Embodiment

[0028] A graphene-coated metal yarn for radar stealth, comprising a metal yarn body and a graphene layer 3. The metal yarn body is a core-spun yarn including a core yarn and wrapping fibers. The core yarn is a hollow polyester filament 2 . The wrapping fibers are silver-plated wires 1 . The structure of the core-spun yarn can effectively improve the moisture permeability, flexibility and warmth retention of the metal yarn body, and ensure the spinnability of the yarn and the wearability of the textile fabric. The silver-plated metal wire 1 is coated with a metal silver layer on the surface of the matrix filament, and has the characteristics of lower cost, better flexibility and better wrinkle recovery than pure metal wire. The thickness of the metallic silver layer is controlled at 5-10 μm. In order to improve the strength of the metal yarn body and ensure the bonding strength of the graphene layer 3, the metal yarn body is 2-8, twisted and plyed to form a twisted yarn. Pr...

Embodiment 2

[0035] The radar stealth with structure identical with embodiment 1 is coated with metal yarn with graphene, for the preparation method of this radar stealth with graphene coated with metal yarn, may further comprise the steps:

[0036] In step 1, the metal yarn body is parallel-twisted by a twisting machine to form a twisted yarn.

[0037] Step 2, add graphite powder to the well-stirred concentrated sulfuric acid and sodium nitrate solution, then add potassium permanganate, stir for 30-50 minutes, let stand for stratification, remove the lower layer, add 30% hydrogen peroxide solution, and react , and then pickled, washed with water, sonicated for 2 hours, and then centrifuged to obtain graphene oxide, which was prepared into a 10 g / L graphene oxide solution. The twisted yarn was processed by a sizing machine, the graphene oxide solution was put into the immersion tank, the speed of the sizing machine was 6r / min, and the temperature in the drying zone was 60°C; the twisted ya...

Abstract

The invention discloses a graphene plated metal yarn for radar stealth and a manufacturing method thereof. The graphene plated metal yarn comprises metal yarn bodies and a graphene layer. Each metal yarn body is a core-spun yarn. A core yarn is a hollow polyester filament. A wrapped fiber is a silver-plated metal wire. The silver-plated metal wire is formed through plating a metal silver layer ona matrix filament surface. There are two to eight metal yarn bodies which are twisted to form a twisted yarn. The graphene layer is plated on the outer surface of the twisted yarn. The manufacturing method is simple, the rate of finished products is high, the manufactured graphene plated metal yarn has good moisture permeability and a good heat insulation effect. A yarn strength is 12-18cN / tex, and the strength requirement of garment yarns is guaranteed. At the same time, the bonding strength of the graphene layer and the twisted yarn is good and water resistance performance is good. And the dielectric property changes of metal yarn body surfaces are enhanced through the graphene layer, a radar stealth frequency band is widened, and the environmental stability of the metal yarn bodies is improved.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a graphene-coated metal yarn for radar stealth and a preparation method thereof. Background technique [0002] Radar stealth technology is of great military significance and has been used in stealth fighter jets, stealth missiles, stealth submarines, stealth tanks and other weapons. Combine aerospace technology, military technology and textile technology to develop microwave-absorbing protective clothing, professional protective clothing for personnel in special environments, and also develop concealed covering fabrics for military equipment and combat uniforms for soldiers, etc., which has a good development prospect. [0003] At present, metal yarns (mostly stainless steel fiber yarns) are mainly used for radar stealth. The metal yarns used for radar stealth have defects such as poor clothing, low stealth efficiency, and poor environmental resistance. [0004] 1. The radar stealth comb...
