Development of correlations among the spectral, structural, and electrical properties and chemical treatment of Egyptian cotton fabric strips

Abstract

Several samples of native (untreated), mercerized (prior to ammonia treatment), and ammonia-treated Egyptian cotton fabric strips have been prepared. On these cotton samples several measurements were carried out, comprising Cu Ka X-ray diffraction analysis, Infrared absorption spectra, and the temperature dependence of the dc electrical conductivity. Detailed accounts of the spectral properties and phase constitution of NH3-treated cotton fabric strips were correlated with their electrical properties. Finally, the mechanism of electric conduction in NH3-treated Egyptian fabric strips was put forward and correlated with their spectral properties and phase constitution for the first time for cotton textile industries.

Speciation of chromium on a straw lignin: adsorption isotherm, EPR, and XAS studies

“…23 Finally, a sample of pure cellulose, giving the same NMR and X-ray photoelectron spectroscopy signals as LS, 24 was studied as a reference. It exhibited three diffraction lines, in agreement with Abou-Sekkina et al 25 (JCPDS 50-2241) and Deraman et al 26 in terms of position and relative intensities: a broad asymmetric peak at 2y ¼ 15 , corresponding to amorphous cellulose, a sharp peak at 2y ¼ 22.6 , and a small peak at 34 , corresponding to crystalline cellulose.…”

Flexible and transparent films produced from cellulose nanowhisker reinforced agarose

“…Aqueous CNWs films also showed a pattern of bright field and distribution of white dots (as presented in Figure 5f) due to their homogeneous dispersion and a percolated network of these larger domains (Xu et al, 2013). Sekkina, 1986). The CNWs were calculated to contain 89.1% crystallinity, which was also similar to the results stated in other studies (~88.6%) (Heath & Thielemans, 2010).…”

Mechanochemically activated waste‐derived cellulose as a novel functional additive to enhance melt processability and mechanical properties of poly(vinyl alcohol)

“…The degree of crystallinity can be relatively expressed by the % CrI and calculated from the XRD data. The ICSD code is 502241 in our study, according to reference . Figure shows the variation in the degree of crystallinity of WC during pan‐milling.…”
