Abstract: Molten polyester sheet (2) is solidified by cooling it on the surface of a mobile cooling medium on which water film (7) is formed, and the sheet is stretched at least 4.5-fold in overall stretching ratio in a longitudinal direction through a plurality of stretching steps. Since casting is conducted via the water film, water is absorbed in the surface layer and the interior of the cast sheet, thus facilitating orientation by stretching in the longitudinal direction and lowering the stretching temperature. As a result, stretching with a high stretching ratio can be attained by multi-stage stretching without conducting high-temperature stretching. Thus, this process can accelerate film formation, improve productivity, and provide a film having reduced unevenness in thickness, less surface roughness and excellent abrasion resistance.

Abstract: The specification discloses a thermal stencil paper for mimeograph, having a uniform shape of pores and well-balanced retainability and permeability of printing ink. Thermal stencil paper for mimeograph formed by laminating a porous support member comprising polyester fibers on one surface of a polyester film, characterized in that the porous support member forms a reticulate body having a fusing point at which the fibers are fused to one another, a film which straddles the fibers, and which has a thickness smaller than an average fiber diameter, being formed at some of the fusing points in the reticulate body. Since such thermal stencil paper for mimeograph is provided, the printed matter obtained by a mimeograph using this stencil paper has a high quality of image, and set-off does not occur. Such printed matter is highly convenient to transport.

Abstract: This invention discloses heat-sensitive stencil paper and a production method thereof. Since no adhesive is used in this paper, the permeability to printing ink is not affected, and thus high-quality prints are obtained. The elimination of the use of adhesive prevents the decrease in resistance to ink, the adhesion to a thermal head, and emission of toxicious chlorine and improves the stability of film coating and productivity. This stencil paper is obtained by thermally bonding a polyester film and a porous support comprising a polyester fiber and co-stretching them, and the peel strength between the film and the porous support is at least 1 g/cm. Accordingly, prints obtained by stencil printing have very high quality.

Abstract: A biaxially oriented polyester film wherein the ratio (=IMD /IND) of the peak intensity (IMD) in the longitudinal direction to the peak intensity (IND) in the thickness direction determined at 1615 cm by laser Raman scattering method is not less than 6; and a process for production of a biaxially oriented polyester film which comprises the steps of controlling the ratio (A/B) of the maximum thickness (A) of the edge portion of a cast film to the thickness (B) of the central portion in the transverse direction thereof in the range of 2 to 6, biaxially stretching the cast film, and controlling the peak intensity ratio of the biaxially oriented film determined by the laser Raman scattering method in the above-described range. The biaxially oriented polyester film thus produced has a specific orientation in the longitudinal direction, and therefore has great strength in the longitudinal direction and small irregularity in properties such as thickness or birefringence.

Abstract: A method of producing a thermoplastic resin film capable of giving a biaxially oriented polyester film at a speed of as high as at least 400 m/min and an apparatus therefor. Specifically, a method of producing a thermoplastic film, wherein a molten thermoplastic resin film is closely bonded to, and cooled and solidified, on a cooling medium to prepare a cast film, characterized in that the surface temperature of the medium immediately before the melt is brought into contact therewith is higher than a glass transition temperature Tg of the thermoplastic resin but is lower than a melting point Tm thereof. The apparatus has a heater device and a cooler provided in the cooling medium so that the surface temperature of the medium immediately before the melt is brought into contact therewith is higher than the glass transition temperature Tg of the thermoplastic resin but is lower than the melting point Tm thereof, and the surface temperature of the medium immediately before being peeled off is maintained to be lower than the glass transition temperature Tg of the thermoplastic resin.

Abstract: PROBLEM TO BE SOLVED: To manufacture a film of high quality having no surface defect with good productivity. SOLUTION: A process for manufacturing the film having no surface defect includes the steps of reducing a draft ratio in a forward direction by directing a mouthpiece position toward a rotating direction of a cooling drum, and bringing it into close contact with the drum by an electrostatic applying casting method. Thus, a cast sheet having no surface defect can be manufactured. COPYRIGHT: (C)2004,JPO
