A device (e.g., an article of athletic gear) comprising a post-molded expandable component, which is a part of the device that is configured to be expanded or has been expanded after being molded. This may allow the post-molded expandable component to have enhanced characteristics (e.g., be more shock-absorbent, lighter, etc.), to be cost-effectively manufactured (e.g., by using less material and/or making it in various sizes), and/or to be customized for a user (e.g., by custom-fitting it to the user).

The present disclosure provides: a biodegradable nonwoven fabric for thermoforming, the biodegradable nonwoven fabric being composed of a fiber of a polylactic acid-based polymer, and having a basis weight of 20-300 g/m.sup.2, preferably, a biodegradable nonwoven fabric characterized by being composed of a long fiber of a polylactic acid polymer, having an MD-direction elongation of 50% or more at 120° C., and having an MD-direction dimensional change rate of ±4% or less at 80-140° C. as determined by thermomechanical analysis; a method for producing a molded body by using said biodegradable nonwoven fabric; and a method for molding a biodegradable beverage extraction container, the method being characterized in that the molded body has an MD-direction elongation change rate of 4% or less, as determined by thermomechanical analysis (TMA) under a load of 0.05 N/2 mm at 30-100° C.

A strip-shape softened resin sheet (S) which is continuously extruded from a molten resin extruder is cut to a unit resin sheet and a press molded product is manufactured by press-molding the unit resin sheet in a press-molding machine 20. Prior to press-molding the unit resin sheet (U) by the press-molding machine, the unit resin sheet (U) is heated by a heating machine 16. The heating machine 16 comprises a first heating furnace 84 and a second heating furnace 86. The first heating furnace 84 includes a series of heaters 84-3 and 84-4 whose heat source is infrared ray in a far-infrared region and the second heating furnace 86 includes a series of heaters 86-3 and 86-4 whose heat source is the infrared ray in a middle-infrared region. In the first furnace 84, the unit resin sheet (U) is continuously conveyed with a low velocity and is gradually heated by the far-infrared ray up to temperature which is slightly lower than the temperature which is suitable for press-molding the unit resin sheet (U). In the second furnace 86, the unit resin sheet (U) is stopped and is rapidly heated by the middle-infrared ray. By efficiently heating the unit resin sheet (U), a cycle time can be shortened and the production speed can be improved.
