    摘要: The darkening screen comprises two fabrics, namely a first fabric (10) which comprises in machining direction first strips of film material and first threads (2) in between the first strips, and a second fabric (11) which comprises in machining direction second strips of film material and second threads (6) in between the second strips. The first (2) and the second threads (6) of the first (10) and the second fabric (11) have water transporting capacity. In order to obtain improved moisture transporting properties whilst maintaining a low hemispherical light transmission the first threads (2) are aligned with said second threads (6) and are situated, in a direction perpendicular to said first (10) and second fabric (11), opposite to said second threads (6) to form pairs of first and second threads. In a number of these pairs the first thread (2) is connected at different locations by cross-connections (16) to the second thread (6), more particularly by means of a first yarn (4) of the first fabric which extends in the cross-machining direction, to thereby fix the first fabric (10) to the second fabric (11). The cross-connections (16) preferably hold the first threads (2) at least at the location of the cross-connections (16) against the second threads (6).
