1. A method for forming an e-textile, the method comprising:
depositing a particle-free conductive ink on a textile substrate to form at least one pattern, wherein the particle-free conductive ink conformally coats fibers of the textile; and
curing the particle-free conductive ink in the at least one pattern to form at least one conductive pattern,
wherein during depositing the particle-free conductive ink, the textile substrate is heated to a temperature of about 30° C. to about 90° C.,
wherein the at least one conductive pattern exhibits an ink bleed of less than 0.5 mm and a resistance of less than 10Ω/□,
wherein the ink bleed is measured as a distance from an intended border of a printed trace that the particle-free conductive ink may extend.
