Problems solved by technology

Due to the poor fastness of the coating and the fabric, poor wear resistance, and affect the wearing comfort of the human body, all countries are vigorously developing dyes with near-infrared stealth functions, mainly looking for dyes that are relatively close to the natural background reflection spectrum curve. Make the reflection spectrum curve of the dyed fabric coincide with the reflection spectrum curve of the background as much as possible

Embodiment 1

[0030] Weigh 2.2% of reduced golden yellow RK, 0.4% of reduced brilliant blue RCL, and 0.4% of reduced brilliant green FFB into a clean Erlenmeyer flask A. Restore with a dry cylinder method, dilute with a small amount of distilled water (5ml), add 2 / 3 of the amount of caustic soda (NaOH) and sodium bicarbonate (NaOH) 2 S 2 o 4 ), add water to make the dye bath 1 / 4 of the total amount of the dye solution, and stir. Take another clean Erlenmeyer flask B, add 3 / 4 of the total amount of distilled water required and the remaining 1 / 3 of the amount of caustic soda. Put the two Erlenmeyer flasks into a constant temperature water bath at the same time, raise the temperature to 60°C, and fully reduce the dye for 8-10 minutes to make a leuco dye solution. Then add the remaining 1 / 3 amount of hydrosulfite into conical flask B to fully dissolve, then add it into the dye solution (conical flask A) that has been dried and reduced, and stir evenly.

[0034] Weigh reduced golden yellow RK 2%, reduced brilliant blue RCL 0.25%, reduced brilliant blue BC 0.25%, reduced brilliant green FFB 0.5% in a clean Erlenmeyer flask A. Restore with a dry cylinder method, dilute with a small amount of distilled water (5ml), add 2 / 3 of caustic soda, sodium hydrosulfite, and add water to make the dye bath 1 / 4 of the total amount of the dye solution, and stir evenly. Take another clean Erlenmeyer flask B, add 3 / 4 of the total amount of distilled water required and the remaining 1 / 3 of the amount of caustic soda. Put the two Erlenmeyer flasks into a constant temperature water bath at the same time, raise the temperature to 60°C, and fully reduce the dye for 8-10 minutes to make a leuco dye solution. Then the remaining 1 / 3 amount of hydrosulfite (Na 2 S 2 o 4 ) into the Erlenmeyer flask B to fully dissolve, and then add it into the dried and reduced dye solution (Elenmeyer flask A), and stir evenly.

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 [0001] The invention belongs to the field of preparation of infrared stealth cotton textiles, and in particular relates to a preparation method of near-infrared stealth cotton textiles. Background technique [0002] Camouflage cotton cloth is often used in military camouflage clothing and coverings, such as beach camouflage, forest camouflage, green camouflage, etc. However, with the development and progress of science, high-tech reconnaissance methods are more and more used in the military, and the ordinary camouflage colors designed according to the surrounding environment can no longer achieve good camouflage. Reconnaissance can detect general camouflage effects. As a result, anti-infrared camouflage fabrics have been developed for anti-infrared reconnaissance. [0003] Infrared is a kind of electromagnetic radiation. The German Industrial Standard DIN5031 classifies electromagnetic radiation in the wavelength range of 0.78 to 1000 μm as infrared radiati...
