Abstract
Description
Technical Field
[0001] This invention relates to the field of textile processing equipment technology, and in particular to a short-process integrated garment processing system that overcomes residual torque. Background Technology
[0002] As living standards improve, people have increasingly higher demands for the comfort and appearance of clothing. Knitted garments are becoming more and more popular due to their good stretchability and comfort. However, the dimensional instability of knitted fabrics, especially the serious problem of skewed loops, affects the further application of knitted fabrics.
[0003] Studies have found that loop skew is mainly caused by residual yarn torque. Generally, the greater the residual yarn torque, the stronger the tendency of the yarn to twist, and the more significant the loop skew in the knitted fabric. During spinning and twisting, the fibers are stretched, bent, and twisted, thus storing corresponding torsional stress in the yarn. Some of this stress is released during spinning or after processing, but a considerable amount remains, forming residual yarn torque.
[0004] Residual torque causes yarns to tend to untwist and release internal torsional stress, which is considered a significant and fundamental cause of dimensional deformation problems such as wale skew in knitted fabrics. Therefore, it is desirable for yarns to have low residual torque, or even eliminate residual torque, to achieve a better fabric appearance. Summary of the Invention
[0005] The purpose of this invention is to provide a short-process integrated garment processing system that overcomes residual torque, addressing the current state of existing technology. This system not only overcomes residual yarn torque, resulting in a better fabric appearance after weaving, but also eliminates the winding process, improving the system's production efficiency. Furthermore, it reduces the residence time of fiber slivers in mid-air, greatly shortening the spinning process and improving spinning efficiency.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A short-process integrated garment processing system for overcoming residual torque includes a drafting mechanism, a twisting mechanism, a transition mechanism, and a weaving mechanism arranged sequentially.
[0008] The drafting mechanism drafts the two rovings at least twice to form two fiber slivers, and then both fiber slivers are fed to the twisting mechanism.
[0009] The twisting mechanism includes a twisting roller group and a yarn guide hook arranged in sequence. The twisting roller group is provided with an upper twisting roller and a lower twisting roller that rotate on their own axis and reciprocate along the axis. Two fiber slivers pass through the twisting roller group, so that the two fiber slivers are falsely twisted to form a primary double-ply yarn. The primary double-ply yarn passes through the yarn guide hook, where the two fiber slivers are untwisted and hug each other to form a secondary double-ply yarn with a positive and negative twist distribution pattern, and then is conveyed to the transition mechanism.
[0010] The transition mechanism adjusts the tension of the secondary double-ply yarn and then conveys the secondary double-ply yarn to the weaving mechanism.
[0011] The weaving mechanism weaves the double-strand yarn into garments according to preset weaving process parameters.
[0012] Furthermore, the drafting mechanism includes a first drafting roller group, a holding roller group, and a second drafting roller group arranged in sequence. The two roving raw materials first pass through the first drafting roller group for opening and initial drafting, then pass through the second drafting roller group for secondary drafting, and then are conveyed to the twisting mechanism.
[0013] Furthermore, the first drafting roll group includes a drafting stripe roll and a drafting pressure roll disposed above the first drafting stripe roll; the gripping roll group includes a gripping stripe roll and a gripping pressure roll disposed above the gripping stripe roll; and the second drafting roll group includes two drafting stripe rolls and two drafting pressure rolls disposed above the second drafting stripe rolls.
[0014] Furthermore, the drafting mechanism also includes a trumpet nozzle, which is arranged on the rear side of a drafting roller group. The trumpet nozzle is used to receive roving raw materials and to bundle two roving raw materials into a drafting roller group respectively.
[0015] Furthermore, a pressure adjustment mechanism is provided between one support of the lower twisting roller and the corresponding support of the upper twisting roller, and a pressure adjustment mechanism is also provided between the other support of the lower twisting roller and the corresponding support of the upper twisting roller. The two pressure adjustment mechanisms are used to adjust the pressure of the fiber sliver between the upper twisting roller and the lower twisting roller.
[0016] Furthermore, the pressure regulating mechanism includes a guide post, a washer, a spring, and an adjusting nut. The guide post passes through the bracket of the lower twisting roller and the corresponding bracket of the upper twisting roller. The lower end of the guide post forms a limit with the bracket of the lower twisting roller. After the lower end of the guide post passes through the corresponding bracket of the upper twisting roller, the washer, spring, and adjusting nut are sequentially installed on the guide post from bottom to top, and the adjusting nut and the guide post are connected by threads.
[0017] Furthermore, the transition mechanism includes a first tension disc, a first tension controller, a second tension controller, and a second tension disc arranged in sequence. The first tension disc rotates clockwise, and the second tension disc rotates counterclockwise. After passing through the first tension disc, the double-strand yarn first winds clockwise around the first tension controller, then winds counterclockwise around the second tension controller, and finally passes through the second tension disc before being output to the weaving mechanism.
[0018] Furthermore, the weaving mechanism is a fully formed circular weft machine.
