Influence of Enzyme and Chemical Pretreatment Processes on the Colours of Banana Fibres

Colour is an important property of textile fibres. The colour of mechanically extracted fibre affects the colour of the fibre textiles products. The focus of this investigation is to compare the colour of different pre-treatment process for banana fibre and evaluate the suitability of the banana fibre treatment methods for dyeing process. Experimental research strategies were used to investigate the colour properties. Ambun (AAA/Cavendish) banana variety was selected for this research study. Treated and mechanically extracted banana fibre samples colour measurement was performed by using a data colour machine 600 spectrophotometer and assessed using CIELAB colour values. This experiment was conducted to the suitability of the banana fibre extraction methods for dyeing process. Results indicate that there is a significant change in colour due to the different treatments achieved higher AE* values. Treatment of enzyme and 6% H
