YarnTwist

Calculate yarn twist multiplier and predict tensile strength

Manufacturing AIFree

YarnTwist computes optimal twist multiplier from fiber staple length, denier, and target yarn count using empirical twist-strength relationships for cotton, wool, and synthetic fibers. The tool predicts yarn tensile strength, elongation, and hairiness from twist level and fiber property inputs using Hearle's idealized helical model with corrections for fiber migration. Twist balance calculations for plied yarns ensure torque neutrality to prevent fabric skew in knitted constructions.
