Fluorine-free lyophobic cotton fabric finishing agent and method for tidying cotton fabrics through fluorine-free lyophobic cotton fabric finishing agent

The invention relates to a fluorine-free lyophobic cotton fabric finishing agent and a method for tidying cotton fabrics through the fluorine-free lyophobic cotton fabric finishing agent, and the fluorine-free lyophobic cotton fabric finishing agent and the method are suitable for chemical and textile enterprises. The method comprises the steps that firstly, polyhydric alcohols and an organosilicone monomer are subjected to vacuum water removal, and water in the monomer is removed; secondly, a certain amount of isocyanate, a certain amount of polyhydric alcohols, a certain amount of the organosilicone monomer and a certain amount of a solvent are weighed and evenly stirred, a catalyst is added, and after the temperature is increased to a certain temperature, the reaction is conducted; thirdly, cooling is conducted, and a hydrophilic monomer is added for polymerization; fourthly, a neutralizer is added so that a polymer can be neutralized into salt, water is added for water dispersion,and a product is obtained
