The little naughty boy who used to have to change his diaper every hour can now wear XX pull-up pants and play for three hours without stopping. Aiming at the characteristics of increased single urine volume of toddlers (up to 100ml/time), we have improved the core structure of diapers: Upper layer: 1.2mm instant absorbent cotton transplanted from physiological pants, 0.8 seconds to lock liquid. Middle layer: X-shaped diversion groove diverts urine to 8 water storage tanks. Bottom layer: 0.01mm ultra-thin breathable membrane, humidity evaporation speed increased by 40%. Laboratory data show that even if you encounter the "parabolic urine posture" unique to boys, it can be completely absorbed within 3 seconds without reverse osmosis. Elastic waist that can "breathe independently" Traditional pull-up pants often have waist marks when babies squat. The 3D honeycomb waist we developed: The horizontal stretch rate reaches 220%, which exceeds the growt…