[0019] The beneficial effects of this invention are as follows:
[0020] 1. In the twisting mechanism of the short-process integrated garment processing system for overcoming residual torque, the upper and lower twisting rollers, which rotate and reciprocate along the axial direction, twist two fiber slivers, giving them false twist to form a primary double-ply yarn. The primary double-ply yarn passes through the yarn guide hook, causing two of the fiber slivers to untwist and interlock, forming a secondary double-ply yarn. Due to the reciprocating twisting of the upper and lower twisting rollers, the positive and negative twists on the secondary double-ply yarn are regularly distributed, while a small untwisted zone is formed between the positive and negative twists. The residual torque inside the secondary double-ply yarn is released in the untwisted zone, thereby overcoming the residual torque of the yarn and achieving a better fabric appearance after weaving.
[0021] 2. In this short-process integrated garment processing system that overcomes residual torque, the yarn is directly conveyed to the weaving mechanism for weaving after being spun out, eliminating the winding process and improving the system's production efficiency.
[0022] 3. In the drafting mechanism of this short-process integrated garment processing system that overcomes residual torque, the roving raw material is drafted at least twice to form a fiber sliver that can participate in spinning, reducing the residence time of the fiber sliver in mid-air, greatly shortening the spinning process and improving spinning efficiency.

Detailed Implementation
[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific examples described herein are merely illustrative and not intended to limit the scope of the invention.
[0030] Please see Figures 1-4 As shown, a short-process integrated garment processing system for overcoming residual torque includes a drafting mechanism 1, a twisting mechanism 2, a transition mechanism 3, and a weaving mechanism 4 arranged in sequence.
[0031] The drafting mechanism 1 drafts the two roving raw materials at least twice to form two fiber slivers, and then conveys both fiber slivers to the twisting mechanism 2.
[0032] In this embodiment, specifically, the drafting mechanism 1 includes a first drafting roller group 101, a holding roller group 102, and a second drafting roller group 103 arranged in sequence. The two roving raw materials first pass through the first drafting roller group 101 for opening and initial drafting, and then pass through the second drafting roller group 103 for secondary drafting, and then are conveyed to the twisting mechanism 2.
[0033] More specifically, the first drafting roller group 101 includes a drafting stripe roller 1011 and a drafting pressure roller 1012 disposed above the first drafting stripe roller 1011; the gripping roller group 102 includes a gripping stripe roller 1021 and a gripping pressure roller 1022 disposed above the gripping stripe roller 1021; and the second drafting roller group 103 includes a second drafting stripe roller 1031 and a second drafting pressure roller 1032 disposed above the second drafting stripe roller 1031.
[0034] In addition, the drafting mechanism 1 also includes a trumpet 104, which is arranged on the rear side of the drafting roller group 101. The trumpet 104 is used to receive roving raw materials and to bundle two roving raw materials into the drafting roller group 101 respectively.
[0035] The twisting mechanism 2 includes a twisting roller group 201 and a yarn guide hook 202 arranged in sequence, which together form a yarn forming triangle area. The twisting roller group 201 is provided with an upper twisting roller 2012 and a lower twisting roller 2011 that rotate and reciprocate along the axial direction. Two fiber slivers pass through the twisting roller group 201, which gives the two fiber slivers false twist to form a primary double-ply yarn. The primary double-ply yarn passes through the yarn guide hook 202, where the two fiber slivers untwist and hug each other to form a secondary double-ply yarn with a positive and negative twist distribution pattern, and then is conveyed to the transition mechanism 3.
[0036] Both ends of the upper twisting roller 2012 and the lower twisting roller 2011 are installed through the bracket 2013. The lower twisting roller 2011 is fixed, and the upper twisting roller 2012 is floating above the lower twisting roller 2011.
[0037] Please see Figure 5 As shown, preferably, a pressure adjusting mechanism 203 is provided between one support 2013 of the lower twisting roller 2011 and the corresponding support 2013 of the upper twisting roller 2012, and a pressure adjusting mechanism 203 is also provided between the other support 2013 of the lower twisting roller 2011 and the corresponding support 2013 of the upper twisting roller 2012. The two pressure adjusting mechanisms 203 are used to adjust the pressure of the fiber sliver between the upper twisting roller 2012 and the lower twisting roller 2011.
[0038] The pressure regulating mechanism 203 includes a guide post 2031, a gasket 2032, a spring 2033, and an adjusting nut 2034. The guide post 2031 passes through the bracket of the lower twisting roller 2011 and the corresponding bracket 2013 of the upper twisting roller 2012. The lower end of the guide post 2031 forms a limit (no relative movement) with the bracket 2013 of the lower twisting roller 2011. After the lower end of the guide post 2031 passes through the corresponding bracket 2013 of the upper twisting roller 2012, the gasket 2032, the spring 2033, and the adjusting nut 2034 are sequentially installed on the guide post 2031 from bottom to top, and the adjusting nut 2034 is threadedly connected to the guide post 2031.
