Abstract: The present invention provides a novel down-like cotton material which is bulky, light-weight, excellent in washing resistance, heat-retaining property and heat insulation property and provides volume feeling, without odor from animals. The down-like cotton material 1 of the present invention is formed as a cotton-like long fiber, in which filaments of an axial fiber and a float each composed of a polyester raw yarn are united by air entangling in air flow to be entangled, connected and integrated to have a down ball-like mass in an aligned form, and the diameter of the down ball-like mass is 1.0 to 3.5 cm and down ball-like masses are continually aligned at an interval of up to about 10 cm or less in a length direction of the axial fiber.

Abstract: The present invention discloses a gel mat and a method for manufacturing the same. The purpose thereof is to provide a gel mat which features simple manufacturing process, low cost, ease of use, high reliability, and freedom from possible damage in case of being pierced or depressed with a pressure, and a method for manufacturing the same. The gel mat includes a hermetically sealed bag which is constituted by two layers of a film material, the bag being packed with gel flakes. Said method for manufacturing a gel mat comprises the steps of preparation of material, bag making, monomer solution pouring, heating for solidification, and inspection and packaging in this order. The present invention adopts a gel instead of water, which is conventionally used, for producing a flake gel mat the external surfaces of which are inside a bag; the gel is a colloid obtained by polymerizing the organic matter; approx. 70% of the gel is constituted by water; and thus the gel mat has an extremely good endothermic performance.
