The present invention has technical features in the method for producing the nonwoven fabric and the nonwoven fabric produced accordingly.

Conventional nonwoven fabrics are manufactured by dipping and drying, and the dipping method is to dry the heat treatment after soaking the fibers in a synthetic resin adhesive bucket, dry is a thin cotton of polyethylene or polypropylene in a carding machine (Carding machine) It is manufactured by spouting synthetic resin and applying heat to the processed product in the form of a web made in a shape.

As an example of manufacturing the nonwoven fabric, the present invention releases the above-described polymer material resin for nonwoven fabric through an extruder. In this case, in the case of manufacturing in the form of a general film, the nozzle of the extruder is in a straight form, and when the pressure is applied to the extruder, the polymer resin is extruded while forming a film in the form of a surface. And the film of the extruded surface form through the cooling process to produce a film form.

According to the present invention, the nozzle of the extruder forms a plurality of fine holes, and is extruded in the form of a yarn in the extruder through the fine holes. As the polymer resin is extruded in the form of a thread, it falls. The polymer resin in the form of dropped yarns uses a forced flow of air to weave tens of thousands of yarns onto the felt.

The yarns thus moved are moved to calendar rolls through the bolts, and the calendar rolls are pressed into a nonwoven fabric. In this case, the calendar roll may form a constant pattern when the yarns are pressed.

The method of producing the nonwoven fabric described above is one embodiment of the nonwoven fabric of the present invention. Accordingly, nonwoven fabrics produced by any other method using a polymer resin are also included in the present invention.

The present invention performs a step of forming a resin coating layer by applying a film coating on one side using a polyethylene or other polymer material resin using a laminating machine to the nonwoven fabric.

In this case, the resin coating layer may be a polymer material resin of polyethylene, polypropylene, polystyrene, polyester, which is a polymer material used for the manufacture of the nonwoven fabric, alone or in combination of two or more kinds thereof. It is preferable to use the polymer resin used in the manufacturing process of the adhesive tape.

After the coating layer is formed, a process of forming an adhesive layer by attaching the adhesive layer to the other surface of the nonwoven table layer using an adhesive is performed.

When the adhesive layer is attached to the adhesive using a conventional cotton cloth, such a adhesive layer has a space between the yarn and the yarn, so after filling the space with the adhesive, the adhesive layer needs to be formed to a certain thickness again, which requires a lot of adhesive. there was.

When the adhesive tape is manufactured using a conventional cotton cloth as shown in FIG. 2, the cotton cloth layer 40 has a space formed between the weft and the warp yarn of the cotton yarn, so that the resin of the adhesive or the coating layer takes much.

However, the present invention completely solves such a problem by using a nonwoven fabric, since the nonwoven fabric has a flat shape and thus no space portion such as the above-described cotton cloth is formed.

The adhesive used in the present invention may use an adhesive used in a conventional adhesive tape, preferably made of a rubber component or may include a rubber component.

As described above, the present invention provides an adhesive tape including three layers including a nonwoven layer.

In this way, the adhesive tape having three layers formed is wound on the paper pipe by a certain length, and the wound tape is cut and packaged to a width suitable for the user's use by using a cutter, thereby completing the adhesive tape visible on the market.

The technical feature of the present invention is that a hardened bed 11 is formed in which the cross section of the nonwoven fabric of the nonwoven fabric layer is formed at a constant interval and a predetermined width.

In the present invention, the spacing of the hard flower bed may be variously adopted according to the needs of the user, and when using a general adhesive tape, it is common to use an interval of 1 to 3 cm.

In the present invention, the hardening stage means that the nonwoven fabric is hardened at a predetermined interval and width in a cross section (cross direction) of the nonwoven fabric to make it hard, and the nonwoven fabric and other physical properties of other portions are formed differently.

As shown in FIG. 3, the hard flower bed may be in the form of a straight cross section of the nonwoven fabric or in the form of a broken date as shown in FIG. 4.

Therefore, the hardening stage of the present invention hardens a part of the nonwoven fabric used in the present invention when manufacturing the adhesive tape, so that the nonwoven fabric can be easily cut into the cross section by changing its physical properties. It is included.

As described above, the present invention can utilize the strong toughness of the nonwoven fabric, but when the adhesive tape is manufactured from the nonwoven fabric, the user can easily cut the portion of the nonwoven fabric by forming a hard flower bed as described above, without the user using any cutter. An effect that can be stolen is created.

The present invention can be carried out by a method of forming a hardening stage of the nonwoven fabric, which is the technical feature described above, by heat-treating the film at a predetermined interval on the cross section of the nonwoven fabric.

The non-woven fabric may be heat treated in various ways. In the present invention, calenderol may be used, but is not limited thereto.

As described above, the nonwoven fabric of the present invention is made of a polymer resin, and the polymer resin has a property of hardening when heat is applied. When the high-rich material resin is heated and cooled to a part forming the hardened bed as shown in FIG. 3 or 4, the hard hardened bed in the form of a film is formed.

The present invention will be described as an example of the method of forming a hard flower bed in the nonwoven fabric described above.

