Abstract

The invention provides a device for online measurement of the form of the spherically-compressed surface of a textile material. The device is characterized in that the device comprises a box body, a compression mechanism and a displacement mechanism, a light source and a camera are arranged in the box body, and a first calibration board is engraved on the left side wall of the box body; a third calibration board is engraved on the front wall of the box body; a second calibration board is engraved on the bottom wall of the box body and the textile material is fixed to the second calibration board; the compression mechanism comprises a sliding rod, a pressure sensor, a fixedly-connecting rod and a hemisphere, one end of the sliding rod is connected with the displacement mechanism and can be driven by the displacement mechanism to move vertically, and the other end of the sliding rod is fixedly connected with the pressure sensor; one end of the fixedly-connecting rod is fixedly connected with the hemisphere and the other end of the fixedly-connecting rod is fixedly connected with the pressure sensor. According to the device and method, the form of the surface of the textile material in the spherically-compressed process can be measured on line, especially the form of the surface of a contact zone between a component of the compression mechanism and the textile material can be measured on line, and the relation between a spacer fabric structure and the compression performance can be clear.

Description

technical field [0001] The invention relates to an on-line measurement device and method for the surface morphology and contact profile of textile materials during spherical compression. In particular, certain optical principles and image processing techniques are applied to obtain the contact between the sphere and the fabric surface when the fabric surface is spherically compressed. The online measurement method and device of the three-dimensional form. Background technique [0002] As a kind of textile material, spacer fabric is very popular in medical mattress and cushion products because of its typical three-dimensional structure composed of upper and lower surface layers and intermediate spacer wire interlayer, which has good moisture permeability. Although there are more and more applications of spacer fabrics, one of the keys to the interaction between spacer fabrics and the human body is the analysis of compressive mechanical behavior, so as to guide and improve the...
