The invention relates to a device for gradient wrap line hairiness in the textile processing technical field. The device is made of erecting bed, pedestal, bracing frame, funneling rubbing device, heat setting device, orientation aspiration channel, first driving pulley, second driving pulley, yarn gatherer, yarn let-off gear (stand). The air inlet of orientation aspiration channel is corresponding with the outer side of the hollow cone outside wall surface, and implement lateral negative pressure-pumping on inner side of the hollow cone not only help to wrap the yarn hairiness orderly in fixed direction, preventing increase of fiber-gathering or yarn fault. Increasing hairiness holding strength of hollow cone side and diameter of the upper cone wall obviously exceeds that of the lower cone wall and diameter of the hollow cone, help to realize gradient wrapping of yarn hairiness, high-speed and high-efficiency looping, heat setting device carries out slot extruding and high-temperature shaping to yarn after plumage looping, increasing stability and consistency of looping structure.
