🧵 Knitting Calculation Engine
GSM + Fabric Type
→ Everything Automated
Yarn count, loop length, machine gauge, K/T/M pattern, production rate — no manual calculation needed.

Pick an exact color to drive a true-to-life dyed-fabric preview. Leave empty to use only the Color Shade mode below.
Dia + Gauge + RPM will give exact production rates (kg/hr, shift, day).
Target Width → system recommends the exact single optimal Dia. Leave blank for the standard economical machine.

Yarn Specification (grade, spinning system & form)
Quality hierarchy: Supima/Giza (ELS) › Combed › Carded › Open-End › Recycled.
The engine returns strength (RKM/CSP), evenness (U%), spinnability check & price index.
Spinning system also drives spirality. Sources: Klein, Uster Statistics 2018.
Real count-based prices from SM Spinning Mills (2 May 2026). Add-ons per price-list footnotes:
White +$0.10 cotton/+$0.05 blend · Organic +$0.60 (GOTS/OCS) · Slub +$0.30 · Ecovero +$0.45 · At-Sight −$0.05.
Finishing & Quality (boosts shrinkage accuracy)
Finishing route is the #1 driver of residual shrinkage — compacted ≈ half of greige.
Based on Munden relaxation theory · tested per AATCC 135 / AATCC 179.
Woven Construction (pre-filled from the selected quality)
Fill in width and length to get the yarn requirement in kilograms, split warp and weft.
Leave the sett and counts as they are to use the quality the book prints.
Warp Knit (optional)
