Problems solved by technology

In the existing preparation method of paper threading rope, a single strand in each bundle of strands is twisted again to form a rope yarn, and then braided into a rope. The area of ​​the braided rope prepared by this preparation method in contact with the paper during use is Relatively small, resulting in relatively small friction between the paper rope and the contact object, so that relative sliding between the paper rope and the contact object is easy to occur, and at the same time, the paper rope is prone to elastic deformation during use, resulting in The paper thread becomes longer and the holding ability is unstable

Embodiment 1

[0056] Example 1 Preparation of threading rope 1#

[0057] The preparation method of paper thread rope 1# comprises the following steps:

[0058] S1) Strand making: Select nylon 6 filament with a fineness of 1260Den and a breaking strength of 8.5g / D as the rope making material, and twist three nylon 6 filaments into S-direction rope yarn and Z-direction rope through a twisting machine Yarn, the twist of each rope yarn is 200T / m, and the number of S-direction rope yarns and Z-direction rope yarns are the same.

[0059] S2) Parallel pre-weaving: First, pass the 4 Z-direction rope yarns through the pre-loom and arrange them in a row and wind them on the 4-count yarn bobbins. In the same way, combine the 3 Z-direction rope yarns into a The rope bundles are wound on 4 bobbins, then 4 S-direction rope yarns are wound on 4 bobbins for rope bundles, and finally 3 S-direction rope yarns are wound on 4 bobbins for rope bundles superior.

Abstract

The application discloses a paper thread and a preparation method thereof, belonging to the technical field of rope preparation. The preparation method of the paper threading rope includes: S1, making strands; S2, doubling and pre-weaving: ensuring that the tension between each rope yarn in the S-direction rope bundle and the Z-direction rope bundle is consistent, the arrangement is uniform, and the rope yarns The average value of the difference in length is 1-5cm / 100m; S3, rope making: weave the rope bundle obtained by step S2 parallel thread pre-weaving to obtain a paper threading rope, and maintain each rope yarn in each rope bundle in parallel in the braiding process And enter the weaving point in a row, thus weaving to obtain the paper thread. The method prepares the obtained paper rope, so that each rope yarn in each weaving unit of the paper rope is closely distributed in a row, which increases the contact area between the paper rope and the contact objects such as paper rolls, and improves the efficiency of the paper rope. The gripping ability of paper rope to contact objects such as paper rolls.

Description

technical field [0001] The application relates to a threading rope and a preparation method thereof, belonging to the technical field of rope preparation. Background technique [0002] The threading rope for papermaking machinery is a rope that guides the paper roll, cardboard or tissue paper that is being produced through the dryer, the threading roll, the sizing machine and other parts when the paper machine is turned on or off. The diameter of conventional threading ropes is generally between 6mm-16mm. [0003] In the process of using the threading rope, there needs to be sufficient pressing force and adhesion between the threading rope and the paper, so the threading rope needs to have a large friction performance, and at the same time, the threading rope needs to have a small static elongation to ensure that the threading rope has an effective and stable grip. In the preparation method of the existing paper threading rope, a single rope strand in each bundle of rope s...
