Description

Technical Field

[0001] The invention relates to the technical field of production of colored linen-like polyester fibers, and in particular to a system and method for producing colored linen-like polyester fibers. Background Art

[0002] The production of Yangdi colored imitation linen silk uses cationic POY and semi-gloss POY as raw materials, and is compounded with colored polyester through a unique drawing false twist texturing process. This product fully combines the synergistic advantages of cationic easy dyeing and colored polyester fiber color matching, and after processing through a unique process, the product also has the feel of linen. It is mainly used for high-end curtains, clothing fabrics, etc. The false twist texturing process adopts a physical processing method. Through the mechanical and thermal effects of the false twist texturing machine, thermoplastic artificial fibers (such as polyester, nylon, acrylic, etc.) are processed to give them appearance differences, physical properties differences, dyeing properties differences, etc.

[0003] However, during actual use, the inventors found that when the false twister was used for a long time, the first polyurethane disc rubbed against the silk thread, causing an obvious dividing line to appear at the bottom of the disc. Due to the continuous friction between the silk thread and the disc and the partial contact between the silk thread and the disc, the disc was cut, causing the size of its lower part to become smaller. The wear of the lower part of the disc caused the contact surface between the silk thread and the disc to change. When the wear reaches a certain extent, the silk thread is not sufficiently gripped, tension fluctuations occur, and technical problems such as intermittent stiff wire occur. Summary of the invention

[0004] The purpose of the present invention is to address the deficiencies of the prior art. By setting up a repair mechanism, the tangent position of the disc and the wire is kept basically consistent during operation, thereby solving the technical problem that the disc is worn to a certain extent, the wire is not sufficiently gripped, tension fluctuates, and intermittent stiff wire is produced.

[0005] In view of the above technical problems, the following technical solutions are adopted: a positive polyester colored imitation linen silk production system includes a deformation hot box, a cooling device, a false twisting device, a shaping hot box, an oiling device, a friction roller, a winding device and a plurality of roller devices distributed between the devices, the false twisting device includes a repair mechanism arranged on the false twister and used to trim itself during the false twisting process to ensure the false twisting effect, a maintenance mechanism arranged on the repair mechanism and used to clean the hair scraps during the false twisting process, and a cooling mechanism arranged on the repair mechanism and used to cool the repair mechanism;

[0006] First, POY passes through the zero roller and the second roller into the deformation hot box, passes through the cooling device and the false twisting device, is transported by the second roller into the shaping hot box, and then is transported by the four and three rollers into the oiling device and the friction roller. After the winding preparation, the DTY finished product is obtained. During the false twisting process, the repair mechanism cooperates with the false twister to false twist the silk thread. At the same time, the repair mechanism trims its own worn parts, and the maintenance mechanism eliminates dandruff in front of the repair mechanism. In addition, the cooling mechanism will keep the temperature of the twisting position inside the repair mechanism constant during the entire working process.

[0007] A method adapted to a Yangdi colored linen-like silk production system comprises the following steps:

[0008] Step 1: Cleaning process. After being stretched by rollers and deformed by deformation hot box, POY reaches the false twisting device. Then, false twisting is performed under the joint action of false twister and repair mechanism. During the process, when the disc rubs against the silk thread, static electricity will be generated on the disc and then the hair scraps will be adsorbed. At this time, under the action of maintenance mechanism, static electricity is first removed from the hair scraps and the corresponding position of the disc through static electricity removal component, and then the hair scraps are separated from the disc under the action of hair scrap removal component.

[0009] Step 2, repair process, during the false twisting process, the lower part of the disc is seriously worn due to the continuous friction between the disc and the silk thread, and the false twisting effect is greatly different at this time. Then, during the rotation of the disc, the second propulsion assembly will grind the disc to ensure that the outer circumference shape of the disc remains in the initial state;

[0010] Step 3, a compensation process, at the same time, due to the loss of disc material, under the action of the first propulsion assembly, the edge of the disc moves forward, so that the false twist position of the disc and the silk thread can remain unchanged;

[0011] Step 4, temperature control process. During the false twisting process, the cooling mechanism passes circulating water into the disc, thereby eliminating the heat generated by the friction between the disc and the silk thread in time, so that the temperature of the disc itself remains constant. The lower temperature will also better maintain the hardness of the disc and extend its service life. Finally, it is shaped in a shaping hot box to complete the collection of DTY.

[0012] Preferably, the temperature of the deformation hot box is between 210°C and 220°C.

