Assessment of dyeing and some fastness properties of nanocrystalline cellulose extracted from corn cob

BUKHARI M. M*, SALEH YUSUF MAIGARI, ATTA A. Y, Mohammed K. Yakubu

The dyeing of nanocrystalline (NCC) cellulose powder extracted from corn cob (Saleh, 2015) was carried out using Reactive (Procion Violet H-3R), Disperse (Foron YellowS.E 2GL) and Direct (Solophenyl Yellow) dyes. The percentage exhaustion in each case was calculated to determine which of the dyes exhausted best. The fastness of the dyed NCC powd...

Synthesis of active methylene azo disperse dyes based on 4-Amino-3-Nitrobenzaldehyde as diazo component and their application on polyester and Nylon 6.6 fabric

SALISU A*, Bello K. A., Mohammed K. Yakubu

Active methylene azo disperse dyes were synthesized and characterized. A good percentage yield of each of the dyes were obtained in the range of 58-82 %. The dyes have well defined melting points in the range of 270 – 404 C. The visible absorption spectra of the dyes showed that the dyes absorbed maximally within the visible region of the elect...

Synthesis and characterization of chitosan from locust

ALANI O. A*, Mohammed K. Yakubu, BUKHARI M. M, GADIMOH S.

Chitin was isolated from locust using a standard procedure as described in literature with slight modifications. Chitosan was then synthesized from the isolated chitin by treatment with 50% concentration of NaOH, the degree of the deacetylation obtained was 64.4% using Potentiometer Titration method. Both chitin and chitosan ash content and mois...
