Abstract
PP-PHE blends were prepared by mechanical blending using relatively high molecular weight polyhydroxyether(PHE) and polypropylene polymers. PP-PHE blends were prepared and characterized for the purpose of obtaining a dyeable PP fibers with the composition of less than 10 wt% of PHE. Dyeable PP fibers were acquired through the melt spinning of the PP-PHE blend of which PHE composition is less than wt% of PHE. The resultant fibers had tensile strength of 2~3 g/d, elongation of 330~600 %, initial modulus of 22~46 g/d and yield stress of 1.0 g/d, and exhibited markedly improved dyeing ability i.e. higher absorbance, higher dye adsorption and deeper shade than those of pure PP fiber.
