Functional, luxury, and niche textiles such as conductive, flame-retardant, antimicrobial, and high- fashion surfaces. This section explains practical decision criteria, typical test methods, and failure modes that matter in real production. Readers get checklists, calculation steps, and case examples connecting specifications to cost, reliability, and compliance. Links map core concepts to upstream inputs and downstream processes so choices remain consistent across sourcing, manufacturing, and end-use performance. Each article includes definitions, diagrams where helpful, and plain-language notes to help newcomers ramp quickly while giving experienced professionals the depth needed to troubleshoot and optimize. Standards references are cited with context, and whenever trade-offs exist, we make them explicit so you can defend decisions.
Works back from a towel’s finished size and nameplate weight to the yarn that has to be bought for it. Terry shrinks hard in finishing, so areal weight rises without yarn being added and a quote built on the finished figure is short from the start. Reports loom-state weight, yarn per towel and per dozen, the cost of both, and how many kilograms of yarn are bought for each kilogram of towel that is sold.
Calculator
Turns basket diameter and spin speed into g-force, converts a residual moisture figure into the water and the energy the dryer inherits, and sets the extractor’s own electricity against the drying energy it avoids.
Calculator
Turns tuft density, pile height and yarn count into pile yarn consumption and face weight in both metric and imperial, reports pile density and yarn cost per square metre, and converts a BCF line output in kilograms per hour into square metres of carpet a day.
Calculator
Scores how many of the twelve elements in Annex III of the Ecodesign for Sustainable Products Regulation you can already produce a document for. Annex III is the menu a future delegated act draws a product passport from; no textile act exists yet, so this reports what you hold, not whether you comply.
Calculator
Runs a recycled and virgin blend through separate process losses, compares the content claimed on input with the content the output actually carries, and solves the recycled input a target content requires after both losses.
Calculator
Models microfibre shedding as a declining series across launderings, summing lifetime release, splitting it between what filtration captures and what reaches the environment, and scaling both to an annual production volume.
Calculator
Adds the three sludge streams a textile effluent plant generates – removed suspended solids, coagulant floc and biological yield on removed COD – converts dry solids to wet cake at the achieved dryness, and prices disposal per day and per tonne of fabric.
Calculator
Applies Napier choked-orifice flow to a failed-open steam trap to give the steam it passes, scales it across the failed population, and converts the loss into annual steam tonnage, cost, boiler fuel, carbon and the payback on a trap survey.
Calculator
Converts inlet and outlet ADMI colour readings into removal efficiency and the margin against a discharge limit, sizes the coagulant and decolourising agent needed, and reports the chemical cost per cubic metre and the removal each unit of dose buys.
Calculator
Sizes a capacitor bank from the tangent difference between present and target power factor, reports the apparent power removed from the supply, the distribution loss reduction that follows, and the demand charge and penalty the correction stops paying.
