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 humi

Example Embodiment

[0045] Example one:

[0046] A preparation process of camouflage tent cloth includes the following steps: the first step is to pre-treat the base cloth for dyeing, printing, coating, and setting; the second step is to use disperse dyes including dyeing with near-infrared shielding function The base fabric is dyed with the dye liquor of 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 Base the printed base fabric; the fifth step, use PVC coating paste to whiten the base fabric after the base; the sixth step, use polyurethane silver paste to PU white the base fabric after the PVC Silver surface coating; The seventh step, the base fabric after PU silver surface coating is dipped and rolled in a water-repellent finishing solution, then dried and baked. The amount of disperse dye for dyeing in the dye liquor is...

Example Embodiment

[0047] Embodiment two:

[0048] The difference from the first embodiment is that the amount of disperse dye for dyeing in the dye liquor is 0.5% (owf), and the amount of ultraviolet absorber is 0.5% (owf). The amount of dispersant per liter of dye liquor is 1g, the amount of high-temperature levelling agent per liter of dye liquor is 1g, and the amount of penetrant per liter of dye liquor is 2g. In the second step, when dyeing, first put the dye solution and base cloth at room temperature, adjust the pH of the dye solution to 4.5, then heat up to 50°C in 15 minutes, and then heat up to 125°C in 50 minutes, then After being kept for 80 minutes, the temperature is lowered and the base cloth is restored, and the liquor ratio is 1:30. The weight ratio of the disperse dye for printing, synthetic thickener, and binder is 0.5:60:4. The weight ratio of the polyamide resin coating glue, crosslinking agent, and solvent is 100:1:8. Adjust the viscosity to 8000mPa·S when preparing polyami...

Example Embodiment

[0049] Example three:

[0050] The difference from the first embodiment is that the amount of disperse dye for dyeing in the dye liquor is 2.5% (owf), and the amount of ultraviolet absorber is 2.5% (owf). The amount of dispersant per liter of dye liquor is 2g, the amount of high-temperature levelling agent per liter of dye liquor is 2g, and the amount of penetrant per liter of dye liquor is 0.5g. In the second step, the dye liquor has a liquor ratio of 1:50. The weight ratio of the disperse dye for printing, synthetic thickener and binder is 2.5:90:15. The weight ratio of the polyamide resin coating glue, crosslinking agent and solvent is 90:1.5:4. Adjust the viscosity to 10000mPa·S when preparing polyamide resin glue. In the fourth step, the process parameters when using polyamide resin glue for bottoming are: select an acute angle scraper, adjust the angle of the scraper to 115 degrees, adjust the magnetic force of the magnet roller to 90%, control the temperature of the fro...

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...
