“…Since per unit weight of a fiber with a higher bulk density will have less volume, the surface area for reaction with the absorption media will be lower. This finding is consistent with previously reports on the relationship between bulk density and water absorption of various plant fibers, including oak and CBS (Bajwa et al 2011). Overall, the affinity of the natural fibers for water was stronger than for oils (Fig.…”

Most plant fibers are good sorbents of oil; however, synthetic sorbents have a much higher sorption capacity (SC) than plant fibers. This study evaluated the effect of fiber treatments, specifically hot-water treatment and mercerization, on the absorption characteristics of selected plant fibers. Five common plant fibers-corn residues, soybean residues, cotton burr and stem (CBS), cattail, and oak-were evaluated for their absorption characteristics in crude oil, motor oil, deionized (DO) water, and a 80:20 mix of DO water. The fiber treatments included ground fiber (control), hotwater treatment at 80 °C for 4 h and 125 °C for 4 h, mercerization at room temp for 48 h, and mercerization at 300 °C for 1 h. The absorption capacity (AC) varied with fiber type, absorption medium, and fiber treatment. Mercerization at 300 °C increased the water absorption of soybean residue up to 8 g/g. Mercerization at room temperature and the hot-water treatment at 125 °C increased the crude oil absorption capacity. After certain treatments, the crude oil absorption capacity of CBS and corn fibers increased over 5 g/g, and the motor oil absorption capacity of cattail, corn, and soybean also increased to 4 to 5 g/g.

“…The ethanol extractives from these pretreatments were 3-5%. These results agreed with values reported by Bajwa et al (2011), who analyzed the cotton linters, cotton burrs, and sticks separately.…”

“…Agblevor et al (2006) reported lignin content of 21-24% for CGT samples from four different gins; a higher lignin content was found in the studies with cotton stalks, where lignin contents were 30.1% and 27.8%, respectively (Silverstein et al, 2007;Akpinar et al, 2007). Lower lignin contents were found in the studies of Bajwa et al (2011) in cotton linters (8.9%) and Philippoussis et al (2001) in cotton wastes (10.15%); however, these two wastes were composed of less recalcitrant parts of CGT, which explains their low lignin content (Philippoussis et al, 2001;Bajwa et al, 2011). The greatest (Silverstein et al, 2007) decrease in the lignin content was in U + HW + E (10%) and HW + E (11%) pretreated biomass.…”

“…The lignocellulosic fibers were normally swelled in the diameter direction, that is, perpendicular to the length direction. Somehow, a minority of the fibers remained randomly-oriented, which contributed to the comparatively lower width and length swelling (Bajwa et al 2011). In general, the experimental results for the orthotropic swelling represented by symbols were found to fit closely with the polynomial curve.…”

High-fiber-content composites made from rice husk (RH) (from 50 up to 80 wt%) as well as a recycled thermoplastic blend (rTPB) were fabricated using a two-step extrusion and hot/cold press molding technique. The temperature dependency of the thermal degradation and dynamicmechanical behavior was investigated using thermogravimetric analysis (TGA) and dynamic mechanical analysis (DMA). The long-term water absorption and orthotropic swelling were analyzed following immersion in distilled, tap, and sea water for 15 weeks. Improvements in the thermal stability, storage, and loss modulus, as well as reductions in dimensional stability, were observed as the alkali content of the RH in the rTPB composites was increased. The composites immersed in sea water showed the lowest water absorption, followed by those in distilled and then tap water. The thickness dimension of the composite specimens exhibited the highest swelling values, followed by width and then length dimensions. The tensile strength and elastic modulus showed the maximum values at 70 wt% RH (21.2 MPa and 1.6 GPa, respectively). The surface morphology, interfacial adherence, and bonding between the matrix-fiber phases in the composites were characterized using a scanning electron microscope (SEM).
