Title: Production of acrylic precursor yarn for carbon fiber
Inventor: NAKAJIMA ATSUSHI
IPC: D01F6/18
Filed: 1991-07-25
Abstract: PURPOSE:To obtain the title high-strength yarn causing little fluff even in stretching at a high draw ratio by drawing undrawn yarn of acrylic yarn in hot water at a specific draw ratio, drying, densifying and then subjecting to two-stage pressure steam drawing under a specific condition. CONSTITUTION:First, an acrylic polymer solution is spun and drawn in a hot water bath at 3-5 draw rations. Then, the drawn yarn is dried, densified and subjected to two-stage drawing in pressurized steam under a condition satisfying the formula >>n1-n2>=1 and T1<T2 (n1 is draw ratio in the first-stage pressurized steam; n2 is draw ratio in the second-stage pressurized stage; T1 and T2 are temperatures of the first-stage and the second stage pressurized steam) to give 10-25 times total draw rations. The temperature of the pressurized steam is 110-160 deg.C. Before drying and densifying, oiling is preferably carried out in order to prevent fusing of yarn and to maintain bundling of yarn.
