Textiles vs Seaweed ?!?


Textiles… various applications


Textile materials are an enabling technology

Centexbel in a nutshell

Belgian research and technical centre:

Textiles and Plastics

Focus: new application areas, new materials

Membership organisation:

Belgian textile companies

Associated (international) member companies and

organisations

Staff:

Ca. 150 skilled and highly educated women & men


• Introduction

• At~Sea project

• Selection of results

• Conclusions & outlook


The concept

Advanced textiles to facilitate open sea cultivation of aquatic biomass, as a source for renewable energy, food/feed and biomaterials

Advanced textiles for open sea biomass cultivation (AT~SEA)


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


The team – truly multidisciplinary


• Introduction

• At~Sea project




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 turns textile into a flexible carrier offering specific functionalisations


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


Testing of textile substrates at three levels

• Testing and evaluation: Lab level

Tank level

At sea


Objective: study the cultivation of seaweed (Saccharina L.) on 11 different types of 1 m2 textile substrates

1m2 substrates at sea


Advanced textile substrates

Ireland Norway Scotland


Cultivation tests at sea using optimized 10 x 2 m2 advanced textile substrates


Coated textile storage bags


• Introduction

• At~Sea project




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
