- Which Finishing Line Each Quality Should Run On Premium Loads a book of fabric across finishing lines that are not the same as each other, by working out what a metre of each quality actually costs on each machine once width, chambers, hourly cost and the seconds that machine makes are all counted. Returns the metres to put on each line, what an extra ten hours on each is worth, and what loading by speed instead of by cost is costing. What Loading It Properly Is Worth cost
- Antimicrobial Log Reduction & Durable Dose Converts recovered colony counts into percentage and log reduction against the specification, shows the count a target log reduction actually demands, and carries the applied dose through wash retention to the initial loading a durable claim requires. Log Reduction log
- Dot Lamination Adhesive Add-On & Bonded Area Computes adhesive add-on from engraved dot geometry: cavity volume, volume per square metre, wet and dry add-on after transfer efficiency and solids, the share of area actually bonded, the finished laminate weight and the adhesive consumed per thousand metres. Dry Adhesive Add-On g/m2
- Finishing Trough Changeover: Purge Volume & Time Compares drain-and-refill cleaning against a continuous flow-through purge for a finishing trough, returning the rinse cycles a carryover limit needs, the volume and time each route costs and the water the better one saves. Drain-and-Refill Cycles Needed nos
- FR Add-On Durability & Initial Loading Required Treats flame retardant loss as geometric decay across launderings and returns the add-on surviving at the target wash count, the wash at which it crosses the effective minimum, the half-life of the finish and the initial loading a durable claim actually requires. Add-On at Target Wash Count % owf
- Heat-Setting Time-Temperature Equivalence & Line Speed Trade Converts a validated heat-setting reference of temperature and dwell into the equivalent dwell at any other temperature through the Arrhenius rate ratio, then into the line speed and production that temperature allows, with the degrees needed to buy a ten per cent speed change.

- Pad-Dry-Cure Thermal Load & Pick-Up Sensitivity Builds the full heat balance for a pad-dry-cure line: sensible heat in the carried water, latent heat of evaporation and sensible heat in the cloth to cure temperature, then the burner rating, the specific energy and what five points off the mangle would save. Burner Duty Required kW
- Raising Drum Kinematics & Pile Action Balance Turns drum and roller speeds into the surface speeds that matter, the slip between wire points and cloth for both pile and counter-pile rollers, the balance between them, and the relative travel a pass puts through the fabric. Pile Slip Speed m/min
