Description

Technical Field

[0001] The utility model relates to a functional fabric, in particular to a functional composite fabric with anti-infrared detection performance, anti-radar detection performance, antibacterial performance and thermal insulation performance, belonging to the field of textile weaving. Background Art

[0002] As thermal infrared detection technology becomes more and more mature, various thermal imaging reconnaissance equipment has appeared on the modern battlefield, such as rotor drones carrying thermal imaging, infrared tracking missiles, etc. The stealth protective clothing used by armored vehicles, tanks and other military vehicles is simply camouflaged in camouflage schemes or environmental colors. It can only camouflage and conceal visible light equipment, but not infrared reconnaissance equipment. It is easy to be discovered under infrared detection, especially when the vehicle generates a lot of heat during the startup process, which is more likely to be detected by infrared equipment and thus hit. In addition, when special operations personnel are in combat, the heat they emit can be easily detected by infrared sensing devices, and the signal waves emitted by radar can easily detect general camouflage. Therefore, fabrics with infrared shielding, infrared absorption and radar electromagnetic wave interference functions have great use value and market space. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a functional composite fabric with anti-infrared detection performance, anti-radar detection performance, antibacterial performance, warmth retention performance and waterproof performance in view of the existing technology.

[0004] The technical solution adopted by the utility model to solve the above-mentioned problems is: an anti-infrared detection, antibacterial and warm-keeping composite fabric, including a fabric main body, the fabric main body includes a skin-friendly antibacterial layer, a far-infrared heating layer and an electromagnetic wave interference layer; the electromagnetic wave interference layer is used as a surface layer, the far-infrared heating layer is used as a middle layer, and the skin-friendly antibacterial layer is used as an inner layer; an anti-infrared layer is arranged on the upper end of the electromagnetic wave interference layer, and a waterproof layer is arranged on the upper end of the anti-infrared layer; the electromagnetic wave interference layer comprises a multi-component coated yarn, the multi-component coated yarn comprises a core yarn, a first coated yarn and a second coated yarn, the first coated yarn is tightly coated on the outer wall of the core yarn, and the second coated yarn is tightly coated on the outer wall of the first coated yarn.

[0005] Furthermore, the fabric body is a double weft structure, the surface weft is 1 / 3 twill, the lining weft is 3 / 1 twill, and the arrangement ratio of the surface weft to the lining weft is 1:1.

[0006] Furthermore, the skin-friendly antibacterial layer, the far-infrared heating layer and the electromagnetic wave interference layer are woven and connected.

[0007] Furthermore, the electromagnetic wave interference layer is bonded to the infrared protection layer.

[0008] Furthermore, the infrared protection layer is bonded to the waterproof layer.

[0009] Furthermore, the anti-infrared layer is a nano-scale catalytic zinc oxide coating. The nano-scale zinc oxide stealth material has a "stealth" effect on infrared and electromagnetic waves, which mainly depends on the characteristics of the nanoparticles in its internal structure: on the one hand, since the size of nanoparticles is much smaller than the wavelength of infrared waves and radar waves, the transmittance of nano-stealth materials to such waves is much higher than that of conventional materials, so that the reflected signals received by infrared detectors and radars are extremely small; on the other hand, the surface area of ​​nanoparticles is 3 to 4 orders of magnitude smaller than that of conventional coarse powder, so the absorption rate of nano-stealth materials to infrared waves and electromagnetic waves is also much higher than that of conventional materials, which greatly reduces the intensity of the reflected signals obtained by infrared detectors and radars, thereby playing a "stealth" role.

[0010] Furthermore, the waterproof layer is an expanded polytetrafluoroethylene membrane layer with a microporous structure.

[0011] Furthermore, the skin-friendly antibacterial layer comprises skin-friendly antibacterial yarn, which is chitosan fiber yarn with a fineness of 30S. Chitosan fiber has a natural antibacterial effect on bacteria. At the same time, chitosan fiber is soft and non-irritating when in contact with the human body, and is more skin-friendly.

[0012] Furthermore, the far-infrared heating layer comprises far-infrared heating polyester, the fineness of the far-infrared heating polyester is 150D, and it contains 3000ppm of aluminum oxide nanopowder, which has extremely strong absorption and reflection capabilities for far-infrared rays. The absorbed far-infrared rays will promote the movement of molecules inside the polyester to form heat energy; the reflected infrared rays emitted by the human body will act on the human body again to play a warming role.

[0013] Furthermore, the core yarn is a polyester-based graphene filament with a fineness of 50D, wherein the graphene content is 3%.

[0014] Furthermore, the first covered yarn is a silver-plated polyester filament with a fineness of 50D.

[0015] Furthermore, the second covered yarn is an ultra-high molecular weight polyethylene filament with a fineness of 50D.

[0016] Compared with the prior art, the advantages of the utility model are:

[0017] (1) The main fabric of the utility model is woven with a double weft structure, and the fabric is endowed with multiple functions by matching the yarns when weaving the main fabric. The surface layer of the main fabric has an electromagnetic wave interference function, the middle layer has a far-infrared heating function, and the inner layer has a skin-friendly and antibacterial function.

[0018] (2) The main body of the fabric of the utility model realizes the absorption and reflection of far infrared rays emitted by the human body and the outside through multi-component coated silk, nano-scale catalytic zinc oxide coating and far-infrared heating layer, and has an excellent far-infrared shielding effect; in addition, the use of silver-plated polyester filament, polyester-based graphene material and nano-scale catalytic zinc oxide coating makes the fabric have excellent electromagnetic wave interference function.

[0019] (3) The second coated yarn of the multi-component coated yarn of the main body of the fabric of the utility model adopts ultra-high molecular weight polyethylene filament, which makes the fabric have excellent wear resistance; the provision of the waterproof layer makes the fabric have excellent waterproof performance and increases the practicality of the fabric.
