dyeing process, the dye liquid interacts inside and outside through the dye liquid channel 1011 on the yarn winding member 101 to improve the dyeing uniformity of the sample yarn. In addition, since the first elastic member 102 and the second elastic member 105 are rotatably connected to the two ends of the yarn winding member 101, under the action of the first elastic member 102 and the second elastic member 105, multi-directional tension can be applied to the sample yarn during the dyeing process, which can effectively reduce the risk of deformation of the sample yarn during the dyeing process and maintain the quality of the sample yarn. At the same time, since the environment in which the sample yarn is located has undergone a significant change after the sample yarn is dyed, the yarn may also undergo a significant deformation. The use of the auxiliary dyeing device in this embodiment can also reduce the risk of deformation of the yarn after dyeing and improve the quality of the sample yarn. Furthermore, using the auxiliary dyeing device in this embodiment, the staff only needs to hook one end of the sample yarn on the first yarn hooking member 103, then wind the sample yarn on the yarn winding member 101, and then hook the other end of the sample yarn on the second yarn hooking member 106, and the corresponding piece to be dyed can be obtained without the need to use complex winding equipment and winding process. This operation is simple and easy, and can effectively improve the preparation efficiency of sample yarns, shorten the time cycle of projects such as order introduction or bulk delivery, and improve production efficiency. It is conducive to quickly providing customers with corresponding sample yarns, buying time for the introduction of new customers, and improving the competitiveness of the company.

[0033] Preferably, the first elastic member 102 and the second elastic member 105 are hinged to two ends of the yarn winding member 101 respectively.

[0034] Preferably, during the dyeing process, multiple strands of sample yarn are wound in parallel, so that the same end of the multiple strands of sample yarn is hooked on the first yarn hooking member 103, and the other end is hooked on the second yarn hooking member 106. This can improve the stability of the force exerted by the first yarn hooking member 103 and the second yarn hooking member 106 on the sample yarn, and can also improve the winding efficiency, thereby further improving the preparation efficiency of the sample yarn.

[0035] In a specific example, the auxiliary dyeing device is composed of a yarn winding member 101, a first elastic member 102, a second elastic member 105, a first yarn hooking member 103 and a second yarn hooking member 106. The yarn winding member 101 is used to wind the sample yarn. The yarn winding member 101 is a hollow structure, and the side wall of the yarn winding member 101 is penetrated by a dye liquid channel 1011 for dye liquid to pass through. The first elastic member 102 and the second elastic member 105 are rotatably connected to the two ends of the yarn winding member 101. The first yarn hooking member 103 is fixed to one end of the first elastic member 102 away from the yarn winding member 101, and the second yarn hooking member 106 is fixed to one end of the second elastic member 105 away from the yarn winding member 101. The first yarn hooking member 103 and the second yarn hooking member 106 can cooperate with each other to hook the two ends of the sample yarn. In this example, the auxiliary dyeing device can be formed only by the yarn winding member 101, the first elastic member 102, the second elastic member 105, the first yarn hooking member 103 and the second yarn hooking member 106, which can also realize the auxiliary dyeing of the sample yarn and effectively improve the preparation efficiency of the sample yarn.

[0036] Preferably, in a specific example, the auxiliary dyeing device is used for auxiliary dyeing of synthetic fiber sample yarn. That is, this example provides an auxiliary dyeing device for synthetic fiber sample yarn, which includes a yarn winding member 101, a first elastic member 102, a second elastic member 105, a first yarn hooking member 103 and a second yarn hooking member 106. The yarn winding member 101 is used to wind the sample yarn, and the yarn winding member 101 is a hollow structure, and the side wall of the yarn winding member 101 is penetrated by a dye liquid channel 1011 for dye liquid to pass through. The first elastic member 102 and the second elastic member 105 are rotatably connected to the two ends of the yarn winding member 101 respectively. The first yarn hooking member 103 is fixed to one end of the first elastic member 102 away from the yarn winding member 101, and the second yarn hooking member 106 is fixed to one end of the second elastic member 105 away from the yarn winding member 101. The first yarn hooking member 103 and the second yarn hooking member 106 can cooperate with each other to hook the two ends of the sample yarn. The synthetic fiber can be, but is not limited to, polyester fiber, nylon fiber, etc. During the dyeing process, due to the high temperature of the dye solution, such as the temperature of the dye solution being 120°C to 140°C, the synthetic fiber is more likely to be deformed. Using the auxiliary dyeing device in this example, the two ends of the synthetic fiber sample yarn are hooked on the first yarn hooking member 103 and the second yarn hooking member 106 respectively, and through the action of the first elastic member 102 and the second elastic member 105, a multi-directional pulling force can be applied to the synthetic fiber sample yarn, effectively reducing the risk of deformation of the synthetic fiber sample yarn during the dyeing process and maintaining the quality of the synthetic fiber sample yarn.

