The Effect of Hyperbranched Polymers on the Dyeing Properties of Polypropylene Fibers

Abstract:

3% hyperbranched polymer was incorporated into polypropylene and dyed with Disperse Blue 2BLN. The observed enhancement of dye uptake can be attributed to the introduction of polar groups. The finding that dye uptake on the modified fiber reached a maximum at 110°C suggests that “saturation” had occurred. While the washing fastness of dyed fabrics made from polypropylene fiber which had been modified with hyperbranched polymer was very good, the fastness of the dyeings to light was poor. The incorporation of 3% hyperbranched polymer into polypropylene prior to fiber spinning had no effect on the physical properties of the fiber，however markedly enhanced the dyeability of polypropylene.
