Description

Technical Field

[0001] This invention belongs to the field of down processing technology, specifically relating to a method for preparing antibacterial down with antistatic function and the antibacterial down itself. Background Technology

[0002] Down jackets typically use duck down, goose down, or other types of down as filling. During processing, the down raw materials are usually pre-treated by washing, degreasing, and drying. Then, post-processing is carried out according to requirements. Down has poor electrical conductivity and is prone to generating static electricity.

[0003] The common method for antibacterial and antistatic treatment of down is to use silver ion solution. However, because down is not resistant to high temperatures (such as duck down and goose down, high temperatures will damage the down fibers), drying is generally done at low temperatures. The process is relatively slow, which causes the silver ion solution that has been soaked in the down to gradually drain away. The silver ions leave the down along with the solution, so the antibacterial components of the silver ions cannot be effectively retained in the down. Summary of the Invention

[0004] The purpose of this invention is to provide a method for preparing antibacterial fleece with antistatic function and antibacterial fleece in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: A method for preparing antibacterial down with antistatic function involves treating the cleaned down raw material with a silver ion solution and then drying it. The drying process uses a positive pressure airflow after drying, and the airflow temperature ranges from 15 to 35°C. During the drying process, a drying device is used to repeatedly soak the down raw material with the silver ion solution that has been drained out of the down raw material. The drying device includes an outer shell and a drum mechanism disposed inside the outer shell. The drum mechanism consists of two circular plates forming the end face and several flow storage tank assemblies overlapping end to end to form the circumferential wall of the drum mechanism. The edges of the two circular plates are connected to each other by connectors. The flow storage tank assemblies are rotatably disposed between the circular plates to form a gap at the overlapping part so that airflow can enter and exit the drum mechanism. A flexible filter cover is also disposed between the two circular plates.

[0006] As a further optimization of the present invention, the storage tank assembly includes a storage tank body, which is arc-shaped with a U-shaped cross-section. A shaft is provided on its side surface for rotatable connection with a circular plate. A docking groove is provided between the beginning and end of the storage tank body. By providing the docking groove, the connection between the beginning and end of the storage tank body can be made precise. During the rotation of the roller mechanism, the silver ion solution that is drained flows downward along the storage tank body. The overlapping part of the docking groove overlaps from top to bottom in the flow direction according to the principle of tile overlap, which can prevent the silver ion solution from leaving the storage tank body.

[0007] As a further optimization of the present invention, the roller mechanism is driven to rotate by a motor. One circular plate is used to connect the motor, and the surface of the other circular plate is provided with a second door. A first door is provided on the side surface of the outer shell at a position corresponding to the second door. The door is used to pick up and put down feathers. In order to facilitate picking up and putting down feathers, a corresponding robotic arm can also be provided on the outer shell so that the outer shell can change its posture to change the orientation of the door, which facilitates the picking up and putting down feathers.

[0008] As a further optimization of the present invention, the outer shell is provided with an air inlet slot and an air outlet slot. The reservoir assembly is opened by a telescopic mechanism when passing through the air inlet slot and the air outlet slot. The telescopic mechanism includes a slide rod slidably disposed on the surface of the connector, an abutment disposed at one end of the slide rod for contacting the inner wall of the outer shell, and a spring disposed between the abutment and the connector. The other end of the slide rod is connected to an extension arm disposed on the outer surface of the reservoir body, so that the reservoir body can be rotated by pushing and pulling the extension arm. The structure of the slide rod, the abutment and the spring allows the reservoir assembly to open automatically when it reaches the position of the air inlet slot and the air outlet slot. When the abutment is no longer obstructed, the spring pops out and pulls the reservoir body to rotate, forming a gap. The edges of the abutment and the air inlet slot and the air outlet slot are provided with inclined guide surfaces to facilitate the abutment being abutted again.

[0009] As a further optimization of the present invention, the slide bar is provided with a hinge shaft connected to the extension arm, and the surface of the extension arm is provided with a spiral groove to accommodate the hinge shaft. The hinge shaft and the spiral groove are both sliding and rotating, which facilitates the extension arm to rotate by sliding the slide bar.

[0010] As a further optimization of the present invention, an air inlet hood is provided on the surface of the outer shell corresponding to the air inlet slot, and an air outlet hood is provided on the surface of the air outlet slot, for guiding the airflow.

