Background
The fluff on the surface of the grey cloth fabric can influence the quality of dyeing and finishing processing and the performance of clothes, and the fabric is smooth and clean by singeing treatment; meanwhile, the fluff on the gray cloth is removed, so that the ready-made clothes are not easy to pilling. Singeing is therefore the first means to reduce fuzzing and pilling.
The prior singeing process is that the gray cloth rapidly passes through the flame of a singeing machine in a flat and amplitude manner or is wiped across a glowing metal surface, so that the fluff on the cloth surface is burnt due to rapid temperature rise, and the gray cloth is compact, thick and slow in temperature rise and leaves the flame or glowing metal surface when the temperature does not reach an ignition point, so that the fluff is burnt off and the fabric is not damaged.
However, in the singeing process, the speed of the greige cloth passing through the flame or the glowing metal needs to be accurately controlled, the speed of the greige cloth is completely dependent on the size of the flame used or the temperature of the metal, and both of the speeds are greatly dependent on the operation experience of an operator; in addition, the control has slight deviation, and the hidden danger that the whole cloth is burnt or even a factory building generates fire exists.
