Abstract:

In this paper a research work is described in which superfine wool powder was plasticised by glycerol and hot-pressed into a kind of thermoplastic film. SEM photos show that the powder is moulded into a smooth surface and is conglutinated into a continuous phase in the cross-section of the film. The glycerol content, moulding pressure, temperature and moulding time were changed in the moulding process. The sizes and thickness aw well as tensile strength, modulus, breaking elongation and breaking energy of the films were also tested to investigate the thermoplasticity and mechanical properties of the films. The best moulding techniques included a glycerol content of 30%, a moulding pressure of 5 MPa, a temperature of 160 °C and a moulding time of 5 minutes.
