  • The objective of this study was to analyze the effect of the dissolution of detergent on washing and rinsing efficiency, and the possibility of saving detergent in washing. Washing and rinsing efficiency were reviewed in three different ways : A method was to input dissolved detergent by the use of rapid detergent dissolution instrument, B method was to input dissolved detergent beforehand, and C method was to input undissolved detergent. The results were as follows 1. A method > B method > C method was shown in detergency with washing time and three method's gaps were reduced because detergent dissolution effect was reduced by mechanical action in proportion of washing time. Especially, according to detergency of A method of 0.07% and C method of 0.1% was appeared approximately, saving detergent was expected by rapid dissolution of detergent. 2. A method > B method > C method was shown in detergency with washing temperature. As the washing temperature rose, the detergent reached chemically more activated state and become easily soluble. It resulted for the detergent to penetrate and adhere to laundry easily. 3. A method > B method > C method was shown in detergency with detergent concentration and C method was more sensitive than A, B method against change of detergent cocentration. Rapid detergent dissolution made it possible not only to enhance the washing efficiency but also to save the detergent because detergency of A method in low concentration is higher than that of C method. 4. A method $\geq$ B method > C method was shown in rinsing ratio with detergent input method. It indicated input dissolved detergent was advantageous in rinsing. 5. The result of anion surfactant concentration test of each process with detergent input method was shown like that A method In B method > C method in washing and reverse result was shown in rinsing. The anion surfactant concentration of C method was low during washing but high during rinsing. This was identical with previous results which shown the washing and rinsing efficiency improved with dissolved detergent usasge. 6. C method > B method > A method was shown in the degree of remaining detergent after rinsing. There was no remaining detergent after second rinsing in A and B method, but in C method four rinsings were required for the same result. Consequently, in A and B methods, less water and electricity were used, and less abrasion of cloth.

  • The purpose of this study is to research source of soil which is available for non-detergent course, and to develop optimum non-detergent course of washing machine for water soluble soil. The water soluble soil such as grape juice, soy bean paste and soy sauce were easily removed from the fabric but the oil soluble soils such as sesame oil and steak sauce were insurfficiently removed in washing solution without detergent. In the absence of detergent, amount of residual soils increased linearly with increasing number of soiling and washing. To search optimum conditions of washing for non-detergent course, the effect of temperature, washing time and washing method on detergency of soil in non-detergent washing solution was examined. The optimum washing temperature and washing time for non-detergent course were about $40^{\circ}C$, and 7 minutes, respectively. And in the non-detergent washing solution, midterm drain-resupply of water during washing process was good for removal of water soluble soil.

  • This study investigated the detergency and functionality of laminating finished fabrics for outdoor wear based on repeated washing. Laminating finished fabrics were selected as the main fabrics for outdoor wear and used as test fabrics. The effects of outdoor exclusive detergent and normal neutral detergent were examined according to washing time, temperature, rpm and detergent concentration based on the use of a Terg-O-Tometer. Re-soiling of the test fabrics was measured by Florio-Mersereau. Permeability, water repellency, water resistance and absorbency were estimated to measure improvements and effects in regards to outdoor exclusive detergent in optimal washing conditions. The detergent effect of outdoor exclusive detergent was superior compared to normal neutral detergent. Re-soiling was lower with exclusive outdoor detergent than with normal neutral detergent. The measurement of functionality for laminating finished fabrics before and after washing indicated that functionality was decreased with repeated washing.