[0039] Specifically, when it is necessary to increase the pressure of the fiber sliver between the upper twisting roller 2012 and the lower twisting roller 2011, simply tighten the adjusting nuts 2034 of the two pressure adjusting mechanisms 203 downwards; when it is necessary to decrease the pressure of the fiber sliver between the upper twisting roller 2012 and the lower twisting roller 2011, do the opposite.
[0040] The transition mechanism 3 adjusts the tension of the secondary double-strand yarn, and then conveys the secondary double-strand yarn to the weaving mechanism 4.
[0041] In this embodiment, specifically, the transition mechanism 3 includes a first tension disc 301, a first tension controller 302, a second tension controller 303, and a second tension disc 304 arranged sequentially. Along the yarn running direction, the first tension disc 301 rotates clockwise, and the second tension disc 304 rotates counterclockwise. After passing through the first tension disc 301, the double-strand yarn first winds clockwise around the first tension controller 302, then winds counterclockwise around the second tension controller 302, and finally passes through the second tension disc 304 before being output to the weaving mechanism 4.
[0042] The weaving mechanism 4 weaves the double-strand yarn into garments according to the preset weaving process parameters.
[0043] In this embodiment, the weaving mechanism 4 is a fully formed circular weft machine.
[0044] More specifically, a fully formed circular knitting machine includes a yarn feeding mechanism, a knitting mechanism, a drafting and crimping mechanism, and a CNC mainboard, among which:
[0045] The yarn feeding mechanism is located in front of the second tension plate 304, which gives the secondary double-strand yarn a certain stretch and transports it to the weaving mechanism to participate in weaving;
[0046] The weaving mechanism is located below the yarn feeding mechanism. As the core mechanism of the fully formed circular knitting machine, it weaves the input secondary double-strand yarn.
[0047] The pulling and winding mechanism is located below the weaving mechanism. It pulls and winds the woven fabric, imparts a certain tension to the fabric, and winds the fabric.
[0048] The CNC motherboard is used to control preset weaving process parameters, thereby adjusting the weaving process.
[0049] The working principle of this invention is as follows:
[0050] The roving material enters the drafting mechanism 1. The two roving materials are respectively bundled by the bell mouth 104 to the first drafting roller group 101. The two roving materials first pass through the first drafting roller group 101 for opening and initial drafting treatment, and then pass through the second drafting roller group 103 for secondary drafting treatment to form two fiber slivers. After that, they are conveyed to the twisting mechanism 2. The holding roller group 102 plays the role of intermediate positioning.
[0051] The fiber slivers enter the twisting mechanism 2. The two fiber slivers pass through the twisting roller group 201, which gives the two fiber slivers false twist to form a primary double-ply yarn. The primary double-ply yarn passes through the yarn guide hook 202, where the two fiber slivers untwist and hug each other to form a secondary double-ply yarn with a positive and negative twist distribution pattern. Then it is conveyed to the transition mechanism 3.
[0052] The secondary double-ply yarn enters the transition mechanism 3, which adjusts the tension of the secondary double-ply yarn and then conveys it to the fully formed circular knitting machine.
[0053] The secondary double-ply yarn enters the fully formed circular knitting machine. The preset weaving process parameters are input on the CNC mainboard. The secondary double-ply yarn is fed into the knitting mechanism by the yarn feeding mechanism and woven according to the preset weaving process parameters. The woven fabric is then wound and collected by the pull-and-take mechanism below.
[0054] The advantages of this invention are as follows:
[0055] In the twisting mechanism of this short-process integrated garment processing system for overcoming residual torque, the upper twisting roller 2012 and the lower twisting roller 2011, which rotate and reciprocate along the axial direction, twist two fiber slivers, giving them false twist to form a primary double-ply yarn. The primary double-ply yarn passes through the yarn guide hook 202, causing two of the fiber slivers to untwist and interlock, forming a secondary double-ply yarn. Due to the reciprocating twisting of the upper twisting roller 2012 and the lower twisting roller 2011, the positive and negative twists are regularly distributed on the secondary double-ply yarn, while a small untwisted zone is formed between the positive and negative twists. The residual torque inside the secondary double-ply yarn is released in the untwisted zone, thereby overcoming the residual torque of the yarn and achieving a better fabric appearance after weaving.
[0056] In this short-process integrated garment processing system that overcomes residual torque, the yarn is directly conveyed to the weaving mechanism 4 for weaving after being spun out, eliminating the winding process and improving the system's production efficiency.
[0057] In the drafting mechanism of this short-process integrated garment processing system that overcomes residual torque, the roving raw material is drafted at least twice to form a fiber sliver that can participate in spinning. This reduces the residence time of the fiber sliver in mid-air, greatly shortens the spinning process, and improves spinning efficiency.
[0058] This invention is not limited to the specific embodiments described above. Those skilled in the art can implement this invention using various other specific embodiments based on the content disclosed herein. Therefore, any design that adopts the design structure and concept of this invention and makes some simple changes or modifications falls within the scope of protection of this invention.
