摘要:
A dyed substrate having at least one dyed surface. At least one dye solution is disposed across at least a portion of the surface in combination with a migration promoting composition and/or a migration limiting composition. The migration promoting composition and/or migration limiting composition adjusts the migration of at least a portion of the dye solution across the substrate in a controlled manner. Dye migration may be arrested by the application of RF (radio frequency) energy as a step in dye fixation. A process for forming the dyed substrate is also provided.

摘要:
The present invention is a mat system, having two embodiments, each of which is capable of removing the dirt from the soles of mat users' shoes. The mats are comprised of a plurality of individual tiles (10) that interlock along complementary edge portions (20, 22). One embodiment of the mat system is a thermoplastic elastomer (TPE) mat that has a plurality of projections (40) that remove dirt. The second embodiment, also having a TPE structure and a lesser number of projections (40), features several carpet strips that provide additional dirt removal means. Once the individual tiles are connected, the outermost complementary edges may be covered by a plurality of border strips that provide an aesthetically pleasing and functionally necessary finished edge to the mat. The border strips are secured to one another by a mechanical clip that is also described.
