鄭濟石 한국의류학회 1986 한국의류학회지 Vol.10 No.3

In this research, we tested the textile physical and the sensory properties and the handle of the domestic polyester fabrics were treated with the varying alkaline concentrations and temperatures were tested. The tests were conducted to determine the effects of the alkaline treatment on the changes of the physical and the sensory chrateristics of the domestic polyester fabrics. The results were as follows; 1. When treated with the varying alkaline concentrations from 7.5% to 15% at temperatures from 60℃ to 90℃, the weight decreasing phenomena were shown to as a linear equations increase in that range. 2. As the weight loss increased, the softness and the smoothness were increased but the fullness and the tightness were decreased. 3. The positive correlations were found between the sensory and the physical properties, and the fullness and the tightness, while a negative correlation was found between softness and the smoothness. 4. The regression equations obtained by the sensory chrateristics related with the physical chracteristics were as follows; Softness: Y=84.01-0.74x Fullness: y=0.06+0.78x Smoothness: Y=88.67-0.82x Tightness: y=0.34+0.79x

鄭濟石,李相奎 단국대학교 1989 論文集 Vol.23 No.-

Poly(ethylene terephthalate) filament was dyed with C.I. Disperse Orange 3 in DMF, MCB, and PER dyebath at varying temperature in order to examine the dyeing properties related with the changes in the physical properties. The results of experiment were as follows; 1. Amount of dye uptake decreased in order of PER, MCB, and DMF, and diffusion coefficients of dye were increased according to increasing temperature, but amount of dye uptake were deacreased. 2. Shrinkage and degree of swelling in DMF which interacted with the aliphatic residue of PET were shown better than other solvents. 3. Dye exhausion rate increased the linear proportion with the change in the physical properties increased until the equilibrium dye uptake. 4. In isothermalic condition, degree of crystallinity was increased as time pass.

鄭濟石 慶北工業專門大學 1980 論文集 Vol.17 No.-

Methyl Polysiloxane made from Methyl Cholorosilane is diluted to be 1,2,3,4% (Weight) solution in carbon tetrachloride. After cotton woven cloths is immersed in the solution and cured during the heat setting, the degree of water-repellency is measured by spray method described in KS K 0590. Following result is obtained: 1) Residue of Methyl Chlorosilane mixture, intermediate products of silicones, can be used as a Water-repellency agent. 2) As we treated the cotton fabrics over 2% of Methyl Polysiloxane solution, the effect of Water-repellency were satisfied oven against laundering cotton fabrics for 5 times. 3) Optimum finishing conditions of the Methyl Polysiloxane solution to cotton fabrics are 85±2% of wet up, 60℃ of preliminary dry for 3 minutes, 140℃ of curing for 3 minutes. 4) Tearing strength of Water-repellency finishing to cotton fabrics were diminished 28.5% than of untreated fabrics. 5) 6% (o.w.f.) hydrogen peroxide finishing to cotton fabrics after curing process are contributed to help increasing smoothness, whiteness and aboiding bad odor.

界面活性劑가 有機실리콘 第四級암모늄鹽의 抗菌性에 미치는 影響

鄭濟石,白欽吉 단국대학교 1987 論文集 Vol.21 No.-

After knitted cotton fabric was finished silicone quaternary ammonium salt of antibacterial agent, effects of treatment by nonionic and anionic surface active agent and salt-methanol rinsing on antibacterial properties were investigated. When laundered with anionic surface active agent, cation of quaternary ammonium, antibacterial functional radical from the first laundry was compete masked with anion of surface active agent, and antibacterial properties was decreased extremely after ten times of laundry. But, as a result of milk test, the effect of antibacterial properties was known as positive comparing with unfinished fabric.
