Abstract

The theory of viscoelasticity in textile assemblies reported in part I is extended to blends. The effects of ageing and annealing on the stress relaxation processes in a blended textile are separated according to the demarcation provided by the glass transition temperature of the constituent fibres in the blend. The effect on the mechanical properties of the different fibres can be represented by horizontally shifting the stress relaxation curves in the logarithmic time scale. The time shift factor is different for each fibre at the same reference state, making a single time shift factor impossible for blends. A study of the interaction between fibre blend components of wool/polyester fabrics shows that they are influenced by differences in stress relaxation behaviour of the blend constituents, blend composition, and fabric weave construction. Annealing improves the viscoelastic properties of wool/polyester blended fabrics. For parts I and II see abstracts 1987/4398 and 1987/5037.
