Fabric pincher elasticity tester

Abstract

The invention belongs to the textile fabric anti-crease performance measuring instrument field, in particular relates to a textile fabric crease elasticity tester which is characterized in that: the tester also comprises a camera, a microcomputer and a display unit, wherein the camera, which is arranged above a clamping device and can slide, is used to shoot the image when a textile fabric sample restores from bending; the microcomputer is used to process the image shot by the camera and to measure and calculate the numeric value of the crease recovery angle of the textile fabric sample in the image; the display unit is used to display the numeric value calculated by the microcomputer, and the numeric value is equal to the numeric value of the practical crease recovery angle of the textile fabric sample. The tester shoots the image after the textile fabric sample restoring from bending through adopting the camera with the image processed by the microcomputer, and the crease recovery angle of the textile fabric sample is automatically calculated by program, thereby ensuring the accuracy of measurement; in addition, because the tester does not adopt manual measurement basis, manual workload is also reduced.

Description

technical field [0001] The invention belongs to the field of measuring instruments for fabric wrinkle resistance, in particular to a fabric wrinkle elasticity tester. Background technique [0002] Fabric wrinkle resistance, also known as fabric wrinkle elasticity, is an important indicator of textile wearability. There are many methods for its measurement, but the most common method is to measure the crease recovery angle of the fabric folded sample. Its advantage is that it is easy to standardize and standardize, and its measurement results are relatively comparable. Whether it is a horizontal position or a vertical position, it can be divided into horizontal method and vertical method. my country is one of the few countries that adopt the vertical method, and the corresponding testing instruments developed have reached a relatively high level. Shared angle measuring device, after the sample is folded, it is pressed vertically, and after the weight is released, the sample ...

AI Technical Summary

Problems solved by technology

However, the angle measuring device in the current testing instrument usually uses a photoelectric angle test head. This angle measuring device requires personnel to align the reference point, that is, the reference point of the angle measuring device and the crease base point of the tested fabric need to be manually aligned. As a result, the manual workload is large, and errors will inevitably occur. Once there is an error in the reference position, the measured crease recovery angle of the fabric will deviate greatly, and the measurement accuracy is not high.
