Abstract

Films, fibers, filaments, yarns and textiles including thermoplastic elastomeric compositions are described, as are methods of making the films, fibers, filaments, yarns and textiles. These films, fibers, filaments, yarns and textiles can be used to make articles of apparel, footwear, and sporting equipment. When thermoformed, the thermoplastic elastomeric compositions can impart abrasion resistance, traction, and other advantageous properties to the articles. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

First claim

wherein the thermoformed network of yarns is the thermoformed product of a first textile comprising a first network of yarns including a first coated yarn comprising the first core yarn and a first coating, the first coating comprising the first polymeric composition, the first core yarn comprising a second polymeric composition, and wherein, in the thermoformed network, the first polymeric composition consolidating the thermoformed network of yarns is the re-flowed and re-solidified product of the first polymeric composition of the first coating of the first coated yarn;
wherein, in the first coated yarn, the first thermoplastic composition has a first melting temperature greater than about 110 degrees Celsius and less than about 190 degrees Celsius, the second polymeric composition of the core yarn has a second deformation temperature, and the second deformation temperature is at least 50 degrees Celsius greater than the first melting temperature of the first polymeric composition;
wherein the thermoformed network of the textile defines at least a portion of a surface of the upper configured to be externally-facing when the upper is part of a finished article of footwear; and
wherein the at least a portion of the surface of the upper defined by the thermoformed network has a total surface area of at least 1 square centimeter, and within the total surface area, at least 15 to 100 percent of the total surface area comprises the first polymeric composition.
