Abstract

The invention provides a measuring device and method for the deformation shape of the spherical compressed surface of textile materials. The measuring device for the spherical compression surface deformation form of textile materials is characterized in that it comprises a box body, a light source and a camera are arranged in the box body, and a first calibration plate is engraved on the left side wall of the box body; the bottom of the box body A second calibration plate is engraved on the wall, and the textile material is fixed on the second calibration plate. The invention can realize the measurement of the surface deformation of the spacer fabric after spherical compression, and helps to clarify the relationship between the structure of the spacer fabric and the compression performance.

Description

technical field [0001] The invention relates to a testing device and method for the surface deformation form and contact profile of textile materials under spherical compression, especially a method for obtaining the three-dimensional form of the fabric surface under compression by applying certain optical principles and image processing techniques and device. Background technique [0002] The spacer fabric is a textile material with a typical three-dimensional structure composed of the upper and lower surface layers and the middle spacer wire interlayer. It has a flexible and elastic three-dimensional space structure, endowing it with good compression resilience, and has been widely used in automotive interior decoration, functional Clothing, padding materials and other fields, especially in the application of mattresses, can be abstracted as a study on the structure and performance of the compression interaction between a spherical hard object with a certain curvature and ...
