[0002] Clothing material is the abbreviation of clothing material and its surface texture. Among the three basic elements of clothing design: shape, color and material, material is the most basic material basis for clothing and is also the medium on which clothing shape design depends.

[0003] Existing clothing fabrics need to be tested during processing, one of which is the tensile test, that is, how much tension the fabric can withstand before it is damaged. The traditional testing method is to fix the tension detector on both sides of the fabric, apply tension manually from the outside, and read the reading of the tension detector when the fabric is critically damaged. The operation of this process is extremely cumbersome, and then a numerical curve graph between force and elongation is obtained through the supporting measurement and control instruments.

This method brings the following advantages:

[0018] (1) In order to solve the problem that the results of existing clothing fabric measurements are not convenient to read, the present invention proposes a measurement indicator assembly. First, the present device is inverted so that the measurement indicator assembly faces downward. At this time, the engaging spikes cannot pierce the top hemispherical shell. When testing is required, multiple sets of fabric bodies to be tested are placed flat into the measurement accommodating tube and the through-indicator shell. At this time, the multiple sets of fabric bodies can just limit the movement of the hemispherical container and the top hemispherical shell. The present device is flipped over and reset. Due to the limitation of the multiple sets of fabric bodies, the hemispherical container and the top hemispherical shell cannot move downward, but are attached to the hemispherical shell. The plurality of fabric bodies are put on the plurality of fabric bodies, and the driving motor is started, so that the ball screw rotates and drives the moving platform to move on the ball screw and the screw guide rail, so as to adjust the position of the clamping groove on the V-shaped clamping rod, so as to facilitate clamping of the two ends of the fabric body, and the hydraulic cylinder is started to control the output end of the hydraulic cylinder to eject, so as to drive the transmission connecting rod to move through the clamping moving plate, so that the V-shaped clamping rods are brought closer to each other, so as to clamp the ends of the plurality of fabric bodies through the clamping groove, so as to realize the rapid clamping of the fabric body, and the shape of the fracture of the fabric body can be measured through the horizontal measuring scale;

[0019] (2) Control the driving motor to drive the two sets of moving platforms to move to both sides, thereby stretching the multiple sets of fabric bodies. When the multiple sets of fabric bodies are broken, a set of hemispherical containers and the top hemispherical shell located above the broken part can move downward, and the telescopic head pushes the hemispherical container and the top hemispherical shell to move downward through the telescopic rod and the telescopic spring. The engaging spikes can continuously adhere to the outer walls of the hemispherical container and the top hemispherical shell due to the setting of the engaging spring. When the hemispherical container and the top hemispherical shell move downward until the engaging spikes contact the top hemispherical shell, the engaging spikes pierce the top hemispherical shell, and the internal suspension is discharged from the limit. The liquid flows into the through-hole shell, and the broken parts of the multiple fabric bodies can be filled. The control button is pressed immediately, and the internal circuit causes the parallel plate capacitors to discharge continuously, so that the suspension entering the through-hole shell changes from liquid to solid. The suspension made of the electrorheological fluid and the pigment powder can mark the broken parts of the multiple fabric bodies significantly and eye-catchingly, maintain the shape of the multiple fabric bodies at the moment of break, and indicate the specific position of the break. It can be clearly observed through the transparent through-hole shell, the operation is simple, and the test results can be read more directly. BRIEF DESCRIPTION OF THE DRAWINGS
