Polyamide recycling process and polyamide obtained by recycling process

A polyamide recycling process, comprising following steps:

• adding a polyamide waste material into a mixed solvent to obtain a solution, heating the solution to 50° C. to a reflux temperature of the solution, conducting stirring for dissolution, and then conducting decolorization treatment and filtration to obtain a polyamide solution;
• and adding the polyamide solution into deionized water, precipitating polyamide in the deionized water, and conducting separation to obtain recycled polyamide;
• wherein the mixed solvent comprises, in parts by weight, 10-30 parts of phenol and 15-40 parts of toluene;
• and a weight ratio of the polyamide waste material to the mixed solvent is 1:10 to 1:2,
• wherein a decolorizing agent is added during the decolorization treatment, and a weight ratio of the decolorizing agent to the polyamide waste material is 1:8 to 1:12;
• and the solution is heated to 50° C. to the reflux temperature of the solution, subjected the solution to heat preservation for 0.5-2 hours, cooled the solution to a temperature of less than 50° C., and then filtered the solution to obtain the polyamide solution.