[0013] Preferably, the temperature of the shaping hot box is 15°C to 30°C lower than the temperature of the deformation hot box.

[0014] Preferably, the POY springing speed is between 500 m / min and 700 m / min.

[0015] Preferably, the draft ratio of the POY is between 1.5 and 1.7.

[0016] Preferably, the false twist ratio of the POY is between 1.3 and 1.7.

[0017] Preferably, the second overfeed ratio of POY is between 2% and 4%.

[0018] Preferably, the crystallinity of the DTY is between 39% and 41%.

[0019] Preferably, the dyeing uniformity of the DTY is greater than or equal to level 4.

[0020] Beneficial effects of the present invention:

[0021] (1) In the present invention, by providing a twisting component and a second propulsion component in the repair mechanism, the upper and lower parts of the outer surface of the first polyurethane disc are polished by the second propulsion component and the silk thread respectively during use, thereby ensuring the dynamic balance of the outer peripheral shape of the disc and solving the technical problem that the silk thread partially contacts the disc, thereby cutting the disc and reducing the size of its lower part, and the wear of the lower part of the disc causes the contact surface between the silk thread and the disc to change;

[0022] (2) In the present invention, by providing a twisting assembly and a first propulsion assembly in the repair mechanism, the disc after being polished by the second propulsion assembly can move forward a certain distance, thereby ensuring the constant false twist position of the silk thread, improving the false twist effect, and solving the technical problem of the contact position deviation between the silk thread and the disc due to edge shrinkage after polishing the upper and lower circumferential positions of the disc;

[0023] (3) In the present invention, a cooling mechanism is provided to circulate cooling water inside the first polyurethane disc, thereby timely eliminating the heat generated by the friction between the silk thread and the disc. The lower temperature can better maintain the hardness of the false twister disc, thereby increasing the service life of the disc.

[0024] (4) In the present invention, by providing a static electricity removal component and a hair debris removal component in the maintenance mechanism, static electricity is eliminated in time to separate hair debris from the disc, thereby solving the technical problem that static electricity will occur when hair debris is generated due to friction between the silk thread and the disc. At this time, hair debris is adsorbed on the disc due to static electricity, affecting subsequent polishing work and reducing the quality of silk thread production.

[0025] In summary, the equipment has the advantages of balanced overall quality of false twisting of silk threads, long service life of false twister discs, and less hair on the surface of silk threads. It is particularly suitable for the technical field of production of positive polyester colored imitation linen silk. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0039] Embodiment 1

[0040] like Figures 1 to 3As shown, a positive polyester colored imitation linen silk production system includes a deformation hot box, a cooling device, a false twisting device, a shaping hot box, an oiling device, a friction roller, a winding device and a plurality of roller devices distributed between the devices, wherein the false twisting device includes a repair mechanism 1 arranged on a false twister 100 and used to trim itself during the false twisting process to ensure the false twisting effect, a maintenance mechanism 2 arranged on the repair mechanism 1 and used to clean the hair scraps during the false twisting process, and a cooling mechanism 3 arranged on the repair mechanism 1 and used to cool the repair mechanism 1;

[0041] First, POY passes through the zero roller and the second roller into the deformation hot box, passes through the cooling device and the false twisting device, is transported by the second roller into the shaping hot box, and then is transported by the four and three rollers into the oiling device and the friction roller, and is prepared into a DTY finished product through packaging. During the false twisting process, the repair mechanism 1 cooperates with the false twister 100 to false twist the silk thread, and at the same time, the repair mechanism 1 trims its own worn parts, and the maintenance mechanism 2 eliminates dander in front of the repair mechanism 1, and the cooling mechanism 3 keeps the temperature of the twisting position inside the repair mechanism 1 constant during the entire working process.

[0042] In this embodiment, by setting the main parameters in the process including: texturing speed, first hot box temperature, draft ratio, false twist ratio, second overfeed rate, second hot box temperature, etc., the product DTY has excellent performance through a unique drafting and false twisting texturing process, and the service life of the false twist device is extended, further improving the product experience.

