20130295811 | CARBON-FIBER-PRECURSOR FIBER BUNDLE, CARBON FIBER BUNDLE, AND USES THEREOF - Provided are: a carbon fiber bundle which has a large value of single-fiber fineness and excellent productivity and which, despite this, contains few interlaced single fibers therein and has excellent spreadability; and precursor fibers which are suitable for use in producing the carbon fiber bundle. The precursor fibers are a carbon-fiber-precursor acrylic fiber bundle which comprises a polyacrylonitrile copolymer comprising 95-99 mol % acrylonitrile units and 1-5 mol % hydroxyalkyl (meth)acrylate units and which has a single-fiber fineness of 1.5-5.0 dtex. In the acrylic fiber bundle, the cross-section of each single fiber which is perpendicular to the fiber axis has a shape that has a roundness of 0.9 or less. The roundness is a value determined using equation (1) where S and L are the cross-sectional area and the circumferential length, respectively, of a single fiber which are obtained by examining, with an SEM, the cross-section of the single fiber which is perpendicular to the fiber axis and analyzing the obtained image. | 11-07-2013 |
20140212663 | POLYACRYLONITRILE-BASED COPOLYMER, POLYACRYLONITRILE-BASED PRECURSOR FIBER FOR CARBON FIBER, CARBON FIBER BUNDLES, PROCESS FOR PRODUCING STABILIZED FIBER BUNDLES, AND PROCESS FOR PRODUCING CARBON FIBER BUNDLES - Provided are: a polyacrylonitrile-based precursor fiber for the production of a carbon fiber having a large single-fiber fineness, said precursor fiber ensuring high heat stability of a spinning dope and excellent productivity; and a copolymer suitable for the production of said precursor fiber. Also provided are: high-quality carbon fiber bundles which have a large single-fiber fineness and excellent productivity; a process for producing the same; and a process for producing flameproofed fiber bundles suitable for the production of the carbon fiber bundles. A polyacrylonitrile-based copolymer which comprises 93.0 to 99.4 mol % of acrylonitrile units, 0.5 to 4.0 mol % of (meth)acrylamide-based units, and 0.1 to 3.0 mol % of unsaturated carboxylic acid hydroxyalkyl ester units and in which the (meth)acrylamide-based units are (meth)acrylamide units and/or (meth)acrylamide derivative units having a molecular weight of 105 or less; a precursor fiber comprising the copolymer; a process for producing flameproofed fiber bundles which uses precursor fiber bundles consisting of the precursor fiber; carbon fiber bundles; and a process for production thereof. | 07-31-2014 |
