Sulfur treatment in three ways: First, sulfur smoked law, will Guatiao placed in a sealed container at the bottom of the combustion generates sulfur dioxide fumigation, the amount of sulfur Guatiao 0.3%; the second is to be immersed in Asia Guatiao aqueous sulfuric acid (concentration of 0.2 to 0.3%) for 30 minutes; the third is added to the pre-color protection program, so-called pre-color protection refers to the traditional method of color protection before a short soak protecting color liquid with a high concentration (1% sodium bisulfite) ( 5 minutes).
