- Blended Yarn Commercial & Invoice Weight Calculator Converts an as-received blended consignment to its commercial invoice weight using the mass-weighted official regain of the two fibres, showing oven-dry weight, the water actually present and how far the billing weight differs from the shipped weight. Commercial Invoice Weight kg
- Crocking (Rubbing) Colourfastness Assessment Averages dry and wet crocking grades across three specimens, compares each against its own buyer specification, and reports the dry-to-wet gap that distinguishes unfixed surface dye from genuine poor fastness. Binding Margin grades
- Elmendorf Tear Strength & Energy Calculator (ASTM D1424) Converts an Elmendorf pendulum scale reading into tear force per ply in gram-force and newtons, the tear index normalised to fabric weight, the work absorbed over the standard tear length and the margin inside the valid scale window. Tear Force per Ply gf
- Fabric UPF (Ultraviolet Protection Factor) Predictor Models fabric ultraviolet protection from cover factor, fibre transmittance and dye absorbance: UV transmission, the UPF it implies, the labelled UPF after standard rounding, and the ceiling that open area alone imposes. Predicted UPF
- Grab Tensile Strength Statistics Calculator (ASTM D5034) Reduces five grab tensile specimens to reportable statistics: mean breaking force, sample standard deviation, coefficient of variation, range, the 95% lower confidence limit and the margin over a specified minimum. Mean Breaking Force N
- Martindale Abrasion Weight Loss Extrapolator Extrapolates Martindale abrasion mass loss from a measured interval: loss rate per thousand cycles, projected loss at a target cycle count, and the cycles the specimen will take to reach a defined failure threshold. Cycles to Failure Threshold no.
- MVTR & Evaporative Resistance (Ret) Calculator Converts a cup-test mass loss into moisture vapour transmission rate per day and per hour, the evaporative heat flux it represents, and the evaporative resistance Ret that breathability specifications are written against. MVTR g/m²/24h
- Wind-Degraded Thermal Resistance (Tog & Clo) Matrix Degrades a still-air tog rating for wind speed and fabric air permeability, returning effective tog, clo and Rct in wind, the percentage of insulation lost and the wind penetration factor for extreme weather layering. Effective Thermal Resistance tog
