The massive and frequent rate of textile industry closure in Nigeria is a disturbing phenomenon. The main objective of the study is to identify the determinants of decline in selected texctile manufacturing companies' in northern Nigeria. Cross sectional survey design was adopted in which relevant primary data was collected by means of questionnaire instrument. A sample of 384 was selected from the population of 7305 employees of four selected textiles manufacturing firms in northern Nigeria using stratified random sampling with proportionate sample size allocation. Data collected were analysed using factor analysis and three hypothesis were tested using multiple regression analysis. The results of multiple regression analysis show that only two factors acccount for declining of the textile industry. These are product quality and obsolete technology. While the remaining factor, foreign textile fabric does not significantly contribute to the decline. The study concludes that inadequate investment in modern textile technology led to production of low quality textile products which resulted in the collapse of textile industry in northern Nigeria. It recommeded investment in technological innovation and improvement to transform the industry.
