Description

Technical Field

[0001] The invention relates to the technical field of stain-resistant nylon-viscose fabric processing, and in particular to a processing technology and processing equipment for stain-resistant nylon-viscose fabric. Background Art

[0002] Nylon-viscose fabric generally refers to a fabric made of nylon layer and viscose fiber layer pressed together. This fabric combines the advantages of both fibers, with both the wrinkle resistance and fastness of nylon and the comfort and beauty of viscose fiber. Therefore, nylon-viscose fabric is often used in high-end furniture and car interiors, making the products more refined and attractive.

[0003] In addition, in order to ensure the stain resistance of nylon-viscose fabrics, nylon layers are usually selected as the outer surface layers of nylon-viscose fabrics, so that the dirt is difficult to adhere to the nylon-viscose fabrics due to the smooth characteristics of nylon fibers, which makes it convenient for users to clean the nylon-viscose fabrics during use. However, since the nylon layer is made of nylon fibers interwoven, such as a nylon-viscose fabric disclosed in Chinese utility model patent: CN218893813U, the fiber interwoven structure of the nylon-viscose fabric can easily form tiny depressions on the surface of the nylon layer, causing users to easily brush pollutants into the depressions during cleaning, so that the pollutants remain on the nylon-viscose fabrics, polluting the nylon-viscose fabrics and affecting the aesthetics of the nylon-viscose fabrics.

[0011] Furthermore, the lifting seat is provided with a sliding groove for sliding connection with the limiting seat, the sliding groove is provided with a sliding rail, and the limiting seat is slidingly connected with the sliding rail.

[0012] Furthermore, a trowel plate is provided between the drying mechanism and the spraying mechanism, and the trowel plate is tiltedly arranged on the conveying path. The conveying frame has a second lifting structure for controlling the lifting of the trowel plate, and the second lifting structure is the same as the first lifting structure.

[0013] Another object of the present invention is to provide a processing technology for stain-resistant nylon-viscose fabrics, including the stain-resistant nylon-viscose fabric processing equipment as described in any one of claims 1-9, characterized in that it includes the following steps: S1: preparing a hydrophobic agent, woven nylon fabrics, and adhesive fabrics; S2: ironing the nylon fabrics through the ironing rollers in each ironing structure to obtain a nylon fabric with a smooth surface; S3: air-drying the ironed nylon fabrics through a plurality of fans in the air-drying mechanism to obtain a nylon fabric with a stable surface; S4: coating the air-dried nylon fabrics through a plurality of atomizing nozzles in the spraying mechanism to obtain a nylon fabric with a hydrophobic layer on the surface; S5: drying the nylon fabrics through the drying mechanism to solidify the hydrophobic layer on the nylon surface; S6: pressing the dried nylon fabrics and the adhesive fabrics to obtain nylon-viscose fabrics.

[0014] The working principle and beneficial effects of the present invention are:

[0015] 1. The fabric conveying device of the present invention is provided with an air-drying mechanism, a spraying mechanism, a drying mechanism, and a plurality of ironing structures in sequence. Each ironing structure is close to the entrance of the fabric conveying device, so that each nylon fabric conveyed by the fabric conveying device will first be subjected to the ironing effect of each ironing structure. With the help of the heat and pressure generated by the ironing structure during ironing, the surface of the nylon fabric becomes flat, thereby avoiding the presence of multiple depressions on the surface of the nylon fabric, preventing stains from remaining on the surface of the fabric with the help of these depressions, and improving the stain resistance of the fabric; each ironing structure is arranged in sequence along the conveying direction of the fabric conveying device, ensuring that the fabric can pass through each ironing structure in sequence when being conveyed by the fabric conveying device, so that each ironing structure can iron the fabric in sequence, and ensure the ironing effect.

