Production method of thermal transfer printing base paper

The invention discloses a production method of thermal transfer printing base paper. The method comprises raw material pulping and washing and concentrating technologies. The production method is characterized by comprising the steps that raw materials are subjected to circulating intermittent pulping in a pulper, biological enzyme and sodium hydroxide are added simultaneously to achieve sufficient fiber softening and defibering, and raw material broken pulp is obtained; the pulp obtained through pulping is washed and then concentrated; meanwhile, a press felt is optimized and used. In this way, according to the production method of the thermal transfer printing base paper, chemical substances affecting transfer printing dyeing can be removed from the pulp, and therefore recessive white spots of transfer printing paper are reduced.
