Abstract

The invention discloses a synthesis method of a multifunctional silk fabric fixing agent. The method comprises the following steps: (1) adding 5-8 parts by weight of diethylenetriamine and 3-6 parts by weight of triethylene tetramine into a three-opening flask, stirring, heating up to 65 DEG C at a speed of 5 DEG C / min, dropwise adding 5 parts by weight of ethyl acrylate within 20 minutes, maintaining the temperature at 78 DEG C in the adding process, and reacting for 4 hours; (2) dropwise adding 5 parts by weight of epoxy chloropropane through a constant pressure feeder, meanwhile, dropwise adding 12 parts by weight of distilled water within 35 minutes, maintaining the temperature at 63 DEG C, and reacting for 4 hours; and (3) adding 3 parts by weight of potassium peroxodisulfate, maintaining the temperature at 68 DEG C, reacting for 2 hours, cooling to 35 DEG C, and regulating the pH value to 5 through 30% acetum to obtain the multifunctional silk fabric fixing agent. According to the method disclosed by the invention, the production process is short, process conditions are easy to control, and a small effect is generated on the hand feel of a fabric after the multifunctional silk fabric fixing agent is used.

Description

technical field [0001] The invention relates to a synthesis method of a multifunctional color-fixing agent for silk fabrics. Background technique [0002] The production process of ordinary color fixing agent is long, the process conditions are cumbersome, it is not easy to control, and there will be toxic substances in the production. Contents of the invention [0003] The object of the present invention is to provide a method for synthesizing a multifunctional color-fixing agent for silk fabrics. The production process is relatively short, the process conditions are easy to control, and the hand feeling of the fabric is less affected after use. [0004] In order to achieve the above object, the technical solution of the present invention is to design a synthetic method of a multifunctional color-fixing agent for silk fabrics, comprising the steps of: [0005] 1) Add 5 to 8 parts by mass of diethylenetriamine and 3 to 6 parts by mass of triethylenetetramine into a three-...
