    다국어 초록 (Multilingual Abstract) kakao i 다국어 번역

    The purpose of this study was to investigate the effect of the water-soluble polymers on the removal of deposited calcium on the cotton fabric. The polymers were used sodium carboxmethyl cellulose (Na CMC) and poly vinyl clcohol(PVA). The amount of calcium deposits on the fabric was determined by EDTA-back titration methods.
    The results of this study were as follows:
    1. By increasing the polymer concentration to 0.05g/100ml, the amount of calcium removal was increased, and Na CNC was more effective than PVA.
    2. It seemed that the increase of the rate of calcium removal was due to complex formation between polymer and Na DBS.
    3. When water-soluble polymer was used, the pH, added alkaline builders and temperature of washing solution did not influence on the removal of deposited calcium on the cotton fabric.
    4. The tate of calcium removal was increased with increasing concentration of STPP as sequestering agent. At high concentration of STPP, however, the rate was rather decreased with increasing concentration.
    5. The amount of calcium removal was increased with increasing wash cycle to 3 times.
