Abstract

The invention discloses a preparation method of a waterproof fabric. The preparation method comprises the steps of immersing a fabric liner into a waterproof emulsion, taking out, prebaking, and baking to obtain the waterproof fabric; the waterproof emulsion comprises glacial acetic acid or citric acid, a fluorocarbon resin polymer and water; the concentration of the fluorocarbon resin polymer in the waterproof emulsion is 15-50g / L; and the usage amount of glacial acetic acid or citric acid in the waterproof emulsion is as follows: glacial acetic acid or citric acid is added till the pH value of the waterproof emulsion is 5-6. According to the preparation method, a waterproof film interweaved with the fabric liner is formed by prebaking, baking and then solidifying by adopting the fluorocarbon resin polymer or a modified fluorocarbon resin polymer as a waterproof reagent, so that the integration of the fabric liner and a waterproof layer is realized; the waterproof fabric has the advantages of flexibility and comfortability in use and excellent waterproof property.

Description

technical field [0001] The invention relates to a preparation method of waterproof fabric. Background technique [0002] With the development of the industry, the demand for functional protective gloves such as waterproof, corrosion-resistant, oil-resistant, and solvent-resistant is also increasing. Existing waterproof gloves mainly contain waterproof silicone gloves, and waterproof gloves with a double-layer composite structure of silica gel and fabric lining. [0003] Silicone gloves have excellent waterproof, heat-resistant and non-toxic properties. However, silica gel is not hygroscopic, and it is easy to cause slippage when the hands are sweaty, and it is very inconvenient to take off the belt. In addition, rubber gloves are easy to be scratched when heated. Cutting, cutting and piercing performance is poor. [0004] Through the retrieval of existing documents, it is found that the Chinese invention patent with the application publication number of CN 103653419A discl...
