Influence of alkali treatment on internal microstructure and tensile properties of abaca fibers

The objective of this study is to investigate the effect of alkali treatment on the internal microstructure and tensile properties of abaca fibers. The abaca fibers were immersed in aqueous solutions of NaOH (5, 10, or 15 wt%) for 30 min, rinsed and dried. The fibers were subsequently characterized by scanning electron microscopy, X-ray diffraction (XRD), Fourier transform-infrared spectroscopy (FT-IR), and tensile strength tests. The lumen is a hollow region in each elementary fiber of the abaca fiber bundles. It was found that the lumen of the abaca fibers completely collapsed after 10 and 15 wt% NaOH treatment, due to swelling of the fibers. The fibers also became twisted after these alkali treatments. It was found that cellulose I in abaca fibers was partially transformed to cellulose II after 15 wt% NaOH treatment, as evidenced by XRD measurements. FT-IR analysis indicated that the alkali treatment led to a gradual removal of binding materials; such as hemicelluloses and lignin, from the abaca fibers, resulting in the separation of abaca fiber bundles into individual elementary fibers. The tensile strength of alkali-treated abaca fibers did not vary with alkali concentration. The Young's modulus of the abaca fibers treated with 5 wt% NaOH solution increased by 41%, whereas those treated with 10 and 15 wt% NaOH solution decreased by 24 and 29%, respectively. A non-linear behavior was observed in the stress strain curves of the abaca fibers after 10 and 15 wt% alkali treatment, which could be attributable to the twisting of the fibers.

アバカ繊維の内部構造と引張特性に及ぼすアルカリ処理の影響について調査した．繊維中のルーメンは10,15wt%NaOHで処理すると消失すると共に繊維がツイストすることを見いだした．アルカリ処理したアバカ繊維の引張強度にはほとんど変化はない．しかし，5wt%NaOHで処理した場合，ヤング率は41%増加するのに対して，10,15wt%NaOHで処理するとそれぞれ24%，29%低下する．10,15wt%NaOHで処理したアバカ繊維は非線形の応力-ひずみ関係になり，この非線形性は繊維のツイスト化によってもたらされると推察される．

Fiber-content dependency of the optical transparency and thermal expansion of bacterial nanofiber reinforced composites

We produced transparent nanocomposite reinforced with bacterial cellulose having a wide range of fiber contents, from 7.4 to 66.1 wt %, by the combination of heat drying and organic solvent exchange methods. The addition of only 7.4 wt % of bacterial cellulose nanofibers, which deteriorated light transmittance by only 2.4%, was able to reduce the coefficient of thermal expansion of acrylic resin from 86×10–6 to 38×10–6 K–1. As such, the nanofiber network of bacterial cellulose has an extraordinary potential as a reinforcement to obtain optically transparent and low thermal expansion materials.


Optically transparent bionanofiber composites with low sensitivity to refractive index of the polymer matrix

Transparent polymers were reinforced by bacterial cellulose (BC) nanofibers, which are 10×50 nm ribbon-shaped fibers. They exhibited high luminous transmittance at a fiber content as high as 60 wt %, and low sensitivity to a variety of refractive indices of matrix resins. Due to the nanofiber size effect, high transparency was obtained against a wider distribution of refractive index of resins from 1.492 to 1.636 at 20 °C. The optical transparency was also surprisingly insensitive to temperature increases up to 80 °C. As such, BC nanofibers appear to be viable candidates for optically transparent reinforcement.