[0011] As a further optimization of the present invention, the flexible filter cover is arranged in a ring shape on the inner side of the circumferential wall of the roller, and the width of the flexible filter cover is greater than the distance between the two circular plates. When the flexible filter cover is filled with down, it will sink downward and enter the main body of the storage tank, so that the down can be repeatedly soaked in the lost silver ion solution.

[0012] As a further optimization of the present invention, the concentration of the silver ion solution is 0.1-0.5 mol / L, and the treatment method using the silver ion solution is as follows: immerse the down raw material in the silver ion solution and stir for 10-20 minutes, and after the treatment, the drying time is 90-120 minutes.

[0013] The present invention also proposes an antibacterial fleece with antistatic function, which is obtained by the above preparation method.

[0014] The beneficial effects of this invention are as follows: This invention prevents the loss of silver ions during the drying process by repeatedly soaking the down in the drying process. It also features a drum circumferential wall composed of a flow storage tank assembly. During the rolling and air-drying process of the down, the flow storage tank assembly can repeatedly soak the down in the drained solution. After the flow storage tank assembly moves to a predetermined position, it opens, creating a gap to allow the drying airflow to enter, which gradually dries the down. Furthermore, by setting a flexible filter cover on the circumferential wall, it prevents the airflow from carrying away fine down. The airflow entering and exiting through the gap in the flow storage tank assembly allows the flexible filter cover to be recycled. Moreover, the flexible filter cover can be backflushed during air intake to prevent fine down from clogging it. Attached Figure Description

Detailed Implementation

[0016] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0017] Example 1 like Figure 1-5 As shown, a method for preparing antibacterial down with antistatic function involves treating the cleaned down raw material with a silver ion solution and then drying it. The drying process uses a positive pressure airflow after drying, and the airflow temperature is 25°C. During the drying process, a drying device is used to repeatedly soak the down raw material with the silver ion solution that has been drained out of the down raw material. The drying device includes an outer shell 1 and a drum mechanism 2 disposed inside the outer shell 1. The drum mechanism 2 consists of two circular plates 21 forming the end face and several flow storage tank assemblies 3 overlapping end to end to form the circumferential wall of the drum mechanism 2. The edges between the two circular plates 21 are connected to each other by connectors 23. The flow storage tank assemblies 3 are rotatably disposed between the circular plates 21 to form a gap at the overlapping part so that airflow enters and exits into the drum mechanism 2. A flexible filter cover 4 is also disposed between the two circular plates 21.

[0018] This solution utilizes a drum circumferential wall composed of a flow-retaining tank assembly 3. During the down's rolling and air-drying process, the flow-retaining tank assembly 3 repeatedly soaks the down with the dripping silver ion solution. When the flow-retaining tank assembly 3 reaches a predetermined position, it opens, creating a gap to allow the drying airflow to enter. Figure 3 As shown, the roller mechanism 2 rotates clockwise, and the down inside the roller mechanism 2 is higher on the left and lower on the right, and it tumbles continuously. The drained silver ion solution flows continuously in the storage tank assembly 3, soaking the tumbling down. The positive pressure airflow enters the gap of the storage tank assembly 3 in a nearly tangential direction, enters the down through the flexible filter cover 4, and then enters the air outlet hood 14 through other gaps, so that the drying airflow gradually dries the down. In addition, by setting the flexible filter cover 4 on the circumferential wall, it is prevented that the airflow carries away the fine down. The airflow enters and exits through the gap of the storage tank assembly 3. The flexible filter cover 4 plays a part of the filtration during the tumbling process and is recycled. In addition, the flexible filter cover 4 can also be backflushed during air intake to prevent fine down from clogging the flexible filter cover 4.

[0019] The storage tank assembly 3 includes a storage tank body 31, which is arc-shaped with a U-shaped cross-section. A shaft 32 is provided on its side surface to rotatably connect with a circular plate 21. A docking groove 34 is provided between the head and tail of the storage tank body 31. By providing the docking groove 34, the head and tail of the storage tank body 31 can be precisely connected. During the rotation of the roller mechanism 2, the silver ion solution that is drained flows down along the storage tank body 31. The overlapping part of the docking groove 34 overlaps from top to bottom in the flow direction according to the principle of tile overlap, which can prevent the silver ion solution from leaving the storage tank body 31.

