    摘要: Foamed articles including a foamed thermoplastic elastomeric material, methods of making the articles, and methods for manufacturing articles of footwear, apparel, and athletic equipment incorporating the articles are provided. One exemplary method for making a foamed article comprises placing an article comprising a foamable fibrous element and carbon dioxide in a vessel, the foamable fibrous element comprising a plurality of filaments, fibers, and/or yarns, wherein each member of the plurality comprises a foamable material; maintaining the vessel at a first pressure and first temperature at which the carbon dioxide is a liquid and carbon dioxide is soluble in the foamable material; optionally exposing the infused article to a second temperature and second pressure; and subjecting the article to a third pressure and third temperature at which the infused carbon dioxide phase transitions to a gas, thereby expanding the foamable material into a foamed material and forming the foamed article.

    摘要: Airsoles or bladders for articles of footwear comprising multi-layered films are provided herein. In one aspect, the airsoles or bladders comprise a first sheet and a second sheet, wherein a first side of the first sheet faces a second side of the second sheet, wherein the first sheet and the second sheet are bonded together to form an internal cavity in a space between the first side of the first sheet and the second side of the second sheet, forming a bladder capable of retaining a gas in the internal cavity at a pressure above atmospheric pressure, at atmospheric pressure, or below atmospheric pressure; and wherein each of the first sheet and the second sheet comprise a multi-layered film comprising: a core region comprising at least 20 gas-barrier layers and a plurality of elastomeric layers, wherein the gas-barrier layers alternate with the elastomeric layers.
