Abstract


In Nigeria, Low-Density Polyethylene (LDPE) is widely used for making water sachets and other plastic wraps. After use, non-biodegradable LDPE constitute waste disposal problem and environmental pollution. In the same vain cow hair fibres from tanneries pose disposal challenge. Composites were prepared from the waste materials by melt-mixing and hot compression moulding techniques. In order to increase the adhesion, chemical treatment of the fibres was done with 0.2 M H2O2, 0.2 M KOH, and 0.2 M NaOH. Composites of untreated and treated cow hair fibres were prepared with 0 to 50 wt% fibre loading at intervals of 10 wt% and their physical and mechanical properties were evaluated. Results obtained showed significant improvement in the mechanical properties of the composites filled with the chemically treated cow hair fibres.
