Abstract
The invention discloses yellow lignocellulose which comprises the following components in parts by weight: 60-70 parts of pure natural wood flour, 20-25 parts of water, 10-15 parts of hydrogen peroxide with the concentration of 27.5%, 1.0-1.5 parts of caustic soda flakes, 0.03-0.04 parts of a whitener, 0.2-0.25 parts of reactive yellow, 0.06-0.07 parts of reactive indigos and 0.06-0.07 parts of a color fixer. A preparation method for the yellow lignocellulose comprises the following steps: adding the components into a reaction pot, carrying out dry dyeing and mixing for 50 minutes to 1.2 hours, discharging from the pot for air-curing, carrying out online grinding by a ball mill when the water content is less than 20%-30%, screening through a synthetic sieve when the content of 325-mesh fine powder is more than 65%-70%, and obtaining the yellow lignocelluloses when the content of the 325-mesh fine powder is more than 90%-98%. The yellow lignocellulose is suitable for a filling of wet PU (polyurethane) synthetic leather and can be used for endowing the synthetic leather with bright color, saving the use cost of color paste and reducing subsequent environment-friendly treatment cost and risk.
