Properties of chemically modified Baobab pod/Sisal Fibre reinforced Low Density Polyethylene Hybrid Composite

ISA M. T^*, Umar Shehu, Aderemi B. O., Bello T. K., Audu H. I., Umar Shittu Muhammad, ATTA A. Y

The present study determined the effect of sodium hydroxide (NaOH) treatment on the properties of baobab pod/sisal fibres reinforced low-density polyethylene (LDPE) hybrid composites. Used to treatment the fibres, were different concentrations of NaOH 2 -10 wt% at 2 wt% interval. The hybrid composites were compounded using two roll mills machine an...

Research Article Vol. 7, Issue 1

Synthesis and characterisation of Azo dyes derived from Naphthalen-2-ol and their washfastness properties on cotton, wool and nylon fabrics

Abdulraheem Giwa^*, Mela A. C., Umar Shittu Muhammad

A series of azo dyes was synthesised by coupling reaction of napththalen-2-ol with diazotized 4- sodiumphenolate, 4-Nitrophenylazo and 4-Chlorophenylazo respectively, as diazo components. The characterization of the dyes was carried out by GC/MS analysis. The solubility of dyes in the visible absorption spectra was also determined. The dyeing perfo...
