Que peuvent apporter les nouvelles

technologies textiles dans le domaine

de la gestion de l’eau ?

Julien PAYEN – Directeur Projets UP-tex

Introduction

TEXTILE MATERIAL ?

Today : Textile and Water

Veolia Hydrotech Filter Filters using woven

polyester mesh (10 to 1000 micron)

Veolia 3FM Filters using polyamide

fibers from 40 to 100 microns

WASTE WATER TREATMENT

New textiles solutions ?

Fine fibers generate pores and surface area

Jongchul Park, Finetex EnE, Filtrex 2010

Micron Fibers Sub-Micron Fibers

Nanofibers

Special Shape Fibers

P84™

4DG™

Specific surface area vs. Denier per

filament

Procon™

Allasso ®

Objective :

Increase specific

surface area

Special Shape Fibers :

– P84™ (Inspec)

– Procon™ (Toyobo)

– 4DG™ (FIT)

– Allasso ® (Allasso Industries)

Textiles Associations

Nonwoven with variable porosity: “gradient composite” Combined Filtration

Porosity gradient filter

Functional Textiles

Hydrophobicity/Oleophobicity with Vacuum Plasma

Heavy Metals Particles catched by Cyclodextrins

Conductive textiles or sensors textiles

Cyclodextrins Cage molecules for active compound

Water Textile Sensor (ENSAIT)

Nanofics Hydrophobic Textiles (Europlasma)

Consortium :

FUI Program : 2011 - 2015 Budget : 3 393 k€

Objectives : - Graft biobased polymers onto geotextiles to interact with heavy metals ions

R&D Project at UP-tex

Innovative Methods for Mud

Dehydratation

FUI Program : 2014 - 2018

Budget : 1 493 k€

Consortium :
