The Technology
Behind Leafclock
Leafclock is built on a bio-responsive color-changing system designed to make textile replacement visible, intuitive, and reliable. Instead of measuring hygiene directly, Leafclock tracks real-world usage and aging factors that lead to textile degradation. Through gradual color change, it helps users recognize when a product has reached the end of its optimal lifecycle — and should be replaced.
This makes textile management simpler for consumers, and more predictable for brands.
What Leafclock Responds To
What Leafclock Responds To
Multiple Everyday Factors Drive the Color Transition
Washing & Drying
Repeated washing and drying activate the gradual release and transformation of active groups within the label, driving the color shift.
Light Exposure
Daily exposure to light accelerates the aging process and contributes to visible color evolution.
Wear & Friction
Friction from wearing and handling supports molecular restructuring during normal use.
Time & Environmental Aging
Long-term exposure to air, moisture, and external contamination continuously influences the label's response.
Together, these factors create a realistic and reliable indication of textile lifecycle progression.
Progressive Color Transition Process
How the Color
Change Works
At the core of Leafclock is our Lifetracer bio-tracing technology.
The label contains multi-target, environment-responsive nanomaterials. Under repeated washing, light exposure, wear, and aging, the active molecular groups gradually reorganize and transform.
This process results in a controlled, irreversible color transition — typically from yellow to purple — that reflects accumulated usage rather than a single event.
Because the change is progressive, users can visually recognize early, mid, and end stages of a product's lifecycle instead of relying on memory or guesswork.

Usage Models
Leafclock is not limited to a fixed usage cycle.
The color-change speed and transition curve can be adjusted to match different product categories and usage scenarios. Brands may choose different models based on fabric type, wear intensity, or recommended replacement timelines.
For example, one product may require a shorter lifecycle reminder, while another may be designed for extended use. Leafclock allows these differences to be reflected visually — without adding complexity for the end user.
This flexibility makes the technology suitable for a wide range of textile applications.
Different Models, Same System
Designed for Real Products
Built for Daily Wear and Repeated Washing
Leafclock labels are developed for daily wear and repeated washing. They are soft, skin-friendly, and securely integrated into garments. The labels maintain their structure and appearance through extensive washing cycles and do not affect comfort or fabric performance.
All materials are selected with safety, durability, and long-term usability in mind, ensuring the label remains reliable throughout the product's intended lifespan.
Wash Durability Test
" Textiles are often overused simply because there is no visible signal telling people when to replace them.
Leafclock introduces a simple visual language that helps reduce overuse, improve hygiene habits, and support more responsible consumption. By encouraging timely replacement instead of premature disposal or excessive use, the technology helps balance comfort, health, and sustainability.
For brands, this means clearer product value, stronger user trust, and a more thoughtful relationship between products and people.
