Abstract

Exact description of yarn structure using mathematical formulation leads to complete identification of yarn properties and hence projection of fabric properties. The present work is an attempt trial to study the yarn geometry to find a suitable exponent of twist factor. The logic of analysis is based on the well-known helical model of yarn introducing the variability of raw material and production technology.
Different cotton yarns were used to justify the results of the theoretical analysis. The effect of the suggested and other known exponents on the behavior of the strength – twist multiplier curves were compared. Also the values of the constant (k) used in determination of yarn diameter is discussed according to the suggested exponent.
