Process for preparation of a synthetic fiber bundle |
摘要 |
A non-water swelling or a water-insoluble thermoplastic resin, water and an assistant for assisting dispersion of water into the thermoplastic resin are melt-kneaded and the kneaded composition is extruded from an orifice under such conditions that flashing of water is prevented. As the assistant, a water-soluble resin or a water-insoluble resin having a carboxylic acid salt group is used optionally in combination with a surface active agent. The spun product is a fiber bundle in which single filaments having a diameter smaller than 100 mu m are gathered in parallel to one another, and this fiber bundle is easily opened.
