Economical One Step Process For Simultaneous Application Of Pigment Dyeing And Wrinckle Recovery Finishing Of Cotton Fabrics

Özet

Main objective of this study is to combining pigment dyeing with N,N’-1,3- dimethylol- 4,5- dihydroxyethylene urea (DMDHEU) durable press finishing in one step pad-dry-cure process. Dry wrinkle recovery angle (WRA), rubbing fastness and colour strength (K/S) values of specimens were measured before and after one/five/ten times washing treatments for determinating optimum process conditions of combining process. The results indicated that good durable press performance and higher dye depth could be obtained with the one step process (80 g/L DMDHEU, 3 g/L pigment dye, 60 g/L binder, 12 g/L catalyst, 10 g/L antimigration agent, cured at 150 °C for 4 min.). It exhibited good abrasion strength and good rubbing fastness values.
