Over the past 10 years, Dr. Rahman has patented a new fibre from waste biomass of canola plant (canola fibre) and established the properties of both canola and cattail fibres for automobile and aviation industries. The long-term research is to develop multiple harvest times for waste biomass fibres that will be suitable for specific applications including vegetable growing in a soilless environment using artificial intelligence software. His research also covers textile dyeing formulations in providing camouflage in the infrared regions for the military uniforms to blend into the soldier’s background.
Research title: Use of Python Computer Language to Predict Cattail Fibre Properties from Different Growth Stages (Collaborator: Dr. Nazim Cicek) Description: Existing analytical tools and mathematical modelling are not suitable to predict and rank the waste biomass fibres due to the larger variations in mechanical properties. In this research, we are using Python computer language programming to predict and ranked the properties of cattail fibre from various growth stages using the flax fibre properties as threshold values. Preliminary results suggest that mechanical properties of cattail fibres from the flower to matured stage development would be suitable for industrial applications. Therefore, it is possible that cattail plant could be harvested multiple times during a growth cycle instead of just one harvesting that is used for other biomass fibres. Research title: Treatment Responses of Cattail Fibres from Different Growth Stages (Collaborator: Dr. Danny Mann) Description: Fibre transformation to yarn and woven/knitted fabrics for industrial/apparel applications requires soft fibre. Extracted cattail fibres are stiff and not suitable for yarn transformation in ring or rotor machine. In this research, we are investigating the effects of enzymes on the cattail fibre softness from the various growth stages. Research title: Fabrication and process optimization of canola retting and separation machine Research team: Dr. Mashiur Rahman, Dr. Danny Mann; Dr. Wen Zhong, and Dr. Ying Chen. Currently, no mechanized process is available for retting and fibre separation from canola stalks. To conduct this research, we are fabricating a mechanical retting and separation machine to extract canola fibre from stalks. The retting and separation parameters of this mechanized machine will be optimized. Research title: Colour fastness of NIR dyed materials (Collaborator: Dr. Jitendra Paliwal) The NIR-dyed camouflaged defence fabric lost its performance after limited exposure to environments. This research is investigating the colour resistance of NIR-dyed materials to light, crocking and washing. The effects of pre-treatment on colour absorption and resistant is also being investigated.
Dr. Rahman does not have any graduate student opportunities available at this time.
