A Study on the Deing of Polyester/Cotton Fabric with Indigo

In this paper polyester/cotton fabrics were dyed with indigo,the effects of the acid-base value,dyeing temperature,and dyeing time on the surface deep of the fabric.Were disscused The results showed that the deep of the fabric decreased with the increasing of acid and the base,but increased with the increasing of dyeing temperature(not than 120℃),under 120℃ declined with the long of dyeing time.
