Problems solved by technology

Although the method of weaving with acrylonitrile fibers or regenerated cellulose fibers and then carbonizing them to form carbon filament fabrics avoids the problem of fluffing of carbon filaments, the fibers will shrink through heat treatment. Shrinkage will deform the fiber, affecting the appearance and smoothness of the fabric, and high temperature treatment will inevitably consume a lot of energy, which is not energy-saving enough

Embodiment 1

[0049] Taking cotton / carbon filament core-spun yarn as the warp and weft yarn, according to the fuzzy and shielding requirements of the private parts of the human body, an electromagnetic shielding woven fabric inlaid with carbon filament core-spun yarn grid is designed, such as Figure 1a shown. The warp and weft yarns are interwoven and the floating lengths are alternately woven to form a dot matrix arrangement structure of interweaving points and floating length points. The warp and weft yarns are interwoven to form a warp and weft interweaving area (DS-WW), which is a high electromagnetic wave shielding functional area; The vertical float length and latitude float length are orthogonal to form the straight float length area (DS-FF), which is a high electromagnetic wave shielding function 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 m...

Embodiment 2

[0051] Taking wool / carbon filament core-spun yarn as the warp and weft yarn, according to the blurring and occlusion requirements of the private parts of the human body, an electromagnetic shielding woven fabric inlaid with carbon filament core-spun yarn square lattice is designed, such as Figure 1b shown. The warp and weft yarns interweave to form a square warp and weft interweaving area, which is a high electromagnetic wave shielding functional area (DS-WW); the warp floating length and weft floating length are orthogonal to form a square straight floating length area, which is a high electromagnetic wave shielding functional area (DS-FF). 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 made into electromagnetic wave shielding and protective clothing after dyeing and finishing. It is wool-style and comfortable, and is used for daily wear, huma...

Embodiment 3

[0053] Taking silk / carbon filament core-spun yarn as the warp and weft yarn, according to the blurring and occlusion requirements of the private parts of the human body, the electromagnetic shielding woven fabric with carbon filament core-spun yarn inlaid with square and rectangular grids is designed, such as Figure 1c shown. Warp and weft yarns interweave to form square and rectangular warp and weft interweaving areas, which are high electromagnetic wave shielding functional areas (DS-WW); warp floating lengths and weft floating lengths are orthogonal to form square and rectangular straight floating length areas, which are high electromagnetic wave shielding functional areas (DS-WW). -FF). 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 made into electromagnetic wave shielding and protective clothing after dyeing and finishing. It is silk-styl...

Abstract

The invention provides an interleaving and floating length mosaic latticed electromagnetic shielding woven fabric and applications thereof. The electromagnetic shielding fabric comprises warp yarns and weft yarns. The fabric is characterized in that all or part of at least one of the warp yarns and weft yarns is composed of carbon filament core-spun yarns; and at least one section of at least onepart of warp yarns composed of the carbon filament core-spun yarns are not interleaved with the weft yarns, at least one section of at least one part of the weft yarns composed of the carbon filamentcore-spun yarns are not interleaved with the warp yarns, or at least one section of at least one part of the warp yarns composed of the carbon filament core-spun yarns are not interleaved with at least one section of at least one part of the weft yarns. The woven fabric provided by the invention has the following advantage: the electromagnetic shielding effect is good and the woven fabric can be effectively used in individual protection.

Description

technical field [0001] The invention relates to the field of electromagnetic shielding materials, in particular to an electromagnetic shielding woven fabric of core-spun carbon filament core-spun yarn and its application. Background technique [0002] With the increasing application of electrical equipment, 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, on the one hand, people shield the source of electromagnetic radiation to reduce the amount of radiation; on the other hand, they develop effective protective materials for personal protection, and electromagnetic radiation protective fabric is one of them. At present, there are mainly two ways to develop fabrics with electro...
