| Monofilament fabrics |
| W : |
|
Mesh opening in microns (1 µm = 0,001
mm) vacuum dimensions. |
| Item : |
|
Identification of a DIATEX fabric. |
| Mesh count : |
|
Number of yarns per inch (= 2,54 cm) and
per cm in the 2 senses (warp / weft). |
| Open area
: |
|
Proportion of the vacuum surface compared
with basic surface (outside dimensions of the mesh). |
| Yarn diameter : |
|
Monofilament diameter in microns. |
| Tensile
strenght : |
|
Mechanical resistance to the breaking point
in daN/5 cm (= Kg/5 cm). The test sample measures 5 cm of width
and is stretched in the direction length until rupture. |
| Weight : |
|
Surface weight expressed in grams / m². |
