Description

Technical Field

[0001] The utility model belongs to the technical field of sewing threads, and in particular relates to a tensile sewing thread and a thread barrel. Background Art

[0002] Sewing thread is the thread needed for knitted clothing products. Sewing thread can be divided into three categories according to the raw materials: natural fiber, synthetic fiber sewing thread and mixed sewing thread. With the development of the polyester industry, more and more pure polyester fiber is used as the raw material of sewing thread. Polyester fiber is a high-quality synthetic fiber, and the sewing thread made from it has high strength.

[0003] However, the tensile strength of existing sewing threads is not enough, and the existing sewing threads are usually wound on the surface of the bobbin for temporary storage. The existing winding method mostly uses the sewing thread to be repeatedly wound along the surface of the bobbin in circles. This operation method easily causes the thread ends of the sewing thread to fall off the bobbin in the early stage of winding. The operator needs to manually fix the thread ends when winding the sewing thread in the early stage, and the winding efficiency is relatively slow.

[0004] In order to solve the above problems, the present application proposes a tensile sewing thread and a thread barrel. Utility Model Content

[0005] In view of the problems in the related art, the utility model provides a tensile sewing thread and a thread barrel to overcome the above technical problems existing in the existing related art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A tensile sewing thread comprises a main thread, a plurality of sub-threads are fixedly connected to the outer surface of the main thread, a filling layer is arranged on the outer surface of the sub-threads, a plurality of tensile threads are wound around the outer surface of the filling layer, and a fireproof layer is arranged on the outer surface of the tensile thread.

[0008] Preferably, the material of the filling layer is bamboo charcoal fiber. By setting the filling layer, because the material of the filling layer is bamboo charcoal fiber, the filling layer has the characteristics of moisture absorption, antibacterial, antibacterial, winter warmth and environmental protection.

[0009] Preferably, the material of the fireproof layer is basalt fiber. By setting the fireproof layer, because the material of the fireproof layer is fireproof steel fiber, the fireproof layer has the characteristics of high strength and permanent flame retardancy, and can properly reduce the influence of external temperature.

[0010] A bobbin of tensile sewing thread comprises a winding rod, a positioning block is fixedly connected to the outer surface of the winding rod, a positioning hole is provided on the outer surface of the positioning block, a winding groove is provided on the outer surface of the positioning block, the tensile sewing thread is wound on the positioning block, and a limiting circular block is detachably installed on the outer surface of the winding rod.

[0011] Preferably, the side of the limiting circle away from the winding rod is fixedly connected to a support block. By setting the support block, when the winding rod is placed vertically, the support block can provide supporting force for the limiting circle and the winding rod as a whole, so as to facilitate the winding rod and the limiting circle to stand vertically stably as a whole.

[0012] Preferably, a round handle is fixedly connected to the side of the limiting circular block away from the winding rod, the height of the round handle is less than the height of the supporting block, and a plurality of anti-slip particles are provided on the outer surface of the round handle. By providing the round handle and the anti-slip particles, the operator can drive the limiting circular block to rotate as a whole by holding the round handle, and the anti-slip particles on the surface of the round handle can increase the friction between the round handle and the operator, which is beneficial for the operator to stably control the rotation of the limiting circular block.

[0013] Preferably, a threaded hole is provided on the outer surface of the winding rod, and a threaded rod is welded to the side of the limiting circle close to the winding rod. The threaded rod is threadedly connected to the inner cavity of the winding rod. By setting the threaded hole and the threaded rod, the operator can drive the limiting circle to move away from the winding rod by rotating the threaded rod counterclockwise, which is convenient for the operator to quickly disassemble and replace the limiting circle.

[0014] To sum up, the technical effects and advantages of the utility model are as follows: the tensile-resistant sewing thread and the bobbin, through the coordinated use of the main line, the sub-line, the filling layer, the tensile-resistant line and the fireproof layer, achieve the effect of improving the tensile-resistant performance of the sewing thread; through the coordinated use of the winding rod positioning block, the positioning hole, the winding groove and the limiting circle block, the sewing thread is stably wound on the surface of the winding rod, and the sewing thread is prevented from accidentally falling off the surface of the winding rod as much as possible; through the coordinated use of the limiting circle block, the round handle and the anti-slip particles, the operator can stably and labor-savingly turn the limiting circle block.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-2 A tensile sewing thread comprises a main thread 1, and a plurality of sub-threads 2 are fixedly connected to the outer surface of the main thread 1. The materials of the main thread 1 and the sub-threads 2 are both acrylic cotton fiber. Cotton fiber is a chemical fiber fabric, and its scientific name is polyacrylonitrile fiber. The performance of polyacrylonitrile fiber is very similar to wool and has good elasticity. A filling layer 3 is arranged on the outer surface of the sub-thread 2. The material of the filling layer 3 is bamboo charcoal fiber. The bamboo charcoal fiber has the characteristics of moisture absorption and breathability, antibacterial and antibacterial, warm in winter and cool in summer, and green and environmental protection. A plurality of tensile threads 4 are wound around the outer surface of the filling layer 3. The material of the tensile threads 4 is nylon fiber, that is, polyamide fiber. The most prominent advantage of the tensile threads is that the wear resistance is higher than that of all other fibers. The use of the tensile threads 4 can increase the overall strength of the sewing thread.

