- Raw Material Cover & Price Exposure Sheet Premium Sets a mill's cotton position against the yarn it has already sold at a fixed price, which is the only comparison that says whether the mill is exposed. Separates tonnage secured from price secured, converts firm yarn sales into the cotton they require at the stated realisation, and prices a movement against the gap in either direction. Exposure t
- The Cheapest Bale Laydown That Still Meets the Specification Premium Solves the laydown as the blending problem it is: the cheapest combination of the lots actually on the floor that still meets every line of the cotton specification, inside the availability of each lot and a mixing discipline that keeps any one of them from dominating. Then prices each line of the specification separately, so the mill knows which one is costing it money and which five are free. What the Specification Costs a Laydown cost
- The Grams Above Nominal That Nobody Pays You For Premium Prices the distance between the GSM a fabric is sold at and the GSM a mill actually has to aim at, because running on nominal puts half the rolls under the lower limit. Every gram of that distance is yarn given away on every square metre of every order, and it is invisible because the cloth passes. Reports what it costs a year, the lowest aim that still holds the light-roll rate you will accept, and how much of the giveaway is bought back by aiming better against how much needs the variation reduced. What the Giveaway Costs cost/yr
- Bale Density, Press Duty & Container Fill Turns bale mass and dimensions into density and compression ratio, gives the height a target density needs, sizes the press force and ram pressure from a compaction pressure, and reports how many bales a container holds and whether it cubes out or weighs out. Bale Density kg/m3
- Bale Laydown Constraint Window & Minimum Bale Count Works out how many bales a laydown needs so mix-to-mix variation stays inside tolerance: the standard error of the laydown mean for micronaire and strength, the bale count each property demands on its own, which one binds, and the sigma margin left at the planned count. Minimum Bales Required bales
- Bale Moisture & Net-Mass Normalizer Separates gross, tare, net and oven-dry mass for a received bale, restores the dry fibre to commercial mass at the standard regain, and prices the difference against the invoiced weight for the bale and for the whole lot. Commercial Mass per Bale kg
- Cotton Contamination & Colour Grade Risk Scorer Combines stickiness, bark, polypropylene, seed coat fragments and colour grade into one lot risk score, separates out the share contributed by polypropylene, and prices the expected downgrade against lot value. Composite Contamination Risk /100
- Fibre & Fabric Conditioning Time to Moisture Equilibrium Estimates the time a textile specimen needs to reach moisture equilibrium in a standard atmosphere, using capacity-limited Fickian diffusion through the fibre assembly: porosity and sorption capacity set the effective diffusivity, specimen half-thickness sets the time constant, and the required tolerance sets how many time constants must pass. Time to Reach Tolerance h
- Fibre Blend Homogeneity Index Across Process Stages Tracks blend variation from bale laydown through chute feed and sliver to yarn, reports how much variance each stage removed, tests the measured blend ratio against target for statistical significance, and flags any stage that added variation. Blend Homogeneity Index %
- Fibre Length Distribution & Short Fibre Content Fits a log-normal length distribution to a measured mean and coefficient of variation, then derives upper half mean length, uniformity index, median length, short fibre content on both the by-number and by-weight bases, and the fraction above a long-fibre threshold. Upper Half Mean Length mm
- Fineness & Maturity Calibration Validity Converter Converts a micronaire reading to standard fineness through an explicitly stated linear calibration model, then reports how far outside the calibration range the reading sits, inflates the reported uncertainty by that extrapolation, and checks maturity against the model validity floor. Extrapolation Beyond Calibration %
- HVI Replicate & Outlier Checker Separates three causes of a suspect fibre result: the Grubbs statistic for an abnormal specimen against the ceiling the replicate count allows, check-cotton bias for instrument drift, and the replicate spread against the method repeatability standard deviation. Grubbs Statistic G σ
- Laboratory Sample Chain-of-Custody, Load & Turnaround Converts daily lot intake into samples, tests and technician hours, compares the load against real bench capacity, and reports turnaround including the conditioning period, the custody records generated and the retained sample mass an ISO/IEC 17025 laboratory must store. Technician Utilisation %
- Staple Cut-Length, Crimp Contraction & Tow-to-Staple Yield Computes crimp contraction from crimp frequency and amplitude by integrating the arc length of the crimp wave, converts an extended cut length into the crimped length actually measured, and reports staples per gram, crimps per staple, filament count in the tow and cut-line production. Crimp Contraction %
- Statistical Sampling Plan, OC Curve & Average Outgoing Quality Sizes an attribute sampling plan from lot size and inspection level using the ISO 2859-1 code letter table, then computes the full operating characteristic: acceptance probability at the AQL, producer's risk, the quality level the plan rejects nine times in ten, average outgoing quality and the inspection load. Sample Size units
- Trash Particle Size Class Removal & Selectivity Splits blowroom and card cleaning efficiency by particle size class — dust, medium trash and large trash — then prices the good fibre thrown out with it, returning the selectivity ratio of trash removed to lint lost. Overall Particle Removal %
