Abstract
Description
Technical Field
[0001] The present disclosure relates to an auxiliary device and a detection system for detecting the resistance of a fabric in a stretched state. Background Art
[0002] In recent years, electronic textiles have gradually developed and can be applied to the smart medical industry. For example, electronic textiles can use their conductive properties to detect heartbeats. Generally speaking, the resistance detection methods for electronic textiles include the international standards AATCC EP13 and BS EN 16812. Among them, the AATCC EP13 standard mentions that the sample should be kept flat and the resistance measurement fixture should be stable, but it does not specify the contact type for resistance measurement, such as: clamps, probes, etc. In addition, the BS EN 16812 standard recommends that the sample can be suspended and the contact points can be prepared (such as bonding, welding, etc.), but it does not mention how to avoid the weight of the resistance detection fixture causing deformation of the sample when the resistance detection fixture contacts the sample in a suspended state.
[0003] When the resistance of an electronic textile sample needs to be measured in a stretched state, it is not easy to keep the contact surface between the stretched sample and the resistance measurement fixture flat, and it is difficult to stably maintain the elongation or constant load of the sample. Therefore, the variation rate of the test results is high, which is not conducive to electronic textile developers to obtain correct evaluation data. Utility Model Content

[0011] According to some embodiments of the present disclosure, a fabric detection system includes a stretching machine and a fabric resistance detection auxiliary device. The stretching machine includes a track assembly and two opposite stretching clamps. The two stretching clamps are configured to stretch the fabric. The fabric resistance detection auxiliary device is located on the stretching machine and includes a support frame, a first clamp assembly, a second clamp assembly and a resistance measuring device. The support frame is installed on the stretching machine and includes two positioning columns separated by a distance. The first clamp assembly is movably disposed on the two positioning columns and includes a first resistance measuring clamp.

[0014] In the above-mentioned embodiment of the present disclosure, since the fabric resistance detection auxiliary device is installed on the tensile strength machine and has a first clamp assembly and a second clamp assembly, the fabric (such as a sample) can be stretched by the two tensile clamps of the tensile strength machine, and the fabric is clamped by the first resistance measuring clamp of the first clamp assembly and the second resistance measuring clamp of the second clamp assembly.

