Spinning & Yarn
Works a yarn batch back to its oven-dry mass, computes the weight at a target regain and at the standard regain, and prices the moisture gained against the steam required to add it.
Calculator
Spinning & Yarn
Computes package speed and wind ratio at a given build diameter, finds the nearest low-order ratio that would produce ribboning, reports the distance to it as a risk figure, and gives the package diameter at which that pattern band actually falls.
Calculator
Spinning & Yarn
Converts a waxing add-on in grams per kilogram into wax consumed per hour and per package, the running life of a wax disc in hours and in kilograms of yarn, the cost per kilogram of yarn, and the friction coefficient the waxing is bought to achieve.
Calculator
Spinning & Yarn
Compares splice breaking force with the parent yarn as a retention percentage, reports the diameter ratio and bulk the splice adds, and derives the weakest splice a package is likely to contain from the splice strength variability.
Calculator
Spinning & Yarn
Converts siro strand spacing and convergence height into the convergence angle at the spinning triangle, reports the strand linear density and diameter, the spacing-to-diameter ratio, and the twist each strand receives about its own axis.
Calculator
Spinning & Yarn
Computes package volume as the conical frustum a cone actually is, gives the packing density from the wound mass, the yarn length it holds, the build thickness and cone taper angle, and the margin against the maximum density that package dyeing allows.
Calculator
Spinning & Yarn
Converts winding speed and yarn count into gross drum output, then subtracts the time lost to clearer cuts and package doffing to give the net production per drum and per machine, the splice count per package and the effective efficiency.
Calculator
Spinning & Yarn
Converts twist and yarn count into twist multiplier, surface twist angle and a twist-energy index, and predicts the snarls a doubled loop will form from the fraction of twist released – with the effect of steam setting taken out separately.
Calculator
Spinning & Yarn
Converts elastane supply count and core draft into the delivered core linear density inside the yarn, the core ratio by mass, the sheath that surrounds it, and the wall thickness of cover that separates the core from the yarn surface.
Calculator
Spinning & Yarn
Totals clearer cuts across the thin, thick, nep and foreign-fibre channels, converts them into cuts per hour, splices per package, production time lost and yarn wasted, and reports what share of the faults present is actually being removed.
