Near Infrared Spectra of Origin-defined and Real-world Textiles (NIR-SORT): A spectroscopic and materials characterization dataset for known provenance and post-consumer fabrics

This database contains Near Infrared (NIR) spectroscopy and optical microscopy data on an assortment of fabric specimens used for applications including fiber content classification, systems and software development, and systems and process validation of textile feedstock identification systems.The fabric sample library includes 113 fabrics total: 70 known provenance fabrics with known fiber content and various dyes/finishes, 20 known provenance fabrics with undyed, blended fiber content, 11 post-consumer fabrics with various fiber contents, dyes, and finishes, and 12 pre-consumer fabrics with various fiber contents, dyes, and finishes.Each fabric was measured via NIR spectroscopy with nominally seven replicates on a benchtop instrument from 833 nm to 2500 nm and two handheld instruments from 1550 nm to 1950 nm. Optical microscopy images for these fabrics were collected on a benchtop, stereo-ocular inspection microscope with mono, color, or polarized cameras.The data repository includes directories for: benchtop NIR spectral data, handheld NIR spectral data, and fabric-scale microscopy images.For more information, please see the readme and data documentation in each sub-directory. A complete manuscript describing data collection, analysis, and database documentation is forthcoming. Spectroscopy data consists of about 193 MB from ca. 4248 files. Microscopy data consists of about 10.6 GB from ca. 1044 files. Specimen files are .zipped at the Source directory level to reduce large number of files.File Formats: .csv, .xlsx, .txt, .pdf, .bmp, .tiff, .py, .sh
