Nationally and internationally colour, fashion and textile industries face major opportunities and challenges that can only be unlocked by high-quality research and innovation.
Major drivers include the need for sustainable development and viable circular economies, the increasing impacts of global population growth, and an ageing population. Globally, countless consumer, healthcare and industrial products contain textile materials, or depend on colour to ensure their success.
LITAC creates new understanding and develops technology-driven solutions, working directly with end-users and harnessing multi-disciplinary academic research expertise from across the University. LITAC’s core research expertise includes textile technology, textile and fashion design, polymer science, and colour science and technology. Activities are supported by some of the most extensively equipped research facilities in the world, benefitting from a further ~£9M of additional investment in recent years.
The group’s research focuses on technical developments in the manufacturing, performance and characterisation of fibres, yarns and fabrics, including knitted, woven and nonwoven structures, as well as the modification of textile materials through deployment of innovative textile chemistry. Innovative recycling and reuse technologies are also being explored as part of efforts to implement viable circular economies. Textile technology research is key to both developing the next generation of sustainable textile products, that minimise impacts from cradle-to-grave, as well to the performance of a multitude of healthcare, consumer and industrial products containing textiles, on which society depends.
Projects in textile technology address the science and engineering of clothing and technical textiles, with a view to improving product performance and reducing environmental impacts. Clothing-related research includes developing textile materials designed to stop fibrous microplastic release at source and exploring innovative laundry treatments to promote fabric longevity. Research in technical textiles is a broad field, covering applications as diverse as, medical devices for healthcare, filter media and composites. Developing underpinning structure-property relationships and balancing complex property requirements in the development of innovative textile materials are key areas of activity.
Research in textile technology research is supported by extensively equipped laboratories for experimental work on fibre extrusion, yarn spinning, weaving, knitting and nonwoven fabric manufacturing, as well as dyeing and finishing. Extensive analytical, testing and characterisation facilities are also available on site, enabling textile materials and their properties to be comprehensively studied and quantified. These resources are further strengthened by extensively equipped specialist facilities such as:
- 3D Weaving Innovation Centre
- Clothworkers’ Centre for Textile Materials Innovation for Healthcare
- Future Fashion Factory (FFF)
The research has led to numerous innovative commercial products, as well as the launch of successful University of Leeds spinout companies that specialise in the areas of: nonwovens, low water conserving textile processes, and extraction of plant-based chemistry for multiple consumer products.
Research in polymer chemistry covers the design, synthesis and characterisation of monomers and macromolecules, in order to generate functional polymers and polymer-containing materials on the basis of targeted applicability and application. Particular interests are in the design and development of novel monomers for use in controlled polymerisation reactions to yield highly multifunctional polymers, novel photocatalytic materials, renewable fibre forming polymer materials, biodegradable materials, fibres made from recycled materials, multifunctional fibres, flame retardant materials for extreme environments and polymeric membranes.
There is also significant work in the areas of:
- Biomaterials: synthesis of multifunctional hydrogels and fibres, filament-based soft robotics, diagnostic and theranostic polymer materials with tunable properties for applications in woundcare, regenerative medicine and other medical devices.
- Surface coatings: polymer synthesis and conversion, rheological properties, migration phenomena, ageing effects, controlled delivery, appropriate mechanical and dynamic priorities, and end of life strategies (waste handling).
- Printed electronics: design and synthesis of high-performance semi-conductor molecules, formulation of conductive and dielectric inks, development of point-of-care medical diagnostic sensors, development of ultrathin and high-performance lithium-ion batteries.
Textile and fashion design
The group researches multiple aspects of the textile and fashion sector, from fashion products to packaging, branding and communications. This includes work in areas that influence sustainability, end-to-end across the sector, including fashion and textile design, technical design, pattern cutting, garment production, design production management, accessories, illustration, fashion and textile merchandising, marketing, journalism, photography, styling, image consultation, trend analysis, historical dress and textiles, fashion and textile archives. The main aim is to promote and provide expert knowledge through research enquiry into all design areas of fashion and textiles with particular specialisms in garment technology, sustainability, fashion history, culture and ethics.
Recent research activities include, understanding and addressing modern slavery in the fashion and textile industry, encouraging public engagement with textile waste management and developing high quality digital communication tools, including creating virtual 3D garment draping as a service. The Group’s research is supported by unique resources, such as:
