Problems solved by technology

However, the coloring material of current camouflage camouflage is mainly paint, and paint dyeing is generally used for camouflage of fixed targets, but it has the problems of poor hand feel and rubbing fastness, and poor comfort
In addition, when the existing camouflage fabrics are parked in the open air, sunlight directly irradiates the fabrics, and since the humidity can vary between 0-100%, and the comprehensive effect of light (especially ultraviolet light), heat, and humidity, it will Destroy the dye on the fabric faster, causing the fabric to fade quickly, and at the same time destroy the fabric itself, resulting in a decrease in strength, thus affecting the practical performance and water pressure performance of the fabric
Moreover, the textiles used for direct coating are all interwoven by warp and weft yarns, and the surface of the fabric is extremely uneven. Direct coating will inevitably cause diffuse reflection of the coating film on light.
The existing technology is to calender the fabric first, flatten the warp and weft yarn interlacing points as much as possible, and then coat. The worse the peel strength between the coating film and the fabric

Embodiment 1

[0011] Embodiment 1 A kind of coating process of tent cloth, comprises the following steps, the first step, adopts PA glue to carry out priming to fabric base cloth; White; the 3rd step, carry out PU silver surface coating to the fabric base cloth after PVC is coated with white with PU silver paste, described PA glue comprises PA coating glue, crosslinking agent, solvent, and PA coating glue, crosslinking The weight ratio of agent and solvent is 70-11:1-3:3-9.

[0012] Further, the preparation process of the PA glue is: add the solvent into the crosslinking agent and mix thoroughly, then add it to the coating glue and stir, while stirring, add toluene to adjust the viscosity to 7000-9000mPa. Leave for 40 minutes.

[0013] Further, the PVC coating slurry includes PVC resin, plasticizer, and heat stabilizer, and the weight ratio of PVC resin, plasticizer, and heat stabilizer is 95:95:0.5-3, and the PVC coating slurry Also includes white paint.

[0014] Further, the preparatio...

Abstract

A disclosed coating technology for cover cloth comprises the following steps: first step, priming fabric base cloth by employing PA glue; second step, performing PVC whitewashing on the primed fabric base cloth by PVC coating slurry; and third step, performing PU silver face coating on the fabric base cloth subjected to PVC whitewashing by PU silver paste. Compared with the prior art, the coating technology enables the fabric base cloth to have high color fastness to light and high hydrostatic-pressure resistance as well as relatively water sprinkling effect, and is reasonable in technology and low in economic cost.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a coating process for tent cloth. Background technique [0002] 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 present 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, when the existing camouflage fabrics are parked in the open air, sunlight directly irradiates the fabrics, and since the humidity can vary between 0-100%, and the comprehensive effect of light (especially ultraviolet light), heat, and humidity, it will Destroy the dye on the fabri...
