Fiber production from inorganic industrial solid wastes is an effective waste management strategy. Because of cost considerations, most enterprises generally use local solid wastes as raw materials to produce fibers. In this study, we explored the feasibility of producing fibers using fly ash and magnesium slag. The results show that the melting temperature of the blends composed of fly ash, magnesium slag, and a small amount of calcined dolomite first decreased and then increased with an increase in acidity coefficient (Mk) from 1.0 to 2.4. The samples could form a eutectic system in the Mk range of 1.4–1.8, and therefore have a relatively low melting temperature in this Mk range. Fly ash could react with magnesium slag and calcined dolomite to form akermanite, gehlenite-magnesium, and anorthite at temperatures close to the melting temperature; therefore, these crystalline phases were the main reaction products formed in the samples with Mk values lower than 1.80. Anorthite reacted further with some Na-containing and Si-containing spieces to produce labradorite. Thus, the content of anorthite and labradorite rapidly increased and they became the major crystal phases in the blend samples with Mk values greater than 1.80. MAS-NMR spectroscopic analysis revealed that the network structure of the melts depended on the ratio of bridging oxygen to non-bridging oxygen; a high ratio of bridging oxygen to non-bridging oxygen could lead to the formation of a dense network structure in the melt. The blends of fly ash and magnesium slag can be used to produce wool fibers and continuous fibers. In addition, the suitable temperature ranges for the production of both types of fibers were determined. The drawing temperature for continuous fiber production depended on the degree of polymerization and structure of the melt. 相似文献

Lyophilized wool nanoparticle powders (L-WNPP) derived from wool fibers, were extracted through the neutralization method. Here, we propose the mechanism of wool nanoparticle (WNP) formation in an aqueous solution. The effects of pH, alkali concentration, and alkali treatment time on the size and morphology of WNP were investigated. Results confirmed that WNP were well dispersed and stable in the aqueous solution and globular particles were identified with an average size of 50 nm by using 3% sodium hydroxide (NaOH) after a 4-h treatment through dynamic light scattering (DLS), zeta potential, scanning electron microscopy (SEM), and transmission electron microscope (TEM) analyses. Furthermore, fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) analyses showed that the L-WNPP maintained the chemical structure of wool protein. X-ray photoelectron spectroscopy (XPS) analysis demonstrated that higher concentrations alkaline would destroy most amide bonds of molecule chains. Moreover, L-WNPP were further used to prepare transparent protein nanoparticle films. Our results will provide guidelines for developing protein nanoparticles for biotechnology fields that require size-controlled nanoparticles. 相似文献

Abstract Anti-felting properties of knitted wool fabrics treated with chitosan were investigated, by both a laboratory scale treatment and a semi-industrial application. The influence of oxidative wool pre-treatments was analysed. The distribution of chitosan on treated wool fibres was also assessed using both qualitative and quantitative evaluation methods. The study provided shrinkage data perfectly comparable with those obtained by the currently used shrinkproofing processes, but with two important advantages: the total absence of chlorine in the process and the complete biodegradability of chitosan. The semi-industrial treatment showed the complete reproducibility of the laboratory scale results, giving rise to the possibility of an industrial adaptation of the process. 相似文献
