“…As the polyethylene films proved to be too thick for transmission analysis and because of the difficulties associated with mounting the films, we resorted to a single bounce attenuated total reflection technique (2). The diamond ATR prism produces a large absorption in the region of interest limiting the available spectral range.…”

The discrimination of noncolored transparent polyethylene bags was studied by several nondestructive and semidestructive analytical methods. X-ray diffraction, infrared spectroscopy, and optical microscopy (differential interference contrast microscopy and phase contrast microscopy) were applied to polyethylene films. X-ray diffraction was used to distinguish variations in the crystalline phase, infrared spectroscopy was used to distinguish variations in the molecular components, and optical microscopy was used to distinguish the different surface morphologies. The results show that X-ray diffraction classifies the crystalline phase of the film depending on whether it is made from low-density polyethylene, linear low-density polyethylene, or high-density polyethylene; that infrared spectroscopy is useful to distinguish the molecular components and it is the most discriminating technique; and that optical microscopy discriminate films easily by their morphological differences.

“…A combination of IR spectroscopy and melting point determination was found suitable for identifying polyolefin fibers. Polypropylene fibers can be discriminated from all the other olefin types and mixtures by IR spectroscopy (426). Pairs of fibers not distinguishable by common examination procedures were shown to be differentiated by UV microfluorometry.…”

Identification of foreign fibers in yarn or fabric is of great interest to textile manufacturers. The goal of this work is to demonstrate the feasibility of single-fiber ATR-FT-IR spectroscopy to achieve prompt identification of foreign polymer brought into fibers during spinning. Testing of several fibers with different fineness proved the method's suitability for fast identification of foreign polymer. Owing to the nondestructive character of the method, the identification of foreign polymer was confirmed by other methods applied to the same samples, namely, melting temperature measurement and optical microscopy. The additional method for detection of foreign fiber by using image analysis was also applied.
