After a polyvinyl alcohol filament was emerged from coagulating bath, it was drawn in wet state, in hot air, or in wet state and then in hot air. The maximum draw ratio and the maximum tenacity were obtained when the filament was drawn in hot air, or in wet state and then in hot air. The relation between tenacity ratio of drawn filament against the undrawn and the draw ratio is expressed by a straight line which passes through the original point, independent of the various drawing methods used. In filament which emerged from the coagulating bath at relatively lower velocity, the slope of the line is about 0.8. The relation between breaking tenacity and elongation is also expressed by a single curve independent of the drawing methods. As the emerging velocity is increased, tenacity at the same elongation and the maximum tenacity decrease.

The change of the hue by dyeing concentrations and the relation between the luminosity and the purity were studied through the chromatical diagrams (see diagrams a, b) on dyeing of cellulose acetate.It was shown through the measurement of the colour by means of the automatic colour difference meter that the purity of the colour increases first with the increased concentrations and then it decreases to darker shades after it reached the maximum, the most brilliant point. Most of dyes give the maximum purity at 1_??_2% dyeing concentration and some of them at the deep shade. The relation curves between the luminosity and the purity make a comparison of the brilliancy possible to the dyes with the same colours by criticizing their own positions in the graph.For the most of dyes, the rate of decrease in luminosity falls with increased concentration while the concentration does not reach over a certain range, and the hue tends to change in shade toward the left or right turn in the chromatical diagram as the concentration is increased.

(Tokyo Institute of Technology, Ookayama, Meguro-ku, Tokyo, Japan) The adsorption of monoazo acid dyes ranging various chemical constitution by 6-nylon has been examined quantitatively. In all cases of dye used the adsorption isotherm shows Langmuir type, the saturation value of dye adsorption is nearly equal to that of the amount of terminal amino endgroup of nylon fiber, and this value increases with the rising temperature. Electrostatic combination between dye acid and the site on fiber is dominant contribution in this case. The standard affinity of these dyes was calculated using Gilbert-Rideal equation. The relation between the standard affinity of dyes carrying two sulfonic acid group and the distance between sulfonic acid groups are explained by means of simple lattice model of dye site. It is suggested that for oxyazo dyes, the dyes carrying hydroxyl group not restricted by intra-molecular hydrogen bond formation, may be adsorbed by the fiber by means of hydrogen bond formation. In the series of substituted azo dyes (substituted aniline G acid), the increase of standard affinity corresponds to the increase in molecular weight, and the nature and position of the substituent is of minor importance, except in the case of solubilizing group and! hydrogen bond forming group.

(Tokyo Institute of Technology, Ookayama, Meguro-ku, Tokyo, Japan)定量研究了6-尼龙对不同化学成分的单偶氮酸性染料的吸附性能。染料的吸附等温线均表现为Langmuir型，染料的吸附饱和值与尼龙纤维末端氨基端基的吸附饱和值接近，且随温度的升高而增大。在这种情况下，染料酸与纤维上的位点的静电结合是主要的贡献。用Gilbert-Rideal方程计算了这些染料的标准亲和度。用染料位的简单晶格模型解释了带有两个磺酸基的染料的标准亲和力与磺酸基之间的距离的关系。对于氧偶氮染料，携带羟基的染料不受分子内氢键形成的限制，可能通过氢键形成被纤维吸附。在取代偶氮染料系列(取代苯胺G酸)中，标准亲和的增加对应于分子量的增加，取代基的性质和位置是次要的，除了溶解基团和!氢键形成基团。(1961年3月27日收到)
