(2) chemical modification of polyglutamic acid: adding water into pretreated polyglutamic acid and decyl glucoside, stirring, dissolving completely, then dropwise adding 98% concentrated sulfuric acid to adjust the pH value to 4, heating to 60-70 ℃, keeping the temperature, stirring, reacting, concentrating under reduced pressure to obtain paste, naturally cooling the paste to room temperature, then feeding the paste into a freeze dryer, drying the obtained solid, and micronizing to obtain modified polyglutamic acid;
(3) preparing auxiliary materials: heating cetyl alcohol to molten state, stirring under heat preservation, adding allyl glycidyl ether and isooctyl palmitate, and mixing to obtain adjuvants;
(4) preparation of leveling agent: and (3) uniformly mixing the prepared modified polyglutamic acid and auxiliary materials, heating to 110-120 ℃ at a heating rate of 5 ℃/min, stirring for 5-10 min at a heat preservation temperature, cooling to-10-0 ℃ at a cooling rate of 5 ℃/min, stirring for 5-10 min at a heat preservation temperature, and naturally returning to room temperature to obtain the leveling agent.
2. The high temperature leveling agent special for the ultrafine fiber fabric according to claim 1, wherein: the polyglutamic acid is water treatment grade polyglutamic acid.
3. The high temperature leveling agent special for the ultrafine fiber fabric according to claim 1, wherein: the mass ratio of the polyglutamic acid to the decyl glucoside to the cetyl alcohol to the allyl glycidyl ether to the isooctyl palmitate is 50: 10-20: 1-10.
4. The high temperature leveling agent special for the ultrafine fiber fabric according to claim 1, wherein: the auxiliary material also comprises nanometer rubber powder, and the mass ratio of the nanometer rubber powder to the polyglutamic acid is 1-10: 50.
5. The high temperature leveling agent special for the ultrafine fiber fabric according to claim 4, wherein: the nanometer rubber powder is prepared from gas-phase silicon dioxide, PEG-60 hydrogenated castor oil and hydrolyzed polymaleic anhydride, and the preparation method comprises the following steps: fully mixing the gas-phase silicon dioxide, the PEG-60 hydrogenated castor oil and the hydrolyzed polymaleic anhydride, then granulating by a dry method to prepare particles of 60-80 meshes, and finally preparing the particles into nano powder by a nano grinder to obtain the nano rubber powder.
6. The high temperature leveling agent special for the ultrafine fiber fabric according to claim 5, wherein: the mass ratio of the fumed silica to the PEG-60 hydrogenated castor oil to the hydrolyzed polymaleic anhydride is 3:2: 0.5.
