진공청소기 粉塵을 모델로 한 固形汚染의 洗滌性에 관한 硏究
姜仁淑,金聲連 國立昌原大學校 基礎科學硏究所 1990 基礎科學硏究所論文集 Vol.2 No.-
This study has treated the effects of fiber, surfactants, temperature, surfactant concentration, pH, electrolyte, fatty acid contents and mechanical force on the removal of particulate soil from fabric, vacuum cleaner dirt was used as model particulate soil. The fabrics were soiled with mixture of vacuum cleaner dirt and fatty soil, and washed in Terg-O-tometer. The detergency was evaluated by measuring reflectance of a fabric before and after washing. The results were as follows. 1. The fiber type showed a different pattern of soil removal with surfactants. In general, particulate soil removal increased in the following order Acetate>PET. Nylon>Cotton. Particulate soil removal, which is affected by the surfactant type, increased in the following order ??????≥ Soap>SLS>DBS>Tween 80. 2. The influence of temperature on the particulate soil removal was very complex because efficiency of removal was varied with surfactant and fiber types. The washing effiency of ????? was highest at around 40℃ and 60℃ with cotton and PET but the washing efficiency of DBS was the highest at 60℃ with cotton, decreased monotonously with increasing temperature with PET. 3. The detergency of particulate soil increased with increasing surfactant concentration at relatively low concentration and then levelled off above some optimum concentration. 4. The removal of particulate soil increased with increasing pH and mechanical force. 5. Effect of electrolyte on the particulate soil removal was depended on the concentration of the surfactant. At low concentration of surfactant addition of electrolytes improved soil removal but above the some concentration no effect was observed. At high concentration of surfactant, Vie .. 0.6%, the maximum washing effect is reached without added electrolyte. These result indicate that added electrolyte only influence the adsorption of surfactant on the soil and fiber 6. Fatty acid content in the soil did not influence on particulate soil removal without regard to surfactants.
紫外線을 利用한 Nylon에의 Acrylic acid의 Graft
金聲連 忠南大學校 1968 論文集 Vol.7 No.-
For the purpose of comparison to the methacrylic acid-grafted nylon, acrylic acid was grafted. onto nylon following the same procedure used to graft methacrylic acid, The properties of the grafted films were studied. The results showed that the efficiency of acrylic acid was higher than that of methacrylic acid. Standard moisture regain and tentile properties were changed with increasing amounts of grafting as in the case of methacrylic acid-grafted nylon film. On the other hand acrylic acid-grafted nylon film was dissolved in common solvents for nylon in contrast to methacrylic acid-grafted nylon,.
大禾(Miscanthus Neoneocoreensis)의 工業的 利用에 關한 硏究(第一報)
金聲連 忠南大學校 1965 論文集 Vol.4 No.-
"Taewha" is a leind of Miscanthus purpurascens which grows in Kyunggi province. We have examined the chemical composition and febric nature of “Taewha”. The results of the experiment show Taewha can be good rawmaterial for pulp manufacture in Korea where the lack of forest resources is a vital problem in pulp industry.
