Digital garments are expected to be used to connect and exchange information in real time in the ubiquitous era and to realize a human-centered environment.

The core part of digital company is composed of highly conductive metal filament such as copper, brass, silver, and gold. It is coated with resin for insulation and electromagnetic shielding and has a diameter of 50 ~ 200μm.

If the density of the yarn used in the covering to cover the resin-coated outer portion is low, slip occurs at regular intervals because the yarn is pushed out by mechanical friction and separated from the core. Because the friction is high, the resin is peeled off, the metal filament is exposed to the outside, the insulation effect is decreased, and the digital thread can be cut off. Therefore, the digital yarn must be made to adhere to the core effectively.

When covering the core part of digital company, if the covering seal density is high, the digital company presses the coated resin of core part hard and penetrates the resin, which leads to metal filament and deteriorates the insulation effect. Through this covering part, it is drawn out in a loop, and in the subsequent process, the thread of the digital yarn is cut off due to mechanical friction, which reduces productivity.

Therefore, in order to mass produce digital garments using digital yarns, the core part of the digital yarns uses various colors and materials to improve mechanical touch and aesthetics in order to minimize mechanical frictional force in subsequent processes. There is an urgent need to develop a digital covering technology that improves productivity.

The present invention is to provide a manufacturing method capable of covering the core portion of the digital yarn having a diameter of 50 ~ 200μm with a general thread.

In addition, the present invention is to provide a manufacturing method that can be controlled by adjusting the density to cover the core portion of the digital yarn with a common yarn without slip phenomenon.

In addition, the present invention is to provide a manufacturing method that can cover the core portion with a common pressure at a constant pressure to prevent the core portion of the digital yarn is severely pressed by the general yarn to lower the insulation phenomenon.

In addition, the present invention is to provide a covering technology of the digital company that can reduce the mechanical friction in the subsequent process that is added to the digital company to produce a digital garment, and minimize the threading breaks caught by the needle or parts of the machine.

In addition, the present invention is to provide a technology that the heat treatment for the digital company to improve the flexibility and friction force of the digital company after the covering process.

With reference to the accompanying drawings, a manufacturing method and a manufacturing apparatus for a covering of a digital company according to the present invention for achieving the above object are as follows.

1 is a block diagram schematically showing a manufacturing method of a digital company according to the present invention;

First step: supplying the core portion of the digital company;

Second step: automatically aligning the core portion of the digital yarn to the center;

Third step: covering the outside of the core portion with a normal thread;

Fourth step: heat-treating the covering portion of the digital yarn;

Step 5: winding the digital yarn;

Characterized in that comprises a.

Hereinafter, a method of covering the digital yarn with a general thread will be described in detail with reference to FIGS. 2 and 3, which show an enlarged overall configuration and main part of the covering manufacturing apparatus of the digital yarn.

The first step is a step in which the core portion of the digital yarn is constantly supplied.

The core portion 5 supplied here is coated with an insulating resin of 2 to 30 twisted metal filaments. The diameter of one strand of the metal filament is 1 to 20 μm, and 5 to 12 μm is preferably used. Size can also be used

In the case of using the metal filament, the diameter of the core portion including the portion coated with the insulating resin is 50 ~ 200μm, but is not limited thereto.

In addition, since the metal filament constituting the core part has no elasticity at all, it is easy to cause broken yarn broken by slight tension, so it is sensitive to minute tension in the process of feeding the core part to prevent this. You need a sensing device that can move in response.

The core portion is unwound from the core bobbin (1) wound to a predetermined length and is supplied between a pair of feed rollers (2) made of elastic rubber or polyurethane material, and the feed roller (2) is connected to the core portion (5). Detect the diameter and rotate while pressing the core part (5) at a constant pressure to supply to the next step.

At this time, the micro spring 3 and the pressure measuring device 4 for detecting the pressure are attached to one end of the supply roller 2 so that the pressure is varied according to the diameter of the core part 5 to closely contact the roller.

The pressure for pressing the core portion 5 of the digital yarn is 20 to 1,500 cN depending on the diameter of the core portion, but is not limited thereto.

The second step is to make the core portion of the digital yarn in the center of the entire carrier tracker 9 before covering.

This is because the diameter of the core part 5 is very small, so if it is not centered and pushed to one side, the covering is not made properly, and the core part 5 is drawn out of the covering part of the digital yarn and comes out in a loop form. Since the nozzle 6 may be formed at the center of the carrier device by installing a tapered cylindrical shape having an outlet diameter smaller than the inlet diameter, the core portion 5 may be formed through the nozzle 6. It is fed to the next stage, passing through the nozzle 6 at a speed of 1-100 m / hr.

Since the core portion 5 is made of resin, the resin component may be peeled off or melted due to friction with the nozzle when passing through the nozzle 6 at a high speed, so that the resin component is reduced in order to reduce frictional force with the nozzle 6. Rather, the ceramic nozzle 6 is used, but when passing at low speed, both the resin and the ceramic nozzle can be used.

The third step is to cover the core portion with a constant density.

The covering device includes a core part 5 of a digital yarn in which a yarn to be covered is wound while the carrier 8 mounted on the carrier track device 9 having a concentric shape travels along the carrier track groove 10 having an '8' shape. ) To cover.

The number of carriers 8 used herein may vary depending on the type of yarn used for the covering and the density of the covering, but generally 2 to 20 carriers 8 are used.

In order to form the covering in the core part 5, a circular ring 11 is used, which makes the yarn wound around the yarn bobbin 7 so that the outside of the core part 5 can be woven into the outer shell. (11) is the yarn 15 wound around the yarn bobbin (7) moving by the carrier is gathered in the form of a conical shape from all sides to form an outer shell shape of the core portion (5).

The yarn used here is Nylon, Acrylic, Polyester, Polyethylene, Polypropylene, Viscose, Cellulose, Polyamide 6 ), Chemical fibers such as Polyamide 6.6, Aramid, Ultra high molecular weight polyethylene (UHMW PE), Carbon fiber, etc., Wool and cotton ( Natural fibers such as cotton may be used, but are not limited to these.

It is also possible to use both filament yarn and staple yarn in which the yarn is a constituent form. It is also possible to use undyed yarns with dyed yarns, regardless of whether they are dyed.

The fourth step is a step of heat-treating the cover portion of the digital yarn.

If the cover part surrounding the core part 5 of the digital company does not press the core part more than a certain pressure, and mechanical friction occurs, the mechanical part is pushed apart from the core part and the coating part of the core part is peeled off to expose the metal filament. Trimming may occur.

Therefore, the digital yarn passes the steam device 12 through which 100-200 ° C of high-temperature steam is injected for 1 to 30 seconds depending on the material used for the cover portion, and the yarn used for the cover portion contracts at a high temperature so that core It is made to squeeze the part, it is subjected to heat treatment (13) of the digital company in order to improve the flexibility of the yarn used in the resin and the cover part to reduce mechanical friction in the subsequent process.

The fifth step is a step of winding the digital yarn 14 after the heat treatment 13 is finished on the bobbin.
