Structure of melt-spun mono- and bicomponent filaments. 'High-resolution 2D Raman mapping of mono- and bicomponent filament cross-sections'. For more information, see the publication by E. Presented analysis techniques and results thereof are (i) Raman mapping of filament cross-sections: 2D maps of peak positions, widths, peak area ratios (ii) attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR): ATR-FTIR spectra and extraction of surface crystallinity (iii) wide-angle x-ray diffraction (WAXD): WAXD patterns and extraction of average crystallinity (iv) small-angle x-ray scattering (SAXS): SAXS patterns and determined crystallite sizes and long-spacings (v) differential scanning calorimetry (DSC): thermograms and extracted average crystallinity as well as thermal properties (vi) atomic force microscopy (AFM): AFM image of the surface of an embedded fiber cross-section.
The diameters of the single filaments range from 27 µm to 79 µm. A quick analyzing method because the ATR sample compartment does not require sample preparation.This data in brief article summarizes structural data obtained from monocomponent melt-spun and offline drawn poly(ethylene terephthalate) (PET) monofilaments, as well as from melt-spun bicomponent core-sheath PET-polyamide 6 (PA6) filaments.Scan Speed: 3 velocities, 2.2 - 20 kHz (1.4 - 12.7 mm/sec opd)ĭetector: DigiTect TMdetector system, High sensitivity DLATGS.
Interferometer: RockSolidTM, Permanent aligned, high stability Wavenumber Accuracy: Better than 0.01 cm -1 (at 2000 cm -1) Resolution: Better than 1 cm -1 (apodized)
Spectral range: 7500 - 370 cm -1 (with standard KBr beamsplitter) Nopea menetelmä, koska ATR-mittauskammio ei vaadi juurikaan näytteen esikäsittelyä.
