Embodiment Construction

[0035] Such as figure 1 As shown, the present invention provides an image testing method and testing device for measuring the dynamic and static drape of fabrics, which can measure the drape coefficient and drape shape index of various fabric samples. The percentage of the front area ratio is the drape coefficient of the sample. The drape test software stored in the computer 8 analyzes the drape shape, and automatically measures the wave number, peak amplitude uniformity, peak angle uniformity, maximum peak amplitude, Morphological characteristic indicators such as the maximum peak angle. A kind of test method of dynamic and static drapability of fabric of the present invention is characterized in that it is realized according to the following steps:

[0036]First turn on the fabric dynamic and static drapability test device and the power switch of the computer to preheat for half an hour, prepare a circular sample 1 with a diameter of 240mm, press the down button 1122, the d...

Abstract

The invention relates to an image testing method for fabric dynamic and static drapability. The process includes the following steps: laying the sample on level plane formed by tray and light equal board, covering small disc, the lift structure lifting sample and tray, and stopping at the highest location, the sample is in overhang state; CCD camera sampling the image information into computer and display on screen, the overhang testing software distilling static index; if needing to take dynamic overhang image testing, rotating the sample and imaging, distilling dynamic overhang index; finally, output the result. The device is made up of tray, light equal board, lifting structure, rotating structure, CCD camera and computer. The relative software is stored in the computer. The invention has reliable structure and has high testing accuracy.'

Description

technical field [0001] The invention belongs to the field of textile and garment measuring instruments, in particular to an image test method and a test device for dynamic and static drape properties of fabrics. Background technique [0002] Fabric drape performance refers to the performance of the fabric to sag naturally to form a curved surface under the action of its own weight. It is an important quality of the drape fabric and an important factor that determines the visual beauty of the fabric. It is related to whether the fabric can form a beautiful curved surface when it is actually used. Styling and good fit. As a textile mainly used for clothing, it must have good drapability, especially for fabrics used for curtains, tents, and skirts, which have higher requirements for drapability. It not only requires the fabric to have good static drapability, but also requires The curved surface formed by the fabric has good volatility and liveliness, so that the fabric presen...
