Description

Technical Field

[0001] The invention relates to the technical field of antibacterial treatment of textiles, and in particular to a process and equipment for inhibiting bacteria and mildew of textiles by utilizing a magnetic field. Background Art

[0002] There are two existing methods for antibacterial treatment of textiles:

[0003] The first is to add antibacterial agents during the dyeing or weaving process of textiles. Common antibacterial agents include silver ions, copper ions, zinc ions, etc.; the second is to use materials that have certain antibacterial capabilities, such as hemp, bamboo fiber or polylactic acid.

[0004] The first method requires adding an antimicrobial agent to the normal textile production process. While increasing the production process, the original cost of the antimicrobial agent is also increased. The second method, the limitations of the material's own performance will affect the quality and performance of the finished textile products, and cannot meet the requirements of textiles with different properties. In addition, the first and second methods require antibacterial treatment before or during the production of textiles, which will be more troublesome for finished or packaged textiles, and even antibacterial treatment cannot be performed.

[0005] Therefore, there is a need for an antibacterial treatment device that can quickly perform antibacterial and mildew-proof treatment on various types of textiles. Most of the existing antibacterial treatment technologies for textiles require the addition of antibacterial ingredients such as silver ions, copper ions, and zinc ions, either during dyeing and finishing or during spinning; or the use of fibers that have certain antibacterial functions such as hemp, bamboo fiber, polylactic acid, etc. Summary of the invention

[0006] The purpose of the present invention is to provide a process and equipment for inhibiting bacteria and mildew of textiles by using a magnetic field. By placing the textiles in a magnetic field, the paramagnetism of the fiber molecules in the textiles is changed, thereby improving the far-infrared reflection ability and negative ion ionization ability of the textiles, and further improving the antibacterial and mildew-proof ability.

[0007] In order to achieve the above-mentioned invention object, the present invention adopts the following technical scheme: a process for antibacterial and mildew-proofing of textiles using a magnetic field, wherein the textile to be treated is placed in the magnetic field, and after the textile is left stationary in the magnetic field to be magnetized and generate paramagnetism, the textile is taken out of the magnetic field to complete the antibacterial and mildew-proofing treatment; the time from the textile entering the magnetic field to the time the textile is taken out of the magnetic field after the treatment is completed is the treatment period, and during the treatment period, the direction of the magnetic field does not change.

[0008] Preferably, the magnetic field is generated by a powered coil, and the coil is wound by a single strand or multiple strands of continuous insulated wire. The coil is connected to a power supply end, and the power supply end adopts a DC power supply or a pulsed DC power supply. The voltage range of the power supply end is 3V to 5000V, and the pulse frequency of the power supply end is 0Hz to 1MHz. The duration of the treatment period ranges from 1 second to 6 hours, and the duration of the treatment period is inversely proportional to the strength of the magnetic field. The stronger the magnetic field strength, the shorter the duration required for the treatment period.

[0009] Preferably, the textile comprises one or more of textile raw materials, grey fabrics, finished raw materials or finished clothing.

[0010] In order to achieve the above-mentioned invention objectives, the present invention adopts the following technical scheme: a device that uses a magnetic field to inhibit bacteria and mildew on textiles, adopts the above-mentioned process, and the device includes a bracket, a coil for generating a magnetic field and a control circuit board, the magnetic field generator is arranged on the bracket, the control circuit board includes a magnetic field control module, the magnetic field generator and the magnetic field control module are interconnected, and a cavity for placing textiles is provided in the coil.

[0011] Preferably, the bracket includes an outer frame and an inner frame, the inner frame is located inside the outer frame, and the cavity is arranged on the inner frame; the coil is wound on the inner frame, and the coil is located between the outer frame and the inner frame.

[0012] Preferably, the inner frame is made of non-metallic material, and the outer frame is made of metallic material.

[0013] The inner frame is made of non-metallic material, which can ensure that the generated magnetic field is evenly distributed in the cavity and better act on the textiles; the outer frame is made of metal material, which can confine most of the magnetic field generated by the coil to the inside of the machine, preventing the strong magnetic field from spreading outward and affecting other equipment.

