  • Publication number: 20210156056
    Abstract: The knitted textiles include a knitted structure including a plurality of hollow yarns. Each hollow yarn includes a yarn body and defines a yarn hole extending through the yarn body to allow expansion of the yarn body upon inflation of each hollow yarn through the yarn hole. The knitted structure is configured to transition from an unexpanded state to an expanded state in response to the inflation of the hollow yarns through the yarn hole. The knitted structure has a first porosity in the unexpanded state, and the knitted structure has a second porosity in the expanded state. The second porosity is less than the first porosity such that a visibility through the knitted structure is greater when the knitted structure is in the unexpanded state than when the knitted structure is in the expanded state.