[0037] It can be understood that, in another specific example, the synthetic fiber sample yarn auxiliary dyeing device is composed of a yarn winding member 101, a first elastic member 102, a second elastic member 105, a first yarn hooking member 103 and a second yarn hooking member 106. The yarn winding member 101 is used to wind the sample yarn. The yarn winding member 101 is a hollow structure, and the side wall of the yarn winding member 101 is penetrated by a dye liquid channel 1011 for dye liquid to pass through. The first elastic member 102 and the second elastic member 105 are rotatably connected to the two ends of the yarn winding member 101. The first yarn hooking member 103 is fixed to one end of the first elastic member 102 away from the yarn winding member 101, and the second yarn hooking member 106 is fixed to one end of the second elastic member 105 away from the yarn winding member 101. The first yarn hooking member 103 and the second yarn hooking member 106 can cooperate with each other to hook the two ends of the sample yarn. In this example, the synthetic fiber sample yarn auxiliary dyeing device can be formed only by the yarn winding member 101, the first elastic member 102, the second elastic member 105, the first yarn hooking member 103 and the second yarn hooking member 106, and the auxiliary dyeing effect of the sample yarn can also be achieved.

[0038] In a specific example, the first elastic member 102 and the first yarn hooking member 103 are integrally formed. At this time, the force between the first elastic member 102 and the first yarn hooking member 103 can be transmitted more stably, which can improve the stability of yarn winding.

[0039] Further, the second elastic member 105 and the second yarn hooking member 106 are an integrally formed structure. At this time, the force between the second elastic member 105 and the second yarn hooking member 106 can be transmitted more stably, which can improve the stability of yarn winding.

[0040] Furthermore, the yarn winding member 101 is a stainless steel yarn winding member; and / or, the first elastic member 102 is a first stainless steel elastic member; and / or, the second elastic member 105 is a second stainless steel elastic member; and / or, the first yarn hooking member 103 is a first stainless steel yarn hooking member; and / or, the second yarn hooking member 106 is a second stainless steel yarn hooking member. The stainless steel yarn winding member, the first stainless steel elastic member, the second stainless steel elastic member, the first stainless steel yarn hooking member and the second stainless steel yarn hooking member have stable performance, are not prone to staining, rusting and other problems during the dyeing process, and can further improve the dyeing effect of the sample yarn.

[0041] As a preferred solution, the side wall of the yarn winding member 101 is provided with a plurality of through holes to form a plurality of dye liquid channels 1011. By providing a plurality of through holes, the uniformity of dye liquid interaction can be improved, and the dyeing effect of the sample yarn can be improved. Further, the plurality of through holes are evenly distributed on the side wall of the yarn winding member 101, which can further improve the uniformity of dye liquid interaction and improve the dyeing effect of the sample yarn. For further information, please refer to Figure 1 In this embodiment, the dye channel 1011 is a plurality of circular through holes evenly distributed on the side wall of the yarn winding member 101. Specifically, the aperture of the through hole is 0.3 cm to 0.5 cm. Preferably, the aperture of the through hole is 0.3 cm to 0.45 cm; more preferably, the aperture of the through hole is 0.3 cm to 0.35 cm; further preferably, the aperture of the through hole is 0.3 cm to 0.32 cm.