[0016] 2. The air-drying mechanism in the present invention is located between each ironing structure and the spraying mechanism, that is, the fabric after ironing will be air-dried before spraying, ensuring that the surface of the fabric can be in a dry state when the spraying mechanism sprays the hydrophobic layer on the fabric, so that the hydrophobic agent sprayed by the spraying mechanism can better adhere to the surface of the fabric, thereby ensuring the durability of the hydrophobic layer. The hydrophobic layer prevents liquid and dirt from penetrating into the interior of the fabric, making it difficult for stains and dirt to firmly adhere to the surface of the fabric, thereby improving the stain resistance of the fabric. The spraying mechanism is located between the air-drying mechanism and the drying mechanism, that is, the sprayed fabric will enter the drying mechanism, so that the hydrophobic layer can be quickly solidified on the surface of the fabric, to ensure that the hydrophobic layer can firmly adhere to the surface of the fabric, and improve the durability and stability of the hydrophobic layer.

[0017] 3. Each ironing structure in the present invention includes a mounting frame, an ironing roller, and an auxiliary roller. The mounting frame is arranged on the fabric conveying device, and the ironing roller is rotatably connected to the mounting frame. That is, the ironing work in the present invention is performed by the ironing roller. Compared with the traditional iron, which needs to control the iron to move back and forth on the fabric, the ironing roller only needs to roll along the fabric, and the ironing roller can cover a larger area at one time, ensuring the ironing efficiency of the fabric; the auxiliary roller is on a straight line with the central axis of the ironing roller, and the conveying path of the fabric conveying device is located between the ironing roller and the auxiliary roller, so that the fabric is ironed by passing through the gap between the ironing roller and the auxiliary roller. The auxiliary roller can effectively prevent the fabric from sinking due to the force of the ironing roller, ensuring that the ironing effect of the ironing roller can fully act on the fabric, thereby ensuring the ironing effect of the ironing roller.

[0018] 4. The fabric conveying device in the present invention is provided with a plurality of first lifting structures for controlling the lifting and lowering of each mounting frame. Through the lifting action of the first lifting structure, the distance between the ironing roller and the fabric conveying device can be effectively changed, so that the present invention can act on fabrics of different thicknesses, thereby expanding the scope of use of the present invention and ensuring the practicality of the present invention.

[0031] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1

[0033] like Figure 1 to Figure 3 As shown, this embodiment proposes a stain-resistant brocade-viscosity fabric processing equipment, which mainly includes a fabric conveying device 1, and the fabric conveying device 1 includes a conveying path 11 and a conveying frame 12. The conveying path 11 in this embodiment is preferably a belt conveying structure mainly composed of a conveying belt and a plurality of conveying rollers, because the belt conveying structure can realize large-scale and long-distance transportation, can work continuously and stably, and improve production efficiency. Compared with other conveying equipment, they can usually handle a larger material flow rate; the conveying frame 12 is symmetrically and evenly distributed with the conveying path 11 as the center, so that there are supporting points on both sides of the conveying path 11 on the conveying frame 12 to ensure the stability of the operation of the fabric conveying device 1.

[0034] The conveying frame 12 is provided with an air-drying mechanism 2, a spraying mechanism 3, a drying mechanism 4, and a plurality of ironing structures 5. Each ironing structure 5 is located at the starting position of the conveying path 11 and is arranged in sequence along the conveying direction of the conveying path 11, so that the nylon fabric conveyed through the conveying path 11 can pass through each ironing structure 5 in sequence, and the heat and pressure generated by the ironing action of each ironing structure 5 are used to break the old bonds inside the fiber molecules in the nylon fabric, thereby increasing the deformation capacity of the fiber. When the fabric is cooled after being pressed, a balance is established at a new position and new chemical bonds are formed, thus fixing the shape, thereby making the surface of the nylon fabric (nylon layer) flat, eliminating the multiple depressions originally existing on the surface of the nylon fabric, thereby preventing stains from remaining on the surface of the fabric with the help of these depressions, and improving the stain resistance of the fabric.

[0035] At the same time, each ironing structure 5 is independent of each other, so that the staff can adjust the ironing temperature of the ironing structure 5 in sequence, thereby gradually increasing the ironing temperature of each ironing structure 5. Compared with insufficient temperature or frequent temperature adjustment, gradually increasing the temperature can complete the entire ironing process faster, thereby saving time and reducing costs, especially in mass production.

