The impact of neutralization and drying on the washing effects

Abstract

The physico-chemical processes of wetting, solubilization and emulsification are performed during washing of textiles in water upon the impact of detergent, temperature, mechanical agitation and duration. Synergisms of detergent ingredients provide soil removal and prevent soil redeposition. The modem washing processes are based on high dosing of detergent in short cycles and bath ratios. The result of this technological concept can be insufficient rinsing and neutralization which can cause the presence of residues on the textiles after drying. In this paper are presented new perspectives of neutralization with citric acid as well as impact of drying on the damage and whiteness of textiles from cotton and blends of cotton with polyester fibres.
