Embodiment Construction

[0038] The present invention will be further described below in conjunction with examples.

[0039] In the embodiment, the MultiRAM FT Raman spectrometer produced by the German Bruker Company is used. The Raman spectrometer uses an Nd-YAG laser with a wavelength of 1064 nm as the excitation light source, and the resolution of the spectrometer is 2 cm. -1.

[0040] Select the 6 most common pure textile fibers and 6 blended samples with known components for cross-checking (that is, use 12 samples to establish a set of characteristic peak positions of known samples, and select 1 of the 12 samples each time as The sample to be tested is inspected). 12 kinds of samples are shown in Table 1:

Abstract

The invention discloses a method for qualitative detection of Raman spectra of compositions of blend fabrics. The method is to directly detect and take the laser Raman spectra of the fabric, combine the spectrum pretreatment technology and the method for extracting, identifying and analyzing characteristic peaks, and qualitatively identify the composition sources of the fabrics. The detection method belongs to a pure optical method, needs low sample amount, does not need pretreatment, has short test time, undamaged samples during the test process and accurate test results, does not generate chemical pollutants and is suitable for qualitative detection of the compositions of various blend fabrics.

Description

Technical field [0001] The invention relates to a qualitative detection method for each component of a blended fabric by using laser Raman spectroscopy, and belongs to the field of textile materials. Background technique [0002] As a major textile country, my country has the largest textile export volume in the world. For local entry-exit inspection and quarantine bureaus, textile export inspections are arduous, and textile fiber content testing is an important item of statutory inspection. At present, in the qualitative analysis of textile content, the following textile industry standards are generally used: [0003] FZ / T 01057.1-1999 "General Instructions for Qualitative Identification of Textile Fibers"; [0004] FZ / T 01057.2-1999 "Textile Fiber Qualitative Identification and Combustion Test Method"; [0005] FZ / T 01057.3-1999 "Qualitative Identification of Textile Fibers: Microscopic Observation Method"; [0006] FZ / T 01057.4-1999 "Qualitative Identification of Textile Fiber...
