E-TEXTILES FABRICATED USING PARTICLE-FREE CONDUCTIVE INKS

Described herein are methods for forming e-textiles, wherein the methods include printing a particle-free conductive ink on a textile substrate, and curing the textile substrate to produce a conductive pattern thereon. The printing may include inkjet printing and may produce a printed pattern which...

Beschreibung
Zusammenfassung:	Described herein are methods for forming e-textiles, wherein the methods include printing a particle-free conductive ink on a textile substrate, and curing the textile substrate to produce a conductive pattern thereon. The printing may include inkjet printing and may produce a printed pattern which exhibits an ink bleed of less than 0.5 mm, such as less than 0.2 mm. During printing, the textile substrate may be heated to a temperature of 30° C. to 90° C. before and during the printing process. The fabric substrate may be cured using heat and/or light to produce a conductive pattern having a sheet resistance of less than 10 Ω/□, or even less than 1 Ω/□.
