Problems solved by technology

The obvious disadvantage of this solution is that the adhesive does not have the required durability for the application with respect to UV radiation
Insect screens made from this weave are highly visible and affect the perception of the observer looking through the screen

Embodiment Construction

[0032] figure 1 The insect screen 1 according to the present invention is schematically shown. The insect screen 1 essentially consists of a woven fabric 2 according to the invention, which is embedded in a frame 3 in a manner not described in detail but known. Weave Web 2 by in figure 1 Warp yarns 4 running vertically in the center and weft yarns 5 running perpendicular to warp yarns 4 are formed. The terms warp thread 4 and weft thread 5 are known to refer to the production flow of weaving. However, within the scope of the invention, for example during the production of the web 2, it is not important which thread is the warp thread 4 or the weft thread 5. The warp yarns 4 and the weft yarns 5 form a knot 6 at each point of intersection. exist figure 1 In this way, the woven netting 2 according to the invention obtains a woven structure with mesh openings 7 . Warp 4 and Weft 5 are bicomponent yarns Including yarn core and cladding 11. In the particularly preferred em...

Abstract

The invention relates to a thread (4, 5) for producing fabrics (2) for insect screens (1), comprising a core which has a coating (11) that comprises a heat-activatable adhesive in order to bond to itself or to other threads of the fabric (2), said core having a higher melting point than the adhesive; to a fabric (2) for insect screens (1) with a mesh (7) web structure, comprising warp threads (4) and weft threads (5) which are connected to one another by means of adhesive at node points (6); to an insect screen (1) comprising a frame (3) and a fabric (2) which is stretched by means of the frame (3); and to a method for producing fabrics (2) for insect screens (1), having the steps of a) providing threads (4, 5) as warp threads (4) and weft threads (5), b) weaving a fabric (2) using the warp threads (4) and weft threads (5), and c) heating the fabric (2) to a temperature which is higher than the melting point of the adhesive and lower than the melting point of the core in order to produce bonds between the warp threads (4) and the weft threads (5) at the thread node points (6). The aim of the invention is to provide such a thread which can be processed into an transparent fabric (2) for insect screens (1) in a particularly efficient manner. This is achieved in that the coating (11) comprises hydrophobic repellents.

Description

technical field [0001] The invention relates to a yarn for the weaving of insect screens, which has a core, wherein the core has a coating comprising a thermally active Binder, used to form a materially cooperating connection with itself or with other yarns of the web, the melting point of the yarn core being higher than that of the binder. [0002] In addition, the present invention also relates to a weaving net for an insect-proof gauze having a mesh weave structure, which includes warp yarns and weft yarns connected to each other by adhesives at nodes. [0003] In addition, the present invention also relates to an insect-proof gauze, which comprises a frame and a weaving net stretched by means of the frame. [0004] Finally, the invention also relates to a method of manufacturing a web for insect screens, comprising the steps of: a) providing yarns as warp and weft; b) weaving the web with the aid of warp and weft; c) weaving the web The web is heated to a temperature ab...
