An elastic influence of a viscoelastic liquid on the slow flow into a slit has numerically been investigated for the Maxwell model by the perturbation method. And, over 0.05 in Weissenberg number, the main stream line becomes concave from below, such as the stem of wine-glass, and the circulating flow becomes large; This flow pattern is that of the melted polymer. In addition, numerical values of shear stress and normal stress difference show a similar tendency to the experimental results.
From this fact, the numerical perturbation method will be effective to analyze the melted polymer flows.

There are many types of rubber-covered pressure rollers which provide nip uniformity by making the load distribution of a mangle uniform. In this paper, four types of rubber-covered pressure rollers are dealt with analytically. The first one is the pressure rollers supported at their central zone. The second one is a combination of a pressure roller mentioned above and a conventional roller supported at both ends. The third one is the so-called aqua-roller. The last one is rubbercovered rollers with a cambered covering, or with a cambered mandrel.
Flexural behavior of these four types of rubber-covered pressure rollers is analysed using the mathematical theory derived in an earier paper. The following are conclusions obtained from the analytical investigations :
(1) The shape of the mandrel of rubber-covered pressure rollers providing a mangle with a uniform load distribution are found to be independent of the size and the elasticity of the rubber covering.
(2) Some factors of the mandrel shape must be determined with a sufficient accuracy.Otherwise, uniformity of load distribution is degraded considerably.
(3) The uniformity indexes of load distribution of four types of pressure rollers discussed in this paper and two types of covered rollers previously analysed by the authors are compared.They are listed below in a descending order of the uniformity index :
1) Rubber-covered rollers with a cambered covering or with a cambered mandrel,
2) an aqua-roller and a conventional covered pressure roller pressed together,
3) pressure rollers supported intermediately,
4) pressure rollers supported at the central zone,
5) moment compensation pressure rollers, and
6) a combination of pressure rollers of different supporting positions.
(4) There exist an amount and a shape of the surface camber of coverings and mandrels which provide a mangle with a rigorously uniform load distribution for any combination of rubbercovered pressure rollers.

To use the CCM system in a dyeing house, a wide variety of dyeing conditions are more important than the color prediction logic for calculation of the color matching. This article deals with dyeing conditions required for the actual use of CCM system in a dyeing house.
This report consists of the following four parts: (1) Precision of a spectro-photometer, (2) Accuracy of dyeing operation, (3) How to cotrol dyeing factors, and (4) How to use CCM system. Two basic conditions are indispensable for the practical and effective CCM system. One is whether various characteristic conditions in a dyeing house are taken into consideration for the CCM software. And another is whether a dyeing house itself is well controlled and fully arranged for application of the CCM system.

Fifteen kinds of fabrics were investigated by a series of tactile, visual and burning tests to identify their constituent fibers. The present investigation aims to make differences clear of identifying ability of three groups of subjects, i.e., college students, homemakers and women clericals. A hierarchical cluster analysis and a nonmetric multi-dimensional scaling analysis were applied to illustrate three kinds of confusion matrices, and to compare subject groups each other.
Main results are (1) Identifying ability of students in the school of textile and clothing are higher than those of homemakers and women clericals, and (2) Identification of synthetic fibers are more difficult than that of natural fibers.
