Abstract
The invention relates to a method for preparing a near infrared stealthy cotton textile, which comprises the following steps: a reducing dye is weighed and put into a clean conical beaker A; distilled water, NaOH and vat powder Na2S2O4 are added; then distilled water which accounts for one fourth of the total amount of a needed dyeing liquor is added for stirring evenly; another conical beaker B is taken out, and the distilled water which accounts for three fourths of the total amount of the needed dyeing liquor and NaOH are added; the two conical beakers are placed into a constant-temperature water bath, and the temperature is increased to 60 DEG C to ensure that the dye is reduced into a leuco dyeing liquor; then the vat powder Na2S2O4 is added into the conical beaker B to be dissolved; the mixture is added into the conical beaker A to stir evenly; after the configuration of a leuco dye bath is finished, mercerized bleached cotton cloth which is moistened in water is extruded to be dried and then is added into the dye bath with a temperature of 60 DEG C to be dyed for 30 minutes; after the dyeing is finished, the test sample is taken out, oxidized by air, washed by cold water, soap boiled and dried; and a waveband of between 400 and 1400nm is taken as a test waveband to perform the test of a reflectance curve to the sample. The near infrared stealthy cotton textile has the advantages of comfortable wearing, good air permeability, and good various color fastnesses.
Description
Technical field
The invention belongs to the preparation field of infrared stealth cotton textiles, particularly relate to a kind of preparation method of near-infrared concealed cotton textiles.
Background technology
The camouflage color cotton is usually used in the camouflage clothes of army and covering or the like, such as sandy beach camouflage color, forest camouflage, greenery patches camouflage color etc.But, along with the reach of science and progress, high-tech reconnaissance means are applied to military affairs more and more, and the common camouflage color that designs along with the surrounding environment difference can not reach good camouflage, utilizes this technology of infrared ray just to scout and can track down general camouflage painting effect.Thereby develop and the anti-infrared camouflage fabric, be used for anti-infrared ray and scout.
Infrared ray is a kind of electromagnetic radiation, and Deutsche industry norm (DIN) DIN5031 divides the electromagnetic radiation of 0.78～1000 mum wavelength scope into infra-red radiation.At present, about the not strict regulation of the division of infrared ray section.In spectroscopy, infra-red radiation is divided into three zones according to the mechanism difference that infra-red radiation produces by wavelength: the near infrared region of 0.75-2.5 μ m, the middle infrared of 2.5-25 μ m, the far-infrared band of 25-1000 μ m.Also have the scholar that 0.78-1.4 mu m waveband infrared ray is divided into near-infrared, infrared during the 1.4-3 mu m waveband divides into, the 3-1000 mu m waveband divides far infrared into.And in the infrared technique field,, usually the 0.75-3 mu m waveband is divided into near-infrared according to the propagation characteristic of infra-red radiation in earth atmosphere, and infrared during the 3-6 mu m waveband divides into, the 6-15 mu m waveband divides far infrared into, and the 15-1000 mu m waveband divides utmost point far infrared into.Wave band detection range of the present invention is 0.4-1.4 μ m.
At present at home, the infrared stealth coating technology has reached practicability, in being widely used in producing.Because it is bad that coating and fabric combine fastness, wear no resistance, and influence the human body snugness of fit, therefore, each state is is all researching and developing the dyestuff with near-infrared concealed function energetically, mainly be to seek and the more approaching dyestuff of natural background reflectance spectrum curve ratio, the reflectance spectrum curve after the textile dyeing is overlapped with the reflectance spectrum curve of background as far as possible.The present invention is by the analysis to dye structure and performance, filter out reducing dye with infrared stealth function, as Vat Brilliant Green FFB, vat yellow 5GF or the like, these dyestuffs have lower near infrared reflectivity, simultaneously can satisfy the requirement of visual camouflage, and have stronger fast light and color fastness to washing.Mixed assorted ratio between each dyestuff of primary study afterwards reduces the emissivity of fabric face, as far as possible to reach the purpose that is complementary with greenery patches of living in background.
Summary of the invention
Technical problem to be solved by this invention provides a kind of preparation method of near-infrared concealed cotton textiles, and near-infrared concealed cotton textiles of the present invention is comfortable and easy to wear, good permeability, and every COLOR FASTNESS is good.
