Description

Fabric drapability tester control system with timing device

Technical Field

The utility model relates to a control system of fabric drapability tester.

Background

The drapability style test of the fabric is a research subject which is more important in the industry in the last decades of the world, and the research level in the industry in China is at the top of the world. Taking a skirt as an example, the drapability style of the skirt from the home life of a wearer to the stage art does not show the beautiful characteristics of the skirt. How to evaluate the drapability style of the fabric is in front of professionals in the industry. Due to the limitation of certain specific indexes of the fabric, the fabric drapability style is researched, and objective evaluation is made by using an instrument, so that the method is an exploration subject of professionals in the industry. In recent decades, the static drapability style test instruments of the fabric are from the very beginning, undergo a long exploration stage and are nearly mature at present. Fabric drape style testing is currently done on a test instrument known as a "fabric dynamic drape style tester".

The test plate as a test platform is improved from a static state to a dynamic state, the rotating speed is adjustable, a display device displays the rotating speed in real time, a key step is taken from the static state to the dynamic state, and effective test results approved by experts in the industry are made for the test evaluation of the dynamic drapability style of the fabric.

The effect on the drape reproducibility index is the placement of the sample on the test plate. The placing method before the test of the sample has great influence on the measured result, so the placing method of the sample on the detection disc is improved for many years, and the improved method comprises the following steps of placing the sample at a low position and obtaining a static image at a high position: after the periphery of the sample is uniformly laid on the background platform for placement at the low position, the switch of the lifting motor is turned on, the detection disc drives the sample to enable the periphery of the sample to gradually and uniformly break away from the background platform and rise to the high position, and a static image is obtained after the sample reaches the high position. The measured result shows that the consistency and the reproducibility of the measured result of the sample loading and placing method are good.

Recent studies on fabric drape found that: the dynamic drapability index of the fabric is also verified by theory by the fact that the rotating motor capable of adjusting the speed is designed at the lower end of the detection disc through improvement and is rotated by turning on a 'dynamic/static' switch, and the detection disc drives the sample to rotate.

The applicant found in the course of research that: after the sample is loaded at a low position and reaches a high position, a sample stabilizing process is needed, a static image is obtained after the sample is stabilized, and the stabilizing time is timed after the sample reaches the high position; the dynamic images can be stably acquired by the detection disc for a long time after the detection disc drives the sample to rotate, and the stable time needs to be arranged in the testing process. Therefore, in the testing process, after the rotation speed of the detection disc is adjusted, the sample is loaded on the detection disc when the detection disc is at a low position, the 'lifting' switch is turned on, and after the detection disc reaches a high position, the operator controls the camera system to obtain a static image of the sample; and then turning on a 'rotation' switch, starting the rotation of the detection plate, and acquiring a dynamic image through the camera system when the operator feels that the rotation of the sample is basically stable. During the whole test process, an operator holds the stopwatch in one hand, operates the lifting switch, the rotating switch and the image acquisition button in the other hand, and then the task of testing the static and dynamic drapability style characteristics of the fabric is completed. For the time control technology for testing the static and dynamic drapability style characteristics of the fabric, a stopwatch timing mode is used for increasing the operation difficulty for an operator in the testing process, and the normalized operation is difficult to realize.
