Abstract:
1. A device comprising: a nonwoven textile substrate having microfibers formed therein and further having a matrix at least partially impregnated therein and at least partially surrounding at least a portion of the microfibers, the microfibers including exposed surface area; a non-azo disperse dye disposed in the exposed surface area of the microfibers, wherein the device is produced by a process comprising the steps of: (a) dyeing the nonwoven textile substrate with a non-azo disperse dye and (b) scouring the dyed nonwoven textile substrate by a process comprising the steps of: (i) immersing the dyed nonwoven textile substrate in an aqueous bath comprising at least one alkali material, (ii) increasing the temperature of the aqueous bath to a first temperature, (iii) adding a reductive scouring material to the aqueous bath at the first temperature, (iv) scouring the dyed nonwoven textile substrate in the aqueous bath at the first temperature, (v) decreasing the temperature of the aqueous bath to a second temperature, and (vi) rinsing the dyed nonwoven textile substrate.
