In this paper we simulate the preparation of non-ionic waterborne polyurethane which was prepared by the use of toluene diisocyanate, polyethylene glycol and polypropylene glycol as the main raw materials, which were then dispersed and emulsified in deionized water. In the synthesis stage, we studied the synthesis process, and explore the effects of hydrophilic monomer, polyethylene glycol molecular weight and dosage, NCO/OH, chain extender and solid content on the viscosity and stability of polyurethane aqueous dispersions. Comparing with ionic waterborne polyurethane. The water-based polyurethane has a wide tolerance, which is not affected by acid, alkali or electrolyte, and can be compatible with other ionic compounds, so has certain advantages in textile finishing.
