Spinning & Yarn
Converts air-jet or vortex delivery speed and yarn count into production per position and per machine, then totals the compressed-air demand, the compressor power behind it, and the energy and cost that air adds to every kilogram of yarn.
Calculator
Spinning & Yarn
Converts mean single-end strength and its coefficient of variation into strength percentiles, the expected weakest place over a stated length of yarn, and the safety factor against running tension measured on both the mean and that weakest place.
Calculator
Spinning & Yarn
Links rotor speed and delivery speed to twist per metre and twist multiplier, computes rotor peripheral speed and the centrifugal acceleration at the rotor groove, checks rotor diameter against fibre length, and reports production per rotor and per machine.
Calculator
Spinning & Yarn
Derives spinning tension from traveller mass, ring diameter and spindle speed through the centrifugal balance, compares it with the yarn strength as a tension ratio, and converts a breakage rate per thousand spindle hours into piecings, lost spindle time and efficiency.
Calculator
Spinning & Yarn
Derives ring-frame total and main draft from roving and yarn linear density, checks the front control distance and back zone setting against effective fibre length, and computes the limit irregularity from the number of fibres in the yarn cross-section.
Calculator
Spinning & Yarn
Converts per-spindle compacting airflow and suction pressure into fan shaft power through the fan and motor efficiencies, then reports specific power per spindle, energy per kilogram of yarn, and the annual energy and cost of running the compacting system.
Calculator
Advanced Spinning, Texturizing & Twisting
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.
Calculator
Advanced Spinning, Texturizing & Twisting
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.
Calculator
Advanced Spinning, Texturizing & Twisting
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.
Calculator
Advanced Spinning, Texturizing & Twisting
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.
