A kind of qualitative detection method of terahertz spectrum for textile materials of students' school uniforms

Abstract

The invention discloses a terahertz spectrum qualitative detection method for textile materials of student school uniforms. First, experimental samples of different textile materials of student uniforms are produced, and then the terahertz absorbance spectrum of different textile materials is obtained by using a terahertz time-domain spectroscopy system, and the Krawtchouk moment is used to extract the terahertz absorbance spectrum. The characteristic information of the grayscale image of the terahertz absorbance spectrum is combined with the improved particle swarm algorithm and the support vector machine to establish a qualitative model, and the classification and identification model of different textile materials is obtained. Collect the textile materials on the student's school uniform, and obtain the characteristic information of the textile material on the student's school uniform, and send the characteristic information of the textile material on the student's school uniform into the classification and recognition model of the corresponding textile material for qualitative detection. The invention can use the terahertz spectrum to perform sexual detection on the textile materials of students' school uniforms, so as to ensure the quality of school uniforms for primary and secondary school students, and avoid the occurrence of safety incidents for primary and secondary school students caused by the quality of school uniforms.

Description

technical field [0001] The invention relates to the technical field of textile material identification, in particular to a terahertz spectrum qualitative detection method for textile materials of student school uniforms. Background technique [0002] With the development of the textile industry, the varieties of blended and textile colors are increasing day by day. Different textiles have made strict regulations on the type and content of their textile materials, especially in the clothing industry, illegal textile materials will cause different degrees of damage to the human body, especially in recent years, because of the types of textile materials used in school uniforms for primary and secondary school students Quality problems caused by non-compliance with standards frequently occur. In order to ensure the product quality of students' school uniforms, various types of fiber materials are often identified in the process of factory production and school acceptance. The ...
