Abstract:
A process for improving the dyed appearance of a microdenier fabric, said microdenier fabric being comprised of conjugate filaments that are longitudinally separable into elementary filaments and having at least a first elementary filament material and a second elementary filament material, wherein said first filament material is susceptible to degradation by a degrading solution and said second filament material is substantially resistant to degradation by a degrading solution, said process comprising the steps of:(a) subjecting the microdenier fabric to the degrading solution for a determinate time and then rinsing, wherein the degrading solution degrades at least a portion of said first filament material; and (b) dyeing said second elementary filament material of the microdenier fabrics and wherein said first filament material is a polyamide selected from the group consisting of nylon 6, nylon 6.6, nylon 11, and nylon 6,10.