[0014] Preferably, the coil is connected to a power supply end, and the power supply end includes a power supply, a boost circuit and an energy storage circuit connected in sequence.

[0015] The magnetic field acting on the textile can adjust the electromagnetic intensity and time according to actual needs. The boost circuit can provide the required voltage for the coil; when the boost circuit is boosting, the commonly used mains electricity cannot meet the demand, so the energy storage circuit is needed to store electrical energy to ensure that the boost circuit and the coil can meet the needs of generating a specific magnetic field.

[0016] Preferably, the energy storage circuit is composed of a single or multiple capacitors; the boost circuit is composed of a transformer plus a rectifier circuit, or a voltage doubling circuit composed of a capacitor and a diode.

[0017] Compared with the prior art, the process and equipment for using magnetic field to inhibit bacteria and mildew on textiles using the above technical solution has the following beneficial effects:

[0018] 1. Compared with adding antibacterial agents (such as silver ions) to fabrics, the process of using a magnetic field to inhibit bacteria and mildew on textiles according to the present invention can ensure that the fabric retains a certain degree of antibacterial properties after multiple washings. It is suitable for fabrics that need to be inhibited for a short period of time. This process can effectively reduce the cost of raw materials.

[0019] Second, there is no need to add other antibacterial process steps in the production of textiles. Since the magnetic field is a single-direction magnetic field, the fabric can quickly generate paramagnetism. There are currently two ways to generate a magnetic field. The first is a permanent magnet magnetic field, which requires the fabric to stay in the magnetic field for a long time to weaken its anti-magnetism to generate paramagnetism. The second is an electromagnetic field, that is, an electromagnetic field is generated by an electric current, and a strong magnetic field in a single direction is used to magnetize the internal fabric to generate paramagnetism; if the magnetic field strength is increased, the magnetization time can be adaptively shortened.

[0020] 3. In the preferred embodiment of the present invention, the magnetic field is continuously or pulsedly supplied by a DC power supply. When DC power is supplied, the magnetic field generated is a single-direction magnetic field, which can form paramagnetism on the fabric. If AC power is used or the direction of the current changes, the paramagnetism of the fabric is easily offset. Therefore, DC power supply is adopted in the present invention.

[0021] Fourth, in the preferred embodiment, the DC power supply of the magnetic field adopts low-frequency pulse power supply, which can form a unidirectional pulse magnetic field. The fabric itself is a non-metallic object with certain anti-magnetism. When continuous power supply or high-frequency pulse power supply is used, the magnetic field generated is also a constant magnetic field or a high-frequency variable magnetic field. Therefore, the magnetization behavior will form a dynamic balance with the anti-magnetism of the fabric, making it difficult for the paramagnetism of the fabric to be quickly superimposed. However, when a low-frequency pulse magnetic field is used, a large magnetic field is released instantly and gradually weakened, which can avoid the formation of dynamic balance during the magnetization process. Through multiple pulse magnetic field magnetization, the fabric can produce paramagnetism. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0047] The present invention is further described below in conjunction with the accompanying drawings.

[0048] The invention discloses a process for inhibiting bacteria and mildew on textiles by using a magnetic field. The textiles to be treated are placed in the magnetic field. After the textiles are left stationary in the magnetic field to be magnetized and generate paramagnetism, the textiles are taken out of the magnetic field to complete the antibacterial and mildew-proof treatment. The time from when the textiles enter the magnetic field to when they are taken out of the magnetic field after the treatment is completed is the treatment period. During the treatment period, the direction of the magnetic field does not change.

[0049] The magnetic field is generated by a coil with electricity, and the coil is wound by a single or multiple strands of continuous insulated wire.