[0024] Reference Figure 1-2 The outer surface of the tensile wire 4 is provided with a fireproof layer 5, and the material of the fireproof layer 5 is basalt fiber. Basalt fiber: continuous fiber drawn from natural basalt. Basalt continuous fiber not only has high strength, but also has many excellent properties such as electrical insulation, corrosion resistance, and high temperature resistance. The fireproof layer 5 uses basalt fiber to increase the overall tensile performance and strength of the sewing thread.

[0025] Reference Figure 3-5 A bobbin of tensile sewing thread comprises a winding rod 6, the outer surface of which is fixedly connected with a positioning block 7, the height of the positioning block 7 is equal to the height of the winding rod 6; a positioning hole 8 is provided on the outer surface of the positioning block 7, the positioning hole 8 is convenient for the sewing thread to pass through, and one end of the sewing thread can be tied in the positioning hole 8 for fixing, a winding groove 9 is provided on the outer surface of the positioning block 7, the above-mentioned tensile sewing thread is wound on the positioning block 7, the winding groove 9 is convenient for the sewing thread to be tightly wound around the surface of the positioning block 7, and a limiting circular block 10 is detachably installed on the outer surface of the winding rod 6, the number of the limiting circular blocks 10 is two, and the two limiting circular blocks 10 are symmetrically distributed with the winding rod 6 as the center.

[0026] Reference Figure 3-5A support block 11 is fixedly connected to one side of the limiting circular block 10 away from the winding rod 6. There are ten support blocks 11 and they are evenly divided into two groups. A single group of support blocks 11 is distributed in a circular array with a single limiting circular block 10 as the center.

[0027] Reference Figure 3-5 A round handle 12 is fixedly connected to the side of the limiting circular block 10 away from the winding rod 6. The round handle 12 is installed in the central part of the surface of the limiting circular block 10. The height of the round handle 12 is less than the height of the supporting block 11. The operator holds the round handle 12 to drive the limiting circular block 10 to rotate. The outer surface of the round handle 12 is provided with a plurality of anti-skid particles 13, and the provision of the anti-skid particles 13 can increase the friction force on the surface of the round handle 12, which is beneficial for the operator to stably control the rotation of the round handle 12.

[0028] Reference Figure 3-5 A threaded hole 14 is provided on the outer surface of the winding rod 6, and a threaded rod 15 is welded on the side of the limiting block 10 close to the winding rod 6. The threaded rod 15 is threadedly connected to the inner cavity of the winding rod 6. When the operator rotates the limiting block 10 counterclockwise through the round handle 12 and the anti-slip particles 13, the limiting block 10 is forced to move in the direction away from the winding rod 6. After the threaded rod 15 is completely disengaged from the threaded hole 14, the fixed state of the limiting block 10 and the winding rod 6 is released, and the operator can quickly disassemble and replace the limiting block 10 as a whole.

[0029] Working principle: First, multiple sub-threads 2 are equidistantly distributed on the surface of the main thread 1 to increase the overall strength of the sewing thread. At the same time, a filling layer 3 is provided on the surface of the sub-thread 2. The material of the filling layer 3 is bamboo charcoal fiber. The bamboo charcoal fiber has the characteristics of moisture absorption, breathability, antibacterial and antibacterial. In addition, a plurality of tensile wires 4 are spirally wound on the outer surface of the filling layer 3. The tensile wire 4 is made of nylon fiber, which can further enhance the tensile properties of the sewing thread. In addition, a fireproof layer 5 is provided on the outer surface of the tensile wire 4. The material of the fireproof layer 5 is basalt fiber. Basalt continuous fiber not only has high strength, but also has the characteristics of electrical insulation, corrosion resistance and high temperature resistance. At the same time, when the sewing thread needs to be wound around the surface of the winding rod 6, the operator can first hold one end of the sewing thread and pass it through the positioning hole 8 on the surface of the positioning block 7 to fix it, and then the operator can pass the sewing thread through the positioning hole 8 and the winding groove 9 to tightly wind it around the surface of the winding rod 6 for short-term storage. At the same time, the two limiting round blocks 10 on the outer surface of the winding rod 6 can be removed and replaced when they are damaged. The operator can hold the round handle 12 and the anti-slip particles 13 to drive the limiting round block 10 to rotate, and the limiting round block 10 can move away from the winding rod 6 when it is forced to rotate counterclockwise. When the threaded rod 15 is completely disengaged from the threaded hole 14, the fixed state of the winding rod 6 and the limiting round block 10 is released, and the operator can quickly disassemble and replace the damaged limiting round block 10.
