ジャーナル フリーKroy-treated wool and dichlorocyanuric acid treated wool (DCCA-treated wool) were selected for wool fibers shrink-proofed with chlorine. The laundering treatment with domestic neutral detergent including non-ionic surfactant made the breaking strength and elongation decrease greatly for DCCA-treated wool at initial laundering treatment, but for Kroy-treated wool as well as intact wool, it made the elongation decrease gradually with increase of the laundering treatment times. After 5 times laundering treating each wool sample, the value of final elongation became almost equal in the value of the elongation of each wool sample which is pretreated with isopropanol (IPA) aqueous solution. The elongation of each wool sample which was pretreated with IPA aqueous solution hardly changed even if the laundering treatment times increased. These experiments showed that non-ionic surfactant including neutral detergent acted like IPA aqueous solution to wool fibers, and It was thought that the decrease of the breaking strength and elongation of wool by the laundering treatment with neutral detergent was dependent on the easiness of the extraction of the cell membrane complex (CMC) component of wool, which had been deteriorated by the each shrinkproof process with chlorine, by non-ionic surfactant.抄録全体を表示PDF形式でダウンロード (728K) -

ジャーナル フリーElectrospinning was carried out in an insulating liquid, Fluorinert FC-40 (Sumitomo 3M Ltd.), to judge whether "wet electrospinning" is practicable or not. Chloroform, N,N-dimethylformamide, and their mixture of 1 to 1 are used as a solvent of polystyrene. Among the three solvents of spinning solutions, only chloroform was fit for wet electrospinning in Fluorinert FC-40. Effect of polystyrene concentration was investigated using spinning solutions of chloroform solvent. Polystyrene particles and fibers were formed from the solutions of 5 to 15wt% polystyrene spinning solutions. From 20wt% solution, only fibers with many beads were formed, and from 25wt% solutions only fibers without beads were formed. The diameters of fibers formed were increasing with an increase in the concentration. The diameter was about 10um and 50um for fibers from 20wt% and 25wt% solutions, respectively. It is concluded that wet electrospinning is practicable. However, improvement of apparatus and process will be necessary to produce non-woven fabric of nanofibers.抄録全体を表示PDF形式でダウンロード (554K) -

ジャーナル フリーThe hybrid films of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) [P(3HBV)] and titanium tetraisopropoxide (TP) were prepared by using solvent-cast technique. P(3HBV) became stiff by the addition of TP (the Young's modulus increased from 1.09 GPa for pure P(3HBV) to 1.46 GPa for the hybrid containing TP 20wt%). The addition of TP inhibited the crystallization of P(3HBV). The bioactivity of the hybrids was evaluated by immersion into a simulated body fluid (SBF). The hybrids were bioactive as they induced the formation of calcium phosphate on the surface of the hybrids after immersion into SBF for 7 days. Furthermore, the addition of TP accelerated the alkali hydrolysis of P(3HBV). In contrast, the microbial degradation of the hybrids was slower than that of pure P(3HBV). It is likely that the microorganisms did not recognize as P(3HBV) in the hybrids because TP was dispersed in P(3HBV) matrix at a molecular level.抄録全体を表示PDF形式でダウンロード (730K)
