The singeing aims at burning off the fluff on the cloth surface, so that the fabric is beautiful and smooth, and the phenomenon of uneven dyeing caused by the existence of the fluff during dyeing and printing is prevented. When the fabric is singed, the fluff on the fabric is rapidly heated and burnt, and when the fluff is not heated to a fire point, the fluff is separated from the flame, so that the purpose of burning the fluff without influencing the fabric is achieved. The applicant obtains through numerous experiments that the fabric passes through flame at a temperature of 450 ℃ at a speed of 100-120 m/min in an open width state, so that fluff of the first outer covering wire 13 and the second outer covering wire 22 of the fabric in the example can be perfectly treated, and the whole fabric is not affected.
