ジャーナル フリーThe present authors have estimated the bleach-degrees of the unbleached chemical wood pulps by the authors' method. From the analytical data gained in the bleach-degree estimations a following conclusion was obtained:
The chlorinations of the unbleached pulps always require two or three stages. And the mean figure of the “Honda's Values”, i.e. the chlorine requirements for the bleaching of the pulps is equall to (Roe's Value) × 1.60 ± 0.03.
Furthermore, the mechanism of the chemical reactions in the bleach-degree estimations is explained by the present authors' method.抄録全体を表示PDF形式でダウンロード (399K) -

ジャーナル フリーThe mechanical conditions of mule directly related to spinning are the length L of spinning field. the delivery-length F of sliver from front roller and the revolutions N of spindle, which are recorded against the elapsed time t. The spinning-length L is different from the horizontal displacement l of spindle or carriage near the front roller, but almost equal to it in the later, effective part of spinning. The length l or L is generally represented as follows: The terms F and N may also be shown in the similar type of formula as l(t), and are also the functions of position l, say; The terms except l. L, F and N are constant, and sometimes are regarded as b=k=β=1 or τ=κ=0 in the above equations. The displacement and also the delivery are more or less deformed from the shape of scroll because of the inertia of carriage, especially at the beginning of outward-run. At first the carriage-movement is delayed and then accelerated. The delivery is less deformed than the displacement. Mule has several discontinuos points of motions in its spinning process. The spindle-revolutions transit smoothly in the oil-box driving system employed in this experiment.抄録全体を表示PDF形式でダウンロード (432K) -

ジャーナル フリーThe effect of the catalyst on the pH change of urea formaldehyde precondensate solution by heating, and the washing fastness of resin and the crease resistancy of the treated fabric were studied and obtained the following results. From the effect on the pH change, the catalysts are classified to the following four types, i.e., (1) With the use of this type catalyst, the pH of the precondensate solution rises remarkably along with the elapsed times of the heating. Hydrochloric acid belong to this type. It decomposes dimethylol urea and ammonium chloride is formed by heating. The pH change described above is due to this reaction. For this reason, when hydrochloric acid is employed as the catalyst for the crease resistant finish, the treated effect has an inferior washing fastness due to the retarding of the hardening of resin. (2) This type catalyst diminishes the pH of the solution by heating. The latent catalyst, for example, picoline-monochlor acetic acid belong to this type. The catalyst of this type has good effect on the hardening of resin, so it gives an excellent washing fastness and the crease resistancy to the treated fabric. (3) This type catalyst has the intermediate property and treated effect of type 1 and 2. Aluminium chloride belongs to this type. (4) With the use of this type catalyst, the pH of the solution diminishes but after passing through the minimum pH value, it rises rapidly. Ammonium salts of inorganic acid belong to this type. In an acq. solution, ammonium salts hydrolyse and dimethylol urea is decomposed to the urea and formaldehyde. Thus formed ammonium hydroxide and formaldehyde react imediately and inorganic acid is liberated. When the concentration of acid increases steadily by this reaction, dimethylol urea is decomposed and the pH of the solution rises rapidly. For these reasons, the excellent latent catalyst and ammonium salt of inorganic acid have the optimium amount to be employed to the solution of dimethylol urea.
The effect of the catalyst for the crease resistancy of the treated fabric is not remarkable.抄録全体を表示PDF形式でダウンロード (443K) -
