DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, a description will be given of a heat source for piping material.

The heat source material for piping material according to the present embodiment is composed of a heat insulating material 10, a heat supply means 20, an inner skin 30, a sheath 40 and a removable member 50.

The heat insulating material 10 is for warming, and may be composed of silica fibers or aramid felt.

The heat supply unit 20 includes a heat wire 21 and a lead wire 22. The hot wire 21 is fixed by sewing because the position of the hot wire 21 is fixed. In this embodiment, the hot wire 21 is fixed to the heat insulating material 10 as shown in FIG. Of course, the heating wire 21 may be fixed to a separate cloth and the cloth may be fixed to the heat insulating material 10.

As shown in FIG. 1, the inner film 30 and the outer film 40 surround the heat insulating material 10 and the heat supplying means 20 as a whole, and the inner film 30 has a portion And the outer covering 40 is located on the opposite side to the inner skin and is exposed to the outside.

The inner skin 30 and the outer skin 40 are composed of at least one sheet selected from nonwoven fabric coated with Teflon having a thickness of 2.0 mm or less, carbon fiber, aramid fiber, silica fiber, glass fiber, or E-PTFE fiber And an outer skin.

Teflon-containing materials are highly heat- and chemical-resistant, and can be used in a wide range of temperatures. However, in the case of weaving in the form of a fabric, there is a possibility that fibers such as aramid, silica, glass, carbon and the like used as an insulating material due to fine holes are discharged to the outside in the form of fine dust. However, in the case of the sheet used in the present invention, by performing Teflon coating on the fabric composed of the nonwoven fabric, carbon fiber, aramid, silica and glass fiber, the oxidation resistance and workability of the fabric itself by the coating are excellent, It is possible to suppress the deformation caused by the vibration. In addition, the e-PTFE sheet is produced by rapidly expanding the PTFE material. It has all the advantages of the PTFE material and is not woven, so there is no room for the inner material to be discharged to the outside, A thickness of about 1.5 mm), it contains a fine air layer in the inside thereof, and thus it has a very good merit.

The attachment / detachment member 50 is used for temporarily fixing the heat source material for piping material to the piping material or separating it from the piping material. In this embodiment, the ring 51, the hook 52, A hook 53, and a lid.

The ring 51 is made of PTFE material and is elastically deformable. The hook 52 and the hook 53 are used for everyday use and are made of stainless steel.

The hooks exposed to the outside form a cover to prevent the hooks and the hooks from being broken from the outside.

The ring 51 is elastically deformed so that when the hook 52 is hooked on the hook 53 in a state where the ring 51 is elastically deformed, the fastening state of the hook 51 is maintained very firmly by the elastic restoring force of the ring 51.

In the past, most of the cases of using the Velcro as the attaching and detaching member, the case of the Velcro may cause the fine dust to be blown in the process of desorption, and in the case of the workplace where fine dust is strictly controlled like the semiconductor process, However, it can be configured in such a manner that any one or more methods selected from a hook system, a belt system, a ring system, a button system, and a Bechro system can be combined according to different usage environments.

Hereinafter, a method of manufacturing a heat source fabric for piping according to another embodiment of the present invention will be described.

A method of manufacturing a heating material for piping material according to the present embodiment is a method of manufacturing a heating cover for piping material including a heat supply means including an inner pipe, an outer pipe, a heat insulating material and a hot wire. A step of joining the heat supply means, a step of joining the inner and outer jackets, and a step of forming the releasable member.

The inner / outer jacket preparation step may be performed by the inner / outer jacket forming step of forming the inner / outer jacket, which is composed of the fabric (at least one selected from a nonwoven fabric coated with Teflon, carbon fiber, aramid fiber, silica fiber, glass fiber, or E-PTFE fiber) / It is a step to prepare by cutting based on actual data of the drawing or piping. The advantages of using the fabric as the material of the inner skin and the sheath are sufficiently described in the description of the embodiment of the heating material for piping material, and thus the detailed description thereof will be omitted. Generally, drawings of the piping materials and the actual piping materials are made in the same way, but there may be differences, so if necessary, the piping materials are measured and cut according to the shape.

