Fabric three-dimensional pressure simulation test system

Abstract

The invention relates to a fabric three-dimensional pressure analog test system which is used for testing the dynamic contact pressure and the pressure attenuation characteristics of fabrics. The measuring principles of the invention refers to measuring dynamic clothing pressure during a process of fabric three-dimensional deformation by a pressing ball embedded with nine highly precise pressure sensors to press against the fabrics; the pressing ball is transmitted by a driving device, which can press against the fabrics for more than several thousand times so as to measure pressure fatigue. A pressure-displacement curve, a pressure-time curve and a pressure attenuation curve of each sensing point are respectively obtained by the processing of a computer. The analog test system of the invention has simple structure and convenient operation and is a testing instrument that can effectively and objectively evaluate fabric pressure performance.

Description

Technical field [0001] The invention belongs to the technical field of textile precision measuring instruments, and particularly relates to a testing system for the contact pressure and pressure fatigue characteristics of fabrics (knitted fabrics, woven fabrics, non-woven fabrics and their composite materials), and is suitable for dynamic contact pressure and pressure attenuation characteristics of fabrics Test. Background technique [0002] Clothing pressure is one of the important indicators to evaluate the comfort, functionality and safety of pressure clothing. However, the development of clothing pressure testing institutions and testing instruments lags far behind the needs of scientific research, and there is no reasonable and unified testing standard. So far, there is no instrument for fabric pressure testing similar to the present invention. Similar instruments that are similar in structure, such as the electronic burst strength tester, are mainly used to test the burst...

Problems solved by technology

[0005] 1. The pressure-sensitive components have a certain size and thickness. In some occasions with low requirements, such as testing the pressure of sanitary socks and medical bandages on the human body, it is more common to use them, while underwear and tights with greater stretchability Bras, etc., will deform the garment during the test, and it is difficult to accurately measure the pressure of the garment

[0006] 2. Human influence factors are relatively large, difficult to control, complicated to operate, poor reproducibility of test results, not comparable

[0007] 3. It is not possible to detect dynamic pressure at the same time, that is, the change of pressure over time under the condition of three-dimensional deformation of the fabric

[0008] 4. The pressure fatigue characteristics cannot be detected, and it is difficult to form a more objective test and evaluation of the pressure performance of a certain type of fabric
