Abstract
The invention belongs to the textile field, and discloses a waterproof and oil-proof finishing agent. The waterproof and oil-proof finishing agent is mainly prepared from the following raw materials of 12-25 parts of fluorocarbon resin, 0.5-5 parts of penetrant, 0.8-5 parts of cross-linking agent, 1-6 parts of alcohol and 50-90 parts of water. According to the finishing agent prepared in the invention, the finishing agent is free of odor, safe and environment friendly by virtue of proper selection sand dosage selection of the fluorocarbon resin, the penetrant and the cross-linking agent; and meanwhile, a fabric can be processed at a low temperature or in a shade dry condition, so that the fabric has high waterproof and oil-proof functions, and therefore the fabric acquires high anti-fouling performance.
Description
technical field [0001] The invention belongs to the textile field, in particular to a waterproof and oil-proof finishing agent. Background technique [0002] Textiles treated with finishing agents can change the surface properties of the fabrics, thereby endowing the fabrics with special functions, such as making the textiles treated with finishing agents have good waterproof and oil-proof functions. [0003] There are two main types of finishing agents in the prior art. One is water-based finishing agents. The water-based finishing agents are safe and environmentally friendly, have low odor, and are environmentally friendly. The surface of the textile treated with water-based finishing agents has a lotus leaf-like waterproof , Oil-proof performance. However, the water-based finishing agent needs to be baked and dried at a high temperature above 130°C in order to exert its waterproof and oil-proof performance. The other is an organic solvent-based finishing agent, which do...
