Textiles that are capable of harvesting biomechanical energy via triboelectric effects interest for self-powered wearable electronics. Fabrication conformable and durable textiles with high outputs remains challenging. Here we propose a washable skin-touch-actuated textile-based nanogenerator mechanical from both voluntary involuntary body motions. Black phosphorus encapsulated hydrophobic cellulose oleoyl ester nanoparticles serves as synergetic electron-trapping coating, rendering textile long-term reliability triboelectricity regardless various extreme deformations, severe washing, extended environmental exposure. Considerably output (~250-880 V, ~0.48-1.1 µA cm
