Singeing refers to the process of quickly passing the fabric through a flame or rubbing it over a hot metal surface to burn off the surface fluff. Textile processing of fibers will produce a lot of hair on the surface of yarns and fabrics, which will affect the process effect of dyeing and finishing.
According to the requirements of the product, some yarns (such as spun silk) and most fabrics have to go through the singeing process to make the surface smooth and smooth, and the texture clear. The flame temperature of singeing is usually 900~1000℃, and the surface temperature of the hot metal plate is also 800℃, which is higher than the decomposition temperature or ignition point of various fibers.
When singeing, the fabric passes through the flame at a high speed under a certain tension. Because the fluff protruding from the surface is relatively large, it instantly heats up to the ignition point and burns, while the yarn fabric body is twisted and interwoven tightly, so the heating speed is not so Quickly, so it is rarely affected.
