ジャーナル フリーThe P. V. C fibers containing dinitronaphthaline (DNN) are manufactured by dry spinning of P. V. C solution in acetone and CS2, and the fibers are drawn up to 400% elongation at 100°C.
The stress-strain curves of PVC-DNN fibers thus obtained are measured by Instron tensile tester. From these results, it is found that the strength and elastic properties of P. V. C fibers containing 5-10% DNN are larger than those of pure P. V. C fibers but the elongation of P. V. C fibers containing 5-10% DNN are smaller than those of pure P. V. C fibers.
These properties of DNN contained in P. V. C fibers are maintained in the remarkably wide range of temperature, but at about 100°C, the deformation and shrinkage of P. V. C fibers are smallar than those of DNN containing fibers whose permanent deformations are however comparable with the P. V. C fibers.抄録全体を表示PDF形式でダウンロード (257K) -

ジャーナル フリーThe swellings of P. V. C. films having thermal bridging are measured in acetone, methyl ethyl ketone, methyl isobutyl ketone, acetophenone, cyclohexanone, tetrahydrofuran and the mixtures of these ketones and CS2. From these results, the parameters of the polymer-solvent interaction μ are calculated and the minimum values of μ are found by adding CS2 in acetone, methylethyl ketone, methylisobutyl ketone and acetophenone, but the small μ's values are increased by adding CS2 in cyclohexanone and tetrahydrofuran solutions.
The viscosities of the dilute solution of P. V. C. in methylisobutyl ketone, acetophenone and cyclohexanone are measured. From these results the values of _??_η_??_ and k′ (in Huggin's equation _??_ )are calculated. In comparing the _??_η_??_, k′ and μ, it is obvious that _??_η_??_ of cyclohexanone solution is larger than _??_η_??_ of acetone, methyl ethyl ketone, methyl isobutyl ketone and acetophenone solution, k′ and μ of cyclohexanone solution are smaller than those of the ketone solutions, and those of methylisobutyl ketone and acetophenone solution are almost the same.抄録全体を表示PDF形式でダウンロード (280K) -

ジャーナル フリーIsotropic cellulose-xanthate filament shrinks on regeneration and drying after regeneration, while extended filament shows diminished shrinkage on the same conditions. The degree of swelling of xanthate filament decreases with the degree of extension. There is similar relationship for the freshly regenerated cellulose filament which is pre-extended in the xanthate state. The anisotropy of swelling of xanthate filament increases with extension and the filament shows almost the same value after regeneration. These effects are more remarkable in NH4-xanthate than in Zn-xanthate. Degree of swelling of cellulose filament regenerated from Zn-xanthate is lower than that from NH4-xanthate.抄録全体を表示PDF形式でダウンロード (268K) -

ジャーナル フリーIn the preceeding paper, we have investigated the relation between heterogeneous structure of cross section of P. V. A. filament and spinning condition by the use of microscope and electron-microscope. Model sample in which skin and core parts can be observed seperately was prepared, in order to observe the detailed properties of both parts.
It was concluded that the main factor for the skin formation was the pressure of water which diffused by osmosis in the coagulation process, since both optical and swelling anisotropies were observed in the gel which was formed by the coagulation under no external force. The difference of adsorption abilities between the skin and core parts was also estimated measuring the diffusion process of iodine and dye through both parts.抄録全体を表示PDF形式でダウンロード (1963K) -

ジャーナル フリーIn the first report of this study the authors described that the scale ends of an Angora rabbit fur are like the obliquely cut ends of pipes and their apexes point always to the outside of the curved portion of the crimped fur (this is now called O-I type). But it is reported by others that on a wool fibre the apexes of the scales point inside of the crimp, i.e., the behavior is opposite to the Angora-rabbit fur (M-Y type).
It was at first thought that this opposite behavior was caused by the different morphological constructions of the two types of the fibres because their chemical compositions are not remarkably different. The medulla may be a cause of the great difference of the morphological construction, so a cat fur was investigated, which has a similar type -discontinuous- medulla as the rabbit fur does. But the result is negative and its scale showed a middle type and they were neither of O-I type nor of M-Y type.
The observations on the other animal fibres showed that a Cashmere hairs have a middle type, whilst the Mohair's and Camel's are of O-I type.
A geometrical explanation was given for the conditions under which two types of scales may appear.抄録全体を表示PDF形式でダウンロード (1568K) -