[0043] Embodiment 2

[0044] like Figure 1 to Figure 2 As shown, the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0045] like Figure 1 to Figure 2 As shown, a method adapted to a Yangdi colored imitation linen silk production system comprises the following steps:

[0046] Step 1, cleaning process, after being stretched by rollers and deformed by deformation hot box, POY reaches the false twisting device, and then false twisting is performed under the joint action of false twister 100 and repair mechanism 1. During the process, when disc 115 rubs against the silk thread, static electricity will be generated on disc 115, and then hair scraps will be adsorbed. At this time, under the action of maintenance mechanism 2, static electricity at the corresponding position of hair scraps and disc 115 is first removed by static electricity removal component 21, and then hair scraps are separated from disc 115 under the action of hair scrap removal component 22;

[0047] Step 2, repair process, during the false twisting process, the lower part of the disc 115 is seriously worn due to the continuous friction between the disc 115 and the silk thread, and the false twisting effect is greatly different at this time. Then, during the rotation of the disc 115, the second propulsion assembly 13 will grind the disc 115 to ensure that the outer circumferential shape of the disc 115 remains in the initial state;

[0048] Step 3, compensation process, at the same time, due to the loss of the disc 115 material, under the action of the first propulsion assembly 12, the edge of the disc 115 moves forward, so that the false twist position of the disc 115 and the silk thread can remain unchanged;

[0049] Step 4, temperature control process, during the false twisting process, the cooling mechanism 3 passes circulating water into the disc 115, thereby eliminating the heat generated by the friction between the disc 115 and the silk thread in time, so that the temperature of the disc 115 itself remains constant. The lower temperature will also better maintain the hardness of the disc 115, extending its service life, and finally it is shaped and collected in a shaping hot box.

[0050] Further, if Figure 1 As shown, the temperature of the deformation hot box is between 210°C and 220°C.

[0051] In this embodiment, as the temperature increases, the movement amplitude of the macromolecular chain increases, and the molecules of different monofilaments are easily intertwined and entangled in the contact parts. The appearance is reflected in the formation of adhesion points, and this process is irreversible. Therefore, the adhesion of the fiber increases with the increase of temperature, the fluffiness of the silk strips will deteriorate, but the numbness will be more obvious; at 210°C, the color point distribution of the garters is relatively uniform, and the production stability is better. When it reaches 220°C, although the distribution of color bands and color spots is more regular, the feel is already hard, the fluffiness of the silk strips is very poor, and the whole silk is rigid; therefore, the deformation temperature should be controlled between 210°C and 220°C.

[0052] Further, if Figure 1 As shown, the temperature of the shaping hot box is 15°C to 30°C lower than the temperature of the deformation hot box.

[0053] In this embodiment, because the fiber is in an incompletely stretched state under low draft ratio and high temperature deformation conditions, in order to avoid curling and shrinkage caused by excessive internal stress during the weaving process, it is also extremely important to control the temperature H2 of the shaping hot box; the degree of thermal relaxation of macromolecules increases with increasing temperature, and the dynamic internal stress also increases accordingly. At the maximum crystallization rate temperature of 180°C, the fiber's curling shrinkage rate begins to decrease and stabilize due to the significant increase in crystallinity, and the fiber morphology will also remain stable; therefore, the shaping hot box temperature is 15°C to 30°C lower than the deformation hot box temperature, which can obtain the best combination of dimensional stability and energy consumption. If the shaping hot box temperature is too high, it will not only fail to shape the DTY yarn, but also cause the fiber macromolecules to de-orient, thereby increasing its elongation at break.

[0054] Further, if Figure 1 As shown, the POY stretching speed is between 500 m / min and 700 m / min.

[0055] In this embodiment, considering the residence time of the yarn in the first hot box and the stability of production, if the speed is too high, the residence time of the yarn in the hot box will be shortened accordingly, the thermoplasticity of the fiber will be reduced, the thermal deformation process will be insufficient, the strength of the yarn will be reduced, and problems of lint and breakage will easily occur.

[0056] Further, if Figure 1 As shown, the draft ratio of the POY is between 1.5 and 1.7.

[0057] In this embodiment, the draft ratio has the most important influence on the linear density and elongation at break of polyester DTY yarn. The draft ratio refers to the speed ratio of the second roller and the first roller. The larger the speed ratio, the stronger the mechanical action on the yarn and the smaller the linear density of the yarn. As the draft ratio increases, the tensile stress on the fiber during thermal deformation increases, the activity of the fiber macromolecular chain increases, the molecular chains re-aggregate and arrange along the fiber axis, and the orientation degree of the molecular chains is improved. Therefore, the amount of stretch that can be stretched during the stretching process is less, and the elongation at break is reduced.

[0058] Further, if Figure 1 As shown, the false twist ratio of the POY is between 1.3 and 1.7.

