Effect of Surface Modification on the Properties of a Superfine Down Powder Filled Polypropylene Fiber

Abstract

ABSTRACT:The superfine down powder (SDP) was chemically modified using phenyl isocyanate (PI) and octadecyl isocyanate(ODI), respectively. The wetting behavior of water on the SDP surface was observed by the contact angle. The modified and unmodified SDP-filled polypropylene (PP/SDP) fibers were prepared and characterized by the moisture absorption experiments and thermal and mechanical analysis. The PI-and ODI-modification improved the hydrophobic property of SDP, and the excellent moisture absorption of SDP remained as such. The addition of SDP improved the moisture absorption and thermal stability of the PP fiber. The modification of PI and ODI strengthened the mechanical property of the blend fiber.
