Method for detecting pressure distribution of knitted fabric under pressure

The invention relates to a method for detecting the pressure distribution of a knitted fabric under pressure, and particularly to an invention that uses the change in resistance value of a knitted fabric under pressure to obtain the pressure distribution.

People who are sedentary, long standing, poor posture, or excessive exercise sometimes cause varicose veins in the legs, or sore shoulders, necks, and waists. At this time, muscle pressure will also change.

That is, by obtaining abnormal changes in muscle pressure, you can immediately correct poor posture or know that you should rest.

Knowing the way to know the changes in muscle pressure, you must use many pressure detectors to attach to the muscles to obtain changes in muscle pressure.

However, the price of pressure detectors is high, and using many pressure detectors to learn the pressure on the muscles requires a relatively expensive cost.

Therefore, the present invention provides a method for detecting a pressure distribution of a knitted fabric under pressure, including the following steps: defining more than one direction on a knitted body; connecting a plurality of metal spinning yarns to the knitted body and arranging them at intervals, and each Metal spinning extends along the direction; a pressure is applied to the knitted body, and a resistance sensor senses a resistance value generated by the metal spinning on the knitted body; according to the resistance sense that generates the resistance value Measuring device to know the pressure distribution of the knitted body after being compressed.

Further, the aforementioned metal spinning is combined in multiple directions of the weaving body, so that the aforementioned metal spinning is staggered; the metal spinning of different directions which generate the resistance value intersects to form a compression zone, and the compression zone After the resistance values of multiple metal spinning yarns in each compression zone are averaged, the pressure distribution ratio of each compression zone can be obtained; after measuring the actual pressure in one compression zone, the ratio can be obtained according to the ratio. The actual pressure in each compression zone.

Furthermore, the metal spinning is combined in 3 to 5 directions of the woven body, so that the metal spinning is staggered in the 3 to 5 directions, so as to obtain the compressed area.

The present invention further proposes a knitted fabric that can use the foregoing detection method, including: a knitted body, defining more than one direction on the knitted body; connecting a plurality of metal spinning yarns to the knitted body and arranged at intervals, and each The metal spinning yarn extends in this direction; a resistance sensor is connected to each of the metal spinning yarns.

Further, the distance between two adjacent metal spinning in the same direction is between 2 cm and 4 cm. Furthermore, the distance between two adjacent metal spinning yarns in the same direction is 3 cm.

Further, the metal spinning is combined in 3 to 5 directions of the weaving body, so that the metal spinning is staggered in the 3 to 5 directions to obtain the compressed area.

Further, the resistance sensor is connected to each metal spinning yarn in a vertical direction of the each metal spinning yarn.

Further, each metal spinning yarn is connected to the woven body with a Roman weaving structure.

According to the above technical features, the following effects can be achieved:

1. After the knitted fabric is compressed, the pressure distribution can be known through the change of resistance value. When there are multiple regions under pressure, the ratio of the resistance value between the compressed regions can be known, so it can measure a single impact. The actual pressure in the nip can be obtained according to the ratio of the resistance value.

2. Metal spinning is cheaper. After measuring multiple compressed areas, only a single pressure detector is needed to detect the actual pressure of a single compressed area, and the actual pressure of all compressed areas can be obtained. low.

Based on the above technical features, the main effect of the method for detecting the pressure distribution of the knitted fabric of the present invention under pressure will be clearly shown in the following embodiments.

Referring to the first figure, the knitted fabric of this embodiment takes a compression stocking as an example, and includes: a knitted body (1), and more than one direction is defined on the knitted body (1). This embodiment includes a first direction (2) and a second direction (3); connecting a plurality of metal spinning yarns (4) to the knitted body (1).

Referring to the second to fourth figures, the metal spinning (4) in each direction is stacked in a layered manner, so that the aforementioned metal spinning (4) follows the first on the knitted body (1). One direction (2) and the first The two directions (3) are staggered at intervals, and the distance between the two adjacent metal spinning yarns (4) in the same direction is between 2 cm and 4 cm. In this embodiment, the two adjacent metal spinning yarns in the same direction ( 4) The distance is 3 cm, and in which, each metal spinning yarn (4) is connected to the woven body (1) with a Roman weaving structure; a resistance sensor (5) is connected to each metal spinning yarn. Yarn (4). In this embodiment, the resistance sensor (5) is connected to each metal spinning yarn (4) in the vertical direction of each metal spinning yarn (4). Referring to the fifth and sixth figures, the knitted body (1) is worn on an object to be measured. In this embodiment, the compression socks are worn on the user's calf. When the user moves, the parts of the calf After being subjected to pressure, the knitted body (1) and the metal spinning yarn (4) on the knitted body (1) corresponding to the pressure-bearing area will be deformed by compression. At this time, the resistance of the metal spinning yarn (4) is sensed. The sensor (5) [see the third figure for the resistance sensor (5)] will sense a resistance value generated by each metal spinning yarn (4) due to compression deformation.

Therefore, the pressure distribution after the user's calf is compressed can be obtained from the metal spinning yarn (4) that generates the resistance value. That is, as shown in the sixth figure, the metal spinning (4) that generates the resistance value in the first direction (2) and the second direction (3) intersects to form a pressure region (6). There are four compression zones (6) due to the intersection. After averaging the resistance values of multiple metal spinning yarns (4) in each compression zone (6) among different compression zones (6), the Proportion of pressure distribution in each pressured zone (6).

After the user measures the actual pressure in one of the compression zones (6) with a pressure detector, [using the pressure detector to detect the pressure on the user's calf pressure-bearing area is a known technology, which is not special here. [Explanation], according to the pressure distribution ratio conversion of each pressure zone (6), the actual pressure of each pressure zone (6) can be obtained. The price of metal spinning (4) is cheaper than the pressure detector, so after measuring multiple compressed areas (6), only a single pressure detector is needed to detect the actual condition of a single compressed area (6). Pressure, you can get the actual pressure of all the pressure zone (6), so the use cost is low.

It should be further explained that the distance between two adjacent metal spinning yarns (4) is 3 cm, and the design of this distance can more accurately detect different compression areas (6) on the user's calf.

Referring to the seventh figure, further, a plurality of metal spinning (4A) can be combined in 3 to 5 directions of a knitted body (1A), as shown in the seventh figure, the aforementioned metal spinning (4A) is first The directions (2A), a second direction (3A), and a third direction (7A) are staggered to obtain a more accurate compression zone (6A). Combining metal spinning in more directions can certainly detect the compression zone more accurately. However, arranging metal spinning in layers in too many directions will make the final knitted fabric too thick. Therefore, combining in 3 to 5 directions Multiple metal spinning will be a better design.

Referring to the eighth figure, in addition to the compression socks, the knitted fabric of the present invention can also be made into a pressure garment (8) or other similar wearing items for burns.

Based on the description of the above embodiments, the operation, use and effects of the present invention can be fully understood, but the above-mentioned embodiments are only preferred embodiments of the present invention, and the implementation of the present invention cannot be limited in this way. The scope, that is, the simple equivalent changes and modifications made according to the scope of the patent application and the description of the invention, are all within the scope of the present invention.
