specific Embodiment

[0080] Select cotton and viscose textile materials commonly used in the production of school uniforms for primary and middle school students to make 6 kinds of mixture experimental samples with different proportions: use cotton and viscose textile materials, and make 100% cotton samples according to the method of making 5 pieces of cotton textiles For the sample, the sample made of 4 pieces of cotton and 1 piece of viscose fiber has a cotton content of 80%, and the viscose fiber is placed in the middle of the cotton cloth. In the textile materials with a large number of sheets, as shown in Table 1. The two kinds of textile fabrics are provided by the National Rubber and Rubber Products Quality Supervision and Inspection Center (Guangxi), which meet the national production standards, so they are selected as samples for this experiment.

Abstract

The invention discloses a textile material terahertz spectrum quantitative detection method, which is characterized in that a terahertz time-domain spectroscopy technology is utilized to carry out quantitative analysis on textile material cotton and viscose fiber contents so as to realize detection on the content of a certain component in a multi-component mixture textile, a cuckoo search algorithm is used to optimize a quantitative analysis model to obtain a good quantitative detection result, and a linear adaptive step length is introduced to improve the cuckoo search algorithm so as to improve the convergence and optimization capacity of the cuckoo search algorithm and obtain an optimal solution, so that the quantitative detection precision is further improved, and the technical problems that in the prior art, a textile inspection method is complex in procedure and low in accuracy are solved.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a terahertz spectrum quantitative detection method for textile materials. Background technique [0002] With the development of my country's textile industry, there are more and more varieties of blended fabrics and textile designs and colors. Different textiles have strict regulations on the types and contents 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 content of textile materials used in school uniforms for primary and middle school students. Quality problems caused by non-compliance with standards have occurred frequently. Therefore, it is particularly important to strictly test the quality of school uniforms and quantitatively identify textile materials. Currently, the detection of textiles often requires the combined use of mul...
