TL;DR: In this article, the surface properties of cellulose fibers have been modified by heat treatment, by silane coupling agents, and by maleated polypropylene grafts, which yielded information on the fibers' acid/base interaction potential.
Abstract: The surface properties of cellulose fibers have been modified by heat treatment, by silane coupling agents, and by maleated polypropylene grafts. The effectiveness of these methods has been evaluated by electron spectroscopy (ESCA), by contact angle measurements, and by inverse gas chromatography. The latter analyses yielded information on the fibers' acid/base interaction potential. Cellulose was found to be amphoteric, with prevalent acidic properties. Heat and chloro-silane treatments accentuated acidity, while amino-silane treatment produced net basicity in the fiber surface. Modification with maleated polypropylene reduced specific interactions and converted the fiber to a predominantly dispersion-force solid. The modified fibers were used in composites with polypropylene (neutral), polystyrene (base), and chlorinated polyethylene (acid) as matrix. Stress/strain and dynamic mechanical parameters were found to vary with acid/base interactions between polymer and fiber, significant improvements being noted in elastic and storage moduli, in tensile strength and elongation. In polypropylene, properties were unaffected by acid/base considerations. Acid/base forces, not necessarily dominant, merit consideration in the design of surface modification strategies intended to optimize composite mechanical properties.

TL;DR: Oil sorption capacities of various natural and man‐made fibrous sorbents were compared in a simulated seawater bath containing oil and no definite advantages were observed using man-made bicomponent and biconstituent fibers over regular man‐ made fibers with respect to their sorption capacity.
Abstract: Oil sorption capacities of various natural and man-made fibrous sorbents were compared in a simulated seawater bath containing oil. Natural sorbents such as milkweed, kapok, cotton, and wool showed higher sorption capacities than man-made sorbents such as polyester, polypropylene, viscose rayon, nylon 6, nylon 66, and acetate. Sorption capacities of the natural sorbents were over 30 g oil/g fiber. No definite advantages were observed using man-made bicomponent and biconstituent fibers over regular man-made fibers with respect to their sorption capacity. Analyses of sorption mechanisms using an environmental scanning electron microscope revealed that an oil deposit disappeared from the fiber surface after a certain time interval in milkweed, kapok, and cotton. This suggested that the sorption of oil in these fibers occurred through capillary action, probably due to their hollow lumens. Contrarily, adsorption, a surface phenomenon, would be the most prominent mechanism for oil sorption of wool fibers due to large amounts of surface wax, irregular scaly surfaces, and crimp. Effects of both adsorption and absorption were shown in the oil sorption of man-made fibers, depending upon the type and shape of the sorbent. Dumbbell-like oil deposits were seen on the fiber surface in certain oleophilic man-made fibers, because of a partial wetting of oil on the fiber surface. For some hydrophilic man-made fibers such as polyvinylalcohol and copolymer of isobutylene-maleic anhydride, the physical configuration of the fiber was a decisive factor in determining oil sorpton capacity of the sorbents. © 1993 Wiley-Liss, Inc.

TL;DR: In this article, the dynamic mechanical properties of low density polyethylene filled with isocyanate treated and untreated short sisal fiber composites were studied as a function of temperature and frequency.
Abstract: The dynamic mechanical properties of low density polyethylene filled with isocyanate treated and untreated short sisal fiber composites were studied as a function of temperature and frequency. By the incorporation of short sisal fiber into LDPE, the stor age moduli (E') and loss moduli (E") increase, whereas the mechanical loss factor decreases. The effects of fiber-matrix adhesion on the viscoelastic properties of the com posites have been studied and it has been found that the increase in adhesion increases the storage modulus. The effects of fiber length, fiber orientation, and fiber loading on the dynamic mechanical properties have also been investigated. In all cases, storage moduli (E') and loss moduli (E") decrease with temperature and increase with fiber loading.

