“…wood). 9,10 These fiber types, except for the tree fibers from wood, have been extensively used for clothing, domestic woven fabrics and ropes for thousands of years. Due to their wide availability, low cost, good recyclability, low density and high-specific mechanical strength, over the last years there has been an increased interest for application as reinforcements in polymer matrix composites, e.g., in the automotive and construction industries.…”

On the Identification of Rayon/Viscose as a Major Fraction of Microplastics in the Marine Environment: Discrimination between Natural and Manmade Cellulosic Fibers Using Fourier Transform Infrared Spectroscopy

et al. 2016

This work was sparked by the reported identification of man-made cellulosic fibers (rayon/viscose) in the marine environment as a major fraction of plastic litter by Fourier transform infrared (FT-IR) transmission spectroscopy and library search. To assess the plausibility of such findings, both natural and man-made fibers were examined using FT-IR spectroscopy. Spectra acquired by transmission microscopy, attenuated total reflection (ATR) microscopy, and ATR spectroscopy were compared. Library search was employed and results show significant differences in the identification rate depending on the acquisition method of the spectra. Careful selection of search parameters and the choice of spectra acquisition method were found to be essential for optimization of the library search results. When using transmission spectra of fibers and ATR libraries it was not possible to differentiate between man-made and natural fibers. Successful differentiation of natural and man-made cellulosic fibers has been achieved for FT-IR spectra acquired by ATR microscopy and ATR spectroscopy, and application of ATR libraries. As an alternative, chemometric methods such as unsupervised hierarchical cluster analysis, principal component analysis, and partial least squares-discriminant analysis were employed to facilitate identification based on intrinsic relationships of sample spectra and successful discrimination of the fiber type could be achieved. Differences in the ATR spectra depending on the internal reflection element (Ge versus diamond) were observed as expected; however, these did not impair correct classification by chemometric analysis. Moreover, the effects of different levels of humidity on the IR spectra of natural and man-made fibers were investigated, too. It has been found that drying and re-humidification leads to intensity changes of absorption bands of the carbohydrate backbone, but does not impair the identification of the fiber type by library search or cluster analysis.

“…Cellulose, a polysaccharide, is the main compound of hemp shiv, and generally of biomaterials originating from crop. Cellulose is a strong natural polymer, which keeps its integrity via the hydrogen bonds between the different hydroxyl groups of two glucose units, forming a solid microcrystalline structure (Ciechańska et al 2009). Despite its name, hemicellulose is not a type of cellulose as it contains different sugar units, and exhibits a high degree of branching with other groups, making it a non-crystalline structure (John and S. Thomas 2008).…”

“…Cotton, a natural cellulosic fiber, is popular in the textile industry with a long history due to its superior characteristics of moisture permeability and comfort-dressing [ 1 ]. However, compared with wool, silk, and some synthetic fibers, the flash point and ignition point of cellulosic fibers are lower with a limiting oxygen index (LOI) of 18.4% [ 2 , 3 , 4 ], which are considered as flammable or combustible materials that can easily cause fire accidents, environmental hazards, personal injury, and property losses [ 5 ].…”

Metal–organic frameworks (MOFs) have great potential for the development of fire barriers for flammable materials. Accordingly, zirconium-based metal–organic framework (Zr-MOF), branched polyethyleneimine (BPEI), and vinyltriethoxysilane (VTES) were deposited to produce composites assembled on cellulosic fibers to investigate their barrier effects. The structure, morphology, and thermal properties of the cellulosic fibers were characterized using FTIR spectroscopy, SEM, and TGA. Compared with the untreated cotton sample, the temperature of the maximum rate of weight loss (Tmax) of C-Zr-MOF/BPEI/VTES increased from 479 to 523.3 °C and the maximum weight loss rate (Rmax) at Tmax decreased from 37.6 to 17.2 wt%/min. At 800 °C, the pristine cotton was burned out without residues whereas the residual char content of the C-Zr-MOF/BPEI/VTES sample was 7.2355 wt%. From the vertical burning tests, the results suggested that the C-Zr-MOF/BPEI/VTES sample had better barrier effects by reducing the flame-spread speed and generating more protective char layers.
