    摘要: A nonwoven fabric which contains pitch-based carbon fibers having a high elongation and a high elastic modulus which are not attained in the prior art and is obtained by improving the tensile elongation of carbon fibers derived from mesophase pitch, a felt obtained from the nonwoven fabric, and production processes therefore. The nonwoven fabric contains pitch-based carbon fibers, wherein the pitch-based carbon fibers have (i) an average fiber diameter (D1) measured by an optical microscope of more than 2 μm and 20 μm or less, (ii) a percentage of the degree of fiber diameter distribution (S1) to average fiber diameter (D1) measured by an optical microscope of 3 to 20%, (iii) a tensile elastic modulus of 80 to 300 GPa and (iv) a tensile elongation of 1.4 to 2.5%.

    摘要: A fluoropolymer resin coated member in which the fluoropolymer resin layer has been improved in wear resistance and peeling resistance. When the coated member is used to form a mold for polyester container molding, part of a polyester resin or an oligomer ingredient or additive contained in the polyester resin is prevented from depositing on the mold surface. And a polyester container with excellent luster and transparency can be manufactured. The fluoropolymer resin coated member (1) comprise a foundation (10) and a fluoropolymer resin layer (20) formed thereon, the foundation (10) having a surface roughness of 2 to 10 degree in Root-mean-square slope of profile, the amount of the fluoropolymer resin of the fluoropolymer resin layer (20) being 0.5-8.5 g/m2, and the surface roughness of the fluoropolymer resin layer being 5 degree or less in Root-mean-square slope of profile Δq2. The metal mold for forming polyester resin container can be reproduced in such a manner that amorphous fluoropolymer resin layer 20 applied on the hard surface of foundation 10 of the metal mold for forming polyester resin container is removed by abrasive to obtain mirror finish, then a new amorphous fluoropolymer resin layer 20 is applied on the surface of foundation 10.
