형광증백된 모직물의 광황변화에 미치는 산화방지제 및 소광제 사용 효과

모직물의 광황변성은 형광증백제로 증백된 경우, 미증백직물에 비해서 현저하게 증가하는데, 특히 직물을 습윤상태에서 노광하는 경우에 그 경향이 강하다. 그래서 형광증백된 모직물의 광황변에 대한 산화방지제 및 일중항 산소소광제의 효과를 건/습 상태에서 검토하였다. 모직물로서 평직물(중량 200g/㎡), 형광증백제로서 Uvitex NFW(1％ owf)를 사용하였다. 또..

Wastewater Treatment.

Large industrial laundry facilities and smaller drycleaning facilities are required to deal responsibly with the wastewater they generate. Each plant has several different wastewater treatment options to choose from. In typical wastewater recovery and tre

Stable Free Radical Formation in Photofading Processes of Ractive-Dyed Cotton Fabrics in the Presence of Finishing Agents.

Researchers in Hungary attempted to elucidate the role of stable free radicals in the photodegradation of reactively dyed cellulosic fabrics. Experiments exposed cotton to light from a high pressure mercury vapor lamp and evaluated photofading based on determinations of color differences, measurements of changes in optical density, and th..
