    Dyeing behavior of non-ionic (disperse) dyes on nylon 6, polyethylene terephthalate and triacetate fibers from organic solvents has been studied, and following results are obtained.
    (1) The absorption isotherms are best expressed as a formula according to Nernst's partition law.
    (2) The partition coefficients, affinities of dyeing and heats of dyeing from organic solvents are much smaller than those which one would expect from an aqueous dyeing system.
    (3) The diffusion coefficients are very different by combination of fiber and solvent, rates of diffusion increase greatly with increasing degrees of swelling of fibers by solvents.
    (4) The swelling of fibers are correlated with the solubility parameter of the solvents. The degree of maximum swelling takes place with solvents whose solubility parameter is similar to that of fibers.

    In this paper are reported the effects on the swelling and the diffusion properties of nylon 6 and polyethylene terephthalate (PET) film in 32 organic solvents differing widely in chemical characteristics.The degrees of swelling are correlated with the solubility parameter δ of the solvent. It was observed that maximum swelling take place with solvents whose solubility parameter approaches that of PET δ=10.7 and that of nylon 6 δ=13.6. However the swelling of PET are closely connected with the dispersion component of the solubility parameter δd, and maximum swelling of PET take place with solvents at δd= 8.3.
    The rate of diffusion are correlated with the degree of swelling. The diffusion coefficients of C.I.Disperse Red 17 increase with increasing the degree of swelling of polymers by solvents, but the slope of the lines are different by combination of polymers and solvents.

    Vibration isolators for looms can be classified into following two types, i. e., one is the isolator for a low-speed loom and the otheris the isolator for a high-speed loom.
    The vibration from low-speed loom is mainly impact vibration. Leaf springs are used for the isolator for low-speed loom. The leaf springs are effective to damp the impact vibration.
    The vibration from high-speed loom is both cyclic vibration of low frequency and impactvibration. Coil springs are used for high-speed looms. As the natural frequency of this type is very low, dynamic dampers are effectively used to control the mounting base swinging.

    Fabrics are now expanding their uses for interior decoration, e.g., wall fabrics, etc.They contribute greatly to improvement of visual environment inside rooms.
    The authors heve assumed that the distribution of specular reflection are varied according to the geometrical structures of fabric surface.
    Then, it is concluded that optical properties of fabric are much influenced by the specular reflection of mono-filaments and geometrical structure of fabrics.
