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

5

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

Problem of classic fluorocarbon treatments

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

Fabric

17

: 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

®

25

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)