TL;DR: In this paper, surface-coated fibers with butyl benzyl phthalate (BBP)-plasticized PVC were evaluated as a reinforcement in thermoplastic matrices.
Abstract: Cellulose fibers surface-coated with butyl benzyl phthalate (BBP)-plasticized PVC were evaluated as a reinforcement in thermoplastic matrices. Coated fibers were agglomerated during compounding with polypropylene (PP) and polyethylene (PE). However, an excellent dispersion and improved processability were achieved in polystyrene (PS). Melt rheology was also seen to be affected by fiber coating, and viscosity was lower for coated fibers. Fiber coatings seem to lubricate the blending process as well as to protect fiber from damage during processing. Fiber length was unaffected during treatment when coated fibers were used, as shown by microscopic investigation of extracted fibers, whereas the length of untreated fibers was reduced during processing. Introducing surface-coated fibers into PS resulted in an increased elongation at break and improved impact strength of composites. The pullout of the fibers is suggested to be responsible for both improvements. The interphase achieved in PS with PVC/BBP-coated fibers was simulated with PS/PVC/BBP blends. From DSC and DMTA, it was shown that BBP is a cosolvent for PS and PVC and that a single-phase material was achieved at the relevant concentrations, which also was confirmed by optical clarity. © 1993 John Wiley & Sons, Inc.

TL;DR: In this article, a thermoplastic composites reinforced with wheat straw fibers were prepared, and FTIR measurements revealed some PHB/straw fiber molecular interactions that interfere with the PHB crystallization.
Abstract: Biodegradable thermoplastic composites reinforced with wheat straw fibers were prepared. The matrix was an expensive polyester, poly-3-hydroxy-butyrate (PHB), produced by bacterial fermentation. Before being mixed with the PHB, the wheat straw fibers were subjected to a steam explosion process that induces morphological and structural changes in lignocellulosics. Such changes enhance the interaction with the thermoplastic matrix. The two components were melt mixed and the composite molded under hot compression. Compared with neat PHB, not only does the composite material show better mechanical properties but, moreover, production costs are dramatically reduced because wheat straw is a very inexpensive product. Finally, FTIR measurements revealed some PHB/straw fiber molecular interactions that interfere with the PHB crystallization. © 1993 John Wiley & Sons, Inc.

TL;DR: In this article, the effect of metal ions on the tensile properties of chitosan fibers was studied and it was found that after chelation of metal ion the chitosa fibers gained substantial increases in both dry and wet strengths.
Abstract: Chitosan fibers were treated with aqueous solutions of CuSO4 and ZnSO4 for different periods of time to prepare samples containing different levels of metal-ion contents. The effect of metal ions on the tensile properties of chitosan fibers was studied. It was found that after chelation of metal ions the chitosan fibers gained substantial increases in both dry and wet strengths. The metal ions were readily removed from the chitosan fibers by treatment with an aqueous EDTA solution. The effect of the degree of acetylation on the chelating ability of the chitosan fibers was also studied. It was found that after acetylation the chitosan fibers lost the chelating ability due to the conversion of primary amine groups to acetamide groups. © 1993 John Wiley & Sons, Inc.

TL;DR: The role of boron compounds on the flame retardance characteristics of unmodified as well as surface modified wood fiber-filled polypropylene composites is discussed in this paper.
Abstract: The role of boron compounds on the flame retardance characteristics of unmodified as well as surface-modified wood fiber-filled polypropylene composites is discussed. The effect of three different additives, m-phenylene bismaleimide (BMI), BMI-modified polypropylene (BPP), and a mixture of borax and boric acid, on the mechanical properties of various cellulosic fiber-filled polypropylene composites was also investigated. BPP showed the greatest effect on composite strength. The combination of BPP with a 35/65 (weight ratio) explosion fiber/polymer resulted in a composite with greater tensile strength in comparison with virgin polypropylene. Although the addition of BMI to the filled composite marginally decreases the strength of the virgin polymer, the performance of these modified composites is much better compared with that of unmodified ones. Overall, these findings indicate that BPP and BMI impart some degree of interaction between the cellulosic filler and polypropylene, particularly in the interfaci...

