Embodiment 1

[0020] Example 1: Gradient wrapping treatment of cotton yarn hairiness in the warping process

[0021] The device of the present invention is externally connected to a drive motor through a drive belt 1, which drives the funnel-type friction device to rotate at a high speed counterclockwise at a speed of 8000 rpm, and the heat setting device is heated by an external power supply, so that the temperature of the ironing yarn trough rises to 135°C , the taper between the upper cone wall 12 and the lower cone wall 14 of the hollow cone 11 and the cross section of the hollow shaft 15 is 3:1, the upper cone wall 12 has a wall width of 20 mm, and the convex cone wall 13 has a width of 15 mm. mm, the width of the lower cone wall 14 is 10 mm, the grid through holes on all cone walls and the grid through holes on the upper end wall of the hollow shaft 15 have a diameter of 2 mm, and the outlet end 3 of the directional suction pipe is externally connected to a negative pressure exhaust fa...

Abstract

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.

Description

technical field [0001] The invention relates to a device for gradient wrapping yarn hairiness, which belongs to the technical field of textile processing. [0002] technical background [0003] Hairiness is one of the important indicators to measure the quality of yarn. Yarn hairiness not only affects the production efficiency of weaving, knitting and other post-processes, but also affects the appearance quality of the final product. Especially today, when high-speed shuttleless looms are widely used, reducing yarn hairiness is of great significance. [0004] Yarn hairiness occurs in the spinning process. The mechanism is that after the end of the fiber transferred from inside and outside is exposed to the yarn body, it breaks away from the grip of the jaws and cannot re-enter or wrap around the main body of the yarn body, forming hairiness. The hairiness increases in the winding and warping process. The root cause is that there are many hairiness on the surface of the yarn ...
