In step c, be directly to add in the protein solution through the polyvinyl alcohol of washing, under 60 ℃～98 ℃ temperature, make their blend copolymerization, 1.5～4 hours time, make the concentration that contains protein and polyvinyl alcohol and be 8%～14% or 15%～38% spinning solution;
In step e, spinning solution is a standing and defoaming 3～8 hours under 50～80 ℃ of temperature, normal pressure, or in 30～40 ℃ of temperature, vacuum standing and defoaming 3～8 hours.
5, method according to claim 4, it is characterized in that: among the described step c, the concentration that contains protein and polyvinyl alcohol in the spinning solution is 15%～38%, in step e, after entering the spinning program, adopt the spinning technique of dry-jet wet-spinning to make soylon.
6, method according to claim 4, it is characterized in that: among the described step c, the concentration that contains protein and polyvinyl alcohol in the spinning solution is 20%～38%, in step e, after entering the spinning program, adopt dry-spinning process to make soylon.
