Representative documents include: Patent No. ZL201310441643.5, the invention uses the method of passing the yarn through an air vortex tube, uses hot air to generate a rotating airflow in the same direction as the yarn, twists the yarn, and frees the free fiber Rubbing back on the yarn body reduces hairiness, but theoretically, the twisting of the yarn by airflow alone has limited force, and the free fibers can only be attached temporarily, and the yarn body is still easy to be exposed later; the patent number is ZL200710052991.8 , the invention adopts an untwisting and heating yarn hairiness reduction device installed on the yarn advancing channel, first untwisting the yarn, and re-twisting after heating. In principle, the fiber can be effectively re-twisted into the yarn body, but this device Located in front of the grooved drum, the yarn will still produce a lot of hairiness after being rubbed by the grooved drum
In addition, there is also online chemical finishing of the yarn during the winding process to reduce hairiness. The representative literature is: Patent No. ZL200510023420.2, which chemically finishes the yarn during the winding process. Completely soaked in the finishing agent, followed by rapid drying. This method not only makes the surface of the yarn smooth, but because the finishing agent completely penetrates into the yarn body, it may change the overall performance of the yarn. However, rapid soaking can be achieved on a high-speed winding machine. It is difficult to dry and dry, and it also requires additional energy consumption
In addition, there is also waxing on the yarn during the winding process to reduce hairiness and increase wear resistance. The representative literature is: Patent No. ZL201310665193.8, which is to polish a small amount of wax on the yarn through friction during the winding process. The surface of the yarn can enhance the wear resistance of the yarn in the subsequent process, but the limitation of rubbing the yarn with a solid wax block is that only one side of the yarn surface is covered with wax, which cannot improve the wear resistance of the yarn in an all-round way

Abstract

The invention relates to online processing of hairiness on the surface of a yarn, wherein hairiness of the yarn is reduced, the antifriction performance of the yarn is enhanced, and the quality of the spooled yarn is improved. The invention particularly relates to an online micro-processing method for yarn spooling and belongs to the field of textile processing. A yarn surface structure micro-processing device is mounted between an air splicer of a spooled yarn operating channel and a groove drum; during yarn spooling, the yarn through the yarn surface structure micro-processing device holding micro-processing slurry winds in the groove drum to from a cone yarn; and when the yarn passes through the yarn surface structure micro-processing device, under the action of the micro-processing device of the yarn, hairiness on the surface of the yarn is attached to the surface of the yarn under the action of a frictional force, and meanwhile, the slurry adheres and fixes the attached hairiness and forms a slurry membrane layer. The online micro-processing method for yarn spooling provided by the invention can remarkably reduce hairiness of the cone yarn, fundamentally inhibits hairiness of yarn generated by wear of the yarn in the next step, and meanwhile, retains the original softness and elasticity in the yarn, and use of the yarn is not affected.

Description

technical field [0001] The invention relates to on-line processing of yarn surface hairiness to reduce yarn hairiness, strengthen yarn anti-friction performance, and improve winding yarn quality, in particular to an online micro-processing method for yarn winding, which belongs to the field of textile processing. Background technique [0002] Hairiness is one of the important indicators to measure yarn quality. A large amount of yarn hairiness will adversely affect the production efficiency of the subsequent weaving process and the appearance of the final fabric. Therefore, reducing yarn hairiness is of great significance. In the winding process, the yarn needs to be in contact with the yarn guide parts many times, and the high-speed and severe friction makes the fibers on the surface of the yarn easily pulled out to the surface of the yarn body, forming hairiness. The data show that the winding process can increase the yarn hairiness by 100 %-700%, especially at the end of ...
