Description

Technical Field

[0001] This invention relates to the field of synthetic resin technology, specifically to a synthesis system and process for a formaldehyde-free, wrinkle-free finishing resin for textiles. Background Technology

[0002] Formaldehyde-free wrinkle-free finishing resin is a special resin used in textile finishing processes. In traditional textile finishing processes, formaldehyde is often used as a cross-linking agent to achieve wrinkle-free properties. However, formaldehyde is a harmful substance, posing potential risks to human health and the environment. To address this issue, formaldehyde-free wrinkle-free finishing resin has been developed. It is a formaldehyde-free or low-formaldehyde resin used to form a cross-linked structure on the surface of textiles, thereby imparting wrinkle-free and anti-wrinkle properties. The resin is typically synthesized using a reaction vessel. During resin synthesis, the reaction vessel provides a closed reaction environment, allowing control of parameters such as reaction temperature, stirring speed, and time. Depending on the specific synthesis method and reaction conditions, the reaction vessel can conduct different types of reactions, such as polymerization, condensation, and esterification, to achieve resin synthesis.

[0003] For example, Chinese invention patent CN108079929B discloses a resin production system, including a polymerization reactor, a vertical condenser, a horizontal condenser, and a buffer recovery tank. The vertical and horizontal condensers are both shell-and-tube water coolers. The tube side of the vertical and horizontal condensers is supplied with the medium to be cooled, and the shell side of the vertical and horizontal condensers is supplied with cooling water. The polymerization reactor is provided with a feed inlet and a gas outlet. The gas outlet is connected to the tube side inlet of the vertical condenser, the tube side outlet of the vertical condenser is connected to the tube side inlet of the horizontal condenser, the tube side outlet of the horizontal condenser is connected to the inlet of the buffer recovery tank, and the outlet of the buffer recovery tank is connected to the gas outlet.

[0004] However, the aforementioned invention cannot filter out impurity particles in a timely manner during the reaction. During resin production, impurities may form due to incomplete reaction, solid precipitates produced during the reaction, or gel-like substances may form from the polymer during polymerization. These gel-like substances may exist in the reactor as solid particles. If not cleaned promptly, they will affect reaction efficiency and pollute the reactor environment. Especially when polymer gels are present in the reactor, they can provide a surface or structural area for reactant molecules to polymerize. This phenomenon is called the "template effect," where the polymer gel acts as a template or guide, promoting the formation of more polymer. This can lead to the expansion and growth of the polymer gel, forming more solid particles. Failure to remove the polymer gel in a timely manner will result in decreased reaction efficiency and a reduced raw material conversion rate. Summary of the Invention

[0005] To address the technical problem that if polymer gels are not cleaned up in time during resin synthesis, the template effect will cause more resin raw materials to polymerize into polymer gels, resulting in low yield and equipment blockage, this invention provides a synthesis system and process for formaldehyde-free textile wrinkle-free finishing resins to solve the above-mentioned problems.

[0013] As a preferred embodiment of the present invention, the reactor body has an inner liner, and a heating mechanism is provided on the reactor body, the heating mechanism including a hot oil pipe arranged around the inner liner of the reactor body.

[0014] As a preferred embodiment of the present invention, it further includes a vertical fractionating column, a vertical condenser, a horizontal condenser, and a water separator; the reactor lid is provided with an exhaust port, the exhaust port is connected to the input end of the vertical condenser through the vertical fractionating column, the output end of the vertical condenser is connected to the input end of the horizontal condenser, and the horizontal condenser is connected to the water separator; the vertical condenser is provided with a first cooling water inlet and a first cooling water outlet for cooling water to pass through; the horizontal condenser is provided with a second cooling water inlet and a second cooling water outlet for cooling water to pass through.

[0015] A synthesis process for a formaldehyde-free, wrinkle-free finishing resin for textiles, characterized by the following steps: Step A: Add the raw materials for synthesizing formaldehyde-free textile wrinkle-free finishing resin into the main body of the reactor. Flow hot oil into the hot oil pipe to make the temperature inside the main body of the reactor reach the appropriate temperature for the reaction. The DC motor drives the stirrer to work and promote the reaction.

Through the nesting of the connecting rod, the first sleeve and the second sleeve, the position of the stirrer rises. Step D: The filter plate is driven to the top of the reactor body.

Step E: The lifting drive assembly drives the filter plate to descend, and the reaction continues; Step F: After the reaction is completed, the lifting drive assembly drives the filter plate to rise, repeating the filtration of reaction impurities in steps C and D; then the reaction product is discharged from the outlet into the collection container.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] Example 1: Please refer to Figure 1-10 The system shown is a synthesis system for a formaldehyde-free, wrinkle-free finishing resin for textiles. In this embodiment, reference is made to... Figure 1-10 As shown: A synthesis system for a formaldehyde-free, wrinkle-free finishing resin for textiles includes a reaction vessel 100. The reaction vessel 100 includes a barrel-shaped reaction vessel body 110 and a reaction vessel lid 120 for covering the reaction vessel body 110. A stirring device 300 for stirring the interior of the reaction vessel 100 is installed on the reaction vessel 100. The stirring device 300 includes a stirrer 320 driven by a DC motor 310 and is disposed inside the reaction vessel body 110. A filtration mechanism 200 is also installed inside the reaction vessel 100. The filtration mechanism 200 includes a filter plate 210 for filtering particles and condensates. The filter plate 210 has a shape consistent with the horizontal cross-section of the reaction vessel lid 120. The filter plate 210 has filter holes 211 for fluid passage and is disposed parallel to the horizontal plane in the reaction vessel body 110. The filtration mechanism 200 also includes a lifting drive assembly 220 for driving the filter plate 210 to move up and down.

[0024] Specifically, the filter plate 210 is driven to rise by the lifting drive component 220, and the generated resin or reactants in the fluid flow through the filter holes 211. The polymer gel generated by the reaction, unreacted particulate impurities and precipitates are intercepted by the filter plate 210.

[0025] More specifically, glyoxal, urea compounds, buffers, and complexes are added to the reactor body 110. The reaction takes place within the reactor body 110 at a specific pH and temperature to obtain a formaldehyde-free, wrinkle-free resin. A stirring device 300 is used to stir the raw materials within the reactor body 110, promoting the reaction.

[0026] In this embodiment, reference is made to Figure 1-7 As shown, The stirring device 300 also includes a first sleeve 340 with a hollow sleeve structure. The first sleeve 340 is driven and connected to a DC motor 310. The side wall of the first sleeve 340 has a first elongated through hole 341 extending along the axis of the first sleeve 340. The stirrer 320 has a stirring part 321 with stirring function and a connecting rod 323 for connecting the stirring part 321. A first protrusion 324 is provided on the connecting rod 323. The connecting rod 323 is nested in the first sleeve 340, and the first protrusion 324 is engaged in the first elongated through hole 341.

[0027] The stirring device 300 also includes a second sleeve 350 with a hollow sleeve structure. The side wall of the second sleeve 350 has a second elongated through hole 351 extending along the axial direction of the second sleeve 350. The first sleeve 340 is also provided with a second protrusion 342. The first sleeve 340 is nested in the second sleeve 350, and the second protrusion 342 is engaged in the second elongated through hole 351. The second sleeve 350 is driven and connected to the DC motor 310 through a reducer 330.

[0028] Specifically, through the design of the first sleeve 340 and the connecting rod 323, the connecting rod 323 can extend and retract within the first sleeve 340, allowing the stirrer 320 to be raised freely without changing the relative position of the DC motor 310. The three-layer nested structure, with the connecting rod 323 nested within the first sleeve 340 and the first sleeve 340 nested within the second sleeve 350, allows for the raising and lowering of the stirrer 320 without affecting the position of the DC motor 310.

[0029] When the lifting drive assembly 220 drives the filter plate 210 to rise, the filter plate 210 will press against the agitator 320 and push the position of the agitator 320 upward. Through the three-layer nesting of the connecting rod 323, the first sleeve 340 and the second sleeve 350, the agitator 320 has a large vertical displacement stroke space, which ensures the vertical movement position of the filter plate 210 and the agitator 320.

[0030] With the first protrusion 324 and the first elongated through hole 341, the first protrusion 324 can slide up and down in the first elongated through hole 341, and at the same time, it can bear the force transmitted to the connecting rod 323 in the rotational direction when the first sleeve 340 rotates, so as to achieve the effect that the first sleeve 340 can drive the connecting rod 323 to rotate. The second protrusion 342 and the second elongated through hole 351 of the second sleeve 350 have the same effect as the first protrusion 324 and the first elongated through hole 341. They all transmit rotational force without affecting the mutual nesting and sliding of the connecting rod 323, the first sleeve 340 and the second sleeve 350, so that the power transmitted by the DC motor 310 can ultimately drive the stirrer 320 to rotate through the first sleeve 340 and the second sleeve 350.

[0031] The stirring unit 321 can be selected in various styles such as paddle, anchor, and frame according to actual needs. In this embodiment, it is a rotating frame type.

[0032] In this embodiment, reference is made to Figure 7 As shown, An arc-shaped strip 322 is installed at the bottom of the stirrer 320. The arc-shaped strip 322 has an arc-shaped structure and is set in close contact with the filter plate 210.

[0033] Specifically, the function of the arc-shaped strip 322 is to clean the filter plate 210. After the filter plate 210 traps impurities, the agitator 320 rotates while driving the arc-shaped strip 322 to rotate, and the rotation of the arc-shaped strip 322 cleans the filter plate 210.

[0034] In this embodiment, reference is made to Figure 5 , 6 As shown, The top of the reactor body 110 has an impurity storage tank 114 with a top opening around the reactor 100, and the impurity storage tank 114 is connected to the outside of the reactor body 110; the filter plate 210 is surrounded by a scraper edge 212, which is in close contact with the inner wall of the reactor body 110.

[0035] Specifically, the scraper 212 acts as a scraper to clean the inner wall of the reactor body 110. When the filter plate 210 is driven to the top by the lifting drive assembly 220, the arc-shaped strip 322 cleans the filter plate 210, and the cleaned impurities fall along the edge of the filter plate 210 into the impurity storage tank 114. The impurities concentrated in the impurity storage tank 114 are finally flushed away with water.

[0036] In this embodiment, reference is made to Figure 3-6 As shown, The lifting drive assembly 220 includes a slide bar 221 with a linear structure. The lifting drive assembly 220 also includes a linear actuator 222 for driving the slide bar 221 to move up and down. The linear actuator 222 is located below the reactor body 110. The bottom of the reactor body 110 has a transition hole 113 that is clearance-fitted with the slide bar 221.

[0037] Specifically, the linear actuator 222 is a linear motor. Through the clearance fit between the slide rod 221 and the transition hole 113, the resin will not flow down from the transition hole 113, while the up and down movement of the slide rod 221 in the transition hole 113 is not affected.

[0038] When installing the reactor 100, a hole can be dug below the reactor body 110 for installing the linear actuator 222 to reduce the required height of the reactor 100.

[0039] In this embodiment, reference is made to Figure 1-3 As shown, The reactor lid 120 is provided with a feed port 121, the reactor body 110 is provided with a reactor lug 111 on its side wall, and the reactor body 110 is provided with a discharge port 112 at its bottom.

[0040] Specifically, the reactor lug 111 allows the reactor 100 to be installed on factory equipment, and can also be used to install equipment used in conjunction with the synthesis system of formaldehyde-free textile wrinkle-free finishing resin. The feed port 121 is used to add reaction raw materials into the reactor body 110 and to observe the reaction inside the reactor body 110. The discharge port 112 is used to discharge the finished product.

[0041] In this embodiment, reference is made to Figure 5 , 6 As shown, The reactor body 110 has an inner liner, and a heating mechanism 400 is provided on the reactor body 110. The heating mechanism 400 includes a hot oil pipe 410 arranged around the inner liner of the reactor body 110.

[0042] Specifically, the heating mechanism 400 is used to heat the reactor body 110 to provide a suitable temperature for the reaction of the synthetic resin in the reactor body 110. After the reaction of the synthetic resin in the reactor body 110 is completed, the reaction can also be stopped by cooling hot oil through the hot oil pipe 410 to remove heat.

[0043] In this embodiment, reference is made to Figure 1-9 As shown, It also includes a vertical fractionating column 500, a vertical condenser 600, a horizontal condenser 700, and a water separator 820; the reactor lid 120 is provided with an exhaust port 122, which is connected to the input end of the vertical condenser 600 through the vertical fractionating column 500, the output end of the vertical condenser 600 is connected to the input end of the horizontal condenser 700, and the horizontal condenser 700 is connected to the water separator 820; the vertical condenser 600 is provided with a first cooling water inlet 610 and a first cooling water outlet 620 for cooling water to pass through; the horizontal condenser 700 is provided with a second cooling water inlet 710 and a second cooling water outlet 720 for cooling water to pass through.

[0044] Specifically, since the resin synthesis reaction in the reactor body 110 is carried out at high temperatures, distillates are produced. Directly discharging these distillates would cause pollution, and a large amount of raw material would be wasted due to lack of recovery. The vertical fractionating column 500 is used to separate different components in the mixture; it typically consists of a series of packing materials or plates. In the vertical fractionating column 500, the distillate is heated to generate vapor, which is then condensed and liquefied on the packing materials or plates, thus achieving the separation of different components. Subsequently, the vertical condenser 600 and the horizontal condenser 700 condense the vapor into liquid, and finally, the liquid enters the water separator 820 for further separation, completing the recovery of the distillate. Example

[0045] A synthesis process for a formaldehyde-free wrinkle-free finishing resin for textiles, comprising the following steps: Step A: Add the raw materials for synthesizing formaldehyde-free textile wrinkle-free finishing resin into the reactor body 110, and pass hot oil into the hot oil pipe 410 to make the temperature inside the reactor body 110 reach the appropriate temperature for the reaction. The DC motor 310 drives the stirrer 320 to work to promote the reaction. Step B: The distillate generated from the reaction is discharged from the exhaust port 122 and enters the water separator 820 in sequence through the vertical fractionating column 500, the vertical condenser 600 and the horizontal condenser 700. The water separator 820 recovers the distillate generated from the reaction. Step C: When the reaction proceeds to the middle, the reaction generates polymer gel, unreacted particulate impurities and precipitates. At this time, the lifting drive assembly 220 drives the filter plate 210 to rise. The filter plate 210 filters the polymer gel generated by the reaction, the unreacted particulate impurities and precipitates onto the filter plate 210. At the same time, the filter plate 210 lifts the stirrer 320. Through the nesting of the connecting rod 323, the first sleeve 340 and the second sleeve 350, the position of the stirrer 320 rises. Step D: The filter plate 210 is driven to the top of the reactor body 110. At this time, the DC motor 310 drives the stirrer 320 to rotate. The rotation of the stirrer 320 drives the arc strip 322 to rotate. The arc strip 322 sweeps the polymer gel generated by the reaction, the unreacted particulate impurities and precipitates on the filter plate 210 into the impurity storage tank 114. Step E: The lifting drive assembly 220 drives the filter plate 210 to descend, and the reaction continues; Step F: After the reaction is completed, the lifting drive assembly 220 drives the filter plate 210 to rise, repeating the filtration of reaction impurities in steps C and D; then the reaction product is discharged from the outlet 112 into the collection container.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

6. A synthesis process for a formaldehyde-free, wrinkle-free finishing resin for textiles, characterized in that: The synthesis system of the formaldehyde-free textile wrinkle-free finishing resin according to claim 5 is used to achieve this, and includes the following steps: Step A: Add raw materials for synthesizing formaldehyde-free textile wrinkle-free finishing resin into the reactor body (110), and pass hot oil into the hot oil pipe (410) so that the temperature inside the reactor body (110) reaches the appropriate temperature for the reaction. The DC motor (310) drives the stirrer (320) to work to promote the reaction. Step B: The distillate generated from the reaction is discharged from the exhaust port (122) and enters the water separator (820) sequentially through the vertical fractionating column (500), the vertical condenser (600) and the horizontal condenser (700), where the distillate generated from the reaction is recovered. Step C: When the reaction reaches the middle, the reaction generates polymer gel, unreacted particulate impurities and precipitates. At this time, the lifting drive assembly (220) drives the filter plate (210) to rise. The filter plate (210) filters the polymer gel generated by the reaction, the unreacted particulate impurities and precipitates onto the filter plate (210). At the same time, the filter plate (210) lifts the stirrer (320). Through the nesting of the connecting rod (323), the first sleeve (340) and the second sleeve (350), the position of the stirrer (320) rises. Step D: The filter plate (210) is driven to the top of the reactor body (110). At this time, the DC motor (310) drives the stirrer (320) to rotate. The rotation of the stirrer (320) drives the arc strip (322) to rotate. The arc strip (322) sweeps the polymer gel generated by the reaction, unreacted particulate impurities and precipitates on the filter plate (210) into the impurity storage tank (114). Step E: The lifting drive assembly (220) drives the filter plate (210) to descend, and the reaction continues; Step F: After the reaction is completed, the lifting drive assembly (220) drives the filter plate (210) to rise, repeating the filtration of reaction impurities in steps C and D; then the reaction product is discharged from the outlet (112) into the collection container.
