抗静电聚丙烯纤维的研究 Ⅲ.PP-PSUE共混纤维的结构与性能

研究了聚丙烯与抗静电剂ＰＳＵＥ共混纤维的抗静电性能、耐水洗性能、力学性能、结晶性能、染色性能及形态结构。研究结果表明：当抗静电组分加入量在４．０％～５．０％（质量）时，共混纤维具有较好的抗静电性能及耐水洗性能，纤维体积比电阻降至１０９Ω·ｃｍ；ＰＳＵＥ分散于体系的无定形态之中，呈相分离态，其分子不能砌入ＰＰ晶格，共混纤维的染色性能与纯聚丙烯纤维相比有较大幅度的提高。

STUDY ON ANTISTATIC PP FIBER Ⅲ. STRUCTURE AND PROPERTIES OF PP PSUE BLENDING FIBER

The antistatic behavior, wash resistance, mechanical property, crystalline behavior, dyeability and morphology of PP fiber blending with PSUE were studied. It was shown that the blending fiber had good antistatic behavior and wash resistance when antistatic component content reached 4.0%￣5.0%. The bulk specific resistivity of blending fiber descended to 10 9 Ω·cm. The macromolecule of PSUE couldn't enter the crystal lattice of PP, and became separated phase in the amorphous region of PP fiber blending with PSUE. The dyeability of blending fiber was much higher than that of PP fiber.
