Gas Singeing

Gas Singeing

In this method, gas burners are used to singe one or both sides of the fabric during a single passage of the cloth over the flames.The machine consists of two or more burners supplied with a suitable mixture of gas and air under pressure.The width of the sets of burners can be adjusted to suit the width of the fabric: the length of the flame and hence the intensity of heat can also be adjusted.The cloth in open width is drawn over the flame at high speed at 90 meters per minute, so as to burn the protruding fibers without damaging the cloth.The burn: used is normally a simple iron pipe with suitable perforations along its is length.In the case of slot burner, the width of the slot is adjustable.The mixture of gas and air may be prepared separately and compressed or it may be formed by allowing compressed gas ado and air to mix immediately before the entrance of the slot the chamber.While singeing.the cloth is allowed to run through the pro then

Gas sinseing machine

While singeing.the cloth is allowed to run through the machine and then burners are ignited.While stopping the machine, .the flames are first extinguished and then the machine stopped.The high temperature (300 to 500° C) met with in the singeing does not damages the cloth because the time of contact is only fraction of a second.The singeing room is separated from other departments in the mill.The singed cloth is quenched by passing. It  through a mangle revolving in a water box to extinguish sparks and to reduce the risk of fire to the minimum

Synthetic fiber fabrics can also be singed, During singeing such fabrics, the protruding fibers melt and recede from the flame forming minute beads.These absorb the dye faster than.the rest of the fabric giving specky dyeing.In order to avoid this.defect, singeing is carried out after dyeing.In the case of terycot  fabrics, singeing controls pilling
