This thesis the toluene diisocyanate ester ( TDI ) , polyethylene glycol (PEG), polypropylene glycol (PPG), dimethylol propionic acid (DMPA), diethylene triamine (DETA) , epichlorohydrin (ECH) and the amino silicone aminoethylaminopropyl as raw material , the use of acetone prepared an amino silicone modified waterborne polyurethane resin (WPU) fixing agent , and the test for reactive dyeing of cotton fabric various color prison degree of shade changes and soft performance . In addition, the production process of the production workshop set annual production capacity of 5400 tons of the fixing agent products for which an application performance better product laboratory preparation process and formulation design . This paper examines a polyether polyol types and relative molecular mass , the added amount of the dimethylol propionic acid , solvent types and the addition amount of the prepolymerized reaction temperature and time , and the R value ( R = -NCO/-OH ) expansion the kind and amount of the chain extender , the chain extension reaction temperature and time, and the feeding method , the added amount of the amino-silicone , quaternary ammonium ion - positive group and the reactive group (-Cl) introduction of , and the degree of the aqueous polyurethane emulsion and latex to finalize the preparation of amino silicone modified waterborne polyurethane resin fixing agent emulsion film performance , processes and formulations . And Fourier transform infrared spectroscopy were used to characterize the structure of amino silicone modified waterborne polyurethane resin prepared fixing agent . Fixing process with a dip in the application of the fixing agent prepared experiments , a rolling , 150 ℃ baking three minutes , the amount of fixing agent to 30g / L . Experimental results show that : The papers prepared amino silicone modified waterborne polyurethane resin fixing agent blend of organic silicon compounds , especially washable up to 4-5 grade color fastness , moisture friction color fastness up to 4 is better than the merchandise fixing agent fixing effect , help to solve the reactive dyes on the market , dark-colored cotton fabric color fastness to washing and moisture friction color fastness problems with certain market development prospects.
