  Abstract

One of the major problems in the household machine laundry process is dyes bleeding from coloured garments and then the re-depositing on lighter-coloured garments in the same wash load. Thus it creates staining on the light coloured cloth and also colour loss on the dark coloured cloth. Numerous attempts made to solve the issue but none of the remedies are completely successful. Improper loading of high quantity of dye transfer inhibitor (DTI) polymer also had severe negative effect on coloured garment in terms of colour striping, patchy and unsightly appearance. In this research, the amine based aromatic dye transfer inhibitor polymers pyridine N-oxide (PNO), used for the analysis. The performance of the polymer was optimized for better dye transfer inhibition property in the 쁦n wash liquor against reactive dye. The findings of the research indicate that the performance pyridine N-oxide against reactive dye was excellent over the commercial DTI polymer polyvinylpyrrolidone (PVP). The addition of detergent diminishes the properties of the PVP, but the PNO overcomes that issues and acts well in presence of maximum quantity of the detergent. The research work optimized the amount of DTI polymer required for a single wash load, as 0.25 g. The level of detergent preferably 10 g/l and the pH value of 8. The findings revealed that the PNO polymer performs excellent against all the commercial dyes and also it is noted that the polymer overcomes the shortfalls of commercially available DTI polymers like PVP.
