preparation example Construction

[0033] The present invention also provides a preparation method of the near-infrared camouflage masterbatch described in the above scheme, which includes the following steps: mixing functional powder with chemical fiber and performing melt extrusion to obtain the near-infrared camouflage masterbatch.

[0034] In the present invention, the chemical fibers are preferably chemical fiber chips, specifically polyester chips or nylon chips; the melting temperature of the screw extrusion is preferably 280°C, and the melt extrusion is preferably twin-screw extrusion; During the extrusion process, the chemical fiber slices are melted and fully mixed with the functional powder, and the near-infrared camouflage masterbatch is obtained after extrusion.

[0035] In a specific embodiment of the present invention, it is preferable to carry out screw extrusion of each functional powder separately with chemical fiber slices to obtain a variety of near-infrared camouflage masterbatches. Accordin...

Embodiment 1

[0050] Aluminum powder with a particle size of 1 μm is mixed with polyester chips for twin-screw extrusion at a melting temperature of 280°C to produce aluminum powder polyester masterbatches with a mass fraction of aluminum powder of 20%;

[0051] Mix zinc oxide with a particle size of 500nm and polyester chips for twin-screw extrusion at a melting temperature of 280°C to produce a zinc oxide polyester masterbatch with a mass fraction of zinc oxide of 40%;

[0052] Take 200g of aluminum powder polyester masterbatch, 400g of zinc oxide polyester masterbatch, mix with 9.4kg of polyester masterbatch, and spin to obtain No. 1 fiber.

[0053] Take 400g of aluminum powder polyester masterbatch and 300g of zinc oxide polyester masterbatch, mix them with 9.3kg of polyester masterbatch, and spin to obtain No. 2 fiber.

[0054] Take 600g of aluminum powder polyester masterbatch and 200g of zinc oxide polyester masterbatch, mix them with 9.2kg of polyester masterbatch, and spin to obtai...

Embodiment 2

[0065] The rare earth-containing oxide with a particle size of 1-3 μm is mixed with polyester chips for twin-screw extrusion, and the melting temperature is 280 ° C to produce a rare earth-based polyester masterbatch with a mass fraction of rare earth oxides containing 10%;

[0066] 1 kg of rare earth-based polyester masterbatch, 9 kg of polyester masterbatch, mixed and spun to obtain No. 6 fiber, the spinning temperature is 280 ° C, the fiber specification is 15D, and the mass fraction of rare earth oxide in No. 6 fiber is 1%.

[0067] The No. 6 fiber was warp-weft-woven to obtain the No. 6 fabric. The near-infrared reflectance of the No. 6 fabric was tested, and the results showed that the near-infrared reflectance of the No. 6 fabric at 750-1200nm was 9-15%.

Abstract

The invention relates to the technical field of camouflage materials, and provides a near-infrared camouflage master batch and a preparation method thereof, a near-infrared camouflage fiber and a fabric. According to the invention, functional powder is doped into the polyester to obtain the near-infrared camouflage master batch, and the master batch can be used for preparing fibers with a camouflage effect. The camouflage fabric is prepared from the fiber, wherein ingredients of a dye do not need to be blended, the fiber does not need to be complexly dyed, the camouflage effect is good, and the camouflage effect is not affected by a dyeing method. Furthermore, the near-infrared reflectivity of the near-infrared camouflage fabric can be regulated and controlled by adjusting the variety and the addition amount of the functional powder, so the camouflage fabric suitable for different environments is obtained.

Description

technical field [0001] The invention relates to the technical field of camouflage materials, in particular to a near-infrared camouflage masterbatch and a preparation method thereof, as well as near-infrared camouflage fibers and fabrics. Background technique [0002] With the continuous advancement of science and technology, a variety of high-end reconnaissance and guidance equipment have been put into military applications, making modern reconnaissance and targeting technology develop to a very high level. Corresponding anti-reconnaissance, camouflage equipment to make corresponding improvements become particularly important. Camouflage technology can reduce the probability of military targets being discovered by infrared, radar and other reconnaissance equipment by controlling the voice of personnel, the infrared characteristics of equipment surfaces, and the reflection frequency of light and radar waves. [0003] Compared with other detection technologies, infrared dete...
