preparation example Construction

[0027] The preparation method of the electromagnetic shielding sandwich braided rope provided by the present invention includes an electromagnetic core layer and an outer braided layer; the electromagnetic core layer includes a fiber-based linear material and a conductive material and a magnetic material loaded on the surface of the fiber-based linear material; The electromagnetic shielding sandwich braided rope is obtained by braiding the electromagnetic core layer and the outer braided layer through an 8-32-spindle rope braiding process. The shielding layer with different functions is braided and wrapped into a rope by core-spun braiding, and a composite shielding braided rope with high strength and wear resistance can be prepared. The composite shielding braided rope has good flexibility and shielding performance, and can be used in flexible and durable Preparation of wearing shielding fabric.

[0028] The fiber substrate is preferably cotton fiber non-woven fabric; the con...

Embodiment 1

[0037] This example provides an electromagnetic shielding sandwich braided rope based on braiding technology. The sandwich layer is a composite of a cotton fiber non-woven fabric core layer with a conductive and magnetically conductive coating. Pyrrole conductive polymer, and spray nano-Fe on the surface 3 o 4 Composite to obtain a composite shielding conductive fiber core layer. The outer weaving yarn is silver-plated nylon yarn, and the braided sandwich shielding rope is obtained by weaving the cotton fiber-based shielding fiber core layer with a 16-spindle rope knitting machine. Specifically include the following steps:

[0038] S1. By placing the cotton fiber non-woven fabric strip in the pyrrole monomer solution, polypyrrole is polymerized in situ on the surface of the cotton fiber by dropping an oxidizing agent, so that an effective conductive path can be formed on the surface of the cotton fiber, such as figure 1 Shown in (a). Using a low-aperture high-pressure spra...

Abstract

The invention provides an electromagnetic shielding sandwich braided rope, a preparation method and application thereof. The electromagnetic shielding sandwich braided rope is characterized in that an electromagnetic core layer and an outer weaving layer are woven into a sandwich composite shielding rope through a weaving process, wherein the electromagnetic core layer realizes electromagnetism through in-situ polymerization of polypyrrole and spraying of nano Fe3O4 magnetic particles, and the outer weaving layer is made of silver-plated nylon stranded yarns, has good conductivity and wear resistance, and wraps the surface of the electromagnetic core layer in a staggered manner to form a sandwich structure, so that through the operation, the shielding layers with different composition contents are woven and wrapped into a rope in a coating polymerization and core-wrapping weaving mode, and the high-strength and wear-resistant composite shielding braided rope is prepared and can be used in special fields. The preparation method is simple and efficient, and the problem that a traditional shielding material is low in durability is solved.

Description

technical field [0001] The invention relates to the technical field of functional textiles, in particular to an electromagnetic shielding sandwich braided rope and its preparation method and application. Background technique [0002] With the rapid development of electronic technology, more and more electronic products and equipment are used in people's production and life, and most electronic products such as microwave ovens, refrigerators, electric blankets, computers, radios, radars, etc. have different transmitters produce electromagnetic radiation to a certain extent. Electromagnetic radiation not only causes mutual interference between electronic products, but also pollutes the living space of human beings and endangers human health. It is a kind of "invisible, unsmellable, and intangible" pollution, known as "invisible killer". To this end, various countries or international organizations have successively formulated various strict regulations to prevent electromagne...
