    Effects of a formulation of surfactants (DBS, AOS and APE), zeolite and protease in the model system of phosphate-free home laundry detergents were studied in 100 ppm hard water at pH 9.5 by Scheffé's Symplex Lattice Design. The soil removal of protein, synthetic sebum, mud (Dilivium) and carbon black compounded in soiled fabrics were determined separately and were represented by Scheffe's special cubic equation to predict the soil removal by an interaction between the soils and the component of a detergent.
    (1) It was found that the protease affected not only the protein removal, but also the particulate soils adhered to the fabrics with protein in any surfactant systems.
    (2) The nonionic APE systems were superior to the anionic AOS or DBS system in the detergency of any soils studied. AOS was very similar to APE. The soil removal behavior were dependent on the interaction between the soils and the component of the detergent in hard water.
    (3) Anionic DBS systems were different from other surfactants in low detergency and the interaction between the soils and the component of the detergent. It was deduced that the differences of the soil removal between DBS and AOS would result from the interaction properties of the surfactants with hardness ion. The zeolite and the protease formulated in DBS systems used in hard water were effective to enhance the removing efficiency of perceptible soils.

    The effect of soiling on characteristic properties of moisture permeable water-proofed fabrics was studied by using the second generation Gore-tex® fabrics.
    Soils used in the experiment are airborne dust, oily soil containing equal amount of lauric acid and triolein and a mixture of dust and oily soil (1: 2) . These soils were brought on the substrates in the petroleum benzine solution. The moisture vapor transmission of fabrics was determined by a cup method modifing that of ASTM E-96-66. The adherence of the soils on the fabrics was observed under a scanning electron microscope.
    The moisture vapor transmission of fabrics was decreased with increasing the concentration of the soil in the solution, and became nearly constant at above 0.5 % of dust and mixtured soil, and at above 1.0% of oily soil. The decrease of moisture vapor permeability of the fabrics by soiling was found to be greater in the following order: dust<oily soil<mixtured soil. The adherence of dust was found mainly on the hydrophilic surface of the film of the second generation Gore-tex® fabric. But oily soil was observed on the microporous hydrophobic surface, and the mixtured soil on both sides of the film. It seems that the decrease of the moisture vapor transmission of the fabric is caused by the adherence of these soils on the Gore-tex® film. The moisture vapor transmission of fabric laminated with a nylon tricot as an outer fabric was decreased by soiling more significantly than with nylon taffeta.
