DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

[0028] Based on the above technical features, the effects of the woven article and the method for detecting the stress distribution of the woven article under stress of the present invention will be clearly shown in the following embodiments.

[0029] Referring to FIG. 1, a medical compression stocking is taken as an example for the woven article of the present invention and comprises a woven body (1).

[0030] The woven body (1) defines more than one direction thereon, including a first direction (2) and a second direction (3) in this embodiment. A plurality of metallic yarns (4) are provided and connected on the woven body (1).

[0031] Referring to FIG. 2 to FIG. 4, the metallic yarns (4) in each direction are stacked in a layered manner such that the metallic yarns (4) are arranged on the woven body (1) in a staggered manner along the first direction (2) and the second direction (3). The distance between adjacent two of the metallic yarns (4) in the same direction is in the range of 2-4 cm. In this embodiment, the distance between adjacent two of the metallic yarns (4) in the same direction is 3 cm. Each metallic yarn (4) is connected to the woven body (1) in a criss-cross pattern. A resistance sensor (5) is connected with each of the metallic yarns (4). In this embodiment, the resistance sensor (5) is connected with each of the metallic yarns (4) in the vertical direction thereof. Referring to FIG. 5 and FIG. 6, the woven body (1) is worn on an object to be measured. In this embodiment, the medical compression stocking is worn on the user's shank. When the user does an exercise with stress on each part of the shank, the corresponding woven body (1) and the metallic yarns (4) on the woven body (1) are deformed under stress. At this time, the resistance sensor (5) (as to the resistance sensor (5), please see FIG. 3), on the metal spinning yarns (4) will detect a resistance value generated by the deformation of each of the metal spinning yarns (4).

[0032] Therefore, according to the resistance values generated by the metallic yarns (4), the stress distribution of the user's shank under stress can be obtained. As shown in FIG. 6, the metallic yarns (4) generating the resistance value in the first direction (2) and the second direction (3) are intersected to form a compressive area (6). In the figures, there are four compressive areas (6) due to the intersection. In different compressive areas (6), the stress distribution ratio of each of the compressive areas (6) can be obtained by averaging the resistance values of the plurality of metal yarns (4) in each of the different compressive areas (6).

[0033] The user uses a stress detector to measure the actual stress of one of the compressive areas (6) (using the stress detector to detect the stress on the user's shank is the prior art, so it won't be described hereinafter). The actual stress of each compressive area (6) can be obtained according to the stress distribution ratio of each compressive area (6). The metallic yarn (4) is cheaper than the stress detector. Therefore, after multiple compressive areas (6) are detected, only a single stress detector is used to detect the actual stress of a single compressive area (6) to obtain the actual stress of all the compressive areas (6). Thus, the cost of use is lower.

[0034] Furthermore, the distance between two adjacent metallic yarns (4) is 3 cm. This spacing design can detect the different compressive areas (6) on the user's shank more accurately.

[0035] Referring to FIG. 7, a plurality of metallic yarns (4A) may be combined with a woven body (1A) in three to five directions. As shown in FIG. 7, the metallic yarns (4A) are staggered in a first direction (2A), a second direction (3A) and a third direction (7A) so as to obtain a more accurate compressive area (6A). The combination of the metallic yarns in more directions can detect the compressive area more accurately. However, the metallic yarns arranged in layers in too many directions will make the final woven article too thick, so the metallic yarns combined in three to five directions will be a better design.

[0036] Referring to FIG. 8, in addition to the compression stocking, the woven article of the present invention may be made into a compression garment (8) for burns or other similar wearing apparel.

[0037] Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