[0059] In this embodiment, the false twist ratio is set so that the curling degree of the silk thread and the elasticizing effect meet the production requirements, which is beneficial to the subsequent composite spinning, improves the feel of the product after unique processing, and increases the application scenarios of the product.

[0060] Further, if Figure 1 As shown, the second overfeed ratio of the POY is between 2% and 4%.

[0061] In this embodiment, the second overfeed rate has the most important influence on the curl shrinkage rate of the polyester DTY yarn; the second overfeed rate is also called the shaping overfeed rate. As the second overfeed rate increases, the curl shrinkage rate is significantly reduced. The larger the second overfeed rate, the more relaxed the yarn state is, and the smaller the internal stress is, thereby reducing the curl shrinkage rate of the DTY yarn.

[0062] Further, if Figure 1 As shown, the crystallinity of the DTY is between 39% and 41%.

[0063] It is worth mentioning here that the greater the crystallinity and the faster the crystallization speed of polyester DTY yarn, the worse the stability of its dyeing indicators. Under the premise of ensuring stable production, the crystallinity of DTY is between 39% and 41%.

[0064] Further, if Figure 1 As shown, the dyeing uniformity of the DTY is greater than or equal to level 4.

[0065] In this embodiment, the dyeing uniformity of DTY is high, which can make the final product more beautiful and colorful, thereby improving the added value and market competitiveness of the product. In addition, DTY with high uniformity can also improve production efficiency, reduce production costs, and reduce the number of repeated productions to achieve the desired color requirements.

[0066] Embodiment 3

[0067] like Figures 2 to 3 As shown, the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The difference between the third embodiment and the second embodiment is that:

[0068] Further, if Figure 6 As shown, the repair mechanism 1 includes a twisting assembly 11 arranged on the false twister 100 and used for twisting the silk thread, a first propulsion assembly 12 arranged on the twisting assembly 11 and used for driving the twisting assembly 11 to move forward to a certain position, and a second propulsion assembly 13 arranged on the twisting assembly 11 and used for grinding and adjusting the twisting assembly 11.

[0069] It is worth mentioning that by setting up the repair mechanism 1, the disk 115 and the tangent position of the silk thread are kept basically consistent during the working process, thereby solving the technical problem that the disk 115 is worn to a certain extent, the silk thread is not sufficiently gripped, tension fluctuates, and intermittent stiff silk is produced.

[0070] In detail, during the false twisting process, the first propulsion assembly 12 and the second propulsion assembly 13 continuously guide the twisting assembly 11 to perform grinding and position compensation, so that the false twisting effect of the silk thread remains consistent.

[0071] Further, if Figures 3 to 6 As shown, the twisting assembly 11 includes a bracket 111 connected to the false twister 100, a mounting frame 112 connected to the bracket 111, a mounting head 113 connected to the bracket 111 and connected to the mounting frame 112, a first rotating shaft 114 connected to the mounting head 113, a disc 115 connected to one end of the first rotating shaft 114, a motor 116 connected to the mounting frame 112, a second rotating shaft 118 connected to the mounting frame 112 and connected to the output end of the motor 116 through a first belt transmission member 117, and a transmission gear 119 respectively connected to the first rotating shaft 114 and the second rotating shaft 118 and meshing with each other.

[0072] In this embodiment, by providing a disc 115 separated from the main body of the false twister 100, the disc 115 in the twisting assembly 11 replaces the first polyurethane disc 115 in the false twister 100, so that in subsequent work, grinding and position adjustment work can be carried out more conveniently, thereby improving its own service life and ensuring the effect of false twisting of the silk thread.

[0073] In detail, when false twisting starts, the output end of the motor 116 drives the second rotating shaft 118 to rotate through the first belt transmission member 117, and then with the cooperation of two sets of transmission gears 119, the second rotating shaft 118 drives the first rotating shaft 114 to rotate inside the mounting head 113, and the first rotating shaft 114 then drives the disc 115 to cooperate with the false twister 100 to perform false twisting of the silk thread.

