Problems solved by technology

But the coloring material of current camouflage camouflage is mainly paint, and paint dyeing is generally used for the camouflage of fixed target, but it exists the problem of feel, rubbing fastness not good, and comfort is poor; In addition, existing camouflage fabric is parked in the open process , Sunlight is directly irradiated on the fabric, because the humidity can change between 0% and 100%, and the combined effect of light (especially ultraviolet light), heat, and humidity will quickly destroy the dye on the fabric and cause the fabric to fade At the same time, it will destroy the fabric itself, resulting in a decline in strength, which will affect the practical performance and hydraulic performance of the fabric.

Embodiment 1

[0046] A preparation process of a camouflage tent cloth, comprising the following steps: the first step, pre-treating the base cloth for dyeing, printing, coating, and setting; the second step, using disperse dyes for dyeing with near-infrared shielding function The base fabric is dyed with the dye solution of the ultraviolet absorber; the third step is to select the printing paste including the disperse dye for printing with near-infrared shielding function to print the dyed base fabric; the fourth step is to use polyamide resin glue Make a primer on the base fabric after printing; the fifth step is to apply PVC whitening to the base fabric after the primer with PVC coating paste; the sixth step is to apply PU to the base fabric after the PVC whitening with polyurethane silver paste Silver surface coating; step 7, padding the base fabric after PU silver surface coating in water-repellent finishing solution, drying and baking. The amount of disperse dye used for dyeing in the ...

Embodiment 2

[0048] The difference from Example 1 is that the amount of disperse dye used for dyeing in the dyeing liquor is 0.5% (owf), and the amount of ultraviolet absorber is 0.5% (owf). The amount of dispersant in each liter of dyeing liquor is 1g, the amount of high-temperature leveling agent in each liter of dyeing liquor is 1g, and the amount of penetration in each liter of dyeing liquor is 2g. In the second step, when dyeing, first put the dye solution and the base cloth at room temperature, adjust the pH of the dye solution to 4.5, then raise the temperature to 50°C in 15 minutes, and then raise the temperature to 125°C in 50 minutes, and then After 80 minutes of heat preservation, cool down and restore the base fabric to be cleaned, and the dyeing solution is a liquor ratio of 1:30. The weight ratio of the disperse dye for printing, the synthetic thickener and the binder is 0.5:60:4. The weight ratio of the polyamide resin coating glue, crosslinking agent and solvent is 100:1:8...

Embodiment 3

[0050]The difference from Example 1 is that the amount of disperse dye used for dyeing in the dyeing liquor is 2.5% (owf), and the amount of ultraviolet absorber is 2.5% (owf). The amount of dispersant in each liter of dyeing liquor is 2g, the amount of high-temperature leveling agent in each liter of dyeing liquor is 2g, and the amount of penetration in each liter of dyeing liquor is 0.5g. In the second step, the dye solution has a liquor ratio of 1:50. The weight ratio of the disperse dye for printing, the synthetic thickener and the binder is 2.5:90:15. The weight ratio of the polyamide resin coating glue, the crosslinking agent and the solvent is 90:1.5:4. When preparing the polyamide resin glue, adjust the viscosity to 10000mPa·S. The process parameters when using polyamide resin glue in the fourth step are as follows: select a sharp-angle scraper, adjust the scraper angle to 115 degrees, adjust the magnetic force of the magnetic roller to 90%, control the temperature i...

Abstract

The invention provides a preparation technology of camouflage cover cloth, which comprises the following steps of: (I) performing pretreatment of base cloth for dyeing, printing, coating and sizing; (II) dyeing the base cloth by use of dyeing liquid including dyeing disperse dye with a near-infrared shielding function and an ultraviolet absorbent; (III) printing the dyed base cloth by use of printing slurry including printing disperse dye with a near-infrared shielding function; (IV) bottoming the printed base cloth by use of polyamide resin glue; (V) performing PVC (polyvinyl chloride) whitewashing of the bottomed base cloth by use of PVC coating slurry; (VI) performing PU (polyurethane) silver-surface coating of the base cloth after the PVC whitewashing by use of polyurethane silver slurry; and (VII) performing padding finishing of the base cloth after the PU silver-surface coating in water-repellent finishing liquid, and then drying and baking. According to the invention, fabric has a near-infrared green shielding function, color fastness to light and high resistance against hydrostatic pressure as well as high water sprinkling degree, the technology is reasonable, and the economic cost is low.

Description

technical field [0001] The invention relates to the textile field, in particular to a preparation process of a camouflage tent cloth. Background technique [0002] With the advancement of science and technology and the continuous improvement of military equipment technology, people have more and more functional requirements for clothing, indoor and outdoor decorative curtains and other fabrics, as well as travel bags, umbrellas, tents and other products with special functions. Higher, therefore, the development of multi-functional outdoor products has been put on the agenda. Among the existing outdoor coated textiles and military outdoor textiles, especially camouflage tents and camouflage clothing as combatants' clothing, not only need to have better camouflage function, but also should have wearing comfort, excellent light resistance and high Water pressure function. But the coloring material of current camouflage camouflage is mainly paint, and paint dyeing is generally...
