Problems solved by technology

[0006] When different insecticides are incorporated into a polymer matrix (such as disclosed by Vestergaard Frandsen et al. WO03 / 063587) or if different insecticides are incorporated with a synergist into a polymer matrix for a pet collar (such as As disclosed in WO06 / 1247067 to Albright), the movement of insecticides can be difficult to control because a movement enhancer or inhibitor of one insecticide or synergist may affect the movement of other insecticides

Embodiment Construction

[0025] In certain embodiments of the invention, a first portion (eg, a first type of filament) can have incorporated therein a first type of insecticide (eg, a pyrethrin) having a first speed of movement and a first insecticidal efficiency. A second portion (eg, a second type of filament) may incorporate therein a synergist, such as PBO, having a second speed of movement. In order to achieve the optimal amount of released insecticides and synergists, the first and second movement speeds can be achieved independently by movement inhibitors or movement accelerators, because movement inhibitors and accelerators are present in the line in separate parts, such as in separate filaments, without interfering with each other.

[0026] Optionally, the first portion may incorporate therein a first type of insecticide having a first speed of movement and a first insecticidal efficiency. The second part may incorporate therein a second type of insecticide, for example to combat insects re...

Abstract

An insecticidal thread comprising a first type of filaments and a second type of filaments according to the invention. The first type of filaments has an insecticide or a synergist or both incorporated in a polymeric material of the first type of filaments. The second type has an insecticide or synergist or both incorporated in a polymeric material of the second type of filaments. The content of insecticide or synergist in the second type of filaments is different from the content of insecticide or synergist of the first type of filaments. Alternatively, the thread is an extruded monofilament with a first and a second part with insecticide and / or synergist.

Description

technical field [0001] The present invention relates to an insecticidal thread, such as thread used in mosquito nets and fabrics. Background technique [0002] Different pesticidal treatments of nets and different applications of such nets are disclosed in the prior art, for example the general treatment of nets in International Patent Application WO 01 / 37662 by Skovmand, International Patent Application by Bauer and Skovmand Use as fence in WO 03 / 003827, use as protective cover in International Patent Application by Vestergaard Frandsen. [0003] One of the problems encountered with mosquito nets and insecticidal fabrics has been shown in fieldwork where the efficiency of the nets decreases when exposed to sunlight or due to general heat exposure. In order to maintain long-lasting effectiveness, it has been proposed in Vestergaard Frandsen's International Patent Application WO 03 / 063587 to incorporate the biocide inside the fiber structure so that the biocide gradually mig...