[0074] Further, if Figures 3 to 7 and Figure 10 to Figure 11 As shown, the first propulsion assembly 12 includes a third rotating shaft 121 connected to the mounting frame 112, a bevel gear 122 connected to the output end of the motor 116 and the third rotating shaft 121 and meshing with each other, a fourth rotating shaft 124 connected to the mounting frame 112 and connected to a follower gear 123, a driving gear 125 connected to the third rotating shaft 121 and meshing with the follower gear 123, an L-shaped frame 126 connected to the bracket 111, and a first screw rod 127 connected to the L-shaped frame 126 and connected to the fourth rotating shaft 124;

[0075] The second propulsion assembly 13 includes a fifth rotating shaft 131 connected to the mounting frame 112, a second screw rod 132 sleeved on the fifth rotating shaft 131 and connected to the mounting frame 112, a second belt transmission member 133 connected to the fifth rotating shaft 131 and the fourth rotating shaft 124, and a grinding head 134 connected to one end of the second screw rod 132.

[0076] In this embodiment, by setting the twisting component 11 and the second propulsion component 13 in the repair mechanism 1, the upper and lower parts of the outer surface of the first polyurethane disc 115 are polished by the second propulsion component 13 and the silk thread respectively during use, thereby ensuring the dynamic balance of the outer peripheral shape of the disc 115, and solving the technical problem that the silk thread partially contacts the disc 115, thereby causing the disc 115 to be cut, making the lower part of the disc 115 smaller, and the wear of the lower part of the disc 115 causing the contact surface between the silk thread and the disc 115 to change;

[0077] By setting the twisting component 11 and the first propulsion component 12 in the repair mechanism 1, the disc 115 polished by the second propulsion component 13 can move forward a certain distance, thereby ensuring the constancy of the false twist position of the silk thread, improving the false twist effect, and solving the technical problem of edge shrinkage and displacement of the contact position between the silk thread and the disc 115 due to grinding of the upper and lower circumferential positions of the disc 115.

[0078] In detail, during the false twisting process, the silk thread rubs against the lower outer circumference of the disc 115, and the lower outer circumference of the disc 115 is cut after a long time of working. At the same time, the output end of the motor 116 drives the disc 115 to rotate, and the third rotating shaft 121 is synchronously driven to rotate through the bevel gear 122. The third rotating shaft 121 drives the follower gear 123 connected to the fourth rotating shaft 124 to rotate through the driving gear 125. The fourth rotating shaft 124 then drives the first screw rod 127 to rotate and rotates through the L-shaped frame 126. The mounting frame 112 and the disk 115 are pushed to move slowly and continuously; during the process, the fourth shaft 124 drives the fifth shaft 131 to rotate through the second belt transmission member 133, and the fifth shaft 131 drives the second screw rod 132 to rotate. When the second screw rod 132 rotates, it cooperates with the mounting frame 112 to extend itself forward, and then the grinding head 134 at one end of the second screw rod 132 grinds the upper part of the outer circumference of the disk 115, so that the upper and lower parts of the outer circumference of the disk 115 are cut at the same time, and finally the outer circumferential shape of the disk 115 remains unchanged.

[0079] It should be noted that the fifth shaft 131 rotates in place, and the second screw rod 132 is sleeved on the fifth shaft 131 and rotates therewith while slowly moving forward relying on the threaded connection with the mounting frame 112. The connection between the first screw rod 127 and the L-shaped rod and the connection between the second screw rod 132 and the mounting frame 112 can be set to a detachable structure, which is convenient for resetting the first screw rod 127 and the second screw rod 132 when the disk 115 is replaced.

[0080] Further, if Figure 3 and Fig. 9As shown, the maintenance mechanism 2 includes a static elimination component 21 disposed on the twisting component 11 and used to eliminate static electricity on hair debris on the twisting component 11, and a hair debris removal component 22 disposed on the static elimination component 21 and used to collect hair debris in a unified manner.

[0081] In this embodiment, by providing a static electricity removal component 21 and a hair debris removal component 22 in the maintenance mechanism 2, static electricity is eliminated in time to separate hair debris from the disk 115, thereby solving the technical problem that static electricity will occur at the same time as hair debris is generated due to friction between the silk thread and the disk 115. At this time, the hair debris is adsorbed on the disk 115 due to static electricity, affecting subsequent polishing work, reducing the quality of silk thread production, and avoiding static electricity accumulation and possibly causing potential dangers.

[0082] In detail, when the disk 115 carries the hair debris with static electricity to the position of the static electricity removal component 21, the static electricity on the hair debris is eliminated under the action of the static electricity removal component 21, and then the hair debris is separated from the disk 115 under the action of the hair debris removal component 22.

