FIGURE 2 Hyperbranched polymer application profile.
The HBP treated and untreated PET fabrics were subjected to fi ve repeated wash-
ing fastness test for 30 min using sodium carbonate (2 g/l) and detergent (5 g/l) at
60°C, as shown in Figure 3.

Dyeing Procedure with Acid Dye
The dyeability of the hyperbranched treated PET fabric and untreated polyester fabric
were examined using C.I. Acid Red 114 (AR 114). All samples were dyed competitively
