Singeing Positions:

There are three singeing positions. These are:

1. Singeing on to free guide fabric:

This is the most intensive singeing position with highest efficiency. In this position, the flame bounces onto the free-guided fabric at right angles. This position is usually recommended for singeing of fabrics with all natural fibres (e.g. cotton), regenerated fibres and blended fabrics, which have been tightly woven and have weights over 125 g/m2

2. Singeing onto water-cooled roller:

In this position, the flame bounces at right angles onto the fabric while the fabric passes onto water-cooled guide roller. This position avoids the penetration of the flame into the fabric. The flame does not pass through the fabric, and because of the fabric passing onto water-cooled roller, any thermal damage of temperature-sensitive synthetic fabrics is avoided.  This position is usually recommended for all blended and synthetic fabrics as well as for fabrics having weights less than 125 g/m2 and fabrics with open structure.

3. Tangential Singeing :

In this position, the singeing flame falls on the fabric tangentially. The flame touches only the protruding fibres without having any significant contact with the main fabric body. This position is usually recommended for very light weight and sensitive fabrics as well as fabrics with broken filaments.

Distance between Flame Burner and Fabric:

As the energy content of the flame is lower the farther it is from the burner, the singeing efficiency is consequently decreased by increasing the burner-fabric distance. The distance between the burner and the fabric is usually in the range of 6-8mm but it can be adjusted in a range from 6-20mm.

Flame Width:

All good singeing machines come with a provision of flame width adjustment according to the width of the fabric. This is essential to optimise the gas economy.
