SEVENTH FRAMEWORK PROGRAMME FP7-NMP-2011-SME-5
Project nr: 280860
At~Sea Basics
• Contribute to large-scale offshore seaweed aquaculture in Europe
• Stimulate bioenergy production
• Dedicated advanced textiles development: – Growth: explore 2D (multi-layer) textiles vs 1D materials (ropes), maximise
attachment, promote growth
– Mooring: cables and connectors, flexible floatation tubes
– Storage/transport: flexible tanks
– Durability (!)
• Period: 2012-2015

Textile toolbox to promote attachment and growth
• Tuning of textile materials at various levels: – Basic material chemistry:
• PES, PP, PE, PLA, PVA, …
– Textile structures
– Textile finishing and coating

Textile structure
• Typical ‘structure’ of textile material:
• Fibre level: – Short or continuous
• Yarn level (‘thread’): –Mono/multifilament, tape,
– Textured, hairy/flat,…
• Fabric level: – Knitted, woven (mesh, scrim), nonwoven
– Tufted Carpet

Coating of growth substrates
• Motivation for coating: • Advanced algae adhesion
• Supply of nutrients
• Additional functionalities
• Evaluation of synthetic and bio-based products
• Various textures and chemistries

Textile conclusions
o Growth on 2D textiles is possible and beneficial: larger yield of biomass than state of the art rope based systems
o Textiles offer an extensive toolbox to optimise
the attachment and growth – the structure of the textile materials is key element
o New textile application area: first order for
subtrates; AT~SEA Technologies, a start-up coming from the project, will include textile companies
