- What to Do With a Batch That Comes Out Off Shade Premium Works out the first move on an off-shade batch by looking forward to the last attempt the cloth will survive rather than at the cost of this one. Prices topping up, stripping and re-dyeing, submitting the shade for approval and downgrading against each other, band by band, and reports what the habit of always topping up first is costing where the shade is worst. What the Right First Move Is Worth cost/yr
- Boiler Steam Requirement for Dyeing Batches Calculates the thermal energy and saturated steam needed to raise a dye bath and its fabric load to process temperature, and the heating time a given boiler capacity will take to get there. Steam per Batch kg
- Cellulase Biopolishing: Activity, Weight Loss & Strength Converts an enzyme dose and declared activity into units per kilogram of fabric, derates them for temperature and pH away from optimum, and returns the saturating weight loss, the strength it costs and the time a target weight loss actually needs. Weight Loss %
- Continuous Dyeing Range Dosing Pump Rate Calculator Synchronises chemical dosing to fabric speed on a continuous dyeing range, converting line speed, width, fabric weight and wet pick-up into litres per hour of liquor and the pump setting in millilitres per minute. Liquor Demand L/h
- Dye Exhaustion & Fixation Percentage Calculator Separates dye exhaustion from true fixation using bath concentrations before dyeing, after dyeing and after soaping, exposing how much dye was absorbed but never covalently fixed. Exhaustion %
- Dyeing Recipe & Bulk Dosing Calculator Scales a laboratory dyeing recipe to bulk, converting shade percentage on weight of fabric into kilograms of dye and grams per litre of salt and alkali into batch quantities, with a correction for commercial dye strength. Dye Required kg
- Fabric pH Neutralization Acid Dosing Calculator Calculates the volume of acid needed to bring an alkaline bath down to a target pH after scouring or reactive dyeing, from bath volume, current pH and acid normality. Acid Required L
- Lab Dip & Shade Matching Adjustment Tool Corrects an off-shade lab dip by scaling dye concentration against the measured colour strength from a spectrophotometer, and reports the Delta E position against the agreed commercial tolerance. Corrected Concentration % owf
- Liquor Ratio (MLR) & Water Consumption Calculator Converts batch weight and material to liquor ratio into dye bath volume, then totals the water drawn across the dye bath and every rinse fill, with the cost per batch and per kilogram of fabric. Dye Bath Volume L
- Mercerisation Baume, NaOH Concentration & Barium Activity Number Converts a mercerising liquor between degrees Baume, specific gravity, per cent sodium hydroxide by weight and grams per litre, computes the caustic carried on the goods at a given wet pickup, and turns AATCC 89 barium hydroxide titration figures into the barium activity number. Sodium Hydroxide % w/w
- Pad-Batch Dyeing Pick-up Calculator Determines wet pick-up on a padder from dry and wet sample weights, then converts it into liquor and dye required for the full batch and the resulting depth of shade on weight of fabric. Wet Pick-up %
- Rotary Printing Repeat Size to Screen Matcher Checks whether a design repeat divides exactly into a rotary screen circumference, and returns the adjusted repeat size that will print seamlessly along with the distortion that adjustment introduces. Seamless Repeat Size mm
- Scouring Weight Loss & Peroxide Bleaching Bath Recipe Calculates cotton scouring weight loss from non-cellulosic content and scouring efficiency, then builds the hydrogen peroxide bleach bath: bath volume from the liquor ratio, litres of commercial peroxide at its actual strength and density, available active oxygen, caustic and stabiliser charges, and the alkali to peroxide ratio. Total Preparation Weight Loss %
- Screen Printing Colour Paste Consumption Estimator Estimates print paste consumption for a run from fabric area, design coverage and the paste pick-up of the screen mesh, giving kilograms per colour, per metre and for the whole order. Total Paste Required kg