  • This study investigated the effects of the alkaline detergent and acid rinse used for cleaning milking machines on the rubber composition of the newly-developed teat cup liners. The samples prepared for use in the clean-in-place process were analyzed by ultraviolet spectrophotometer, ion chromatography and liquid chromatography. In the absorption spectrum of the first sample solution, the form of absorbance or absorption peak was largely different, compared to the absorption spectrum of alkaline detergent alone, but in the absorption spectra of the second and third sample solutions, the absorbance decreased, which was similar to the absorption spectrum in the pure acid detergent. In the ion chromatogram, two main peaks only, which might be shown by the pure alkaline detergent alone, were measured. In the liquid chromatograms, however, new peaks were observed in addition to the two main peaks caused by the pure alkaline detergent alone, which suggested that various molecular materials were created or eluted from the liner by the reaction with the alkaline detergent, but when washed with the acid detergent, any ion species were not produced. Therefore, we propose that an acid rinse should be applied, after cleaning the milking machine with the alkaline detergent.

  • This study investigated the effect of mixing protease and lipase on detergency. The detergency of protein soiled, oil soiled and protein-oil soiled cloths and the relative hydrolytic activity of enzymes were examined. The protease-lipase added detergent solution was most effective for the removal of protein in protein-oil soiled cloths. This is because the lipase removed the protein that was physically bound to oil as well as the protease removed the protein. The protease added detergent solution was second effective, the lipase added detergent solution was third effective, and the detergent solution without protease and lipase was the least effective. The protease-lipase added detergent solution was also most effective in the oil removal from protein-oil soiled cloths. Unlike in protein removal, however, the protease added detergent solution was more effective in oil removal than the lipase added detergent solution. This is because the removal of oil bound to protein by protease was more effective than the removal of oil by lipase. In soiling-washing cycles, however, the effects of lipase increased, and as a result, the detergency of protease added detergent solution and the lipase added detergent solution became similar.

  • The purpose of this research is to provide accurate information of household washers and detergents for consumers, so that help the producers who make washing machine and detergent to get basic material and also help consumers to choose washing machine. Experiment was proceed with two type of washers to compare energy consumption, washing performance, rinsing effectiveness further, damage caused by entanglement of laundry and fabric was assessed. Detergent P and T were used to compare the performance related to differences of ingredients of detergent. Soiled fabrics of EMPA 108 set were used to evaluate performance of washing by different types of contamination. A summary of experimental results are : First, for the consumption of water, drum-type washer consumed 53% less than pulsator-type washer. On the other hand, the washing time was almost similar for both these machines, but pulsator-type washer showed shorter progress, implying that power saving was more efficient in this case. Second, the drum-type washer showed better performance for contamination with all types of detergent, but the pulsator-type washer showed better rinsing performance. Third, the drum-type washer performed less data of tangle level and fabric damage. Fourth, detergent "P" exhibited better washing performance than did detergent "T", regardless of the type of soil. And with no limit of detergent variety, water-soluble protein soil showed high removal rate, liposoluble soil especially pigment was hardly removed.

  • SLES를 주성분으로 사용한 액체세정제는 공기 중에 노출하여 방치하는 경우 표면에 피막이 형성되는 경우가 있다. 이는 제형 중의 수분이 증발하면서 세정제 주성분인 계면활성제의 농도변화로 인한 미셀의 상변화로 판단된다. SLES는 30~60% 영역에서 강한 육방정계 액정상이 나타나고, 60% 이상에서는 라멜라 액정상을 보인다. 본 연구에서는 SLES 주성분으로 사용된 액체세정제의 표면 겔링 현상은 내용물에서 수분 증발로 인하여 발생하는 현상이다. 액체세정제에서 수분이 증발되면서 계면활성제의 농도가 높아지는 결과였다. 표면 겔링 상태는 편광현미경으로 관찰한 결과 혼합 계면활성제 시스템의 액정상으로 확인되었다. 결론적으로 SLES를 주성분으로 사용하는 처방에서 겔링 필름 형성을 방지하기 위하여 수용성이 좋은 AOS를 증량하고 액정형성을 방지할 수 있는 이차 계면활성제인 SAS를 도입하고, 하이드로트로프로 SXS와 PEG1500을 적용하였다. 이와 같이 개선된 액체세정제 처방4와 5는 공기 중에 노출되어도 표면에 피막이 형성되는 겔링현상을 방지할 수 있었다.
