Effect of pectinase treatment on the properties of safflower and yellow printed silk fabric
In order to solve the technical problem of the deterioration of the hand feel style of natural dye-stuff printed fabrics,the reasons of the poor hand feel were analyzed.The appearance,air permeability,water absorption,bending stiffness and contact comfort of safflower yellow plain printed fabric were tested by pec-tinase treatment.The results showed that adding tannic acid to safflower yellow printing paste could effective-ly improve the color fastness to light,while the residual compounds such as pectin and polysaccharide on the fabric would affect the feel style of the fabric.Using pectinase to treat the printed fabric,the amount of pectin-ase was 2 g/L,and treated at pH 4 and 50℃for 3 h could effectively remove the residual substance,improve the air permeability and water absorption of the fabric,reduce the rigidity and roughness of the fabric,improve the smoothness,and improve the comprehensive feel of the fabric.
