Product form
Fabrics, single and multilayer, can be heat-slit into tube configurations. Tubes are made by slitting two layers of fabric together with a heated knife, creating two flat seams at either side of the tube. Heat-slit fabric edges are melted or fused together to increase durability and decrease fraying. The heat-slit seam has a limited strength and should be used as a transport seam only, e.g. for injection molding.
All fabrics with thread diameters < 250 µm and mesh openings < 500 µm can be heat slit . Heat-slit tubes are defined by the inner diameter which is tested with a mandrel: tube diameters range from 8 - 320 mm. The inner diameter of the heat-slit tube does not equal the flat width of the the tube itself. The effect of welded "wings" on either side has to be taken into consideration; the width depends on the mesh type. |

Make-up
Tubes are wound onto standard cores:
polyester discs have an inner square hole
30 x 30 mm and an outer diameter of 61 mm. Upon request tubes can also be rolled onto special cores: An ABS ring having an inner diameter of 76 mm (3"). Depending on fabric type and tube dimensions, roll length of up to 500 m are possible. |

Packaging/labeling
Tube rolls are packed into PE bags which are closed by welding. The label contains the following information:
manufacturer, material, dimensions (diameter
in mm, length in m), manufacturing date, order number, roll number.
Heat-slit tubes made of SEFAR MEDIFAB fabrics are double bagged. |
