Profiled and Hollow Polyester Fibres in Nonwoven Fabrics and Their Heat Transfer

Abstract

The macromorphological structure of profiled and hollow fibres permits their application in different composite systems using their specific properties. The physical properties of profiled and hollow fibres change under the affect of the geometry of the developed fibre surfaces, increased unit surface of the fibres and the presence of hollows inside the fibres. Such fibres considerably change the transport properties of fibre textile systems and composite materials. The paper deals with the effect of geometric parameters of profiled and hollow fibres on thermal management during heat transfers through a textile layer via conduction and radiation.
