摘要: A method of making a fiber involves the sequential steps of: a) extruding as stream solution polymer having concentration 4-24 weight % into non-coagulating fluid; b) stretching while in fluid at spinning draft 25-2000; c) increasing by least 2 to 20-65 %; e) stretch ratio 1.5-10; and f) sufficiently form fiber.
