A kind of tf series paper tube base paper and its preparation process

Abstract

The invention discloses TF series paper tube base paper and a preparation process thereof, and mainly relates to the technical field of papermaking, and the paper is divided into two levels of TF400 and TF500. The paper has the following technical indexes: the quantification is 450 g / m<2>, the transverse quantification allowable error range is + / -3.0%, the longitudinal quantification allowable error is + / -1.5%, the tightness is 0.74 to 0.76 g / cm<3>; the longitudinal ring crush index of TF400 is larger than or equal to 20 N*m / g, the interlayer bonding strength is larger than or equal to 400 J / m<2>, the longitudinal ring crush index of TF500 is larger than or equal to 23 N*m / g, the interlayer bonding strength is larger than or equal to 500 J / m<2>, the water absorption value (60s) is smaller than or equal to 150 g / m<2>, and the finished paper moisture content is 4-6%. The manufacturing process of the paper tube base paper comprises the steps of performing pulping, papermaking and rewinding to obtain the paper tube base paper, and then packaging the finished paper. Pulping is carried out in the pulping process, and starch in pulp is added in the paper forming process. The invention has the advantages of low cost, low water content, low possibility of moisture absorption, high glue absorption speed, high pipe forming pressure, short drying time and the like.

Description

technical field [0001] The invention mainly relates to the technical field of papermaking, in particular to a TF series paper tube base paper and a preparation process thereof. Background technique [0002] With the rapid development of my country's economy, paper core and paper tube products have been widely used in papermaking, packaging, textile and chemical fiber industries due to their advantages of low cost, light weight, easy recycling, and pollution-free. It can be used not only as the inner core of various webs and cardboards, but also as textile bobbins for synthetic filaments, polyester, polypropylene fibers, spandex, etc., especially the paper bobbins used in the textile industry have gradually replaced tapered bobbins . While people pay attention to the quality of paper cores and paper tubes, great changes have taken place in the concept of technical requirements for the base paper used. [0003] At present, the domestic paper tube base paper mainly has the fo...

Problems solved by technology

[0004] (1) The base paper of high-grade paper tubes absorbs glue slowly and dries slowly when the tube is rolled. During the peak season, it must be dried in a drying room. The drying time is long and the cost is high;

[0005] (2) In the wet season, the finished paper absorbs moisture quickly, and high moisture affects glue absorption and drying;

[0006] (3) The water in the tube is high, the surface layer dries quickly and shrinks, and the outer layer of the paper tube is subjected to uneven force, which leads to the bending of the paper tube and affects the use
