Abstract
The invention discloses a protein fiber low temperature neutral reduction bleaching method. According to the protein fiber low temperature neutral reduction bleaching method, a rare earth chloride anda colorless aromatic compound with a relatively simple structure are subjected to complexing at a certain molar ratio so as to obtain a thiourea dioxide low temperature bleaching catalyst, a bleaching solution is prepared from thiourea dioxide and the thiourea dioxide low temperature bleaching catalyst, and bleaching of protein fiber is carried out at low temperature conditions. The protein fiberlow temperature neutral reduction bleaching method is capable of realizing protein fiber low temperature neutral bleaching, bleaching temperature is reduced, energy consumption is reduced, protein fiber damage is avoided, production efficiency is increased, and the obtained dyed protein fiber is excellent in whiteness and dyeing performance.
