Abstract

The invention discloses a preparation process for double-faced plastic coated waterproof cloth. The preparation process comprises the steps of compounding, grinding, dip coating, drying, high-temperature plasticizing and inspecting; a layer of waterproof coating covers base cloth through different recipes to achieve the goal of water resistance; the waterproof cloth produced by the preparation process disclosed by the invention has good waterproofness, and can be suitable for various occasions.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a preparation process of a waterproof cloth. Background technique [0002] Traditional tarpaulins basically use short fibers such as cotton and chemical fibers as raw materials, and produce canvas through spinning and weaving to make tarpaulins. Therefore, the products are bulky and rough with low strength. The waterproof function of canvas is mainly realized by the density of the fabric. Relying on fabric density to improve the waterproof performance of canvas obviously has inherent shortcomings. Even if the fabric density is tighter, water will still infiltrate the fabric over time. When the water content in the fabric fibers reaches saturation, water seepage will appear. With the development of science and technology, silicone coating has appeared in China to improve the waterproof ability of canvas, but silicone coating also has defects: first, its stability is poor, it is ...
