“…In addition to being an abundant byproduct of the poultry industry, feather fibers have a relatively low density of 0.8 g/cm 3 and have good thermal and acoustical insulating properties 5, 6. These properties result from the air pockets within the keratin filaments of the feathers 7. These characteristics qualify feather fibers as excellent candidates for bulk quantity, inexpensive, lightweight, low‐load bearing composite applications such as interior paneling and furniture in automotives, trucks, homes, offices, and factories.…”

Composites made of feather fiber (Ff), kraft pulp fiber (Pf), polypropylene (PP), and maleic anhydride modified polypropylene (MaPP) were tested in tension and three-point bend tests. Composite panels were compression molded from multiple plies of nonwoven, fabric-like prepreg manufactured with wetlay papermaking equipment. Composites containing all four materials were manufactured with MaPP substitutions for PP of 0 -10 wt % at 2 wt % increments. The best mechanical properties were observed with a substitution of 8 wt % MaPP. Composites containing either Pf or Ff were manufactured with MaPP substitutions for PP of 0, 4, and 8 wt %; mechanical properties improved with increases in MaPP content. The improvements in mechanical properties were attributed to fiber/ matrix interface improvement by the addition of MaPP. Scanning electron microscopy revealed evidence of improved interfacial bonding on the tensile fracture surfaces.

“…Biosorption is characterized as a process independent of physicochemical metabolism that results in the removal of biological materials from the solution. The process was historically used to extract metals and associated materials [26][27][28][29][30][31][32][33][34], but the application is now being extended to remove other organic target substances such as dyes, steroids, pharmaceuticals, medicines and pesticides [35][36][37]. A variety of experiments have been performed on the adsorption of glyphosate using different materials such as biopolymer membrane, resin, magnetic nanocomposite and readily accessible activated carbon and biochar [38][39][40][41].…”

Generally, in nonlinear regression, the residuals of the curve must be distributed normally, and residuals must be tested for the presence of outliers. This is normally done using normality tests such as the Kolmogorov-Smirnov, Wilks-Shapiro and D'Agostino-Pearson and the Grubb's test, the latter test for the presence of an outlier, which is the focus of this study. Normality tests for residues used in general nonlinear regression revealed that the usage of the pseudo-1st order model in the fitting of glyphosate biosorption to palm oil fronds was adequate due to lack of an outlier. The Grubbâ€™s test was applied to the residual results. The critical value of Z from statistical table for Grubbsâ€™ test for a single outlier using mean and SD was 2.289 (n=10). The Grubbs (Alpha = 0.05) g value was 1.844. As the test statistic is lesser than the critical assigned value, no outlier was deemed present.

“…Recently, much research has focused on the sorption properties of feathers as sorbents for removal heavy metals, phenol and organic dyes from their aqueous solutions [9][10][11][12][13][14]. However, most papers are only studied the sorption properties of feathers just by immersing them in metal ion solutions.…”

In this paper, duck feather fiber was treated by alkaline solution first, then its Cu2+ sorption capacity was tested and the sorption mechanism was studied by utilizing infrared spectrum (FTIR) and wide-angle X-ray diffraction (XRD). Moreover, desorption properties of the treated duck feather fiber were investigated in order to exploit it as a recycled industrial effluent treatment material. At last, duck feather fiber was air-laid and thermal-bonded into a kind of composite nonwoven fabric by adding bicomponent low melt PE/PP fiber as binder fiber. It is found that duck feather/bicomponent PE/PP fiber composite nonwoven fabrics show good mechanical properties and Cu2+ and Cr6+ sorption capacity. It is a promising material for textile dying effluent treatment.