[0020] The roller mechanism 2 is driven to rotate by a motor 22. One circular plate 21 is used to connect the motor 22, and the surface of the other circular plate 21 is provided with a second door 24. The side surface of the outer shell 1 is provided with a first door 15 at a position corresponding to the second door 24. The door is used to pick up and put down feathers. In order to facilitate picking up and putting down feathers, a corresponding robotic arm can also be provided on the outer shell 1 so that the outer shell 1 can change its posture to change the orientation of the door, which facilitates the picking up and putting down feathers.

[0021] The outer casing 1 has an air inlet slot 11 and an air outlet slot 13. The reservoir assembly 3 opens through the air inlet slot 11 and the air outlet slot 13 via a telescopic mechanism. The telescopic mechanism includes a slide rod 36 slidably disposed on the surface of the connector 23, an abutment 35 disposed at one end of the slide rod 36 for contacting the inner wall of the outer casing 1, and a spring 37 disposed between the abutment 35 and the connector 23. The other end of the slide rod 36 is connected to an extension arm 33 disposed on the outer surface of the reservoir body 31. The reservoir body 31 is rotated by pushing and pulling the extension arm 33. The structure of the slide rod 36, the abutment 35 and the spring 37 allows the reservoir assembly 3 to open automatically when it reaches the position of the air inlet slot 11 and the air outlet slot 13. When the abutment 35 is no longer obstructed, the spring 37 pops out, pulling the reservoir body 31 to rotate and forming a gap. The edges of the abutment 35, the air inlet slot 11 and the air outlet slot 13 are provided with inclined guide surfaces to facilitate the abutment 35 being abutted again.

[0022] The slide bar 36 is provided with a hinge shaft connected to the extension arm 33. The surface of the extension arm 33 is provided with a loop groove to accommodate the hinge shaft. The hinge shaft and the loop groove are connected by both sliding and rotation. The surface of the outer shell 1 is provided with an air inlet hood 12 corresponding to the air inlet slot 11 and an air outlet hood 14 corresponding to the air outlet slot 13. The flexible filter cover 4 is arranged in a ring shape on the inner side of the circumferential wall of the drum, and the width of the flexible filter cover 4 is greater than the distance between the two circular plates 21.

[0023] The concentration of the silver ion solution was 0.3 mol / L. The treatment method using the silver ion solution was as follows: the down raw material was immersed in the silver ion solution and stirred for 15 minutes. After the treatment was completed, the drying time was 100 minutes.

[0024] The present invention also proposes an antibacterial fleece with antistatic function, which is obtained by the above preparation method.

[0025] Example 2 Unlike Example 1, the airflow temperature was 15°C, the concentration of the silver ion solution was 0.1 mol / L, and the treatment method using the silver ion solution was as follows: the down raw material was immersed in the silver ion solution and stirred for 10 minutes, and the drying time after treatment was 90 minutes.

[0026] Example 3 Unlike Example 1, the airflow temperature was 35°C, the concentration of the silver ion solution was 0.5 mol / L, and the treatment method using the silver ion solution was as follows: the down raw material was immersed in the silver ion solution and stirred for 20 minutes, and the drying time after treatment was 120 minutes.

[0027] Comparative Example 1 In this comparative example, the cleaned down raw materials were treated with a silver ion solution and then dried. The drying process used a conventional drum dryer, with a positive pressure airflow after drying and an airflow temperature of 25°C. The concentration of the silver ion solution was 0.3 mol / L. The treatment method with the silver ion solution was as follows: the down raw materials were immersed in the silver ion solution and stirred for 15 minutes. After the treatment was completed, the drying time was 100 minutes.

[0028] For the down products obtained from the preparation methods of Examples 1-3 and Comparative Example 1, samples were selected for antistatic performance testing. Specifically, the antistatic performance of each down sample was tested according to GB / T 12703.1-2021 "Textiles - Test methods for electrostatic properties - Part 1: Corona charging method", using the electrostatic voltage half-life as the test index. The experimental data are as follows (half-life unit: s): ; The data in the table above leads to the conclusion that, in Examples 1-3, the device was used to repeatedly soak down during the drying process. Although the drying process was slow because high-temperature airflow could not be used, the repeated soaking effect allowed a large amount of the effective antistatic components (silver ions) in the down to be retained, greatly improving the antistatic effect and solving the problem of silver ion loss caused by excessive water draining during the drying process.

[0029] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
