Baffeta low-temperature neutral-approaching bleaching method

The invention discloses a baffeta low-temperature neutral-approaching bleaching method and belongs to the field of preprocessing of textiles. According to the method, TBCC and H2O2 with the molar ratio of 1: 1.2 are compounded with enough NaHCO3, and a baffeta low-temperature neutral-approaching bleaching system is prepared; a model for optimizing the baffeta bleaching performance of the TBCC/H2O2/NaHCO3 system is established through the response surface analysis method of the statistics and the center composite design, and the model has two main functions of accurately predicting the whiteness value of the TBCC/H2O2/NaHCO3 system to bleached baffeta under the set technological conditions and accurately predicting the technological conditions, needed for reaching a target whiteness value, of the TBCC/H2O2/NaHCO3 system to baffeta bleaching.
