Abrégé

Disclosed is a three-dimensional microfiber extrudate structure and a process of forming a three-dimensional microfiber extrudate structure. The three-dimensional microfiber extrudate structure includes a matrix having a three-dimensional geometry wherein the three-dimensional geometry is a visco-elastic relaxation state of a preform introduced to a medium.

Abrégé

A fiber having a non-uniform composition is disclosed. The fiber includes a first domain having a first composition and a second domain having a second composition different from the first composition. The fiber includes an interphase region intermediate the first and second domains that includes a blend of the first and second compositions to provide a gradual transition from the first domain composition to the second domain composition. A method for making such fibers is also disclosed.

Abrégé

Disclosed is a spinneret and a method of spinning. The spinneret includes a first pore configured for extruding a first component of a multi-component fiber, a second pore configured for extruding a second component of the multi-component fiber, and a thermal insulator positioned between the first pore and the second pore and configured for preventing heat from the first component from damaging the second component. The first component and the second component have incompatible thermal resistance.

Abrégé

A method for producing covert markers is disclosed. The method includes providing a substrate, providing a radiation source, providing a mask intermediate the substrate and the radiation source and transmitting radiation from the radiation source through the mask onto the substrate to ablate a portion of the substrate thereby creating the covert marker. The covert markers can be applied to genuine articles for later authentication.