[0050] The coil is connected to a power supply end, which adopts a DC power supply or a pulsed DC power supply. The voltage range of the power supply end is 3V to 5000V, and the pulse frequency of the power supply end is 0Hz to 1MHz. Under the above voltage state, the instantaneous electromagnetic field strength generated by the coil is 0.0001T-10T (i.e. 1Gs-100000Gs). Among them, the duration of the treatment period ranges from 1 second to 6 hours, and the length of the treatment period is inversely proportional to the strength of the magnetic field. The stronger the magnetic field strength, the shorter the duration required for the treatment period. Follow the magnetic induction intensity formula B=N(μI / 2πr): the number of turns of the coil changes the magnetic induction intensity of the generated magnetic field. The more turns, the stronger it is, the smaller the resistance, the larger the current, and the smaller the coil diameter. Similarly, it also follows W=1 / 2CU2: the larger the capacitance and the higher the voltage, the greater the output energy and the shorter the processing time.

[0051] The process and equipment in this embodiment are used to treat textiles. The textiles do not need to be unpacked and are subjected to the magnetic field generated by electric field discharge in the cavity, which changes the paramagnetism of the product fiber molecules, improves the far-infrared reflection ability, negative ion ionization ability, etc., thereby showing comprehensive antibacterial ability. The equipment can realize unattended automatic detection of material in and out and automatic operation. The entire textile antibacterial treatment process can be completed in about 30 seconds, and the antibacterial rate of GB / T20944 Staphylococcus aureus can still reach 99% after washing 50 or even 200 times.

[0068] Embodiment 6:

[0069] like Figures 1 to 5 The device for inhibiting bacteria and mildew of textiles by using magnetic field shown in the figure comprises a support 1, the support 1 comprises an outer frame 11 and an inner frame 12, the inner frame 12 is located inside the outer frame 11, a coil 20 for generating a magnetic field by powering is wound on the inner frame 12, and the coil 20 is located between the outer frame 11 and the inner frame 12. The coil 20 is wound by winding a single strand or multiple strands of continuous skin insulated wire, and the winding width of the coil 20 is greater than the width of the textile 7 entering the cavity 21.

[0070] The coil 20 is the magnetic field generator in this embodiment. In the actual production process, other methods can also be used to replace the coil 20 as the magnetic field generator. For example, a permanent magnet can also be used as the magnetic field generator.

[0071] The inner frame 12 is provided with a cavity 21 for placing the textile 7, and both ends of the cavity 21 are connected to the outside. A conveying mechanism 4 is provided in the cavity 21, and the conveying mechanism 4 includes a conveying frame 41 and a conveyor belt 42. The conveying frame is arranged at both ends of the cavity 21, and the conveyor belt is fixed on the conveying frame 41. The textile 7 moves from one end of the cavity 21 to the other end of the cavity 21 driven by the conveyor belt 42. Among them, the conveying frame 41 and the conveyor belt 42 can adopt the common conveying wheel and belt structure, and can adopt other structures that can achieve the same conveying purpose.

[0072] The two ends of the cavity 21 are respectively a feed port and a discharge port. The end where the textile to be treated with antibacterial agents enters the cavity 21 is the feed port, and the end where the textile to be treated with antibacterial agents exits the cavity 21 is the discharge port. Both the discharge port and the feed port are provided with position sensors 5 for detecting the position of the textile.

[0073] In order to ensure that the magnetic field generated by the coil 20 can better act on the textile 7, the inner frame 12 is made of non-metallic material and the outer frame 11 is made of metallic material.

[0074] The antibacterial treatment device of this embodiment further includes a control circuit board 3, which includes a magnetic field control module 31, a central control module 32, a sensor module 33 and a transmission control module 34. Figure 4 As shown, the magnetic field control module 31, the transmission control module 34 and the sensor module 33 are respectively connected to the central control module 32, wherein the central control module 32 adopts PLC control technology.

[0075] The magnetic field control module 31 is connected to the coil 20 and is used to charge and discharge the coil 20 to control the strength of the generated magnetic field. The magnetic field control module 31 includes a tank circuit 311 and a boost circuit 312. The tank circuit 311 is composed of a single or multiple capacitors; the boost circuit 312 can be a voltage doubler circuit composed of a transformer plus a rectifier module or a capacitor diode. The boost circuit 312 and the tank circuit 311 are added to provide a sufficiently large voltage to the coil 20, so that better processing effects can be achieved in a shorter time.

