Coating technology for tent cloth

Abstract

The invention discloses a coating technology for a tent cloth. The coating technology comprises the following steps that 1, bottoming is performed on a fabric base cloth by adopting a PA adhesive; 2, PVC whitening is performed on the bottomed fabric base cloth by adopting PVC coating slurry; 3, PU silver surface coating is performed on the PVC-whitened fabric base cloth by adopting PU silver slurry. Compared with the prior art, a fabric base cloth fabric not only has the functions of the high color fastness to light and the high resistance to the static water pressure, but also has the higher water splashing degree effect, the technology is reasonable, and the economic cost is low.

Description

Background technique [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 f...

AI Technical Summary

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
