A novel cutting-edge structure and method and apparatus for manufacturing the cutting-edge structure is provided. The cutting-edge structure is comprised of naturally derived or renewable material at greater than 50% by volume fraction. In one embodiment, the naturally derived material is a cellulose nanostructure such as a cellulose nanocrystal. The cellulose nanocrystal is processed using a base or mold structure to provide a cutting edge of any shape such as linear or circular edge structures. The process includes dual cure steps to produce an optimal cutting-edge structure without shrinkage. The formed cutting-edge structure can be utilized as a razor blade as it is formed with very sharp tip and edge suitable for cutting hair. The base structure can form one or more cutting-edge structures simultaneously.

A release agent composition for tire-molding contains: (A) 100 parts by mass of an organopolysiloxane containing at least two hydroxy groups bonded to a silicon atom in one molecule and having a viscosity at 25° C. of 10,000 mPa.Math.s or higher; (B) 10 to 100 parts by mass of an organohydrogenpolysiloxane containing at least two hydrogen atoms bonded to a silicon atom in one molecule relative to 100 parts by mass of the component (A); (C) 10 to 10,000 parts by mass of water relative to 100 parts by mass of the component (A); and (D) 2 to 70 parts by mass of a polyvinyl alcohol relative to 100 parts by mass of the component (A). The release agent composition for tire-molding is excellent in release. Molding and vulcanizing tires repeatedly in succession a larger number of times without applying a release agent after once applying a release agent is realized.

Methods for making a microstructured tool having interspersed topographies are disclosed, and the production of articles therefrom. The article has a major surface including first microstructural features and second microstructural features arranged in a pattern visible at least when viewed normal to the first major surface. The first and second microstructural features are different relative to each other, and are selected from the group consisting of cones, diffraction gratings, lenticulars, segments of a sphere, pyramids, cylinders, fresnels, and prisms.

The present invention relates to compositions in the form of silicone oil emulsions intended to be applied to curing bladders as a mould-release agent during tyre production.

The present disclosure provides a fabric structure including at least one fiber interlaced in a first pattern, and a surface layer having a second pattern not corresponding to the first pattern. The fiber includes a thermoplastic component and a functional component. The surface layer comprises a fused portion of the thermoplastic component and covers the functional component.

A fabrication process and apparatus for producing three-dimensional objects by depositing a first polymer layer, printing a first ink layer on to the first polymer layer, depositing a second polymer layer on to the first ink layer, and printing a second ink layer on to the second polymer layer. The deposition and printing steps may be repeated until a three-dimensional object is formed. The inks used to form at least one of the first and second ink layers may include dyes or pigments so that the three-dimensional object may be a colored three-dimensional object.

A method for manufacturing a concave diffraction grating is provided. The method includes the steps of: positioning a flat mold and a concave substrate such that a pressing surface, having a groove pattern of a diffraction grating, of the flat mold faces a concave surface, coated with a resin, of the concave substrate; pressing the pressing surface against the resin coated over the concave surface by pressurizing the flat mold using a fluid; and curing the resin having the groove pattern transferred thereto by being pressed by the pressing surface. This makes it possible to improve load non-uniformity and manufacture a concave diffraction grating with high surface accuracy.

Provided is a manufacturing method for a substrate having a microstructure. The manufacturing method for a substrate having a microstructure comprises the steps of: forming a microstructure on the upper surface of an auxiliary substrate; coating a base solution on the microstructure; forming a base substrate covering the microstructure by heattreating the base solution; and removing the auxiliary substrate from the base substrate.