ジャーナル フリーBy measuring the swelling of samples in glacial acetic acid, the cornification of cellulose and the reactivation of the cornified cellulose were investigated, and the results obtained are as follows.
(1) In the dehydrating course of drying, the cornification develops increasingly after the water content has fallen below 50% in the case of native cellulose or below 80% in the case of cellulose treated with 10% NaOH beforehand.
(2) The cornification is appreciably inhibited by drying after replacing water with organic liquid, and the smaller the surface tension, affinity to hydroxyl group, and the polarity of the liquid, the greater the preventing action of the liquid.
(3) If the cellulose not cornified in drying is placed in the room of moderate humidity, the cornification takes place markedly during storage.
(4) The cornified cellulose is reactivated by treating it with proper liquid; the greater the cohesive energy density of the liquid, the higher the activity as reviving reagent. Acetic acid displays its reviving action only at moderately higher temperature.
(5) Mechanical grinding is exceedingly effective in the reactivation of the cornified cellulose.抄録全体を表示PDF形式でダウンロード (469K) -

ジャーナル フリーIn the previous paper, the general visco-elastic behavior of textile materials which were extented by the sinusoidal rate of extension under low frequency (period 60_??_200 sec.) and large amplitude (7.44%) were discussed. Using the same method and same apparatus as described in Part 1 of this series, the effects of amplitude on the cyclic stress-strain curves were studied. The amplitudes used in this report were 1.87, 3.18, 7.44, 11.30 and 15.20%.
From the experimental data, the following conclusions were deduced.
(1) The stress-strain curves for sinusoidal extension rate were not represented by a single model as Voigt or Maxwell under large amplitude, but they approached to single model under small amplitude.
(2) The stress-strain curves for extension were more complex than for retraction under large deformation.
(3) Small elongation was due to visco-elasticity but mainly due to plasticity for wool, acetate rayon, viscose rayon and tire cord rayon.抄録全体を表示PDF形式でダウンロード (246K) -

ジャーナル フリーA particularly simple example of application of the double elasticity theory was previously discussed in this paper. In this example, the rigid bar-like fibers are oriented in parallel to the long axis of fiber bundle. Assuming the centres of fiber are slipped over one another with no change of apparent density of bundle, the typical formulas of stress-strain relations, load-elongation curves, extreme strength and hysteresis of repeated loading are presented. And the effects of such factors as fiber length, grasped distance of sliver, number of fibers in cross section of sliver, fiber modulus of elasticity and interfiber coefficient of friction on them have been determined respectively.抄録全体を表示PDF形式でダウンロード (388K) -

ジャーナル フリーA special press was prepared in order to study on the crabbing and the pressing of the woolen fabrics. It has the pressing surface of 15×15cm2 and is devised so that a sample fabric or fabrics can be pressed under the pressures of various intensities at the required temperatures. The fabrics can be treated under the wet or dried states, the former being corresponding to a crabbing and the latter to a pressing process in the factory.
The setting effect of these treatments is appraised by observing the permanency of their lustres of the fabrics treated.抄録全体を表示PDF形式でダウンロード (2099K) -

ジャーナル フリーThe crease recovery measurements were made on fabrics at time intervals from 2 to 90 min. after release of the weight with the Monsanto type crease recvery tester. When the logarithm of percent crease recovery was plotted versus the logarithm of time of recovery in minutes, straight lines were obtained in all cases with these plots at the time intervals from 2 to 10 min. It is found, therefore, that at this early period the data can be represented by the following equation;
y=y1tm
where t is the time of recovery in min., that is the time after release of the weight, y is the percent crease recovery at time t and y1 is the extrapolated value of y at t=1. The parameter, m, indicates whether the fabric opens rapidly or slowly. The value of y at the final recovery was obtained by the extrapolation from the experimental data during early 10min., and the parameter, m, was discussed in further detail.抄録全体を表示PDF形式でダウンロード (345K) -
