Abstract

The present invention relates to wadding in which short fibers (A) having a single fiber fineness (a) of 0.001-1.0 dtex make up 5-90 mass% of the total mass of the wadding. Measured in accordance with JIS L 1096 Warmth Retention Method A (Constant-Temperature Method): 2010, a 89% or higher warmth retention ratio is obtained in test items made by stuffing 100g of the wadding substantially evenly into a pouch-shaped cover produced by layering two pieces of 45cm-length 100% cotton fabric squares and thereafter sewing shut the opening of the pouch-shaped cover. By means of the present invention, it is possible to provide wadding which has excellent softness and bulkiness and which is ideal for use in down jackets, duvets or other bedding.

Abstract

Provided is a method for producing a cylindrical nanoimprinting mold such that the outer peripheral surface of a cylindrical aluminum substrate is uniformly polished, and it is possible to effectively take advantage of the outer peripheral surface. The method forms an oxide film at the outer peripheral surface (14) of an aluminum substrate (10) after polishing the entire outer peripheral surface (14) of the cylindrical aluminum substrate (10) by means of a polishing body (26), wherein the polishing body (26) is moved in the axial direction to polish in a manner such that at least a portion of the polishing body (26) is protruding beyond the first end (10a) side and second end (10b) side of the aluminum substrate (10), and the portion of the polishing body (26) protruding beyond the aluminum substrate (10) is disposed on and supported by a cylindrical first support member (18) and second support member (20).

Abstract

This method for producing a mold for nanoimprinting in which a minute bumpy structure has been formed at the surface of a roller-shaped aluminum substrate of which the surface has been machined has: a polishing step for mechanically polishing the surface of the roller-shaped aluminum substrate, of which the surface has been machined, at least until the average crystal grain size changes; and a minute bumpy structure formation step for anodizing the aluminum substrate after the polishing step and forming a minute bumpy structure. The anti-reflective article has a minute bumpy structure at the surface, and in the wavelength region of visible light, has a color difference (E*) to the origin represented in the L*a*b* color system and derived by means of formula (1) of no greater than 0.9, or a chroma (C*) determined by means of formula (2) of no greater than 0.7. E* = {(L*)2 + (a*)2 + (b*)2}1/2 …(1) C* = {(a*)2 + (b*)2}1/2 …(2)
