Leafclock
A smart color-changing label that tells you when clothing should be replaced
Leafclock visually indicates fabric aging through gradual color change — helping brands and consumers know when it's time to replace, not guess.
The problem with textile replacement today
Most clothing is replaced based on habit, guesswork, or discomfort — not actual usage.
Overuse risks hygiene and comfort
Without clear signals, products are often used beyond their optimal lifespan, accumulating invisible bacteria and losing functionality.
Premature replacement causes waste
Guesswork leads to replacing items that still have useful life remaining, contributing to the massive global textile waste problem.
The disconnect in the lifecycle
Consumers lack usage data, and brands lack feedback loops. This gap between actual wear and replacement creates inefficiency for everyone.
Leafclock makes textile aging visible
Leafclock is a smart wash label that gradually changes color as garments are washed and worn.
The color shift serves as a simple, visual signal — indicating when a product has reached its optimal usage period.

The Complete Process
From first use to optimal replacement
Usage Starts
When a garment is first used, the Leafclock label appears in its initial color state.
At this stage, the textile is within its optimal usage period. The label remains stable and unchanged under normal early use. This gives both users and brands a clear starting point — a visible 'time zero' for the product's lifecycle.
Real-World Use Accumulates
As the garment is worn and washed, multiple everyday factors begin to take effect.
Washing and drying, light exposure, wear and friction, time and environmental aging — Leafclock responds to the combined impact of these real usage conditions, not to a single trigger or artificial signal.
Gradual Color Transition
Inside the label, Lifetracer bio-tracing technology drives a controlled molecular transformation.
Under repeated real-world use, the active molecular groups within the label gradually reorganize. This process causes the color to shift step by step — typically from yellow toward purple. The transition is progressive (not sudden), irreversible (not resettable), and visually intuitive (not abstract).
Replacement Point
The label signals that the textile is reaching the end of its recommended usage period.
Leafclock indicates when accumulated use makes replacement advisable — helping users avoid prolonged overuse. For brands, this creates a clear, consistent replacement logic that users can easily understand and trust.
Why Leafclock matters
For consumers
Clear replacement signals improve hygiene, comfort, and peace of mind — without asking users to remember or guess.
For brands
Leafclock adds functional value to everyday products, strengthens user trust, and creates a natural replacement rhythm that supports long-term customer loyalty.
For the planet
By making textile lifecycles visible, Leafclock helps reduce premature disposal and unnecessary overuse. Better replacement timing means less waste, fewer guess-based purchases, and more responsible use of textile resources.
