Problems solved by technology

[0007] Aiming at the technical defects of poor dispersion performance of polyester fiber in papermaking liquid in the papermaking process in the prior art, insufficient bonding strength between fiber and matrix material, and low papermaking efficiency, the present invention proposes a high-efficiency polyester fiber The papermaking method is characterized in that the polyester fiber surface is grafted and modified by the plasma method. After the grafted allylamine is modified, the surface hydrophilicity of the polyester fiber is significantly improved, and the mechanical properties of the polyester fiber are not damaged. In terms of performance, the bonding strength between the fiber and the matrix material is improved. Further, the paper-made polyester fiber paper is laminated on the surface of the PTFE ultra-thin film by using glow discharge plasma, which improves the papermaking efficiency and paper body performance.

Abstract

The invention provides a method for highly efficiently making paper by using polyester fibers. The surface of the polyester fibers is grafted and modified with allylamine through a plasma technology to obviously improve the hydrophilicity of the surface of the polyester fibers and improve the bonding strength of the fibers and a matrix material without damaging the mechanical performances of the fibers, and made polyester fiber paper is laminated to an ultrathin polytetrafluoroethylene film through glow discharge plasma to improve the papermaking efficiency and the performances of the paper. The method has the advantages of fast processing speed, high efficiency, great improvement of the making efficiency of the polyester fiber paper, and suitableness for industrial production.

Description

technical field [0001] The invention relates to the field of functional paper processing, in particular to a high-efficiency papermaking method using polyester fibers. Background technique [0002] The paper industry is one of the ten pillar industries of the national economy in developed countries. The emergence of the laser industry has promoted the development of the optoelectronic industry, which is the pillar industry of the information industry. After years of rapid growth, my country's paper industry has gradually entered a mature stage after 2012. In recent years, my country's paper industry has transformed and upgraded, and gradually developed towards functional paper. The functional paper prepared by the fiber developed in the new textile field through the papermaking process has become the key to the upgrading of the papermaking industry. [0003] With the development of the textile industry and the deepening of research on chemical fibers, more and more new var...
