The roller in the coagulating agent and the wet process which uses this or the dry wet

摘要

PROBLEM TO BE SOLVED: To provide a roller in a coagulation liquid, which can sufficiently inhibit the stick-slip of a travel yarn on a guide or roller for changing the route of the yarn obtained by introducing and coagulating a dope discharged from discharging holes formed in a spinneret into the coagulation liquid, and to provide a wet or dry-wet spinning method using the same.;SOLUTION: In the roller 3 for changing, in a coagulation liquid, the routes of yarns Y1, Y2 formed by introducing and coagulating, in the coagulation liquid, a spinning raw liquid discharged from the discharging holes of a spinneret 1 in which many discharging holes are formed, wherein the roller is a forcibly driven roller which is forcibly driven to freely rotate, and a liquid suction roller whose yarn-contacting surface for contacting with the travel yarn is formed with a liquid-passing member and used for sucking the coagulation liquid from the liquid-passing member to the inside of the roller; and the wet or dry-wet spinning method using the same.;COPYRIGHT: (C)2009,JPO&INPIT
