Chair of Textile Engineering
BSc (Applied Physics); PhD (Textile Engineering)
Carl has 12 years industrial experience in materials research employed by BISRA (Sheffield); Ruston and Paxman (Lincoln); Allen Clarke Research Centre (Caswell, Northants); Shirley Institute (now BTTG, Manchester); Turner and Newall (Rochdale) and RK Carbon Fibre and Composites (Stockport). Prior to his appointment to a chair at the University of Leeds, he was a senior lecturer in textile engineering at UMIST, where he was employed for 11 years. He is a member of the Management Board of the Technitex Faraday partnership and a member of the Techtextil Scientific Committee of Messe Frankfurt.
Recent work includes elucidation of the complex process-fibre interactions in the carding process in collaboration with Oxford’s OCIAM, which considers the fibre dynamics and aerodynamics of the short-staple card. High-speed photographic techniques using a 10w, 1nsec pulsed copper vapour laser and 40k fps video camera were employed to directly visualize the mechanisms in detail for the first time. Unconventional spinning system development includes work on a novel method of friction spinning; the use of air-jets for self-twist yarns; an investigation into a new patented disc-ring spinning process and the use of an electrostatic system for the assembly of core-yarns. Further research includes the structure-property relation of core-spun yarns; electrically conductive yarns; and multicomponent blend structures.
Natural Fibre Engineering and Biofibres
Modification of natural protein and cellulose fibres to produce alternative engineering materials is designed to extend the range of end-use applications for such natural materials in medicine and in the industrial engineering sectors. Research also includes melt and solution spinning of biopolymers for production of biodegradable / bioresorbable fibres. Previous work undertaken at Leeds has involved wet spinning of chitin, chitosan and alginate fibres. Current studies concern the production and characterisation of fibres from a variety of biopolymers. Work on ultra-fine filaments involves the formation of sub-micron filaments that are self-bulking or have high wickability.
Geosynthetic Fabric Engineering
Interest surrounds the engineering and construction of fibrous structures for inclusion in composite systems for rail track foundations to prevent erosion pumping. Other areas of research activity concerns geotextile protection systems for geomembrane containment structures, hydraulic properties of needle-punched nonwovens for concrete casting and structure-property relationships and performance of geosynthetic materials. In the building and construction field the biaxial properties of architectural textiles and stress cracking in HDPE are important developing areas of interest.
