1 Introduction
Heat and mass transmission from the human body to the environment or vice-versa
takes place through clothing which serves as a second skin. Thermo-physiological
properties of textiles are related to the thermal properties, air permeability and moisture management properties along with the drying ability of the textiles. Moisture
management properties of textiles are influenced by several fibres, yarn and fabric
constructional variables. Plating is an innovative knitted fabric production technique
to obtain bi-layered fabrics. Plated knit structures are characterized by distinct yet
integrated inner and outer layers. The flexibility in the selection of contrastingly
different fibre and yarn constituents in the two layers of plated fabrics make them
suitable and versatile for applications like intimate wears, sportswear, active wear
etc. The main elements of two-layered plated knitted structures are:
Inner (next to skin) layer: This layer is in direct skin contact and consists of
a conductive and diffusive hydrophobic component which helps in removal and
transportation of sweat to the outer layer.
Outer (exposed to environment) layer: This layer is in contact with the environment
and consists of absorptive hydrophilic components which provide a large area for
sweat absorption and evaporation to the outside environment [1, 2]. Fibre parameters,
process parameters and yarn production technologies are reported to change the
yarn structure and the associated fabric properties. Ring and rotor spun yarns vary
widely in their structures which contribute to the entirely different properties of the
two yarns. Ring-spun yarn has an ideal cylindrical helical structure with the same
number of turns per unit length in each helix, uniform specific volume and maximum