[0043] Figure 1 A three-dimensional diagram of a fabric detection system 200 according to an embodiment of the present disclosure is shown. Figure 2 Draw Figure 1 A partial enlarged view of the fabric resistance detection auxiliary device 100. Figure 1 and Figure 2, the fabric detection system 200 includes a tensile strength machine 210 and a fabric resistance detection auxiliary device 100. The tensile strength machine 210 includes a track assembly 212 and a first tensile clamp 214 and a second tensile clamp 216 relative to each other. The first tensile clamp 214 is located above the second tensile clamp 216. When measuring the resistance of the fabric F (i.e., the sample), the first tensile clamp 214 and the second tensile clamp 216 are configured to stretch the fabric F. In some embodiments, the fabric F may be a textile in the field of smart medical care, such as a textile used to detect heartbeats. The fabric F may be a conductive knitted fabric, and its material may include stainless steel, conductive ink, a wire connecting a sensor and a receiver, etc. The first tensile clamp 214 and the second tensile clamp 216 are connected to the track assembly 212 and can move up and down, so that the tensile strength machine 210 has the function of setting a fixed elongation or a fixed load of the fabric F.
[0044] The fabric resistance detection auxiliary device 100 is installed on the tensile strength machine 210. The fabric resistance detection auxiliary device 100 includes a support frame 110, a first clamp assembly 120 and a second clamp assembly 130. The support frame 110 includes two positioning posts 112 separated by a distance. The first clamp assembly 120 is movably disposed on the two positioning posts 112 and includes a first resistance measuring fixture 122. The second clamp assembly 130 is movably disposed on the two positioning posts 112 and is located above the first clamp assembly 120. The second clamp assembly 130 includes a second resistance measuring fixture 132. When measuring the resistance of the fabric F, the first resistance measuring fixture 122 and the second resistance measuring fixture 132 are configured to clamp the fabric F so as to electrically connect the first resistance measuring fixture 122 and the second resistance measuring fixture 132 for measurement.
[0045] In this embodiment, the first resistance measuring fixture 122 and the second resistance measuring fixture 132 can be pneumatic metal fixtures, which are opened and closed by air pressure control. The air pressure control is considered to be able to clamp the textile sample, maintain flatness, and measure the resistance value. For example, the air pressure value can be about 70psi. The first resistance measuring fixture 122, the second resistance measuring fixture 132 and the first tensile fixture 214 and the second tensile fixture 216 of the tensile strength machine 210 can overlap in the vertical direction D, which can improve the flatness of the fabric F during measurement.
[0046] Specifically, since the fabric resistance detection auxiliary device 100 is installed on the tensile strength machine 210 and has the first clamp assembly 120 and the second clamp assembly 130, the fabric F can be stretched by the first tensile clamp 214 and the second tensile clamp 216 of the tensile strength machine 210, and the fabric F is clamped by the first resistance measuring clamp 122 of the first clamp assembly 120 and the second resistance measuring clamp 132 of the second clamp assembly 130. In this way, when measuring the resistance of the fabric F, the contact surface between the stretched fabric F and the first resistance measuring clamp 122, and the contact surface between the fabric F and the second resistance measuring clamp 132 can be kept flat, and the elongation or fixed load of the fabric F can be stably maintained, so the variation rate of the test result is low, and the electronic textile developer can obtain correct evaluation data. In addition, the fabric resistance detection auxiliary device 100 can be applied to relevant international standard test methods for measuring fabric resistance, such as AATCC EP13, BS EN 16812 and other test methods.
[0047] In some embodiments, the distance d between the first resistance measuring jig 122 and the second resistance measuring jig 132 may be in the range of 0 mm to 750 mm, for example, 50 mm. The first resistance measuring jig 122 and the second resistance measuring jig 132 may be adjusted to a fixed point according to the stretching condition of the fabric F, for example, manually or automatically. The material of the first resistance measuring jig 122 and the second resistance measuring jig 132 may be metal, such as copper, but is not limited to copper.
[0048] In addition, the width of the fabric F may be in the range of 25.4 mm to 50.8 mm, for example, 50 mm. The first resistance measuring jig 122 and the second resistance measuring jig 132 are configured to clamp the long side of the fabric F. The first stretching jig 214 and the second stretching jig 216 of the stretching machine 210 are respectively configured to clamp the outer sides of the two opposite short sides of the fabric F, and the first resistance measuring jig 122 and the second resistance measuring jig 132 are respectively configured to clamp the inner sides of the two opposite short sides of the fabric F. In other words, the position where the fabric F is clamped by the first resistance measuring jig 122 and the second resistance measuring jig 132 is between the positions where the fabric F is clamped by the first stretching jig 214 and the second stretching jig 216.
[0049] Figure 3 Draw Figure 2A three-dimensional diagram of the fabric resistance detection auxiliary device 100 from another perspective. As shown in the figure, the first fixture assembly 120 includes a first movable plate 124, and the second fixture assembly 130 includes a second movable plate 134. The two ends of the first movable plate 124 are respectively connected to the two positioning columns 112, and the two ends of the second movable plate 134 are respectively connected to the two positioning columns 112. The first resistance measuring fixture 122 is located on the first movable plate 124, and the second resistance measuring fixture 132 is located on the second movable plate 134, so the second resistance measuring fixture 132 can be located above the first resistance measuring fixture 122 and separated by a distance. In addition, the fabric resistance detection auxiliary device 100 also includes a plurality of fixing members 126 and 136. The fixing members 126 and 136 respectively position the first movable plate 124 and the second movable plate 134 on the two positioning columns 112. In some embodiments, the fixing members 126 and 136 are pins or screws, which can be coupled to the screw holes, card slots and other structures of the positioning columns 112.
[0050] It should be understood that the connection relationship, materials and functions of the components described above will not be repeated, and will be described first. In the following description, other components of the fabric detection system 200 will be described.
[0051] Figure 4 A schematic diagram of a fabric detection system 200 according to an embodiment of the present disclosure is shown. Figure 2 and Figure 4 The fabric detection system 200 includes a tensile strength machine 210 and a fabric resistance detection auxiliary device 100. The fabric resistance detection auxiliary device 100 also includes a resistance measuring device 140. The resistance measuring device 140 is electrically connected to the first resistance measuring fixture 122 of the first fixture assembly 120 and the second resistance measuring fixture 132 of the second fixture assembly 130, and is configured to measure the resistance of the fabric F. During measurement, the first resistance measuring fixture 122 and the second resistance measuring fixture 132 contact the fabric F, and the resistance measuring device 140 can measure the resistance of the fabric F according to the distance d between the first resistance measuring fixture 122 and the second resistance measuring fixture 132. In some embodiments, the resistance measuring device 140 can be a digital ammeter.
[0052] The following table shows Figure 4 The fabric detection system 200 is applied to the fabric F (see Figure 2 )Resistance data measured at different elongations.
[0053]
[0054] The sample state is the stretched state of fabric F. As shown in Table 1, the coefficient of variation CV (%) of the resistance of fabric F measured at elongation of 0 (current state - before stretching), 10%, 20%, and 30% is in the range of 0.06 to 6.49. Therefore, the fabric detection system 200 and the fabric resistance detection auxiliary device 100 thereof have excellent contact stability for the resistance measurement of fabric F.
