Objective
Objectives and content
This proposal aims to develop outlets for biodegradable
flax fibres in the European textile and automotive
sectors, on the one hand increasing its use in clothing
and hosiery by 15 % and on the other hand, in response to
international directives, contributing to the production
of completely recyclable vehicles.
Both of these goals necessitate optimisation of the
mechanical properties of flax fibres.
First, the textile industry would like flax fibres with
the suppleness and crease recovery of cotton (remained
angle on fabrics: 60 to 180 - yarn rigidity index: 34 to
5).
Second, the automotive field needs natural fibres with
tensile module comparable with glass or aranud fibres
(i.e. 60 to 90 Gpa).
These requirements can be met by flax fibres as they
exist within the plant but current chemical and
mechanical processes do not allow the mechanical
potential of native flax fibres to be transferred to the
finished product.
The assessment of knowledge in cell-wall biochemistry
and development of innovative enzymatic treatment will
allow flax fibres to be prepared in close to their native
state by selective hydrolysis of non-cellulosic polymers
in two ways:
physicochemical control of the endogenous enzymes of
the cell-wall and
use of specific mixtures of pure pectinase and
hemicellulases, excluding cellulose which are present in
commercially available preparations.
A fundamental requirement is to connect the technical
quality of the fibre (suppleness, strength, and
elasticity) with its technical structure to modify
efficiently the polymer-composite matrix.
An appropriate European assembly of centres of scientific
and technological excellence was necessary to reach this
threshold of basic knowledge in the most efficient way.
French partner 3 was selected for its historic competence
on cell-wall metabolism of flax. Belgian partner 5 is a
specialised group in industrial microbiology. Scottish
partner 4 is the leading academic laboratory using solid
-state NMR to link the mechanical properties of
biomaterials with their structure. The co-ordinator
(partner 1) and partner 2 are R&D organisations with
great experience of transferring scientific and technical
know-how to industry. Industrial partners 6, French
enzyme supplier, and 7, an Italian spinner that is world
leader in the linen sector, are interested in increasing
the use of biotechnological process to flax fibres.
The results will be capable of exploitation by enzyme
manufacturers, wet spinners and end users of flax
products. The industrial partners and R&D organisations
will be responsible for promoting the expected new
products to industry.
The long term objectives of this proposal derive from
areas 1.2.1 and 2.1.3 of the BRITE EURAM III program
taking into account, on one hand, the assessment of new
biotechnological processing methods and on the other
hand, the development and scaling up of innovative fibre
materials emerging from basic biochemistry and
enzymology.
