Advanced Spinning, Texturizing & Twisting
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.
Calculator
Advanced Spinning, Texturizing & Twisting
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.
Calculator
Advanced Spinning, Texturizing & Twisting
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.
Calculator
Advanced Spinning, Texturizing & Twisting
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.
Calculator
Advanced Spinning, Texturizing & Twisting
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.
Calculator
Advanced Spinning, Texturizing & Twisting
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.
