- What Twist Multiplier to Spin At Premium Balances the production a ring frame gives up for every turn of twist against the end breakage it buys back, quality by quality, and holds the answer above the strength the yarn is actually sold on. Reports which qualities are worth twisting harder, which softer, which are being spun below their own specification, and how many extra breaks a tenth of twist may cost before it stops paying. What Setting the Twist Properly Is Worth cost/yr
- Comber Noil Extraction Optimizer Runs a short-fibre mass balance across the comber to show what a chosen noil percentage actually buys: residual short fibre in the combed sliver, removal efficiency, machine output and the raw-material cost per kilogram of combed sliver. Residual Short Fibre in Sliver %
- Cop Building Motion & Traverse Speed Optimizer Derives the ring rail traverse speed needed to build a cop at a chosen coil pitch, from spindle speed, twist level, chase length and ring diameter, with the coils per layer, yarn laid per layer and chase time. Ring Rail Traverse Speed mm/min
- DREF Friction Spinning Core-to-Sheath Ratio Tool Splits a target core-spun technical yarn into its core and sheath linear densities, derives the draft each feed sliver must run at, and returns production per position for DREF friction spinning. Sheath Draft ×
- DTY Crimp Rigidity & Contraction Estimator Converts the three skein lengths of the DIN 53840 crimp test into crimp contraction, crimp rigidity, crimp stability and bulk factor for draw-texturized filament yarn, with linear density per filament. Crimp Rigidity %
- False Twist Texturizing Surge Speed Calculator Finds the yarn speed at which a friction false-twist unit loses twist stability, from disc diameter, disc rpm and the working disc-to-yarn speed ratio, with the inserted twist level, yarn diameter and throughput at the limit. Surge Speed m/min
- Hairiness to Singeing Intensity & Gas Demand Matcher Converts the required drop in Uster hairiness index into singeing energy per square metre, burner heat load, gas flow per burner and gas consumed per kilogram of fabric, at a given cloth speed, width and areal weight. Gas Flow m³/h
- Melange Yarn Fibre Blending Ratio Calculator Converts a target melange shade percentage into the dyed and white fibre weights to actually issue, grossing each component up by its own process loss, and checks the recipe against the integer sliver doublings available in the draw frame creel. Dyed Fibre to Issue kg
- Spindle Wharve, Tape Speed & Slippage Calculator Calculates tape surface speed and the theoretical spindle speed from drive cylinder and wharve diameters, then quantifies belt slip against a measured spindle speed and converts that loss into missing twist per metre. Tape Slip %
- Two-for-One Twister Production & Power Calculator Calculates TFO twisting output per spindle and per machine per shift from spindle speed, twist level and efficiency, then converts connected spindle power into kWh per kilogram and energy cost per kilogram of twisted yarn. Machine Production kg/shift
- Vortex (Air-Jet) Spinning Delivery Speed & Draft Modeler Models a vortex spinning frame: total draft from sliver to yarn count, production per position and per machine at a given delivery speed and efficiency, plus compressed-air consumption and specific air per kilogram of yarn. Machine Production kg/h