TL;DR: In this article, the chemical composition and physical properties of G. rufobrunnae silk fibroin have been studied, which contains a large amount of glycine and alanine, as well as hydroxyl, acidic, and basic amino acids.
Abstract: Chemical composition and physical properties of silk fibers from Gonometa rufobrunnae, a silkworm belonging to the family Lasiocampidae (order Lepidoptera, class Insecta) have been studied. G. rufobrunnae silk fibroin contains a large amount of glycine and alanine, as well as hydroxyl, acidic, and basic amino acids. The gly/ala ratio is 1.5, similar to that of Bombyx mori silk fibroin. The ratio between polar and nonpolar amino acids is higher than that of either domestic (family Bombycidae) or wild (family Saturniidae) silk fibroins. The sericin is characterized by a large amount of hydroxyl amino acids, mainly serine. The infrared spectrum of G. rufobrunnae silk fibroin showed characteristic absorptions at 1630, 1530, and 700 cm−1 attributed to the β structure and at 1650 and 1540 cm−1 due to the random-coil conformation. The birefringence and isotropic refractive index values were 0.027 and 1.559, respectively. The differential scanning calorimetry (DSC) curve showed two minor endothermic peaks at 222 and 288°C, together with a major endothermic peak at 344°C, attributed to the decomposition of the fibroin with β conformation. The fibers exhibited a maximum contraction peak (4.3%) at about 230°C. The dynamic storage modulus (E′) exhibited an abrupt drop at 190°C, while the loss modulus (E″) curve increased above 185°C with a sharp slope. The surface of degummed G. rufobrunnae silk fibers was very smooth. The shape of the cross section was triangular, round, or roundish shaped. Some fibers were very flat, showing a ribbonlike shape. © 1993 John Wiley & Sons, Inc.

TL;DR: In this paper, the phase structures of unswollen domains and swollen rubber were considered to originate from different structural components characteristic of α-keratin, namely, the high-sulfur matrix and the low-Sulfur microfibrils being randomized by swelling.
Abstract: Various α-keratin fibers that had been treated with an 11M LiBr solution containing N-ethylmaleimide showed typical rubberlike elasticity in a solution composed of equal volumes of 8M LiBr and diethylene glycol mono-n-butyl ether. Stress—strain relations of the swollen fibers were treated with a two-phase model: a mechanically stable phase of higher cross-linked domains and a rubber phase with lower cross-link density. Stress—strain curves for a variety of keratins (three different human hairs, six different wools, mohair, cashmere, llama, alpaca, angora, and opossum) were analyzed by applying non-Gaussian chain statistics to the swollen keratin network, including microdomains, which act as reinforcing filler particles in rubber. The phase structures of unswollen domains and swollen rubber were considered to originate from different structural components characteristic of α-keratin, namely, the high-sulfur matrix and the low-sulfur microfibrils being randomized by swelling. It has been suggested that (1) the modulus of swollen fibers increases with increase of the content of disulfide (SS) in keratins, (2) the volume fraction of high-sulfur domains increases with increase of SS content, and (3) the number of intermolecular cross-links in the rubber region of low-sulfur proteins is virtually the same among keratins and reaches about 65–75% of the SS linkages in the corresponding proteins. Some discussion has been made on the SS bonding in situ, namely, SS linkages between the low-sulfur proteins, between the low-sulfur and the high-sulfur proteins, and between the high-sulfur proteins in keratins. © 1993 John Wiley & Sons, Inc.

TL;DR: In this paper, a tradeoff in solubility and fiber properties was noted as the butyryl acetyl ratio decreased, which resulted in lower fiber modulus and strength.
Abstract: Fibers were spun from isotropic and anisotropic DMAc solutions of cellulose esters. Take-up speeds of the dry jet/wet spinning process varied. Water served as the coagulant. The mechanical properties of the fibers increased as spinning progressed from the isotropic to the anisotropic state of the solution. A trade-off in solubility and fiber properties was noted as the butyryl acetyl ratio decreased. Whereas high butyryl content enhances both overall solubility and the formation of liquid-crystalline solutions at lower concentration, it results in lower fiber modulus and strength
