Effect of enzymes on the scouring and bleaching properties of flax roves in supercritical CO2
Supercritical CO 2 (SC-CO 2 ) scouring and bleaching of flax roves was developed by using enzymes instead of chemical additives. Effect of dosage of enzyme, enzyme ratio, temperature, pressure, time and CO 2 flowrate on the scouring and bleaching properties of flax roves was investigated. The result...
