Yarn singeing process (known as gassing) is one of the latest methods to remove the hairiness from the yarn surface so that a smoother surface of yarn could be available for the fabrication causing less fabric hairiness and ultimately affecting positively the fabric properties especially the pilling. The singeing of yarn is accomplished by passing it over a gas flame at a speed sufficient to burn away the protruding material without scorching or burning the yarn. Different yarn singing machine variables like winding speed, gas pressure and air pressure may affect different properties of the...