[0036] Each ironing structure 5 includes a mounting frame 51, an ironing roller 52, and an auxiliary roller 53. The ironing roller 52 is rotatably connected to the mounting frame 51, and the mounting frame 51 is arranged on the conveying frame 12, that is, the ironing work of the ironing structure 5 in this embodiment is mainly completed by the ironing roller 52. Compared with the traditional ironing, which requires the iron to move back and forth on the fabric, the ironing roller 52 only needs to roll along the fabric. When the fabric passes through the ironing roller 52 on the conveying path 11, it can also drive the ironing roller 52 to rotate by itself due to the contact with the radial surface of the ironing roller 52. In this embodiment, only when the conveying force of the fabric cannot drive the ironing roller 52 to rotate, the motor and other rotating driving parts located in the mounting frame 51 need to be started to control the ironing roller 52 to rotate, which effectively reduces the energy consumption of this embodiment; and the ironing roller 52 can cover a larger area at one time, and preferably the axial length of the ironing roller 52 is just equal to the conveying width of the conveying path 11, so as to avoid the ironing dead angle in this embodiment and ensure the ironing efficiency of the fabric.

[0037] The auxiliary roller 53 is rotatably connected to the conveying frame 12, and the conveying path 11 is located between the auxiliary roller 53 and the ironing roller 52. The auxiliary roller 53 and the central axis of the ironing roller 52 are on a straight line, so that when the ironing roller 52 irons the nylon fabric, the auxiliary roller 53 can support the conveying belt and the fabric, preventing the fabric from sinking due to the ironing force of the ironing roller 52, causing the fabric to escape from the ironing range of the ironing roller 52, thereby ensuring that the ironing effect of the ironing roller 52 can fully act on the fabric.

[0038] The conveying frame 12 is provided with a plurality of first lifting structures 6 for controlling the lifting and lowering of each mounting frame 51. With the help of the lifting and lowering action of the first lifting structure 6, the distance between the ironing roller 52 and the conveying path 11 can be effectively changed, so that the present embodiment can adapt to fabrics of different thicknesses, thereby increasing the convenience of use of the present embodiment and ensuring the practicality of the present embodiment.

[0039] like Figure 4 , Figure 8As shown, each first lifting structure 6 in this embodiment includes a lifting screw 61, a lifting seat 62, and a limit assembly 63 for limiting the rotation of the lifting screw 61. The mounting frame 51 is slidably connected to the lifting seat 62 and is transmission-connected to the lifting screw 61. The lifting screw 61 is rotationally connected to the conveying frame 12. That is, the first lifting structure 6 in this embodiment adopts a screw structure for lifting, because the screw lifting structure can usually withstand a large vertical load, and the screw transmission can provide precise position control and motion accuracy, so that the ironing roller 52 can stay at a required height or position. The limit assembly 63 can give a certain restraining force to the lifting screw 61, and the self-locking performance of the lifting screw 61 itself can fully prevent the ironing roller 52 from being displaced during ironing, which affects the normal ironing work of the ironing roller 52.

[0040] A plurality of lifting motors 64 are provided inside the conveying frame 12 for driving the lifting screws 61 to rotate. The lifting motors 64 correspond to the lifting screws 61 one by one and are fixed inside the conveying frame 12. The lifting screws 61 are linked to the output shafts of the lifting motors 64. That is, the rotational movements of the lifting screws 61 are independent of each other, so that the spacing between the ironing rollers 52 and the conveying path 11 can be adjusted separately, so that the redundant ironing rollers 52 can be raised while ensuring the ironing effect, so as to avoid damage to the fabric due to multiple ironing. While ensuring the safety of the fabric during processing in this embodiment, a redundant design of the ironing structure 5 is also made.

[0041] The lifting motor 64 in this embodiment is preferably a servo motor or other motor with precise control and positioning capabilities, so as to ensure the accuracy of the position of each ironing roller 52.

[0042] If necessary, a manual rocker can be provided on the lifting screw rod 61, so that when the lifting motor 64 is damaged, the staff can adjust the distance between the ironing roller 52 and the conveying path 11 by manual adjustment, thereby ensuring the practicality of this embodiment.