[0042] It is understood that as a preferred shape of the yarn winding member 101, the yarn winding member 101 is cylindrical, and the inner diameter of the yarn winding member 101 is 3cm to 6cm. When the yarn winding member 101 is cylindrical, the sample yarn can be more evenly wound on the yarn winding member 101, which can improve the consistency of the sample yarn dyeing. For example, the inner diameter of the yarn winding member 101 can be but not limited to 3cm, 3.5cm, 4cm, 4.5cm, 5cm, 5.5cm or 6cm, etc. Within the inner diameter range of 3cm to 6cm, the dye liquid can smoothly interact in the inner space and the outer space of the yarn winding member 101, maintaining a good and stable dyeing effect. Further, the wall thickness of the yarn winding member 101 is 1cm to 1.5cm. It is understood that the wall thickness of the yarn winding member 101 can be but not limited to 1cm, 1.1cm, 1.2cm, 1.3cm, 1.4cm and 1.5cm. Preferably, the wall thickness of the yarn winding member 101 is 1 cm to 1.2 cm.

[0043] In a specific example, the axial length of the yarn winding member 101 is 10 cm to 15 cm. Within this range, the axial length of the yarn winding member 101 can wind a suitable number of sample yarns and keep the two ends of the sample yarn after winding at a suitable distance from the two ends of the yarn winding member 101, so that the first elastic member 102 and the second elastic member 105 can fully play the role, so that during the dyeing process, the first elastic member 102 and the second elastic member 105 can fully balance the deformation of the sample yarn, effectively maintain the shape of the sample yarn during and after dyeing, reduce the risk of shrinkage of the sample yarn, and improve the quality of the sample yarn. It is understandable that the axial length of the yarn winding member 101 can be but is not limited to 10 cm, 11 cm, 12 cm, 13 cm, 14 cm or 15 cm, etc.

[0044] In a specific example, the yarn winding member 101 is cylindrical, with an inner diameter of 3cm to 6cm, a wall thickness of 1cm to 1.5cm, and an axial length of 10cm to 15cm. At this time, the size of the yarn winding member 101 is small, which is particularly convenient during use, and can fully demonstrate the convenience that traditional cheese yarn sampling does not have. And using the yarn winding member 101 within this size range, the sample yarn can be wound in an appropriate quantity to meet the needs of sample display, and the dyeing effect can well reflect the quality of bulk production. At the same time, it can also effectively improve the preparation efficiency of sample yarns, shorten the time cycle of projects such as order introduction or bulk delivery, and improve production efficiency; it is conducive to quickly providing customers with corresponding sample yarns, buying time for the introduction of new customers, and improving the competitiveness of enterprises.

[0045] Please refer again Figure 1, the auxiliary dyeing device also includes a first mounting ring 104; the first mounting ring 104 is fixed to one end of the first elastic member 102 away from the first yarn hooking member 103, and the first mounting ring 104 is penetrated through the side wall of the yarn winding member 101 for installing the first elastic member 102. It can be understood that the first mounting ring 104 is penetrated through the side wall of the yarn winding member 101, which is manifested as the first mounting ring 104 passing through the dye liquid channel 1011 and the hollow structure of the yarn winding member 101 in sequence, and then forming a ring. In this way, the first mounting ring 104 can move in multiple directions on the yarn winding member 101. By having the first mounting ring 104 penetrate through the side wall of the yarn winding member 101, the first elastic member 102 can be installed on the yarn winding member 101, and the movement direction of the first mounting ring 104 on the yarn winding member 101 has good diversity. When the sample yarn is hooked on the first yarn hooking member 103, the first installation ring 104 can move in multiple directions to provide multiple pulling forces for the sample yarn and maintain the stability of the shape of the sample yarn. Preferably, the first installation ring 104, the first elastic member 102 and the first yarn hooking member 103 are an integrally formed structure. At this time, the force between the first installation ring 104, the first elastic member 102 and the first yarn hooking member 103 can be stably transmitted, thereby improving the stability of the force of the auxiliary dyeing device on the sample yarn.