[0076] In this embodiment, the power supply, the boost circuit 312, and the energy storage circuit 311 together constitute the power supply end for providing electrical energy to the coil 20, wherein the power supply increases the voltage through the boost circuit 312, and pre-stores the electrical energy in the energy storage circuit 311 (high-voltage capacitor), and then the energy storage circuit 311 releases the electrical energy instantaneously, generates an extremely high current in a short time, and forms an instantaneously large magnetic field through the coil 20.

[0077] The transmission control module 34 is connected to the conveying frame 41 in the conveying mechanism 4 and is used to control the start and stop of the conveying frame 41 to achieve the purpose of controlling the conveyor belt 42 and ultimately control the position of the textile 7 relative to the magnetic field in the cavity 21 .

[0078] The sensor module 33 is connected to the position sensor 5 on the outer frame 11. The position sensor 5 is used to sense the position of the textile 7 on the conveyor belt 42 to determine whether the textile 7 is located in the cavity 21, thereby cooperating with the charging and discharging of the coil 20 to achieve the purpose of automatically generating a magnetic field.

[0079] The information of the above modules and connected components is received and processed by the central control module 32. The detailed process is as follows:

[0080] The antibacterial treatment device is powered on, the position sensor 5 monitors the position of the items on the conveyor belt 42, and sends the monitored position information to the central control module 32. The central control module 32 determines whether the textile 7 is located in the cavity 21 based on the received position signal.

[0081] In order to make the position monitoring of the textile 7 more accurate, position sensors 5 are provided at the feed port and the discharge port of the cavity 21. When the central control module 32 determines that the textile 7 is located in the cavity 21, the central control module 32 sends instructions to the magnetic field control module 31 and the transmission control module 34 at the same time, the magnetic field control module 31 charges the coil 20 to generate a magnetic field, the transmission control module controls the transmission frame 41 to stop running, and the conveyor belt 42 stops running at this time, and the textile 7 is located in the cavity 21 waiting for the magnetic field antibacterial treatment.

[0082] After a certain antibacterial treatment time has passed, the central control module 32 sends instructions to the magnetic field control module 31 and the transmission control module, the magnetic field control module 31 stops charging the coil 20, and the transmission control module 34 controls the transmission rack 41 to continue working to transport the antibacterial treated textiles out of the cavity 21. At this time, the position sensor 5 continues to work, and after monitoring that a new textile 7 enters the cavity 21, the above steps are repeated to realize automated batch antibacterial treatment.

[0083] The textile 7 includes one or more of textile raw materials, grey fabrics, finished raw materials or finished clothing. A plurality of charging antibacterial treatment modes are preset in the magnetic field control module 31 to ensure that different textiles 7 can obtain the best magnetic field antibacterial treatment method. In this embodiment, a control panel 6 is provided on the outer frame 11, and the control panel 6 is connected to the central control module 32 for sending user instructions to the central control module 32. The user can individually control the antibacterial treatment device through the control panel 6 to achieve the desired working effect.

[0115] Embodiment 12:

[0118] See also Fig. 9As shown, this embodiment uses a constant magnetic field of a permanent magnet to replace the electromagnetic field. When in use, a frame is set up on the conveyor belt, and a channel for the conveyor belt to pass through is reserved in the middle of the frame. The height of the channel is less than 30 mm, and permanent magnets are fixed on the upper and lower frame surfaces of the channel to ensure that a constant magnetic field of not less than 0.5 T is applied in the channel, so that the fabric is magnetized when the fabric passes through.

[0119] Because the farther the distance between the two permanent magnets is, the smaller the magnetic field in the middle is, after controlling the height of the channel, the antibacterial treatment equipment is currently only suitable for the passage of thinner and smaller fabrics (such as socks, gloves, sleeves, etc.).

[0120] The above is only a preferred embodiment of the present invention, which proves that the antibacterial properties of textiles of different materials are directly related to the magnetic induction intensity and the treatment time. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
