Functional Properties of Integrated Knitted Structures

Abstract

Integrated double-layer knitted structures have been constructed and knitted, using various raw materials and employing various combinations of fibres in absorption (face) and diffusion (back) layers of the fabric. The same raw material used for the absorptive layer has been used for crossing points (so called »suction wicks«) between the layers. The influence of the raw material used and construction characteristics of the knitted structure on moisture regain, moisture transportability, permeability to water vapour and air, wetting rate and drying rate has been investigated. Synthetic fibres in diffusion layer significantly increase permeability and moisture transport rate, while the type of the fibres used has a significant impact on these properties. Some functional characteristics (for example wetting rate and air permeability) are also dependent upon the combination of fibres used in individual layers, as well as upon construction characteristics of the knitted structure.
