Abstract
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 metropolis in relation to industrial practices. This crossectional descriptive study was conducted among 1387 dyers together with focus group discussion, observation and measurement. Data were analysed by descriptive statistics (frequency and average) using statistical package for the social sciences (SPSS) software. Results showed that the dyeing process is entirely manual and the dyers can apply the dye using different procedures with some similarities, modifications, and differences in relation to industrial practices. The dyeing venture may not live to its full potential due to shortcomings related to the quality of the dyed materials. In order to improve on the dyeing processes, it is recommended for related departments in academic institutions to collaborate with the major dyeing enterprises in terms of research/innovation and placement of students under Students Industrial Work Experience Scheme (SIWES). Furthermore, government should introduce tie-dye among entrepreneurship courses offered in tertiary institutions to enable interested students acquire chemistry background of the dyeing processes.
