Fabrication method of functional micro/nano structures over large-area, flexible and high curvature surfaces, by drawing a fiber from a preform
The method for drawing a fiber with a textured surface comprises the following steps: forming of a preform from which the fiber is to be drawn with a textured surface; addition of an outer layer to the textured preform to preserve the shape of the texture of the preform surface during the drawing operation; drawing of a fiber from the preform, whereby the fiber keeps the formed texture of the preform surface and removing the additional outer layer to leave the original surface textured fiber exposed. The obtained fiber can be used as a mold to form a textured hollow channel in another material, as a surface coating and as a pressure detector.
Process for producing a surface covering with an embossed printed surface
A process for producing a surface covering with an embossed printed surface is described. A substrate (16) is continuously moved through a production line, and this substrate (16) is first provided, in a printing equipment (12), with a printed pattern and thereafter, in an embossing equipment (14), with an embossed pattern, which is registered with the printed pattern. The printing equipment (12) produces the printed pattern in-line with the production of the embossed pattern. During printing in the printing equipment (12), the printed pattern is stretched or compressed, dynamically responsive to indicators of misalignments between the printed pattern and the embossed pattern, so as to correct or prevent the misalignments. A production line for carrying out this process is also proposed.
Activated composite web for absorptive devices
An activated composite web includes a nonwoven layer, and a formed film layer attached to the nonwoven layer. The formed film layer includes a plurality of first apertured protuberances having a mesh count of at least 35, and a plurality of second apertured protuberances. Each of the second apertured protuberances has a cross-sectional area larger than each of the first apertured protuberances. A plurality of first lanes are aligned in a first direction and have a first width extending in a second direction substantially perpendicular to the first direction. The first apertured protuberances are located in the first lanes. A plurality of second lanes are aligned in the first direction and have a second width, less than the first width, extending in the second direction. The first lanes and the second lanes alternate with each other in the second direction. The second apertured protuberances are located in the second lanes.
Method for producing thin polarizing film
The present invention provides a method of producing a thin polarizing film having both excellent optical characteristics and excellent in-plane uniformity. The method of producing a thin polarizing film includes stretching a thermoplastic resin substrate in a first direction, followed by formation of a polyvinyl alcohol-based resin layer on the thermoplastic resin substrate to prepare a laminate and shrinking and stretching the laminate in the first direction and a second direction, respectively.
System and method for controlling curl in multi-layer webs
A system and method for controlling curl in multi-layer webs. The method can include providing a coated web, curing the coating to form a multi-layer web, and stretching the web during curing of the coating. Some coatings shrink at least partially when cured such that curing the coating induces a strain in the multi-layer web. Stretching the web occurs during curing to induce an opposing strain that at least partially counteracts the strain induced by curing to form a multi-layer web having a desired curvature. The system can include a curing section configured to cure the coating, and can further include a web stretching section, which can be located proximate the curing section and can be substantially coincident with the curing section, such that the web is stretched while the coating is cured.
System and method for manufacturing optical display element
A system for manufacturing an optical display element by laminating an optical film on one surface of a rectangular organic light emitting display panel, the system including: a panel supply unit to which an organic light emitting display panel is supplied; a panel conveying unit which conveys the supplied organic light emitting display panel; an optical film supply unit which supplies an optical film by unwinding the optical film from a raw optical film roll; a laminating unit which laminates the optical film on one surface of the organic light emitting display panel; and a turning unit which rotates the organic light emitting display panel by 90? before the optical film is laminated on one surface of the organic light emitting display panel when a width-directional edge of the supplied organic light emitting display panel does not correspond to a width of the raw optical film roll.
Method of producing thin polarizing film involving in-air stretching, underwater stretching, and stretching while drying
A method of producing a thin polarizing film having an excellent polarization degree includes, forming a polyvinyl alcohol-based resin layer on a thermoplastic resin substrate to prepare a laminate, subjecting the laminate to underwater stretching in an aqueous solution of boric acid and stretching the laminate while drying the laminate after the underwater stretching.
