1. The first LLIN made of polypropylene
2. Effectiveness independently validated beyond 35 washes
3. Improved textile strength validated in laboratory tests
4. Soft to touch and pliable
5. Improved efficacy against Culex mosquitoes
6. Reduced flammability compared to polyethylene and polyester nets
7. ISO certified for environment impact

The full efficacy of LifeNet against Anopheles mosquitoes is restored within few hours after washing. The surface of LifeNet is recharged with active ingredient from the reservoir within the fibers, due to its slow release system.

Report of the 14th WHOPES Working Group Meeting.
Textile testing overview
page 9 • •
An extensive range of textile tests to support our performance claims
page 10 • •
• LifeNet has undergone a broad range of textile tests• A broad range of tests gives a better picture of
performance under real-life conditions • Bursting strength (ISO 19338-1:1998)• Dimensional stability • Slow Nail Test• Dynamic nail test• Abrasion resistance • Tensile strip tests• Thermal aging• Soiling• Dynamic bagging• Stonewashing
Bursting strength
page 11 • •
A standard method which assesses the strength of a piece of net in ‘all directions’
LifeNet was shown to be the strongest and both panels and seams had consistent strength.
Dimensional Stability
page 12 • •
Assesses the change in dimensions of a piece of netting after five washes at 40 degrees centigrade
LifeNet showed the least degree of dimensional change after this washing regime
Slow Nail Test
page 13 • •
LifeNet showed the best balance of strength in both directions
Pieces of net are slowly pulled against a fixed nail (in both directions of row and column).
Dynamic Nail Test
page 14 • •
Pieces of net are rapidly pulled against a fixed nail (in both directions of row and column).
LifeNet showed the best balance of strength in both directions
Textile testing results overview
page 15 • •
The multifilament polypropylene fiber construction of LifeNet results in a net with stronger mechanical properties than polyester and polyethylene nets.
Stronger nets are less likely to develop holes and damage during use – effectively providing longer protection under field conditions
The influence of net characteristics on behavioural attitudes towards net usage
page 16 • •
LifeNet favours high end-user acceptance
page 17 • •
Soft to touch
Good ventilation properties
Improved freefall
Easy foldability
Translating technical performance to cost effectiveness
page 18 • •
More nights of protection per net
page 19 • •
Longer lifespan of net + Greater end-user acceptance
Increased number of nights of protection
More protection for every $ spent
