Embodiment 1

[0062] Using the carbon filament core-spun yarn of the present invention as the braided yarn, according to the fuzzy and shielding requirements of the private parts of the human body, the carbon filament core-spun yarn diamond-shaped grid-shaped electromagnetic shielding braid is designed, such as Figure 1a shown. The interweaving area of ​​the carbon filament core-spun yarn forms a diamond-shaped grid, forming three areas in the shape of a diamond-shaped grid, that is, the two-axis carbon filament core-spun yarn weaving area (2-axis electromagnetic wave shielding functional area, BS area); Filament core-spun yarn weaving area (area with electromagnetic wave shielding function, SI area and SII area); and other yarn interweaving area (area without electromagnetic wave shielding function, NS area). The specific process parameters and the measured values ​​of the electromagnetic shielding effectiveness EMSE5 parameters are shown in Table 1. After the fabric is woven, it can be d...

Embodiment 2

[0064] The carbon filament core-spun yarn of the present invention is used as the weaving yarn and interlining warp yarn, and according to the fuzziness and shielding requirements of the private parts of the human body, the single-axis partial knitting yarn and part of the interlining warp are designed to be carbon filament core-spun yarn diamond-shaped strips Electromagnetic shielding braids such as Figure 1b shown. Axis I carbon filament core-spun yarn weaving yarn and interlining warp yarn form a diamond-shaped grid, forming three diamond-shaped grid-like areas, that is, two-axis carbon filament core-spun yarn knitting area (2-axis electromagnetic wave shielding functional area, BS area) ; Uniaxial carbon filament core-spun yarn knitting area (with electromagnetic wave shielding function area, SI area and SIV area); and other yarn interweaving area (no electromagnetic wave shielding function area, NS area). The specific process parameters and the measured values ​​of the ...

Embodiment 3

[0069] The carbon filament core-spun yarn of the present invention is used as the weaving yarn, and according to the fuzzy and shielding requirements of the private parts of the human body, an electromagnetic shielding braid using carbon filament core-spun yarn is designed, such as Figure 2ashown. The entire area of ​​the fabric is a two-axis carbon filament core-spun yarn weaving area (2-axis electromagnetic wave shielding functional area, BS area). See Table 2 for specific process parameters and measured values ​​of electromagnetic shielding effectiveness EMSE5 parameters. After the fabric is woven, it can be dyed and finished to make electromagnetic wave shielding and protective clothing. It belongs to the comfortable polyester style and is used for daily wear and human safety protection and privacy protection. It also has high-strength functions.

Abstract

The invention provides an electromagnetic shielding braided fabric of carbon filament covering yarn and application of the electromagnetic shielding braided fabric. The electromagnetic shielding braided fabric comprises braided yarn of a right acclivitous shaft system and braided yarn of a left acclivitous shaft system, and is characterized in that the braided yarn of the right acclivitous shaft system and the braided yarn of the left acclivitous shaft system are partially or completely carbon filament covering yarn. In the invention, the braiding angle and arrangement density of the braided fabric can be changed to obtain a braided fabric which has different electromagnetic shielding properties or has electromagnetic shielding properties in different zones and integrates the electromagnetic shielding advantages of bending arrangement and unbending arrangement of the carbon filament covering yarn. The braided fabric can be used for high-performance protective clothes and comfortable privacy protective clothes with a electromagnetic wave shielding function as well as household and industrial textiles such as covers, sleeves, screens and the like.

Description

technical field [0001] The invention relates to the technical field of electromagnetic shielding, in particular to an electromagnetic shielding braid of carbon filament core-spun yarn and its application. Background technique [0002] With the increasingly widespread application of electrical equipment and communication tools, electromagnetic radiation has become a new kind of pollution. The human body is exposed to electromagnetic radiation for a long time, and the nervous system, cardiovascular system, endocrine system, reproductive system, etc. will be damaged to varying degrees. In order to protect the human body from or minimize the harm of electromagnetic radiation, people shield the source of electromagnetic radiation on the one hand to reduce the amount of radiation. On the other hand, the development of effective protective materials for personal protection, electromagnetic radiation protection fabric is one of them. The fabrics with electromagnetic wave shielding...
