Abstract

The invention relates to a processing method and a processing device for processing colored point knot yarns. Drawn silver is fed through the feeding end of a cover casing of a high-voltage electric field; an output end is pulled by a front roller; fibers are twisted by a twister and then are wound on a yarn tube; a knot release opening is formed in the side surface of the cover casing of the high-voltage electric field; input knots are subjected to intersected mixing with the fibers under the effect of the electric field force; cotton strips fed by the cover casing of the high-voltage electric field are pulled by a group of roller leather rings; the humidified cotton strips are blown by a spray nozzle at an inlet, then enter into a cavity and then perform oriented accelerated motion under the effect of an electrostatic field; in the process, the fibers are further straightened by the electric field force and the friction force, so that hooking is reduced. The motion tracks of the colored knots and the fibers are intersected, then the colored knots are randomly distributed and mixed in the fibers; the cotton strips are twisted at an outlet by the twister so as to form the colored point knot yarns. The variety replacement process is simple; the colored knot use efficiency is improved; a roving process in the whole processing process is reduced; the process flow is shorter and cleaner.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a processing method and a device for producing colored dot knotted yarn. Background technique [0002] At present, the main method of producing knot yarn is to add dyed knot in the process of free cotton mixing, and after mixing with raw cotton, go through the carding, drawing, roving and spun processes of ordinary yarn spinning system successively. Due to the difference in structure from ordinary yarns, there are differences in strength, elongation at break, etc. The production of colored dot knot yarns requires special adjustments and parameter settings in each process. In the cotton mixing process, dyed knots are mixed with raw cotton. Once the color and type of knots need to be changed, the mixing box needs to be thoroughly cleaned to remove the original types of neps remaining on the channel and inner wall; the carding process is The most critical step in the w...
