A method for continuously manufacturing an optical display device comprises feeding a continuous web of optical film laminate including a continuous web of releasable film that includes a conductive layer and an optical film sheet that includes a conductive layer formed on the releasable film, bending the releasable film at a peeling body located in close vicinity of a lamination position, collecting the releasable film and thereby peeling the optical film sheet from the optical film laminate, sending the optical film sheet to the lamination position, and laminating the optical film sheet with a panel member which is conveyed to the lamination position by a panel conveying channel which makes at least a double-storied structure with a portion of a collecting channel where the releasable film is collected, attenuating static electrification generated on the optical film sheet, and continuously laminating the optical film sheet with the panel member.

Optical film laminate used for continuous lamination to panel component

A continuous web of optical film laminate comprising, an optical film comprising a first substrate and an adhesive layer on the first substrate, a releasable film comprising a second substrate and a releasably treated layer on the second substrate, the releasably treated layer being in contact with the adhesive layer, a first conductive layer between the first substrate and the adhesive layer, and a second conductive layer between the second substrate and the releasably treated layer. The first conductive layer and the second conductive layer comprise a static electrification prevention material, such that the optical film with the first conductive layer, and the releasable film with the second conductive layer, both have a sheet resistance of 10&#x3a9;/sq or less.

To provide a continuous web of optical film laminate provided with static electrification prevention function which allows for promptly attenuating static charge of optical film sheet and carrier film electrified by peeling action in RTP lamination method and apparatus. The problem has been solved with a continuous web of optical film laminate for using in RTP lamination method and apparatus, in which static electrification prevention function is provided to optical film sheets and a carrier film configuring the continuous web of optical film laminate, such that sheet resistance of each of the optical film sheets and the carrier film is 10&#x3a9;/sq or less so as to promptly attenuate static charge of the carrier film to be collected, which is statically electrified by peeling action, and the optical film sheets to be laminated to panel components, which are also statically electrified by peeling action.

A biodegradable filament of polyglycolic acid resin having practical properties represented by high tensile strength and knot strength is produced. A polyglycolic acid resin having a residual monomer content of below 0.5 wt. % is melt-spun, quenched in a liquid bath of at most 10&#xb0; C. and then stretched in a liquid bath of 60-83&#xb0; C. to produce a polyglycolic acid resin filament having a tensile strength of at least 750 MPa and a knot strength of at least 600 MPa.

Process of making polyglycolic acid resin filament

[Object] In a fishing line for capturing large fishes made by a polyvinylidenefluoride resin filament, a polyvinylidenefluoride resin filament wherein even by enhancing the tensile strength at break by enlarging the filament diameter than that of usual fishing line, an appropriate tensile elongation at break can be obtained, so that the rapid and enormous impact generated when large fishes have taken the bait can be reduced, and that has a homogenous fiber structure which generates almost no inner cavity when forming a filament with a large diameter, is developed.

Modified polyvinylidenefluoride resin monofilament and method for manufacturing thereof

Monofilaments comprising resin compositions which contain 1% by mass or more of a comonomer component (for example, hexafluoropropylene), have an intrinsic viscosity of 1.3 dl/g or more and a melting point of 165&#xb0; C. or higher and contain a PVDF-based resin. Owing to the above composition and physical properties, the crystallinity and elastic modulus of the PVDF-based resin are altered. As a result, an appropriate flexibility can be imparted to the monofilaments while preventing deterioration in the mechanical properties.
