Title:
繊維鑑別方法
Document Type and Number:
Japanese Patent JP6798885
Kind Code:
B2
Abstract:
Provided is a fiber identification method exhibiting objectivity, using a comparatively simple identification operation, and capable of identifying fibers of the same category but different type, without relying on the experience or know-how of an inspector. The method involves: obtaining absorption spectra by selecting a plurality of single fibers, the fiber type of which is known, and mixed fibers obtained by mixing the known single fibers in a series of mixing ratios as fibers for comparison, and irradiating each of the fibers for comparison with infrared rays in a wavenumber range of 4,000cm-1 to 500cm-1, excluding near-infrared rays; extracting spectrum data in a prescribed wavenumber range from these absorption spectra, and accumulating analysis data groups obtained by multivariate analysis as a database; and next, selecting a fiber, the fiber type of which is unknown, as a fiber to be tested, obtaining analysis data from the absorption spectrum of this fiber to be tested, collating with the data groups in the database, and identifying the mixing ratio and type of the fiber to be tested.
