Problems solved by technology

When the tent is exposed to heavy rain, the rainwater will slowly conduct moisture into the fabric (coated surface) through the fabric, and there will be moisture inside, so the rainstorm resistance performance is poor
At the same time, this technical method uses a coating slurry to evenly coat the surface of the base fabric in a dry coating method. It is uncertain how much slurry needs to be coated for different thickness of fabrics. For tent fabrics, precision gluing at the splicing part of the tent body It is also difficult to realize, so the fabric prepared by this technical means is not suitable for making tents, and it is not suitable for realizing high water resistance against heavy rain
[0010] CN 202156066 U discloses a waterproof and moisture-permeable tent fabric. The disclosed content is to coat the polyester fabric with an anti-seepage layer. The material of the anti-seepage layer is polyurethane, and the water resistance can reach up to 8970㎜. The tent fabric prepared by this technical means is rainproof Poor, and not flame retardant

Description

technical field [0001] The invention relates to a processing method for tent fabrics, in particular to a processing method for realizing high waterproof, moisture-permeable and flame-retardant fabrics through a coating processing method. Background technique [0002] The most basic requirement for tent fabrics is waterproofness. Generally, the waterproofness of 300mm can meet the requirements of beach tents or sunshade tents; the waterproofness of 800-1200mm can meet the requirements of simple camping tents; the waterproofness of 1500- 2000mm can meet the requirements of mid-range tents; water resistance above 3000mm can meet the requirements of professional tents. Tent fabrics for special use environments must not only have higher water resistance, but also have special requirements such as moisture permeability, flame retardancy, lightness, and cold resistance. [0003] Water resistance refers to the ability of a fabric to completely resist the penetration of water. [0...
