Good washability, one of the major challenges for wide commercial adoption of e-textile products, is essential for e-textiles to survive intense mechanical deformations and water invasion of washing cycles used during their life cycles. The wash stability of the MOFbased e-textiles was assessed following a British Standard (BS EN ISO 105C06 A1S)(ISO, 2010) to evaluate their performance at 10 simulated home-laundry washing cycles. Before testing, a translucent, thin, and stretchable PU-based encapsulant was applied to protect MOFprinted wearable e-textiles. The purpose was to keep the printed layer attached to textiles but covered and protected. The printed e-textile patterns start to lose electrical conductivity just after one washing cycle. The electrical resistance of washed e-textiles was found to be ~93 MΩ cm -1 after the first washing cycle, which further continued to increase after each wash cycle (Supporting information 8, Figure ). After 10 wash cycles, the resistance was found ~181 MΩ cm -1 , which is only 2 times the initial resistance.
