Abstract: Methods, systems, and devices for changing cross-sectional sizes and/or shapes of flat braided sutures and the resulting constructs are disclosed. The flat braided sutures can have a textile first cross-sectional shape that can be changed to a textile second cross-sectional shape. The systems can have a heater and a die. The flat braided sutures can be movable through the heater and the die. When the flat braided sutures are in the heater, the flat braided sutures can be heatable from a textile first temperature to a textile second temperature greater than the textile first temperature. When the flat braided sutures are at the textile second temperature, the textile first cross-sectional shape can be changeable to the textile second cross-sectional shape.

Abstract: A welding process may be configured to convert a substrate comprised of short staple fibers into a welded substrate having significantly increased strength as compared to the raw substrate. When applied to a one-dimensional substrate, such as a yam, the welding process may also reduce the diameter of the welded substrate compared to that of the raw substrate. Additionally, the welding process may be configured to impart superior color properties to the welded substrate compared to the color properties of the raw substrate, which superior color properties may be very pronounced when performing a welding process on a raw substrate comprised of colored and/or dyed recycled fibers.
