Ordinary woven fabrics (bi-axial fabrics) are composed of warps and fillings, and their modulus of elasticity and tensile resistance in bias direction are lower as compared with those in warp and filling directions. In order to improve these characteristics, new “Tetra-axial Woven Fabrics” composed of warps, fillings and bias yarns were made and assessment was performed on the physical properties of fabrics. To clarify the effect of difference in the structure between bi-axial and tetra-axial fabrics in load-elongation curves and tensile resistances, the moduli of elasticity and tearing strengths were investigated, based on the technique by F. L. Scardino and F. K. Ko.
Tensile resistance and modulus of elasticity of bi-axial fabrics are low in bias direction. But for tetra-axial fabrics, the dependence of tensile strength on direction is very small. The tearing strength of tetra-axial fabrics is very larger than that of bi-axial fabrics.

Using a corneal reflection system consisting of an eye-mark recorder, were measured eye-movement, fixation time at a point and its frequency distribution and vector direction of eye-movements of experts and non-experts when inspecting fabrics moving on a plate or stopped on it. It was discussed what parts of the fabric were observed by inspectors, and how they recognized the part visually as fabric defects.
The results obtained are as follows. (1)When experts and non-experts inspect fabrics, their eye-movements are composed of the saccadic movement moving rapidly and the eye fixation at some characteristic parts of the fabric. When the fabric is moving at low speed, all experts and non-experts evaluate both sides of the fabric which may have valuable information. (2)The mean fixation time at one point on the fabric by experts is shorter than that by non-experts. The fact may be ascribed to the result of long training of experts who inspect fabric defects. (3)The eye-movement pattern shown by experts is almost unchanged irrespective of the fabric speed. But, the eye-movement pattern of non-experts is much different from that of experts in case of high speed fabric.

In the first report the outline of the continuous multi-color printing equipment is mentioned. At this system, reappearance of liquid sorption to slivers is the most important.
Therefore, we carried out the fundamental test for dye liquid sorption to slivers by using the especially developed model equipment.
Consequently we mainly found the following three results.
(1) The diameter of holes in the dye liquid holder has a mutual relationship to the dye liquid viscosity in the new system. At 1.3cp of viscosity, 100μm (0.45Pa.s/m of air resistance) of dye liquid holder is the most suitable conditions. (2) 310mmHg vacuuming pressure is the most suitable. (3) The type of substrate and fineness do not influence machine conditions which give us the best results.
