Abstract
The invention refers to a greenhouse screen comprising strips of film material that are interconnected by a yarn framework of transverse threads and longitudinal threads to form a continuous product, wherein the yarn framework is thermally bonded to at least one side of the strips of film material, wherein also those parts of the yarn framework that is thermally bonded to the strips have liquid-transporting capacity by capillary action. The amount of yarn in the yarn framework interconnecting and holding the strips can herewith be reduced.
Claims31
A greenhouse screen comprising strips of film material, said strips extending in a longitudinal direction of the screen and are interconnected by a yarn framework of transverse threads and longitudinal threads to form a continuous product, said yarn framework having liquid-transporting capacity by capillary action, wherein:
- the yarn framework is thermally bonded to at least one side of the strips of film material, so that at least a part of the material in the film strips and/or the yarn framework has been melted or softened and bonds to parts of the yarn framework and/or film strips at contact points, wherein also those parts of the yarn framework that are thermally bonded to the strips have liquid-transporting capacity by capillary action.
