    The nature has been investigated of the clothes yellowed by oily soils. The methods have been investigated to recover whiteness and to prevent yellowing. Natural and denatured oily soils and yellowish matters coexist on the clothes. These three kinds of soils have each specific nature. The denatured oily soils can more easily be removed than the natural oily soils by laundering. The yellowish matters, which are slight in volume and insoluble in organic solvents, are the most important causal matters which increase remarkably the yellowing of the cotton fabrics after a long period of storage.
    The rate of denaturalization of oily soils and degree of yellowing due to yellowish matters are dependent on the kind of fibers and period of storage. The characteristic of yellowed fabrics and degree of recovery of whiteness are also dependent on them.
    The bleaching or washing by hot water is effective to recover the whiteness of cotton fabrics yellowed by oily soils.

  • Studies on Whiteness Retention in Home Laundering Part 5 : Lowering of Whiteness of Clothes Caused by Fluorescent Whitening Agents

    White textiles in the market have mostly been finished with fluorescent whitening agents. During usage, these textiles decrese their original whiteness by losing the effect of fluorescent whitening agents. This article aims to investigate the causes of lowering of whiteness and measures to be taken to prevent it.
    The cause of lowering of effect of fluorescent whitening agents is found to be mostly the colour fading due to drying in the sun light, removal of fluorescent whitening agents due to laundering and weakening of effect of fluorescent whitening agents due to soils and deposited matters soils on clothes. The degree of lowering are dependent on the amount of fluorescent whitening agents used in detergents and clothes, fastness and affinity of fluorescent whitening agents, conditions of laundering and drying, degree of soils on clothes.
    It is difficult for cotton clothes to retain their whiteness if they are dried in the sun light for many hours.
    To keep clothes white, it is recommended to dry clothes with a great care, to soak colored clothes in the highly concentrated solution of detergents containing fluorescent whitening agents and to remove soils and deposited matters.

  • Analysis of Factors Affecting the Perception of Figures

    To investigate factors affecting the perception of figures, relationships have been discussed between figure factors and physical factors. Seven factors have been obtained by a factor analysis performed on 20 figures by determining 22 physical characteristics. Then a factor analysis made on the stimulus threshold of each figure determined by 20 participants has revealed five factors affecting the figure perception. Psychological factors have been related to the physical factor by using a coefficient of partial correlation according to the Hayashi's Quantification Scaling Theory, Type 1.
    Effective factors for all factors affecting perception of figure are an intuitive perception of geometry, abstraction and concretion of the figure, peripheral linearity of the figure and distorsion in horizontal direction. Other physical factors differ from factor to factor of perception.
