Embodiment 1

[0016] The invention relates to a whitening process of camouflage tent fabric. Before coating, PVC coating paste is used to whiten the fabric after priming. The PVC coating slurry includes PVC resin, plasticizer and thermal stabilizer, and the weight ratio of PVC resin, plasticizer and thermal stabilizer is 100:100:0.5-4. The PVC coating paste also includes white paint. The weight ratio of the PVC resin, plasticizer and stearate is 100:100:0.5. Described plasticizer comprises DOP, DBP, and the weight ratio of DOP, DBP is 1: 1, and described thermal stabilizer is stearate, and described stearate comprises zinc stearate, barium stearate, The weight ratio of calcium stearate to zinc stearate, barium stearate and calcium stearate is 0.5:1:1.2. The preparation process of the PVC coating slurry is as follows: first add a part of the plasticizer to the stearate and the white paint, stir well, then pour it into the mixer together with the PVC resin, then add the remaining plasticize...

Embodiment 2

[0018] The difference from Example 1 is that the PVC coating slurry includes PVC resin, plasticizer, and heat stabilizer, and the weight ratio of PVC resin, plasticizer, and heat stabilizer is 100:100:4. The preparation process of the PVC coating slurry is as follows: first add a part of the plasticizer to the stearate and the white paint, stir well, then pour it into the mixer together with the PVC resin, then add the remaining plasticizer, stir well Finally, grind once with a three-roller mill, and finally stir the ground ingredients for another 10 minutes, and let stand for 30 minutes or vacuumize for defoaming treatment. The process parameters of PVC white coating are: select sharp-angle scraper, adjust the scraper angle to 125 degrees, adjust the magnetic force of the magnetic roller to 100%, control the oven temperature to 190°C, and the plasticizing time to 3 minutes. The PU silver paste includes single-component polyurethane, aluminum silver paste, methyl ethyl ketone,...

Embodiment 3

[0020] The difference from Example 1 is that the PVC coating slurry includes PVC resin, plasticizer, and heat stabilizer, and the weight ratio of PVC resin, plasticizer, and heat stabilizer is 100:100:0.5. The preparation process of the PVC coating slurry is as follows: first add a part of the plasticizer to the stearate and the white paint, stir well, then pour it into the mixer together with the PVC resin, then add the remaining plasticizer, stir well Finally, grind once with a three-roller mill, and finally stir the ground ingredients for another 5 minutes, and let stand for 30 minutes or vacuumize for defoaming treatment. The process parameters of PVC white coating are: select sharp-angle scraper, adjust the scraper angle to 115 degrees, adjust the magnetic force of the magnetic roller to 90%, control the oven temperature to 170°C, and the plasticizing time to 2 minutes.

Abstract

The invention provides a whitewashing process of camouflage cover cloth. Before coating, fabric is subjected to PVC (polyvinyl chloride) whitewashing by use of PVC coating slurry. According to the invention, fabric has high color fastness to light and high resistance against hydrostatic pressure and 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 whitening process of a camouflage tent cloth. Background technique [0002] 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 directly irradiates 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, causing the fabric to fade quickly , At the same time, it will also damage the fabric itself, resulting in a decrease in strength, which will affect the practical performance and hydraulic performance of the fabric. Generally, the textiles used for direct coating are interwoven by warp and weft yarns, and t...
