ジャーナル フリーSuppression of the deterioration of acidic bamboo paper by the Bookkeeper process (BK) and the dry ammonia ethylene oxide process (DAE) was investigated. These deacidification processes reduce the acidity of both acidic bamboo and hardwood papers to pH 8, which is comparable to acid-free paper. Deacidified bamboo and hardwood papers had higher pHs than untreated papers after accelerated aging for one week at 100 °Cin a sealed tube. Both deacidification processes preserved the mechanical properties (e.g., folding endurance and zero-span tensile strength) of bamboo papers after one week of sealed tube aging. In contrast, bamboo papers deacidified by BK and DAE processes exhibited a significance loss in tearing strength after one week of tube aging, compared with deacidified hardwood papers. The reduction in the tearing strength of deacidified bamboo papers depended considerably on the reduction in the degree of polymerization during sealed tube aging. Due to the rapid reduction rate of degree of polymerization during sealed tube aging for one week of bamboo papers deacidified by DAE process, such paper exhibited appreciably higher degradation rates than bamboo papers deacidified by the BK process.抄録全体を表示PDF形式でダウンロード (559K) -

ジャーナル フリーThis paper attempts to propose a laundry use of spent bathwater in Japan sterilized by non-diaphragm electrolytic treatment (Single cell). Twenty liters of spent bathwater was treated with 25 mL of electrolyzed water obtained by electrolytic treatment to examine its bactericidal effect. The treated bathwater also was used for washing fabrics to examine the antibacterial effect of the treatment on the washed fabrics. Before the experiment, non-treated bathwater was used for washing fabrics and revealed that the washed fabrics had as many as 8.19×103 CFU/mL viable bacteria. When distilled water was used for “rinsing” the washed fabrics, many viable bacteria remained on the washed fabrics, even after “rinsing” for 12 minutes. Addition of 25 mL of aqueous HCl to 20 L of spent bathwater indicated that the acid did not have any bactericidal effect. In contrast, addition of 25 mL of electrolyzed aqueous HCl to 20 L of spent bathwater almost completely eliminated viable bacteria. Moreover, when the treated bathwater was used for washing fabrics dipped in the spent bathwater, few viable bacteria were found on the washed fabrics. These results demonstrate that non-diaphragm electrolytic treatment was very effective at killing bacteria in spent bathwater and at sterilizing fabrics washed in the treated bathwater.抄録全体を表示PDF形式でダウンロード (1517K) -

ジャーナル フリーThis study was conducted to develop a method for reusing of spent bathwater in Japan which was disinfected by weakly acidic electrolytic treatment. Electrolyzed water obtained from electrolytic treatment without a diaphragm (single cell) was diluted with spent bathwater and used to launder fabrics. The spent bathwater did not remove dirt from the fabrics well, but it effectively sterilized the washed fabrics. The detergent efficiency was found to decrease by about 5% when spent bathwater was used when compared to non-treated spent bathwater. The decreased detergent efficiency was believed to be caused by reduced foaming and affinity. To obtain a sufficient sterilization effect without decreasing detergent efficiency, untreated spent bathwater was used for washing, after which spent bathwater mixed with electrolyzed water was used for rinsing. Even when rinse times as short as one cycle for 3 min were used, this method led to sufficient sterilization of fabrics for laundry. Additionally, odor testing using an odor concentration meter and evaluation by a monitor panel showed that electrolytic treatment markedly decreased the odor level of the test fabrics. Overall, these findings indicated that bacteria on fabrics could be effectively attenuated with no decrease in detergent efficiency if electrolyzed water diluted with spent bathwater was used for rinsing after washing with untreated spent bathwater.抄録全体を表示PDF形式でダウンロード (1442K) -

ジャーナル フリーThe inhomogeneous compressive strain behavior of the friction material was analyzed by means of digital image correlation method (DICM). Macroscopic strain of the sample without a cashew decreased monotonically with the increasing molding pressure, and DICM analysis indicated homogeneous strain distribution. While sample containing cashew showed a peculiar molding pressure dependence in macroscopic strain, which the strain increased remarkably above 30 MPa. The result of DCIM analysis indicated that the void structure introduced by the spring-back periphery of cashew caused the inhomogeneous strain distribution as well as larger deformation upon the compressive load. It was also found that the addition of cashew and mica greatly enhanced the void formation.抄録全体を表示PDF形式でダウンロード (3333K) -

ジャーナル フリーA biodegradable composite consisting of poly(butylene succinate) (PBS) matrix and polyvinyl alcohol (PVA) binder-reinforced silk/bamboo paper was prepared by hot compression molding, in order to make more effective use of waste silk resources. The use of PVA binder enhanced the mechanical properties of both silk/bamboo paper and silk/bamboo/PBS composite for a range of binder contents. These enhanced properties were studied in detail, and results indicated that with increased PVA binder content, the tensile strength, tensile modulus, and elongation of the hybrid papers increased. PVA binder-improved silk/bamboo paper was better able to reinforce PBS composite compared to paper with zero binder content. The tensile and flexural properties of this green composite were improved remarkably, although impact resistance was degraded to some extent.抄録全体を表示PDF形式でダウンロード (1548K)
