Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a fabric having a sensor function, and more specifically, it can be provided with a function to instantly detect and notify adhesion of urine, etc., and can be used as a diaper cover. , bedwetting sheets,
This invention relates to a sensor fabric suitable for use in underwear, etc.

[Conventional technology]

When using diaper covers, bedwetting sheets, underwear, etc., if urination occurs, it is desirable that the user and those around him/her immediately detect it.

For this reason, in recent years, diaper covers, bed-wetting sheets, underwear, etc. have been fitted with color sensors that change color when detecting moisture, allowing them to detect how wet they are due to urination, etc., or printing patterns on them. , fabrics that create a contrast when wet due to the difference in moisture penetration between patterned areas and non-patterned areas can be used in diaper covers, bedwetting sheets, underwear, etc. to identify wetness, and even to detect wetness. Sensors that play a melody when this occurs are attached to diaper covers, bedwetting sheets, underwear, etc.

[Problem to be solved by the invention]

However, when color sensors are attached to diaper covers, bedwetting sheets, underwear, etc., or fabrics are printed with contrasting patterns, it is not possible to tell whether the diaper has gotten wet unless you look at the color sensor or the printed pattern. Also, even if you are wet, you cannot tell those around you. In addition, those equipped with a sensor that starts playing a melody have a small area that can perform the sensor function, so the sensing range is extremely small. This causes problems such as giving the user a feeling of discomfort or discomfort.

[Means to solve the problem]

The present invention was made as a result of intensive research to solve these problems, and involves embroidering a pair of conductive wires onto a fabric, and providing a sensor connection part at the terminal of the pair of conductive wires. A sensor fabric with a sensor function is used, and a sensor is attached to the sensor connection part to detect and notify the current flow between the conductive wires. If the wetness occurs, the sensor instantly detects the wetness and notifies the user of the wetness, so that the user and those in the vicinity can immediately detect the wetness.

〔Example〕

Hereinafter, an embodiment of the sensor fabric of the present invention will be described with reference to the drawings.

FIG. 1 shows a sensor fabric according to the present invention. This sensor fabric A has a fabric 1 embroidered with a pair of conductive wires 2 and 3 so as to form an open circuit consisting of 8 circuits and C circuits, respectively. However, sensor connection parts 4 and 5 are provided at the terminals of a pair of conductive wires 2 and 3 that constitute these eight circuits and the C circuit.

6 is a sensing sensor connected to the sensor connection parts 4 and 5, and when the fabric 1 gets wet due to urination etc. and circuit 8 and C circuit are connected at this wet part 7 and energized, the sensor 6 closes. This becomes a circuit, and the wetness of the fabric 1 is detected. At the same time, a melody generator built into the sensing sensor 6 is activated, and a melody begins to sound to notify the user and those around him/her of the wetness of the fabric 1.

Therefore, in this sensor fabric A, the wetted portion 7
has a switch function in the circuit, and while the wet part 7 is dry, a closed circuit is not formed, the detection sensor 6 is not activated, and the melody does not start playing, but if it gets wet, the melody will sound. , the wetness of the fabric 1 is notified to the user and those around him/her.

As the conductive wires 2 and 3, materials with good conductivity such as fine metal wires, metal-plated fibers, metal-deposited fibers, carbon fibers, carbon composite fibers, acrylic yarns made of copper sulfide composites, nylon yarns, or processed yarns thereof are used. Any one having the following is used as a suitable one.

Further, as the fabric 1, water-retaining woven fabrics or knitted fabrics such as polyester, polyamide, cotton, rayon, etc. are preferably used.

The 8 open circuits and the C circuit, which are embroidered on the fabric 1 using the conductive wires 2 and 3, can be embroidered in various designs and character patterns depending on the purpose of use, and the embroidery design can be changed freely.

In addition to the melody generator, the sensing sensor 6 can have a built-in generator that generates various sounds depending on the purpose, and can generate various sounds such as an alarm sound that warns of danger.

[Effect]

The sensor fabric A of the present invention is constructed by embroidering a pair of conductive wires 2 and 3 on the fabric 1 in this way, and providing sensor connection parts 4 and 5 at the terminals of the pair of conductive wires 2 and 3. For example, when used in a diaper cover, the sensor connection parts 4 and 5 of this sensor fabric A
Then, as shown in FIG. 2, the sensor fabric A is attached between the inner surface of the diaper cover 8 and the diaper 9 housed within the diaper cover 8.

When urination occurs, the moisture that has passed through the diaper 9 reaches the sensor fabric A and wets the sensor fabric A, and the wetted portion 7 connects the 8 open circuits and the C circuit formed by the conductive wires 2 and 3. It is connected and energized, forming a closed circuit through the sensing sensor 6, and the wetness of the sensor fabric A is detected. At the same time, a melody generator built into the sensing sensor 6 is activated to start playing a melody, and this melody notifies the user and those around him of the wetness of the sensor fabric A and, by extension, the wetness of the diaper 9.

As described above, when the sensor fabric A of the present invention is used in a diaper, the wetness sensing area is wide, and since the fabric 1 is soft, the sensor fabric A of the present invention does not cause discomfort or discomfort to the user, and can be used without worrying about the installation location. Furthermore, if the embroidery design is made in an anime style, for example, Doraemon, Kamen Rider Black, etc., when used on diapers for infants, the variety will be rich and the interest will be greatly increased.

The application is not limited to diapers for infants and the elderly; it can also be used for items that get wet due to urination, such as sheets and underwear, and items that get wet due to excessive bleeding, such as bandages. It can also be used as a decoration.

〔Effect of the invention〕

As explained above, in the sensor fabric of the present invention,
A pair of conductive wires is embroidered on the fabric, and a sensor connection part is provided at the end of the pair of conductive wires to provide a sensor function, so this sensor connection part detects current flow between the conductive wires. If a sensor is installed to notify the fabric, if a part of the fabric becomes wet, a pair of conductive wires will be connected at this wet area and energized, and this energization will be instantly detected by the sensor. At the same time, the melody generator built into the sensing sensor is activated and starts playing a melody, making it possible to instantly know if the fabric is wet.

In addition, if this is used in diapers, it will instantly detect wetness due to urination, etc., and a melody will start playing to quickly and reliably notify the user and those around them that the diaper is wet. , a pair of conductive wires are embroidered on the fabric to enable the sensor function to work over a wide range, making it possible to sense wetness over a wide range. In addition, the fabric embroidered with conductive wire pairs is flexible and soft, so it is resistant to external stress such as bending and bending, and it can be washed, so it can be used repeatedly without losing its functionality. be able to. Furthermore, it can be extremely easily used in diapers, etc., and will not cause any discomfort or discomfort even when worn with diapers using this sensor fabric.