[0043] like Figure 5 to Figure 7As shown, the limiting assembly 63 in this embodiment includes a limiting member 631 and a limiting seat 632. The limiting seat 632 is slidably connected to the lifting seat 62. The lifting seat 62 is provided with a hydraulic cylinder 633 for controlling the sliding of the limiting seat 632, that is, the piston rod of the hydraulic cylinder 633 is fixedly connected to the end of the lifting seat 62 away from the lifting screw 61, so that the limiting seat 632 can move back and forth on the lifting seat 62 as the hydraulic oil inside the hydraulic cylinder 633 is injected; the limiting member 631 is flipped and set on the limiting seat 632, and the end of the limiting assembly 63 close to the lifting screw 61 is provided with a limiting clamping hole 611, and the limiting member 631 abuts against the hole wall of the limiting clamping hole 611, that is, when the limiting seat 632 moves to the specified position under the action of the hydraulic cylinder 633 After that, the limiting member 631 can be flipped to embed the limiting member 631 in the limiting clamping hole 611, and then the hydraulic cylinder 633 can be controlled to drive the limiting member 631 to move in the direction away from the lifting screw rod 61 by controlling the injection of hydraulic oil inside the hydraulic cylinder 633, so that the limiting member 631 is in contact with the hole wall of the limiting clamping hole 611, giving a certain pulling force to the lifting screw rod 61, and cooperating with the hole axis of the lifting screw rod 61 and the conveying frame 12 for rotation, so as to achieve a clamping effect on the lifting screw rod 61 to a certain extent, and restrict the lifting screw rod 61 to prevent the lifting screw rod 61 from rotating due to accidental rotation during the operation of this embodiment, resulting in a change in the gap between the ironing roller 52 and the conveying path 11, which affects the working stability of this embodiment.

[0044] A fixing member 634 for fixing the limiting member 631 is provided between the limiting member 631 and the limiting seat 632. With the help of the fixing member 634, the limiting member 631 always maintains a working state of abutting against the limiting hole 611, thereby preventing the limiting member 631 from falling out of the limiting hole 611 due to force, thereby ensuring the limiting stability of the limiting assembly 63 in this embodiment.

[0045] At the same time, the projection surface of the limit card hole 611 in the horizontal plane in this embodiment should be a circular structure, which is convenient for the limit member 631 to be embedded in the limit card hole 611, and can also avoid the limit member 631 being unable to effectively abut against the hole wall of the limit card hole 611 due to the rotation of the lifting screw rod 61. That is, no matter how much the lifting screw rod 61 rotates, the limit member 631 can generate an effective abutment relationship with the hole wall of the limit card hole 611, fully ensuring the practicality of the limit component 63 in this embodiment.

[0046] like Fig. 9As shown, the limiting member 631 in this embodiment has a connecting hole 6311, the limiting seat 632 has a fixing hole 6321, and the fixing member 634 is threadedly connected to the fixing hole 6321 and the connecting hole 6311, that is, the fixing member 634 in this embodiment fixes the limiting member 631 and the limiting seat 632 in a threaded manner, which not only ensures the strength and reliability of the fixed connection between the two, but also facilitates the subsequent disassembly and assembly of the fixing member 634. The fixing member 634 in this embodiment is preferably a common threaded fastener on the market such as a bolt, so that when the fixing member 634 in this embodiment is lost, a replacement can be quickly found.

[0047] The limiting member 631 includes an abutment body 6312 and a connecting rod 6313. The connecting rod 6313 is rotatably connected to the limiting seat 632. The abutment body 6312 abuts against the limiting clamping hole 611. The connecting rod 6313 and the abutment body 6312 are integrally formed. Specifically, the projection surface of the limiting member 631 on the vertical horizontal plane is an "L"-shaped structure. With the structural structure of the "L"-shaped structure, it is convenient to embed the abutment body 6312 into the limiting clamping hole 611 by flipping the connecting rod 6313, so that the limiting member 631 plays a limiting role on the lifting screw rod 61; the hole wall of the limiting clamping hole 611 and the end of the abutment body 6312 close to the limiting seat 632 both have an anti-slip layer 7. That is, the hole wall of the limit card hole 611 and the end of the abutment body 6312 close to the limit seat 632 are both frosted to make the surface of the abutment body 6312 and the surface of the limit card hole 611 rough, increase the friction between the two, and thus improve the limiting effect of the limit member 631; a reinforcing rib 6314 is provided between the connecting rod 6313 and the abutment body 6312, and the projection surface of the reinforcing rib 6314 on the vertical horizontal plane is a triangular structure, so that a firm triangular structure is provided between the connecting rod 6313 and the abutment body 6312, thereby preventing the limit member 631 from being deformed due to excessive force, resulting in the limit member 631 being unable to limit the lifting screw rod 61.

