Abstract
An article, such as an article of footwear includes, a textile component. The textile component includes a yarn. The yarn includes a thermoplastic material and a blowing agent with an activation condition. Upon triggering the activation condition of the blowing agent, the blowing agent introduces a plurality of cavities, i.e. cells, into the thermoplastic material, creating a multicellular foam area of the textile.
Claims21
A textile, comprising:
- a first textile layer;
- a second textile layer;
- and
- a yarn that is inlaid between the first textile layer and the second textile layer,
- the yarn comprising:
- a core yarn;
- a multicellular foam comprising a thermoplastic material;
- wherein at least a portion of the multicellular foam is in direct contact with the core yarn and is exposed on a surface of the yarn;
- wherein the multicellular foam occupies a space between the first textile layer and the second textile layer and further extends through the first textile layer, forming a plurality of raised foam structures on an outer surface of the first textile layer;
- and
- wherein the plurality of raised foam structures are distinct in size and/or shape and/or spacing.
