Influence of novel thickening system EcopO-2 on hand feeling of pigment printed fabrics

The impacts of the new thickening paste EcopO-2 and other common synthetic thickening pastes on the hand feeling of pigment printed fabrics were compared,and the mechanism by which EcopO-2 significantly improves the hand feeling of the pigment printed fabrics was explored.The results showed that EcopO-2 plus fine binder can improve the hand feeling of pigment printed fabrics significantly.The stiffness test and PhabrOmeter determination indicated that the hand feeling of the pigment printed cotton or silk using ExopO-2 was near to or reached that of cotton or silk printed with the corresponding dyes.The weight change test,EDS elemental analysis and TG analysis of the printing paste membrane showed that EcopO-2 plays an important role in the hand feeling improvement.The basic reason lies not just in the extremely low solid content of EcopO-2,but in the small molecules of its inner phase material being able to get into the adhesive film acting plasticizing and softening role.