[0048] like Figure 2 , Figure 6 , Fig. 9 As shown, the lifting seat 62 in this embodiment has a slide groove 621 for the limit seat 632 to be slidably connected, and the slide groove 621 has a slide rail 622. The limit seat 632 is slidably connected with the slide rail 622, and the limit seat 632 has a matching groove that cooperates with the slide rail 622. With the cooperation between the slide rail 622 and the matching groove, a certain constraint is applied to the limit seat 632 to prevent the limit seat 632 from being displaced in other directions when being pushed by the hydraulic cylinder 633, so that the limit seat 632 can move to the specified position more stably, so that the limit member 631 can be embedded in the limit clamping hole 611. .

[0049] like Figure 1 to Figure 3As shown, the air-drying mechanism 2 in this embodiment is located between each ironing structure 5 and the spraying mechanism 3, that is, the nylon fabric after ironing will first be air-dried by the air-drying mechanism 2 before being sprayed. The air-drying mechanism 2 in this embodiment preferably includes a main frame and a plurality of fans. There is a passage for the fabric to pass through between the main frame and the conveying frame 12, and the air outlets of each fan are located in the passage. With the help of the airflow generated by each fan when working, the surface of the fabric after passing through each ironing structure 5 is cooled, thereby ensuring that the surface of the fabric can be in a dry state when the spraying mechanism 3 sprays the hydrophobic layer on the fabric, so that the hydrophobic agent sprayed by the spraying mechanism 3 can better adhere to the surface of the fabric, thereby ensuring the durability of the hydrophobic layer.

[0050] The spraying mechanism 3 in this embodiment preferably includes a support frame, a liquid storage tank, and a plurality of atomizing nozzles, each of which is connected to the liquid storage tank. The liquid storage tank is equipped with a water pump for providing a hydrophobic agent to each atomizing nozzle. There is also a channel for the fabric to pass through between the support frame and the conveying frame 12. Each atomizing nozzle is fixed on the support frame, and the water outlet of each atomizing nozzle is located above the conveying channel 11, so that each atomizing nozzle sprays the hydrophobic agent on the nylon fabric conveyed through the conveying channel 11, so that a hydrophobic layer is formed on the fabric, and the hydrophobic layer is used to prevent liquid and dirt from penetrating into the interior of the fabric, so that stains and dirt are difficult to firmly adhere to the surface of the fabric, thereby improving the fabric's pollution resistance. At the same time, during the spraying process of the spraying mechanism 3, the sprayed hydrophobic agent can fill the possible depressions that have not been ironed flat by the ironing structure 5, that is, the hydrophobic layer formed by the hydrophobic agent can further make the surface of the nylon fabric (nylon layer) flat, thereby ensuring the fabric's pollution resistance. In addition, a plurality of splash shields should be provided on the conveying frame 12 , and each splash shield plays a role in shielding water mist to prevent the water mist of the hydrophobic agent sprayed by the atomizing nozzle from floating out from the left and right sides of the conveying frame 12 .

[0051] The spraying mechanism 3 is located between the drying mechanism 4 and the air-drying mechanism 2, that is, the sprayed fabric will enter the drying mechanism 4. The drying mechanism 4 in this embodiment is preferably a drying furnace or other drying equipment dedicated to the fabric conveying line, so that the hydrophobic layer can be quickly solidified on the fabric surface to ensure that the hydrophobic layer can be firmly attached to the fabric surface, thereby improving the durability and stability of the hydrophobic layer.

[0052] At the same time, a trowel plate 8 is provided between the drying mechanism 4 and the spraying mechanism 3, and there is a certain gap between the trowel plate 8 and the conveying path 11 for the normal passage of the fabric, and the existence of the trowel plate 8 will block the excess hydrophobic agent on the fabric from entering the drying mechanism 4 as the fabric continues to move forward, thereby controlling the thickness of the hydrophobic layer on the surface of the fabric and ensuring the consistency and uniformity of the hydrophobic layer on the fabric. Preferably, the trowel plate 8 is tilted on the conveying path 11, and compared with the vertically arranged trowel plate 8, the tilted setting helps the operator to maintain the balance of force during the smoothing process. The correct tilt angle can help the construction worker apply appropriate pressure to the trowel plate 8 to ensure that the hydrophobic coating is evenly smoothed.

