[ Olyset Technology ]
Traditional mosquito nets require regular dipping in insecticide to maintain effectiveness in repelling mosquitoes, as insecticide is dislodged during regular use and washing. There are also practical problems in re-treating nets in remote areas, a long way from the urban centres where stocks of insecticide and trained advisors are located.
Sumitomo Chemical engineers set about developing the first net that does not need this constant re-treatment. The process begins with insecticide-impregnated beads, which are extruded into fibre and warped onto bobbins to be knitted into rolls of netting.
The netting rolls are cut into sized panels which are machine-stitched into the nets themselves. Chemical and physical checks are made before the nets are sent for delivery by land, sea and air.
Because the insecticide is incorporated within the fibres, Olyset Nets are truly ready-to-use, long-lasting and never in need of treatment. Washing does not diminish their effectiveness, and they have been shown to still repel mosquitoes seven years after initially being put into use.
