Cocona Competitive Landscape

A comparison of Cocona fabrics against other fabrics

Cocona Technology

• Cocona™ is a patented technology• Cocona™ is made with activated carbon• The activated carbon structure is micro-porous.

• This vast micro-pore structure differentiates the performance of Cocona™ fabrics from competitors

• Cocona™ fabrics adsorb & disperse moisture, odor and UV light

Natural

• Cocona™ is derived from naturally occurring coconut shells

• Patagonia has accepted the Cocona™ product as being, sustainable, sourced as a by-product, and is free of hazardous chemicals

• Cocona™ reduces the carbon foot profile of Cocona™ containing garments

Patented Technology

• US Patent 7247374 Issued July 24, 2007

• World wide coverage• Patent claims all active particles• Patent claims a process to keep the particles active during processing

• All activated carbons are covered in the patents

• All surface active materials are covered in the patent

Active Particles

• Defined: particles which interact physically or chemically with the surrounding environment

• Physical interactions are adsorbance

• Chemical interactions are catalyst, chemical changes

• For active particles to work they need to be exposed to the environment, they can not be covered or coated.

Certification - Verification

• Determine active particle is active– OAV Certification (ASTM D5742)– Butane adsorbance

• Determine fabric wets– Water Drop (AATCC 79)– FlashDryTM Test– Wicking Height

• UV Protection– AATCC 183

Bamboo Products

• Bamboo Activated Carbon– activated carbon product– how they keep the carbon

active is unknown– has different pore size

compared to coconut activated carbon

– refresh temperature is higher than coconut activated carbon

– is not anti-bacterial/microbial

– absorbs ammonia

• Bamboo Fiber– fibers made from

Bamboo wood– viscose product– has limited anti-

bacterial properties– poor wetting– poor wicking– poor drying– is not an activate

carbon

Adsorbance

• Reversible process• Exothermic process (releases heat)• Temperature dependant process• Size dependant process

Odor Test Methods

• Cocona Inc uses ASTM D 5742– Butane adsorbance– determines if the process worked properly– used for certification purposes

• Other Methods– Ammonia removal test (SGS Detective Tube

Method)– Acetic Acid removal test (SGS Detective

Tube Method)– Anti-bacterial test (AATCC 6538)– Scent-Lok test– Artificial nose

Quick Drying Mechanism

• Experimental data shows Cocona fabrics dry faster compared to the same non-Cocona fabric (Dryer testing, 0.2mL water drop test, hang drying)

• Known facts:– Activated carbon has a huge surface area (1000 m2/g)

– Adsorbance is an exothermic process (releases heat)

– Cocona fabrics have exposed activated carbon surface area and adsorb butane

Quick Drying

• The largest part of Apparel's carbon footprint is the washing & drying (82% of the life time energy consumption)

• Manufacturing, disposal, & packaging makes up remaining 18%

• Cocona™ fabrics reduce the amount of drying by 50 to 1000 % in comparison to current competitive products

• When blending Cocona™ with cotton similar results occur versus other poly/cotton blends

Carbon Footprint

Independent studies show that most of the energy consumption involved with apparel pertains to after a garment is manufactured. Washing and drying consume far more energy than the actual manufacturing process.

FlashDryTM

• FlashDryTM fabrics are defined by drying in 120 seconds using the FlashDry™ testing method

• This corresponds to a 10 minute dryer dry time for a Polo Shirt

• FlashDryTM fabrics will be branded accordingly in TexBase

Cooling Effect

• Evaporating perspiration is the body’s cooling mechanism

• Cocona™ has a large amount of surface area because of the porous surface area of particles on the surface of the yarn

• Not only wicks faster but dries 50% faster

• Wear testers emphasize a perceptible “cool effect”

• Additionally Dry in winter (fleece) = warm

UV Protection

• “It is estimated that over 1 million

new cases of skin cancer occur

annually in USA.” MedicineNet inc.

• UVA and UVB rays absorbed naturally

• Up to 50 UPF (Ultraviolet Protection

Factor)

• No chemical treatments

• Will not wear out or wash off
