Role and application of environmental friendly dyeing carrier OE in atmospheric temperature dyeing of polyester fibers

For decreasing dyeing temperature,realizing energy-saving and environmental-friendly dyeing of polyester fabric,the dyeing performance and process of polyester fabric with environmental friendly carrier OE were investigated.The results showed that carrier OE had plasticizing effect for polyester fibers and could effectively lower the dyeing temperature.When polyester fabrics were dyed at 98 ℃,the addition of carrier OE into dye bath could improve dyeing rate and dye uptake obviously,as compared the bath without carrier OE.The optimal carrier OE dyeing conditions are dye 2%(o.w.f),carrier OE 6%(o.w.f),dyeing at 98 ℃,and holding time for 80 min.Under these conditions,carrier dyeing could obtain color fastness and shade as good as those of high temperature and high pressure dyeing.Migration experiment showed that carrier OE had good migrating property.
