About

From research article to a usable tool

DyeFlow Lab is a university research prototype. It makes a finite-bath, two-region dye-transport model explorable for textile engineers, dye-house staff and students.

Project background

Why DyeFlow Lab exists

Exhaust dyeing is a coupled transport problem. Dye leaves a finite bath, crosses the textile surface, diffuses through liquid-filled pores and exchanges with the fiber material. The underlying research develops a mass-conserving mathematical model of this process.

This website makes that model usable without programming. Every calculation runs in the visitor’s browser, and the results are explained in ordinary language.

Research status

What has and has not been shown

  • Verified: the numerical solver conserves mass and agrees with an independent Python reference solver.
  • Not yet shown: agreement with measured dyeing experiments for any specific fabric and dye.
  • Therefore: all outputs are labeled research simulations.

Privacy by design

Your batch data stays with you

  • No accounts, cookies, analytics or tracking scripts.
  • Simulation inputs are never sent to a server. Recent runs are stored only in your own browser so you can compare them, and can be cleared at any time.
  • The site is static and hosted on Cloudflare Pages over HTTPS.
Principles

How we keep the science honest

No invented numbers

The app never derives transport coefficients from fabric type, dye name, temperature or pH.

Conservation first

Every run reports its mass-balance residual, so arithmetic errors cannot hide.
