Characterisation of vanillin and its application as carrier on commercial azo disperse dyes on woven polyester fabric

JOSEPH ODEY*, SALIU H. R, Abdulraheem Giwa

An extracted vanillin from Foster Clark vanilla flavour for the chemical substitution of toxic carriers used in aqueous dyeing of polyester fabrics was assessed. The extracted vanillin was used to compare the dyeing of a woven polyester fabric with two commercial dyes C.I Disperse Yellow 56, and C.I. Disperse Yellow 50. The vanillin carrier is used for dyeing at 3 % shade at boil, the dye uptak...

Determination of properties of Canarium schweinfurthii (Blackdate) seed shell reinforced composite

MAINA N. S*, ISA M. T, Adeniregun S

Crushed particles of canarium schweinfurthii (Blackdate) seed shells were used to reinforce general purpose unsaturated polyester and the properties were studied in this work. Particles of sizes 0.6mm, 1.18mm and 2.36mm with each particle size having a composition weight of 100g, 150g, 180g 200g and 220g respectively were used as reinforcement. The results showed that the composite produced fr...

Production of date-seed activated carbon for use in adsorption refrigeration application

ABDULKADIR M S*, Kulla D. M., PAM G Y

High energy requirement of vapour compression refrigeration systems necessitate the increasing need for more reliable, flexible and cost efficient cooling systems alternatives. Energy saving potential, Carbon emission reduction and waste heat utilization of adsorption refrigeration system could be exploited in this regard. Some of the setbacks that hinder adsorption refrigeration systems from r...

Correlation analysis of regulated and emerging Tri-Halomethane disinfection by-products and physico-chemical parameters of a community drinking water supply

Shaibu-Imodagbe E. M.*, MOHAMMAD Y S, OKUOFU C. A, UNYIMADU J. P, WILLIAMS A. B

Using the Pearson Correlation technique, this paper established significant linear relationship among pairs of analysed physic-chemical parameters with the determined regulated (regTHMsDBPs) and emerging (emergTHMsDBPs) Tri-halomethanes Disinfection By-Products in the drinking water produced by the Ahmadu Bello University water treatment plant. Using standard methods including the USEPA Method...

Effects of single super Phosphate and wood ash on biogas production using cow dung

Shaibu-Imodagbe E. M.*, MUSA R, Igboro S. B., Alfa M. I., Ishaq A.

This study was carried out to examine the catalytic effects of Single Super Phosphate (SSP) with Wood ash on the production of biogas from Cow Dung. The study was carried out in four identical reactors to enable variation of the catalyst combination (100gSSP/50gWoodash, 150gSSP/75gWoodash and 200gSSP/100gWoodash). The research showed that SSP and Wood ash could reduce the lag phase in anaerobi...

Electrical conductivity of Polyethylene Terephthalate (PET) fabric functionalized with multi-walled carbon nanotubes

ILIYA E. B*, R. Kotek, R.E. Gorga

Low aspect ratio pristine Multi-walled carbon nanotubes prepared by carbon vapour deposition  (CVD) were dispersed in Miranol, Cetyl pyridinium chloride and a 50:50 ratio mixture of them. They  were each applied on 100% PET fabric using classical polyester dyeing techniques (exhaust dyeing) as  well as cold padding by 3, 5-minute dip-dry techniques under controlled conditions. Exhaust dyeing  yiel...
