ジャーナル フリーWe have discussed the number of twists, the direction of it in a raw yarn and the direction of twist in pling the stretch yarn, to observe the necking phenomena of stretch yarns produced by the way of false twisting, and knew the following:
(1) Making the best stretch yarn of necking phenomena being least, it is necessary that the number of twists in a raw yarn is lower than that of pling twist, and the direction of twist in pling the stretch yarn being produced is inverse against that of the raw yarn.
(2) To make the best stretch yarn, the number of ply twist being in moment zero should be selected. It is also necessary that no trouble should be found in treating the stretch yarn.抄録全体を表示PDF形式でダウンロード (2531K) -

ジャーナル フリーThe paper describes some experimental results of frictional effects on the compression process of fibre assemblies.
(1) The external pressure required to compress the web-like assemblies is dependent on the mass of web per unit area, so that apparent compressibility K is decreased as mass of assemblies m is increased: K=K0(1-αm) where K0 is elastic compressibility, α is proportional constant given by friction. (see Fig. 5)
(2) When upper surface of assemblies, initial height of H0, is compressed by constant speed V0, the rate of inner layer compression V is deviated by the distance from surface (H0-H). Experimentally it is held that the relation between V/V0=ν and H/H0=h is 1-ν/h=a(l-h), where a is proportional constant depended on inter-fibre friction. (see Fig. 7)
(3) Experimental measurements made on the coefficient of withdrawal friction μ are found to conform reasonably well with the theoretical assumptions, so it may be concluded that parameters α and a are determined by inner frictional effect of compressed assemblies.

ジャーナル フリーA new technique for the differential staining of the skin-core structure of nylon yarn cross-sections is described. The technique is different from the method recently developed by W. R. Berry in that a single metal-complex dye, Lanasyn Grey BL (Sandoz), is used instead of a combination of two dyes, Kiton Pure Blue V, an acid dye, and Methyl Violet 2B Supra I, a basic dye. According to the staining and differentiation procedures applied one can obtain either the skin staining or the core staining in a highly reproducible manner.
It is evident that a distinct skin-core structure is present in nylon filament, both undrawn and drawn, and that the outer skin portion always permits the dye to enter and leave much more readily than the inner core portion.
A similar structure can also be revealed in “Tetoron” polyester fiber cross-sections. Disperse dyes were used to stain slide preparations with or without carrier, followed by washing with trichlorethylene. It was, however, difficult to get a sufficiently deep staining of the cross-sections, in particular of drawn yarns.抄録全体を表示PDF形式でダウンロード (3974K) -

ジャーナル フリーOn the previous paper, the new method by means of the infrared spectra had been developed for the study of the mechanism of celluose reaction. In the present report, the mechanism of the acetylation has been studied applying this new method with the birefringence and the X-ray diffraction method.
The following results were obtained:
1) On the infrared spectra method.
At the initial period on the acetylation, the accessibility of the hydroxyl group on the partially acetylated cellulose decreases. In spite of the proceeding of the acetylation, the spectrum-figures of the stretching mode which were originated in the unaccessible hydroxyl group on the partially acetylated cellulose are similar to the unreacted cellulose.
From these findings, it is considered that the acetylation has the selective reactivity on the amorphous region and the micro-heterogeneous property.
2) On the birefringence method.
The clear dual structure is observed on the cross-section of the partially acetylated film. From this finding, the macro-heterogeneous property for the acetylation is considered.
3) On the X-ray diffraction method.
At the initial period of the acetylation, the interferences of the partially acetylated cellulose are similar to the unreacted cellulose.
At the proceedings of the acetylation, the co-existence of the interferences which were originated in the unreacted cellulose and cellulose triacetate was observed. From these findings, the heterogeneous property of acetylation is considered.
On the basis of the above results, the mechamism of the acetylation is discussed.抄録全体を表示PDF形式でダウンロード (1835K) -
