Problems solved by technology

Based on the above changes, the original tube cover paper has the following problems: 1. The colored tube cover paper is dark in color and fades seriously, causing the chemical fiber filaments near the bottom of the tube to be polluted by the color migration of the cover paper
As the bobbin storage time prolongs, the chemical fiber oil solution on the tow will be partially absorbed by the surface of the bobbin cover paper; part of it will permeate into the inner layer of the bobbin along the paper and the few fiber gaps, resulting in the bottom of the bobbin The fiber bundles of chemical fiber filaments are scattered due to the loss of the protection of the oil agent, which makes the bundling property of the superfine chemical fiber filaments not good, and it is easy to hang the filaments, and cannot be completely unwound, which seriously affects the automatic mass production of high-speed spinning machines
3. The cover paper of the bobbin tube has low covering power and serious see-through

Abstract

The invention discloses a manufacturing method of special bobbin cover paper for ultrafine chemical fiber filaments. The manufacturing method comprises: sufficiently mixing softwood pulp and hardwood pulp, a coloring material, a penetration assisting material, a covering material and a color fixing material to prepare pulp; carrying out papermaking to obtain raw paper of the bobbin cover paper; carrying out low-temperature acidification treatment on the raw paper by sulfuric acid to obtain the bobbin cover paper; after washing the acidified bobbin cover paper with water, neutralizing and plasticizing, carrying out surface modification treatment including oil prevention, abrasion resistance and the like; finally, drying, winding, cutting and packaging to obtain the bobbin cover paper. The bobbin cover paper prepared by the method has the characteristics of no fading, no oil absorption and no oil penetration, good surface wear-resisting performance, bright color and high covering capability, completely meets the requirements of users and has a good utilization effect.

Description

technical field [0001] The invention relates to a production method of bobbin cover paper wound with superfine chemical filaments, which is suitable for the chemical fiber industry, and belongs to the technical field of papermaking. Background technique [0002] In recent years, the chemical fiber industry has developed very rapidly. There are more and more types of chemical fiber filaments, and the chemical fiber filaments are becoming finer and finer. Changing from the original manual splicing to mechanized automatic splicing requires a very high tailing rate in spinning, that is to say, all the yarn at the bottom of the bobbin is required to be returned. Based on the above changes, the original tube cover paper has the following problems: 1. The colored tube cover paper is dark in color and fades seriously, causing the chemical fiber filaments near the bottom of the tube to be polluted by the color migration of the cover paper. 2. The cover paper of the bobbin is oil-abs...
