Rolling method in chemical fiber high-stretch yarn adding process

Abstract

The invention discloses a rolling method in chemical fiber stretch yarn adding process, which can reduce the labor intensity and shorten making-up time. The rolling method comprises the following steps: (1) an operator uses a first negative pressure yarn absorption device to absorb high-stretch yarn and draws the high stretch yarn to be close to a second negative pressure yarn absorption device to transit the high-stretch yarn to the second negative pressure yarn absorption device, and then sends the high-stretch yarn into steel wire hooks on travelers; (2) a spindle drives a spool to rotate and the second negative pressure yarn absorption device is used for pushing the high-stretch yarn absorbed by the second negative pressure yarn absorption device forward so that the high-stretch yarn falls in a yarn hanging groove of the lower flange of the spool; when rotating with the spool, the high-stretch yarn is driven by the travelers to move up and down so that the high-stretch yarn coils on the spool in a tower shape; and (3) when the spool is full, the spindle is stopped and the full spool is removed quickly and replaced with an empty spool, and then the steps (1) and (2) are repeated. The invention can greatly improve the spinning speed, thereby greatly improving the production effect.

Description

technical field [0001] The invention relates to a chemical fiber texturizing process, in particular to a winding method in the chemical fiber texturizing process. Background technique [0002] The so-called chemical fiber texturing process is the process of texturizing the raw silk and winding it on the bobbin by using a high elastic machine. see figure 1 As shown, the steps include: 1) finding the end, pulling out the yarn end from the raw yarn cake 1 on the raw yarn frame 14, then passing through several yarn guides, and then feeding it into the upper roller 2; 2) heating, passing through the upper roller The sliver held by the roller 2 is then sent to the upper heating box 3 for heating. The purpose of heating is to make the sliver in a plasticized state by heating, so as to prepare for false twisting and drawing processing by the subsequent false twister 5; 3) cooling , the thread coming out from the hot box 3 will be cooled to the optimum processing temperature by the...

AI Technical Summary

Problems solved by technology

At present, the operator pulls the high-elastic yarn completely by hand, which makes the labor intensity of the operator very high and takes a long time in the process of changing the bobbin each time, so it is necessary to reduce the speed of the spindle to match it. Processing less efficient