[0083] Further, if Fig. 9 As shown, the static electricity removal assembly 21 includes a collection box 211 connected to the mounting frame 112, a U-shaped frame 213 connected to the collection box 211 through a spring 212, and an static electricity roller 214 connected to the U-shaped frame 213;

[0084] The lint removal assembly 22 includes a cleaning roller 221 connected to the second rotating shaft 118 , a discharge pipe 222 connected to the bottom of the collection box 211 , and a guide blade 223 connected to the end of the second rotating shaft 118 and located in the discharge pipe 222 .

[0085] It is worth mentioning here that, through the action of the spring 212 , the electrostatic roller 214 can maintain close contact with the disc 115 , thereby completely eliminating the static electricity of the hair on the disc 115 . At the same time, the rolling friction between the electrostatic roller 214 and the disc 115 has very little effect on the disc 115 .

[0086] In detail, during the rotation of the disk 115, the electrostatic roller 214 rotates closely against the outer circumference of the disk 115. At this time, the hair debris on the disk 115 will be crushed by the electrostatic roller 214. At the same time, the static electricity on the hair debris is absorbed by the coating on the electrostatic roller 214. Then the second rotating shaft 118 drives the cleaning roller 221 to rotate to sweep the hair debris on the disk 115, and the second rotating shaft 118 drives the guide fan blades 223 to rotate, using wind force to guide the shed hair debris to be collected through the discharge pipe 222.

[0087] It should be noted that, after the disc 115 is polished, the spring 212 drives the U-shaped frame 213 to move, and automatically compensates so that the electrostatic roller 214 maintains contact with the disc 115; the coating on the electrostatic roller 214 is styrene-butadiene rubber, and the electrostatic roller 214 is provided with a grounding wire.

[0088] Further, if Figure 8 As shown, the cooling mechanism 3 includes a pumping box 31 connected to the L-shaped frame 126, a delivery pipe 32 connected between the pumping box 31 and the disk 115, a spiral chamber 33 opened inside the disk 115, a delivery channel 34 opened in the mounting frame 112, the mounting head 113 and the first rotating shaft 114, a row of cooling pipes 35 connected between the delivery channel 34 and the pumping box 31, and a cooling fan blade 36 connected to the third rotating shaft 121.

[0089] In this embodiment, by providing a cooling mechanism 3, cooling water is circulated inside the first polyurethane disc 115, thereby timely eliminating the heat generated by the friction between the silk thread and the disc 115. The lower temperature can better maintain the hardness of the disc 115 of the false twister 100, thereby increasing the service life of the disc 115.

[0090] In detail, during the false twisting process, the pumping box 31 drives the circulating water from the delivery pipe 32 into the spiral chamber 33 inside the disc 115 through power, and then takes away the heat from the outer circumference of the disc 115 during the spiral ascent in the spiral chamber 33, and then reaches the row of cooling pipes 35 through the delivery channel 34 opened in the mounting frame 112, the mounting head 113 and the first rotating shaft 114. At this time, the third rotating shaft 121 drives the cooling fan blades 36 to rotate, cools the circulating water inside the row of cooling pipes 35, and finally the circulating water returns to the inside of the pumping box 31.

2. A method for producing colored linen-like polyester yarn using the system for producing colored linen-like polyester yarn according to claim 1, characterized in that: The following steps are involved: Step 1: Cleaning process. After being stretched by rollers and deformed by deformation hot box, POY reaches the false twisting device. Then, false twisting is performed under the joint action of false twister and repair mechanism. During the process, when the disc rubs against the silk thread, static electricity will be generated on the disc and then the hair scraps will be adsorbed. At this time, under the action of maintenance mechanism, static electricity is first removed from the hair scraps and the corresponding position of the disc through static electricity removal component, and then the hair scraps are separated from the disc under the action of hair scrap removal component. Step 2, repair process, during the false twisting process, the lower part of the disc is seriously worn due to the continuous friction between the disc and the silk thread, and the false twisting effect is greatly different at this time. Then, during the rotation of the disc, the second propulsion assembly will grind the disc to ensure that the outer circumference shape of the disc remains in the initial state; Step 3, a compensation process, at the same time, due to the loss of disc material, under the action of the first propulsion assembly, the edge of the disc moves forward, so that the false twist position of the disc and the silk thread can remain unchanged; Step 4, temperature control process. During the false twisting process, the cooling mechanism passes circulating water into the disc, thereby eliminating the heat generated by the friction between the disc and the silk thread in time, so that the temperature of the disc itself remains constant. The lower temperature will also better maintain the hardness of the disc and extend its service life. Finally, it is shaped in a shaping hot box to complete the collection of DTY.
