Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to vinylon for producing various camouflaged articles such as camouflage clothes, tents, tents, vehicle holo, personal equipment, etc. having a camouflage pattern in the infrared region. The present invention relates to a camouflage processing method for a woven fabric.

[Conventional technology]

In general, camouflage clothing and the like need to have no contrast with surrounding objects. That is, in the visible light region, for example, if a red object is present in a place where the surroundings are yellow, the contrast is clear and conspicuous, so that the camouflage clothing or the like must be a camouflage pattern having no contrast with the surroundings.

Therefore, camouflage clothing worn by SDF members is given a camouflage pattern that takes into account the color of natural objects such as various plants and rocks in Japan in the wavelength region of visible light.

[Problems to be solved by the invention]

However, this camouflage suit has a camouflage pattern that takes into account only the colors of natural objects such as various plants and rocks in Japan in the wavelength range of visible light. The infrared detection method, which is one of the methods, has a drawback that the infrared reflectance of the camouflage suit is different from the rocks of the surrounding plants and is easily found. There are various types of infrared detection methods, such as infrared photography and infrared night mirroring, all of which have been widely used in recent years because they can be effectively detected even in fog or at night. And generally 600-860nm infrared, or 1000-1200
Detects using nm infrared.

With the development of such infrared detection methods, in order to respond to this, camouflage uniforms using pigments corresponding to infrared rays of 600 to 860 nm or camouflage uniforms using dyes and pigments corresponding to infrared rays of 1000 to 1200 nm, etc. Is used. But 600
There is no camouflage clothing corresponding to the region extending to ~ 1200 nm, and pigments are often fixed to fabrics such as cotton mainly with resin, and the hand has a drawback that the feel is rough and hard, and the wind by the dye of vinylon-based fabrics At present, no camouflage uniform or the like imitating infrared rays has been developed yet.

[Means and actions for solving the problem]

In view of the current situation, the present invention provides a vinylon-based fabric with 60
A vinylon-based camouflage pattern having a different infrared reflectance of three stages of 20% or less, 20 to 40%, and 40% or more in the range of 0 to 1200 nm by dyeing using the following vat dyes. It is a camouflage processing method for textiles.

at Brown 1 The woven fabric used in the present invention is composed of vinylon-based fibers alone or vinylon-based fibers and other fibers. Various types of vinylon-based fibers are used as vinylon-based fibers. Other preferred fibers include cellulose fibers such as cotton and hemp, recycled fibers such as rayon and polynosic, and synthetic fibers such as nylon and polyester. The woven fabric composed of vinylon-based fibers and other fibers is a blended yarn of vinylon-based fibers and other fibers, a woven fabric using a twisted yarn, or a cross-woven product of vinylon-based fibers and other fiber yarns.

The pattern formed on the vinylon-based woven fabric is divided into at least three regions on the entire surface of the woven fabric and dyed by printing or the like with a dye or a blend of dyes having different infrared reflectances. In order to dye in a dark color, it may be dyed by dyeing prior to printing. It is desirable that this pattern forms a camouflage pattern even in the visible light region.

The dye to be used is a vat dye which can be dyed in a strong color even in the visible region of vinylon fabric and can be dyed in a dark color, and a sulfur dye can also be used.

The dye used is a dye or a blend of dyes having different infrared reflectances in the region of 600-1200 nm.

It is desirable that the camouflage pattern shows three levels of reflectance of 20% or less, 20 to 40%, and 40% or more in a wavelength region of 600 to 1200 nm. This is the result of measuring the infrared reflectance of leaves, rocks, etc. of trees in both wavelength ranges from 600 to 1200 nm.
In the wavelength region of 200 nm, 20% or less, 20-40%, 40%
% Or more in three stages. That is,
In the wavelength region of 600 to 1200 nm, the following reflectance (%) is shown.

m) Light green ground dyeing was performed in a dye bath having the following composition.

Next, pad chemical steam treatment under the following conditions,
Oxidation, soaping and hot water washing were performed to develop color.

Next, the woven fabric was divided into four color regions, and three regions other than the ground color light green were dyed black, brown, and dark green by printing according to the following formulation.

Next, high temperature steam, water washing, oxidation, soaping / hot water washing, and drying were performed.

High temperature steam 105 ℃, 12min The obtained dyed cloth exhibited the following infrared reflectance (%).

In addition, since it is based on a processing method using a vat dye of a vinylon-based fabric, it has a soft feel, is excellent in air permeability, moisture absorption, robustness, and disaster prevention, and is also excellent in washing resistance to the infrared camouflage effect.
