Abstract

The invention belongs to the field of multi-functional textile fabrics, and particularly relates to a textile fabric with double-function of conductivity and magnetic permeability. The conductive magnetic permeable textile fabric comprises the following raw materials: pyrrole, an initiator, Fe3O4 and a textile fabric, wherein the mole ratio of the initiator to the pyrrole is (1-2):1, the mass ratio of Fe3O4 to the pyrrole is (5:1)-(1:5), and the mass of Fe3O4 used in each square meter of the textile fabric is 100-200g. The chemical synthesis technique has the characteristics of high production efficiency, simpleness and convenience in process, good repeatability and in-batch production easiness, and moreover the prepared PPY / Fe3O4 coated textile fabric has the functional characteristics of conductivity, static electricity resistance, electromagnetic shielding, magnetism and the like.

Description

technical field [0001] The invention belongs to the field of multifunctional textile fabrics, and in particular relates to the preparation of textile fabrics with dual functions of conduction and magnetic conduction. Background technique [0002] With the development of science and technology and the continuous improvement of people's living standards, environmentally friendly, healthy and comfortable magnetic functional textile fabrics are favored by people. Magnetic textile fabrics are materials with both textile characteristics and magnetism. , medical and biotechnology, separation and purification and other fields play an important role. Applying magnetic materials to the surface of ordinary textile fabrics through a simple post-finishing method has become a hot spot in the study of functional finishing of textile fabrics.