[0046] Furthermore, the auxiliary dyeing device also includes a second mounting ring 107; the second mounting ring 107 is fixed to one end of the second elastic member 105 away from the second yarn hooking member 106, and the second mounting ring 107 is penetrated through the side wall of the yarn winding member 101 for installing the second elastic member 105. It can be understood that the second mounting ring 107 is penetrated through the side wall of the yarn winding member 101, which is manifested as the second mounting ring 107 passing through the dye liquid channel 1011 and the hollow structure of the yarn winding member 101 in sequence, and then forming a ring. In this way, the second mounting ring 107 can move in multiple directions on the yarn winding member 101. By penetrating the second mounting ring 107 through the side wall of the yarn winding member 101, the second elastic member 105 can be installed on the yarn winding member 101, and the movement direction of the second mounting ring 107 on the yarn winding member 101 has good diversity. When the sample yarn is hooked on the second yarn hooking member 106, the second mounting ring 107 can move in multiple directions, provide multiple pulling forces for the sample yarn, and maintain the stability of the shape of the sample yarn. Preferably, the second mounting ring 107, the second elastic member 105, and the second yarn hooking member 106 are an integrally formed structure. At this time, the force between the second mounting ring 107, the second elastic member 105, and the second yarn hooking member 106 can be stably transmitted, thereby improving the stability of the force of the auxiliary dyeing device on the sample yarn.

[0047] Another embodiment of the present invention provides a sample yarn dyeing method, which adopts the above-mentioned auxiliary dyeing device, and the dyeing method includes the following steps: hooking one end of the sample yarn on the first yarn hooking member 103, then winding the sample yarn on the yarn winding member 101, and then hooking the other end of the sample yarn on the second yarn hooking member 106 to obtain the piece to be dyed; immersing the piece to be dyed in the dye solution. The dyeing method in this embodiment is simple and easy to operate, and the dyeing effect can well reflect the quality of the bulk production. The dyeing method in this embodiment can replace the traditional cheese yarn sample making, provide a convenient and efficient sample yarn dyeing sample making method, improve the preparation efficiency of the sample yarn, shorten the time cycle of projects such as order introduction or bulk delivery, and improve production efficiency; it is conducive to quickly providing customers with corresponding sample yarns, buying time for the introduction of new customers, and improving the competitiveness of enterprises.

[0048] Preferably, in order to obtain a better dyeing effect, the number of winding layers of the sample yarn on the yarn winding member 101 is 1 to 5 layers. For example, the number of winding layers of the sample yarn on the yarn winding member 101 is 1, 2, 3, 4 or 5 layers. If the number of winding layers of the sample yarn on the yarn winding member 101 is too many, the dyeing effect of the inner and outer layers of the yarn is difficult to control, and more dyeing time is required to obtain a consistent dyeing effect for the yarn. Further preferably, the number of winding layers of the sample yarn on the yarn winding member 101 is 4 layers. At this time, the sample yarn can be evenly wound on the yarn winding member 101, is not easy to fall off, and the dyeing effect between each layer is more uniform.

[0049] It should be noted that when the yarn is wound onto the yarn winding member 101, keeping the yarn evenly and neatly wound can further improve the winding effect and dyeing effect. At the same time, when the yarn is wound, after one end of the yarn is hooked on the first yarn hooking member 103, the first elastic member 102 is kept in a state with a certain tension, so that a certain tension can be applied to the yarn, which is conducive to the shaping of the yarn. Similarly, after the other end of the yarn is hooked on the second yarn hooking member 106, the first elastic member 102 is kept in a state with a certain tension, so that a tension can be further applied to the yarn to maintain the shape of the yarn. That is, after the yarn winding is completed, the two ends of the yarn are hooked on the first yarn hooking member 103 and the second yarn hooking member 106 respectively. At this time, the first elastic member 102 and the second elastic member 105 are both in a state with a certain tension, which can keep the shape of the yarn stable during the dyeing process and improve the dyeing quality of the yarn.

[0050] Furthermore, if the workpiece to be dyed needs to be placed in a container before dyeing, the container should be cleaned before the workpiece to be dyed is immersed in the dye solution to ensure that the container is in a clean state, so as to avoid the problem of staining during the dyeing process. For example, if the container is a steel cup, the steel cup and the lid should be cleaned before the workpiece to be dyed is immersed in the dye solution to ensure that the steel cup and the lid are in a clean state.

[0051] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
