후염성 폴리프로필렌 섬유 제조(II)

PP-PHE Blend Fiber

PP-PHE blends were prepared by mechanical blending using relatively high moecular weight polyhydrozyether(PHE) and popypropylene polymers. PP-PHE blends were prepared and characterized for the purpose of obtaining a dycable PP fibers with the composition of less than 10 wt.% of PHE. 1)yeable PP fibers were acquired through the melt spinning of the PP-PHE blend of comprising less than 10 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 such as higher absorbance, higher dye adsorption and deeper shade than those of pure PP fiber.