The nonwoven fabric produced as mentioned above prepares the nonwoven fabric wound up to the branch pipe.

The nonwoven fabric thus prepared is placed on a nonwoven unwinder and then transferred to the calendar roll as the line flows.

Calendar roll is composed of the upper calender roll 100 and the lower calender roll 200, as shown in the example of Figure 5, the action groove of the shape suitable for the hard end of the nonwoven fabric described above in either the upper calender roll or the lower calender roll 110 is formed.

The shape of the working groove may be employed in various ways, such as a straight (Iksan) form or broken form (一字) form in accordance with the above-mentioned rigid flower bed of the nonwoven fabric.

In addition, as shown in the example of Figure 6, the action groove is formed in the pressing means 120 to apply a constant pressure to the nonwoven fabric flowing into the calendar roll.

Such a pressurizing means moves both the working groove up and down, and means and an apparatus capable of applying pressure to the nonwoven fabric are all possible. Therefore, a hydraulic cylinder, an air cylinder, etc. can be installed and used as a pressurizing means.

In addition, the time point to press the pressing means can be pressed at the time of the nearest calendar calender roll to be close to each other, the means for making this action can be implemented by a conventional pressing means control system.

Other calendar rolls also consist of a common flat calendar roll.

In addition, the present invention is applied heat to the calendar calorie to a certain temperature. The constant temperature may be variously adopted depending on the physicochemical properties of the nonwoven fabric made of the polymer resin used in the present invention, and is applied at about 50 to 200 degrees C depending on the degree of curing thereof. However, the temperature range does not limit the content of the present invention and may be changed depending on the nonwoven fabric.

Means for applying heat to the calendar roll in the present invention can be achieved through conventional heat transfer means, for example, it is possible to heat the calendar roll by using a heat medium oil or an electric heater.

In this case, heat may be applied to the upper calendar roll and / or the lower calendar roll, and it is preferable to apply the heat to the flat calendar roll. As such, when heat is applied to the calendar roll, heat is applied to the nonwoven fabric passing through the calendar roll.

In the present invention, the heat is applied to the nonwoven fabric passing through the calendar roll to give a ductility, and the compression is performed by applying a pressure to the nonwoven fabric softened by the working groove of any calendar roll. The hardening phenomenon occurs.

In other words, the pressure applied to the action grooves causes the woven phenomenon of the thread of the nonwoven fabric to be cut off and a melting phenomenon occurs. As a result, a hard film bed of a hard film form is formed.

As another example of forming the hard flower bed in the present invention, the hard flower bed may be formed by performing an ultrasonic wave generator in a cross direction of the nonwoven fabric using an ultrasonic wave generating device or means 121.

As shown in FIG. 7, the ultrasonic non-woven fabric is mounted on the nonwoven unwinder device and then ultrasonic waves are used in the transverse direction of the nonwoven fabric while the ultrasonic generator is moved to the nonwoven winder device according to the flow of the line. By doing so, it is possible to form the hardened end in the transverse direction of the nonwoven fabric.

In addition, the present invention employs a method of forming a cutting line in the transverse direction of the nonwoven fabric instead of the method of forming a hard flower bed in the nonwoven fabric can be easily cut when using the adhesive tape.

As shown in FIG. 8, a device or means 122 may be used to form a cutting line while the produced nonwoven fabric is seated on a nonwoven unwinder apparatus and then moved to the nonwoven winder apparatus according to the flow of the line. To form a cutting line 12 in the form of a broken line at regular intervals in the transverse direction of the nonwoven fabric.

Therefore, the cutting line forming apparatus is equipped with a cutting device such as a blade or awl 122-1 at regular intervals in the roller-shaped body as shown in Figure 8 is to form a cutting line as the nonwoven fabric is moved.

In addition, the cutting line forming device may be formed by applying heat to the nonwoven fabric using a laser or the like instead of a blade or a perforator.

In addition, the present invention can be used in the above-described cutting line forming apparatus is a method of punching a circular, elliptical or the like on the nonwoven fabric to form the cutting holes 13 at regular intervals in the nonwoven fabric.

In this case, as shown in FIG. 9, the cutting hole forming apparatus 123 in which the punching machine 123-1 is formed at a predetermined interval in the roller-shaped body moves the nonwoven fabric so that the cutting hole is formed. Here, the perforator may be configured by physical means such as an awl, a punch, or the like, or heat generating means such as a laser.

The present invention forms a cutting line, a cutting hole, or a hard flower bed at regular intervals on the nonwoven fabric forming one layer of the adhesive tape so that the user can easily cut the adhesive tape when the adhesive tape is manufactured.

After the nonwoven fabric having the hardened stage is passed through the calenta roll process, the nonwoven fabric formed by the rewinder is wound again through the guide roll, and the nonwoven fabric having the hardened stage wound as described above is transferred to the above-described adhesive tape manufacturing process.

In this case, the nonwoven fabric is cooled in a natural cooling manner before the nonwoven fabric is wound on the rewinder.

The present invention can be used to produce an adhesive tape with a significantly increased strength using a nonwoven fabric, thereby providing an adhesive tape accordingly.
