摘要： An acrylonitrile-based precursor fiber for carbon fiber which is produced from an acrylonitrile copolymer containing 96.0 to 98.5 wt.% of acrylonitrile units and has a tensile strength of 7.0 cN/dtex or more, a tensile modulus of 130 cN/dtex or more, an iodine adsorption number of 0.5 wt.% or more relative to the total weight of a fiber, a degree of crystal orientation pi of 90 % or more as measured by the wide angle X-ray diffraction method and a coefficient of variation for tow fineness of 1.0 % or less. The precursor fiber can be used for producing a high quality carbon fiber with a calcination for a relatively short time at a low cost, since it has a high strength, a high modulus, a high compactness, a high degree of orientation, and a low coefficient of variation for tow fineness.

摘要： An object of the present invention is to provide an apparatus and a process for producing a windable carbonaceous material sheet, which is obtained by continuously curing a long uncured fiber sheet which is obtained by using short fibers to make paper and which contains uncured resin to produce a resin-impregnated cured sheet, and then continuously carbonizing it, and its production process. For the object, a long uncured fiber sheet (la) is conveyed by conveyance means which is equipped with one rotation belt set (2) comprising a drive roll ( 2a ), a follower roll ( 2b ), and an endless belt (2c) which is put on and around these rolls (2a, 2b). A resin-impregnated cured sheet (lb) is produced by heating and pressurizing the uncured fiber sheet ( la) by resin curing means (3) which is arranged so as to nip the uncured fiber sheet through the endless belt (2c). Further, the resin- impregnated cured sheet is continuously conveyed in a horizontal direction, and then is carbonized by the apparatus for producing a carbonaceous material sheet which is equipped with a carbonization treatment chamber for carbonizing a carbonizing material and guide rolls which are provided in the carbonization treatment chamber, so that a carbonaceous material sheet is continuously produced. Then, this iswound up. Accordingly, production efficiency is remarkably improved, and its handling property and conveying property are excellent.
