Dyeing, Printing, Color Management & Chemical Control
Converts oven length, line speed and curing temperature into the fixation dose actually delivered against a reference time-temperature point, separates the heat-up seconds that fix nothing, and returns the maximum line speed that still completes fixation.
Calculator
Dyeing, Printing, Color Management & Chemical Control
Corrects a recipe dose for the assayed strength of the lot actually in the store, and reports the depth shortfall an uncorrected recipe carries, the extra dye each batch consumes, the batches the stock will really make and the value of the strength deficit.
Calculator
Dyeing, Printing, Color Management & Chemical Control
Builds ink consumption from drop physics – resolution, pass count, coverage and drop volume – into millilitres and grams per square metre, then adds the purge and maintenance ink that never reaches the fabric and costs it per square metre.

Dyeing, Printing, Color Management & Chemical Control
Applies Henderson-Hasselbalch to the bicarbonate-carbonate step to give the carbonate fraction at a target pH, computes the Van Slyke buffer capacity the soda ash dose provides, and compares it against the acid released by dye hydrolysis and by the substrate.
Calculator
Specialized Chemistry & Advanced Dye Physics
Models the lotus effect on treated fabric: Cassie-Baxter apparent contact angle from solid fraction, the competing Wenzel state, droplet radius and adhesion force from contact angle hysteresis, and the surface tilt at which a drop rolls off.
Calculator
Specialized Chemistry & Advanced Dye Physics
Predicts colour-change apparel behaviour: activation rate from UV irradiance, colour developed and saturation reached over an exposure, the temperature-corrected reversal half-life, residual colour after moving indoors and time to clear below a visible threshold.
Calculator
Specialized Chemistry & Advanced Dye Physics
Calculates the mechanics of fragrance and phase-change microcapsules in fabric: single-capsule rupture force and pressure, the ratio against applied rubbing pressure, capsules burst per rub, payload released and the number of rubs to exhaust the garment.
Calculator
Specialized Chemistry & Advanced Dye Physics
Prevents optical brightener overdosing: CIE whiteness index at the current dose, the dose that maximises whiteness, the peak whiteness available, points of whiteness given away by overdosing, dose excess and reagent wasted per batch.
Calculator
Specialized Chemistry & Advanced Dye Physics
Calculates the chemistry for salt-free reactive dyeing of cotton: CHPTAC reagent and caustic charges for a batch, reagent actually fixed on the fibre, resulting zeta potential and degree of substitution, and the salt the route avoids.
