The invention discloses a fluorine-free waterproof finishing agent and its preparation and application method, and relates to the technical field of fabric finishing. The key points of the technical solution are a fluorine-free waterproof finishing agent, a fluorine-free waterproof finishing agent, expressed in parts by weight , including the following components: 2-4 parts of fluorine-free water repellent, 0.1-0.3 parts of crosslinking agent, 1-2 parts of penetrating agent, 1-2 parts of defoaming agent and 45-55 parts of water; The water repellant includes fatty alcohol polyoxyethylene ether. The invention has excellent water-repellent performance through the low surface properties of the fluorine-free water repellent agent, and the fluorine-free water-repellent agent prepared by combining it with a crosslinking agent, a penetrating agent and a defoaming agent can spread rapidly on the fiber surface Film formation can effectively reduce the friction coefficient of the fiber surface and improve the waterproof performance of the fiber fabric. |
