Determination of the Physico-Chemical Properties of Alkyd Resin Produced from Natural Shea Butter Oil

Abdulkadir Suleiman Abdulrahman^*, Mohammed K. Yakubu, Musa M. B.

Alkyd resin was prepared from shear butter oil (SBO) using the two step procedures; alcoholysis and polyesterification. The oil and alkyd resin were characterized and evaluated by standard methods, for their physico-chemical properties. The analysis showed that the alkyd resin based on Shea butter oil recorded average acid value of 15.2 (mgNaOH/g),...

Occupational Vat Dyeing Practices in the Kano Metropolis of Nigeria - Part 2: Operations of the dyers/dyeing enterprises in relation to industrial practices

Abdullahi S.^*, Nkeonye P. O., Mohammed K. Yakubu, Gumel S. M., Iliya, E.B.

The incorporation of synthetic blue vat dye and its derivatives in Nigeria since the 1930s reflected significant development within the dyeing industry where the dyers had to acquire new skills and the technical know-how in the use of this new line of ingredient. The aim of this paper is to assess the operations of occupational vat dyeing enterpris...

Occupational Vat Dyeing Practices in the Kano Metropolis of Nigeria - Part 3: Step-by- Step dyeing processes in relation to industrial practices

Abdullahi S.^*, Nkeonye P. O., Mohammed K. Yakubu, Gumel S. M., Iliya, E.B.

In traditional indigo dyeing it takes up to 45 days to ferment (reduce) the dye but with the advent of synthetic vat blue and the development of sodium dithionite the dyeing process becomes relatively short. Additionally, there is no standard process in vat dyeing. The aim of this paper is to assess the step-by-step vat dyeing processes in Kano met...

Fabrication and Characterization of Flambouyant Seed Particles-filled Unsaturated Polyester Composites

Umar, H. A^*, Ishiaku S. U., Mohammed K. Yakubu, Kogo A. A.

The research aimed at fabrication and characterization of Flambouyant Seed Particles (FSP) filled unsaturated polyester (UP) composites. The composites fabrication was achieved via hand layup with particle size of 100 µm at different filler loading of 2, 4, 6, 8, 10, 12, 14, 16, 18, 20 and 22 wt %. The composites were characterized by tensile prope...