[0053] The conveyor frame 12 is provided with a second lifting structure 9 for controlling the lifting of the trowel plate 8. Both sides of the trowel plate 8 should be provided with connecting parts for cooperating with the second lifting structure 9. The second lifting structure 9 has the same structure as the first lifting structure 6, that is, the trowel plate 8 can also adjust its height position to cooperate with fabrics of different thicknesses for smoothing work.

[0054] Example 2

[0055] Based on the equipment provided in Example 1, this embodiment proposes a processing technology for stain-resistant nylon-viscose fabrics, which mainly includes the following steps:

[0056] S1: Prepare the hydrophobic agent, woven nylon fabric, and adhesive fabric, complete the preparation of nylon-adhesive fabric, and ensure the smoothness of processing.

[0057] S2: ironing the nylon fabric by the ironing rollers 52 in each ironing structure 5, that is, after placing the nylon fabric on the conveying path 11, the nylon fabric is passed through each ironing structure 5 in sequence, and the nylon fabric is ironed by the ironing rollers 52 in each ironing structure 5, that is, by means of the ironing effect of each ironing structure 5, multiple depressions originally existing on the surface of the nylon fabric are eliminated, so as to obtain a nylon fabric with a smooth surface, thereby preventing stains from remaining on the surface of the fabric by means of these depressions, and improving the stain resistance of the fabric;

[0058] S3: The ironed nylon fabric is sent to the air-drying mechanism 2 through the conveying path 11, and the ironed nylon fabric is dried by a plurality of fans in the air-drying mechanism 2, that is, the surface of the fabric after passing through the ironing structures 5 is cooled and dried by the airflow generated by the fans in the air-drying mechanism 2, so as to obtain a nylon fabric with a stable surface, so as to facilitate the subsequent spraying of the nylon fabric;

[0059] S4: The air-dried nylon fabric is sent to the spraying mechanism 3 through the conveying channel 11, and the surface of the nylon fabric is sprayed by a plurality of atomizing nozzles in the spraying mechanism 3, that is, the hydrophobic agent is sprayed on the nylon fabric conveyed through the conveying channel 11 by each atomizing nozzle in the spraying mechanism 3, so that a hydrophobic layer is formed on the fabric, and the hydrophobic layer is used to prevent liquid and dirt from penetrating into the interior of the fabric, so that stains and dirt are difficult to firmly adhere to the surface of the fabric, thereby improving the stain resistance of the fabric;

[0060] S5: The sprayed nylon fabric is sent to the drying mechanism 4 through the conveying path 11, and the nylon fabric is dried by the drying mechanism 4, so that the hydrophobic layer on the surface of the nylon fabric can be quickly solidified on the surface of the fabric, so as to ensure that the hydrophobic layer can be firmly attached to the surface of the fabric, even if the hydrophobic layer is solidified on the nylon fabric, the durability and stability of the hydrophobic layer are improved, and the preparation of the nylon fabric is completed; and before the nylon fabric is sent to the drying mechanism 4 through the conveying path 11, the hydrophobic coating on the surface of the nylon fabric is smoothed by the screed plate 8, so as to ensure the consistency of the hydrophobic coating on the surface of the nylon fabric;

[0061] S6: The dried nylon fabrics are collected and transported to a pressing mechanism, where they are pressed together with adhesive fabrics into nylon-adhesive fabrics to obtain nylon-adhesive fabrics, thereby completing the processing of the nylon-adhesive fabrics. Both sides of the adhesive fabrics are nylon fabrics, thereby ensuring that the nylon-adhesive fabrics pressed together by the nylon fabrics and the adhesive fabrics have double-sided stain-resistant properties. At the same time, the pressing mechanism in this embodiment is preferably a bonding machine or the like that uses hot melt adhesive for bonding without destroying the fabric structure, thereby ensuring the integrity of the nylon-adhesive fabrics.

[0062] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
