ジャーナル フリーRelaxation modulus Er(t, ε) of polyethylene films measured at various temperatures from -20°C to near melting point under strain of 1_??_5% are expressed by following equations:
(1) Time-strain factorized model;
(2) Time-strain reduced model; In the above equations, the nonlinearized functions f(ε) and aε (ε) are approximated by where ε0 is the reduced strain. The αf; and αa represent the nonlinearity in the respective models. The nonlinearities of high density polyethylene are greater than those of low density polyethylene at any temperature. The αf and αa decrease with increasing temperature in the low temperature range, while they depend less on temperature in the high temperature range.
The αf and αa are analyzed by a composite model of crystalline and noncrystalline phase and a free volume theory, respectively. If the various assumptions are introduced in the analyses on the basis of molecular aspects, the above experimental results are interpreted qualitatively.
Master curves of the time-temperature superposition reduced to 20°C at each strain are obtained by the horizontal shift alone. The shift factor aT(T) is found to be independent on strain at each temperature. The evaluated apparent activation energies, however, are larger than those in references. Since this result can not be explained resonably, it would be still premature to conclude that the time-temperature superposition might hold in the nonlinear stress relaxation process.抄録全体を表示PDF形式でダウンロード (592K) -

ジャーナル フリーThe amorphous disulfide-crosslinked polycaprolactam fiber, a wool model fiber, was pretreated in 0.08 MKCN in a relaxed state for various periods at temperatures between 30 and 50°C, then, stretched to 100% in the same medium and the continuous stress relaxation, due to the cleavage of disulfide crosslinks, was measured. From the initial and the remanent stress values, the amounts of disulfide and monosulfide crosslinks and the intermediates at the end of the pretreatment in 0.08M KCN were estimated.抄録全体を表示PDF形式でダウンロード (424K) -

ジャーナル フリーA detailed UV and VIS spectral investigation of the interactions of sodium sulfanilic acid, methyl orange (MO), and butyl orange (BO) with two kinds of cationic polyelectrolytes (copolymer of methylhydroxyethyl-diallylammonium chloride and SO2 (PAS 1), copolymer of methylbenzyldiallylammonium chloride and SO2 (PAS 2)) has been carried out. No spectral change of sodium sulfanilic acid (1.0×10-4M) was found in the presence of PAS 1 solutions ranging from 1.0×10-5 to 1.0×10-2N in concentration. Addition of PAS (3-5×10-5N) to the dye solution (2-2.5×10-5M) resulted in the appearance of new absorption band. The new band was shorter wavelength region than that of free dye, and it might be considered as a result of aggregation of dye onto PAS chain. When largely excess amounts of PAS are present in the solution, MO binds monomolecularly onto PAS chain, but BO binds onto chain in aggregated form. The effects of the hydrophobic groups of the dyes and the polymers on the spectra are also discussed.抄録全体を表示PDF形式でダウンロード (581K) -

ジャーナル フリーThe following samples of polypropylene and polystyrene were prepared. Disperse dye (1, 4-diamino anthraquinone) was sandwiched between two films and hot-pressed, and then quenched (quenched film) or cooled gradually (annealed film). Quenched film was heat-treated at 150°C for 5 hr (heat-treated film). The dye desorption in boiling water for above samples was measured.
For polystyrene, the desorption rate was very low, and slightly differed by the dye content, the hotpressed temperature and the hot-pressed time. The crystallization of dye molecule was recognized by X-ray measurement for heat-treated film and annealed film, and the desorption rate of these films increased. For polypropylene, dye content available for desorption increased and the desorption rate decreased by increasing the hot-pressed time and the hot-pressed temperature. By annealing, the crystallinity measured by densitymethod increased and the desorption rate decreased. The value of the diffusion constant in desorption for polypropylene is 200 times larger than that for polystyrene, and is nearly half of that in absorption for polypropylene. Some discussion was made on these dye desorption behaviors.抄録全体を表示PDF形式でダウンロード (443K) -

ジャーナル フリーPolyester fabrics and filament were treated by heat transfer printing. The temperature rise of the fabrics during the treatment and the changes of mechanical properties of the fabrics and the fine structure of the filament due to the treatment were investigated.
The heat transfer printing was more effective for the temperature rise than the conventional heat treatment in hot air. In the case of the heat transfer printing, the time taken to reach a fixed temperature was about 20-30 sec. The thickness and the compressibility of the fabrics treated by the heat transfer printing decreased remarkably with the rise of the treating temperature. Also the stiffness increased by the treatment. The crystallinity and the crystallite size of the filament by the treatment were larger than those by the conventional heat setting.抄録全体を表示PDF形式でダウンロード (782K) -

ジャーナル フリーOn the fundamental characteristics of size detecting equipment of raw silk by using a photo-electric technique is discussed in this paper.
The thread runs through across the beam of light periodically by means of eccentricity guide roller and the cut off light is converted to the electric current by the photo cell. The electric current in the photo cell depends upon the amount of cut-off light influenced by the thickness of running thread.
The results were as follows:
1) The peak of output voltage was given at the slit width from 2 to 3 times as wide as against the thread thickness.
2) The output voltage increased with enlargement of input frequency up to 50HZ and it did not increase even the input frequency was enlarged. The output signal waveform was given essentially straight line more than input frequency 50 HZ.
3) The output voltage reached a constant when the reeling speed 100m/min and it did not increase even when the reeling speed increased. The output signal waveform was essentially straight line more than the reeling speed 100m/min.
4) Settling time became short as the reeling speed became fast.抄録全体を表示PDF形式でダウンロード (372K) -

ジャーナル フリーThe size of raw silk during the reeling process was measured with the detecting device built as trial by using a photo-electric technique.
By basic examing of size measurement of raw silk during the reeling process, the following results were obtained:
1) Relationship between the size and the output voltage was essentially straight line.
2) The detector could be measured slight size change of a cocoon filament continuously.
3) The size changes due to dropping end or feeding end of a cocoon filament can be detected by the proposed detector.
4) The oscillogram of measured size signal waveform and its time series which was calculated by means of weighing method show similar tendency.
5) The reappearance of size measurement by the proposed detector was observed.抄録全体を表示PDF形式でダウンロード (369K)
