Research on on-line inspection system for moisture content of fabric based on LabVIEW

摘要

This paper presents a method of moisture content detection from fabrics based on microwave. The moisture content of fabric fair influences efficiency and cost of produce. Thus, it is important to measure it exactly. Firstly, based on the absorbency effect of fabric with moisture about microwave, aiming at the requirement of most corporations for inspection and control of moisture content for fabric, the microwave technology is used to inspect moisture content, that is to say, a hygrometric scheme of microwave is designed. On this basis, the tested data are transmitted to the computer through data acquisition card and LabVIEW is applied to collect and process the data. Finally, the moisture content of textile is displayed on the computer screen. The factors affecting the measurement precision are analysed in this paper. The result shows that the method is feasible and can meet the requirement of manufacture.
