In this paper, the effect of aqueous glycine treatments at different pH on the tensile properties of cotton fibers is reported. The effects on linear density and X-ray diffraction crystallinity were also evaluated. Glycine treated fibers at alkaline pH (i.e. at pH 11) produced fibers with higher linear density than control (untreated) and glycine treatments at acidic pH. The same treatment also increased strain values in cotton fibers by as much as 36%. Interestingly, similar changes in strain were observed under acidic conditions, especially at pH4, although the changes were smaller. Specific stress values normalized by the linear density measurements were not significantly different from control samples. The results of this research demonstrated improved strain properties of cotton fibers after aqueous glycine treatment at suitable conditions.

“…Cellulose nanober lm, which is a novel cellulose derivative, has excellent physical, chemical, and biological properties, such as good thermal stability, high strength, low degradation, and non-toxicity, 4,5 and it is a very promising candidate for tissue engineering, electronics, and green packaging materials. 6,7 However, hydrophilic cellulose nanober lm adsorbs water under hydrothermal conditions, which strongly affects its surface behavior and can lead to reliability problems. 8,9 Consequently, the water adsorption mechanisms of cellulose nanober lm need to be fully understood in order for this sustainable raw material to be efficiently utilized.…”

“…Steam explosion also leads to the hydrolysis of hemicellulose to water-soluble monosaccharides and oligosaccharides [ 24 ]. Steam explosion has been shown to be an efficient method for extracting cellulose from lignocellulosic materials, and has the ability to isolate CNFs [ 25 , 26 , 27 ]. However, CNFs obtained by the steam-explosion method are generally non-uniform in size and of poor quality.…”

Cellulose nanofibers (CNFs) with an average diameter of 22 nm were prepared from sugar beet pulp (SBP) via an environmentally-friendly method. Steam-explosion pretreated SBP was treated with hydrogen peroxide (H2O2) bleaching, high-speed blending, and ultrasonic treatment. Thermogravimetric analysis showed that hemicellulose was partially hydrolyzed in the steam-cooking stage, pectin was removed in the explosion stage, and lignin was removed by H2O2 bleaching. The removal of non-cellulosic components was confirmed by Fourier-transform infrared (FT-IR) spectroscopy. Morphological analysis showed that steam-explosion pretreatment largely extracted the binder materials of hemicellulose and pectin. This exposed the microfibrillated cellulosic fibers, which promoted subsequent nanofibrillation. X-ray diffraction showed that the CNFs had a crystallinity index of 62.3%. The CNFs had good thermal stability, and thus have potential for use as fillers in polymer matrices. The only chemical reagent used in this green method was H2O2. Combining H2O2 bleaching with steam explosion, high-speed blending, and ultrasonic treatment reduced the overall energy consumption and increased the efficiency of the CNFs extraction. The method, therefore, has potential application in industrial processes.
