“…The functional groups of pristine polyester fabric (C0) were measured by ATR-FTIR and Raman techniques. For the ATR-FTIR spectra are illustrated in Figure 2(a) that present two weak vibrational bands at 2967 cm -1 and 2907 cm -1 for C-H stretching, the strong peak at 1715 cm -1 corresponded to C=O stretching and also in the region bands of 1620 cm -1 and 1400 cm -1 to 1000 cm -1 assigned of C=C and C-O stretching of the aromatic ester functional groups as reported in [22] and excellent confirmed from Raman spectrum of pristine polyester fabric (C0) as given in Figure 2(b), the characteristic bands appear at 275 cm -1 of skeletal C-C deformation, at 658 cm -1 and 699 cm -1 of ring C-C stretching, at 791 cm -1 and 856 cm -1 of C-C and C-O-C bending, at 994 cm -1 , 1093 cm -1 and 1113 cm -1 of C-O and C-C stretching, at 1178 cm -1 of C-C ring stretching, at 1289 cm -1 of COO stretching, and at 1371 cm -1 , 1412 cm -1 , and 1460 cm -1 of CH2 bending [28].…”

This work aims to modify the hydrophobic coated polyester fabrics using 2%w/v ammonium hydroxide (NH4OH) at 90℃ prior and subsequently dipped in two difference aqueous zinc solution batchs containing 0.6%w/v zinc precursors with/without starch and NH4OH, finally dehydration, and characterized by the attenuated total reflection - Fourier transform Infrared (ATR-FTIR) and Raman spectroscopy (Raman), X-ray diffraction (XRD), Field emission scanning electron microscope (FE-SEM), Energy dipersive spectrometry (EDX), and Water contact angle (WCA) of 10 mL dropping at 23℃ and humidity of 63%. Raman spectra and XRD patterns results showed e-zinc hydroxide (e-Zn(OH)2), zinc oxide nanoparticle (ZnO NP) and ZnO-starch nanocomposite crystallized in the orthorhombic and hexagonol wurzite structure, respectively. The increasing intensities of Raman vibrational modes at 369 cm-1 and 750 cm-1 confirmed the increased of e-Zn(OH)2 content with additional starch, therefore, WCA trend of those finished fabric surfaces decreased. WCA optimum of 138° before washing and 136° after 5 washing cycles of the treated fabric which was activated by NH4OH acts as scourer and also as promoter of e-Zn(OH)2/ZnO NPs as revealed from ATR-FTIR result. While, other observed lower hydrophobic property after 5 washing cycles due to the hydroplilic ZnO-starch nanocomposite.e-Zn(OH)2/ZnO NPs. While others, there were observed lower hydrophobic property after 5 washing cycles due to the hydroplilic ZnO-starch nanocomposite.

“…It is clearly visible that all spectra revealed the same bands responsible for specific assignments of silk native structure, indicating no significant influence of degumming and cryogenic milling on the fibroin structure. The peak at 1660 cm −1 related to the amide I of β-sheets C=O stretching [16] is present in all spectra at comparable intensity and the same value of Raman shift. β-sheets structure of amine III is also visible for all samples as the bands at 1221 and 1256 cm −1 [17].…”

Silk Powder from Cocoons and Woven Fabric as a Potential Bio-Modifier

et al. 2021

Silk, as a protein fiber characterized by high biocompatibility, biodegradability, and low toxicity, is mainly used as textile structures for various purposes, including for biological applications. The key issue for unlimited silk applicability as a modifier is to prepare its relevant form to cover or introduce to other materials. This study presents silk powder fabrication from Bombyx mori cocoons and non-dyed silk woven fabric through cryogenic milling. The cocoons were milled before and after the degumming process to obtain powders from raw structures and pure fibroin. The powder morphology and composition were analyzed using scanning electron microscopy and energy dispersive spectroscopy. The influence of the milling on the silk structure was studied using infrared and Raman spectroscopies, indicating that silk powders retained dominant β-sheet structure. The powders were also analyzed by differential scanning calorimetry and thermogravimetric techniques. The thermal endothermic peak and onset temperature characteristic for silk decomposition shifted to the lower values for all powders, indicating less thermal stability. However, the process was found to be an efficient way to obtain silk powders. The new milled form of silk can allow its introduction into different matrices or form coatings without using any harsh solvents, enriching them with new features and make more biologically friendly.

Traces of body fluids discovered at a crime scene are a primary source of DNA evidence. Raman spectroscopy is a promising universal technique for identifying biological stains for forensic purposes. The advantages of this method include the ability to work with trace amounts, high chemical specificity, no need for sample preparation and the nondestructive nature. However, common substrate interference limits the practical application of this novel technology. To overcome this limitation, two approaches called "Reducing a spectrum complexity" (RSC) and "Multivariate curve resolution combined with the additions method" (MCRAD) were investigated for detecting bloodstains on several common substrates. In the latter approach, the experimental spectra were “titrated” numerically with a known spectrum of a targeted component. The advantages and disadvantages of both methods for practical forensics were evaluated. In addition, a hierarchical approach to reduce the possibility of false positives was suggested.