The step of preparing the heat insulating material is a step of preparing the heat insulating material by cutting based on actual data of the drawing or piping.

The step of joining the heat supply means is a step of joining the heat supply means (including the heat wire and the lead wire) to the heat insulating material. As shown in FIG. 1, the heat supply unit may be directly coupled to the heat insulating material, or the heat supply unit may be coupled to a separate cloth, and then the cloth may be combined with the heat insulating material again.

The inner / outer skin bonding step is a step of bonding the inner skin and the outer skin in a state where the thermal insulation material and the heat supply means are accommodated between the inner skin and the outer skin.

The inner / outer sheathing step is performed by sewing or stitching (sewing) the sewed or touched thread toward the heat insulating material and the heat generating means without being exposed to the outside. This is preferably accomplished by a combination of sewing and stitching. Since the sewing speed is much faster than the sewing, it is mainly sewing, but the required part is by sewing.

For example, assuming that a rectangular heating heater cover as shown in Fig. 1 is made, the three sides of the rectangle are joined together by sewing. When the three sides are combined, the sewing thread is turned over to face the side where the heat insulating material and the heat supply means are accommodated, and then the other side is worked by cauterization. In this case, the semi- .

3 is a photograph of an example of a heat-insulating heating cover for piping material manufactured in this manner. As you can see in the photo, no thread is exposed on the outside.

The heat source for piping material is a material having excellent characteristics as described above. However, the needle is punctured during the stitching or sewing process. Through the hole formed at this time, fine particles such as heat insulating material inside the room are discharged to the outside Therefore, in order to prevent this, the seal is not exposed to the outside. In addition, sealing work can additionally be performed with a tape having a Teflon material.

At this time, the presser foot used for sewing should be a flat bottom surface. The presser foot moves up and down together with the needle when sewing, and the sewing object is temporarily fixed in a downward position. At this time, the presser foot moves not only in the vertical direction but also in the forward and backward directions on the basis of the worker. The movement of the presser foot moves the object of sewing (hereinafter referred to as the "object to be cut") away from the worker. A groove is formed in the bottom of the presser foot to facilitate the movement of the object. When the groove is formed, the frictional force becomes large, which is advantageous for moving the object seal.

4 shows a comparison between a conventional presser foot and a presser foot used in the present invention. The presser foot shown in FIG. 4 is a conventional presser foot 72, and the presser foot shown in the upper side is a presser foot 71 used in the present invention. It can be seen that the bottom surface of the presser foot has no groove and is flat.

It has already been described that the e-PTFE sheet among the fabrics for piping materials is a very excellent material to be used as the inner / outer shell of the heat-generating fabric for piping material. Therefore, in order to compensate for the disadvantage that the scraping easily occurs, the presser foot 71 having a flat bottom is used, and a sealing operation may be further performed using Teflon tape at the bar portion.

5 is a photograph showing a state in which a conventional presser foot is sewn and a flat presser foot 71 is compared. The configuration indicated at 60 in FIG. 5 is a thread. These chambers are arranged toward the insulation as described above and are not exposed to the outside. 5 is a cutter formed by the conventional presser foot 72. In FIG. The performance of the exothermic fabric is not deteriorated by such a cutter, but it is desirable to minimize such cutter. Therefore, the presser foot 71 having a flat bottom is used, and the cutter shown in FIG. 5 is not produced at all.

The attaching / detaching member forming step is a step of forming a detachable member 50 on the outer skin 40. At this time, the attaching / detaching member 50 is constituted by the ring 51, the hook 52 and the latching ring 53, and the lid, which has been described in the above description of the heat source for the piping material, .

As a method for forming the removable member 50, a sewing material may be used.

When the attaching / detaching member 50 is formed, the manufacturing method of the heat generating fabric for piping according to the present invention is completed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, Various types of heating fabrics for piping materials and fabrication methods thereof.
