Why this concept
Replacement of traditional fluorocarbon, for stain release
properties
Fluoro carbons are under environmental pressure
C8 (well known problem)
C6 (starts to have also a bad image)
Market trend: eg M&S
C6 (short chain PFC) mandatory from 1st January 2013 on all new
developments for stain/oil repellent product
Eliminate use of any C8 in flow lines by end 2013 – switch to C6 - or non-
PFC finishes
50% reduction in PFC use by end 2013 – achieved by switch of ‘Water
Repellent’ product to non-PFC technologies
M&S committed to total PFC elimination in textiles by 1st July 2016 – through
substitution to non-PFC technologies

Traditional fluorocarbons
Liquid
Fluoro Chains
Fabric
Classic fluorocarbon chains for textile are based on linear chains of
6 or 8 carbons (C6 - C8)
Fluorocarbon chains need an orientation in order to be efficient
The orientation occurs at high temperatures
Fabric
6
First challenge traditional fluorocarbons
High temperature in production
Shrinkage sensitive fibers
Discoloration…
Need for tumble drying or ironing after washing
Never rub on a stain…
7
Rubbing a Stain:
Liquid repellent: Primary protection against stains
If stain penetrates through the Fluorocarbon chains
Stain will be trapped in

Rubbing a Stain:
Water can not access the fabrics
Stains will not be removable

First challenge
10
Hydrophobic and oleophobic finishes:
Good to avoid liquid penetration
Bad to release « trapped-in » stains
Hydrophilic finishes:
Bad to avoid liquid penetration
Good to release « trapped-in » stains
Electrofluorination
Uses electrolysis to replace hydrogen atoms in a molecule by fluorine
atoms to create an 8 unit chain containing just carbon and fluorine
PFOS (perfluoro octane sulfonate) is being produced
Telomerization
Joining mini polymers by joining single units together in chains.
Average chain length is 8 but chains can be from 4 to 14 units
PFOA (perfluoro octanoic acid) is being produced
Second challenge: environmental pressure
11
Concern around PFOA
Is toxic and carcinogen in animals
Is persistent in the environment
Has been detected in the blood of general populations where it has been
associated with infertility
In people with higher exposures, PFOA exposure is associated with birth defects,
increased cancer rates, and changes to lipid levels, the immune system and liver
effects
PFOA has been detected in industrial waste, stain resistant carpets, house dust,
water and food
12
Concern around PFOS
Man-made fluorosurfactant
Global pollutant, found back in animals who have never been exposed to
fluorocarbons
Added to the Stockholm Convention on Persistent Organic Pollutants by the Fourth
Conference of Parties in May 2009.
Is suspected of compromising the immune system of wildlife and a small segment of
highly exposed people globally
Might cause reduced birth weights in humans, a finding arising from animal studies
Was used by Dupont 3M under the Scotchguard brand, stopped production in May
2000
13
Effects from C8 not yet proven through scientific research
Industry is reacting merely on pressure from media
Manufacturers are changing from C8 to C6 chemistry
Has in some cases a tremendous impact on performance standards
Second challenge: environmental pressure
14
Market is very focused on water and oil repellent
Once stain goes through a stain repellent finish, it is very hard to remove
In most cases stain release is needed
Especially with the trend of low washing temperatures
Consumer education will be needed
Third challenge: the market standards
15
Use of new patented technology focussed on stain release
Focus on sustainability: No PFOA/PFOS
Educate the consumer market that release is more important than repellent
Differentiate by market segment (different needs)
: the opportunity ®
16
Traditional fluorocarbon: C6-C8 chemistry
Mono-functional group: one link to the surface
Limited level of wash durability
Heat needed for the orientation of the fluorocarbon (curing)
High temperature curing might damage fiber types
After washing, tumble drying or ironing needed for reactivation
Harsh polymer structure
Handle might impart softness of the textile
Not abrasion resistant
C8 Chemistry under media pressure due to PFOA/PFOS

: the technology ®
18
Bi-functional group: 2 links to the surface
Enhanced adhesion
Enhanced wash durability
No Linear chains
No curing is needed, drying at 130°C
Lower temperatures during textile production, decreases shade change or other
damages caused in processing conditions
No reactivation necessary after washing
Flexible polymer structure
Contains fluoro, but does not contain PFOA or PFOS
Totally different production process
No C8, C6 or C4

: sustainable technology
products are:
PFOA/PFOS free
Formaldehyde free
APEO free
No high curing needed
Makes washings at lower temperatures more efficient

: abrasion resistant
products have a flexible polymer structure
Strong adhesion to surfaces
Enhanced abrasion resistance during wearing and rubbing
Breathable to vapor
Increased wear comfort
The strong film formation and adhesion
of explains the high durability
and performance. It also shows that the
chemistry is fundamentally different than
classic fluorocarbon products (C8, C6)
Classic fluorocarbon shows the poor
scratch resistance Classic fluorocarbon

Does not require high curing temperature (creating a harsh
handle) whereby the aspect of delicate textiles will be
maintained.
Due to the flexible polymer structure

: stain release test procedure
Stain Release test methods are very customer specific
Each test is different depending on project, stain to remove, type of textile.
devan developed an own internal method
Fabric is being stained with:
Ketchup
Mustard
Red wine
Coffee
After 15 min and 24h the wet stain is being wiped off with a wet tissue
Stain removed with sponge and water or in washing machine at 40°C
The stain is being compared towards an untreated

Testing results 1: Blood comparing to C6 Left stain: untouched (Mattress Ticking – 100%PES)
Middle stain: cleaning with wet sponge after 15 minutes
Right stain: cleaning with wet sponge after 24 hours (eco release is better than C6)
