Reduced during sunlight or because of in general heat exposure.To keep lasting efficiency, in the Vestergaard Frandsen world
Had been proposed that in patent application case WO 03/063587 and merge insecticide inside fibre structure so that insecticide gradually moves to fiber
Surface.The Olyset of institute of company registration markMosquito net includes the single fiber being incorporated in insecticide in yarn
Polyethylene yarns.
To strengthen efficiency on the basis of general, it has been suggested that association is multiplied into agent and is included in fabric and mesh.For example,
In Hataipitisuk U.S. patent application case US2007/0009563 and the international application in Mooney et al.
In WO90/14006, it is proposed that PBO is as the efficiency enhancers in insecticidal fibres and fabric.Koradin et al. international monopoly Shen
Please case WO06/128867 and Karl et al. WO06/128870 suggest that PBO multiplies agent as the association in fabric and mesh.
Generally, there is the problem of metabolism of gradually serious insect confrontation insecticide, and have been proposed that piperonyl fourth oxide
(PBO) it is used for resisting resistance.With field sprinkling relatively, it is known that PBO systems are as resistance depressant, such as convey Rothamsted
The those disclosed herein of UK patent application cases 2 388 778.Samson et al. United States Patent (USP) 5 503 918 discloses amyl group pectin conduct
Desinsection association in camp fabric multiplies agent, and Yeadon et al. United States Patent (USP) 3 859 121 discloses and uses PBO as in packing material
Association multiply agent.
When different insecticides are merged in polymer substrate (such as Vestergaard Frandsen et al. WO03/
063587 those disclosed herein) if or different insecticides and association multiply agent and be together merged in polymer substrate (example for Pet neck ring
Such as Albright WO06/1247067 those disclosed herein), the movement of insecticide is likely difficult to control, because an insecticide or association multiply
The mobile accelerator of agent or inhibitor may influence the movement of other insecticides.Therefore, if it is desired to which certain of different insecticides is released
Go out, this is difficult to reach, and wants although this is height.
Especially with regard to mosquito net or the fibroid desinsection blind of other patterns, different insecticides or multiply agent with association and combined
Insecticide through control disengage what is be intended to.
The content of the invention
Therefore the purpose of the present invention is to provide for a kind of method for being used to produce fiber product processed, wherein insecticide kills with another
